Shen Feng was taken underground by the tree people, only to find that the underground was the enemy's base, and the emptiness of the underground world was far beyond Shen Feng's imagination, because Shen Feng could not see the edge of this underground world at all, Shen Feng guessed that this underground world was a few kilometers in diameter, and the surrounding walls were occupied by tree roots, and in the underground world, hundreds of tree people were constantly moving around, and these tree people were like tireless machines, working all the time.

Shen Feng was grabbed by the vines and thrown into a translucent cage, this cage was made of plants, the whole body was pale green, the surroundings were slimy, and there was a strange smell, which made Shen Feng feel uncomfortable, he felt that this cage that imprisoned him seemed to be too simple, but it was just right for him to escape.

The rest of the living people were also thrown into the cage one by one, and everyone did not resist, because as long as they did not resist, the tree people would not attack, and although everyone was injured now, they still had the ability to act, so everyone was preparing the means to fight back.

As long as they don't struggle, the Treant will assume that their prey is dead, and it's much easier to deal with.

At this time, Shen Feng suddenly found that there seemed to be a lot of cages around, so he couldn't help but push open the lid on the cage and look around, and suddenly, Shen Feng was terrified, there were a lot of branches hanging down above this underground space, and the tails of these branches were cages one by one, and inside many cages, there were prey one by one!

Many pale green cages have a lot of liquid in them, and these people are soaked in the cages, and the flesh and skin on many people's bodies have disappeared, and only the bones and clothes in the cages can be seen, which means that these people have been killed, and the flesh and blood on their bodies have been dissolved by the liquid, and the branches connected to the cages also bulge a bag, which keeps moving towards the top of the branches, as if humans are swallowing food.

Look around, there are humans in the cage, there are also mutated cats and dogs, mutated cats and dogs as big as lions and tigers are locked in the cage to dissolve, some can still see the head, and some have only skeletons left. There are also animals that are cockroaches and mice, even the sparrows flying in the sky have been caught, no matter what the animal is, whether it is alive or dead, all of them have been caught here by the tree people, and the guys in the cage are basically dead.

Shen Feng suddenly remembered a plant, that is, pitcher plants, it seems that pitcher plants are also predated like this, and what pitcher plants can digest is only small insects such as flies and mosquitoes, and now, these people have become flies and mosquitoes, it's not too funny. It is an exaggeration that pitcher plants, which are used as ornamental crops, are caught by humans for food at this time.

In the underground space, there are thousands of these cages, maybe there are more in places that Shen Feng can't see, and among these cages is the food of these tree people today!

Some of the cages became shriveled and the animals seemed to have been digested, when the cages suddenly fell to the ground, revealing the remaining animal bones in the cages.

"I didn't expect that one day, I would also become a food for plants, it's unimaginable." Shen Feng saw the scene in front of him, and the shock in his heart was indescribable, although he had found the enemy's lair, but now at this time, he appeared here as food.

Suddenly, Shen Feng felt an itch on his feet, so he hurriedly looked down, but found that there was already a layer of transparent liquid at the bottom of the cage where he was, Shen Feng hurriedly used the long sword in his hand to stab a hole at the bottom of the cage, and the digestive juice immediately flowed down the hole, and Shen Feng finally avoided the fate of being digested at this time.

The soldiers who came in with Shen Feng also lifted the lid on their heads, and kept gesturing in their hands, the meaning was obvious, that is, there were digestive juices flowing out of their side.

Shen Feng saw that none of the weapons on these people were carrying, thinking that they were thrown away when they were caught before, whether it was a gun or a sword, everyone didn't have it with them. So Shen Feng handed over the Yitian Sword and motioned for these people to stab the cage out of the hole, everyone nodded hurriedly, passed the long sword to each other, and pierced the bottom of the cage out of the hole, so that the digestive juices flowed out to avoid being soaked in the digestive juices.

The treemen walked around and stopped, and did not find any abnormalities, after which more than fifty treemen left the space again, and the remaining fifty treemen continued to walk around in the space, and there were people who were still calling, and when they walked over, they slapped people to death like swatting mosquitoes, and then continued to patrol, killing people or animals who were not dead.

