Xu Lingzi was a Dou Saint powerhouse from a thousand years ago and also a famous array formation grandmaster at that time.
Among the many documents collected in the Treasure Pavilion of the Flower Sect, two areas were very rich: one was the cultivation of spiritual plants, and the other was array formations.
"Four-Sided Spirit Trapping Formation?"
Han Feng had never heard of this formation; his dabbling in this area was not very deep.
Even Xu Lingzi, a Dou Saint from a thousand years ago, he didn't know much about.
The Dou Qi Continent is full of hidden dragons and crouching tigers, with capable people emerging in large numbers. Although Dou Saints are rare, if integrated, there are quite a few.
Han Feng couldn't possibly know every Dou Saint thoroughly.
"Yes, the Four-Sided Spirit Trapping Formation, a low-level Rank 9 formation, can trap the spirituality within the formation, block the spread of soul power, and at the same time twist the spatial laws inside, causing a disordered sense of direction. No matter how the living beings inside explore, they cannot find a way out."
Elder Hua said word by word: "Before, I tried to break the formation from the outside, but instead I was pulled in by the formation. Actually, it's because the Four-Sided Spirit Trapping Formation has the ability to change freely and even move on its own!"
Ninety-nine percent of the formations in the world are fixed; this is common sense. It was the first time Han Feng heard of a formation that could move autonomously.
"No wonder. When I was in the Mountain and River Map earlier, I sensed that the root of the formation came from inside the fog. After extracting the fog, the formation of the Illusionary Forest was also lifted."
Han Feng said.
"This explains it."
Xu Lingzi being able to create such a peculiar formation and easily trap two Half-Saints indeed showed some capability.
Elder Hua looked at Han Feng, her red lips moving slightly, hesitating as if she wanted to say something to him.
Han Feng noticed the other party's strangeness and took the initiative to speak: "Does Elder Hua have anything else to say?"
"Yes... Mr. Han Feng, I want to study the Four-Sided Spirit Trapping Formation. Can you take me to the Mountain and River Map to observe it..."
"No problem."
Han Feng nodded.
Elder Hua looked at Han Feng expectantly, ready to enter.
"Is Elder Qing interested in this formation?"
Elder Qing smiled and shook her head: "I'll pass. I still have to deliver pills to Qingyun. You guys go."
Her array formation level had just entered Rank 8, which was quite far from her sister Elder Hua, a peak Rank 8 array formation grandmaster.
To study a Rank 9 formation, Elder Qing knew she was not qualified yet.
"Elder Hua, let's talk in detail in my room."
Han Feng said.
Elder Hua nodded, then waved goodbye to her sister.
Elder Qing watched Han Feng and Elder Hua go away, smiled gently, and flew in another direction.
Inside the room, Han Feng opened the Mountain and River Map and took Elder Hua into it.
With a thought, he dragged out the previously sealed fog.
"Elder Hua, I will probably leave tomorrow, so you only have one night."
"Ah?"
Elder Hua looked stunned: "But one night is not enough at all."
To initially comprehend a Rank 9 formation, it would take at least ten days or half a month, right?
"Mr. Han Feng, can't I go with you?"
Han Feng thought for a moment: "Next, I don't have particularly important things to do. If Elder Hua is willing to stay here to comprehend, it's not impossible."
"I am willing!"
Elder Hua nodded quickly, afraid that Han Feng wouldn't let her comprehend it.
"Alright, but shouldn't you tell Elder Qing about this?"
Han Feng felt that although Elder Hua was Elder Qing's older sister, her personality seemed somewhat naive, and usually, Elder Qing was the one who spoke and made decisions.
Sure enough, hearing this, Elder Hua nodded: "I should tell my sister, but she should agree."
"Then Elder Hua study here first. I'm going outside. Notify me anytime if there's anything; I can sense it."
Elder Hua nodded, her mind gradually focusing on the fog in front of her.
Han Feng left the Mountain and River Map and flew towards Hua Yu's residence.
