This ancient and mysterious tree hole has undergone great changes in the last accident, the most obvious of which is the addition of two doors to the tree wall. Lu Chen is not blind, of course he will not turn a blind eye to this, he has already tried to find a way to investigate carefully, but there has been no result.

In fact, from ancient times to the present, the "door" is not complicated, and in most cases it is nothing more than a passage entrance connecting the inside and outside. In other words, if there is a door in the wall, if it can be opened, will it lead to somewhere?

Lu Chen didn't know the answer, but he was very curious about it, he carefully checked almost all the places in this tree hole, especially the nearby tree walls of the two doors, but these two doors were sealed by a force of the five elements, the tree walls were blocked, surrounded by green qi, no matter how he tried, these two doors could not be opened.

To be exact, there is no place to open the door.

After the appearance of those two doors, in fact, it was more of a silhouette on the tree wall, although it was clear that the door type, but most of them still became one with the tree wall. To open the door is to break the tree wall here, which is very difficult to do.

But now, in this ancient tree cave that has undergone great changes again, in addition to the expansion of the territory and the revival of the fairy water, one of the two portals hidden in the tree wall is completely revealed.

The door is open and the outline is clear, and there is even a fist-sized circular bulge in the middle, which is just right for the palm of a person's hand to grasp and grasp. Anyone who sees this door will understand that it can be opened.

But the question is, what is behind the door when it is opened?

※※※

The place itself is the seed of the sacred tree, and in the real world the seed is no more than the size of a finger, but there is such a strange little world hidden inside, which shows its magic.

In the same way, it is almost impossible for a very casual and mundane answer to where the door that can appear inside the Divine Tree Seed can lead when it is opened.

Is it a blessed land full of fairy energy, or a mysterious and unpredictable secret realm? Maybe it is a magical place of gold and silver seas, or a fairy home full of treasures?

These are all beautiful conjectures, but is there another possibility, behind that portal, there will actually be something bad, it will be a terrible world, once opened, there will be some kind of unpredictable force that people can't resist in this situation?

To put it simply, after opening the door, will there be an accident, will there be death?

Lu Chen did not dare to rule out this possibility. He stared at the door, hesitating whether to open it.

This kind of speculation and hesitation about the unknown, it feels a little familiar, Lu Chen pondered for a while, and recalled that a few years ago, he and Ah Tu were forced to fall into the dangerous Longchuan in the depths of that dangerous lost land, and hid here at the last moment. From then on, when he and Ah Tu had to venture out after exhausting all the food hidden in the cave, they seemed to be in the same mood as they are now.

No one knows what fate awaits them when they go out, whether it will be life or death, or something more terrible.

However, it is still a little different from then, Lu Chen and Ah Tu had no way out at that time, and they had no choice, but now he can actually not open the door. He could leave here with Ah Tu as if he didn't see anything, and he could even live his life in the real world outside without entering this ancient tree hole in the future.

Everything was expected by him, but opening this door was not.

Lu Chen stood in front of the door, hesitated for a long time, and in the middle he also went up to carefully inspect the door, except for finding that this door seemed to be born on this tree wall, and the material was exactly the same as the surrounding tree walls, there was no other discovery.

The door was closed so tightly that if it wasn't opened, there would be no movement behind it.

Should you open the door or not? In other words, should you take the risk and look at what's behind the door?

Lu Chen still couldn't make up his mind. In fact, if this door was in his original Middle-earth Divine World, even if there was a high possibility of danger behind the door, he would tentatively open it, but the most critical place at the moment was that this was actually the inside of the Divine Tree Seed.

Who would believe that such a small seed can hide such a small world in the body, which is completely contrary to the cognition of everyone in the world, if it were not for the fact that it is in front of him, Lu Chen himself would not believe it.

It is precisely because he knows that this thing is too weird and strange, so Lu Chen regards it as his biggest and deepest secret, and has not leaked it to the outside world for many years. In the same way, the inside of the Divine Tree is so peculiar here, so after opening the door, there will be no accidents, who can guarantee it? Lu Chen even always felt that it was possible that after he opened the mountain gate, a huge wave of water would rush in from outside and engulf this place!

This inexplicable premonition and thoughts of danger were of course influenced by his extremely unpleasant experience in Longchuan, but this possibility could not be completely ruled out.

It's just that...... Everyone's curiosity!

Lu Chen's hand, I don't know when, was still on the handle of the door, the feeling at the entrance was rough and there was a hint of softness unique to grass and trees, he was thoughtful, and suddenly looked back, Ah Tu was standing beside him, looking like a puzzled expression.

Lu Chen thought for a while, beckoned to Ah Tu, and said in a low voice, "There is something behind the door, can you feel it?"

There are a lot of mysteries in this black dog, especially after the evolution and transformation of the holy beast, many times Ah Tu is more sensitive and magical than Lu Chen's own perception, which can be regarded as a casual question of Lu Chen's dead horse as a live horse doctor.

Asked by Lu Chen, Ah Tu didn't shake his head immediately, but glanced at the portal, and then walked over slowly, first sniffing carefully near the door with his nose, and then went all the way up, to the middle of the door, it seemed that he was a little interested in the raised handle on the portal, and looked at it for a while.

Lu Chen frowned and said, "Is there anything wrong with this thing?"

Ah Tu screamed, and suddenly tilted his head, but he opened his mouth and bit the thing.

Lu Chen was taken aback, and just as he was about to stop it, he saw Ah Tu's eyes blazing, and a pair of dog eyes full of ...... Curiosity. Well, it's really the same as people. Then, I saw that Ah Tu's head was crooked, and he actually shook the thing and turned it around directly.

"Smack!"

A soft sound came from the door from nowhere, faint and deep, as if after sleeping for thousands of years and finally waking up, it was struggling and a little tired, opening its eyes to look at the world.

There was a sound coming from the door, "Suo Suo Suo ......", I don't know what the movement was, but it seemed to be a sound coming from behind the door, as if something was knocking on this door, urging, knocking, eager to open this door and come in from the outside world.

The crack in the door opened a little bit, and a deep darkness gently poured in from behind the door.
