The documentary ends, and the interior hatch opens. Zhang Hao hesitated and walked inside.

But I saw that the inside was as bright as day, the light was natural, and there was no feeling of artificial light source at all.

The interior of the 30-kilometer-long spaceship is not the design with corridors and rooms that Zhang Hao expected. Inside turned out to be a three-dimensional city, a complete urban design, a steel city with a diameter of about thirty kilometers.

The buildings here go straight up and down, connecting the ground to the dome and also acting as pillars.

The city looks like a greenhouse, but it's not the thin concrete pillars that support the dome, but the large, bright buildings. The buildings are of different thicknesses and shapes.

Different buildings have signs in ancient script:

The seventeenth floor of the residential area and the eighteenth floor of the residential area...... Building 4 of the training area...... Spacecraft Operation and Maintenance Building 9...... Research Building 2...... Medical...... Educate...... Administrative...... Factory...... Catering......

At the end of the road, in the center of the spacecraft, you can see the words 'power zone' from a distance, and there is a red warning sign next to it, you must not approach without permission.

There was an aura here, and Zhang Hao slowly flew forward, looking at this place in a dazzled manner. Although Eternity said that this place belonged to him before, Zhang Hao always had a feeling of unreality.

Also, this spaceship should be just a small spaceship, the core of the moon base, deep in the earth. Can you 'confess the Lord' in the outer layer?

It only took Zhang Hao ten minutes to wander to the center. This is a white enclosed pillar with a diameter of about a kilometer. It is surrounded by a fence.

However, as soon as Zhang Hao approached here, a red laser swept by, and a soft female voice said the ancient words: "Welcome back to the governor, please stand on the teleportation array, the teleportation array will be activated as soon as possible." ”

As he spoke, a light suddenly appeared on the ground in front of the red warning sign, and a teleportation array of about three meters or so appeared.

Zhang Hao hesitated, but still walked onto the teleportation array.

A light and shadow appear in front of the teleportation array, with options on it. Zhang Hao looked at it for a while, and resolutely chose the 'Lunar Control Center' in red font in the center.

Only by entering the control center of the moon can you declare your sovereignty!

This is not the first time Zhang Hao has taken the teleportation array, but the teleportation array here seems to be more advanced than that of Liuli Island at the beginning, and perhaps it is because the teleportation array of Liuli Island is an internal teleportation and has low design requirements.

The strong power surged, Zhang Hao only felt a little dizzy, and the purple and red in front of him were distorted, and he stood still again but had already come to change places.

The surroundings are also bright with natural light, but the environment has changed.

Zhang Hao looked around, he seemed to be standing in the command center, and through the glass, or glass-like materials, he could see the surrounding circles of consoles, or the control rooms dotted within.

It's just that at this time, there are only faint electronic sounds and undetectable machine sounds.

The whole world, only the smell of cold steel.

Zhang Hao looked closer, and there was a row of display windows in front of him, through which he could see the situation of the entire base, including the surface of the moon, space, and even Tianyuan Star and the sun.

Rockets orbiting over the moon are in the monitoring range.

Zhang Hao also saw the reflective facilities around the sun.

It is a cylindrical device, officially called 'Stellar Orbital Light Energy Collector' According to the introduction information, each cylinder is about 100 kilometers long, about 20 kilometers in diameter, and the surface is crystal clear, and another hexagonal mirror is gathered, like a peerless treasure. But this is only in a shrinking state.

Once unfolded, the cylinders form a condenser with a radius of thousands of kilometers, collecting sunlight and reflecting it in the desired direction.

Because it is close enough to the sun, the sunlight is strong, and the light thrust cannot be ignored over time. As a result, the cylinders also adjust their flight attitude and are stabilized by the plasma engine, and the energy comes from the sun, as well as the particles carried by the sunlight and the solar wind.

These "stellar orbital light energy collectors" are true perpetual motion machines, and it is enough to rely solely on sunlight.

And these stellar orbital light energy collectors, although not small, are not large either. At the position of the orbit of the Tian Yuan Star, the existence of these things can no longer be detected, and they are completely obscured by the sun's rays - this is not afraid of being observed by advanced civilizations.

It must be mentioned that the efficiency of the stellar orbital light energy collector is not very high, and the theoretical efficiency is up to 50% - when reflecting light, it also needs to emit light in the opposite direction to balance the power. In addition, energy is required to maintain orbital stability.

