There was nothing to say all night, but the sound from outside at night made Han Shuang understand that these night demons were not quiet at night, just like animals, and the whole city made continuous noises.

After getting up the next morning, Han Shuang drove out with Robert. Their goal was very simple. The first thing was to find a construction site and look for concrete first. Cement is not difficult to find. In a city in Noda, there are many buildings under construction. There are a lot of cement in these construction sites. Although three years have passed, they are all placed in the warehouse and there is no problem when used.

Then, the construction machinery inside the construction site was directly repaired. It was not difficult to repair these construction machinery. In fact, there were problems with the batteries, etc., so they replaced them, and some of the oil circuits inside were not even washed.

If the engine is damaged, it doesn’t matter. At worst, it’s just a broken one and it’s just a new one.

Using a small excavator, a cement tanker, etc., Han Shuang and the others quickly prepared everything. Robert did not drive these vehicles, but it was not a problem for Han Shuang. In one day, they had already prepared all the materials.

Even a concrete irrigation truck in Han Shuanglian has been found and repaired.

After a day, Robert was in a bad mood, because Han Shuang would drive almost all of his engineering vehicles, and even her physical fitness was much better than Robert! After a whole day, Robert almost broke up, but Han Shuang felt that nothing happened.

Although most of them have machinery, there are some places that they still need to do it themselves.

However, today they did not directly stir the cement because it was enough to repair these machines and prepare the raw materials during this day.

After returning, Robert barely went to the basement to take a look and then went to bed.

Han Shuang naturally followed him down. Some of the research materials inside were nothing to Han Shuang. She recorded all these things in her mind. To be honest, it was not clear whether Han Shuang would take this thing back, but she had to remember all these materials.

If she goes back and has these viruses on her body, she will naturally have to prepare a serum.

When he got up on the third day, Han Shuang followed Robert to the construction site. Soon the concrete mixer truck and concrete irrigation truck drove back directly.

Then Robert went up to the roof, and Han Shuang directly manipulated the concrete irrigation truck to start pouring a layer of concrete on the roof of the house. It didn't have to be too thick, just ten or twenty centimeters thick. He poured the entire roof a layer, and Han Shuang didn't believe it. If the night demon could still buckle it with his hands, then they would be awesome.

Over the whole day, the roof of this building was poured with about twenty centimeters of concrete, and there was no need for vibrating rods or other things. There was air, and it didn't matter, but they were just guarding against manpower.

On the fourth day, Robert said that he needed to recapture a night demon for experiments. Han Shuang naturally did not stop him. Of course, she also had to help. The place Robert was looking for at the beginning was indeed a place under the bridge.

However, Han Shuang directly found a few excuses to let Robert change to another place. This excuse cannot be simple. There is a data scanning module. Han Shuang can easily find many places that are convenient for creating traps.

In just half a day, Han Shuang had already assisted Robert in capturing a night demon. However, when the night demon was captured and opened, Han Shuang was speechless. The newly captured person was actually a female night demon.

However, Han Shuang checked her body and found no mark of the butterfly. After capturing the female Night Demon, he did not find any other rioting Night Demon.

I just don’t know if this female night demon can develop the real serum. According to the movie, the serum should not be only the female night demon can develop it. It can be heard from Robert’s words that the serum should be universal.

However, Han Shuang pretended that she didn't understand these things anyway. She just watched silently and did not participate. Even after catching the female Night Demon, Robert went to study it, while Han Shuang was going to do other things.

It is very simple, add external window guards with steel structures to all windows.

It’s impossible that these night demons can squeeze their bodies through the narrow gap between these window guards, right? Han Shuang chose rebar about two fingers thick, which is just a matter of punching a few eyes and welding.

On the fifth day, Han Shuang installed window guards for all windows. To be honest, when watching the movie, Han Shuang didn't quite understand Robert's choice. First of all, although the window guards made of steel plates on the inside are powerful, sometimes the function may not be as good as the window guards welded from the outside.

After all, if the steel plate constantly hits the window from the outside, if the steel nails surrounding the walls are knocked through by a huge impact force, the steel plate will easily fall off. Especially the steel plate has a large area of ​​force, which is the same as a person hitting the door.

But the steel bar guards outside are different. If the rebar is as thick as two fingers, if the human body hits it, the area of ​​force is small. If it hits it, how much will Ye Demon die? At least it is not that easy to break through, and the explosion shock wave will not affect such guards at all.

At noon, Robert still went to play the radio routinely. On the sixth day, when Han Shuang was carefully cleaning the building next door, Robert, who came back in the afternoon, brought back a woman and a child!

Seeing this woman and the child, Han Shuang narrowed his eyes slightly. To put it this way, if she didn't show up, should Robert go to the square to commit suicide last night? But because of her appearance, Robert did not go to the square last night. Although the mother and daughter went to the square, it was approaching dawn, and Robert did not attract the Night Demon, so naturally there was no Night Demon passing by in the square.

That's why they spent the dawn safely, and waited until Robert went to the square again at noon, and then both of them came back together. At this time, Han Shuang looked at Sam who was following Robert. Sam was still alive now, and in this way, he really changed the situation here.

I just don’t know if the serum on this female night demon will work.

However, Han Shuang didn't care about this. It would work. She would still do what she should do because she didn't have much time left. Based on the original time calculation, the night demon would attack tonight, and the serum should have taken effect today.
