With this full acceleration, the speed of the Hope soared to 400 kilometers per second, which was a full fifth of the conventional fuel reserves. But he finally escaped, and Xiao Yu was glad in his heart.

The program on the Hope went into action, automatically grabbing the wood spirit attached to the Hope's shell. At the same time, Xiao Yu had a little curiosity in his heart.

"Weishenme, these wood spirits will take the initiative to attack me? weishenme: These wood spirits will be so much stronger than ordinary wood spirits? ”

Several questions wandered in Xiao Yu's heart.

Suddenly, a strange phenomenon caught Xiao Yu's attention.

Xiao Yu divided the wood spirits captured during this period into more than two dozen parts, each of which had a special high-radiation box to store. What happened was the box that caught the mutant wood spirit behind the confinement.

In this box, in addition to the dozen or so mutant wood spirits, there are also about hundreds of ordinary wood spirits that were caught before.

Through the observation instrument, Xiao Yu clearly saw that those mutated wood spirits showed unusual aggression, they fiercely bit the ordinary wood spirits, swallowing them in one bite, and at the same time, their own radiation intensity also increased.

"This is, this is ......" Xiao Yu was shocked in his heart.

Soon, these dozen mutated wood spirits devoured hundreds of ordinary wood spirits, and then, these dozen mutated wood spirits began to fight and devour each other.

It took a full hour for them to finish the battle, and at this time, there was only one wood spirit left in this box. Its strength reached two hundred and fifty times that of ordinary wood spirits.

Xiao Yu's heart moved, and he commanded the Hope to open a small opening in the box that imprisoned it, and immediately, as if he had received some order, the wood spirit suddenly rushed towards the gap, as fast as lightning. Thankfully, the program moved faster, closing the gap a moment before it could escape.

"In addition to instinct, it also has a rudimentary wisdom!" Xiao Yu was shocked in his heart, "No wonder I will be attacked!" That most powerful wood spirit must have a similar primary intelligence, so it will take the initiative to attack me! ”

"Devour, evolve, I see! However, I think that only some special wood spirits have such abilities. The group of wood spirits I captured at the beginning, although they merged into one, did not show any intelligence. Xiao Yu thought silently, "This will be troublesome." Jupiter is so big, who knows how many wood spirits have evolved wisdom, and it will not be so easy to catch them in the future. ”

"But fortunately, this time the Hope escaped, and in the future, let's figure out a way in the future." Xiao Yu shook his head and ended thinking about this.

More than half a month later, Hope successfully returned to Titan, and then took on the busy task of collecting nuclear fusion fuel, transporting supplies between stars, repairing damaged satellites, etc., and was very busy, and it was only after half a year that it was idle.

Above Titan, everything is in order. Under the existing 93 bases, Xiao Yu built a high-energy physics research institute and began to conduct research on physical theory.

There is no doubt about the importance of physical theories. The development of human society to the present is based on two major theories, the theory of relativity and the quantum theory, established almost 100 years ago. Even all of Xiao Yu's current achievements are also eating the old books of these two theories. Without the study of new theoretical physics, Xiao Yu will soon not know how to develop the road ahead.

As for the next theoretical research, Xiao Yu focuses on the direction of "space". Quantum theory describes microscopic particles, relativity describes macroscopic shijie and combines matter and energy, and under the current physical foundation, the next development direction of physics is likely to be "space".

However, theoretical research is a delicate job, and Xiao Yu does not plan to produce a result in a short period of time.

In addition to the Institute of High Energy Physics, Xiao Yu also built another base, which is dedicated to the study of various special materials. Although the research on the corpse of the black worm and the wood spirit began early on, Xiao Yu did not carry out large-scale research because of his computing power in the early stage. Now, as the construction of the Dawn comes to an end, Xiao Yu finally has enough energy to study this.

The other ninety-three bases have been working well, and a large amount of materials are being produced every moment for Xiao Yu to build. The construction of the "Township" class spaceship, the Dawn has entered the end, and Xiao Yu has begun to try to construct the construction drawings of the larger "County" class spacecraft.

However, Xiao Yu now has almost exhausted all of his titanium and zirconium reserves, and before the arrival of the Earth Meteorite, Xiao Yu has no ability to build a new spaceship for the time being.

After a long wait, Dawn finally ushered in the day of test flight.