Zhang Hao was like a curious baby, observing alone for more than an hour, and finally felt a faint loneliness before deciding to leave.

During this period, Zhang Hao's biggest gain was to imprint his spirit to the control center, in other words, the control center recognized the master.

The science and technology of this cultivation civilization is unique.

By the time Zhang Hao left the spaceship and joined Dugu Junjie and the others again, it had been two and a half hours since Zhang Hao entered the spaceship.

During this period, Zhang Hao also found a smaller shuttle spaceship, which could easily travel between the earth and the moon. The fuel is heavy hydrogen, and if there is no heavy hydrogen, helium three can also operate. However, judging from the current situation of Dayang Group, the ability to extract heavy hydrogen is already the limit of technology.

But after a brief exchange with Dugu Junjie, Zhang Hao was a little dazed for a while: he suddenly got the treasure of advanced civilization, and he didn't know how to arrange it for a while.

Zhang Hao sat on a stone about forty degrees sunburned, quietly looking at the spaceship in front of him in a daze. After a while, Zhang Hao suddenly laughed, and he laughed at himself a little in his heart: I was overwhelmed when I got so much, I just thought too much.

The most important thing at the moment is to develop science and technology, and lead Tian Yuan Star to the space age as soon as possible, so as to be able to deal with the possible threat of the Red River civilization.

Thinking of this, Zhang Hao took out the latest satellite mobile phone and wanted to contact the rocket over the moon. However, at this time, the rocket happened to be separated from Zhang Hao by the moon, and Zhang Hao's mobile phone could not be dialed for the time being.

About half an hour later, Zhang Hao finally dialed, Zhang Hao was not polite, and directly said that he had found a base on the moon, and also found a small spaceship, which could easily travel back and forth between the earth and the moon, so the follow-up fuel supply operation could rest.

However, this time the supply can be rested, but scientific research cannot be stopped.

Although we have obtained the treasures left over from advanced civilizations, it does not mean that we must stop the development of scientific research. In fact, although these things are good, they are not the Ocean Group's own after all. If something really goes wrong, now the Dayang Group will not repair it.

What's more, even if these technologies are good, the more they are 200,000 years ago, or even earlier.

200,000 years ago, the Xuanhuang Civilization was pushed up and down by the Red River Civilization, and 200,000 years later, the technology of the Red River Civilization has developed into something beyond imagination.

Therefore, only being satisfied with what you have gained now is a typical way to take death.

But after discovering these things, Zhang Hao was also a little dazed for a while - what to do next?

Prior to this, Zhang Hao had been leading the Dayang Group to grow by leaps and bounds. The road is blue, the hands and feet are calloused, and little by little it has created the current brilliant Dayang Group.

At this time, he suddenly got such a big cake (it was simply a real moon cake), Zhang Hao was a little dazed for a while.

In fact, it was the recent series of events that overwhelmed Zhang Hao. At this time, he suddenly got the base on the moon, and it was as if Zhang Hao had unloaded his burden. For a while, I was a little overwhelmed.

Two hours later, Zhang Hao started a small spaceship of 100 meters, took the four of Dugu Junjie to the moon orbit, and then picked up the two of them and returned directly to the base of Tianyuan Star in outer space. As for the lunar exploration equipment, it is directly left on the moon.

After returning to the orbit of Tianyuan Star and placing the small spaceship in the space base, Zhang Hao put a parachute on his back and jumped...... Here comes a space bungee jump.

Mr. Zhang has never been so indulgent since he came to this world. When he returned to the ground, he was reprimanded by Zhou Xueyao by pulling his ears.

Fortunately, Zhang Hao was completely confused at this time, regained his state, and found the direction of struggle: first build a space base that completely belongs to the Ocean Group, and then work hard to practice, and strive to break through the realm of cave and void.

As for the bases discovered on the moon, they will be left to the technicians of the Dayang Group to study for the time being, but the spacecraft discovered on the moon can take out three or two of them to take everyone into space bungee jumping and feel the power of the starry sky.

The emergence of spaceships is more conducive to shaping everyone's confidence.

And more importantly, to study a killer technique! and the corresponding tactics! There are some things that can be considered in advance.
