The three people were like beggars who suddenly saw an inexhaustible pile of money. Outside, a single top-grade crystal stone could make superpower users fight to the death, even lose their lives. Even at the Ancient Battlefield Ruins, killing a monster only gives a chance to obtain a top-grade crystal.

Lin Mo had seventeen top-grade crystal stones on him, but now looking at his own worth, it was no different from that of a beggar.

"With so many Energy Crystals, I can become a Middle-Level God," Yuri trembled all over with excitement.

"Advancing to the Innate Realm is just around the corner, hahaha," the Hongmen Ancestor appeared dementedly overjoyed.

Lin Mo was relatively calm. Like someone in a desert, money was not the most valuable thing; water was most important. The three of them still had no way to leave here. Were they to guard this pile of stones for a lifetime?

"With so many Energy Crystals, the key is how we leave this place," Lin Mo frowned and said.

Yuri and the Hongmen Ancestor were also startled. Now the three of them seemed to be holding wealth but waiting to die here.

"There must be a way out; we just need to regain some strength and then leave," the Hongmen Ancestor said.

Yuri nodded and suddenly his gaze fell to the side, "What's that place?"

Beside the entire basement, there were several heavy black metal iron doors. The iron doors, like outside, were engraved with some ancient runes, complex and mysterious.

"Let's go have a look; maybe we'll find something," Lin Mo frowned, cautiously approaching the iron door. It was very heavy, and he slowly pushed it open. Inside was a roughly twenty-square-meter room, seemingly a cultivation room.

At this moment, the black crystal stone Lin Mo had kept on him and hadn't put into his space ring yet—the one he got from killing the giant wolf—suddenly turned into streams of flowing black light and dispersed.

"Hmm?"

Lin Mo, Yuri, and the Hongmen Ancestor were all stunned.

"Can cultivation happen here?" The Hongmen Ancestor's eyes widened.

All three of them felt the energy leaking out into the air, being absorbed by them.

"Haha, we've got a way now. The three of us will cultivate in the secret chamber, and once we reach a certain level, we can leave here. By then, the suppressed strength will recover, and we'll all become invincible powerhouses," Yuri laughed heartily.

Lin Mo looked at the stone gate within the cultivation room. Next to the stone gate was an oval button. Lin Mo pressed his palm on it, and immediately golden streams flowed out from it, like golden water flowing down the complex patterns of the stone gate, just like rivers streaming into countless creeks. The golden liquid filled up the intricate patterns on the stone gate, shimmering with golden light.

"Hmm?"

The Hongmen Ancestor pushed hard on the stone gate, "Why can't I push it open now?"

"This should be the cultivation room's protective switch. Once the button is pressed, no one can break in to disturb a cultivator," Lin Mo explained, then pressed the button on the stone wall again.

Sure enough, the golden liquid slowly retracted back, gathering once more into the button.

"Lin Mo, although we have enmity, as peerless powerhouses, we already see mortals as nothing but ants. It's better to shake hands and reconcile, cultivate well here, and when we leave, we can aim for even higher realms," the Hongmen Ancestor suddenly looked at Lin Mo with a deep gaze.

"The Hongmen Ancestor speaks rightly. What are we three fighting for? The treasures here are enough for us to cultivate and advance. By the time we leave, we'll be invincible in the world. Fighting among us is just mutual destruction," Yuri also laughed heartily.

Lin Mo smiled, "Naturally, there are other cultivation rooms here. Everyone can find one to cultivate; if there aren't enough crystals, just take some from outside. It's a good thing."

"Good, we'll start immediately," the Hongmen Ancestor said, directly leaving the cultivation room and finding another place to cultivate, taking more than ten top-grade spiritual stones in with him.

Yuri did the same, both moving quickly as if fearing they'd miss out if they delayed.

Lin Mo also took a few top-grade crystal stones into the cultivation room, but he didn't start cultivating immediately.

Earlier, the Hongmen Ancestor's and Yuri's words were naturally not trusted by Lin Mo. If he was someone naive, he might have truly believed their friendly smiles.

But who was Lin Mo, having lived two lifetimes, a sly old fox among old foxes? How could he believe the words of the Hongmen Ancestor and Yuri? Their words were merely to avoid being disturbed during their cultivation.

He believed that once those two reached the ability to fly, the first thing they'd do would be to kill him and take all the crystals for themselves.

"Now, it's a matter of whose cultivation speed is faster," Lin Mo gritted his teeth.

Currently, they were in a place where their strength was suppressed, and the spiritual energy in their bodies was like stagnant water. Cultivating again was like starting anew as ordinary people.

"Who knows how long it's been since coming to this place. I'd better hurry and cultivate."

