Siheyuan: Grassroots Counterattack

After this incident happened, the nature of it was extremely bad. The Sijiu City was furious that spies from other countries had infiltrated their own country's military region, and they dared to assassinate their own country's top scientists in broad daylight. This was an act of completely disregarding the New China.

This was something that the New China could not tolerate at all, so an order was issued from Sijiucheng to conduct a thorough investigation of the entire army to eliminate all hidden dangers. In this way, a vigorous movement was launched.

As for Li Tianyi, after resting for two days, he was secretly arranged to fly back to Sijiu City.

Li Tianyi had vaguely heard about what happened next. This time, the investigation did find some people whose historical background was unclear or who had various problems, and the state dealt with them immediately.

After this incident, Li Tianyi became even more reclusive and this lasted for three years. It was not until 1975 that Li Tianyi made a breakthrough in his experiment and he chose to end his retreat.

Now that Li's father and mother are both retired, Li Tianyi usually brings the old couple to live in the military area. Here they can see their grandson every day, and there are more and more neighbors around them, so the two will not feel lonely here.

Li Tianyi can also conduct experiments with confidence without having to worry about his parents getting hurt outside.

This time, Li Tianyi finally extracted a high-strength fiber material from a plant in the ocean. Through chemical synthesis, he finally developed a material that is lighter than special steel, but has better toughness and strength than steel. This material can not only be used in exoskeletons, but also can be widely used in aerospace and aircraft manufacturing.

The materials have only just been synthesized and cannot be mass-produced, but this is already good news.

In recent years, the world's technology has been changing with each passing day. Although Xinhua's ties with the world have become increasingly close, the technological blockade against Xinhua has not been relaxed in the slightest. Xinhua can only grope its way forward on its own.

Although Li Tianyi was anxious, he had to take one step at a time and eat one bite at a time. There is no point in being anxious.

After the new material was developed, Li Tianyi immediately reported the good news to his superiors and applied for a large amount of material for further experiments.

The superiors did not hesitate either. After hearing about the advantages of this new material, they realized its importance in national construction.

So a large amount of materials were shipped to the institute, and the researchers there accelerated the research on lithium batteries.

The liquefaction of cloud explosive agents had been solved a year ago, and then Li Tianyi deployed lithium batteries. It was impossible for him to research everything by himself. Firstly, he did not have the time, and secondly, if he researched everything, what would the people in the institute do?

During this period, a lot of things happened in society. More and more people began to seek redress and more and more people returned to their original jobs.

The Shen family also returned to Sijiucheng half a year ago. Due to Li Tianyi's work in recent years, they have no chance to go to the Northeast, but the letters have never stopped, and Uncle Shen has not suffered in the countryside.

This time when he returned to Sijiu City, Uncle Shen had reached retirement age, so he applied for retirement directly. Now he stays at home to accompany his wife and father, or goes out to play chess with his old man. Anyway, he is very comfortable.

In the steel mill, Li Huaide also restrained himself a lot. He could clearly feel the change in the social trend. Thanks to the fact that he had been active near the steel mill over the years and had not gone outside to harm people, even if there was a liquidation, he would not be reached.

Time flies, and two months have passed in the blink of an eye. In Li Tianyi's laboratory, stands a silver-white skeleton more than two meters high. This is an exoskeleton made of new materials. It weighs only 40% of special steel. As long as it is connected to the power supply, it can be worn for experiments.

This kind of exoskeleton can allow soldiers to carry a load of 500 kilograms, and its theoretical range is 100 kilometers. Of course, this needs to be verified in practice.

Now he is waiting for the arrival of lithium batteries. According to the reports of the two groups in the past few days, lithium batteries are close to success.

In order to ensure the strict confidentiality of the exoskeleton, Li Tianyi also set up a self-destruct function in the exoskeleton. If the exoskeleton is not dismantled according to the steps, the exoskeleton will explode. Although this will cause a certain sacrifice of the soldiers, Li Tianyi asked his superiors for instructions, and his superiors believed that this was necessary.

Because of the arrival of Li's father and mother, Xiaoxue also started to go out to work. She went to the military hospital to find a job, which was still her old profession, a nurse. Although she hadn't done it for a few years, she had done it before, so she quickly got the hang of it.

Li Tianyi did not stop this. Xiaoxue was previously pestered by the children and could not go out. She could only do housework at home every day. Li Tianyi also understood this. Now Xiaoxue can do what she likes. Li Tianyi is happy for Xiaoxue.

The days passed one by one, and finally the lithium battery was successfully developed. Li Tianyi directed people to install the battery on the exoskeleton, and then he personally put it on to test the exoskeleton.

Although it looks like he is wearing something heavy like armor, he does not feel the weight at all when he wears it. For a human, a block of iron weighing more than 200 pounds can be lifted by Li Tianyi with just a light lift.

At this moment, loud cheers broke out in the entire workshop. Everyone knew that their efforts over the past few years had not been in vain. They had succeeded. This kind of thing that could only be seen in future technology had now been invented by them.

After Li Tianyi took off the exoskeleton, he immediately asked someone to check the power consumption of the exoskeleton and the wear and tear of its components. Only after a series of data was reported did Li Tianyi feel relieved.

I called my superiors to report the situation. There were many people interested in coming to see the future technology. On the day of the visit, almost all the elders were present.

Witnessed by everyone, a soldier put on an exoskeleton and ran easily while carrying a 300-kilogram load. He also carried nearly 200 kilograms of weapons and ammunition.

While running, the soldiers performed various movements, which were enough to demonstrate the flexibility and lightness of the exoskeleton.

This also shows that this is a magic weapon for single-soldier combat. Just imagine sending a team of 100 people carrying enough supplies deep into the enemy's rear, how much destructive power it would have!

The test was successful. This exoskeleton can be used as a secret weapon of Xinhua. Although there are no large-scale wars among countries in the world today, the requirements for individual combat on the border are getting higher and higher. The weapon developed by Li Tianyi and his team just makes up for the weakness of Xinhua.
