The locust tree is located in the center of the living area, with a pavilion and a corridor next to it. Before the end of the world, this place was a good place for students from B University to chat and fall in love in the summer.

But now, this place is covered with dust and no one has been here for a long time.

Only the locust tree in the middle was still standing there, with luxuriant branches and leaves, and it looked like it was not affected at all by the harsh environment of the end of the world.

Ruan Ning had rested for half an hour, which alleviated the weakness left by the treatment. He now felt much better and didn't look as pale as if he would fall down at the slightest gust of wind.

But Gu Yicheng, who was standing by, couldn't help but frown several times when he saw her frail body. He was thinking about how to get her a corresponding crystal core to increase her ability level and thus strengthen her physical fitness.

Under Ruan Ning's treatment, Jiang Jingyang's legs have improved a lot and he can walk without the help of others. Without serious injuries, there is no worry, and the fighting power of the group has greatly increased.

"I've never seen such a big locust tree in my life." Ruan Ning has lived in big cities since she was a child. Not to mention that towering trees like this one with trunks that are several times thicker than her are rare. I'm afraid they can only be seen in the deep mountains and old forests.

I don’t know whether this locust tree was originally so tall and majestic, or it changed after the apocalypse.

But no matter how you look at it, the latter possibility is more likely, Ruan Ning thought.

Xi Chen, a student at B University, had a say in this. He explained, "This locust tree was transplanted from the provincial botanical garden by our school. Even the pavilion we are in now is named after it. However, this locust tree was less than ten years old and not even half the size of the one we see now. It suddenly grew into this shape overnight, one week after the apocalypse."

Jiang Jingyang on the side also echoed a few words. The survivors in the living area had been frightened by the plants that covered the entire living area in recent days. They usually avoided the plants when they saw them, so no one dared to come to the site where the locust tree was.

This was also the first time Jiang Jingyang came to this pavilion after the end of the world.

Even the operation three days ago took everyone nearly half a month to clear a safe route by detouring from the edge.

Thinking of that group of treacherous people, Jiang Jingyang's mood suddenly became bad. After saying some information about the locust tree, he did not continue talking about this topic anymore.

The third-level wood zombie that was wandering around the living area of ​​​​B University has been killed by Gu Yicheng, but the plants growing around it are still as active and troublesome as before, which makes Gu Yicheng verify the guess in his heart.

Although the third-level wood zombie is very dangerous, the real reason why this place has become a purgatory on earth is probably due to the locust tree in front of us.

They suffered a lot of attacks when they came here, but since Ruan Ning and his group came to this pavilion, the vines and zombies that were chasing them behind them all shrank back, as if something here was affecting them and made them dare not approach this place.

The closer the plants are to the tree, the better they grow. It seems that all the nutrients in the living area are absorbed here to support the growth of the plants.

In order to ensure the safety of others, Gu Yicheng asked them to wait at the pavilion, and he walked towards the corridor alone. Although the surroundings were very quiet and there seemed to be no danger at all, he walked at a leisurely pace, but in fact, Gu Yicheng never let down his guard, and the lightning power in his hand was ready to go, as long as there was a little movement, he would take action immediately.

However, until he walked in front of the locust tree, nothing jumped out to attack him.

Everything went smoothly as if it were a dream.

The lush branches and leaves of the locust tree blocked almost all the sunlight, making it particularly dark under the tree. However, Gu Yicheng had excellent night vision and could clearly see what was hidden under the tree.

——There were two corpses.

To be more precise, it should be a man and a woman, two bodies that have been dead for a long time, the bodies are highly decomposed, their trunks are connected together, facing each other, so the faces of the two people are completely invisible. The white roots at the bottom of the locust tree are entangled with the two people, I believe it won't be long before the two bodies will merge with the trunk of the tree.

Suddenly seeing this scene that is comparable to a horror movie, if someone has a weaker psychological endurance, they might be so scared that their legs would go limp on the spot.

Gu Yicheng's eyes were cold and he just frowned, without much fluctuation in his eyes. He took out a long stick from the space and turned it over the bodies of the two people with an expressionless face.

He had just tried to attack the trunk of the locust tree, but with his current third-level lightning ability, he could not cause damage to it, nor could he shake it. Although this locust tree had no offensive power, its defensive ability was the strongest he had ever seen.

