In fact, there is no need to remind the research station that Qin Shou has realized that the situation is getting worse after experiencing the mutated cicada incident.

At first, as long as you deal with ordinary zombies, all kinds of biological groups in the world may mutate on a large scale due to zombie viruses, rather than the initial scattered cases. In this way, the next zombie tide, the next zombie tide, the more abundant the zombie groups you face, the more terrifying it is!

In the past, I didn’t have to worry about the ants and cockroaches crawling by my feet. Maybe one day I would suddenly turn into zombies and become extremely terrifying.

Common creatures such as cats and dogs have mutated, and perhaps mutated mice will soon be found.

The number of rats is quite amazing. Once it appears, it will be a group of rats, which will definitely become a disaster!

Although a floating city was built, there were various defenses on the ground, and automatic turrets were also used to defend against corpse tides and eliminate the terrifying corpse groups that appeared on the full moon night. It was not cost-effective to use on these little things and was also a waste.

In order to eliminate the mutant cicada group and consume a large amount of bullets, Qin Shou was already heartbroken. There must be a more stable plan to effectively prevent such disasters from endangering the Qin Dynasty while saving resources.

After all, the survivors of the Qin Dynasty had to work on the ground before successfully building aerial farms, fishing grounds and pastures in the floating city.

He couldn't come up with a particularly good idea, so he convened a relatively high-educated and smart person around him to hold an emergency meeting for special discussions.

Those who participated in the meeting included two people with the highest education, Gan Zhiqiang and Yu Shixiu, as well as some intellectuals around them. In addition, Xia Yong, who is currently the most reliable and trusted by Qin Shou, is the most trusted Xia Yong.

Everyone, led by Qin Shou, discussed for a long time in the conference room of the floating city.

Xia Yong made a suggestion that all survivors of the Qin Dynasty participated together, and carried out a thorough insect-killing and rat-killing operation in every corner of the base, including Piluo Mountain, to find out all the insects and rat nests, and capture them all in advance to prevent future troubles!

As long as all hidden dangers within the base area and lay cement floors everywhere, it can ensure that these snakes, insects, rats and ants disappear completely, and there is no need to worry about a sudden mutation one day, posing a threat to survivors from the inside.

Although the workload is very large, hundreds of survivors in the shelter can be completed in a short time through Qin Shou's system functions.

This suggestion was unanimously agreed by everyone, and Qin Shou was also very happy. It was indeed true to use Xia Yong, a top student.

Yu Shixiu added more to Xia Yong's suggestion, allowing Qin Shou to dig a moat around the base, including the level area, and the larger the range, the better, and the outside can be connected through a suspension bridge. The moat is mixed with clear water and vaccines, and is specially used to defend against mutant snakes, insects, rats and ants, and it also has a certain effect on other zombies.

It was a fantasy to pour the vaccine into the river and let him enter the ocean, but although the moat surrounding the base would waste huge amounts of vaccines, it could barely be able to do it for the Qin Dynasty, which could produce it on its own and the materials were not too difficult to obtain.

Anyway, the survivors of the Qin Dynasty basically would not go out. They had automatic turrets and wall defenses, which were safe enough in normal times. As long as a small number of vaccines were left for backup, they should be able to persist until more vaccines were produced.

It is best to divide the moat into two layers. Pour the vaccine into the innermost layer, dig another layer on the outer side, and pour medicine specifically used to kill snakes, insects, rats and ants into it.

The outside is a layer of defense against unmutated snakes, insects, rats, ants and various insects, which prevents them from entering the Qin Dynasty shelter. The inside is a layer of defense against mutated zombies and various creatures.

Qin Shou accepted it happily. Although he couldn't bear to leave the vaccines that he had finally stocked up, he still gritted his teeth for safety reasons and used them as soon as possible.

On this basis, he attached his own defense and placed wooden thorn traps on the bottom of the two moats and added electric railings to ensure that there were no fish that leaked the net.

On the same day, all survivors of the shelter participated and began to eliminate rats and insects on a large scale within the base. Even if few people see these things on weekdays, they must be found out if they are carpet-style searches and digging pits and digging soil.

The eastern suburbs are in full swing and are divided into two teams by Qin Shou. While destroying snakes, insects, rats and ants, they are using iron tools made by Qin Shou in batches to quickly dig the moat. Xiongshan is also very busy, and even temporarily put aside the task of dealing with Qin Shou.

It turned out that Xiong Yan failed to successfully eliminate Qin Shou for the first time, and the other party did not even show up. He temporarily put aside his plan and returned to Xiongshan.

On the day the Qin Dynasty No. 3 subway was opened, a murder occurred in Xiongshan.

A male survivor died in the shelter and his face was eaten by unknown creatures. The picture was extremely terrifying. This incident caused chaos, and all the survivors were in danger and extremely scared.

Judging from the traces left on the scene, it is obviously not artificial. Although the survivors are under a lot of mental and physical pressure, they will not do such a cruel thing!

In addition, the autopsy results showed that the deceased was infected by the zombie virus. It was impossible for zombies to enter the shelter. It was likely that some small but very dangerous mutant creature was invaded.

Gu Hong attached great importance to it and immediately ordered a thorough investigation.

During the investigation, another survivor was attacked. The person who was attacked this time was lucky, but a piece of meat was bitten from his thigh.

After inquiring, I learned that the mouse attacked him was not aware of where he came out. When I saw him, I rushed over and bit him like crazy.

Gu Hong immediately ordered to search every corner of the shelter and report it immediately when he found a mouse hole.

Currently, only one mouse has appeared, one has died and one has been injured. If it is not treated as soon as possible, more mice will be infected and mutated, which will be a huge disaster!

The mouse was very small and had no idea where it suddenly came out. The first deceased was very unlucky. Before he realized that he had bitten the major artery in the neck, died miserably, and was eaten by the mouse. If others were also attacked while resting, more casualties would be injured.

Almost at the same time, Xiongshan also launched a rat-killing operation.

Fortunately, it was handled early, so I discovered the mouse hole in time and found the mutant mouse.

After paying the price of several people being injured, it was successfully killed.

Gu Hong was not at ease and stepped up his search to ensure that there was no second mutant mouse. Then he ordered all holes within the range to prevent such a thing from happening again.

In addition, we have begun to study strengthening the defense of shelter in response to this matter.

In the following days, I was busy consolidating defense plans and checking for shortcomings and filling in leaks.

The injured should be vaccinated as soon as possible to ensure that the virus in the body is eliminated.

As for those who were unfortunately attacked by a mutant rat and died, with the consent of his family, Gu Hong ordered people to be cremated and buried in the open space in the eastern part of the shelter.
Chapter completed!
