Duan Fei took a closer look and found that these completely withered tree trunks still had black filaments entangled, but the source was not those black giant cocoons hanging on the trees, but extended from a core place in the forest.

In this way, Duan Fei's curiosity was even stronger, so he continued to walk towards the depths of the forest, and soon saw an even more amazing scene.

At this time, Fei was located in the most central area of the forest, and he could clearly see that there was an extremely empty clearing in the middle of the forest, and an incomparably huge black cocoon was spreading flat on the clearing.

I don't know how many black filaments there are in all directions, and after being entangled, they form black pipes with the thickness of a wrist, just like the blood vessels that deliver nutrients to the black cocoon, and they keep wriggling, as if they are transporting clumps of energy to the black cocoon.

The black giant cocoon that appeared in the open space was much larger than the one hanging on the tree, at least there was a gap of more than ten times, and it looked like a building close to twenty stories high fell to the ground, making Duan Fei as small as an ant in front of the black giant cocoon.

Almost every few dozen breaths, the black giant cocoon beat like a heart, even if it was just such a simple beating sound, listening to Duan Fei's ears, it was like a thunderbolt on a sunny day.

Such a black cocoon doesn't look like the first layer of the Nine Dead Towers at all!

In other words, the Nine Dead Pagoda was originally so incredible, but in the past, so many predecessors and sages had entered here, and they had never encountered such an encounter as Duan Fei.

How long has it been since Duan Fei had just entered the Nine Dead Towers? He actually had such an unusual experience, and I don't know if this is considered that he is quite close to the Nine Dead Towers?

The black giant cocoon in front of him was so weird, Duan Fei didn't want to get too close before he figured out the situation, he frowned and pondered for a moment, then he suddenly took advantage of the situation to sacrifice the Away Fire Sword, and directly swung the sword and slashed it down.

The target that Duan Fei slashed with his sword was a pipe that transmitted energy to the black giant cocoon, and just as the fire flashed, Duan Fei felt a huge shock coming from his hand, and he could barely hold the fire sword.

This kind of energy pipeline is obviously only made of black filaments, how can it be so hard, it is almost like invulnerable, and the anti-shock force is so great, you can imagine how amazing the energy contained in the pipe will be.

I don't know if Duan Fei's actions angered the black giant cocoon, but I saw the pipes scattered on the ground to transport energy, the three closest to Duan Fei, suddenly flew up like a spirit snake, and wound towards Duan Fei.

Duan Fei retreated, first flashing the control range of these energy channels, who knew that while these energy channels were dancing, they were also able to spit out black filaments one by one, just like a spider spinning silk, and continued to wrap towards Duan Fei.

The black filaments spit out were much more flexible than the energy pipes, and Duan Fei almost increased his speed to the extreme, so that he could barely avoid the entanglement of the black filaments, and at the same time, he waved the fire sword in his hand, rolling up a raging sea of fire.

The single black filament was not so indestructible, and after being swept into the flames, it was quickly burned into a wisp of black smoke and disappeared.

However, it is with Duan Fei's strength that he can successfully avoid the entanglement of these black filaments, if he is replaced by an ordinary demon beast, he will definitely be entangled in the black filaments, either becoming the energy absorbed by the black giant cocoon, or turning into a giant cocoon like those demon monkeys in the forest to evolve.

Of course, after the evolution, the giant ape still does not have its own spiritual intelligence like the demon monkey in the forest, that is an uncertain thing, anyway, there is a great chance, all the actions of these giant apes are under the invisible control of the black giant cocoon.

The one-horned rhinoceros herd is rushing towards the forest, and it is likely that it will become the energy absorbed by the black giant cocoon, or it may be like the giant ape, and thus gain the opportunity to evolve.

In short, this black giant cocoon is too weird, it is definitely an existence beyond Duan Fei's imagination!

At this time, the distance that Fei retreated should have exceeded the warning range of the black giant cocoon, and the energy pipeline that was waving was flat to the ground again, and the black giant cocoon was still beating like a heart every dozens of breaths.

Just when Duan Fei felt that all this was so incredible, he felt that the air around him suddenly had an extremely strange fluctuation, but when he looked closely, he didn't find anything around him.

But then the feeling of air flow became more and more obvious, even if Duan Fei couldn't see anything, he could clearly feel that there seemed to be an invisible figure walking around him.

Duan Fei tried to touch the invisible figure, but there was no doubt that whether it was reaching out or outstretching his legs, they all easily penetrated through the air.

But what puzzled Duan Fei was that this invisible image was in turn able to sense Duan Fei, and whenever Duan Fei wanted to touch him, he would naturally make dodging movements, just like Duan Fei was also an invisible figure to him.

What the hell is such a strange feeling?Duan Fei couldn't help but think of what Blood Dongyang had said to him, he had said that where the Nine Dead Towers were located, it was an extremely strange strange space, like countless spaces stacked on top of each other.

If this statement is correct, then could the invisible figure that Duan Fei could feel at this time be in another space in the same position as Duan Fei?

It's like inside the mirror and outside the mirror, it looks relatively identical to each other, but once it's superimposed, what kind of weird feeling does it feel?

After realizing this, Duan Fei couldn't help but have an even bolder idea: maybe the Nine Dead Pagoda was not unique to the Heavenly Demon Sect!

It is very likely that in another world that I don't know how far away, someone can also enter the Nine Dead Tower, everything they see in the Nine Dead Tower is even exactly the same as in front of Duan Fei's eyes, but they are located in different spaces, even if the positions overlap, they don't know the existence of the other party at all.

However, this black giant cocoon at the moment is obviously a strange existence beyond ordinary cognition, and it is also a foreign object in a place like the Nine Dead Tower, which is likely to make the barriers between different spaces no longer so impregnable, which makes Duan Fei able to sense the existence of an invisible figure!
