Super Weapon Swap System

The performance of the Black Eagle Helicopter was absolutely the best, but the price was also very high. Qin Guan had reduced the price to five million hawk dollars, which was already acceptable.    

    

Although Qin Guan could use the system to exchange for more gold, however, if he spent a lot of money, he would be like a rich man. That would have a negative impact on the international market, even if he was a rich man. If you go out, you have to become a Grantai, that's how it works.    

    

The price of the Black Eagle helicopters was already very suitable. They could buy a batch of them in China. As for the imitation of the Black Eagle, it would definitely be very difficult. Or... He would start with the A109 helicopter first and develop his own helicopter industry first.    

    

During this period of time, Qin Guan had been busy introducing helicopters. In the blink of an eye, it was already April. After signing the contract with Sikorsky Company to import 50 Black Eagle helicopters, a new piece of good news arrived. The Kidd-class Destroyer had already been driven back!    

    

These four destroyers were the Han Navy's biggest breakthrough in recent years. From the 3000 ton brigade destroyer, they jumped into the ranks of the 10,000 ton destroyer!    

    

Now, the biggest threat to the motherland was the north. Therefore, these four warships would join the Beihai Naval Fleet and their base would be Binhai City.    

    

This was the most important moment for the navy. Qin Guan would definitely join in the fun.    

    

Qin Guan had already been to Binhai City the last time. At that time, Qin Guan had even exchanged the 022 missile speedboat. He did not know how the navy's mapping was going. Now, he could go and take a look.    

    

Oh right, there was also the inertial navigation system! Qin Guan thought of his promise back then. He had actually forgotten about it during this period of time.    

    

The accuracy of the inertial navigation system was very important. Not only did nuclear submarines need it, but also fighter jets and missiles. If there was an advanced laser top, it would definitely greatly increase the country's high-tech level.    

    

Now, it was still using a floating top. There was a difference of magnitude between it and an advanced laser top.    

    

Speaking of domestic navigation systems, the main research and development was 7707. With the help of relevant units, they worked hard for a long time. Finally, they equipped the inertial navigation system for the first missile nuclear submarine, as well as the Starlight navigation system and satellite navigation system to rectify the inertial navigation error.    

    

The leader of the development of the gyro was Prof. Lin.    

    

Prof. Lin, born in 1913, after a prestigious family, was his father. He was the pioneer of the most important revolution in the feudal society. And he... He was also the most capable person in the Capital's Aerospace University.    

    

He graduated from the Electricity Department of Hua Ting Transportation University in 1935. In 1939, he received a PhD in Aerospace Engineering from the Shanghai State Institute of Technology in Y Country.    

    

He was the founder of the Aerospace Automatic Control and the Stun Travel Studio, so he was also known as the King of Spikes.    

    

Now, Prof. Lin was close to 70 years old, but he was still working on the front line. For example, he was still teaching at the Aerospace University.    

    

Qin Guan did not alert anyone. He quietly walked into the University of Beijing Aerospace. The spring wind blew, and the trees rustled. There was a lively scene everywhere.    

    

Qin Guan rarely came to university, because after coming here, he always felt that he was superficial. The elites here were the true pillars of the motherland. As for himself, he had the advantage of the system in his brain.    

    

Outside the teaching building, there were many climbing tigers. When spring arrived, the withered vines began to spit out countless green teeth. At this time, the sound of professors lecturing could be heard from inside the teaching building.    

    

Qin Guan slowly walked in from the back door and sat in the last row.    

    

On the lecture table was Prof. Lin. His face was very big, and he wore a pair of black-framed glasses. His hair was already white, and he was dressed in a mountain suit. He was washed to the point that he was old, but he was very clean and tidy.    

    

"This is the complex method to find the coefficient algebraic equation. I hope everyone will remember it." Prof. Lin drank some water when he spoke up to this point, but he heard a student talking below him.    

    

"Prof. Lin, your method is great. Compared to other methods, you can avoid complex algebra operations and simplify the steps of the problem."    

    

Teaching in high schools was different from middle school and primary school, especially some experienced old professors. They taught as they wished and the students could speak as they pleased.    

    

Now, Prof. Lin's class was also like this.    

    

After hearing this student's words, Prof. Lin was very pleased. "Yeah, this is our high-level equations' cause solving method. Now, everyone, practice a few more and master the following."    

    

"Prof. Lin, I heard that this method of solving is named 'Lin's Law' in the international mathematics community. Is that true?"    

    

Prof. Lin had finished drinking the water and heard this. His face was full of smiles. "That's right. That was in 1938. At that time, I was 25 years old. This method of calculation was invented, and now, this method is not just based on our paper calculations... In the computing of computers, it is also my method."    

    

"Prof. Lin, you are awesome. We have to do the same as you."    

    

The students below all looked at him with respect. Coach Lin still had a smile on his face. At this moment, he saw a young man sitting in the back of the classroom.    

    

Prof. Lin had always attracted a lot of students in class. A large number of students from other faculties came to listen in. But... No one liked sitting in the back row. Most of them were sitting in the open space in the front row with a small stool. This way, they could see more clearly that Qin Guan was there. It was very sudden.    

    

Qin Guan felt embarrassed when Prof. Lin looked at him like that. To be honest, when he was in university, he used to use this advanced equations to solve the root of the problem. He didn't study it well. In the end, after he learned it... He forgot about it after the exam.    

    

Now, looking at the deductions on the blackboard, he really couldn't remember.    

    

"Alright, let's end today's lesson here." After Prof. Lin finished speaking, he slowly walked towards the back.    

    

Qin Guan stood up and said, "Prof. Lin, you are very good at talking."    

    

A young outstanding talent. Prof. Lin's life was also admirable. Back in Y Country, he gave up his high-paying job and resolutely returned to his motherland. He contributed his life to the aviation career of his motherland. He also made outstanding contributions to the navigation system.    

    

"No, I'm getting old. President Qin, you are the one who is truly young and promising." Prof. Lin said.    

    

Qin Guan was confused. "Prof. Lin, you know me?"    

    

Although Qin Guan did a lot of work, for Qin Guan's safety, the country deliberately kept a low profile. Who would have thought that in university, he would be recognized by a professor?    

    

This was too strange.    

    

"President Qin, I have been waiting for you for a long time." Prof. Lin said, "Let's go to my office to talk."
