"Ship, Captain!" Fu Hongye's neck was as hard as a layer of cement, and he stared at Ye Fei with complicated eyes for a while, but he couldn't say a word.

It is true that blowing up satellites and the alien fleet rushing into the debris swarm are all accidents, and they are not Ye Fei's plans at all, but luck is not part of the strength?

Just like some people win the jackpot after buying a lottery ticket once, and some people never stop in the scorching heat, but they never get the jackpot.

If you can fight this in a war, isn't it the legendary lucky general?

Ye Fei shrugged innocently: "Don't look at me, I didn't expect it either...... Almost, Jiang Xue, the battleship turned around; Scissors, prepare the laser cannon. ”

"Roger!" The Yangtze River made a 180-degree turn under Jiang Xue's skillful maneuvering, and retreated to maintain the original distance from the enemy.

At the same time, the bow of the Yangtze River silently cracked a huge hemispherical concave surface with a diameter of more than one kilometer, and the concave surface was an array composed of more than 100,000 mirrors, each side of which corresponded to a set of lasers, and the combination of mirrors and lasers was the main gun of the Yangtze River.

"The main cannon is fully charged!"

"Choose your target freely and fire!"

At the sound of the order, a little light was reflected on each mirror, but after a split second, hundreds of thousands of lasers converged into a huge stream of light, accurately hitting an enemy ship two light-seconds away.

The high-energy laser turned the target into flying ash in an instant, and at the same time, the four enemy ships behind were affected, although it was not completely destroyed, but a part of the battleship disappeared out of thin air, which was an absolutely fatal blow to the biological warship.

The destruction of five enemy ships with one shot is unbelievable.

"Well done!" Ye Fei raised his eyebrows, "Come again!" ”

"The main gun is being charged, and the current progress is thirty-seven percent, and it will take two minutes." Scissors hastened to answer.

"So long?" Ye Fei, who used the main cannon for the first time, was stunned for a moment.

In the battle in the universe, the two sides are often separated by several lightseconds, and most weapons are powerless against the target at this distance, even the new reconnection cannon on the Yangtze River takes more than four seconds to fly over a distance of one lightsecond.

Four seconds is enough time for a biological warship to fly at full speed at a distance of six or seven thousand kilometers, and if you want to hit the target, you have to depend on luck.

Only directed energy weapons that can reach the speed of light are the most suitable weapons for the space environment, but with the exception of laser cannons, other types of directed energy weapons cannot equip troops for one reason or another, and can only lie rusty in the warehouse of the laboratory.

For example, the biggest disadvantage of microwave guns is that the range is insufficient; Particle beam weapons such as proton cannons or neutron cannons must use particle accelerators that are bulky and consume ultra-high power, and neither the cost nor consumption can meet the conditions for use on the battlefield; The so-called positive electron cannon needs to solve the problem of antimatter manufacturing reserves first.

Laser cannons have absolute advantages in all aspects such as cost and energy consumption.

The Chinese military deliberately designed this fixed super-caliber reflex large laser cannon for super warships in order to strengthen the expeditionary firepower of the expeditionary fleet.

"Captain!" Fu Hongye dutifully reminded, "It takes too long for the main gun to be fully charged, and the distance between the enemy and our ship is only about two light seconds, and I think that 40 percent of the power is enough to destroy the enemy ship at this distance." ”

The effective firing range of the main guns of each ship of the expeditionary force can reach more than five light seconds, and there is still a certain power beyond eight light seconds.

Compared with Ye Fei, Fu Hongye knows more about the weapon data on the battleship.

Not all lasers can be used in weapons, and theoretically speaking, only superconducting accumulators can be created with superconducting techniques to store super-strong currents to produce high-intensity lasers.

However, there is always an insurmountable gap between theory and practice, and the most widely used energy storage device in reality is precisely the flywheel battery.

Even before humans absorbed extraterrestrial technology, they could provide high-intensity electrical energy for directed energy weapons without involving the cutting-edge technology of superconductivity, but among all the methods, flywheel batteries are the only way to physically power them, and they are small, lightweight, fast charging, long-lasting, and free of any exhaust gases.

Moreover, the flywheel battery has a simple structure and easy maintenance, even if the mechanical civilization does not have similar technology. Today, any device that requires high-energy action is inseparable from the flywheel battery.

There are more than 200,000 flywheel batteries installed on the main gun of the Yangtze River, and although the ship's 12 fusion reactors can provide a steady supply of electricity, it still takes a certain amount of time to complete the charge of the main gun.

Ye Fei's eyes lit up: "Go with me, scissors, shoot freely after the charge reaches forty percent." ”

"Roger!" Before he could finish speaking, another ray of death swept across the enemy.

Due to the drop in power by more than half, this cannon failed to vaporize the target directly, but the three biological warships along the way were not lightly damaged, and I am afraid that it is only a matter of time before "death".

The Yangtze River opened fire again and again, and the pursuing enemy fleet could not catch up at all, so it could only watch its own warships being destroyed one by one, and it didn't take long for the alien fleet to lose more than half of its warships.

Seeing that the situation was not good, the remaining warships abandoned the Yangtze River and turned around and ran.

How could Ye Fei, who had already tasted the sweetness, let them go? Immediately ordered Jiang Xue to catch up.

The speeding Yangtze River bit the enemy with lightning speed, the biological warship was constantly destroyed by lasers, and the remaining enemy troops panicked and flew to the friendly forces that had just been hit hard by the asteroid swarm!

Ye Fei laughed so much that his eyes were almost out of sight, isn't this a self-defeating road?

Not only Fu Hongye, but even Ye Fei himself had doubts about the combat effectiveness of the Yangtze River, and originally only wanted to hang the alien fleet and take advantage of the Yangtze River's speed far beyond the enemy, but he didn't expect the power of the main gun to be so strong, which directly gave Ye Fei and all the crew a big surprise.

In terms of the command of the battleship, Ye Fei can only be regarded as average, but in terms of the capture ability of the fighter, no one can match it.

The two alien fleets that had been hit to varying degrees converged, and the total strength had been reduced by more than half, and the attack on the Yangtze River was still continuing.

After a short period of confusion in the converging alien fleet, order was finally restored, and then more than a hundred biological warships dispersed and launched a counterattack like a large net.

The Yangtze River fought and retreated, not giving the outer skeleton a chance to get closer, and it didn't take long for dozens of ships to be destroyed.

Seeing this, the remaining enemy troops no longer had the courage to fight to the death, so they immediately dispersed in a hurry, and randomly found a direction to flee for their lives.

Ye Fei didn't want to let go of an enemy ship, but no matter how strong the firepower of the Yangtze River was, it was only a battleship, and although the Yangtze River, which was lacking in skills, tried its best, it still watched more than two dozen biological warships escape.
