Three days later, the temporary base of the moon.

Fifteen massive excavation Transformers roared across the lunar surface, mining in the open pit mines in the distance. Behind the excavator, improvised rail minecarts non-stop transport the ore to a steel mill five kilometers away, where it is processed at depth.

Next to the steel plant, a robot manufacturing plant has also been built, the laboratory has completed the specific data required for robot equipment, hundreds of small first-class control transformers are on standby on the production line, waiting for the raw materials to be transported to process them into working engineering robots.

Starting today, the robot manufacturing plant will be fully operational, and the first completed engineering robot will be born in this workshop, and from now on, there will be more and more robots of all kinds out of this manufacturing plant to participate in the comprehensive construction of the moon.

The helium-3 nuclear power plant, which is about to be built, is still under construction and will not be put into operation until about half a month later. Previously, the vast amount of energy required for the temporary base was supplied by a huge solar power plant located ten kilometers away from the base.

The sunlight on the moon is very strong because there is no atmospheric barrier, and the Transformers' solar power generation technology is much higher than that of the earth, and the photoelectric conversion efficiency is as high as 95%, so the energy supply for the entire base at this stage is more than enough for the time being, but soon the project will be expanded through the nuclear power plant to supply energy.

In the spaceship docked in the base, Ye Chen looked at the giant stereo projection in front of him, which was the monitoring screen of their moon take-off and landing field.

In the picture, a large triangular spaceship hovers over the landing pad. Suddenly, several white rays of light appeared from beneath the ship, a stream of high-velocity particles from the propulsion of the engine.

With a strong tremor, the spaceship quickly hit the sky and flew in the direction of the earth.

In order to be able to establish contact with the humans on the earth, Ye Chen appointed thirty transformers of different sizes to carry out the mission of visiting the earth this time, their visit will definitely cause a sensation on the earth, so every move will be remotely monitored by Ye Chen.

The spacecraft left the lunar orbit and quickly headed for the Earth, and not long after, it had already entered the Earth's atmosphere according to the predetermined orbit.

The first step of the spacecraft is to fly over all the major countries in the world to maximize the impact of this event.

When the spacecraft approached the earth, because the spacecraft did not turn on the stealth function, all the parties on the earth had already learned the news that the UFO was approaching the earth at a high speed, but at this time, they were too late to prevent the unidentified flying object from entering the earth, because its speed was too fast, and it seemed that they didn't care about the high temperature caused by the friction between the bulkhead and the surrounding air at high speed.

When the spacecraft flew into a low-altitude orbit, it finally slowed down, and slowly flew over the large city from east to west.

The ship did not fly strictly westward along the main line, but deliberately passed several large cities in a kind of mesh route, and as it flew over the cities, it reduced its speed to below the speed of sound.

At the moment when the spacecraft was just approaching the ground, dozens of fighters quickly chased in the direction of the spacecraft. The alien spacecraft landed on Earth, and I don't know what purpose, and now the entire military department is boiling.

Dozens of warplanes surrounded the ship from all sides, and constantly released warning messages.

"Unidentified alien spaceship, unknown alien spaceship, we don't care where you came, please land in a safe area, if you enter the city, we will intercept and shoot you!"

But this mysterious alien spacecraft was obviously unmoved, and continued to move according to the predetermined orbit, directly ignoring these dozens of combat planes that were eyeing each other.

After a dozen security warnings, the fighter group had received orders to open fire on the unidentified ship, which was already approaching the city.

"Boom! Rumble! Rumble! ”

An air-to-air missile quickly tore through the sky, surging towards the not very huge unidentified spacecraft in front of them, all the pilots were a little apprehensive, after all, this UFO had never shown how strong its combat effectiveness was, but they all knew in their hearts that if the spacecraft in front of them was really an alien spacecraft, the technology that could travel through the vast space to reach the earth was definitely beyond their reach, and maybe it would be wiped out today.

Soon, to their shock, all the missiles close to the ship inexplicably stalled as they approached the ship, and the navigation system began to fail, and the expensive missiles seemed to turn into a pile of scrap metal and fell to the ground without causing a single explosion.

This shocked all the pilots, the strange spaceship in front of them was too evil, all the missiles had no effect in the slightest, and the only weapon that could be used on the plane was the cannon, but they didn't believe that the cannon alone could shoot down the plane.

