The reason for the cancellation of the levitation shield is that the effective range of the magnetic missile can reach three light minutes, and at such a long distance, neither the Saucers, the Atlanteans, nor other interstellar races can do anything against such a distant target.

The enemy's arms are not long enough to reach their own people, but the Republic's magnetic missiles can hit the enemy, under this premise, the originally very important levitation shield has become a dispensable chicken rib, so the military canceled the levitation shield and saved the important decision of teleporting crystals.

After the Shang clan attacked the solar system for the first time, some people were already aware of this problem, if they had an invincible teleportation shield in the battle, then the losses of the two participating armies would not be so heavy, but such a voice did not attract the attention of the military leadership, and as a result, the second attack of the Shang clan once again led to heavy losses of the fleet.

This time the military is still stubborn, and still has no intention of reequipping the ship with a teleportation shield.

It's not that the military's top brass doesn't want to do this, but the synthesis technology of super-heavy elements is very imperfect, and the speed of manufacturing teleportation crystals is slow, and the military has to strictly control the amount of teleportation crystals used, otherwise it may be that one day, all the teleportation crystals will be exhausted, and it will be too late to think of saving at that time.

The reserve and use of super-heavy elements has always been a top secret of the military, even if it is the top level of the military, there are not many people who know about it, but from the analysis of the military's actions to strictly control the use of the army, it is obvious that the use of the amount far exceeds the psychological expectations of the high-level, so they have to make an act similar to self-destruction of the Great Wall.

Vigorously develop portals. It is also out of the consideration of saving teleportation crystals, if it were not for the birth of the Shang clan, the military of the Republic at this time would have begun to make every effort to obtain the Sail supernova in order to obtain a new source of teleportation crystals.

In any case, the reserve of teleportation crystals must be saved before a new source of teleportation crystals can be obtained.

The materials used to make warships are not strategic materials, and even if the losses are larger, they can be quickly replenished through the efforts of the mechano army; Although the loss of personnel is more troublesome, with the support of cloning technology, it is not impossible to recover.

Since the warships and personnel are resources that can be recovered. Compared to teleportation crystals that can't be restored. It is needless to say which one is lighter and which is heavier.

In addition to the problems of tactics and warship configuration, some other problems were also exposed in this campaign, the most interesting of which was the fleet formation of the Shang clan.

At the moment fifteen warships make up the structure of a fleet. It was the military that made the best choice based on previous campaigns. On the premise that it is equipped with magnetic energy missiles. Either fleet, it has the ability to deal with an entire fleet of Atlanteans.

However, such an organization was a little powerless against the Shang clan, who also possessed faster-than-light weapons, and had to mobilize a large fleet of the three major armies. Therefore, the military has moved the idea of forming a large-scale mobile corps, but whether it is appropriate to do so and how to organize a new fleet will still need a period of detailed planning, and it is only an intention at present.

Soon after the fleet wiped out the invading merchant fleet, the news reached the Xinyuan and drilled into Ye Fei's ears.

However, he didn't pay too much attention to the war in the solar system, not that he didn't care about the situation at home, but that the new source was about to launch another attack.

Ye Fei and his fleet had attacked too many planets in the past month or so, and by now, the entire fleet was filled with a dull atmosphere from top to bottom.

However, the mission continues, and the planet still has to do its best.

The target that Ye Fei had just set his sights on was a terrestrial planet that was more prosperous than ordinary planets and could not meet the standards of prosperous planets, there was no strict defense of the merchant fleet here, and he did not find the planetary defense force field, but Ye Fei felt that it was very tricky, and he was reluctant to give the order to attack.

At first glance, this planet is no different from other planets, but through the magnified observation of the optical system, it can be found that the vast majority of the inhabitants of this planet are actually humans, except for a small number of Shang people living on the surface!

These humans are divided into many very primitive tribes, which look like primitive human societies, but there is also a huge city here, and it is the only city on the planet.

The Xinyuan had already carefully observed the planet through the "faster-than-light" Dafa, and found that a large number of merchants and young men and women came from all over the world every day, and sent young men and women into the city.

At the same time, the city has to take off a large number of spaceships every day,

The city seems to be home to all the Shang clans, and the ships that fly away from the planets are transport ships that transport captive humans to the outside world!

Of course, the human beings here have nothing to do with the Republic, and it can even be said that they have nothing to do with the human beings on the planet.

When Ye Fei saw that the planet was full of humans, he suddenly thought of the human slaves on the list of the Shang clan.

Could it be that this is the planet where the Shang clan specially used to train slaves? So, does the Shang clan also have a planet that raises exoskeleton people?

At this moment, many unrelated thoughts suddenly popped up in Ye Fei's mind, and he suddenly began to doubt the origin of the Outer Bone Man.

The Shang clan sold goods including Exoskeleton slaves, and although there is no evidence that the Exoskeleton people who attacked humans were related to the Shang clan, this possibility cannot be completely ruled out.

After all, the saying that the Outer Bone Man came from Perseus comes from the introduction of the mechanical civilization, who knows if the mechanical civilization has really been following behind the large group of Outer Bone Man butts since the Perseus Arm?

The cosmic beast that once caused great trouble to mankind has now unveiled the veil of mystery, but the cosmic giant beast is nowhere to be heard, until the human race comes into contact with the Seven Clans Alliance, and it is discovered that the giant beast tribe is actually a native Orion arm race.

Such a discovery deepened Ye Fei's suspicions, if the Outer Bone Man and the mechanical civilization were all related to the Shang Clan, then what was the purpose of the Outer Bone Man attacking the solar system?

Ye Fei knew deeply that there were many unexplainable aspects of such inference, such as that with the strength of the Shang clan back then, they could completely wipe out the human race, why did they use such a roundabout method?

But when I think about it, I don't think there's anything wrong with it, maybe it was a race that bought a large number of exoskeletons to create such a big battle...... However, when he remembered the appearance of the Outer Bone Man driving the bone mound on a rampage, he felt that his guess was too nonsense. (To be continued......)
