I picked up skill fragments in the demon world.

Chapter 907 Ancestors
"It seems that in the mortal world, a family surnamed Zhang was established, and that family's incense has continued to this day, and it can still provide incense offerings," the innate mosquito said.

Upon hearing this, Zhang Chen fell silent, his eyes fixed on the Mosquito Taoist opposite him: "Does the true spirit of the Black Impermanence still exist?"

“This fellow is also a Great Luo Realm being, and his true spirit still exists. It won’t be easy to refine him. Fortunately, I am quite capable, otherwise I might not have been able to suppress him,” said Mosquito Daoist.

Upon hearing this, Zhang Chen's mind raced with various thoughts. Without a doubt, the black-robed monster was an ancestor of the Zhang family. He had only survived by transforming into the river god of the River of Oblivion. However, after being tormented by the Mosquito Taoist, he was probably more than half dead.

Although the other party was his ancestor, Zhang Chen had no good feelings towards him. After all, the other party had previously tried to kill him. If it weren't for the help of the innate mosquito, he would have already fallen victim to the other party's scheme.

However, if the black-robed monster is an ancestor of the Zhang family, he must have clues to the Book of Life and Death. If I can suppress him, I may be able to find the Book of Life and Death quickly.

He didn't care about the life or death of Hei Wuchang, but Zhang Chen couldn't miss the Book of Life and Death, an eleventh-tier treasure, since it was related to his plans in the mortal world.

The underworld is too vast, no smaller than the mortal world. If one were to rely solely on oneself to search for the Book of Life and Death, it would be as difficult as ascending to heaven, like finding a needle in a haystack. However, if the true spirit of Black Impermanence were present, finding the Book of Life and Death would be much easier.

"Release his true spirit," Zhang Chen commanded the innate mosquito.

Upon hearing this, the innate mosquito hesitated slightly: "This fellow is very troublesome. I can only suppress him by relying on the strength of my physical body. Once his true spirit leaves my body, I won't be able to stop him if he tries to escape."

"It's alright, I naturally have ways to subdue him." Zhang Chen smiled smugly upon hearing this. He was least afraid of souls. No matter how strong the Black Impermanence was, what difference did it make if he was stronger than the true spirit of the Queen Mother of the West?

Seeing Zhang Chen's insistence on going his own way, the innate mosquito no longer hesitated. The next moment, a black stream of light shot out from his body. However, before the stream of light could fly away, Zhang Chen's Soul-Hooking and Soul-Seizing skill was activated. Then, the sound of chains was heard in the void, directly binding the black stream of light to the spot. The black stream of light twisted and turned into the shape of a black-robed man.

The man in black robes glared at Zhang Chen, his eyes flashing with fury: "Boy, what kind of tricks do you have to imprison your ancestor like this? If you hadn't sucked Mosquito Daoist's blood and awakened him, I wouldn't be in such a passive position. Today I'll teach you a lesson!"

Black Impermanence lunged at Zhang Chen, attempting to possess him, but Zhang Chen held onto Black Impermanence's chains, so how could he succeed?
The Black Impermanence figure flickered and passed directly through Zhang Chen's body, but it couldn't catch him even a fraction of its size.

"How could this be?" Black Impermanence froze, standing there staring at Zhang Chen in horror, as if he had seen some terrifying being.

“Ancestor, we meet again. I rescued you from the body of Mosquito Taoist. Instead of thanking me, you killed me and showed no gratitude.” Zhang Chen asked.

Upon hearing Zhang Chen's words, Black Impermanence gritted his teeth and said, "I thank you for eight generations of your ancestors! If it weren't for you, you troublemaker, I would have already succeeded in possessing the body. How could I have ended up like this today?"

Zhang Chen looked at the glaring Black Impermanence and shook his head: "Your Excellency is ungrateful and truly disappointing. I have something to ask you now. If you can answer to my satisfaction, I can let you go and give you a way out. If you cannot satisfy me, I will have Mosquito Taoist devour you and make you disappear from the world forever."

Hei Wuchang fell silent upon hearing this, his eyes fixed on Zhang Chen. The situation was beyond his control; what could he do?
"I want to ask the Ancestor, where is the Book of Life and Death? As long as the Ancestor hands over the Book of Life and Death to me, all our grudges will be wiped away, and you can continue to be the God of the Underworld. If you don't hand it over, don't blame me for being ruthless," Zhang Chen said.

Upon hearing Zhang Chen's words, Black Impermanence's expression changed: "What Book of Life and Death? I don't know anything about it. You've got the wrong person!"

"Mosquito Taoist." Zhang Chen ignored Black Impermanence and addressed Mosquito Taoist instead.

“I’m here.” Mosquito Taoist’s eyes lit up.

"Swallow it." Zhang Chen summoned the mouthparts of the innate mosquito and casually tossed it to the Mosquito Daoist.

"Yes, sir!" Mosquito Taoist's eyes lit up immediately upon hearing this. If he could swallow Black Impermanence, it would be a great tonic for him.

The mouthparts of the innate mosquito flew into the body of the Mosquito Daoist and instantly connected with him. Then, the Mosquito Daoist looked at Black Impermanence with excitement. Upon seeing this, Black Impermanence hurriedly said, "Wait a minute, let's talk things out. Why make such a fuss?"

