Demon Burial Valley is a very different place, since the death of the black dragon, it is equivalent to no master, and there are no living demonic beasts.

There was silence all around, and even this deathly silence made the birds perched on the branches flutter their wings casually, as if a ghost rose to the sky.

Such an environment is simply isolated from the world, accompanied by dead demonic beasts, and I don't know how the black dragon has lived in the Burial Demon Valley for so many years.

Fortunately, Lin Xi and the others are not ordinary people, they have excellent psychological quality, and they don't care about the environment, so they start searching directly.

The search went well, after all, there were only black dragon activities here, so there were very few traces left here, and Lin Xi and the others were able to quickly finish investigating the movements and continue to search deeply.

However, it was probably because the black dragon's former lair was far away from the location of the ten peaks, and anyway, after a whole day, the group did not find anything suspicious.

A few traces of activity were found, but they were just the traces of ordinary birds that had been here for a short time.

The next day, there was still nothing.

On the third day, the same was true.

But the group did not slack off.

The unicorn lion and the wild Shura were willing to help Lin Xi get the Wood Spirit Sacred Stone, so they didn't have any complaints when they were tired.

As for Lynsey herself, she is even more confident. He felt that as long as the Wood Spirit Sacred Stone remained in this Burial Demon Valley, he would definitely be able to find it.

On the fourth day, nothing was found.

On the fifth day, they found a relatively large activity area, and everyone was happy, because they all judged that this was definitely the place where the black dragon had lived, but after searching this area for a while, nothing extra was found except for a pile of food bones left by the black dragon.

Obviously, this is just one of the habitats of the black dragon.

The black dragon may have more habitats that need to be searched for.

On the sixth day, the group ruled out another trace of activity.

On the seventh day, nothing was found.

It wasn't until the eighth day that the group didn't know what area they had expanded their search to, and finally found traces of a black dragon's activity again.

After all, this is the fourth trace they have found, and apart from the hollow, the remaining two have not found anything, and as for this one, although everyone hopes to have something useful, they do not have much hope.

The area is about 1,000 square meters, including a meadow and many woods, but it is not difficult to explore.

The group dispersed and began to investigate from different directions.

Two hours later, the crowd converged in the center of the area.

And nothing was found.

And for good reason.

The group then prepared to leave the place and continue to look for the next trace of activity.

But Lin Xi said with some doubts: "Qilin Lion, Crazy Shura, have you found any dead trees these days?"

The reason for asking this question is because Lin Xi found a dead tree during the search just now.

"Nope. ”

"I haven't seen it either. ”

The Qilin Lion and the Wild Shura shook their heads at the same time.

Obviously, the Burial Demon Valley has a very good environment for trees to grow, so in the past ten days of searching, they have not found any dead trees, not even dead grass.

"I saw one, and I think this tree is a little weird when you say that, so let's go and see it. Lindsey said.

"Of course you have to go and see, and you can't let go of anything suspicious. The unicorn lion agreed with Linsey.

Led by Linsey, the crowd came to the place where the dead trees were.

It's a mahogany, 50 meters high, and it takes two or three adults to hug it, so it's a big tree.

However, the nearby mahogany, whether it is the other trees, all grow well, one by one, the branches are luxuriant, but only this redwood, the body of the tree is bare, there is not a single leaf!

Moreover, the bark on the trunk was crumpled as if the tree had been dead for years.

This is in stark contrast to the prosperity of the surroundings, and at a glance, people always feel that this dead tree is out of place with its surroundings.

"Dig it up and see what the hell it is. Madly Shura said first, and with that, the black broken knife shot out, and swung a black blade at the bottom of the tree trunk.

The mahogany fell in response.

The thick trunk lay straight on the ground.

The crack in the trunk was hollow, indicating that the mahogany had been dead for a long time.

The group split the trunk of the mahogany along the middle, and found that it was hollow, and there was nothing strange or anything else hidden in the trunk.

"There must be a reason why the mahogany dies for no reason, and since you can't find it from the trunk, look for it from the roots. Crazy Shura said.

Lin Xi didn't hesitate, and directly used the sword of fire origin to start prying the soil and digging the roots.

The soil is soft and the digging is smooth.

But don't look dead to the mahogany, the roots of the trees in the ground are scattered layer by layer, the root system of size is very developed, except for one taproot, the rest of the fibrous roots, there are as many as thousands, and the length of each root is more than one meter long!

"You can't break any of the roots, you have to cut out all the roots. "The unicorn lion was worried that there was something strange about one of the roots, so he asked everyone to clean up all the roots.

First get out the taproot, the taproot is hundreds of meters long, but nothing unusual was found, it was shriveled and already dead.

The rest of the fibrous roots were also dug out one after another, and Lin Xi and the others carefully examined them.

"Look at this one. ”

Half an hour after digging the earth, Mad Shura suddenly said this.

I saw that the fibrous root held in the hand of the mad Shura was not thick, only the thickness of a finger, and the length of the root was only about five meters, but the tip of this fibrous root was still inserted in the soil.

The tip was attached to a black trunk, as if it had been inserted into it. "Asura's tip shaved open the soil, revealing a small black trunk.

"Perhaps, it is the trunk buried in the ground that takes away all the nutrients of this mahogany, so the mahogany will die, but, why is this trunk underground?"

"Dig it up and see. Lindsey said.

So, everyone began to dig into the earth, and gradually, the black trunk gradually revealed its body.

It was actually a terrifying black tree trunk with a diameter of 100 meters!

Just by analyzing the trunk, it is not clear what kind of tree it is.

Moreover, the entire trunk is inclined downward, and its length cannot be estimated.

So, after digging out a section of the trunk, the group dug along the downward terrain and worked for an hour before the trunk was fully exposed.

The trunk is not particularly long, but it is also a hundred and fifty meters away, but compared to the diameter of a hundred meters, it looks like a fat wooden pier.

Moreover, the two tops of the trunk do not look like they have been cut, as if they were born round, and there is not a single root system missing!

Even if the trunk is dead, it should at least have roots, but there are no roots!

"What the hell is this tree?"

After lifting the tree to the clearing, everyone looked at it and was very puzzled.

Not only does it have no roots, but the two apex parts of the tree are cylindrical, the same thickness as the rest of the trunk, and it is not at all like an ordinary tree, which is thick at the bottom and thin at the top.

"It absorbs all the nutrients from the mahogany, so it should be alive, maybe we can't call it a trunk, it's a tree. The unicorn lion said.
