The train left, and Chen Yuan and the others soon returned to the Iron Castle.

The next day was the thirtieth day of the Chinese New Year's Eve. This was their first year in the last days.

Many people, happy and sad at the same time.

Happily, after experiencing a catastrophe that almost pushed them to a corner, they finally survived and once again had a stable home. And there are many people who share their illness and can spend the New Year together.

And the sad thing is that most of them have experienced life and death, and this year is destined to be unable to reunite.

But overall, things are looking up.

Early in the morning, the market is still bustling. There are also many people who are rushing to do New Year's goods.

Although some people have bought almost everything before, they still feel that they are missing something after they go back, so they come to visit again.

Some of them were rushed back by other resource points to do New Year's goods. Factories and mines were only suspended yesterday for a holiday, and today all resource points will arrange a unified fleet to send people who need to come back to do New Year's goods. Of course, the people at the hunting ground resource point have already taken the train back from the holiday two days in advance.

Many people are returning to the Iron Castle for the first time and are simply amazed by the changes in the Iron Castle. However, the living conditions there are not bad, but there are not so many lively places. Even in terms of housing, it is more relaxed, and most people live in single or double rooms. Unlike the Iron Castle, the rate of house construction has not always kept pace with the population increase. As a result, most people still live in collective dormitories. So if they really want these resource points to come back to work in Steelkeeping, they won't be happy.

Others were merchants who came to do business in other nearby settlements. The Steel Citadel is one of the largest survivor settlements in the vicinity, so you can sell your goods here, and you can get a lot of things that other settlements don't have. There are great business opportunities.

And the Iron Castle is not forbidden for outsiders to enter, people who come to the Steel Castle for the first time only need to make a temporary identity registration and leave a fingerprint record to enter the city. So I'm not afraid that after these people commit something in the Steel Castle, they will change their faces and enter the city with a new identity next time.

Of course, there are also those who just join in the fun.

The variety of goods here is really dazzling. Grains, vegetables, frozen fruits, meat, clothing, household items, cleaning supplies, toys, and even firecrackers and fireworks for the New Year. Almost as in the past, there is a wide variety.

However, fireworks and firecrackers are estimated to only be set off in the Steel Castle. Fireworks and firecrackers are set off in other places, which is uncomfortable to find. The zombies surrounding the neighborhood can teach you to be low-key in the last days in minutes.

Today is the Chinese New Year's Eve, and it is almost two o'clock in the afternoon in the market, and the shops have begun to close their doors one after another.

In the evening, every house starts to be lit up, and people start setting off firecrackers and fireworks one after another.

In order to bring out the strong flavor of the New Year, dilute everyone's sadness, and boost the morale of the coming year, the Steel Castle does not prohibit fireworks and firecrackers. After all, there is a 25-kilometer safety zone, and the light and sound of fireworks cannot be transmitted from such a distance, let alone firecrackers.

However, for the sake of safety, the personnel of the Military Intelligence Agency and the city defense force have to work overtime.

The Military Intelligence Agency has placed a ring of cameras on the border of the security zone within 25 kilometers of the Iron Fort, and there are special personnel responsible for monitoring it 24 hours a day for early warning. If a problem is found, the city defense force will immediately announce the cessation of fireworks with a radio announcement.

However, the 25-kilometre safety zone proved to be quite reliable. Although the steel castle sounded gongs and drums and the sound of firecrackers on Chinese New Year's Eve, they were not discovered and disturbed by the zombies 25 kilometers away.

Chen Yuan and the others also had a Chinese New Year's Eve meal at their own home. Of course, it was not only Chen Yuan and his family who ate together, but more than a dozen senior leaders from the settlement, including Liu Jinlong and Wei Chen, were invited to his home for a Chinese New Year's Eve dinner.

That night, Liu Jinlong, Wei Chen, and Luo Youcheng were drunk. Not only to lament the year's encounters, but also to celebrate that they have finally established themselves in the end times.

Even Jiang Wenli drank too much, but after drinking too much, she began to burst into tears and said a lot of nonsense at Chen Yuan.

To the effect that he was late in saving her, why didn't he pass by that damn, hellish mall a few days earlier. After speaking, she simply hugged Chen Yuan and cried in the dark. This is the only time she has shown her vulnerable side in almost half a year. But the next day, Jiang Wenli didn't admit it.

Then she was simply drunk and unconscious, so Wu Qingfang left her to sleep with her that night to facilitate her care. Because her guard class is also on vacation for the New Year.

On the evening of the second day of the first lunar month, the train to the Shenwuguan settlement returned. In addition to Zhang Fatzi and more than a dozen experts in viruses and mechanics who arrived in the first batch, even Qin Mengyao also came back together.

"Why did you come here so quickly, didn't you let you rest at home for a few more days, and come over after the New Year?" When picking up the train at the station, Chen Yuan looked at Qin Mengyao and said.

Qin Mengyao stroked the green silk in front of her forehead, and said disapprovingly: "At this time, it's already good to be able to go home for the New Year." How can there be so much time to rest, experts are in a hurry to come, hoping to develop a therapeutic agent for various enhanced viruses, a follow-up intelligent spider robot for auxiliary combat and an external skeleton as soon as possible. How can I rest on my own. ”

Therapeutic agents for enhanced viruses and follow-up intelligent spider robots and exoskeletons for auxiliary combat are the first batch of scientific research projects that Steelcastle and Shenwu City are preparing to jointly develop.

Needless to say, on the side of the Iron Castle, Dr. Hu has already focused his main energy on this after developing a treatment agent against the ordinary zombie virus, and has made some progress. Now that other virus experts have joined, it is natural to be strengthened.

As for the follow-up intelligent spider robot and external skeleton for auxiliary combat, it is the main direction of the equipment research and development department in the recent period after the maintenance team was split into the mechanical maintenance department and the equipment research and development department. Preliminary test samples are already available. It's just that the performance is much worse than what Chen Yuan requires.

The Follow-up Intelligent Spider Robot for Auxiliary Combat is a combat robot about 1.2 meters tall with 6 legs. Chen Yuan's requirements are that the robot should be flexible, able to climb walls, automatically follow the fighters in battle, and have a friend or foe identification system. Equipped with two assault rifles, two front legs can be used as weapons in melee combat, and additional ammunition supplies for fighters.

The external skeleton, which can increase the strength and speed of ordinary people, allows a large number of unreinforced people and even disabled people to fight zombies.

In fact, these two kinds of equipment have been available in the past for a long time, but there is a certain gap with Chen Yuan's requirements, and there is no actual combat. The experts who were sent to Fort Steel to jointly develop the two devices have been working on these in the past.

The reason why Chen Yuan asked the equipment R&D department to study these two types of equipment is not untargeted. Because, the first place where these two kinds of equipment appeared in Huaxia District in the last century was the Northeast City led by Du Ruhai. The results are amazing.

And the scientist who presided over the development of these two devices was also found by Chen Yuan, named Shen Xinghe. In his previous life, he was known as the father of large mechs. Because the large mecha that later became the backbone of mankind against the zombie invasion along with the mutant powerhouse was also the first to be developed by him. The small spider robot and the external skeleton are actually the basis for the development of large mechas.
