Lu Chen had never been, not even once, to be able to see the situation in the ancient tree cavity inside the seed without entering the seed of the divine tree.

This had never happened, not even in his dreams. However, on this day, when he lowered his head and looked at his chest, he suddenly found that the flesh and blood on his chest seemed to be blurred, and his gaze passed through the flesh and bones, and he saw the seed of the divine tree buried deep in his heart.

The Divine Tree Seed was still the same as the one he had seen in the barren valley many years ago, but the difference was that it had more than a dozen filamentous tentacles of different lengths and thicknesses, inserted or adsorbed on the inner wall of Lu Chen's ventricle, firmly fixed in the atrium, and even occasionally a faint red could be seen passing through those tentacles, as if sucking blood from the heart into the seed.

And the appearance of these seeds only flashed in front of his eyes, and then Lu Chen's gaze passed through and saw the inside of the seeds, that is, in that strange and strange alien space, in that ancient tree hole.

The situation in the tree cave had not changed in any way with the upside down of the outside world, at least as far as Lu Chen's eyes could see, he did not see any obvious changes. However, the sound echoing in his ears at this moment was not illusory, and he didn't even have time to wonder why such a strange and mysterious scene appeared in front of him, and his attention was drawn to the knock on the door again.

There are "people" knocking on the door.

That door was the one in the ancient tree hole that he had once opened to the endless eerie void. At that moment, Lu Chen stared at the door, only to feel that his heartbeat seemed to stop suddenly.

The knock on the door ...... still not stopped, it was still echoing, and the "people" outside the door seemed to have extra patience, quietly waiting and calling.

That door, why did it suddenly ring, and what could it be outside the door? Lu Chen raised his head with some difficulty, only to find that Tianlan Zhenjun seemed to be engrossed in his own magic spells, and did not notice the strangeness of his place.

Lu Chen had been behind the door once, and that experience was the most terrifying experience in his life, he didn't want to experience it again at all, but no matter what, he would firmly remember what he saw and heard that time in his mind, and there were some things that he couldn't forget if he wanted to.

He remembered very well what he saw, and that time from the endless darkness of the void, he saw an incomparably large shadow, a part of which turned into a branch and came to him. Although there was no explanation and no record, Lu Chen's heart knew that what he saw that time was the Divine Tree.

It was the Divine Tree that came to him for this seed, and he knew very well, but for some reason, in the end, the Divine Tree still left, and nothing changed. And now, things seem to have changed.

Although he was in an inexplicable and even strange state, Lu Chen had a feeling that he could still open that door as long as he wanted to, as he did before.

Open the door and let the "people" behind that door ...... Or something, come in?

No, Lu Chen didn't want to do that at all.

This knock on the door at this time was by no means coincidental and gratuitous, there must have been some reason, and as for the root cause, it is almost self-evident. He looked up at Tianlan Zhenjun, and saw that the green light in front of him was like a tide, the phantom of the divine tree shook violently, the air around him trembled, and there were ripples in circles, and an inexplicable aura began to seep out, as if something was about to descend.

And the abnormality here, especially this powerful aura that suddenly appeared, finally attracted the attention of the giant dragon and the sky giant pupil who were fighting fiercely over there, obviously they smelled some kind of danger signal, and suddenly turned around together and looked at Tianlan Zhenjun.

Lu Chen still stood alone like a forgotten character, but he still clearly heard the sound coming from the depths of his heart, which did not stop, and continued, and he didn't know when it started, the knock on the door began to gradually get louder.

"Smack!"

"Smack!"

"Smack......

From the original short and peaceful, it gradually turned into a heavy and powerful, the door began to vibrate, and every time there was a knock on the door, the door would tremble violently, and even Lu Chen's body shook with it.

The door slammed and shook, and it looked like it was about to be slammed open.

He covered his heart heavily with his hands, and his face turned pale.

Lu Chen didn't know what the Divine Tree Phantom in front of Tianlan True Monarch would usher in, but in his mind, there was a voice that kept echoing, telling him that the most dangerous thing was not there, but the door in his heart.

Behind that door is the most terrifying, terrifying!

He gritted his teeth, and suddenly snorted softly, as if he felt some kind of extreme pain at that moment, but at the same time, there was a sudden flash of dark fire on the edge of his palm, and then the palm of his hand was blurred, passing through his chest, and it was actually mysteriously entering the mysterious ancient tree hole.

Lu Chen didn't even have time to think carefully about what was going on, so he subconsciously used his hand to resist the crumbling door.

The trembling door was supported by the palm of his hand, stabilized instantly, and then stood erect again in the distance in a strong posture. The "thing" outside the door seemed to feel something, and suddenly became furious, and the sound of hitting the door suddenly grew a lot, and the frequency doubled, only to hear the sound of bang, which sounded instantly.

Lu Chen's face turned white and then red, and then pale again, his body seemed to have some kind of serious illness, a cloud of blood surged up and then disappeared, but no matter what, his hand was still pressed on the door.

I don't know how long it took, maybe it was a long time, maybe it was just a short moment, and the thing behind the door seemed to understand something, and suddenly it was still, and there was no more sound.

Lu Chen was still a little incredulous, but after careful observation, he found that it seemed that the danger had passed temporarily. But at the same time, suddenly he heard Tianlan Zhenjun suddenly let out a roar mixed with anger.

He looked up and saw that a large darkness had covered his head. And Tianlan Zhenjun has disappeared at some point, and the illusory shadow of the Divine Tree that was shining in mid-air was grabbed by two giant dragons at the same time, and at the same time, the giant claw also choked the middle of the Divine Tree, and then in a moment, these three terrifying forces broke out at the same time.

The illusion of the sacred tree shattered, and the green light burst into full bloom, and then fell like a sky full of stars, and the stars were scattered and sprinkled.

Lu Chen's heart cramped, and the pain made him want to faint, but he couldn't really fall, because at this time, just when he thought everything was doomed, suddenly, he heard somewhere, no, it seemed to be behind him.

It's not right, it seems to be in his heart......

Somewhere, there was a ...... The sound of the door opening.

Lu Chen's body shook violently, and then slowly, lowered his head, staring at his chest.

The door, still held against him, was closed safely and firmly.

But on the other side, there is another door.

The second door, which had never been opened, that had never been noticed, suddenly, slowly,

opened.