Lin Mo closed his eyes, activating the Qiankun Creation Technique within his body. The Energy Crystals placed in the secret chamber began to slowly emit streams of energy, which flowed gently into his body and were absorbed.

The injuries he had sustained a few days ago also started to recover under the abundance of energy, with his cells simultaneously brimming with vitality.

"At this rate, I can absorb two top-grade crystals a day, and as my strength increases, the speed of absorbing Energy Crystals will also be faster. I wonder if Yuri and the Hongmen Ancestor's cultivation speeds are faster than mine."

Lin Mo thought to himself.

During this time, everyone is racing against the clock. Should anyone gain enough power, the next time I go out to get top-grade crystals, I might be killed.

"Hmm?"

Time flows silently.

Everyone is cultivating in the secret chamber every day, only opening the stone gate of the Cultivation Room when the top-grade crystals are depleted to go out and get more. Of course, during this time, Lin Mo had only seen Yuri and the Hongmen Ancestor once each.

"Phew, finally reached the first layer of Qi Cultivation."

Lin Mo sighed. According to his calculations, reaching the first layer of Qi Cultivation took at least ten days. To confidently leave this place, he at least needed to restore his Foundation Establishment Stage strength.

However, he had been here for an unknown amount of time, and if he cultivated to the Foundation Establishment Stage strength before leaving, the people from the Qingxuan Sect might have already emerged from the Hidden Sect.

"No, I have to find a way to speed up."

Lin Mo frowned, but couldn't think of a better way. His current cultivation speed was already very fast.

"Fine, I'll go out and get some crystals first." Lin Mo glanced at the depleted crystals in the Cultivation Stone, then opened the stone gate and walked out.

At this moment, another stone gate opened simultaneously — it was the place where the Hongmen Ancestor was cultivating.

"Mr. Lin, you cultivate quickly, I must say I'm impressed." The Hongmen Ancestor said, his face glowing red.

Lin Mo raised an eyebrow, surprised that the other party's strength had reached the second layer of Qi Cultivation.

Could it be that the Hongmen Ancestor also has some secret cultivation method that allows for rapid strength enhancement?

"Isn't your cultivation even higher, Hongmen Ancestor?" Lin Mo smiled.

"Haha, just some original secret techniques. I believe I'll be able to cultivate to the Foundation Establishment Stage and leave here soon." The Hongmen Ancestor said, giving Lin Mo a meaningful look.

Lin Mo's heart skipped a beat. From the look in the other's eyes, he saw a murderous intent.

Lin Mo remained silent, selecting a few top-grade Energy Crystals and heading toward his secret chamber.

In the hall piled up like a small mountain were Energy Crystals, estimated to be at least tens of thousands of pieces, consuming ten pieces a day would take a hundred years.

"No, I must cultivate faster." Lin Mo returned to the secret chamber, and the first thing he did was activate the seal on the chamber.

Having observed the seal on the chamber's stone gate, Lin Mo realized that even with Foundation Establishment Stage strength, it couldn't be broken. But if the Hongmen Ancestor or Yuri's strength greatly surpassed his own, and they stopped entering the chamber to cultivate, the next time he went out to collect Energy Crystals, he would surely be killed by them.

Now, everyone's strength is relatively close, each person harboring their own intentions. Without enough strength, everyone hides in their chambers to cultivate.

"Continue cultivating."

Lin Mo placed the Energy Crystals in front of him. In the secret chamber, these Energy Crystals would transform into streams of energy to be absorbed by the cultivator, and on these walls, who knows what kind of runes were inscribed to prevent the energy from leaking out.

Presumably, this place was a former cultivation area for an organization akin to a Sect, and with so many Energy Crystals, only the elite among elite disciples in a Sect could come here to cultivate, without worrying about a shortage of Energy Crystals.

"Hmm?"

Suddenly, Lin Mo's face showed a look of surprise. Having reached the first layer of Qi Cultivation, he could now cultivate inner sight. Under inner sight, he could see abundant, pure energy surging through his meridians, but he was surprised to find his bones covered in purple patterns, which began continuously twisting, with the purple patterns resembling tree

leaves and branches, slightly protruding from the bone.

Blood Demon Vine. Emperor!

Abruptly, the energy in the cultivation room was drawn in like a vortex, starting to surge in relentlessly!

Initially, when one begins cultivation, the body is like a vessel, naturally absorbing much less energy since the body needs time to digest and transform the energy into its own.

But the Blood Demon Vine. Emperor was frantically devouring energy, seemingly in ecstasy, with tendrils and leaves continuously growing, transforming, and evolving. Its absorption speed was almost three times that of Lin Mo's self-cultivation.

More excitement awaits tomorrow.
