Mo Tianheng openly praised Ye Liuyun for his solid Xuan Yuan, which indicated that Mo Tianheng was aware of the importance of the quality of true essence.

"But why didn’t he focus on enhancing the quality instead of the cultivation level?" Ye Liuyun speculated internally that it might be related to that ancient demon.

This is a major taboo for martial cultivators. Pursuing speed alone can lead to an unstable foundation. Ye Liuyun was confident that with his abundant Xuan Yuan, he could emerge victorious in a head-on clash with Mo Tianheng. Mo Tianheng’s foundation was already unstable, and it might not take much to make him falter.

Mo Tianheng also realized that his true essence was no match for Ye Liuyun’s, so he immediately harnessed the power of heaven and earth and continued his attack on Ye Liuyun.

Ye Liuyun’s control over the power of heaven and earth wasn’t as strong as Mo Tianheng’s, so in addition to using secret yuan spirit techniques to limit Mo Tianheng’s ability, he also wielded his Demon Slayer Blade, applying his blade intent to barely hold his ground against Mo Tianheng.

The two ended in a stalemate again. Then, their battle accelerated, and they both started using power of bloodline. Ye Liuyun’s power of bloodline, capable of a closed-loop cycle, was somewhat stronger than Mo Tianheng’s.

Subsequently, they both employed spatial power, darting around the starry sky. Apart from Lei Ming, who could often spot them with his golden eyes, the other beasts lost track of their presence. Occasionally, they’d look towards the sound of the clash, only to find Ye Liuyun and Mo Tianheng had changed locations once more.

"This guy is genuinely strong!" The soul of the ancient demon watched their battle closely, offering advice to Mo Tianheng.

"How about trying a soul attack?" the ancient demon suggested to Mo Tianheng.

"No, he has protection in his sea of consciousness!" Mo Tianheng replied. He was aware of Ye Liuyun’s defenses and didn’t dare to launch a soul attack on him.

In fact, the ancient demon knew too that one of its soul fragments had been destroyed last time when it entered Ye Liuyun’s sea of consciousness. At that time, Ye Liuyun’s soul power was nowhere near as strong as it is now.

Without realizing it, their battle had taken them farther away. Lei Ming and the others couldn’t spot their figures, so they returned to assist Liu Yun Yao in attacking the Barbarian army.

Ye Liuyun had drawn Mo Tianheng far away, and seeing no one else around, he began to prepare for his move against Mo Tianheng.

Relying on the tacit understanding and trust between him and Mo Tianheng, he believed that by deliberately leading Mo Tianheng away, it was impossible for Mo Tianheng not to notice. The fact that Mo Tianheng followed him suggested he was cooperating.

First, Ye Liuyun let the soul of his avatar enter his sea of consciousness, then instructed the Demon Suppressing Tablet to absorb the demonic energy from Mo Tianheng’s demon heart, avoiding the absorption of any other forces.

After everything was arranged, he utilized his time powers to freeze time. Then, he released the Demon Seal Stone, pressing it onto Mo Tianheng’s head.

Next, his divine soul rushed into Mo Tianheng’s consciousness, using the power of Buddha’s light to wear down the ancient demon’s soul.

The strength of the ancient demon’s soul was twice that of Mo Tianheng’s, completely suppressing his soul power. Ye Liuyun planned to deplete it before dragging it into his own consciousness to devour it.

However, the power of the time freeze was suddenly broken!

It wasn’t that Ye Liuyun’s time powers had failed; it was that the ancient demon’s heart was too strong, directly breaking through Ye Liuyun’s time limitation.

In a moment of urgency, Ye Liuyun acted without hesitation. His soul rushed forward, grabbing the ancient demon and trying to drag it out.

"Help me drag it into my consciousness!" Ye Liuyun’s soul shouted for assistance to Mo Tianheng’s soul, while simultaneously releasing the power of Buddha’s light to disrupt the ancient demon’s soul, not treating Mo Tianheng as an enemy at all.

"A good opportunity, let’s join forces to destroy its soul!" the ancient demon called for Mo Tianheng’s help as well.

Ye Liuyun’s soul power was even weaker than the ancient demon’s. Without relying on the power of Buddha’s light, he would have been defeated on the spot. At this time, Mo Tianheng’s decision was undoubtedly crucial.

Yet, Mo Tianheng acted silently, aiding Ye Liuyun in pulling the ancient demon’s soul out of his own consciousness.

"Are you crazy? I’m your master! I’ve taught you so much..."

The ancient demon didn’t expect Mo Tianheng to join forces with Ye Liuyun at such a moment. He couldn’t understand why Mo Tianheng did this. Had he discovered his intentions after all the enhancements he provided?

But Ye Liuyun and Mo Tianheng held onto its soul tightly, giving it no chance to escape, directly pulling it into Ye Liuyun’s consciousness.

Mo Tianheng didn’t hesitate to follow them inside either. Moreover, the golden light of the All-Gods Order did not envelop him. Only when he saw the ancient demon being enveloped by the golden light of the All-Gods Order did Mo Tianheng’s soul exit Ye Liuyun’s consciousness, returning to his own body.

At this point, the Demon Seal Stone also began absorbing the demonic energy from Mo Tianheng’s heart. The demonic energy in that heart was overwhelming; without the ancient demon, it was extremely challenging for Mo Tianheng to control it on his own.

After the Demon Sealing Monument absorbed for a while, the demonic energy within the heart began to quickly dissipate.

"That’s enough!" Mo Tianheng shouted, and Ye Liuyun immediately retracted the Demon Sealing Monument.

Mo Tianheng immediately sat cross-legged to thoroughly refine the ancient demon heart. Ye Liuyun stood by to guard him.

After a long time, Mo Tianheng completely refined the heart and got up to greet Ye Liuyun.

"I knew it, in the end, I’d have to rely on you to help me!" Mo Tianheng smiled at Ye Liuyun.

The two exchanged smiles. The trust they had developed was fully demonstrated through this battle. Without absolute trust, such a method would not have been possible.

"How did you manage to provoke it?" Ye Liuyun asked Mo Tianheng in puzzlement.

Mo Tianheng immediately recounted the events: "It mainly happened because my cultivation level was too low at the time, so I didn’t notice the problem within the ancient demon heart. Also, I was eager to increase my strength, so I initially didn’t pay attention.

By the time I realized it, it was too late. I had to follow the ancient demon’s instructions, boosting my strength while looking for an opportunity. If I hadn’t met you, my cultivation path might have ended in failure.

That ancient demon was essentially using me as a vessel, like forcing a seedling to grow faster."

It turned out that Mo Tianheng had already understood the ancient demon’s intentions but couldn’t break free from it. He had to bear with it while waiting for a chance. His previous attitude towards Ye Liuyun was all a facade. Once he met Ye Liuyun, he knew the opportunity had come.

When Ye Liuyun led him away from the crowd, Mo Tianheng obediently followed, waiting for Ye Liuyun to take action and destroy the ancient demon’s spirit.

Ye Liuyun also understood the course of events.

"I really admire your endurance; to be able to hold out this long! If it were me, I probably would have fallen out with that ancient demon and been devoured by it.

But your cultivation level is already unstable. Even if you try to remedy it now, the height you can reach in the future may be limited. Also, the speed at which your soul, body, and power of bloodline have increased is too fast, and all these are quite unstable. You need to consolidate them properly."

Mo Tianheng nodded in agreement: "It is what it is, and there’s no other way. I can only try to remedy it as best as I can! However, I won’t give up just like that. Maybe a miracle will happen!"
