After inspecting the military industry, John then visited the Morgan's media industry, some important industrial manufacturing companies, and some important research and development centers.

After these inspections, John finally made a tour of the important government departments, with District 51 being the last stop.

Area 51 is located in a barren land in Lincoln County, southern Nevada, USA, in 1950 when the military established a nuclear weapons test site in Nevada, it was included, at that time it was numbered as District 51 on the map, so everyone called it Area 51, but Americans have the habit of taking nicknames, so Area 51 is also called Water City, Dream Land, Paradise Ranch, Farm, Box .......

There are many gossip rumors about this place, some say that it is a high-end weapons research base in the United States, some say that it is a secret place for the study of aliens, and even that his underground green room hides alien corpses and the wreckage of alien spaceships.

However, it is difficult to verify who is real and who is fake, after all, this place is inaccessible to ordinary people, and John only knows that Area 51 is the highest level of secrecy in the United States, which is higher than the secrecy level of the nuclear weapons research and development base and the nuclear weapons storage base in Yaka Hill next door, and the rest of John does not know anything.

So John was also very curious about this inspection, not to mention that he had just finished filming "Independence Day".

After more than an hour's drive, John and his party finally arrived at District 51 at 10 noon.

As soon as he got out of the car, John saw a major general with more than a dozen soldiers in camouflage uniforms standing at the door to greet him.

"Sir, I'm Carlson, the head of the Base in Area 51, and I'm welcome to visit Area 51. The Major General gave John a military salute.

John nodded, then mysteriously pulled Carlson aside and whispered, "I heard that there are aliens in there, right?

Hearing John's words, Dani helplessly raised her hand to cover her head.

Carlson was stunned for a moment, and then said with a little crying and laughing: "Sir, I'll introduce you to the base while we go." ”

"Okay, let's go. John nodded.

"This way, please!" Magnus led John towards the parking garage, introducing John to Area 51 as he went.

"Sir, Area 51 is responsible for the most important task of the state, the Ark Project.

When the two atomic bombs of Little Boy and Fat Man exploded over Nagasaki and Hiroshima in 1945, the world officially entered the nuclear age, and the leaders had to think about how we can continue our race in the face of nuclear war.

After the end of the war, the leaders convened thousands of scientists to discuss the issue, and after months of repeated discussions, some scientists believed that if a full-scale nuclear war broke out on the earth, they would migrate to space, build a huge space station in space, and wait for the earth's nuclear purification before returning.

Another group of scientists believes that there is no such advanced migration technology and that the number of immigrants is limited, so they believe that the most likely way to succeed is to establish a permanent base where people can wait for nuclear decontamination in underground bases before returning to the surface.

In the end, after deliberation, the leaders decided to implement the two methods together, so in 1950 thousands of scientists were divided into two parts, one to implement the permanent base program - "Project Noah", that is, the catastrophe emergency control center, and the other to carry out the "Ark Project", which is where we are located, Area 51. ”

No wonder the Cataclysmic Emergency Operations Center and Area 51 are classified at the same level. John suddenly realized.

The spear and the shield are twin brothers, in ancient times, people made swords, and then they had armor, and now swords have become guns, and armor has become body armor.

Now that we have entered the nuclear age, how to survive a nuclear war has become a problem that people must solve. And missile interception alone is unreliable.

"Where are we now?" John was concerned about the issue, though he thought it was unlikely that he would have a nuclear war while he was alive.

"The Ark Project has two major research directions. Coulson said as he led John into the parking garage.

The space in the parking shed was very large, and it was no problem to fit a few transport planes, but there was nothing in such a large space, except for the west corner, where four soldiers in camouflage uniforms were guarding.

Coulson took John to the West Corner, and after walking in, John saw that there was an elevator here, Coulson said hello to the soldiers guarding, skillfully pressed the switch and walked in with John's group, and waited until the elevator door closed, he continued the topic just now.

"The two major research directions of the "Ark Project" are to leave the earth and immigrate to space, and the other is how to ensure that 100,000 people live in space for 50-70 years. ”

Coulson said that the elevator stopped, and when the door opened, John saw a huge space with many people in white coats walking around in it, looking very busy.

"It's all about survival. Carlson walked John out of the elevator and explained: "The researchers here are mainly biologists, water treatment scientists, botanists, medical scientists, psychologists...... They have to solve the food, water, and air we need to survive in space for 70 years...... and other issues to ensure our health. ”

Carlson said and led John and his party to the Plant Research Center.

Upon entering the research center, John saw rows of glass houses with all kinds of plants.

"These are places where botanists grow plants in a simulated space station environment, and 100,000 people living in space for 70 years need a lot of food, so we have to solve the problem of how to grow crops in the space station with a small amount of soil and water. Carlson said as he opened a glass room and walked in with John's group.

There is a patch of tomatoes in this glass house, all of which have already borne fruit, and the yield does not seem to be gone, and there are four or five fruits in one plant.

"Can you eat it?" John asked, looking at a tomato plant in front of him.

"Of course!" Magnus said with a slight smile, plucking a tomato, taking it to the washing station, washing it, and handing it to John.

John took a bite and took a bite, and the sweet and sour taste instantly spread in his mouth: "Yes, it tastes no different from the tomatoes grown outside." ”

When they heard him, they all picked one of their own and tasted it.

"So?" John asked, seeing Dani take a bite of a tomato.

"It's really no different from the tomatoes outside?" Dani replied with a nod as she ate.

"In addition to tomatoes, we experimented with corn, wheat, pumpkin...... Basically, these crops can be successfully cultivated, and now botanists are thinking about how to increase their yields. Carlson said and took John and his party to other cultivation areas.

After visiting the Plant Research Center, John and his entourage then visited the Animal Culture Center, where they met a variety of animals cultivated in a simulated space station environment.

If humans want to survive in space, they need to solve the three basic problems of food, water and air.

At the Water Utilization Research Center, John met how scientists recycle water, and at the Air Research Center, John saw how scientists use oxygen generators to make oxygen.

In addition to the three indispensable things of food, oxygen, and water, there are many important studies in the entire research center, such as gravity, air pressure, energy, medical treatment, and light sources...... Wait.
