There is a lot of valuable information in this text. At present, it is known that it is a third-level civilization named "Luca" in the Guardian Alliance, which rented this drop-shaped probe from the Alliance, carried out patrols in the three-star domain, and then discovered itself.

"It seems...... They have positioned me as a second-level pinnacle mechanical civilization. Don't know what they rely on as a basis for division? What is the gap between secondary and tertiary civilizations? ”

"Well, none of these things matter...... Importantly, my location information has been exposed, what do I do next? ”

Xiao Yu thought silently.

"At present, it is known that the water droplets travel at the speed of light, and this Lucca civilization has also obtained a free fixed-point faster-than-light teleportation opportunity, does this mean that the Lucca civilization has not mastered faster-than-light travel? And the Guardian Alliance has put forward this reward alone, does it mean that this reward is heavyweight enough? ”

"Let me analyze the response plan after the Lucca civilization. According to statistics, from the 37,000 years of the Yuan calendar to the destruction of the water droplets in the 37,000 and 20 years of the Yuan calendar, a total of 20 years, this Lucca civilization has gained a total of ...... by controlling the water droplets to cruise in the three-star domain 900 alliance contribution points. An average of forty-five points per year. It seems that this alliance contribution point is still quite valuable. ”

"Destroy me, or capture me, and you'll get 2,500 Alliance Contribution Points...... I'm worth more than that droplet. Then it is certain that Lucca Civilization will not take the initiative to disclose my information, but will choose to capture me alone. In the division of water droplets, I am the second-level peak mechanical civilization, and the Lucca civilization is the third-level civilization......"

"Do you want to run away immediately?" Xiao Yu thought nervously.

Xiao Yu had less than 10,000 spaceships left, and if he escaped now, Xiao Yu would have enough energy to reach any star within twenty light-years. However, the sentence seen from the water drop logbook: "Get a free fixed-point faster-than-light teleportation opportunity" made Xiao Yu hesitate.

"It took 20 years for the drops to get to me. But it may have been delayed by the exploration of the stopover, that is to say, the Lucca civilization fleet is definitely faster than the water drops, and they will probably come to me in the next moment and twenty years, any time period. ”

"At my speed of 1,500 kilometers per second...... If they get here in five years and go after them, they will have a good chance of finding me, and then, in the empty space, I won't have any chance of winning against the Lukka civilization fleet."

And ...... In the face of such a big fish as me, the Lucca civilization will definitely move quickly, which is dangerous, if you escape...... My mortality rate was 80 percent. ”

"What if...... What about staying in the four galaxies of Tianyuan? ”

"As long as there are five years, I will be able to restore my combat power to the point before the arrival of the water droplet, or even go further, and then, with the help of various space fortresses and turrets, I will be able to compete with the fleet of the Lucca civilization, and even, destroy it!"

"If I win and come to capture me again, they will have to bear the cost of faster-than-light teleportation alone, which may lead to the benefit being disproportionate to the risk, they will probably give up directly capturing me, even if they refuse to give up, if they organize Liliang again, it will definitely take more time than five years, and my chance of escaping is much greater!"

"Let's do the math. Stay in Tianyuan Si, with the help of the location, I will have ...... Forty percent chance of beating it. The mortality rate will reach 60 percent, and then, when they are in conflict, I will have more time to escape, and the mortality rate in the process of escaping will be reduced to 10 percent. ”

"Comprehensive calculation, if you run away directly, the mortality rate will be 80 percent, and if you stay in Tianyuan 4 and defeat them once and then escape, the mortality rate will be 70 percent."

"Moreover, staying in Tianyuan IV, I will have the opportunity to once again improve my technology to a higher level during this time, and the winning rate will further increase. Moreover, I will have enough time to gather supplies and prepare for escape, and the benefits to me are self-evident. ”

"Then it's decided, stay in Tianyuan Four!"

Xiao Yu made up his mind.

"It's just a pity that I finally got an opportunity to develop science and technology peacefully, but now I have been shattered by this droplet. What a disaster. Xiao Yu sighed.

After making up his mind, Xiao Yu did not hesitate at all, but immediately started the construction of the four star systems of Tianyuan.

Tianyuan C, Tianyuan B The repair of the interstellar fortress, the construction of the spaceship, the analysis of the water drop shell material, the development of science and technology, etc., a lot of things are waiting for Xiao Yu to do.

Xiao Yu's first thing was the resumption of work at Tianyuan A, the spaceship construction base. Originally, due to the limitation of computing power, Xiao Yu had stopped the construction of the spaceship, and now the spaceship has lost half of it, and the construction of the spaceship must be accelerated.

