The asteroid belt is a dense area of asteroids located between the orbits of Mars and Jupiter in the solar system and is composed of more than 500,000 asteroids.

The fleet continued to accelerate, and soon broke away from the gravitational pull of the Earth and flew directly towards the asteroid belt.

Soon less than a month later, the spacecraft has come to the asteroid belt, although it is very lonely to sail in the universe, but this voyage is different, because the operation is in the solar system, and because of the success of particle communication technology, the communication between the rented space fleet and the earth is faster, although due to technical reasons can not be synchronized now, but the current communication is much faster than the previous quantum communication technology, In fact, even in the asteroid belt, they are still very close to Earth compared to the entire solar system, so they can often chat with their families.

As soon as they entered the asteroid belt, the alarm system on the spacecraft sounded, because directly in front of their fleet, about a million kilometers away, there was an asteroid blocking their way, and this asteroid was about two hundred meters in diameter.

If the scientific and technological level of their fleet this time is still stuck in the era of the war with the Pangu Star Ruer Star at that time, then they must dodge this asteroid, after all, although the entire fleet was strong at that time, for such an asteroid with a diameter of more than two hundred meters, even with the most powerful electromagnetic railgun at that time, it would still be impossible to destroy.

You can only use a nuclear bomb to destroy, but it is really overkill to use a nuclear bomb to destroy this asteroid, after all, Heda is one of the most powerful weapons of mankind so far, and it really shouldn't be wasted in these places, not to mention that there are not only small stars in the asteroid belt at this time, but also countless civilian mining ships of the Ming Empire, so using nuclear bombs to destroy this asteroid is a huge threat to these civilian spacecraft.

When the alarm sounded, Zhu Lei ordered all the spaceships of the entire fleet to open the electromagnetic shield, although the electromagnetic shield is very weak for physical attack defense, but it is better than nothing, at least reduce the force of impact, after the fleet has all opened the shield.

"The particle cannon is getting ready!"

Zhu Lei's particle cannon on his flagship is actually what people usually call a particle beam weapon, and the particle beam weapon is collectively called a beam weapon with a laser weapon, because the particle beam weapon can reach the speed of light or sub-light speed of attack, if you attack the target in the atmosphere, the particle beam weapon will collide with the molecules in the atmosphere to produce a beautiful beam, but it will not produce such an effect in the universe, because there are no atmospheric molecules in the universe, or the atmospheric molecules are very thin. If the energy of the particle beam weapon is relatively small, then there will be basically no beam effect, let alone the colorful animation.

However, the particle cannon launched by Zhu Lei's spacecraft is different, because the particle beam they emitted is very powerful and can even destroy a planet the size of the earth, so the beam they emitted has this white light.

The basic principle of particle beam weapons is to use a magnetic field to accelerate particles and then launch them in a cluster, using the energy generated by the high-speed impact of the particle clusters and the action of the secondary magnetic field to instantaneously evaporate the target.

In fact, as early as 20 years ago, particle weapons in various countries basically had very mature theoretical research, but due to various problems, especially energy problems, they have not been able to deploy in actual combat.

However, now 20 years have passed, due to the rapid development of human science and technology, this weapon has moved from theory to actual combat, and compared with 20 years ago, this weapon has been substantially improved in terms of range and power.

And Zhu Lei and they want to attack the asteroid directly in front of them this time to test this weapon, after all, this weapon has never been used since it was equipped on the spaceship, and it has not even been tested, after all, the power of this weapon is too huge, but the particle beam weapon with low power has been tested many times, and the test has been very successful.

With Zhu Lei's order, the particle cannon of the Yongan spacecraft emitted a dazzling light, shooting towards the asteroid in front of the fleet.

Because the attack speed of the particle cannon is very fast, the attack of the particle cannon is completed in the blink of an eye, and because the speed of the particle beam is very fast, especially in the universe, its speed can be said to be almost the same as the speed of light, and even equal to the speed of light, so in more than three seconds, the particle beam emitted by the particle cannon hit the asteroid.

There was no earth-shattering sound, just a flash of red light, and the asteroid in front of it had disappeared from the radar, so it can be said that this test of the particle cannon was very ideal, especially the attack power and attack speed of the particle cannon.

However, although the particle beam weapon equipped by Zhu Lei's Yong'an, that is, the particle cannon, is very powerful, the energy consumption is also very powerful, just such an attack, the energy consumed is enough for Zhu Lei's Yong'an to fly in the universe for a year.

And all the energy reserves on the Yong'an are all combined, and they can only make this ion cannon fire a few hundred times, so you can imagine how powerful it is.

Although this asteroid can be directly destroyed even with the electromagnetic railgun on the spaceship, the electromagnetic railgun has now become a standard equipment in the Ming Empire, whether it is an electromagnetic railgun for individual weapons, or an electromagnetic railgun on various spaceships, so this kind of weapon does not need to be tested, and all the attack data has complete data in the database of the Ming Empire.

The particle beam weapon is different, although there was a relatively perfect theoretical support 20 years ago, and now it has been more mature in theoretical research, but the real use of actual combat has only been developed in the past few years, so for this kind of weapon all kinds of data, especially the actual combat data of the Ming Empire can be said to be very small, so it is very necessary for the test of this kind of weapon, especially the high-power particle beam weapon equipped on the spaceship.

The particle beam weapon on Zhu Lei's spaceship, that is, the particle cannon, has reached a range of nearly one astronomical unit, of course, it has no power at this distance.

In fact, the particle beam weapon above after Yong'an, That is, the maximum power attack range of the particle cannon is within 0.5 astronomical units, and the particle beam weapon is much worse than the electromagnetic railgun in terms of attack distance, after all, the electromagnetic railgun is a pure physical attack, because there is no air and gravity in space, so if there is no interference, the shells fired by the electromagnetic railgun will continue to fly down at the speed when they are fired, until the attack reaches the object, but compared with the beam weapon, the attack speed of the electromagnetic railgun is too slow.
