Doomsday: Unlimited upgrades to the shelter

Chapter 153 Exchange Raw Materials

Before returning to the bedroom, Xie Yannan stopped by the research room. He hadn't seen Zeng Rui's progress for several days, and he didn't know how many pills he had stored. It's just that these pills don't seem to be of much use at the moment. .

Zeng Rui is a very diligent researcher, no matter how big something happened to Bongu, he never went out.He has been doing research in the laboratory, trying to improve the efficacy of the pills to another level.

There are no less than fifty pills stuffed in the refrigerator where the pills are stored. In a few days, if the pills cannot be consumed, a new refrigerator will have to be upgraded to store them.

He paused, not knowing what to do. There is still no clue about the shelter that can provide weapons, and the remaining quarter of the blueprint is completely clueless.

"Grandpa Zeng, has the research progressed in the past few days?"

After all, their medicine is still a bit weak, if they don't hurry up to develop it, even if they do meet the opportunity, the other party may not be able to appreciate their pills.

"Not yet, it's still stagnant."

Zeng Rui shook his head, helpless, and sighed again.

The main reason is that the mechanical equipment and raw materials of the laboratory are subject to many restrictions, which are not as good as those of professional research institutes.

"There are too few things, and it's repeated every time, and it feels like it's useless."

Zeng Rui complained rarely, he frowned and looked at Xie Yannan.

"It would be great if the various equipment here can be improved a bit. After all, these things that are eaten in the mouth still need strict data support."

"Then...are there any other scientific research centers nearby?"

Xie Yannan asked lightly, you must know that there are some things that the system can't provide at all, so you can only rely on him to look outside to see if there are any other scientific research centers, and he can bring things back for his own use.

Not only Zeng Rui's place, but also Ma Wu's place for research is quite lacking, causing the research to stagnate, not because the technology is not in place.

"There is one nearby. There is a small research center next to the Kongcheng Research Institute, but it seems to be occupied by some strange animals. When we were still there in the past, there would always be a small research center. Some weird noises."

As Zeng Rui spoke, a trace of fear flashed across his eyes, and his voice trembled slightly.

"Occasionally, when I look at it, I feel that there are still some things like sparks running around in the room. It looks like the kind of ghost fire that is spreading."

"You have to know that the zombie wave had already started at that time. We called the police, and the police just walked around routinely, and left when they found nothing unusual."

Hearing what Zeng Rui said, although the Kongcheng Research Institute is now in ruins, there should still be good products in the small research center next to it.

If you want your shelter to gradually develop better, the small objects inside must be upgraded together.

However, the system shouldn't be able to store so many things at once, so we can only exchange for raw materials this time, and search for some laboratory supplies next time.

After spending the night without any abnormalities, Xie Yannan turned over and sat up.

Wei Xiaofei got up early to cook.

He tiptoed to the kitchen, wrapped his arms around Wei Xiaofei from the back, placed his chin on the top of Wei Xiaofei's head, and gently kissed the back of her head, "Fei, I have worked hard on you these days, and I have never been with you much."

Xie Yannan was telling the truth, it was indeed because she was a little tired.

But Wei Xiaofei looked gloomy and gently pushed Xie Yannan's hand away. She turned around and looked into his eyes and said word by word, "Brother Nan, have you ever felt that there is always a strange smell in the basement at night, like It’s a woman…like a woman’s perfume.”

This matter has troubled Wei Xiaofei for a long time, she wanted to ask for a long time, but she didn't want to doubt Xie Yannan.

"I also found out, and I don't know what happened. Even if I want to wake up at night, I still sleep hard at that time. It's strange, there is no way to stay awake."

Except for the matter about that woman, Xie Yannan didn't fully confess, he told Wei Xiaofei all other things one by one.

"I believe you, but let's pay more attention to safety."

Although Wei Xiaofei said so, Xie Yannan obviously felt that she was very disappointed.But there are still a lot of things to do today, and there is no time to comfort her, so I can only hug her lightly, and then walk away.

The more Xie Yannan thought about this, the more weird it became. There was nothing in the basement, but from the surveillance, there were things drifting past every night, and there was also the scent of that woman. Even Wei Xiaofei now realized that it was abnormal.It made him feel that the danger seemed to be getting closer.

Xie Yannan took Xiaoxiao out in the octopus.This time I went to that place with a purpose, not as dazed as last time, just followed the system's positioning and arrived soon.

It's still facial recognition.

After entering, the door automatically closed tightly again.

After entering, Xie Yannan glanced at the ground subconsciously, there was still only the footprints left by him and Xiaoxiao on the thick layer of dust on the ground, which meant that no one had traded during the day.

What Xie Yannan wants to do most right now is to replace that bed at home with a Simmons mattress.Although I am using the cotton mattress produced by my own garment factory, it is not as comfortable as Xi Mengxi's jumping ability after all.

But this is just a raw material supply factory, he can only buy some springs and go back to mix and install them.

He walked to the building where steel raw materials were traded and roughly calculated the number of springs needed.

A spring with a diameter of 5 cm, a natural length of 10 cm, and a weight of about 50 grams.

A Simmons with better elasticity needs hundreds of such springs no matter what.

Not only the elasticity must be considered, but also the impact of his and Wei Xiaofei's exercise.

He wandered around the house where the steel materials were made, only to find that there were no finished springs for sale, only iron plates one by one.

A piece of iron plate seems to weigh at least two to three hundred catties. According to the above instructions, you must buy the whole piece together.In this way, 300 catties of soybeans were wasted at once.

But steel is a thing that is better if you have more, and it is always a good thing to save more.

He poured about 300 catties of soybeans into the balance.

One of the steel plates surrounded by laser rays suddenly disappeared.

Xie Yannan picked it up and put it on the other end of the balance. The weight was very similar, so he recycled the steel plate into the system.
