Ten years have passed, and one billion robots have been manufactured. Liu Gan gave Liu Long a surprise, that is, he released the same amount of computing power, allowing the robot factory to produce two more years, and a total of two billion robots were produced.

The limit of Liu Long's manufacturing plan is that about 1.2 billion robots are enough to ensure that the construction period is completed within three hundred years, but more robots can no longer shorten the construction period. After all, some projects cannot be completed faster by the number of robots.

There are also 800 million robots that have been invested in other research and manufacturing projects. The climbing of the science and technology tree cannot be completed overnight, nor can it be achieved overnight. All the improvement and accumulation of various disciplines must be carried out in order to form a qualitative leap.

...

"Traces of energy cluster activity were detected."

One day, the system robot reported to Liu Gan.

"Energy group? The strange thing we encountered when we jumped out of the vortex of time and space?" Liu Gan recalled. According to the system's analysis, the energy group was an early mutated form of the energy clan naturally formed in the universe. It can never evolve into the energy clan, but it is also a very powerful existence in the universe.

"Well, it's in that direction." After the robot marked the specific coordinates of the direction of the energy group and the direction of progress on the star map, it sent it to Liu Gan.

"It seems to be approaching the solar system? It is about a light year away from us?" Liu Gan couldn't help but frown when he looked at the star map.

"Well, if it doesn't change direction, at its speed, it is expected to reach the solar system within three or five years." The robot confirmed Liu Gan's speculation.

"What does it come over and want to do? Destroy the earth's civilization?" Liu Gan murmured.

"No, it is now on the orbit of the Three-Body Civilization and Earth Civilization. It should have smelled your scent, so I came to you. This kind of energy ball is only interested in their kind. After meeting, devouring the other party can make them stronger than before." The robot gave Liu Gan's different inferences.

"similar?"

"It's not exactly the same kind. The energy group obviously only activates the primary intelligence and acts only by instinct. And your intelligence level seems to be close to the extremely powerful energy clan." The robot thought about it and explained in a more appropriate way.

"Anyway, it seems that it's time to break up with it." Liu Gan looked at the energy ball in the star map and made a decision.

When he encountered that energy group, Liu Gan felt that if he could defeat the energy group and swallow the energy group, he might be able to advance the mysterious energy in his body.

Now the mysterious energy can only be increased by one energy level at most. After the promotion, it may be able to strengthen and increase two energy levels. His combat power, mobility and ability to strengthen materials will be greatly improved.

But... According to the system's analysis, this energy group is very powerful. If you fight head-on, Liu Gan may not be able to win the battle. Maybe he will be swallowed by this energy group.

But now, this energy group has actually moved towards the solar system, which is Liu Gan’s home court!

If Liu Gan dares not fight this energy group in the vast space, if his strength is not strong, he will be devoured by the opponent, and his soul will be troublesome. But in the solar system, Liu Gan can design a trap to trap the energy group. If he is not strong enough and cannot swallow the energy group, then trap it first, slowly weaken its strength before swallowing it.

If Liu Gan has such a high IQ, if he still can't handle an energy group that can only rely on instinct to act in most cases, it would be a failure.

"By the way, there is another question. This kind of energy group, including myself... Why can't I swallow the energy of stars to strengthen myself?" Liu Gan asked the system robot while thinking about the plan to trap the energy group in his mind.

The knowledge mastered by system robots is diverse and complex. Without taking the initiative to ask, Liu Gan doesn't know whether it has an answer.

"These are two different energy properties. The energy of a star can maintain the life of the energy group, just like three meals a day, but it cannot make the energy group stronger. If you trace all this back, it may have to be traced back to the moment when the universe was formed. The energy clan was born at that time, but I cannot find more detailed information in memory." The robot had a little regretful expression.

"Okay, it seems that I can only become stronger by swallowing it. I must not miss this opportunity." Liu Gan didn't ask any more questions and issued many instructions to the Mars base. Using the meteorite belt of the solar system, the planets arranged a net of heaven and earth, waiting for the energy ball to fall into his trap.

...

The energy cluster arrived in the solar system seven years later than the expected time. As it approached, it always deviated from its original orbit from time to time, as if it was collecting some kind of energy remaining in the ancient times in the universe.

When Liu Gan was in space, he could sense those extremely hair-like energy, which seemed to nourish him, but because these energy was too weak, Liu Gan did not spend any effort on them.

Just like a hungry normal person, he would not pick up the rice grains that fell on the ground, and this energy ball is just a cosmic vagabond who does not have much intelligence. He is hungry and will not even let go of these tiny ancient energy, which has caused it to delay too long on the road.

When the energy ball came to the Kuiper belt of the solar system, its purpose was already very clear. It had no interest in the sun, Earth civilization and Mars base, but it came for Liu Gan.

The fusiform detection ship where Liu Gan was located moved quickly in the Kuiper belt, and the direction of the energy ball was always locked in the fusiform detection ship, like a hungry tiger pounced on food, and rushed towards Liu Gan extremely frantically.

Its first-time spiritual intelligence obviously did not realize that this was a trap. When Liu Gan stayed somewhere and remained motionless, its speed did not decrease at all, and it emitted a strong energy fluctuation in the void of the universe and swept over the sky.

This momentum made Liu Gan feel an inexplicable tremor deep in his soul, and made Liu Gan realize in an instant that the enemy and us were not on the same level at all... It was obvious that the other party was much stronger than him!

"Boom! Boom! Boom!"

Dozens of energy cannons built in the Kuiper belt were launched together and bombarded the energy ball.

There is no sound in the universe, but Liu Gan can convert various energy fluctuations into sound signals that are convenient for oneself to understand, just like hearing sounds.

The new book "Future Amusement Park" is on the list, and it is urgent to support the recommendation vote! "Thurrying World" does not need to support the list for the time being. I beg my brothers and sisters to change the recommended votes for "Thurrying World" to the "Future Amusement Park". I am extremely grateful! Kowtow!
Chapter completed!
