Build a doomsday base, starting from the infinite supermarket.

There is a systematic defense resistance here, and the zombies standing outside cannot come in.

Knowing this, it becomes much easier to clean up the zombies outside.

Everyone rested for a while, and when they regained their strength, they stood within the defense range and attacked the zombies outside.

The psychics who possessed the ability to perform long-range attacks were simply overjoyed.

There is no need to waste time dodging the zombies that may rush over at any time, just focus on attacking.

The feeling is not much different from playing games in an Internet cafe before the end of the world.

Only the blue stripes are used, the red stripes do not move at all.

The rest of the psychics who didn't have long-range attack capabilities were not idle either. They quickly crossed the defense line and killed a few zombies.

Then, before the other party can react, quickly turn back.

They can easily cross defensive barriers, but zombies can't.

Chasing them, they crashed into the transparent defense barrier and bounced out with a "bang".

There were about two hundred zombies that attacked the base this time, most of them were level two zombies. There were some level one zombies, but none above level two.

When the battle was over and the inventory was taken, Song Zhi saw the result and felt a little regretful.

"Boss Song, are you worried about how to deal with these bodies?"

Song Ci saw Song Zhi sighing, walked over to her and asked.

"No." Song Zhi shook his head.

Song Ci: "? Why is that?"

This was the defensive battle in which he suffered the least losses, and most of them were level two zombies. If he was lucky, he might be able to harvest a few crystal cores by cleaning up the battlefield.

This is literally like getting a bargain for free.

Why does Boss Song look unhappy?

"Ugh."

Song Zhi sighed deeply, walked to the pile of zombie corpses, squatted down, took out the dagger in his hand, and checked whether there were any crystal cores dropped inside.

"It would be great if there were level 3 zombies among these zombies. That way the chance of them dropping crystal cores would be much higher."

The chance of a third-level zombie dropping a crystal core is several times higher than that of a second-level zombie.

Moreover, the wealth value converted into by the third-level crystal core in the system is more than twice that of the second-level crystal core.

Ah, third-order zombies?

When Song Ci heard this, he looked at Song Zhi in disbelief, as if he had heard something surprising.

If they encounter a third-level zombie, can they really kill it even with this defensive barrier?

The defense capability of a third-level zombie is hundreds of times greater than that of a second-level zombie. They are also conscious and if they sense that there is a barrier here, they might not foolishly keep attacking.

It is not a bad idea to turn around and leave, waiting for an opportunity to act.

If someone else said this, Song Ci might have directly laughed at the other person, thinking that it was a bit too naive.

But the one who said this now was Boss Song.

Boss Song, who can easily build a tall building from flat ground, can also do such mysterious things.

To her, hunting down third-level zombies did not seem to be a fantasy.

"Haha, Boss Song is really courageous, haha."

Song Ci laughed dryly a few times and joined in cleaning up the battlefield.

Song Ci: Well, Boss Song would just think about this kind of thing and just laugh it off.

This time, their luck was pretty good. These more than 200 zombies produced a total of two crystal cores.

They are all second-order.

The two people who found the crystal core did not take it for themselves, but handed it to Song Zhi as soon as possible.

"Boss Song, the crystal core is for you."

"I found one here too. I'm pretty lucky."

Song Zhi looked down at the two crystal cores placed in front of him and was a little surprised.

Song Zhi: "You found this by yourselves, so why don't you just give it to me?"

Song Zhiyuan thought that the actions to defend the base were all carried out spontaneously by these survivors.

Therefore, anything obtained in this battle will belong to them personally, and she will not force them to hand it over.

They were protecting the base, and that alone was enough to move her.

"Of course it's for you, Boss Song."

Yu Jin lowered the crystal core in his hand and handed it forward with a simple smile.

"I have already joined the base. According to the requirements of other bases, all income from outings must be handed in. Although I am not outing now, I think it is most appropriate to give this crystal core to Boss Song."

He found the crystal core, but if it weren't for the base's defense barrier, this crystal core would never have appeared in his hands.

Moreover, he has no special powers, so the crystal core is of no use in his hands.

"Well, didn't Boss Song say before that if we agree, we can join this base? We all agree, so Boss Song, don't refuse this crystal core, just accept it."

The two of them looked sincere, and had no intention of saying anything against their will.

Song Zhi is not a pretentious person.

Since they had made up their minds, she stopped refusing and accepted the two crystal cores.

"Okay, since you guys are saying that, I'll take this crystal core. Thank you for your hard work this time. Go back and have a good rest. In the evening, we will hold a celebration banquet in the restaurant to celebrate."

For the corpses of zombies outside, Song Zhi found a few survivors with space-related abilities and threw them to the bottom of a cliff farther away.

Normally, these things should be burned when they die, but it's raining outside.

Burning it is not realistic, so just throw it farther away.

When Song Zhi returned to the base, the lights in the base were already on.

She went back to her room, packed up, changed her clothes, and when she came out, she found someone waiting at her door.

"you are?"

Song Zhi looked the visitor up and down, but couldn't find any matching information in his memory.