Taking advantage of the night before leaving the Flower Sect, he should communicate more with Aunt Hua. Han Feng could feel that her feelings for him were even stronger than in his previous life.
But it made sense. In the previous life, Hua Yu was not seriously injured, nor did she suffer the torture of evil Qi for so many years.
She was the magnificent Flower Sect Leader, the confidante of Medicine Saint Yao Chen. Her interaction with Han Feng was more because of Yao Chen.
In the confrontation with the Soul Clan, to complete a mission, Hua Yu burst out with full strength to delay the Soul Clan's reinforcement troops, allowing Han Feng to successfully break through the Man Hall, destroy the Great Heaven Venerate, and win a round.
Unfortunately, Hua Yu died in this battle due to severe overdraft, and Han Feng also felt deep guilt towards her.
In the previous life, Hua Yu might not have had overly strong feelings for Han Feng, just treating him as an ordinary junior.
If she had become a Dao companion with Yao Chen, perhaps she would have treated Han Feng as her own child, but Yao Chen rejected her, so Hua Yu naturally wouldn't cross that emotional boundary and consider herself Han Feng's mistress.
But in this life, with Yao Chen's death and the significant changes in Hua Yu's experiences, Han Feng's appearance healed her physical and mental wounds. Regardless of whether she becomes a Dao companion with Yao Chen, Hua Yu believes from the bottom of her heart that Han Feng is her closest junior and someone she can trust unconditionally.
Han Feng arrived at Hua Yu's door. At this time, she should have rested, but she was still handling the government affairs of the Flower Sect.
"Aunt Hua, still busy?"
"Feng'er?"
Seeing Han Feng arrive, a look of surprise appeared on Hua Yu's face.
"Why are you here?"
"Came to chat with Aunt Hua."
Han Feng walked in.
Hua Yu stopped writing, stood up, and said: "I was very worried about your situation today, so I didn't finish processing, and had to do it at night."
As a Sect Leader, although she has the power to arrange her time freely, important affairs accumulated in the sect also need to be handled.
Hua Yu is obviously a responsible Sect Leader, which is why she handles official duties so late.
"Aunt Hua, nothing big happened in the Western Region of the Central Plains these years, right?"
"It's okay. The Hall of Souls and the Sky Profound Sect have been relatively well-behaved, but I heard that the Hall of Souls is secretly recruiting people, and their main base has been established in the Northern Region."
"Northern Region?"
Han Feng frowned slightly.
The Northern Region of the Central Plains is the closest region to the Northwest Continent. The main force of the Hall of Souls migrating there, could it be that they discovered something?
"I heard that the Wind Lightning Pavilion in the Northern Region is having a hard time now."
Hua Yu continued: "Originally, the Wind Lightning Pavilion was the local tyrant of the Northern Region, controlling major cities. Now that the Hall of Souls has entered the Northern Region, the position of the Wind Lightning Pavilion is very awkward."
Although the Hall of Souls will not easily expose the location of its branch halls and is only recruiting masters without intending to be the hegemon of a region.
But with such a behemoth behind them, even if it makes no move, it will make the Wind Lightning Pavilion feel like a thorn in the back and a fishbone in the throat.
Han Feng nodded gently.
Speaking of which, the Wind Lightning Pavilion is barely considered a first-class force among the famous forces in the Central Plains.
Unlike the Burning Flame Valley and the Ice River Valley, although the contemporary Valley Masters are only mid-level Dou Venerates, they all have impressive foundations.
Nor is it like the Two Sects, which have Half-Saints sitting in command.
Squeezing into the tail end of first-class forces is already its limit.
"It seems I have to go to the Northern Region later."
Hearing this, Hua Yu suddenly thought of something and smiled at Han Feng: "Feng'er, do you remember that next year is the Four Pavilions Grand Competition, and it will be held in the territory of the Wind Lightning Pavilion in the Northern Region?"
"Is the Four Pavilions Grand Competition next year?"
Han Feng was surprised. He did remember that the next Four Pavilions Grand Competition would be held in the Wind Lightning Pavilion, but he didn't expect it to arrive so soon.
