["Help me, Grand Elder!"]
[Seeing that he needed to dig a hole downward, Yu Xiaogang took out a tool and shoveled a few times. Realizing the progress was too slow, he immediately called for reinforcements.]
["What happened?"]
[Hearing Yu Xiaogang's call, the Grand Elder immediately stopped what he was doing and looked up at Yu Xiaogang.]
["Grand Elder, I'm planning to find an immortal grade herb to consume. Little Dragon sensed that there's something else beneath this ground, and it's what suits me best."]
["The immortal grade herb that suits you best?"]
[Upon hearing Yu Xiaogang's words, the Grand Elder quickly walked to Yu Xiaogang's side.]
[Currently, in the Grand Elder's eyes, Yu Xiaogang was the future of the Sect.]
[The herb most suitable for the Sect's future?]
[Just watch me dig you up!]
[And so, the next phase was the bustling hole-digging session.]
[With the help of the Grand Elder, a quasi-Titled Douluo, it didn't take long for the two of them to dig a large pit.]
[Later, Lin Lang and Dugu Bo were awakened by the commotion. After understanding the situation, the two of them also took turns joining the digging team.]
[In this way, the group dug and dug, reaching a depth of over ten meters underground.]
[Ding!]
[A crisp sound echoed in everyone's ears.]
[Looking at the stone below, the Grand Elder tapped it again with the iron shovel in his hand.]
["It's likely a very large rock."]
[Having judged the specific situation, the Grand Elder and Yu Xiaogang frowned.]
[A massive rock was definitely a huge obstacle for digging a hole.]
["Should we just destroy it?"]
[Lin Lang asked from the side.]
["Don't!"]
["No!"]
[As soon as Lin Lang finished speaking, Yu Xiaogang and the Grand Elder spoke up at the same time.]
["The immortal grade herb Xiaogang needs is right below. If we rashly destroy this rock, what if the immortal grade herb Xiaogang needs gets crushed?"]
[The Grand Elder glared at Lin Lang crossly.]
[Being glared at, Lin Lang scratched his head sheepishly.]
["Then let's change direction. No matter how large this rock is, it must have limits."]
[With the order given, the group resumed their excavation work.]
[Before long, the edge of the rock was found. The group dug down along the edge and then unearthed a stone wall.]
[Tapping on the stone wall, Yu Xiaogang and the others could hear a faint sound, proving there was an empty space behind the wall.]
["So a secret chamber is actually hidden underground here?"]
[The Grand Elder said.]
[Beside him, Yu Xiaogang also tilted his head in thought.]
[The spring composed of ice and fire, plus the valley, formed an environment very suitable for the growth of medicinal herbs.]
[But how was such an environment formed?]
[Where was the source of that ice and fire spring?]
[It couldn't have just appeared out of thin air, could it?]
[The things appearing one after another continuously piqued Yu Xiaogang's curiosity. He desperately wanted to know the secrets hidden within this valley.]
[After realizing the stone wall was a secret chamber, the group began to dig around the chamber's perimeter.]
[Either to find an entrance to the secret chamber or to find a weak point in the stone wall to break through.]
[In any case, their curiosity about what was inside the secret chamber had already been piqued.]
[After working for so long, they couldn't just let their efforts go to waste, could they?]
[Soon, under everyone's continuous exploration, the area around the stone wall was hollowed out. After some investigation, they found the weakest point of the stone wall.]
[In order not to damage the immortal grade herb inside, the Grand Elder took charge personally. With his Martial Soul Possession active, he began to pick at the stone wall bit by bit, breaking the intact wall into palm-sized pieces to clear a path.]
[Seeing the Grand Elder's cautious manner, Yu Xiaogang wanted to say several times that there was no need to be so careful.]
[But he never said those words.]
[To be honest, seeing the Grand Elder like this, Yu Xiaogang was quite moved.]
[Although Yu Xiaogang knew that in the Grand Elder's heart, the Blue Lightning Tyrant Dragon Sect would always come first.]
[The reason he was being so well-cared for was that he had shown potential and the ability to take the Sect to the next level.]
[Because he could make the Sect stronger and become its pillar, he received such care.]
[But as the recipient of such care and concern, it was hard for Yu Xiaogang not to be moved.]
[Under the Grand Elder's cautious movements, it didn't take long for the stone wall to become thinner. At the same time, the excavated stone blocks gradually turned into something like Red Crystals.]
[Through the Grand Elder's judgment, these Red Crystals were formed from a mixture of spirit power, blood vitality, and the like.]
[Looking at these Red Crystals, everyone's expressions turned serious.]
[They had seen spirit power mixed with other things to form Ore-like substances before.]
[But mixed with blood vitality?]
[That was rare.]
[And what exactly could be in this secret chamber to provide such a vast amount of blood vitality?]
[Finally, as another Red Crystal was removed, a gap was finally opened in the secret chamber behind the rock wall.]
[It was at this moment.]
[Whoosh!]
[A thick aura surged out from the gap, blowing directly against the Grand Elder, who was closest.]
[Blown by this aura, the Grand Elder felt his blood vitality surge.]
[At the same time, his body involuntarily shifted from partial Dragonization to full Dragonization.]
[Standing behind the Grand Elder, Yu Xiaogang was the second to feel this aura, and the blood vitality in his body also surged.]
[And because his own strength was weaker, his blood vitality surged even more violently than the Grand Elder's.]
[Beside them, Little Dragon, who was also hit by the aura, took a deep breath, as if wanting to inhale all of this aura into its body.]
["Awoo! \(≧▽≦)/"]
[A joyful roar brought the dazed Grand Elder back to his senses.]
["This... just being hit by the aura caused such a violent reaction?"]
[The Grand Elder glanced at Yu Xiaogang. After confirming he was alright, he swallowed hard with some difficulty.]
[He couldn't imagine what kind of powerful immortal grade herb was hidden inside.]
[However, he was certain that the immortal grade herb inside must be extremely suitable for Spirit Masters with Dragon-type Spirits.]
[Taking a deep breath to suppress his boiling blood vitality, the Grand Elder began digging again. Soon, a passage that allowed them to enter the secret chamber was formed.]
[With the entrance formed, Yu Xiaogang stepped forward and raised his hand to condense a ball of light, then controlled it to enter the secret chamber through the entrance.]
[The light illuminated the situation inside the secret chamber, and then Yu Xiaogang and the others gasped.]
[The scene inside the cave was truly a bit too horrifying.]
[A large number of skeletal remains that had long since turned into white bone were piled up in the secret chamber. Looking at the size of those remains, they were likely all ten-thousand-year Spirit Beasts.]
[At the same time, the stone walls around the secret chamber were completely covered by the Red Crystals from before.]
[By now, they also understood how those Red Crystals were formed.]
[With so many Spirit Beast remains, they certainly provided enough blood vitality.]