Gu Yicheng had no idea what to do with it for the time being, so he turned his attention to the two unusual corpses.

After some searching, he made a significant discovery.

There was nothing special about the male corpse, but the female corpse was special. There was a crystal core in her head, the color was very strange, brown and green intertwined, like earth and wood, Gu Yicheng couldn't tell what kind of crystal core it was.

But the level of this crystal core is actually almost close to the fourth level.

This is also the highest-level crystal core that Gu Yicheng has seen since his rebirth more than a month ago.

The fourth-order crystal core...

Gu Yicheng remembered that the first time he saw a fourth-order crystal core in his previous life was almost half a year after the end of the world.

At that time, he had just been promoted to the fourth level, and led the team to a villa area in the suburbs of the imperial capital to search for supplies, and then encountered a fourth-level speed mutant zombie in that place. The person who was in the same university as him, and had been classmates for four years, and who had been plotting against him in his previous life, showed his ability in this action, so he noticed the existence of this person, and then thought that he was capable and ambitious, and was a good seedling, so he asked him from another team and promoted him from an ordinary team member to deputy captain. What Gu Yicheng didn't expect was that this person's ambition was to drive him out of the position of captain, and then seize the power of the Gu family after his death, and even drugged him for this.

In this life, I don’t know if it’s because of the butterfly effect, but the speed of zombie evolution seems to have been advanced.

Even though there is only a crystal core that is close to the fourth level and has not yet reached the true fourth level, the impact it has brought to Gu Yicheng is not small.

Gu Yicheng pondered for a moment and then put the crystal core away.

After the crystal core was taken away, the two corpses under the tree began to rot at a speed visible to the naked eye. Within just a few minutes, a foul odor began to emanate from the corpses, which smelled extremely unpleasant.

Gu Yicheng had not planned to stay here for long, and getting another crystal core was a pleasant surprise for him. He found Jiang Jingyang and got three third-level crystal cores. It can be said that this trip of B University was quite rewarding.

Gu Yicheng looked up at the towering tree, a trace of indifference and coldness flashed across his eyes. He took out a bucket of gasoline from the space, poured it on the trunk, and placed a lot of incendiary materials around it.

After doing all this, he walked a little further away, lit the lighter, and threw it under the tree.

The fire caught the incendiary material and gasoline and burned quickly.

"Brother, what's going on? Why is there a sudden fire?" Ruan Ning looked in the direction of the locust tree with a puzzled look on his face, and saw a fire rising there that was even bigger than the one when Gu Yichen went to kill the zombies just now.

The moment the fire suddenly appeared, Ruan Ning, Lin Yang and the others who were waiting for Gu Yicheng to return to the pavilion were startled. They thought something had happened to him inside, so they ignored his request and rushed in to save him.

Gu Yicheng narrowed his eyes and explained, "The situation of this locust tree is special. We can't let it continue to grow in this living area. It's better to burn it. The flames will soon burn to the pavilion. We have to hurry and leave here."

"good."

The fire was indeed getting bigger and bigger. Seeing this, everyone didn't waste any more time and quickly trotted out of the pavilion and away from the living area.

In the center of the living area, at the locust tree where the fire started, the flames burned for a while and then tended to get smaller and smaller, in sharp contrast to the situation outside.

All the flowers and plants around the locust tree were burned, and then the fire began to die out slowly. The burned and charred branches of the locust tree began to grow new green branches and leaves again under the emerald green halos rising from the roots.

After Ruan Ning and his friends left the living area, they did not plan to return the same way they came, but instead climbed over the wall near the west gate to leave the school.

The closest gate to the east side of the living area is the south gate of B University. Gu Yicheng planned to go through this side faster.

After all, it was getting dark and we had to leave school as soon as possible. The shorter the distance, the better.

"Oh my god! You actually made it out safely! How did you do it?!"

When Ruan Ning and his eight companions were passing by a teaching building, they encountered a team of about ten people.

This team obviously knew them. However, Ruan Ning didn't recognize who they were at first, but after thinking carefully, he found that they looked familiar.

Isn't this the team that insisted on following them on their way to the living area, and then, after hearing that they were going to the living area to rescue people, they all became scared and shook their heads like wave drums?

This means...you haven't left yet, are you waiting for them?

They must have had it two or three hours after they went in, so they must have been waiting here for so long?
