The end of the world: My refuge becomes a land of women

After losing the shock of the giant zombie, the zombies that were originally driven away returned to the gymnasium.

It is not advisable to stay here for a long time, so Su Chen took the crystal core first.

When holding the crystal core, a warmth spread from the palm to the whole body, which was very comfortable, making Su Chen almost scream out.

Fortunately, he quickly came to his senses, put the crystal core into the space ring, and then took out the subsonic transmitter.

Facing the zombies rushing towards him, he forced the zombies in front to leave a passage for himself to leave.

Without staying for long, he walked out of the gymnasium.

With the help of the subsonic transmitter, Su Chen walked out of the gymnasium safely.

Back to the chariot, he did not plan to leave this place for the time being.

At this time, there are tens of thousands of zombies gathered inside the gymnasium. If they are all eliminated, this is a very large fortune.

Can get hundreds of thousands of points at a time!

This opportunity to get rich quickly, of course, he will not miss it.

He took the crystal core out of the space ring and looked at it carefully. It looked very beautiful.

He began to call the system in his heart.

He needed the system to answer his inner doubts.

"System!"

"Tell me, how did the crystal core appear, and what is its function?"

"Why are these zombies so fascinated by the crystal core, and why do you spend so many points to reward it?"

Faced with Su Chen's series of questions, the system quickly answered.

[Ding! The crystal core is composed of mysterious substances in the universe. Because of the advent of the doomsday, it began to appear on this planet. ]

[The function of the crystal core is very powerful. It can change the essence and accelerate evolution! ]

[After the zombie gets it, the level can be improved. At present, this crystal core only has an effect on the life of zombies below level 5, and can make the zombie become a level 5 zombie in a short time! ]

[Similar to the primary gene medicine taken by the host]

Su Chen was shocked when he heard this.

I didn't expect that this thing in my hand has such a powerful function. No wonder it is coveted by so many zombies.

Level 5 zombies!

Su Chen estimated that he was probably not a match for level 5 zombies.

It was no wonder that the system offered a point reward of the same price as the primary gene medicine, since it could be compared with the primary gene medicine.

He hurriedly asked:

"Can humans use crystal cores to improve their strength?"

If it could really improve his strength, Su Chen would not hand over the crystal cores to the system to improve his strength.

The system seemed to have discovered Su Chen's thoughts, and the next words disappointed him.

[Humans can also use crystal cores to improve their strength! ]

[Unlike gene medicine, humans using crystal cores is dangerous and will cause great pain. If they insist on not doing it, they will fail. At the least, they will be seriously injured and half dead, and at the worst, they will die on the spot. ]

[Gene medicine is a gene that is more suitable for humans! ]

The end of the world is so unfriendly to humans. It's so miserable that there is something to improve strength, but it's so dangerous!

It also made him give up the idea of ​​using crystal cores.

He would not risk his life to improve his strength.

It is better to accumulate points honestly and buy intermediate gene drugs.

As for why the system needs crystal cores, it did not explain.

Continue to ask:

"Is there no way for humans to safely improve their strength?"

If this continues, as time goes by, the strength of zombies will continue to increase, and humans may really have no hope of survival.

The system was silent for a long time before replying to this question;

[Doomsday is a punishment and tempering for the life of a planet! ]

[Only when entering the next doomsday will humans have the opportunity to improve their strength. At present, they can only choose to do their best to survive. There is hope if they survive! ]

The system's reply to Su Chen this time revealed a lot of information!

Behind the advent of the doomsday, there are unknown secrets.

Among them, "tempering" made Su Chen have many guesses in his mind, but unfortunately they were not very reliable and needed to be confirmed by the system.

But when Su Chen continued to ask, the system no longer paid attention to him.

This made him more certain that the secrets behind it were very far-reaching, and the secrets of the system were likely to be included in it.

Therefore, the system did not continue to explain.

"Forget it!"

After thinking for a long time, Su Chen finally put this doubt in his heart and waited until he became stronger in the future to study it in depth.

At present, what he needs to consider most is how to survive in the doomsday and live better!

According to the system, it is most cost-effective to give the crystal core to the system, and he can get 5,000 points.

Su Chen quickly made a decision.

But he was not in a hurry to give the crystal core to the system now.

After all, he was still calculatingCounting the tens of thousands of zombies in the gymnasium, nothing is easier to attract them than crystal cores.

He thought for a long time about how to eliminate so many zombies at once.

"Got it!"

He didn't expect that he had the ability to do it, but he could use tools!

This place is surrounded by tall buildings, which can be used as tools to deal with zombies.

Not bad!

Su Chen is ready to blow up the building!

Guide the zombies to a certain location, and then use bombs to blow up several tall buildings around!

Blow up the foundation of the tall building, and the collapsed tall building is enough to crush tens of thousands of zombies to death!

There are several difficulties in doing this.

In addition to a large number of bombs, precise calculations are also required.

Where exactly should the bombs be placed in the building? What kind of bombs should be used? How can he escape safely without being implicated?

All of these require a lot of calculations to do!

For others, it takes a lot of time, but for Su Chen it is very simple.

He has Xiao Ai, and no one can compare to artificial intelligence in terms of calculation.

Soon, Xiao Ai arranged a detailed plan for Su Chen.

As long as it follows the plan, Su Chen can kill tens of thousands of zombies!

As for the bombs, Su Chen of course bought them from the system mall.

After a long period of busy work, Su Chen and the help of the robot quickly placed all the bombs in the planned locations.

Next, it is to attract those zombies.

Su Chen immediately took the crystal core to the gymnasium and immediately attracted all the zombies inside.

He ran in front and led the group of zombies into the trap he had made.

After reaching the designated location, Su Chen decisively put the crystal core into the space ring, causing the zombies to instantly lose the target they were chasing, and they all stayed in the trap.

Su Chen did not stop for long and quickly ran towards the safe range.

Then he took out the remote control of the bomb and pressed it.

"Bang, bang, bang!"

Continuous explosions sounded from all directions, and then the surrounding high-rise buildings collapsed towards the middle at the same time.

Tens of thousands of zombies had no ability to resist this horrific disaster and were crushed into pulp on the spot.

As the high-rise building collapsed, countless dust spread everywhere, and the area within a few kilometers was completely covered, and nothing could be seen clearly.

Su Chen had already hidden in a nearby underground parking lot and was not affected at all.

From the moment the building collapsed, the system prompt sound in his ears never stopped.
