Siheyuan: Grassroots Counterattack

Happy times always pass quickly, and in the blink of an eye it was time to go back to work. Li Tianyi resumed his normal working hours. After arranging his affairs in the mountains, he returned to the city.

This time his experiment did not require him to stay in the mountains all day, because this project was not dangerous and there was no danger before the assembly was completed.

Of course, this doesn't mean that he will ignore the experiments in the mountains. He just gives them some guidance when they encounter something they don't understand.

He will focus his main energy on the city in the future, but this time he did not report to his superiors, because if they knew what he was doing, they would probably stop him.

So what is this project? Li Tianyi thought of the science fiction movies he watched in his previous life, the laser cannons on the spacecraft, and this is what he wants to do.

He already had information on this in his mind, but it was not as fantastic as in science fiction movies. However, if he could figure it out, it would be unique on earth.

Because Li Tianyi needed a lot of materials to build this thing, and he had to make a light particle collection and conversion pump, which took Li Tianyi a long time to figure out. This machine can collect the energy of external light particles and transition from a low-energy state to a high-energy state. The particles in the high-energy state gather together and form a laser beam through the transmitter.

This kind of energy particle has an extremely high temperature. In Li Tianyi's imagination, armored tanks can be easily penetrated and then cause an explosion.

What's more, laser cannons can be launched into outer space. As long as Li Tianyi aims at a satellite in outer space, he can easily shoot it down.

Of course he also needed a high-power telescope, which was a simple thing and he could make it.

The report Li Tianyi gave to his superiors mentioned a new type of high-temperature cannon. This was not considered deceiving the organization. After all, he simply weakened the function of the laser cannon several times and wrote it in the report.

His superiors were very interested in this weapon and allocated 3000 million yuan to him to develop it.

Li Tianyi didn't have time to gather materials, so he asked his superiors for help. He just had to pay the money. His superiors trusted him and knew that Li Tianyi was not short of money. He would not ruin his reputation for a lifetime for this little money.

After Li Tianyi handed over the list of materials to his superior, he began to draw the blueprints. Because of the high temperature of the laser beam, the materials Li Tianyi needed were all special high-temperature resistant steels.

This type of steel has only been developed in recent years and is mainly used in the aerospace field.

So Li Tianyi suddenly needed this kind of steel, and his superiors also needed to make allocation arrangements. After all, the factory's production plan had already been determined, and now various domestic projects were in the start-up stage, and there was a great demand for materials.

In this way, Li Tianyi waited for a whole year before he gathered all the things needed for the experiment. During this year, Li Tianyi also thoroughly understood all the information about laser cannons. If he could only make a laser cannon fixed on a gun mount before, now he can make a laser gun for himself.

Maybe this is the reason why pressure brings motivation. This year, Li Tianyi has gained a lot. It was only then that he realized that he could not rely solely on others for his life safety, he also had to have the ability to protect himself.

So after the materials arrived, he did not make a laser cannon first. Instead, he spent nearly two months making a laser gun for himself. This laser gun has a range of 5 kilometers. As long as the object is hit by the laser beam, it will spontaneously combust.

Moreover, this laser gun does not require Li Tianyi to replenish energy. The laser gun can automatically absorb light particles in the air, whether they are sunlight particles or light particles. The laser gun can automatically compensate for full energy.

Li Tianyi made the laser gun into the style of a watch, so it would not feel out of place when worn on the hand. Moreover, this watch has more than one function. Li Tianyi also installed a radar on the watch. Li Tianyi does not need to aim. As long as the radar locks the target, Li Tianyi presses the switch and the laser can be fired directly at the target.

This watch can be said to be a collection of all of Li Tianyi's wisdom, and the energy source of the watch is a nuclear battery. The research institute in the mountains is still studying the miniaturization of nuclear batteries, while Li Tianyi has already made the nuclear battery the size of a mung bean.

Don't underestimate this battery, it can provide power to the watch for a hundred years.

After making the watch, Li Tianyi sent the guards out and tried it at home. A piece of wood caught fire instantly after being hit by the laser.

Li Tianyi was very satisfied with his masterpiece. Now he didn't have to worry too much about his own safety. He had extraordinary perception. As long as he sensed any malicious intent, he could activate the watch to save himself.

When the guard Xiao Qian came back and saw a piece of burnt wood in the yard, he was very puzzled. He had only been away for half an hour, so how come this thing appeared in the yard?

In the following time, apart from attending his son's wedding, Li Tianyi immersed himself in the research institute.

Sometimes he worked overtime until very late at night and stayed directly in the research institute. His parents and Xiaoxue at home felt that he was too tense during this period and were afraid that Li Tianyi's body could not bear it.

Every time Li Tianyi returned home, Xiaoxue and his parents would advise him to get enough rest and not work so hard as he is not young anymore.

Li Tianyi didn't take it seriously until An An informed the family that Jin Hong was pregnant. Xiao Xue and Li's mother were so happy that they were busy packing things to send to Jin Hong and her family. Li's father was so happy that he was spinning around.

When Li Tianyi returned home, he saw this scene. Xiaoxue hurriedly shared this happy event with her husband, and Li Tianyi was also very happy.

Nowadays, all the children in the family have their own careers. After graduating from graduate school, An An was assigned to work at the Aviation Research Institute. The unit allocated a house, and the couple moved directly there.

Doudou is also interning in the hospital now. He is doing his internship and studying for a master's degree at the same time. Li Tianyi doesn't care about him because he has his own career plan anyway.

In order to celebrate this happy event, Li Tianyi took a day off to accompany Xiaoxue and his parents to An An's home. Jin Hong was shocked to see that her father-in-law came this time. You know, her father-in-law is a very busy man and you can hardly see him at ordinary times. You can only see him at home during holidays or the New Year.

Xiaoxue and Li's mother pulled Jinhong into the house to talk in private, while Li's father, Li Tianyi and An An were talking in the living room.

On this day, they ate at a restaurant downstairs from An An, which was convenient. After the meal, Li Tianyi and the others said goodbye and left, letting An An and Jin Hong go back upstairs to rest.