Inspired by the waterdrop chip, Xiao Yu began to develop a ternary computer. Usually, computers are binary and are made up of zeros and ones. But ternary computers are different, and ternary computers are made up of one, zero, and minus one. One represents true, one negative represents false, and zero represents unknown. The ternary computer is closer to the way of thinking, and Xiao Yu has estimated that under the same hardware conditions, the ternary computer will be more than five times more efficient than the binary computer.

If the ternary computer is successfully developed, Xiao Yu's computing power will be able to control 100,000 spaceships at the same time, and it will be more flexible and efficient. At that time, the improvement of strength will be leapfrogging.

In addition to the construction work at Tianyuan A, the upgrading of various weapons in the asteroid belt is also in full swing. In Xiao Yu's estimation, the battle form of the Lucca civilization will not be much different, in this case, the various hidden mines in the asteroid belt and the controlled turret will play a great role, and it will not be basically useless in the face of water droplets.

At Tianyuan B and Tianyuan C, several satellites that have been damaged by water droplets have not yet returned to calm, which means that on these satellites, it will not be possible to carry out various engineering repair work. Xiao Yu had no choice but to start construction work on the remaining alternative satellites.

In addition to the construction of the inner galaxy, Xiao Yu learned from the pain and began the construction of a large-scale information collection system. The specific content is that all the signals are covered within a range of 20 billion kilometers outside the galaxy, so that as soon as the Lucca civilization fleet appears, Xiao Yu can immediately detect it.

At the same time, after experiencing the Moluton civilization and the Water Drop incident, Xiao Yu also began to think about the way of interstellar warfare. Xiao Yu launched a large-scale war deduction in an attempt to find a more advanced and efficient way of interstellar warfare.

Xiao Yu's defense liliang is all above the ecliptic plane of Tianyuan Four. Interstellar space, on the other hand, is three-dimensional. But Xiao Yu was not worried that the Lucca civilization would bypass the zodiac plane and directly raid the base camp.

The way of interstellar warfare is similar to the way of warfare in ancient times.

In ancient times, warfare was flat, that is, fought only on the ground, it was two-dimensional. In a two-dimensional war situation, various castles are equivalent to points on this plane, and castles are one-dimensional. However, until the castle is conquered, the attackers generally do not dare to bypass the castle and attack directly. Because liliang can be stored in the castle, after the attacker bypasses the castle, it can be dispatched from the rear to form a two-sided attack on the attacker.

In the same way, the four star systems of Tianyuan are three-dimensional, but the interstellar fortress is equivalent to a two-dimensional one, if the Luka civilization dares to bypass the interstellar fortress and directly attack Xiao Yu's base camp, Xiao Yu will have the opportunity to attack it from both sides. Generally speaking, as long as a civilization has a little common sense of war, it will not make such a low-level mistake.

After thinking about it, Xiao Yu came to a conclusion that the defender will always have an advantage in one more dimension than the attacker.

Xiao Yu decided to take advantage of this advantage. If there is enough time, Xiao Yu plans to equip 10,000 spaceships each at Tianyuan C and Tianyuan B, which will each include two city-level spaceships.

The interstellar fortresses of Tianyuan B and Tianyuan C will greatly increase their combat capabilities.

Xiao Yu entered the busy construction business. Under the pressure of life and death, Xiao Yu burst out with a previously unimaginable enthusiasm for work, every minute and every second, Xiao Yu was in the midst of intense construction, and his work efficiency was at least several times higher than when he first arrived in the Tianyuan Four Star System.

Thousands of monitoring satellites equipped with ultra-long-range communication devices were manufactured, which were scattered by Xiao Yu in orbits ranging from tens of millions to 20 billion kilometers from Tianyuan, and monitored the entire Tianyuan Four Galaxies.

In addition to the Tianyuan A base, Xiao Yu also opened up the second and third construction bases in the asteroid belt, the satellites of Tianyuan B and Tianyuan C.

In order to speed up the construction progress, Xiao Yu developed several sets of manual programs with extremely high intelligence, which were distributed on the Chongqing and Tianjin, so that these two supercomputers diverted part of the computing needs, and Xiao Yu supported it.

The construction of the entire Tianyuan Four Star System is in full swing.

However, the huge sense of crisis has always been pressed on Xiao Yu's heart. Xiao Yu was shouting silently all the time: "Hurry up, hurry up, Lucca civilization will come at any time!" ”
