Without waiting for Bu Dong to speak, he continued, "Regarding the crystal core, if it hadn't been stolen, you should not even be aware of it. Remember, never harbor any thoughts about the crystal core. Each crystal core is linked to countless lives. To meddle with any of them would mean incurring a tremendous cause and effect."

Bu Dong asked at this point, "Father, what about the one who stole the crystal core? Isn't he afraid of incurring such tremendous cause and effect?"

From the throne, Bu Xuye said, "He is under mysterious laws. He likely does not belong to this realm, and the power of cause and effect has limitations. When it goes beyond certain limits, when the laws of the entire world are vastly different, the power of cause and effect will significantly weaken. Therefore, he is not afraid."

"If that's the case, why don't you, along with the other two major forces and the Eternal Master, find and kill him?" Bu Dong asked.

"Can't find him." Bu Xuye frowned and said, "That person's movements are elusive, impossible to predict. However, we can verify one thing; he has not left the ancient god's corporeal world."

"Hmm?" Bu Dong was slightly taken aback.

Bu Xuye said, "Because he cannot leave. This world of the ancient god is easy to enter but difficult to exit. Without finding that hunt knife, he has no way to leave!"

It's that hunt knife again!

At the thought of that knife, Bu Dong felt a headache.

"What's the matter?" Bu Xuye looked at Bu Dong with indifference. Though his gaze was clear, it sent a chill to Bu Dong's heart.

He quickly said, "Father, I'm fine. I just think... in that case, we must find that hunt knife before he does."

"Indeed, that knife was once with us in the past. However, it is too ominous. Even the Eternal Master could not suppress this ominous artifact and had to let it go, allowing it to leave. Based on our tracking, it should have entered the ancient god's heart world. However, now that world, the crystal core is also gone. But it wasn't taken by that thief. The Eternal Master and we speculate it was taken by the one holding the ancient god's hunt knife. That person may not be of high realm, but very strong. Yet, he is certainly no match for the one who stole the crystal core. Hence, I'm giving you a new task now."

"Please tell me, Father." Bu Dong stood up, face full of respect.

Bu Xuye said, "You bring people, a large number of people, and find the person holding Pangu's hunt knife, then protect him well and bring him back to the Eternal Land. You must be ahead of the crystal core thief."

Bu Dong couldn't help but ask, "Father, regarding that hunt knife, apart from that person, is there truly no one else in this world who can wield it?"

Bu Xuye looked coldly at Bu Dong, "Do not indulge in forbidden thoughts."

Bu Dong immediately felt a chill run through him and quickly said, "I was just curious..."

"That knife can only be wielded by someone with both Pangu's essence blood and qi movement. In this world, which is the ancient god's corporeal world, the one who can wield that knife is the one most closely related to the ancient god! Before him, the closest were the Eternal Master and us three, but we only have a small portion of the ancient god's essence blood. The Eternal Master has a portion of the ancient god's qi movement and a bit of essence blood. None of us can wield that knife." Bu Xuye looked at Bu Dong, "Hence, do not attempt to make any moves on him. I ask you to bring him back, not to protect him; he needs no one's protection! We are looking for him, hoping for a chance to leave before the ancient god's corporeal world crumbles."

Bu Dong felt a sense of powerlessness. At their level of cultivation, they still felt unable to control their own fate. This feeling was truly uncomfortable.

But he dared not defy his father's decree.

In the Eternal Land, the Eternal Master rarely concerns himself with worldly affairs, leaving everything for the three major powers to handle. So, any law issued by the three major powers is essentially the highest decree in the Eternal Land.

Bu Dong set out with many people; with his father's command, he had to earnestly search.

In the Shenjian World.

After so many years of development, someone is finally about to break through!

This person is neither the astonishing Drifting Empress nor the Chu elder who reigned over the Yanhuang region across ten thousand ages, but Chu Mo's master... the Demon Lord!

This result surprised many. Although the Demon Lord was very powerful, many believed his talent wasn't unparalleled. In terms of pure talent, he wasn't even as good as Qi Xiaoyu and Shui Yiyi, the "rising stars."

Yet, curiously, the first person in the Shenjian World to ascend to the supreme realm is the Demon Lord!

However, there's one thing that everyone is questioning.

Whether the Cangqiong Shenjian World is sufficient to support the Heavenly Tribulation of a supreme cultivator?

Chu Mo hasn't appeared for many years; everyone only knows that Chu Mo must still be alive because the Shenjian World remains stable.

Concerning the tribulation, the Demon Lord wanted to discuss it thoroughly with Chu Mo.

While refining an invincible battleship with the intelligent brain, Chu Mo received the message from the Demon Lord, and he was slightly stunned.

Somewhat surprised, how many years has it been... Unexpectedly, his master is about to break through? This was indeed enormous good news for Chu Mo.