"Either hand over the Book of Life and Death, or die now. Of course, if you think you can escape from my grasp, then so be it," Zhang Chen said.

Black Impermanence lowered his head to look at the chains that were growing into his true spirit. What else could he say?

If he could run, he would have run away long ago. Why would he stay here and waste his breath talking to Zhang Chen? "Activating the Book of Life and Death requires a living being to sacrifice their lifespan. You have not yet achieved immortality and your lifespan is limited. Giving you the Book of Life and Death would only harm you." Black Impermanence looked at Zhang Chen with a reluctant expression, trying to persuade Zhang Chen to give up the power of the Book of Life and Death.

Zhang Chen chuckled softly upon hearing this: "Mosquito Taoist, aren't you going to make a move?"

"Wait, it's just the Book of Life and Death. Here you go. But you don't listen to the elders, and you'll suffer the consequences sooner or later." Black Impermanence took a deep breath, and with a grab of his palm towards the River of Oblivion below, the water churned, and an ancient-looking book appeared before him.

Black Impermanence grabbed the Book of Life and Death, and the next moment his expression changed, looking at Zhang Chen with disbelief: "You are my descendant!"

The moment he grasped the Book of Life and Death in his hand, he already knew the information contained within it.

"I am indeed a member of the Zhang family in the mortal world," Zhang Chen did not deny.

Black Impermanence's face darkened: "Boy, I am your ancestor, and this is how you treat your ancestor? You've completely reversed the Heavenly Gang!"

Upon hearing this, Zhang Chen glanced at Black Impermanence and asked, "And then?"

“You are still in the path of immortality, and your name is still in the Book of Life and Death. Do you know that with just a little manipulation, I can make you die when your lifespan is exhausted?” Black Impermanence looked at Zhang Chen and said earnestly, “If you and I stop fighting and make peace, and you help me possess the body of the innate mosquito, I will make you the head of the Zhang family and grant you immortality and eternal life.”

Upon hearing this, the innate mosquito immediately bristled, its eyes fixed on the Black Impermanence with a fierce glint in them. Then it turned to look at the expressionless Zhang Chen, wondering if it had become an outsider now.
"Don't listen to his nonsense! He created the Zhang family just to collect incense offerings. From ancient times to the present, countless millennia have passed, and their descendants have multiplied endlessly. To him, you are nothing but a stranger. If you really want to acknowledge your ancestors, you are courting death. If he devours me, he will definitely not let you go. Do you think he will let you go after you have wronged him so badly?" Mosquito Taoist hurriedly said.

"For us immortal beings, offspring are nothing more than dispensable things, insignificant as they are," the innate mosquito hurriedly advised, fearing that Zhang Chen would be misled by the other party.

"What business is it of yours, an outsider, to have us talk? Shut your mouth right now, or I'll have my grandson take you away." Black Impermanence immediately rebuked Mosquito Taoist for his attempts to sow discord.

At this moment, Zhang Chen looked at Black Impermanence, a smile appearing on his lips: "Ancestor, I am your grandson. You are already half-buried in the ground. What use is the Book of Life and Death to you? Why not hand it over to me? I am your grandson, and I can rightfully inherit everything from you. This Book of Life and Death should belong to me."

“My dear grandson, it’s not that I don’t want to give you the Book of Life and Death, but activating it requires sacrificing one’s lifespan. This treasure is extremely harmful, and I’m afraid you won’t be able to handle it. Although I’m half-buried, I can still preserve it for you for a few more years. It’s not too late to give it to you after I’ve eliminated its drawbacks,” Black Impermanence said with a smile.

Upon hearing this, Zhang Chen's face immediately darkened: "Old man, you really won't hand it over?"

"Hmph! Your name is recorded in the Book of Life and Death. Do you know that I only need to flick my finger to make you die?" Black Impermanence retorted coldly, adopting a threatening stance.

Zhang Chen's face turned cold upon hearing this: "Ancestor, please activate the Book of Life and Death. I want to see if you can take my soul."

Zhang Chen ate countless peaches of immortality and countless elixirs in the Western Kunlun Mountains, and his lifespan was immeasurable. Although he was not an immortal, even the Golden Immortals could not outlive him in terms of lifespan.

Moreover, he now holds the Soul-Stealing Chains, so even if the opponent activates the Book of Life and Death, they cannot harm Zhang Chen.

Black Impermanence looked at Zhang Chen with a cold glint in his eyes: "Fine, since you are so ignorant of your own mortality and want to betray your master, destroy your ancestors, and disobey your elders, I, as your elder, will teach you a lesson today."

Black Impermanence flipped through the Book of Life and Death in his hand, and in an instant came to Zhang Chen's page.

The Mosquito Taoist watched quietly from the side, showing no intention of intervening, merely observing coldly.

"If you make a move and fail to kill me, you'll be the one who dies," Zhang Chen warned as he saw Hei Wuchang about to attack.

"Boy, you haven't attained immortality yet. Although you have some skills, you are still bound by the Book of Life and Death. If you help me refine Mosquito Daoist, all the grudges between us will be wiped clean! Otherwise, I will have no choice but to clean house." Black Impermanence threatened again.
