Apocalyptic garbage classification system

Li Yichen didn't even think about it when he heard this. He lowered his head and pressed the thruster button in his hand to the end...

Whoosh!

A huge thrust pushed Li Yichen's body towards the exit in front. At the same time, the light pillar of the trial channel was completely twisted and torn, and the endless darkness completely swallowed the light!

Li Yichen only felt a pain in his calf, and then his whole body crashed into a black hole. Then, he came to a familiar world...

The exit of the trial passage was actually in the air, and it was on the rooftop of a very tall building. After Li Yichen rushed out of the passage, his strength did not decrease. As a group of undead at the entrance looked up in shock, he flew quickly towards the outside of the rooftop.

"Keep pressing to the end! It's going to explode!"

The sound of the system rang in his ears. Li Yichen didn't know what was about to explode, but at least he knew it was not a good thing. He pressed the button hard without relaxing, and adjusted his body hard to fly into the air...

"boom!"

Like a nuclear bomb exploding, a round white ball lit up in the trial tunnel that Li Yichen had just rushed out of, and expanded rapidly. A huge momentum came from behind, causing Li Yichen's body to lose balance instantly.

Li Yichen quickly released the button in his hand, and was immediately hit by the momentum like a ping pong ball, flying diagonally upward...

"System! The trial channel is gone?"

Looking at the city behind that was instantly razed to the ground, Li Yichen asked in shock.

"Nonsense! You want to enter the trial passage without asking me? You are simply seeking death!!"

The system replied angrily.

"What's wrong? Was the explosion in the trial tunnel caused by me entering?"

Li Yichen forced himself to steady his body, then bought a helicopter, got in and pulled the helicopter up, asking in his mind.

"Nonsense! Do you know that you are already a B-level life now? The trial channel of the undead has just been reinforced and has not recovered yet. You don't have the cooperation of the undead. How can the trial channel withstand the life energy in your body? ?”

The system sounded a little angry. After all, if Li Yichen died, it would disappear completely.

"Damn! Fortunately, I'm lucky!"

After Li Yichen heard this, he was also scared. Fortunately, the system reminded him in time and he was able to rush out. Otherwise, he would have been destroyed along with the trial passage!

wrong! The trial passage is destroyed! How do I go back? ?

Li Yichen suddenly remembered something extremely important to him. Although the trial passage was destroyed and the undead should have withdrawn from the trial early, what about him?

How can he go back? Looking around, a huge pit appeared in the trial passage. The buildings around the pit were almost destroyed, and the trial passage disappeared without a trace.

Looking at the familiar starry sky and some familiar letter combinations on the buildings below, Li Yichen knew that he had returned to a planet he was familiar with, but this planet was unfamiliar to him.

When he appeared just now, he was on top of a thousand-meter-high building, and the surrounding buildings were all about the same height. On the planet where Li Yichen came from, there were not so many high-rise buildings!

Therefore, this is the earth, but it is not the earth he is familiar with, and there are no people he is familiar with here! And the trial passage was destroyed, not only could the undead no longer go to the trial place, he could not go back either.

"System! This trial channel is destroyed. Can I return to the previous world?"

Li Yichen quickly confirmed with the system in his mind.

"Well... if you are lucky and can survive until the next trial starts, you might be able to go back!"

The system tried to make its answer not completely disappointing to Li Yichen.

"I go!"

Li Yichen's heart sank. Just as he had guessed, he... seemed to be unable to go back!

"Host! Actually, I have some good news!"

The system then spoke again:

"When you came out of the trial passage just now, I saw a lot of undead around the trial passage, and they were all high-level undead."

"What good news is this?"

Li Yichen was obviously not in high spirits. If he couldn't go back and was trapped here, what would the point of killing the undead be?

"Think about it! If all the high-level undead on this planet die, then you can rule the entire planet from here! Isn't this good news?"

The system said quickly.

"I'm the only human being, so what's the point of ruling the planet?"

Li Yichen replied angrily.

"Not necessarily! Although this planet is occupied by the undead, there may be humans!"

The system said:

"Besides, even if the human race on this planet perishes, there are still a lot of resources! If you collect more and exchange them for space battleships, there is still a way to return to the previous planet!"

"Huh? That's right!"

Li Yichen suddenly became energetic. Although this was not the earth he was on, judging from the buildings below, this planet's technology was very advanced and there would naturally be no shortage of resources. The undead would not consume any resources. In other words, He does have a chance to go back!

Thinking of this, Li Yichen looked down and found that among the remaining buildings, there were many figures flitting towards the deep pit blasted by the trial tunnel. He knew that those must be undead, so he drove the helicopter away this city.

This is the home of the undead, and there must be many high-level undead. Li Yichen didn't expect the previous explosion to kill all the high-level undead, so it's better to leave now!

First check to see if there are any other survivors around, and also collect supplies. If the trial channel is no longer available, then accumulate supplies and find a way to exchange them for a space battleship to see if you can return to the planet you were on before.

This planet was far more prosperous than the one Li Yichen was on. After leaving this city, he only flew for twenty minutes before he saw the next city. Although it was dark here, it had no effect on Li Yichen, who had eagle eyes.

There were many zombies in the city, and Li Yichen could even see the undead. Moreover, the undead seemed to have discovered Li Yichen, and they all looked up at the sky and looked at the helicopter driven by Li Yichen.

Because of the height, Li Yichen was unable to know the levels of the undead, and it was not far from the city where the trial passage was located. It was estimated that there would be many high-level undead, so Li Yichen did not go down, but passed directly through the city...

After flying for nearly an hour, Li Yichen found the next city, so he landed the helicopter on the top of a building...