Shen Feng thought about it, it was not a way to continue to stay in the cage, so he carefully got out of the cage, the tree man seemed to have found an abnormality, and walked to Shen Feng's side, Shen Feng suddenly became nervous, if he was swatted to death like a fly, wouldn't it make people laugh out of their big teeth?

Shen Feng suddenly took out his mobile phone, opened the music software, played a majestic song, and then threw it out into the distance, the empty underground world, modern music kept echoing, and more than a dozen tree people nearby were attracted to attention, and they all walked in the direction of the mobile phone, taking this opportunity, Shen Feng climbed up along the branches of the cage.

The other forty-one survivors all looked at Shen Feng with strange eyes, but they didn't expect that the city lord, who had always been chic and strong, actually liked to listen to this kind of song, this kind of song was completely beyond their cognition, and Shen Feng ignored these people, he grabbed the branch with one hand, and kept gesturing with the other, signaling the survivors to stay where they were and wait for him to come back.

After that, Shen Feng climbed carefully along the branches, I have to say that these branches are still very strong, after all, the cage is either loaded with people or mutated animals, if the bearing capacity of the branches is not good, then these cages would have fallen to the ground a long time ago.

The cage told that it was about ten meters away from the ground, and in such a high place, only the tree man could hang everyone together, Shen Feng kept climbing up, climbing a height of about thirty meters, and then came to the top, and looking down from here, you can see most of the area of the underground world, and the tree people who are constantly walking below can also see it.

At this time, Shen Feng's mobile phone had been trampled by the tree man, and when there was no sound coming from the ground, the tree man continued to patrol around.

At this time, at the top of Shen Feng, here are dense pipes, Shen Feng put his ears on it, and then heard the sound of water flowing from the pipes, in this regard, Shen Feng guessed that what flows in these pipes is digestive juice, and the energy contained in the body of the digested animals is dissolved, whether it is carbohydrates or proteins, even if it is fat, all are dissolved, except for the bones that cannot be digested, other body parts are basically digested.

"Where are the liquids in these pipes going?" Shen Feng's heart began to speculate, it stands to reason that these treemen also need energy to act, and energy will not be generated out of thin air, the light in the white mist is very poor, so the treemen are not very photosynthetic to produce energy, that is to say, the treemen must have other ways to obtain energy.

After thinking about it, Shen Feng couldn't figure out where the energy of the treeman's actions came from, so he had to move along the pipe, and finally, Shen Feng came to the center of the underground, he looked up, but found that there was a bright light above his head, and there was a pipe leading to the top, Shen Feng thought about it, and crawled up along this pipe, he wanted to know what was on it.

Shen Feng climbed up two hundred meters and came to the position on the surface, at this time he was surprised to find that there were bomb craters all around, and there was a big tree more than ten meters thick that fell to the ground, and there was a smell of gunpowder smoke left after the explosion around him, Shen Feng only understood at this time that he had gone around and returned to the previous bombing area, which was amazing, but he didn't expect the location of the towering tree before to be directly above the underground world.

In other words, the hollow trunk of the fog-producing tree leads to the underworld, which is responsible for generating the fog and transporting it to the towering tree above.

At this time, although Shen Feng could escape, if the forty-one guys in the underground world were smart, they would also crawl out, and everyone would quietly escape together at that time, however, an extremely bold plan appeared in Shen Feng's mind, since he had figured out the enemy's headquarters, then why not turn this place upside down? Besides, if this place is not dealt with in time, it may continue to expand in the future, and it will definitely threaten more people.

Shen Feng thought of this, looked around, and made a vine tens of meters long, which was left by the tree man who was blown up before, and there was no rope at present, so he could only use the vine general, fortunately, these vines were extremely strong.

