No matter how you looked at it, Yusei's power had now reached a new level. The various abilities of the Rinnegan significantly enhanced his combat capabilities.
It wasn't just the abilities of the Deva Path, as the others like the Animal Path, Human Path, Naraka Path, Preta Path, and Asura Path, all possessed their own formidable strengths.
Animal Path could summon powerful creatures from countless worlds.
Human Path specialized in attacks against the soul, allowing the enslavement of others' spirits.
Naraka Path could heal the user, enabling true and complete restoration, and even manipulate life and death.
Preta Path could devour various forms of energy to replenish the user.
Asura Path could materialize all kinds of weapons, even modern technological ones… a path truly dedicated to slaughter.
Furthermore, as his own Rinnegan, it inherently possessed associated Dojutsu.
Just as two Mangekyo Sharingan could give rise to Susanoo Armor, two Rinnegan also gave birth to a special ability.
Yusei's Rinnegan's unique Dojutsu… Phantom Doppelganger.
This ability could be considered somewhat limited, yet also incredibly powerful.
Its effect was to create a controllable, physical doppelganger identical to the main body.
The doppelganger possessed all the abilities of the main body, but their potency was reduced by half.
The most practical aspect was that if the main body suffered a fatal injury, the main body could instantly transfer its consciousness to the doppelganger.
Simply put, any fatal damage sustained by the main body could be completely transferred to the doppelganger.
The doppelganger would substitute for the main body in enduring the fatal wound.
Because it was a perfect copy, the fatal trauma it bore included all forms of damage, including spiritual, conceptual, and so on.
Naturally, the distance between the main body and the doppelganger could not exceed one kilometer.
Beyond that range, control was lost, and the doppelganger would automatically dissipate.
A doppelganger that had sustained damage would enter a dormant state for twenty-four hours to recover, after which it could be summoned again.
Although it was physically visible, in terms of utility, it was more practical than Uchiha Madara's Limbo: Border Jail.
After reviewing his new abilities, Yusei temporarily reined in his excitement and prepared to return.
Animal Path couldn't be used immediately, as he hadn't yet utilized its power to capture creatures from other worlds.
From the knowledge imparted by Animal Path, Yusei learned that summoning creatures required mentally conceptualizing the specific abilities, appearance, and other details of the desired being.
Additionally, the summoned creature's power had to be weaker than his own, share a similar power source, or the creature itself must harbor goodwill towards him.
Considering the complexity involved in summoning creatures via Animal Path, Yusei decided to hold off on using it for now.
He swiftly flew back to the villa and went straight to his room on the second floor.
Athena was already awake, having returned to her complete, mature goddess form.
She was sitting at the dressing table, gazing thoughtfully at her reflection in the mirror.
Seeing the beautiful and captivating Athena, Yusei quietly approached from behind and embraced her, burying his face in her hair and inhaling her pleasant scent.
Athena, having regained her divine power, was naturally aware of Yusei's presence. She didn't resist, contentedly enjoying the moment of peace.
After a while, they separated. Athena looked at Yusei, about to speak, when she suddenly froze.
Her eyes had immediately caught the change in his.
"Yusei, your eyes..."
"You noticed? That's right, this is a new power I acquired."
Yusei smiled, gently touching his eyelids.
Athena nodded, her gaze curious as she studied his eyes. She truly sensed a formidable power within them, one that even she found pressuring.
While she was happy that Yusei had grown stronger, her nature as the Goddess of Wisdom compelled her to notice the peculiarity in his left eye.
"Yusei, has your left eye been exposed to Divine Power before?"
"My left eye?"
Athena's question gave Yusei pause. He immediately turned to look in the mirror.
Now that he thought about it, he hadn't yet seen his own reflection. Hearing her words, he wanted to see for himself.
His right eye was a standard Rinnegan, purple with concentric circles. His left eye was also a Rinnegan.
However, the left one was different. Upon the rippled pattern were additional complex, intricate, and subtle divine markings. These were the same patterns that had appeared when his Eternal Mangekyo evolved.
'Did they upgrade along with the circles?'
Yusei touched his left eye. He could indeed feel that its power still contained the ability to 'record' the abilities of others.
"Nana, do you know anything about these divine markings?" Yusei asked, holding Athena curiously.
Athena nodded, "This should be power given to you by Pandora. But why it has manifested in your eyes, I do not know."
"Will there be any side effects? Hidden dangers, for instance?"
"There will not. My wisdom tells me that the power of the divine markings has been fully absorbed by your eyes, transformed into pure divine energy without any impurities," Athena replied with a smile.
"That's a relief."
Yusei let out a sigh. He had a vague memory of encountering the woman named Pandora, but the details were hazy.
Regardless, as long as this power held no hidden dangers, it was fine.
He helped Athena to her feet, his movements gentle. Although Athena was technically his 'god-servant', Yusei treated her with the utmost care and respect.
A goddess of her intellect and grace naturally commanded attention, and it was easy to become captivated by her wisdom and beauty.
Seeing her lover's solicitousness, Athena smiled faintly and said nothing more, allowing him to guide her steps.
In truth, with her divine body fully restored, she was perfectly fine. But she felt this was a perfect opportunity to enjoy Yusei's attentiveness, so she didn't say anything
Lunch was prepared by the professional maid, another exquisite meal.
After lunch, Athena abandoned her pretense of being 'gravely injured', and together with Yusei, began planning their entry into the Netherworld.
While entering the Netherworld was difficult for ordinary humans, it was a simple matter for Athena.
Yusei instructed Erica and the others to assist Luo Hao in her assault on the History Compilation Committee, while he and Athena would go directly to find Susanoo.
The clash between a Campione and a Heretic God would undoubtedly have massive repercussions, so Erica did not insist on accompanying them.
After receiving Yusei's orders, she went to contact Lu Yinghua to coordinate the attack.
Meanwhile, Yusei and Athena made their final preparations to enter the Netherworld.
