The water in the underwater cave is somewhat muddy, probably due to the dust of the explosion.

After Du Fei went down to the cave, he had a strange feeling in his heart.

When it exploded before, the corpse of the Blood Siren also fell in, but now at a glance, not only did it not torment the Protos Life Sphere, but even the corpse of the Blood Siren was not seen. The water in the cave is not fast, and it is impossible to rush too far.

Du Fei took Illya's hand, and then clamped the struggling little demon king under his arm, and sank all the way along the cave.

Illya unleashed a telekinetic screen to isolate the seawater, and the three of them were like they were in a large bubble, floating in the sea. Before coming to Eyre Island, Du Fei prepared oxygen cylinders, which were enough to stay in the sea for more than ten hours.

After sinking for three hundred meters, and finally reaching the bottom of the cave, Du Fei began to look forward.

After only advancing more than ten meters, as far as Du Fei could see, he saw a light blue sphere with golden patterns on it. The orb lay silently at the bottom of the sea, seemingly unusual.

Du Fei was about to go over and pick up the sphere, when at this moment, a tentacle with the thick roots of a bucket suddenly burst out from the front of the cave, which rolled up the sphere and pulled it into the depths of the cave.

Seeing this, Du Fei was shocked, because that tentacle could be recognized at a glance, and it was the tentacle root of the corrupted giant tree.

There is a corrupt giant tree under Eyre Island, and it is only more than 300 meters away from the underground laboratory of the Freemasonry, which is really weird, if you let the people on the island know, I don't know if they will cover their mouths and shout a few times: "0H,......, Wu.!" ”

In fact, it is not difficult to guess that there will definitely be a corrupt giant tree within tens of kilometers of the appearance of a powerful evolution like the Blood Siren near Eyre Island, but Du Fei really didn't expect that this corrupt giant tree was just below Eyre Island.

Due to the protection of Pandora's mysterious force field, the Corrupt Giant Tree's existing detection methods cannot detect the location of the Corrupt Giant Tree at all, and can only rely on vision and perception to determine the location of the Corrupt Giant Tree, which should be the reason why the people on Eyre Island do not know that there is a Corrupt Giant Tree below.

However, Du Fei didn't have the time to sigh at the strength of the Corrupted Giant Tree's concealment ability, and the Protos Sphere had been swept up by the Corrupted Giant Tree's tentacles and dragged into the cave.

However, there was one thing that reassured Du Fei a little, after the sphere was wrapped in tentacles, an energy chain immediately emerged to resist, which showed that the Protos sphere and the corrupted giant tree did not go all the way. The skin of the Corrupted Giant Tree is tough and regenerates rapidly, and it is coiled in circles, and the orb cannot escape the entanglement and drag of its tentacles.

This is the bottom of the sea, and Du Fei is in a state of fatigue, which is not suitable for fighting, but Du Fei still needs to catch up to see the specific situation of this corrupted giant tree, and if he has the opportunity, he can also try to snatch the Protos sphere back.

Yaya also seemed to find that the situation was critical, and no longer struggled, but quietly picked up Du Fei's body, stretching her neck to look into the depths of the cave.

"Brother......" Illya called softly with a frown, and looked up, her face full of worry.

Du Fei smiled and touched her little face and told her not to worry. Then he chased the tentacles of the corrupted giant tree and quietly walked forward.

After advancing more than 100 meters, the dissolution tone, which was originally only the size of a room, gradually began to grow, and after a turn, the cave suddenly opened up into an extremely spacious open space.

In the center of this large space, a giant tree more than 50 meters high and nearly 80 meters wide is rooted in the mud and sand at the bottom of the sea.

There are hundreds of hatching chambers around the Corrupted Giant Tree, large and small, with various mutated sea beasts wriggling inside.

Corrupt Giant Trees can grow not only on land, but also in the sea, but there are some differences in their form. The most basic difference is the hatching creatures, the Corrupt Giant Tree on land mainly hatches a fixed number of creatures, while the sea-based Corrupt Giant Tree is more about capturing marine creatures for hatching and transformation, because the Corrupt Giant Tree can hatch fewer aquatic creatures, and the most common is the one-horned ironclad whale.

In addition, sea-based Corrupt Giant trees develop more slowly than terrestrial Corrupt Giant Trees, because there are fewer marine plants and there is not enough sunlight, so Sea-based Corrupt Giant Trees absorb relatively few nutrients from their plants. However, the Sea-based Corrupt Giant Tree is rarely hit by humans and other Earth creatures, which in turn allows the Sea-based Corrupt Giant Tree to develop at full speed without consuming a lot of energy and nutrients to hatch combat creatures. ,

In addition, the Sea-based Corrupt Giant Tree also has some peculiarities in appearance, the most obvious being that the Sea-based Corrupt Giant Tree will grow kelp-like plants, which are used to photosynthesize and produce nutrients in place of parasitic plants.

With just one glance, Du Fei recognized that this was a corrupt giant tree that was close to maturity in the third stage, in fact, he could probably guess without seeing it.

Because, the Scorpion-tailed Pterodactyl and the Unicorn Ironclad Whale are both level 5 creatures, and they can only hatch from the third-stage Corrupt Giant Tree.

The appearance of the third stage of the corrupted giant tree did not surprise Du Fei, but Du Fei was still shocked because he saw the Blood Siren.

The Blood Siren's brain cells and other important tissue cells were indeed dead, and the Blood Siren seen at this time was indeed lifeless. However, at this time, the Blood Siren was actually rooted in the top of the Corrupt Giant Tree, as if it had grown from the Corrupt Giant Tree in the first place.

At this moment, Du Fei knew why the Blood Siren had mutated into a tree man, obviously the Blood Siren's body had been assimilated by the Corrupted Giant Tree.

Although the Blood Siren is dead, some of the cells in her body are still alive, and she can still survive with the nutrients of the Corrupted Giant Tree. That is, the Blood Siren is dead, but her body is still alive. It's like a vegetative person with a dead brain.

This means that the Corrupted Giant Tree indirectly possesses some of the Blood Siren's abilities, but does not have the wisdom of the Blood Siren. The Corrupted Giant Tree, on the other hand, has no brains at all, and acts like a beast, attacking anything that threatens it without reservation.

Unfortunately, Du Fei found himself in the dangerous range of the Corrupted Giant Tree.

Du Fei's heart tightened, so he pulled the two little girls to escape from the road. It's just that in the middle of the sea, the role of the drunken immortal Mochizuki step has been greatly weakened.

As soon as he turned around, a tentacle root broke through the ground on the wall of the cave in front of him, and it crossed in front of Du Fei, blocking the way.

Du Fei lowered his head and drilled underneath, hollowing out the last source power to control the metal to swim forward, and Illya also released the power of the mind to speed up and escape towards the road from which he came.

The dense tentacles behind him broke through the ground and entwined up, and the entire submarine cave should shake, as if it was about to collapse.

In front of the cave, dozens of tentacle roots were drilled out by monks and monks, and they were about to come out. Completely blocked.

Yaya snorted softly in a nasal voice, and the three of them moved forward more than thirty meters in a swish, broke away from the siege of the tentacles and continued to escape. Level 4 space mobility can already break through seawater and other media for space movement, but the distance is not as far as on land, and the visual distance of the seabed is short, which also affects the movable distance...... ）