Shen Feng returned to the underworld, rescued forty-one survivors using tree vines, and sent them out of the tree hole all the way, Shen Feng instructed in a low voice: "Your soldiers are divided into two ways, ten people leave the fog to find Chu Chaoyan and Yang Chang respectively, let them be ready to respond at any time outside, and the other thirty-one people, go to the vicinity of the highway to find cannonballs, just find dozens of cannonballs, when the time comes, you send the cannonballs to the tree hole, and I will blow up all the caves below to prevent future troubles!" ”

These survivors didn't expect that they would be able to come out alive after being caught by the tree man, and they couldn't worship Shen Feng anymore at the moment, at this time, they all obeyed Shen Feng's orders, and after grouping, they all moved in the predetermined direction, once they found that something was wrong, they immediately fell to the ground and did not move, as long as they were not stepped on by the tree man, there would be no casualties.

At this time, Shen Feng was idle and had nothing to do, and once again explored the path down the tree hole, at this time he was very curious, where did these pipes at the top lead to? With so many digestive juices, at least there's a place to go, right? Thinking of this, Shen Feng moved forward again along the pipeline, and the more he went, the more confused Shen Feng became, as if the pipeline was going down.

At this time, Shen Feng saw a red light appear in the underground world, so he hurriedly approached carefully, and at this time, he suddenly found that many tree people were also approaching this side, and the heads of these tree people were all shriveled, that is to say, these tree tumors would also shrink.

Shen Feng lay on the pipe above and looked at it, and found that at the end of the pipe was a huge ball, and the ball was emitting red light at this time, and this huge ball was the end of the pipe.

"So much digestive juice, is it all absorbed by this ball?" Shen Feng thought so in his heart.

Shen Feng was a little incredulous, the cage in the underground world was tens of thousands, so many digestive juices were all absorbed by a large round ball, which was really too exaggerated, not to mention that this round ball was only one meter in diameter, even if it was loaded, it couldn't hold so many digestive juices.

However, at this time, a tree man approached the ball, and a spike suddenly grew out of the ball, which instantly pierced into the tree man's head, that is, in the tree nodule, Shen Feng was immediately surprised when he saw this scene, he knew how hard the tree tumor was, but the spike actually pierced into it casually, this is also too sharp, right?

Next, the orb poured some liquid into the nodules, and the treeman's head suddenly became full, and then the treeman left the place, as if he had been replenished with energy, and the rest of the treemen approached the ball, and the orb injected liquid into each of them.

Shen Feng understood, "It turns out that the energy of the tree people comes from like this, their heads are the energy of action, and this ball is equivalent to a gas station, the entire underground space is like a whole, the tree people are responsible for catching animals, the animals provide energy to the plants, the energy is transferred to the tree people, and the tree people continue to catch animals." ”

At this moment, the shock in Shen Feng's heart was difficult to add, he thought it was a thoughtless plant, but now it has become a behemoth, not only capturing animals, but also plundering the energy of animals, using these energies to strengthen themselves, except for the lack of intelligence, these plants are simply perfectly functioning machines.

Suddenly, there was a noise at the entrance of the cave in the underground world, and Shen Feng followed the pipe above his head to the vicinity of the cave entrance, and then saw the appearance of more than thirty tree people, all of whom were tied to a large number of people, and these people were the artillery and the guys of the expeditionary force led by Guo Pinming.

Zhou Hai has been abusing since he entered the underground world, from Jin Zijie to Wang Yuesheng, and then scolded these emotionless tree people, and in the end, he was put in a cage, and the tree man put his hands together and slapped Zhou Hai to death in the cage, Shen Feng closed his eyes a little unbearably.

Shen Feng also saw Guo Pinming, who was already unconscious, his body was full of steel armor, and he was thrown into the cage motionless at this time, even Jin Zijue had been caught, Jin Zijue was also in a coma at this time, he was slapped by the tree man, and dozens of bones on his body were broken at this time, and now he can or is fortunate that he is a third-order ability, and his physical fitness is better than that of ordinary people.

Shen Feng didn't meet many treemen here, that was because most of the treemen were attracted to the side of the road, so the casualties on the side of the road could only be described as tragic, no one escaped from the attack of the treemen, everyone was captured, and the survivors could only bow their eyebrows and pretend to be dead on the treemen. If you don't pretend to be dead, you can't do it, as long as you struggle casually, the vines will be tied more tightly, and in order to avoid being strangled, all the living people are holding their breath and concentrating, and they don't dare to make too big a movement at all.