"In these ten-plus years, the Yellow Spring Pavilion was destroyed, and the Sky Fire Pavilion replaced it. The replacement of old and new forces has made many people in the Central Plains curious about this Four Pavilions Grand Competition. Now that the Falling Star Pavilion is thriving again and produced so many strong people..."
When the status is unequal, the pressure is on the host.
Holding this Four Pavilions Grand Competition was originally intended to promote the prestige of the Wind Lightning Pavilion and tell everyone that the Wind Lightning Pavilion won the championship in the last competition.
But now anyone with eyes can see that the Falling Star Pavilion is the boss among the Four Pavilions.
Also thanks to the Four Pavilions Grand Competition being a stage for young people to compete; otherwise, there would be no need for this competition at all.
I'm afraid just by meeting, Venerate Lei would have to bow and scrape to Yao Chen, afraid of making this Medicine Saint dissatisfied.
The connections of an alchemist can be many levels higher than his own realm.
Yao Chen is already a Half-Saint now. The resources he can mobilize might involve Dou Saint powerhouses.
The tiny Wind Lightning Pavilion simply cannot afford to offend him.
"At that time, will Aunt Hua go to watch?"
Han Feng asked.
Logically speaking, a peak Dou Venerate and Flower Sect Leader like Hua Yu would not go to watch the Four Pavilions Grand Competition at all.
But if even Yao Chen participates, Hua Yu's presence is naturally reasonable.
"Will Feng'er go?"
Hua Yu did not answer directly.
Han Feng nodded.
"Going."
"Then I'll go too."
Hua Yu then answered with a smile.
The two chatted for a few more sentences, and then Han Feng prepared to get to the main topic.
He came to find Hua Yu actually for another relatively important matter.
"Aunt Hua, do you remember when I used the Sea Heart Flame to help you refine the Nine Element Spiritual Water last time?"
"Of course I remember."
Hua Yu nodded.
Hua Yu still remembers that night when Han Feng helped her cultivate.
The small turtle transformed from the Sea Heart Flame swam slowly in her body, not only assisting in refining the Nine Element Spiritual Water but also repairing some internal hidden injuries.
The Sea Heart Flame, having awakened the power of the Black Tortoise and containing powerful Water Laws, was of considerable help to Hua Yu's comprehension of the path of laws afterward.
"Then how about I help Aunt Hua cultivate again tonight?"
"Ah?"
Hua Yu was stunned.
Her current cultivation has reached the peak of Nine-Change Dou Venerate, recovering to the level before being eroded by evil Qi. One step further would be a Half-Saint powerhouse.
One night of cultivation seemed unable to decide anything.
But since Feng'er has this good intention, she naturally cannot refuse.
Hua Yu thought in her heart.
"Okay, I'll trouble Feng'er again tonight."
The two simply washed up, changed into casual clothes, and sat on the bed.
Facing Hua Yu, Han Feng slowly raised his hands and shook them violently, revealing the origin of the Sea Heart Flame.
Ripples spread around him. The powerful Water Attribute Laws made Hua Yu feel awe without fully understanding.
She had a premonition that tonight's cultivation would not be simple.
The full moon hung high.
In the dim room, wisps of blue brilliance emanated from the two.
Han Feng closed his eyes tightly, muttering something in his mouth.
Blessed by Dou Qi and soul power, these words flew into Hua Yu's ears, like a grand bell, every word deafening.
"What Feng'er is passing to me now is a cultivation method scripture!"
"At least it is... Heaven Class!"
Hua Yu was extremely shocked inside.
Heaven Class cultivation methods, even under the long-standing inheritance of the Flower Sect, only one was handed down, and it was Wood Attribute, incompatible with Hua Yu's origin Dou Qi.
In other words, the cultivation method scripture in Han Feng's mouth was Hua Yu's first contact with the concept of Heaven Class!
Hua Yu dared not be careless in the slightest, concentrating her mind and accepting Han Feng's scripture infusion.