The Dawning is several times larger than the Hope, and correspondingly, it is much heavier than the Hope. However, the Dawning uses Xiao Yu's newly developed "Fusion II" engine, which can provide it with more powerful power.

As the order to take off was given, several pale blue flames erupted from the tail of the Dawn, raising a large cloud of smoke on the ground, and in the smoke, the Dawn, which was full of science fiction, took off.

Dawn didn't take off very fast, at least much slower than Hope, and it took a dozen minutes for it to fly beyond Titan's atmosphere.

Xiao Yu immediately tested its performance in all aspects.

Following Xiao Yu's command, the Dawn began various difficult actions in space. For example, flying rapidly for a period of time and suddenly stopped, or told to spin, or fired a laser cannon in flight, etc., it took several hours to toss and turn before Xiao Yu got all the information he wanted.

"Everything was as expected, not bad. The maximum acceleration reached 1.5 kilometers per second, the maximum anti-overload reached 170 times the Earth's gravity, and the maximum speed of conventional fuel reached 1,500 kilometers per second, which is good, very good. ”

Looking at these experimental data, Xiao Yu nodded with satisfaction.

Although the power of the Aurora is not as good as that of the Hope, its endurance, as well as firepower, resistance to strikes, and the maximum speed of conventional fuel, are much higher than the Hope. The loss of mobility is also a matter of no choice, everyone knows that the bigger the thing, the less flexible it must be.

In Xiao Yu's plan, if there is an interstellar war, a spaceship of the Dawn level should belong to the flagship level of the squad, responsible for fire suppression, covering their own attacks and other tasks, and fighting in close quarters, or leave it to a "village" class spaceship like Hope, or a smaller spaceship to do.

Xiao Yu controlled the Dawn, flying proudly in the Saturn system, and there was a big Jiashi who would go up and beat anyone who was not satisfied.

A meteorite with a diameter of about twenty meters appeared in front of it. Xiao Yu's heart moved: "Just use it to test the power of the Dawn's weapon and the strength of the shell." ”

Xiao Yu gave the order to attack, and immediately, the instruments inside the Dawn began to scan the meteorite, and within almost one ten-thousandth of a second, the meteorite's speed, position, orbit, center of gravity, density and other data were obtained, and the locking instrument immediately locked it, the hatch at the bottom of the spacecraft opened, and the launch rack stretched out.

The meteorite, which orbited Saturn 30,000 kilometers away from Aurora, could never have imagined that it would be doomed because of someone's thought.

"Launch!" Xiao Yu gave the launch order, and immediately, the mechanical arm on the launch frame was released, and a stream of fire erupted from the tail of the space missile, and it roared and rushed forward.

The shape of this missile is not the shape of a cylinder commonly used on the earth, but a ball. Because above the earth, the shape of the cylinder and the top cone can minimize the air resistance and speed up itself, but Xiao Yu is different. With Xiao Yu's current level of science and technology, the most important thing to overcome is not air resistance, but the tearing effect caused by strong acceleration on the missile body. Spherical, it can spread the tear evenly to the entire missile body to avoid the missile body being torn apart by strong acceleration.

This is Xiao Yu's valuable experience after thousands of experiments.

Almost instantly, the speed of this spherical missile, under the action of the powerful jet stream in its tail, accelerated to a speed of almost 2,000 kilometers per second, and it took only fifteen seconds to reach the meteorite.

Moments before the impact, the hydrogen bomb was detonated. Under the action of infinite flashes and high temperatures, this meteorite, which has a mass of about several thousand tons, was vaporized in an instant and disappeared without a trace.

A fraction of a second later, a powerful radiant force and heat flow arrived at Aurora. But the Aurora remained unmoved. The strong radiant force and heat did not have any effect on the high-strength shell of the Dawning.

"The power is not bad." Xiao Yu's heart was full of joy.

In the following time, Xiao Yu shiyan the power of laser cannon and high rate of fire machine gun respectively. On this day, the meteorites around the Dawn were considered to be unlucky. Often a meteorite is carefree, and no one is provoked to follow its own orbit, but the next moment, a powerful laser from an unknown source vaporizes it, or a large number of high-speed machine gun bullets come and smash it to pieces.

"Due to the size constraints of the Aurora, the laser cannon is at its most powerful, but when the larger 'county' class ship is built, the power of the laser cannon can be further improved. With so many weapons, even if I encounter some aliens who don't open my eyes, I won't be afraid. ”

Xiao Yu thought with joy.
