Cleaning up the battlefield is always a good job, even on Planet 4. Chu Jungui has no shortage of energy, no shortage of metals, and even no shortage of rare metals, and the most lacking is people.

This time, the Knights of the Round Table left nearly a hundred chariots, most of whom were still alive. And there was also a considerable part of the infantry who were preparing to clear the battlefield, but because the vehicles were destroyed, they also had to surrender. On Planet 4, which is full of beasts, a person who only wears a suit of armor doesn't want to play any survival games, unless he is a test subject.

In this way, Chu Jungui has a total of more than 800 prisoners of war, and all kinds of wreckage and remaining weapons and ammunition are also a good resource.

The rough-level chariots that Chu Jungui had managed to build with great difficulty were beaten to only 15 left, but it was obvious that the losses of the Round Table Samurai were even heavier.

The unexpected gain is that this time another major general was arrested, that is, the mecha pilot who was broken by Chu Jungui in the opening scene. According to his confession, the current commander of the Round Table Samurai is named Gamble, who is the general of the younger generation of the entire Federation, with very outstanding military achievements, and is also a war maniac.

As for the ground forces being slower than the missiles, the reason is actually in the environment of Planet 4. They somehow got lost and waited for hours to get to the position, otherwise they would have appeared as soon as the missile landed. In that case, Chu Jungui would not have time to ambush the troops, and it would be impossible to knock out the opponent's guards and personnel carriers as soon as he made a move.

Chu Jungui was standing at the head of the fortress, chatting with the major general's captive without saying a word, when he saw Le Mans running over with a piece of armor fragment in his hand, and as soon as he came up, he said: "Boss! Antimony is there, rhenium is there, everything is there!"

Chu Jungui took it and looked at it, and felt that this was a common tank armor, what was strange? Le Mans explained, Chu Jungui understood that this armor was cast by a special alloy, and in order to enhance the performance, a variety of rare metals were added to it. For the base, this is where the rare metals come from. No matter how small the amount of armor is in the armor sheet, it is much higher than that of natural ore.

It is not easy to separate and purify these elements, and the most important thing is to consume a lot of energy. But Chu Jungui lacks everything, that is, there is no shortage of energy.

None of the previous Lancers and Pirate Banners had used this armor. It can't be said that the Knights of the Round Table are more wealthy, but after losing the shadow of doom, the Federation really paid attention to the difficulty of the ground battle on Planet 4.

As for the handling of the captives, it was the same. The so-called old way of doing is to collect everyone's underlying authority and control the personal terminal, that is, to control the battle armor. Those who are willing to surrender are directly absorbed, those who are unwilling to surrender go to work in factories, and a few diehards are directly stripped naked and thrown into airtight rooms. This airtight chamber works better than any other cell, has no breathing mask, is exposed to the atmosphere of Planet 4, and survives for no more than 2 minutes.

The treatment of the cells is naturally not very good, although the Doomsday Shadow Fortress is large enough, but there is no extra space for the prisoners, so the area allocated to each prison is only 0.5 square meters.

There was a precedent for Roland and Wilson, and most of the captives surrendered happily. They knew that there was little hope of being rescued, and on the other hand, Chu Jungui's agent status was especially useful when absorbing prisoners. These are professional soldiers, they can't be regular soldiers, and it's not bad to be mercenaries.

In the end, Chu Jungui roughly defeated 300 million troops of the Federation at a cost of 10 million, and also recovered 20 million materials.

Among the captives, 500 surrendered directly, more than 200 were willing to work, and there were only a few dozen diehards, so Chu Jun had to separate another area from the existing cell to reach the per capita standard of 0.5 square meters.

With this group of people, and the continuous completion of the new power furnace, it is expected that in 2 days, the production capacity of the Shadow of Doom Fortress will be doubled again.

In this battle, the fortress was subjected to a lot of high-powered missiles and shells, and the main structure was once again tested. The results show that the main structure of the fortress is unusually strong, with a lot of design redundancy, which is now useful. Chu Jungui estimated that the strength of the main structure can roughly withstand the direct bombardment of a 20,000-ton nuclear bomb.

In this way, Chu Jungui is a little difficult to choose. The advantage of fortification is that it can quickly increase production capacity, and a large base can be established quickly. And most importantly, it can cope with the tide of beasts.

The bad part is that the coordinates are determined, which will lead to a large number of attacks, such as the missile attack earlier today, which can be done once a day. Federation missiles are not living missiles of the beast tide, they are difficult to intercept, and they cannot always be expected to fly off on their own. Those scientists in the Federation are not vegetarians, even if the IQ on the surface of the planet is halved, the orbital station will not be affected, and sooner or later they will be able to solve the problem.

Looking at the soldiers who were still trying to clean up the battlefield, Chu Jungui repeatedly weighed between fixed and mobile bases, and was a little undecided. That's when Le Mans came running again. This time, the wreckage of a part of the missile warhead was accidentally found while cleaning the battlefield. This is the wreckage of the navigation component, and with Chu Jungui's knowledge reserve, he only recognizes that this is a primitive inertial navigator, but if he goes deeper, he can't say it.

Le Mans carefully opened the broken case, pointed to the hair-fine parts inside, and said: "The cause of the missile's yaw has been found, and some parts of the navigator have magnetized, which should not be done." It seems that the impact of the planetary magnetic field is much greater than expected, and even this semi-mechanical and semi-electronic product cannot escape the disaster. ”

Chu Jungui's heart moved, if even this specially primitively processed missile could not adapt to the environment on the planet's surface, then the progress of federal research would be much slower than expected. In that case, he should still have time.

Chu Jungui built a model, and initially predicted that it would take at least ten days for the opponent to solve the gyroscope problem. Again, this is based on the spacecraft exchanging data twice a day. If, according to the captives, the Knights of the Round Table were only replenished once a day, then the research process would have to be supplemented by two additional days.

At least ten days, at most twelve days, this time is enough for Chu Jun to do a lot of things.

Chu Jungui looked back at the doomsday shadow under his feet. The greatest value of this fortress is the huge amount of infrastructure work and material consumption. He himself wanted to build a fully functional fortress that could accommodate tens of thousands of people, and it would take several months to say anything. In addition, the lancers chose this place to build a fortress, and the terrain was also one of them. The terrain around the fortress is flat, there are basically no major obstacles, and the defensive firepower can be used freely.

To be honest, it was really difficult to get Chu Jungui to give up the shadow of doom like this. If this fortress had been placed in peacetime, it would have been sold for a billion and eight billion.
