With Kai Kai's help, Li Shu really found something unusual inside the zombies, and both zombies had it.

Holding two black things stained with black blood that Li Shu picked up with a dagger into a transparent bag, Li Shu's eyes were full of deep thought when he looked at the two little things.

If he hadn't seen it with his own eyes, Li Shu would never have believed that the body of this third-level zombie was actually equipped with a tracker.

And it's also the kind of tracker that will be quickly located at the moment when a third-level zombie dies.

If Kai Kai hadn't foreseen it in advance and directly blocked the surroundings where the zombies were, I'm afraid their location would have been marked by now.

Li Shu had guessed that the third-level zombies did not directly attack the off-road, but to find the survival of the human race, and then pretended that they could not beat it and fled back to report the news.

In this way, they no longer have to work hard to find humans, but can directly serve them in one pot.

It's just that I didn't expect these zombies to have such powerful minds, and they would also plant trackers in the third-level zombies, and they are the kind that will be marked directly when they die!

If she hadn't had Kai Kai as a plug-in, I'm afraid she would have been successfully remembered by other more advanced zombies at this time.

It's no wonder that in the original book, not long after the end of the second rain in the last days, the security base was surrounded by zombies, and even going out became a problem.

Although the manager of the security base at that time became the male captain Chi Yao, and through him, he successfully solved the problem of going out and supplies, but the losses and casualties during that period were immeasurable.

Li Shu frowned, and pinched the two small things hard, and the tracker shattered instantly, making a "zizi" sound, but quickly regained his calm.

Immediately, she directly threw the transparent bag to Su Qi next to her, and then squatted down to dig the crystal nucleus by herself.

After Li Shu dug up the crystal nucleus, he then looked around and found that there was no trace of other zombies, so he went directly to the safety base.

Su Qi was originally curious to look at the tracker that was crushed by Li Shu, but he caught a glimpse of Li Shu walking back, and he hurriedly raised his heels.

The people of the 1st and 2nd teams all stood in two teams at this time, and their eyes kept looking at Su Qi.

Especially when they saw Li Shu find something from those two zombies, everyone didn't dare to smile like just now, for fear that they would be scolded in the next second.

Su Qi just glanced at the people of the 1st and 2nd teams, and ordered, "Clean up the outside." ”

walked back directly, trotting to keep up with Li Shu's footsteps.

The 1st and 2nd teams looked at each other, smiled wryly, and immediately got to work.

Li Shu glanced at Su Qi, who walked to his side, and was a little vigilant: "Captain, these two zombies were fought by myself, and these two crystal nuclei should always be my own!" ”

Su Qi still cared about the crystal nucleus at this time, and hurriedly raised his hand holding the transparent plastic bag, looked at Li Shu and asked, "What is this?" How do you know they have this kind of thing on them? ”

Although he also thought about what the consequences of the zombies escaping before, and also thought about preventing all the zombies from leaving, Li Shu moved faster than him, and he could only watch from the sidelines.

Even when he went down to investigate the two zombies just now, he just wanted to see if they were dead, and he didn't think about finding anything on the zombies at all.

I didn't expect that Li Shu really discovered the things on their bodies, or the things that were implanted in their bodies.

Especially when Li Shu crushed these two little things just now, he saw them all, and these two little things were obviously still working.

If it's something that doesn't work well with the security base, I'm afraid they're ready for a storm.

Li Shu saw that Su Qi didn't remember her crystal nucleus, he breathed a sigh of relief, looked down at the two small black things lying quietly in a transparent plastic bag that were crushed by himself, and said to Su Qi very seriously:

"Captain, although the environment after the end of the world is very harsh, and technology has also retreated, we still have to pay attention to the problems of science and technology, otherwise it will not be enough to survive for a long time by relying on abilities alone."

During this time in the security base, Li Shu also discovered that although the security base was built fairly safely and the weapons were sufficient, they were all ordinary cold weapons, and there were some simple hot weapons, but there was no guarantee of power, and more weapons that could deal with zombies were developed.

The security base is like a temporary resting place formed in a hurry, except for order, there is no progress in the closed existence, it is impossible to survive for a long time.

Just like today, if there is no Kai Kai, I am afraid they can only build a bridge to victory through a long battle through a long battle and many people, as in the original book.

Su Qi lowered his head, and fell into deep thought because of Li Shu's words.

Li Shu didn't continue to speak, and walked back at a faster pace, giving Su Qi enough time to think.

As for those two little things, as long as there are people who understand technology, they will naturally know what they are at a glance, and they don't need her to worry about it.

As soon as Li Shu came in, he saw at a glance that Xiaobao, who was supposed to be on Li Jincheng's side, was hugging Cheng Ziang, who had not seen him for a long time, and the two small buns were full of happiness after the reunion.

There was also a lion cub circling around the two of them, looking very excited.

It's just been a few months, and the little lion castle has grown a lot, and the little one who was originally held in Cheng Ziang's arms is now almost as big as Cheng Ziang.

And Cheng Yu stood beside the two small buns, and his eyes did look in the direction of the gate.

As soon as he saw Li Shu coming in, Cheng Yu's eyes lit up instantly, and he raised his feet and ran towards Li Shu: "Li Shu......"

When he met the old man, Li Shu couldn't help but hook the corners of his mouth: "Captain Cheng, I haven't seen you for a long time......"

Cheng Yu first circled around Li Shu, and was relieved to see that she was the same as before.

"yes, I haven't seen you for a long time, and you didn't know how worried we were about you!"

Li Shu grinned: "There was something wrong at that time, so I had to go first." ”

"But I'm glad to meet you here."

After speaking, Li Shu looked at the few people who got off the off-road vehicle again, and found that they were all people in the security base, but there were only a few people, so he couldn't help but ask:

"After we left, didn't you just go straight here after you got ready? Why are you driving here now? And it's just a few of you......"

Li Shu's eyes were a little heavy, as if he had thought of a possibility, but he didn't accept it.

Seeing Li Shu's appearance, Cheng Yu knew that she must be worried, so she hurriedly explained: "Don't worry, everyone is fine now, especially Aunt Xu and Lu Qiu, they always talk about you, for fear that you will not have a good time outside." ”
