Lu Chen hurried back to the yard, saw the empty room, his face became stiff, it seemed that the figure just now was indeed the young girl Xi.

For a long time, Young Girl Xi had never left him, but now she left without saying hello. Why?

Lu Chen suddenly remembered that when she was in the Palace of the Sword Emperor, a strong death energy erupted from Young Girl Xi. Now that the God of Death Tree in Death Canyon is blooming, and the death energy is spilling out, it is possible that Young Girl Xi is attracted by the same energy. Awakening.

Lu Chen came out of the yard and found the four evils of the retreat. Mei Xiao and the others also appeared. Looking at the black clouds in the sky, it was as if the night was falling, covering the entire Bixiao ancient city. The tumbling black mist surged Extremely terrible energy.

Fortunately, this energy was only floating in the sky. If it swept through the city, then I don't know how many people would be killed because of it. Lu Chen had personally experienced the terrifying rules of death.

Liu Wushuang frowned: "This energy is the resurrection of the death tree."

Liu Wushuang worked as a guard at Zhang's house for a long time, and learned that there is a forbidden area thousands of miles away, called Death Canyon. It is a forbidden area that is surrounded by life all day long, with fog and poison. I don't know how many people died in Death Canyon. I heard that bones piled up like a mountain at the entrance.

Legend has it that there is a sacred tree of death in Death Canyon. Once the tree blooms, it will cause a riot of death energy and drift in all directions.

The sacred tree of death blossoms and bears fruit, and the death fruit it bears has a chance to understand the rules of death after eating it. This is also the reason why everyone went forward and died in Death Canyon.

For most people, there is a Jedi, few people dare to set foot, at least they have to have the supreme cultivation base to dare to step in, the holy king can't enter, they will be deprived of life and death.

"I'll take a look," Lu Chen said, and without waiting for everyone's reaction, he rose into the air and headed towards Death Valley.

Lu Chen felt a little heavy in his heart. He probably guessed that Young Girl Xi was heading to Death Canyon. He went to see if Young Girl Xi would awaken. Not long after, Lu Chen came to the edge of Death Canyon. The entrance was there. Infinite death energy boiled and formed a There are horrible death storms intertwined, and the surrounding is white bones, and there is a gloomy and terrible atmosphere everywhere.

Lu Chen glanced at the sky, and a tornado-like death air flow hit the sky and then drifted around.

And it was precisely because of this airflow that it floated to the ancient city of Bixiao.

It is tens of thousands of miles away from the ancient city of Bixiao, but the death airflow can float so far, and the aura that it emits is still threatening to the Supreme. One can imagine how rich the aura in Death Canyon is.

Lu Chen stood at the edge area, and there was still a trace of air flowing into his body. Lu Chen could feel the slow loss of vitality.

But Lu Chen didn't care about this loss speed. He stepped on his feet and walked towards the entrance. As he reached the entrance, the death energy that entered his body increased. He quickly swallowed his vitality, and Lu Chen immediately ran Nine Bitters. Heavenly power devours death energy.

Pushing the exercise method into it, the resistance suddenly became much stronger.

Lu Chen walked inside and saw a lot of bones. The bones inside were black, and there were no rules in the bones. It is estimated that the death rules here are too terrifying, obliterating other rules in the bones, leaving them alone. The rules of death make the bones black.

Lu Chen kept moving forward for about a hundred miles, and the surrounding area was dark, with only the whistling sound of death storms, besides, there was no life.

Lu Chen felt that he was about to be unable to walk, because the rules of death here were quickly depriving him of vitality, so he had to stop and comprehend the rules of death first. As long as he understood the rules of death, then the death energy would not only harm him, but also benefit.

In this place where there is only one rule, it is good for Lu Chen, because here only one rule can be swallowed, which can speed up the swallowing speed.

Lu Chen took the initiative to absorb it, letting the rules of death enter the body, and the wisps of death energy entered the body, and Lu Chen became weak.

Time passed by, and Lu Chen sat cross-legged here for two months. At this moment, Lu Chen had gray hair and wrinkles, like an old man.

In just two months, Lu Chen went from being in his prime to becoming a late man.

Suddenly one day, the old Lu Chen opened his eyes, his pupils turned into pitch black, like two deep abysses, but it only lasted for a second before returning to normal human pupils.

"Death rules are terrible," Lu Chen muttered to himself, and then took out a large amount of elixir, and directly absorbed the aura to replenish his life force. After an hour, Lu Chen's hair became normal black. The skin has regained its luster and elasticity.

Lu Chen sat cross-legged for two months and deeply felt the horror of the rules of death. Only if he had practiced the Nine Devouring Heavenly Art, he would dare to sit cross-legged and comprehend the rules of death.

After Lu Chen understood the rules of death, then the death energy in the canyon would not be harmful to him. Instead, it would be beneficial to quickly improve the rules of death.

Lu Chen stood up and continued walking, absorbing death energy as he walked.

I don't know how long he has been walking, Lu Chen saw a tall sacred tree. The trunk of the tree needs at least five people to embrace, which is thousands of meters high, covering the sky.

Whether it is the trunk or the leaves, they are all pitch black, but there is a wave of life.

On the tree of death, there are small white flowers blooming.

"The tree of death?" Lu Chen said softly as he looked at the tree in front of him.

"It's not right, although I felt the fluctuation of life, but why didn't I realize," Lu Chen muttered.

It is not the first time that Lu Chen has encountered the sacred tree of the plant family. Similar to the Bodhi tree of the Zhongzhou region, or the flame tree of the Five Elements Sect, both are plant life entities, but they have different rules.

Both the Bodhi tree and the flame tree have life and consciousness, and can be transformed into human forms, and they can cultivate and advance like human beings.

But this sacred tree of death was different, completely unconscious.

As his gaze moved down, Lu Chen found a silver coffin under the Death Tree. The surface of the coffin was surrounded by a faint silver light, flowing like a liquid.

Inside the coffin, there was a wave of life, and there was also a terrifying aura that seemed to exist, which almost didn't suffocate Lu Chen.

"There is someone in the coffin." Lu Chen blinked. There was a coffin under the tree of death, and then his eyelids began to jump wildly, with an ominous premonition.

Next to the silver coffin sits a still young girl with a beautiful and slender back.

That girl... it's not the girl Xi who else.
