In the silent cosmic void, there are suddenly water-streaked fluctuations, and as time passes, these fluctuations become more and more farther away.

In the next second, a space gate appeared, and then countless biological weapons rushed out of the space gate, followed by large spaceships and countless warships.

"Finally back, starry sky, according to the star map to verify the time." Xiang Qian looked at the cosmic void outside and said to the starry sky.

"Okay, boss."

Although there is definitely no problem with the space passage this time, after all, it is a real prophecy, and there will be no accidents. However, for a more accurate positioning, it is necessary to measure it.

According to the previous star chart, and the operation of the planets of the Andromeda Galaxy, as long as you compare it, you can calculate the accurate time and position.

"Boss, the location of the space passage and the time it is in are exactly the same as the predetermined information." Starry Sky quickly replied.

"Okay, at the same time, all departments, start to follow the continued implementation." Xiang Qian nodded and said.

With Xiang Qian's order, more and more spaceships and warships flew out of the space gate, and soon the star systems on the edge of the H199 star field were scattered, and various factories began to be built inside these star systems.

The racial flagship of the Pabodilon civilization flew out and began to accept the materials collected by the biological weapon legion, preparing to frantically cultivate various biological weapons.

100 years later, the H199 field has become a huge factory, with countless equipment manufacturing factories erected inside each star system, producing countless parts and equipment at every moment. The parts and equipment were assembled into ships and various large, special-purpose facilities that were sent to other star fields.

500 years later. Outside the core region of the Andromeda Galaxy, seven huge factories have appeared. These factories all occupy a star field, and they are frantically manufacturing all kinds of equipment every day.

And the Pabo Dilong civilization has not been idle for these 500 years. Although the race flagship has not left the H199 star field, it has opened countless sub-bases, which is several times more than the factories built by the Earth Federation, and the biological weapons cultivated every day are astronomical.

On this day, Xiang Qian and several people sat together for a meeting.

"As of today, factories have been built for all seven blank areas, and according to the production capacity of the seven industrial clusters, it will be possible to produce all the equipment needed in about 1,000 years, and it will take about 800 years to install those equipment.

Plus the inspection and commissioning work takes 200 years. That is, we still have 2000 years to prepare. Dilong, can you guarantee the cultivation of one trillion biological weapons every day in the time of 2,000 years? Xiang Qian said slowly.

"There is no problem, conservative estimates, in 2000 years, with the number of our biological cultivation bases, we can guarantee the cultivation of 1.2 trillion biological weapons per day, and for 5000 years. 5000 years later. Because of the consumption of materials, the cultivation of biological weapons is at most one trillion per day, and it continues to decrease over time. Dillon said immediately.

"That's good, Sephiroth. Do you have any difficulties over there? Xiang Qian nodded, looked at Sephiroth again, and said.

"No problem, I've already sent twenty trillion clansmen. The equipment is installed and tested, and the data is transmitted back in real time. Once the problem is found. Make immediate corrections to ensure that the plan is not affected. Sephiroth said earnestly.

"Yes. Kaeya, how is the calculation of your academy there, a few lines have been calculated now. Xiang Qian asked again.

"Three routes have been calculated, but the fourth route is more difficult than the first three combined, not to mention the fifth. Now I don't dare to say that I can calculate all the lines in 2000 years, it would be good to be able to calculate five, and the rest can only be made up by Vicadia using the real prophecy. Kaeya said with a wry smile.

"Try your best, it's best to calculate everything, if you really can't do it, there's no way." Xiang Qian said helplessly, he knew how difficult the work of the Mandi clan was, it was tens of millions of times more than the implementation of all the races of the Earth Federation, and it was normal for the preparation time in 2000 to be insufficient.

The next few people discussed it for a while, and then went about their own business.

After Xiang Qian left, he first went to the Academy of Sciences to check the progress of scientific research, and then returned to the office.

On his desk, there was the final plan of attack, which was also a very crazy calculation, in his words, that was the limit of the wave.

After returning to the big universe this time, the Earth Federation did not rush to take revenge, after all, the level of science and technology of the Earth Federation is not as good as that of the enemy, and after entering the enemy's territory, the detection equipment is also limited.

Therefore, after combining the advantages of the Earth Federation, the think tank and the general staff jointly formulated this crazy attack plan.

Since the level of science and technology of the Earth Federation is not good, the Earth Federation must break the control area of the other party, and at least let the various detection equipment return to normal operation, otherwise it is impossible to win at all.

But if you want to break the other party's huge control area, with the scientific and technological level of the Earth Federation, it is really not possible, and finally the think tank came up with a trick, that is, to move the black hole in the core of the Andromeda galaxy and use the black hole to break the large-scale space control power.

Although the Earth Federation cannot move a black hole with the level of technology, the Earth Federation can achieve such an effect through other methods.

The mass of a black hole is so large that even a small fluctuation can cause the entire Andromeda galaxy to change. Similarly, if the entire Andromeda galaxy emits changes at the same time, the black hole will also produce corresponding fluctuations, after all, the force is mutual.

Therefore, the method chosen by the Earth Federation is to unite the forces of most of the star fields on the periphery of the Andromeda Galaxy, and induce changes in these star fields at a unified time to change the black hole.

If the power of one star is not enough, then ten, hundred, thousand...... Hundreds of thousands, when these stars shield their gravitational pull at the same time, and these stars come together again, it will definitely cause an imbalance in the rotation of the planets inside the Andromeda Galaxy.

Especially when all the planets in the field where these stars are located are shielded from gravity at the same time, that imbalance will definitely cause the black hole to fluctuate accordingly.

As long as the black hole changes, then the seven civilization races around the black hole will definitely be greatly affected, after all, it is the core black hole of the Andromeda Galaxy, and the mass is terrifying.

Moreover, the Earth Federation does not change the Andromeda Galaxy in one direction, but in two directions in a straight line, shielding the gravitational force while enhancing the gravitational force, and then swapping, and the black hole will definitely produce very large fluctuations after several times.

Rushing in like all the civilized races before was absolutely stupid, but at that time, no one thought that the other party was so powerful that they would kill tens of thousands of civilized races in an instant. (To be continued......)
