At around 8 o'clock in the evening, the moon is bright and the stars are sparse, and everything is quiet.

Under the leadership of Li Jianfei, Chen Hao, Zheng Tiehao, "Divine Detachment" Huang Congli and other senior PLA personnel entered the most secret place inside the farm.

This place is close to the mountains, easy to defend but difficult to attack. Although there are only a dozen connected cement houses, it is a three-step post and a five-step post, and the guard is very strict.

Xia Fang, the head of the farm, was waiting here. He saw Li Jianfei coming from afar with Chen Hao and others. He quickly came forward, saluted Chen Hao with a powerful PLA military salute, and whispered: "Principal, student Xia reports to you! After coming to the United States, the student has been lucky enough to have fulfilled the mission you assigned secretly!"

After returning a military salute, Chen Hao said, "Xia Fang, this person is extremely important to our great cause. If you and Jian Fei can tie him silently, you should remember a great achievement."

After receiving Chen Hao's praise, Li Jianfei looked happy, but Xia Fang was calm and said solemnly: "Principal, you teach students' abilities. You must remember them and remember them in your priest."

Chen Hao smiled but said nothing. Lu Liwei, who was standing beside him, was Xia Fang's old boss. He smiled and said, "Xia Fang, don't be polite to the principal. You will be rewarded for your merits and punished for your mistakes. This is the discipline of our People's Liberation Army!"

Xia Fang nodded, Chen Hao observed the surroundings and praised: "Xia Fang, you have a very good place here! I just walked along the way and saw that the farm was loose outside and tight inside, and there were many secret whistles. Even if I wanted to touch it, it would take some effort!"

Xia Fang showed a rare smile and said gratefully: "I have to thank Vice Chairman Huang Sande! He knew that we lacked capable people here, so he sent 50 experts from Zhigongtang to listen. With these experts joining me, I can protect the unspeakable secrets on the farm as solid as a soup and without leaking water."

Speaking of this, Xia Fang suddenly saw Li Jianfei blinking at him, looking at the strong men such as Zheng Tiehao and Lu Liwei who were laughing around him. Xia Fang said awkwardly: "Of course, if the principal and the officials want to sneak into the farm to inquire about the situation, we will not be able to effectively block it."

"Haha!" Chen Hao patted Xia Fang's arm with satisfaction and said with a smile: "The farm is so big and there are so many secret whistles. Even if I have doubts about this farm, it is difficult to achieve the goal if I want to enter and find out the situation."

Then, Chen Hao stopped talking, waved his hand and said angrily: "Let's go, take me to see Mr. Tesla!"

Nikola Tesla, born on July 10, 1856, died in early January 1943. He is a world-renowned inventor, physicist, mechanical engineer and electrical engineer. He is the most outstanding and mysterious genius in human history and is known as the superman of science.

Tesla did not study hard in middle school and liked to play cards and raise birds. After graduating from middle school, Tesla suffered from cholera for two years and almost died of illness. After surviving, it became a genius for some reason.

In 1875, Tesla entered the Comprehensive Technical College of Glazi despite his parents' wish to become a pastor.

Five years later, Tesla was admitted to the Technology Department of Charlie University in Prague. However, due to financial reasons, he took a leave of absence from school a year later and worked as a design engineer in Budapest. There, Tesla participated in the construction of a new call center and improved the equipment and sound effects of the phone.

Then, Tesla's creative ability became unstoppable and began to realize its unparalleled scientific potential.

He has made patent achievements in electromechanical engineering, radio engineering, fluid engineering, low temperature engineering, geophysics, vacuum technology, aircraft technology, etc., and has become the first scientific generalist in the late 19th and early 20th century.

Tesla's patents in various countries, including all its unapproved patents and all inventions with patent value, add up to more than 700.

Tesla is not only a scientist dedicated to exploring and grasping unknown natural phenomena, but also a skilled craftsman.

Some of his experimental achievements, such as the artificial manufacturing of fireballs and lightning, cannot be imitated even if they use the most advanced equipment of the 21st century.

Tesla's most valuable achievement is the discovery of the principle of rotating magnetic field and the invention of a multi-phase AC power supply system and an AC induction motor.

His most famous invention is the "Tesla Coil", a high-frequency resonance transformer that distributes parameters, which can obtain high-frequency voltages of millions of volts.

The circuit and principle of Tesla's coil are very simple, but it is not easy to adjust it to resonance with the environment perfectly. Tesla is a person who is particularly good at this skill.

Tesla later invented the so-called "amplification transmitter", which is now called a high-power high-frequency transmission line resonance transformer, used for wireless transmission tests.

Tesla's wireless transmission technology is worth mentioning. Tesla regards the earth as the inner conductor and the earth's ionosphere as the outer conductor. Through its amplification transmitter, it uses the radial electromagnetic wave oscillation mode unique to this amplification transmitter to establish a low-frequency resonance of about 8 Hz between the earth and the ionosphere, and uses the electromagnetic waves surrounding the earth to transmit energy.

This system is different from the energy transmission mechanism of modern radio broadcasts, and is similar to the relationship between alternators and transmission lines in an alternator network. When there is no power receiving end, the transmitter only exchanges with the resonant cavity of the heaven and earth without function, and the entire system has very little active loss. If it is a general radio broadcast, all the transmitted energy will be lost in the space.

Tesla did not have the financial resources to realize this claim during his lifetime. Later generations theoretically fully confirmed the feasibility of this plan, proving that this plan is not only feasible, but also extremely efficient, ecologically safe, and does not interfere with radio communications.

It just involves energy broadcasting and free access around the world. Under the existing political and economic systems, no one actually cares about this proposition.

In addition, Tesla was one of the first scientists to successfully produce fluorescent lamps and discover and study x-rays. He first discovered the ruby ​​laser effect, as well as the point electron microscopy effect.

Tesla is also the originator of radio remote control. He first implemented the logic principle of computer "And-gate" using resonant circuits.

Tesla also first explained the principle of radar, and first used his homemade high-sensitivity receiver to receive radio pulse signals from outside the sky. He detected cosmic rays, invented a revolutionary bladeless turbine, etc.

Tesla's life was bumpy, and his achievements were inseparable from his courage to take risks. He "dare to be the first in the world" and worked to the end.

The extremely high voltage research he was engaged in was full of life dangers and often risked his life to perform various demonstration performances.

His best move is to let millions of volts of high-frequency voltage pass through his body, showing an amazing discharge effect.

During the research, he was subjected to electric shock and irradiated with large doses of x-rays. When studying magnetic storm coils, he felt the impact of magnetic storm on life consciousness, and magnetic storms of the same intensity could make the nearby metal foil evaporate without a trace.

Tesla was unmarried for life and was hit by a taxi in his later years. Despite this, he still lived to be 86 years old and devoted his whole body to the cause of science.

When Tesla passed away, except for tons of documents and materials, no property or last words were left behind. It was really touching.