To learn a Heaven Class cultivation method, it is not enough just to endure hardship; one also needs comprehension.
The first comprehension is particularly important. If one is not qualified, perhaps there is no fate.
Whether she can learn it and achieve something in this Heaven Class cultivation method depends on how much she can comprehend this time.
Facing Hua Yu, Han Feng reserved nothing, even inputting his own Dou Qi into her body to circulate on her behalf.
The cultivation method he passed to Hua Yu was none other than the "Black Tortoise Heavenly Ancestor Sutra".
This cultivation method is very powerful, but its value and function cannot be fully reflected on Han Feng.
But Han Feng was unwilling to pass it on to others casually. After all, it is a supreme cultivation method at the Heaven Class level. If fully comprehended, it can even surpass Heaven Class.
Once this kind of cultivation method spreads, it will cause a huge sensation.
So it can only be given to predestined persons.
Han Feng opened his eyes, and a trace of brilliant and deep blue light shot out from his pupils.
Aunt Hua, hope you are that predestined person.
This imparting of the Dao and teaching of skills lasted until the early morning of the next day.
The Dou Qi on Hua Yu's body had now turned into a sea-blue appearance, unlike before, which was greenish.
"Hu!"
Hua Yu exhaled a long breath and opened her eyes. Two Black Tortoise hexagrams flashed in her eyes.
"Black Tortoise Heavenly Ancestor Sutra", initiated!
Hua Yu did not let Han Feng's efforts of the night go in vain. She successfully comprehended the profoundness of the "Black Tortoise Heavenly Ancestor Sutra" and initially completed the cultivation of this method.
The beginning is always the hardest. As long as the first step is completed, the rest is the process of building walls and tiling. As long as she is willing to spend time, she can at least complete half of the scripture like the Nanli Empress Sikong Chan.
As for the later content, it depends on Hua Yu's own fortune.
But even relying on half a step of the "Black Tortoise Heavenly Ancestor Sutra" is enough for Hua Yu to break through to Half-Saint and aim for Dou Saint.
"Feng'er, Aunt Hua doesn't know how to thank you."
Hua Yu looked at Han Feng with complex eyes.
Passing down such a powerful Heaven Class cultivation method, even those Dou Saint mighty figures don't have this kind of fortune, right?
Judging from her comprehension progress last night, just the initiation is not weaker than the low-level Heaven Class cultivation methods in the sect.
Practicing further, I'm afraid it will only become stronger.
"Aunt Hua doesn't need to thank me. If you can fully comprehend the cultivation method, I should thank Aunt Hua instead."
Han Feng said with a smile.
In the entire Dou Qi Continent, there may be many who can comprehend the Divine Beast cultivation methods, but there are few whom Han Feng can truly trust.
Hua Yu is rare; in the list of people Han Feng trusts, she is one who can initiate the Divine Beast cultivation method overnight.
Although Han Feng's assistance played a big part, Hua Yu's own comprehension was also key.
If Hua Yu can cultivate the "Black Tortoise Heavenly Ancestor Sutra" to great success, her means of fighting against extraterrestrial demons will be incomparable to others.
While fighting against the Soul Clan now, Han Feng is also successively selecting personnel to prepare for the future Demon-Slaying War.
"Vermilion Bird Pure World Canon" corresponds to Sikong Chan.
"Black Tortoise Heavenly Ancestor Sutra" corresponds to Hua Yu.
"Azure Dragon Common People's Art" has not yet been selected. Ye Qingyun, who has initially comprehended it, can only serve as a backup for now; after all, her cultivation is not enough.
Elder Qing might succeed, but Han Feng's understanding of her is not deep enough, and the relationship between the two has not reached the level of complete trust, so he cannot pass it to her for the time being.
Inheriting this kind of supreme cultivation method, trust is the first priority, and strength is the second.
Currently, the best choice is to wait for Ye Qingyun to grow up. As long as she can initiate, she is the most suitable candidate.
Both Han Feng and Elder Qing place high hopes on Ye Qingyun.
