Chapter 686: The Dead Branches Turn Into Ancient Trees

"Yes..." Li Fan frowned slightly, as if he was trying to recall.

Ximen Yu stared at him intently and listened attentively.

"I can't remember." After a long time, Li Fan shrugged and said helplessly.

"You..." Ximen Yu's face froze, "How could such a strange thing be easily forgotten?"

He looked at Li Fan with disbelief.

"Fellow Daoist Ximen, why don't you tell me what this dead branch is. Maybe I will remember it while you are talking." Li Fan suggested with a smile.

Ximen Yu narrowed his eyes and swept his eyes back and forth on Li Fan.

Li Fan was not afraid at all, and looked at him calmly.

As if he was unsure of Li Fan's strength, Ximen Yu finally chose not to act rashly.

He turned his body and showed the dead branch behind him again in front of Li Fan.

After a moment of silence, he said, "I don't know the origin of this thing. At that time, my research on the earth veins was at a bottleneck."

"Under the rule of the Ten Thousand Immortals Alliance, the power of the earth veins was firmly locked by the protective array covering the entire territory. It is extremely difficult to call and study without authorization. I tried many methods, but it is still difficult to find a breakthrough. Just when I was about to change the research direction..."

"About two years ago, the power of the earth veins here suddenly rioted. It seems that a disaster of earth veins that could destroy a state occurred thousands of miles away. It caused a chain reaction. I was overjoyed to see this, and of course I seized this rare opportunity to absorb the overflowing power of the earth veins."

"And this dead branch is what I found from the power of the earth veins."

Ximen Yu said slowly, but Li Fan was thoughtful after listening.

"Two years ago, it seems to be the time node of the red flame burning the sea. Is it the influence of Hongxi forcibly extracting the earth veins in order to force out the red flame hidden in the earth veins?"

The Xuanhuang earth veins are connected as one. Although they are thousands of miles apart, they may still affect each other. Previously, there was a sunken island in the sea of ​​clouds. It was affected by the "hundreds of mountains turning into plains" in the distance and emerged from the seabed.

The abnormal movement of the earth veins observed by Ximen Yu here may be the aftermath of the battle with Chi Yan that year.

Li Fan looked at the dead branches that were still gushing out the earth-yellow earth vein power, and asked in confusion: "The power of the earth veins is extremely pure. How could there be dead branches stuck in it? Ordinary trees will be crushed into powder by the strong pressure in the depths of the earth veins for only a few breaths. What is the origin of this dead branch? Not only can it survive in the earth veins for a long time. It can also attract and absorb the imprisoned earth vein power?"

Li Fan looked at Ximen Yu again: "The abnormal movement of the earth veins here must have not been discovered by the Ten Thousand Immortals Alliance. Otherwise, it is related to the safety of the protective formation, and they will definitely send people to solve the hidden dangers here."

Ximen Yu's face changed slightly, but he did not refute.

"This dead branch does have some magical power. It seems to have the same origin as the earth vein, so I extracted some of it on a small scale for research, and it will only be regarded as the normal fluctuation of the earth vein itself."

The dead branch erupted the power of the earth vein, which seemed to be intermittent and contained some rules. At this moment, it gradually weakened, and finally no more earth vein energy flowed out.

Ximen Yu carefully put away the jade bottle.

"From the same origin as the earth vein?" Li Fan savored this sentence carefully.

Ximen Yu took out a stone slab from the storage ring. It seemed to be peeled off from a rock wall somewhere, and the traces were extremely ancient.

The lines were also quite abstract, but the content they depicted could be roughly understood.

Many small dots represent human beings. They worship and live on the earth.

And underground, there is a big upside-down tree growing.

The roots are densely packed, rooted in every corner of the earth.

The crown of the tree goes deep into the ground, reaching the center of the earth.

"This is what I found in a geological fault when I was studying the changes in ancient and modern terrain. It should be left by the ancient mortal tribe."

"It's not just this mural. I have found similar records of ancient people in various places in Xuanhuang Realm."

"I suspect that the so-called earth veins are derived from the roots of this ancient tree. And this dead branch of mine belongs to that ancient tree."

Ximen Yu explained.

"Although the information left by these mortals is extremely simple. And it is seen by mortals, which may not be the whole picture. But precisely because it is something from mortals, we cultivators often ignore it by default. So the records that should have been erased can survive." Ximen Yu said with a sneer.

"Earth vein tree..." Li Fan touched his chin.

"No." Suddenly, he shook his head.

"It is very similar to what I saw in the illusion that year, but it was still a little different at that time." Li Fan said firmly.

Ximen Yu was not surprised. After thinking for a moment, he said, "It's possible that the ancient tree you saw is even older."

"It may be the source of the earth vein tree."

Li Fan was surprised: "Does the earth vein tree also have a source?"

Ximen Yu took out a few black stones from somewhere, crushed them and sprinkled them on the dead branches stuck in the ground. The black powder was quickly absorbed by the dead branches, and it seemed to become more energetic.

"It is said that there was only one mother tree between heaven and earth at the beginning, which controlled the fate of all living things in the world."

"Later, a huge change occurred, and the mother tree suffered a heavy blow. Some branches even fell from it. Falling into the world."

"One of them turned into an ancient earth vein tree."

Ximen Yu looked at the carefully cared dead branches with pity and said slowly.

A gleam of light flashed in Li Fan's eyes: "How did you know about this, Fellow Daoist Ximen? It's really unheard of."

Ximen Yu's eyes were fixed on the dead branch, and he didn't answer.

Li Fan was stunned for a moment, then nodded slightly.

"Ah, after you said that, I seem to remember it. I met that dead branch here."

Li Fan casually drew the terrain of Tianlingzhou and marked a location.

Ximen Yu then retracted his gaze from the dead branch and firmly remembered the location in his mind. Then he erased the map.

"Time has passed. I have returned to the old place several times over the years, but I have never seen that dead tree again. So Fellow Daoist Ximen should not hold too high hopes." Li Fan reminded.

Ximen Yu sneered: "Such a rare thing is of course hard to come by. But I have always had good luck. After I finish my research on the theory of earth veins, I will definitely try my luck."

"Then I wish you success in advance!" Li Fan clasped his fists and was about to leave.

"Daoyou Han Wuyou, right?" Ximen Yu threw a communication talisman over, "I feel that you and I have some fate. Keep this thing, maybe we will meet again in the future."

Li Fan put away the talisman and did not stay any longer.

When his figure disappeared, the door of the cave closed again.

Ximen Yu frowned deeply: "The world is like a tree, which consumes life day and night..."

"Could it still exist in the world?"
