On the streets of Yanjing, tens of thousands of heavily armed soldiers in black uniforms lined up, and dozens of dark green-painted infantry vehicles were scattered at various intersections. There was a solemn smell in the air.

There were no flowers, and there was no welcome team with loud gongs and drums. Guided by explosive police motorcycles, black bulletproof buses roared towards Mozi Technology.

...

Three days!

The first global conference lasted three full days.

These three days were called by later generations of historians as the three days that changed human history. Thousands of years later, at the first moment when humans became a level 5 civilization, they deliberately used twelve diamond asteroids to form a planet in the outer reaches of the solar system.

The time of this meeting.

Three days later, when the live broadcast of the meeting appeared on the TV, the whole world stood still. People at home put down their work and stood in front of the TV. The thugs in front of the foreign residential buildings silently put down their torches.

This moment attracted worldwide attention!

On the TV screen, a young man was sitting in the center of the rostrum, while more than a hundred leaders from various countries were sitting in the audience.

The female host's excited voice came from the speaker: "After three days of friendly negotiations, 197 countries around the world have unanimously agreed to Professor Li Mo's proposal to establish the Earth Defense Agency."

"According to the information provided by the Earth Conference, the Earth Defense Agency is a temporary powerful global organization that exists in the process of the earth's fight against alien invasion. It has direct leadership of the militaries of various countries around the world, as well as the right to forcefully recruit materials."

"No country, organization or individual may disobey the orders issued by the Earth Defense Agency for any reason... This is the first time in human history that a powerful international organization has appeared."

"During the meeting, Professor Li Mo was elected as the first director of the Earth Defense Agency with 197 votes, and each of the four permanent members received a deputy director..."

...

At this moment, the whole world is cheering. In the face of crisis, mankind has finally put aside its past grudges and united sincerely. A small flame of hope ignited in everyone's heart...

With hope, everything is possible!

.

Hua Guo, Yanjing, Earth Defense Agency.

A small white building had its plaque changed overnight.

Hundreds of armed soldiers surrounded the small building.

Staff members speaking various languages ​​wore Mozi Technology's umbrella shield uniforms, passed through three strict security checks, and hurried into the small building.

Li Mo stood in front of a vermilion door and looked at the golden door number with still wet ink nailed on the wall. He couldn't help but sigh. With great power comes great responsibility.

Originally he was only responsible for the lives of tens of billions of Pajeros, but now... there are 7 billion more people on earth...

...

"Director, do we need to hold a plenary meeting now?" Zhou Dong, who was following him, suggested in a low voice, "Although the Earth Defense Agency has been established, colleagues are not familiar with each other."

"Every country has a representative in the Defense Agency...so many people, it's so confusing!"

Li Mo came back to his senses and opened the door, "There is no time!"

"Immediately issue the first order, ordering all countries to collect alien meteorites with all their strength. If anyone dares to shirk responsibility... you should know what to do!"

There are no meetings, only orders. Is this the way the Earth Defense Agency behaves?

Seeing the solemn look on Li Mo's face, Zhou Dong couldn't help but tremble in his heart. Unable to say a word anymore, he turned around and walked out of the door.

Li Mo sat heavily on the office chair, hesitated for a moment, and couldn't help but dial a number: "Academician Fang, how is the test of the golden gold I gave you?"

A tired voice came from the other side of the phone: "Professor Li, where did you get this weird substance?"

"Although it looks like metal, it has been tested by high-ray methods and does not have the characteristics of ordinary metal."

...It’s not metal!

Li Mo was overjoyed. It seemed that he had found the right person this time. When he was "copycatting" the engine of an alien low-light speed spacecraft, he discovered that its shell was made of a material that did not exist on earth.

This material is extremely strong and has a very high melting point, which reminded him of a specialty resource of the African country Wakanda in science fiction movies, so he named it gold.

A week ago, he sent the leftover gold leftover from manufacturing the Navigator engine to Academician Fang of the Southwest Institute of Materials and asked him to help inspect it.

"After measurement, the number of electrons in the outermost shell of Doujin is 16...Do you think this is possible?" On the other side of the phone, Professor Fang was very confused.

"This..." Li Mo was so shocked that he couldn't speak. Although he knew that this kind of substance was not found on the earth, he didn't expect it to be so strange.

Because the number of electrons in the outermost shell is an important basis for determining the chemical properties of an element, if the number of electrons in the outermost shell is less than 3, it is easy to lose the electrons in the outermost shell and reach a stable structure of 8 electrons in the outermost shell, making it very metallic.

properties and reducing properties, such as lithium.

The number of electrons in the outermost shell is more than 5, and it is easy to obtain electrons to reach a stable structure of 8 electrons in the outermost shell, making it highly non-metallic and oxidizing, such as iodine.

When the outermost electron of an atom's electron shell is 4, it is easy to lose the outermost electron and gain electrons, so it is covalently bonded with other atoms, such as carbon.

When the outermost electron of the atomic electron shell is 8, such as a rare gas, it has reached a stable structure, so it hardly combines with other elements, such as helium.

However, due to the repulsive force within the nucleus, the outermost electrons of an atom can never have more than 8 electrons, so...

Why can gold trading exist stably?

Li Mo thought for a moment and asked: "Mr. Fang, put these doubts aside for now. I have a request."

"Oh... please tell me."

"Can you design a set of detection equipment to detect meteorites containing gold?" Li Mo said his purpose. Gold, a substance that does not exist on the earth, is extremely strong and has a melting point as high as 10,000

degrees Celsius,

If you have a shield made of gold...

...

"You want to extract gold from meteorites?" Academician Fang asked in surprise, "But how to be sure that meteorites must contain this strange substance?"

"The earth has existed for 4.6 billion years, and countless stray meteorites fall on the ground every year." Li Mo explained: "With so many meteorites, it is likely that there will be one that contains gold."

A sufficiently large base can definitely be achieved with infinitely low probability!

"...You are so optimistic!" Academician Fang said awkwardly: "Detection and refining are not impossible."

"But I need a piece of equipment!"

...

"Send the model number of the device and I will arrange for someone to deliver it to you immediately." Li Mo disagreed. Mozi Technology has already become a gathering place for high-end equipment in China.

"...This kind of equipment does not exist in China." Academician Fang added: "It is the latest high-end equipment in the chemical industry of country m. There is only one in the world and it will never be sold to the outside world."

...

"Send the equipment model number and it will be delivered to you in two days." Li Mo calculated the time required for transportation.

"This..." Academician Fang suddenly realized it and said with a smile: "I almost forgot, you are now the director of the Earth Defense Agency, so naturally you don't need a piece of equipment."

"How about...I'll apply for a few more equipments and take advantage of this opportunity..."

...
Chapter completed!
