Su Su didn't expect that Bu Shecai wouldn't be angry, but instead nodded and said, "Boss, he really is Old Qu's successor! I can guarantee it."

That mouthful of saliva I spat was the secret code agreed upon between my master and Bu Shecai.

Moreover, this code was actually set by Bu Shecai himself.

He owed my master a life back then and agreed to repay it to my master's successor in the future.

To prevent others from impersonating, he set up such a code with my master.

When I heard my master mention this, I specifically asked, "Is this something a normal person would do?"

My master's answer was, "That's exactly why normal people wouldn't do it, that's why we're using it to connect."

"Bu Shecai himself said: If your disciple doesn't trust you one hundred percent, he would never take this code seriously. Therefore, the person who can use this code to find me must be a disciple who is treated like a son and respects you like a father."

"Apart from this kind of relationship, even a disciple who harbors ulterior motives towards you wouldn't believe your words."

Later, after thinking about it carefully, I felt that Bu Shecai's words made some sense.

It's just that I didn't expect that after so many years, I would really encounter such a weirdo.

Yu Wusheng, sitting in the distance, said, "Young friend, come and have a chat!"

I walked past those Jie Ming Ren (Yang Jian Jie Ming Ren) who looked like clay sculptures and sat down in front of Yu Wusheng.

Yu Wusheng spoke first, "Young friend, tell me about the current state of the art world!"

I briefly described the situation in the art world, and Yu Wusheng couldn't help but sigh, "So, the battle of Liangjie Mountain (Two Worlds Mountain) is already so close?"

"Young friend, do you know why there are Jie Ming Ren in this world?"

"I know!" I recounted the secrets I had heard from Ye Qianyang.

Yu Wusheng then said, "I entered the Zhenmo Tower (Demon Suppression Tower) for the secrets of the Jie Ming Ren, but I received a heartbreaking message here."

"Back then, when I found that group of missing Jie Ming Ren, they were all still alive."

"Some of them told me that the reason why the Jie Ming Ren encountered an unprecedented disaster was because of the dynasty and the underworld."

"Back then, the underworld adopted Ye Qianyang's suggestion to indirectly support the art world against the Heavenly Soul Calamity by capturing Earth Souls in exchange for lifespans."

"However, the underworld quickly regretted it."

"Because they didn't want to see the result of the Jie Ming Ren becoming immortals."

Hearing this, I couldn't help but frown, "A cultivator not becoming an immortal is an ancient law, how could a Jie Ming Ren become an immortal?"

Yu Wusheng said, "Some say: Reaching a lifespan of over five hundred can lead to immortality, and some say: Reaching a lifespan of over a thousand can lead to immortality."

"Although no one has verified this result, it is undeniable that whether it is a person or something else, if its lifespan exceeds its due limit, it means that it has transcended mortality and entered the path of immortality."

After a little thought, I believed Yu Wusheng's statement.

In myths and legends, the first thing a creature that can become a demon or immortal does is break the limit of its lifespan.

Like the commonly seen snake demons and fox spirits in legends, they often cultivate for hundreds of years. In reality, the longest lifespan of a snake is only twenty or thirty years, and a fox is even less than twenty years, only about twelve or thirteen years.

Without breaking the limit of life, what is there to talk about becoming an immortal?

If this rule is applied to humans, the saying that a lifespan of over five hundred may lead to immortality can be established.

For ordinary people, a lifespan exceeding one hundred and fifty years is as rare as a phoenix feather or unicorn horn, let alone five hundred years.

However, for a Jie Ming Ren, it is not impossible to exceed five hundred years by constantly borrowing lifespans.

Yu Wusheng said, "The meaning of the existence of Jie Ming Ren is to enter the Heavenly Prison, assassinate the Heavenly Soul leaders, and stop the great calamity of the human world."

"Someone has calculated that in order to pass through the years of life loss between the Heavenly Prison and Liangjie Mountain, at least five hundred years of lifespan are required."

"This critical point of five hundred years made the underworld hesitate. The underworld was afraid that after the Jie Ming Ren obtained enough lifespan, they would suddenly disappear, hide somewhere, and become immortals."

"In this way, everything the underworld has done would not only be meaningless, but would also breed a group of immortal and extraordinary people, causing a crisis in the Yang world."

I immediately understood what the so-called "crisis" meant.

The cultivators who can become Jie Ming Ren are all top experts in the art world. As long as they are alive, they will continue to cultivate. After a hundred years of cultivation, no one can say what level their cultivation can reach.

Since they can hide and cultivate, they can reappear in the Jianghu (martial world) at some point with an invincible posture.

When a person's strength reaches a level of unrestrained freedom and desire cannot be suppressed, it can indeed be considered a crisis for the human world.

I looked at Yu Wusheng and said, "So? The underworld and the dynasty joined forces to eliminate a group of Jie Ming Ren?"

Yu Wusheng nodded, "Yes! This iron prison is the final destination left by the dynasty and the underworld for that group of Jie Ming Ren."

Hearing this, I glanced at Ye Yang, who transmitted his voice to me, "The refining technique of the Zhenmo Tower does indeed have traces of the underworld's involvement."
