"But...... If the planet's gravity propulsion engine is built now, what about the construction of the orbital defense circle around the earth? Zhao Song was silent for a moment and spoke.

"Two can be carried out at the same time, isn't the Circum-Earth Orbital Defense Ring already about to be built? Just increase the intensity of construction. Meng Ke waved his hand and spoke.

As for what Zhao Song was worried about, he knew very well in his heart that it was nothing more than that once the planet's gravitational propulsion engine was built, its instantaneous gravitational force was likely to cause the collapse of the unbuilt orbital defense circle around the earth.

However, the premise is that the circum-earth orbit defense ring has not been completed, but now it has been completed by two-thirds, and the remaining one-third is estimated to be completed within half a year, so Zhao Song's worries are completely unnecessary.

Besides, it's not that the two can't be carried out at the same time, even if they are built together, it's nothing, but it just consumes a little more manpower

Zhao Song also didn't think of this for a while, and only after hearing Meng Ke's words did he react.

Nodding a little awkwardly, Zhao Song asked instead: "Führer, if we really want to leave the solar system, will the matter of the artificial sun also be put on the agenda?" ”

"Well, you're right, this thing does have to be done as much as possible, preferably at the same time as the planet's gravitational propulsion engine." Meng Ke touched his chin and said, "But you don't have to worry about this matter, counting the matter of the planet's gravitational propulsion engine, I'll tell the old men of the Federal Academy of Sciences." ”

"Yes." Zhao Song nodded, then sat back in his chair and stopped talking.

The rest of the discussion was all about things that were not nutritious, and Meng Ke left the council hall after another ten minutes.

Out of the gate, Meng Ke stretched and ordered, "Jarvis, send a copy of the content of the meeting to the Federal Academy of Sciences, and let them start the construction task immediately." ”

"Yes." Jarvis agreed, and went to deliver the order.

Meng Ke didn't know that the content of this meeting directly caused an uproar at the Federal Academy of Sciences, and even several scientists almost didn't fight because of differences of opinion.

Why? It's not because these over-energetic old men want to rush to dominate the construction of the planet's gravitational propulsion engine and artificial sun, which can be regarded as a pioneering thing, and those scientists can't help but be crazy.

Fortunately, Jarvis finally intervened, and the matter was settled, but the scientists were already gearing up to do a big job

In this way, the Earth Federation spent three uneventful three months.

During these three months, the rate at which the sun burns has slowed down considerably, has increased by more than ten percent every day. In this way, within 200 years, the radiation from the sun's rays will be enough to threaten human health.

Fortunately, the planet's gravitational propulsion engine is already under construction, and it will be completed in more than two years at most, but there has been no progress in the manufacture of an artificial sun.

It's not a technical problem, it's a material problem.

When those scientists were full of confidence and wanted to start manufacturing, they realized that if they wanted to create an artificial sun that could simulate the current sunlight, it would be a huge test of the heat resistance of the material.

In fact, if you want to make a small artificial sun, the requirements for the heat resistance of the material are not high, and it is only a test product anyway, and there is not much demand for service life.

But to create a large artificial sun, it is a strong test of the material's robustness and heat resistance, and even the strongest material on earth today can hardly survive the high temperature of the artificial sun for a year.

This is undoubtedly an extremely strict problem, because once the artificial sun is launched, it is impossible to change the material, so the scientists in the Federal Academy of Sciences were suddenly depressed.

It's not that they haven't thought about replacing large artificial suns with small ones, and it's okay to make a new batch after they are scrapped.

The problem is, however, that doesn't work either......

It's not that we don't like how troublesome it is to recreate a batch of artificial suns, but after these small artificial suns are scrapped, the damage to their internal structure can easily cause them to explode. The power of the explosion is equivalent to the detonation of hundreds of nuclear bombs at the same time, and without waiting for the sun to burn faster, humanity will be destroyed by what it has created.

As for finding an asteroid or directly transforming the moon into an artificial sun, these scientists have not thought about this question at all.

After all, now that the earth civilization doesn't even have the technology to make planet fortresses, how can we talk about making more difficult asteroid modifications? As long as they are not fed, these scientists will never think in that direction.

So during these three months, scientists from the Federal Academy of Sciences tried countless methods, but they all failed, and they really suffered a lot of blows.

Fortunately, they also knew that the material problem could not be solved in a while, and although they were irritable, they persisted in trying various combinations of materials, trying to find out the material with the best heat resistance.

While these scientists were anxious about this, the problems they encountered on the artificial sun were also passed on by Jarvis to Meng Ke......

"I remember that there were a lot of super strong alloys in the Yanhuang Kingdom in the past, and there were no suitable alloys in them?" Meng Ke asked speechlessly after listening to Jarvis's description.

Jarvis nodded and said, "Yes, those super-strong alloys are all first-level civilization materials, and they can't withstand the high temperatures emitted by the artificial sun. ”

"Okay." Meng Ke suddenly rubbed his face helplessly, and involuntarily thought in his heart, if only the wisdom brain was still there.

But as soon as this idea emerged, he was thrown away, couldn't he solve this little matter without a smart brain?

But how to solve this problem?

Meng Ke frowned and began to walk around the room, the materials used to make the battleship were obviously not good, otherwise those scientists would not have thought about it for a month without coming up with a way.

Other materials are obviously not possible, and if they were useful, those scientists would have used them a long time ago, so it seems that there are really no suitable materials on earth.

And what about the outside of the earth?

Meng Ke's gaze suddenly fell on the outline of the half-cut planet in the sky outside the window, and a flash of inspiration suddenly flashed in his mind - since there is no suitable material on the earth, is the material on the planet fortress rewarded by the rules of the universe suitable?

He immediately asked, pointing to the planetary fortress; "Jarvis, can the materials used to make that planetary fortress withstand the heat of an artificial sun?"

"Uh...... I think so, the material used to make that planet fortress is a third-level civilization alloy, which should be able to withstand the high temperatures emitted by the artificial sun. Jarvis didn't react to Meng Ke's meaning for a while, but he still answered according to Meng Ke's words.

After listening to Jarvis's explanation, an excited smile immediately appeared on Meng Ke's face, he knew what to do!

Jarvis looked at Meng Ke's appearance, and a bad premonition suddenly appeared in his heart...... (To be continued.) )