Immediately afterwards, a strong electromagnetic interference spread, and the electromagnetic intensity was so high that the electronic systems of these dozens of aircraft were paralyzed in an instant. As if out of order, the ship stumbled to the ground. The radar system is paralyzed, the navigation system is paralyzed, as if all systems are paralyzed.

However, the danger did not last long, and after a brief period of system paralysis, these dozens of fighters finally recovered, adjusted the angle of the aircraft in time, and avoided crashing on the ground.

Now they seem to understand that this unknown spacecraft does not seem to have malicious intentions, and the electromagnetic interference just now seems to be only a warning to them, and it does not kill them.

Unable to stop the alien spaceship, the spaceship sailed directly into the city, and lowered its flight altitude again, slowly passing over the city.

No one noticed that when the ship appeared over the city, a number of scouting mechanical insects the size of flies were launched from inside the spaceship, which quickly spread towards the city.

These mechanical insects will collect all kinds of information on the earth, including the reactions of the people, the media, the political axes, the army, and the reactions of various organizations, and all the collected information and intelligence will be transmitted to the moon in case Ye Chen and them find the problem in time and prepare in advance.

Below the city, countless crowds poured into the streets, looking at the alien ships that were flying swiftly in the sky with shocked expressions. Fortunately, there is no malice on this ship, otherwise it would have caused panic.

At this moment, the media seems to have gone crazy, and the streets are lit up with shining shooting lights from time to time, and it is believed that the news of "UFOs descending on Earth" will be reported on the covers of major newspapers the next day or even that night.

"Alien spaceship, look, it's an alien spaceship!" The people were already boiling, but in order to be able to circle the earth within the specified time, the speed was not slow, and the people on the street only saw the spaceship flying by for a few seconds.

For the news of UFOs, whether on the Internet or **, there are often reports like this, but the flaws of these reports are that there are too few people who have seen these UFOs, or they do not look like UFOs, but other natural phenomena and the like.

But today's extraterrestrial spacecraft landing on Earth will silence all skeptics, because there are too many people who have seen alien spacecraft today, and the spacecraft is full of science fiction, it can't be other natural phenomena.

It's definitely an alien spaceship, and needless to say, it's what everyone thinks they have.

The ship flew past the city, then accelerated into the sky above the next city, causing another wave of frenzy.

Of course, the incident of this alien spaceship landing on Earth brings people more deep worries, and it is not known what this spaceship Earth is for, whether it is to conquer Earth or to visit by the way, or to bring the seeds of civilization. Many supporters of the Doomsday are mentally prepared for the destruction of the world, and intend to escape the disaster by entering the life-saving equipment prepared in the past if something happens.

But what is strange is that the spaceship did fly away, as if it was just coming to slip around.

Moon base, in front of the three-dimensional picture from the monitoring facility, Ye Chen quietly looked at the image in the picture, the corners of his mouth curled a little arc, now the spacecraft suddenly descended to the earth, because of the calmness shown by the spaceship, it didn't seem to cause much panic, people were more curious in their hearts, anyway, if this was really an alien spaceship, there was no need for them to resist, anyway, it was useless to resist.

Judging from the monitoring screen, the spacecraft has flown past several major countries, and important cities in various countries have been visited, I am afraid that at this time, the whole world is still in the shock of the sudden landing of alien spacecraft!

"Almost, let's get started!" Ye Chen looked at the surveillance screen and ordered.

So after flying around the earth for a full circle, the spacecraft hovered over the Pacific Ocean, and an invisible electromagnetic wave was quickly launched from the spacecraft as the center in a specific frequency band, and the major political axes should be able to receive this news at this time.

In the presidential office of the White House, President Obama was watching the TV broadcast in shock at this time, he didn't notice that there was a black fly lying near the window, it was a reconnaissance mechanical insect sent by Ye Chen, but its alien was no different from ordinary insects, basically no one would find them.

The office door was opened, and a clerk walked in, holding a document and saying to Obama: "Mr. President, just now there was a radio wave on that mysterious spaceship, and they sent the message: Please go to the spaceship over the Pacific Ocean at 5 o'clock today, and wait for the arrival!"
