A month's scientific investigation soon passed, and the final discussion meeting began.

Driven by Zhang Yuan and others, the new human civilization has passed the No. 17 backup plan, and the rest is to persuade the TOS civilization to choose this plan.

In theory, there should be no big problem.

After hearing the various requirements put forward by mankind, the experts of TOS civilization carefully calculated all the formulas of scheme 17 and confirmed that there was no big mistake.

The head of the other party nodded slightly and said, "you're right. Considering the depreciation of various mechanical equipment, our industrial strength will decline slowly in hundreds of years, until after a thousand years, basically all the machinery we bought from the trading market will be scrapped..."

"At that time, a lot of effort will have to be spent to produce their own substitutes for these machines. Alas, the adjustment of the production line is also quite troublesome. In any case, there will still be a great decline in industrial strength. Developing a second war star will be much slower. Unless we increase our population. "

"The blind expansion of population is unfavorable to the development of civilization itself... The population of a civilization has the most appropriate boundary value. Beyond this population, efficiency will decline. "

"Integrating these points and developing only one war star is indeed a better choice."

"But the risk will be greater... It must be completed on time and in quantity every year, otherwise it is likely to fail, resulting in a planetary impact, and everything will be over by then."

Captain Ke said unhurriedly, "Sir Thomas, you know, there can be no perfect scheme with large benefits and low risks."

"Scheme 17 has been voted through after internal discussion in our civilization. As long as it can be completed on time and in quantity, the risk can be controlled. Both of us have paid a huge price and are eager to obtain curvature technology, and it is impossible to give up for no reason... "

"This is our consensus, so I think the risk can be controlled."

These TOS people were silent for a long time. Their TOS civilization spent a lot of amoeba points for the whole plan, and most of the details were consumed.

The same is true of new human civilization.

Both sides run to the place where the bird doesn't shit and there is no cosmic string, not for failure, but for success.

The new humans have no intention to pit them, otherwise it will be a great enemy of life and death.

Finally, they discussed for a long time and thought that since mankind had such courage, why didn't they have TOS civilization?

It would be great if the whole scheme could be completed with the painstaking efforts of a generation.

After the meeting, there were no special twists and turns, and the two sides finally chose the No. 17 alternative.

The planet that the two civilizations need to develop is code named "js131", and the big ice hockey that needs gravitational attraction is code named "js144".

After such a decision, a large number of engineering equipment were moved to the "js131" planet to start the first phase of the project - the construction of the central quark energy chamber. This is a new energy technology, which can only be used in super large flagship. Of course, Planetary Fortress can also be completed in 30-40 years in theory.

Zhang Yuan breathed a sigh of relief and watched the shining small suns appear in the high sky, which is the nuclear fusion light with high light intensity. With the continuous relocation of various equipment from the war star, the robot is constantly busy.

Because the Planetary Fortress rented from the interstellar trading market is too close to "js131", the gravity of the two planets attracts each other, and a series of changes have taken place in the motion orbit of "js131".

In order not to collide with each other, the huge engine of the Planetary Fortress starts slowly, emitting bright ionic flame.

These intense ion beams are thousands of kilometers long, like a gorgeous rainbow in the universe. The two sides have always maintained a distance of 20000 kilometers, which is equivalent to rehearsing people's plans in advance.

"Unfortunately, if we have more amoeba points, we can accomplish a lot by relying on this rented planet alone." Zhang Yuan pondered secretly below.

But soon shook his head and sighed that he really wanted too much.

He listened to many scientists nearby talking about some formulas of attraction between planets.

The War Star built by human and TOS civilization for more than 1000 years cannot be controlled so perfectly. At that time, it needs a certain fault tolerance rate.

These details have to be studied carefully over the years.

In this way, 15 days later, all kinds of goods on the Planetary Fortress were unloaded, and the rental time of the war star was about to expire. It was about to return to the trading market.

"Dear new human civilization, are you sure to stay here?"

The person in charge of this Planetary Fortress is still the huge insect "cocoa filamentous wart", he said: "unfortunately, your civilization must decide this problem. The time is coming, and we will return soon. "

Zhang Yuan and others are saying goodbye to the person in charge who has always received them.

The captain had a standard interstellar etiquette with the insect: "we have decided to stay here. Thank you very much for your company over the years!"

Human beings should really thank each other. Without this trading market, it will be very difficult to get to this ghost place.

Even if human beings pay a lot of amoeba points for this, business is business and friendship is friendship. Thank you still.

Mr. captain added: "we hope that after 1400, the interstellar exchange market can send some curvature spacecraft to fly here to pick up our population. We have prepaid part of this amoeba point in advance, but we haven't set a time yet. Now we think that this period is after 1400. "

"No problem, we will keep our promise!" Cocoa filamentous wart showed a faint smile on his face. The whole face looked very strange. It seemed to be looking forward to and wondering: "is your civilization after 1400?"

"Yes."

"Then, please sign your name here and leave an audio image. I will convey your wishes to the trading market. "

Under the guidance of the other party, the captain quickly signed the relevant agreement and walked down with a serious face.

In other words, human beings must complete this project within 1400 hours.

A lot of people are looking at it eagerly, and their mood is complicated. They don't know what will happen in the distant future, and they don't know whether humans will squeeze themselves to the limit and complete these tasks on time.

After the ceremony, Zhang Yuan handed over a small safe and explained, "we left a large safe in the interstellar trading market and want to give it to homologous humans. It should have been kept for a hundred years now."

"Oh, yes, I remember this contract..." cocoa said.

"We also want to add one: if there are homologous human civilizations coming to this trading market after 1400, please give them this small safe."

"But if you come too early, you don't have to give it to them. It's a time limited safe. If you come early, you won't get it. If you come late, you'll get it. "