Even if the Demon Lord wouldn't be able to help Chu Mo much after his breakthrough, the fact that his close ones could ascend to the supreme realm was immense good news for Chu Mo.

Thus, he directly summoned the Demon Lord out of the Shenjian World.

After the Demon Lord emerged, he looked at the steel fortress-like structure in the distance void and was a bit dumbfounded.

Because within that steel fortress, there were even occasional massive electrical surges flickering.

Upon a closer look, the Demon Lord discovered that those materials were not ordinary steel at all, but actual divine metal. Top-tier artifact forging materials that are extremely rare across the entire universe!

"What's this?" the Demon Lord looked at Chu Mo.

Chu Mo smiled and said, "Come, Master, let me introduce you..."

With that, he directly dragged the Demon Lord toward the steel city.

On the way, Chu Mo recounted some events from these past years to the Demon Lord.

From this, the Demon Lord finally understood that since Chu Mo left the Tunnel World years ago, he had experienced so many events till today. Moreover, the things he experienced had already completely surpassed the Demon Lord's understanding.

Thinking about how he was still troubled about how to ascend to the Supreme realm, the Demon Lord couldn't help but sigh, "If I could help you, that would be great. Unfortunately, people like us can only hold you back."

Chu Mo said, "Master, please don't say that. I think you all can definitely help me. It's just a matter of time."

Afterward, Chu Mo introduced the Demon Lord to the intelligent brain. Since meeting Chu Mo, it was the first time the intelligent brain saw people around Chu Mo. It was also very happy, working joyfully while chatting with the Demon Lord.

The Demon Lord was also astonished by the existence of the intelligent brain, finding it unimaginable that such a form of life existed in this world.

He was equally curious about everything related to the intelligent brain.

It wasn't until a long time later that the Demon Lord remembered his purpose for seeing Chu Mo, directly asking, "Would undergoing the tribulation here cause too much commotion? Can the Divine Mirror World withstand the Heavenly Tribulation of the Supreme realm?"

Chu Mo nodded and said, "The Divine Mirror World can definitely support the Heavenly Tribulation of the Supreme realm. Master should also undergo the tribulation there because you are the first person to undergo the Supreme Heavenly Tribulation in the Divine Mirror World. This can greatly inspire other practitioners in the Divine Mirror World; more importantly, you can leave your Dao in the laws of the Divine Mirror World!"

The Demon Lord looked at Chu Mo, his expression becoming serious, "What do you mean?"

"What I mean is, the more people undergo tribulation there, and the higher their realms, the more complete that world will become. It can become even more beautiful!" Chu Mo looked at the Demon Lord with a smile and said, "Some things, an excess is as bad as a deficiency, but having none at all is also not acceptable."

The Demon Lord, hearing Chu Mo's words, suddenly fell into deep thought. He suddenly understood a bit, and had a moment of realization. Looking at Chu Mo, the Demon Lord's eyes lit up, "I understand, a complete large world, with too many practitioners, will deplete this world's energy. Even if practitioners can reincarnate, the consumed energy ultimately disappears. Even if one day, the practitioner's life expectancy ends, and they return to dust, it's impossible to return all the consumed energy back to Heaven and Earth."

Chu Mo nodded.

The Demon Lord continued, "But if a large world has too few high-realm practitioners, it will also lead to problems, with the Heavenly Dao laws being insufficiently complete. It could easily collapse!"

Chu Mo nodded again, somewhat understanding why the first person to transcend from the ancestral realm to Supreme was his master.

The Demon Lord's talent might not be top-tier, but his comprehension was extraordinarily rare in the world.

Some things, when spoken, seem simple. But without guidance, understanding the truths contained within for the first time is an extremely difficult process.

Otherwise, why from ancient times to today, very few sage masters appear. Most people follow along the paths of those few sage masters.

After figuring these things out, the Demon Lord didn't stay any longer. He turned around and returned to the Divine Mirror World. He didn't even let Chu Mo enter to protect him.

Because the outside was not very peaceful, it was better for the Divine Mirror World's aura not to be leaked out too much.

However, with his master undergoing tribulation, Chu Mo couldn't ignore it completely. So, a strand of his spiritual power followed the Demon Lord back to the Divine Mirror World.

After the Demon Lord returned, he almost immediately went to undergo the tribulation.

Over the years, it wasn't that no one underwent tribulation in the Divine Mirror World; in fact, many people from the Chu Clan's royal family had achieved ancestral realm cultivation here.

But the Supreme Heavenly Tribulation… was the first!

Above the high heavens of the Divine Mirror World, the tribulation clouds almost covered a hundred billion miles of sky!

The Demon Lord's unparalleled figure stood proudly beneath the tribulation clouds.

And there's more!
