The duel is about to begin.

With the confirmation of the real system, this duel is legitimate.

Not only is it legal, but the real system also arranges the venue for the duel between the two nobles, delineates the scope of the venue, and stipulates the criteria for judging the victory or defeat.

The so-called duel arena is a spherical space with an asteroid belt as the center of the sphere and a diameter of 200 kilometers, and it is marked on the tactical map of the two nobles.

The two nobles must fight a duel within this spherical space, and if they leave this area, they will admit defeat, and all onlookers must also leave this area, and can only watch the duel from the periphery.

The distance of 200 kilometers is only a diameter distance, and the two sides look at each other from afar, but in fact they are only 120 kilometers apart.

This distance, in space combat, is just outside the effective long-range shooting distance, which is a relatively reasonable distance.

Regarding the issue of effective shooting distance, Li Yi's Level 4 "Shooting Science" has a very detailed explanation.

Everyone knows that energy rays or clusters move at the speed of light, and there is almost no upper limit to the theoretical effective firing range, but theory is theory after all, and in real combat, in order to lock on and hit the target, the distance between the two sides cannot be too far apart.

In space, due to the problem of space refraction, it is impossible to carry out ultra-long-distance precision strikes 1 light-second away, because due to the influence of the gravitational field, whether it is an ultra-long-distance target seen by people or an ultra-long-distance target searched by radar, its actual coordinates have a large spatial offset.

This is like hitting a beam of energy on the earth facing the sun, but in the end it will not hit the sun, but it is very likely to hit a planet behind the sun, not to mention this phenomenon in this time and space, even in the old time and space, it has been confirmed by astrophysicists on the earth.

The distance of 300 kilometers within 1 light second is also an ultra-long distance, and it is also difficult to carry out precision strikes, one of the reasons is that it is difficult for radar to lock on to moving targets.

Radar electromagnetic waves are also the speed of light, but the electromagnetic waves are emitted to act on the target and then reflected back, even if it is calculated by 300 kilometers, it is equivalent to running back and forth for a total of 600 kilometers, and then the cluster ray hits and has to run 300 kilometers, so not counting the reaction time of issuing the attack command, even the artificial intelligence needs at least 0.003 seconds to act on the locked target.

An ordinary starship, the cruising speed is generally about 300 m/s, within 0.003 seconds, the starship can move about 1 meter, if the attacking starship is also moving, then it is an error distance of 2 meters, this error distance is only a theoretical value, just simply calculate the delay error caused by the speed of light, and do not calculate the relative direction and angle of the two.

Moreover, in actual shooting, after locking on the target, the angle of the turret should move with the target, because the distance is very small, the turret may only need to rotate one micron or even one nanometer if it wants to aim and hit the opponent.

But obviously, such a small rotation distance and angle, no matter how sophisticated the mechanical equipment will inevitably have errors, the so-called miss is thousands of miles, as long as there is a slight tolerance, the energy beam may not know where to fly.

The error caused by the rotational tolerance of the turret is only a problem with the relatively high accuracy of the secondary gun.

If it is the main gun, due to the large size and extremely long barrel of the gun body, the overall structure of the main gun is basically attached to most of the hull of the starship, and the angle that can rotate and swing on the left and right is only within 5 ° or even cannot rotate, which is like the guns on both sides of the ancient warship, the angle of rotation of the barrel left and right is very small, and it is the hull that can be turned sharply, and the base of the main gun of the starship is the entire starship itself.

Therefore, when launching the main gun attack, the entire hull and bow of the ship must be roughly aimed at the target position, otherwise it is to refer to the east and west, and the bull's head is completely not in the horse's mouth, but the hull as the base of the main gun is impossible to make subtle and precise movements in space, and the steering speed is slightly faster or slower, the angle is larger or smaller, or it is touched by a small meteorite, and the main gun cannot accurately hit the target.

Therefore, in space warfare, the range of fire is very different from that of land warfare.

Ultra-long range in space generally refers to a distance of less than 120-300 kilometers, and beyond that is the ineffective shooting distance.

The long-range is between 60-120 km, the medium-long range refers to 20-60 km, the medium-range distance drops to 15-40 km, the medium-range and short-range is between 10-25 km, the short-range refers to 2-12 km, and within 2000 meters, it is the short-range distance of hand-to-hand combat bayonets.

Of course, these are not absolute standards, and if you are lucky, you can hit the target no matter how far you go!

It's just a matter of luck...... It's hard to say, the farther the distance, the lower the probability, there are still a lot of obstacles such as meteorite particles and dust in the space, if the distance is too far, the energy will be consumed a lot in the middle of the way, and even if the target can cause a lot of damage.

Therefore, in contrast, these range range standards that humans have calculated with a large amount of data are the best ranges with the highest probability and the most science.

At this moment, under the provisions of the real system, the two sides are separated by 120 kilometers and look at each other from afar.

Both starships are on the same plane, i.e. on the ecliptic plane of the asteroid belt.

Whether it is the distance or bearing of the two sides, the real system provides the most level playing field environment.

But, is it really fair?

Almost everyone doesn't see it that way.

Even if Li Yi's small assault ship is replaced with three energy cluster guns, the "blood volume" of the medium assault ship is still twice that of the small assault ship, and the launch power is also twice that of the opponent.

If it weren't for the fact that everyone had certain expectations for Lord Earl's intelligence and brain control speed, I am afraid that no one would have watched the battle, because the result was already doomed.

But what if the brain is fast?

