The Demon Locking Tower is divided into ten floors. Xu Ran just entered the tower and was naturally on the tenth floor.

As he observed, he knew why the monsters in this tower were so rare.

I saw an evil spirit with extremely dim light in the air. When it touched the atomized demon-turning water in the air, the spirit body silently turned into a ball of spiritual energy and dissipated.

But this was not over yet, and the scattered spiritual energy was quickly absorbed and disappeared into the tower by the surrounding walls.

Xu Ran's eyes flashed, and Qianli's eyes were activated, but he discovered the mystery of the Demon Locking Tower. He saw a mysterious and complex formation hidden in the wall of the Diamond Rock.

The demon spirit corroded by the demon-turned water all turned into a pure spiritual energy and was absorbed by the formation in the wall. As for where the spiritual energy went, it is naturally self-evident.

Xu Ran couldn't help but be amazed at Shushan's work. He felt very strange in his previous life. The people in Shushan obviously hated the demon clan very much, and they killed demons everywhere, and did not let go of all the little monsters who were harmless in humans and animals or the peerless evil monsters who slaughtered the city and destroyed the village.

But I have rarely seen the captured monsters kill directly with one sword. Instead, on the grounds that God has the virtue of life, they suppressed them in the demon lock tower to show punishment.

Lock the demon tower and seal the demon, transform the demon water and refine the demon, and the formation absorbs the pure spiritual energy left by the demon clan after his death, which is a complete breeding process line.

These demons who were locked in the demon lock tower were all high-yield cows raised by Shushan. They would continuously provide Shushan with abundant spiritual sources. How could they bear to kill Shushan?

But it is no wonder that Shushan can firmly sit in the position of the number one sect in the world of immortal cultivation, and there are almost endless immortal-level masters from generation to generation. Just because of the abundant spiritual energy, it is almost up to the world of gods. How can Shushan not be strong?

Xu Ran shook his head. In the space on the tenth floor of the Demon Locking Tower, there were only a few evil spirits with no intelligence left, so he could only go to the next floor.

The demon lock tower was wider and wider than the other, but he lowered three layers in a row. Except for the fact that the spiritual energy seemed to be slightly more than the tenth floor, he didn't even see a living little demon, which made him notice a hint of unusual meaning.

Even if the demon race in the tower is constantly refined by the demon-turning water, the demon-locking tower should not be so deserted.

But at this moment, Xu Ran's expression moved slightly, but he felt a trace of extremely subtle fluctuations of spiritual energy coming from a broken demon skull on the ground.

He pointed out, the skull on the ground exploded instantly, and a broken bamboo slip rolled out.

"Don't come over, don't come over! Please spare my life, I really have no meat."

I saw a dim light emitted from the bamboo slip, and a trembling voice came from the bamboo slip.

Xu Ran frowned, picked up the bamboo slip, and injected a stream of spiritual energy into it.

I saw a thin and white-bearded and white-haired old man slowly transformed out of it.

"Everything is dead! All are dead!"

But the old ghost man in front of him seemed to be frightened and kept shouting.

A hint of impatient flashed in Xu Ran's eyes, "Pa!" He slapped two slaps.

The old man's soul body was shocked and he was awakened in an instant, and his eyes seemed to have returned to the clarity.

"I'll ask you and answer it! Otherwise I'll eat you!"

Xu Ran had some guesses about the identity of the old man, otherwise he would just swallow the old man's soul body and he would still know the answer.

I saw a hint of fear flashing in the eyes of the old man in the soul body, and he nodded repeatedly.

"First, where have the monsters in the Demon Locking Tower gone?"

"Second, who are you?"

"In order to break free from the seal of the demon lock tower, the Heavenly Demon Emperor and the Heavenly Demon Emperor in the tower swallowed almost all the flesh-filled monsters in the tower. The villain escaped because of his weak magic power and no entity."

The old man shivered all over, and then hurriedly said: "Sir, don't kill me, villains are useful, villains are useful!"

"The villain is a book ghost. When he was alive, he read all the works of the classics, history, and books, and read all the works of various schools of thought. After his death, he attached the spirit to this book. Over the past few hundred years, he has almost learned about countless scriptures in the three realms of heaven, earth, and man. He has discussed the abyss of knowledge and the vastness of knowledge. Even the gods and Buddhas in the heavens may not know more than I do. It will be useful for me to leave me."

"Sure enough, this is the immortal in the book in the Demon Locking Tower."

Xu Ran confirmed his conjecture. The next step he would build temples in the human world and collect the power of faith, but he lacked a subordinate who was versatile in human nature. In this book, there are few things he did not know about in the three realms, but he could stay to deal with various affairs in the human world for him.

But when he thought of the monsters locking the demon tower, they were actually killed by the Heavenly Demon Emperor and the Heavenly Demon Emperor, and most of them were swallowed by the devil. He hated him so much that he could only hope that the Heavenly Demon Emperor and the Heavenly Demon Emperor were strong enough to make up for his losses.

He knew better about the Heavenly Demon Emperor, but he didn't know what the Heavenly Ghost Emperor existed.

Xu Ran took a deep breath and calmed down his mind and said, "From now on, call you the immortal in the book, stay by my side and handle some trivial matters for me."

By the way, I know what kind of existence the Heavenly Demon Emperor existed and what kind of cultivation was it?”

"The immortal in the book, the immortal in the book..." The old man muttered in a low voice as if he was crazy, his eyes became brighter and brighter, but he felt that the name was specially customized for him. He suddenly felt that it was not a bad thing to follow such a master who knew him so well.

He even felt a little respectful to the voice: "Master, the Heavenly Ghost Emperor is the previous emperor of the ghost world, which is longer than the Heavenly Demon Emperor locked up in this demon-locking tower.

But their strength is slightly weaker than that of the Heavenly Demon Emperor. It is only because of the restrictions of the rules of the human world that they can only exert the strength of the peak of the Earth Immortal, so it is not much different."

"Then lead the way and take me to find them both."

A trace of murderous intent flashed in Xu Ran's eyes. The existence of the two celestial immortals was enough for his body to rise to the peak of the earth immortals.

"What...what?" The immortal in the book was shocked and waved his hand quickly and refused, "Master, that Tian Demon Emperor and Tian Ghost Emperor are two celestial immortals!"

Now the two bigwigs, Tian Demon Emperor and Tian Ghost Emperor, searching for alive prey in the several levels under the Demon Lock Tower to replenish their spiritual power. He didn't want to go down and be swallowed alive.

"I know, I said find them immediately, or I will swallow you first."

A trace of coldness flashed in Xu Ran's eyes.

"Yes...master." The immortal in the book nodded quickly. He could see that Xu Ran was not joking, but he couldn't help but complain in his heart, floating in front of him with nervousness, and rushed to the next level with Xu Ran.

Just as Xu Ran and the immortal in Shu walked to the next entrance magic circle.

Suddenly, two violent figures, one black and one gold, rushed out of the magic circle in an instant, and two extremely powerful auras burst out.