The two sides are separated by 120 kilometers, which is obviously in favor of medium assault ships, unless small assault ships can get close to medium assault ships, otherwise the advantage of brain control will be largely resolved.

But obviously, Baron Joel has no reason not to know what the people who eat melons can understand, and Li Yi knows this even more.

"Gotta find a way to get close ......"

Looking at the medium-sized assault ship opposite, Li Yi muttered to himself.

In fact, at a distance of 120 kilometers, even if there is no shelter in the middle, the naked eye cannot see each other.

Li Yi's approach is to divide the perspective picture into four.

Perspective 1 is the normal perspective, Perspective 2 is the target observation perspective, which is used to magnify the target's close-up observation of the target, Perspective 3 is 10 times smaller on the basis of the observation perspective, and the target and its surrounding space are monitored at a medium distance, and Perspective 4 is the tactical perspective, which is the battlefield area God perspective provided by the real system for global observation, so as not to accidentally get out of the battlefield.

This perspective setting method is introduced and explained in detail in "Spaceship Control", and it is the most commonly used perspective setting scheme in space combat.

After learning Level 4 "Spaceship Control", the switching and use of the perspective can directly reach a proficient state, so Li Yi just roughly browsed and checked, and after finding that there were no software and hardware problems, he submitted an application to the real system to start the duel.

At the same time, Baron Joel on the opposite side was also ready for everything.

Duel, on the verge of breaking out!

"System prompt: In this duel, if one side admits defeat, is destroyed or leaves the battlefield, it is considered a failure. The losing side will pay the winning side 20 million Star Coins as compensation. Once both sides are confirmed, the duel begins! ”

Li Yi gave a confirmation command through brain control: "Confirm!" ”

Baron Joel deliberately waited a few seconds to confirm it, and then just as the system announced the start of the duel, four energy cluster cannons fired a salvo at the opposite side!

Obviously, Baron Joel wants to get a head start!

But at such a distance, the radar system can only scan the opponent, but it can't lock it in real time, so this time the salvo is purely to want a blind cat to kill the mouse and fight for character.

At this moment, in Li Yi's No. 2 and No. 3 perspective pictures, four half-meter-thick beams of energy beam light emitted from the medium-sized assault ship and hit straight over!

From a distance, the four pillars of energy beam light look like four thicker segments of red light, and if measured from a close distance, each column of light is hundreds of meters long, but these lines spanning 120 kilometers is a matter of moments!

The moment Li Yi saw the energy light pillar flickering out from the 2nd and 3rd perspectives, the energy light pillar had actually already arrived at his side, and it was impossible to avoid it at all!

However, from the perspective of No. 1, it can be seen that the four beams of energy beam light only crossed a few hundred meters away, and did not hit his small assault ship.

"Heh, spell character? Then it depends on whether your character is good or my skills are good......"

Li Yi smiled disapprenously, ordered the ion engine and the two accelerators to start at full speed immediately, and drove the small assault ship straight towards the other party!

Baron Joel on the other side secretly said that it was a pity, and at the same time, when he saw the other party rushing towards him in a straight line, he did not panic, and drove his medium-sized assault ship to meet him at full speed!

After 20 seconds, the Energy Cluster Cannon is ready to recharge.

At this time, the assault ship piloted by Li Yi had advanced 10 kilometers, while Baron Joel's assault ship was slightly slower, only 8 kilometers, and the distance between the two sides was reduced from 120 kilometers to 102 kilometers.

This distance was still outside the optimal range of the energy cluster cannon, and Baron Joel didn't care, and still hit it with a salvo!

This time he still didn't hit Li Yi, and the nearest pillar of energy gathering light was more than 100 meters away from him.

Li Yi was still rushing forward, still not fighting back, and Baron Joel did not flinch, he still continued to catch up!

Another 20 seconds passed.

The distance between the two sides has been shortened to 84 km!

But the optimal range of those four medium energy cluster guns on a medium assault ship is 18-50 km, and with the additional 20% range bonus provided by the medium assault ship itself, the actual optimal range can only reach 60 km at most!

Still out of the best range!

But Baron Joel didn't care about this at all and continued to fire volleys!

Two pillars of energy light missed, one crossed less than 50 meters away from the side of the small assault ship, and a half-sized beam of light actually hit Li Yi's small assault ship with great luck!

The beam beam is mainly energy damage, and the kinetic energy damage is almost negligible, so it's just that the purple-blue energy shield wrapped around the hull flashed and turned into lake blue, and the small assault ship itself did not shake, and was still rushing forward!

"Energy Shield: 690/750, Remaining: 92%......"

After glancing at the energy shield parameters in the upper right corner, Li Yi still rushed straight with an expressionless face!

At the same time, he gave an order: "Laser cutter No. 1 is turned on, manual operation!" ”

Swish!

A very thin cluster of rays shot straight into the sky!

So, hit the mark!

Just like Beckham's penalty kick, he put an anti-aircraft gun!

But it doesn't matter, it's not a cluster segment that can't be retracted when it's hit, but a continuous ray that can be moved and adjusted!

So the next moment, I saw this ray slashing from top to bottom in the sky!

Burst!

Baron Joel's medium-sized assault ship was swept away instantly, and the energy shield shook slightly......

The audience who saw this scene couldn't help but be stunned!

Nima, 84 km!

This laser cutting ray can be used as a long-range cluster cannon, and it doesn't need a high-power starship to drive it!

Isn't this the creation of a new long-range main artillery weapon?

And it's the only new long-range main gun that fits into a small starship!
