The new materials provided by Roland are very useful, not only for the manufacture of armor plates, but also for various other fields that require the use of light alloys.

Chu Jungui used new materials to build a batch of structural parts to frame the living area of the mobile base. However, he didn't really want to create a living quarter, as soon as the load-bearing frame was set up, Chu Jungui put down the follow-up work and instead built an armored bunker on the load-bearing frame.

Seeing the size and shape of the bunker, Lin Xi and Roland, who were familiar with the Federation's equipment, knew that the illusion of a comfortable life was shattered again.

Sure enough, as soon as the bunker was built, Chu Jungui beckoned the colonel, and the two of them carried the chariot cannon into the bunker together. So the mobile base had the front main gun.

After about 300 kilometers of mobile base, Lin Xi stopped at the side of a very secluded forest surrounded by two mountains.

She turned on the jet power, flew into the air and looked around, and said, "It's pretty good here, Jungui, what do you think?"

Chu Jungui also nodded: "Very good, Horizon 2 will be built here!"

The colonel was a little puzzled and asked, "Shouldn't you keep on the run? Why stop here?" ”

"Build a base and produce something. ”

"We were so close to our original location that we didn't get away at all. It won't be long before you get caught up. Roland was a little anxious.

"300 km is just right. When the Federation fighters catch up, it's just time to surprise them. Okay, don't be verbose, come down and work!" Lin Xi patted the colonel on the shoulder and pointed to the ground.

The colonel was helpless, jumped off the mobile base, and said: "You don't know Joseph and William, they must send a large army next time, and they may even lead the team in person." ”

"What kind of rose is that? If he hadn't died, he would have been the next one. Chu Jun returned.

The colonel was stunned, thought about it carefully, and said, "It's really possible." ”

The three of them worked together to remove the equipment that had been built from the mobile base and put the tractor down. The colonel and Chu Jungui went to the forest to cut wood, and Lin Xi stayed at the base to arrange various equipment.

By the time Chu Jungui and the colonel returned with a cart of wood, Lin Xi had already built the base into rudiment.

Three workbenches in the center of the base are lined up, the production queue is densely arranged, and the refining furnace and organic matter separator are spread out on the periphery, next to two editors.

The stationary equipment on the mobile base is also not idle, and it is in full production.

Chu Jun looked at the contents of the workbench and was suddenly a little speechless. All workbenches are producing new workbenches. In other words, in the blink of an eye, the number of workbenches will double, from four to eight.

In the production sequence, the finished bench was followed by two new power furnaces, as well as a series of refining furnaces, editors and separators. Lin Xi's final plan is to achieve 10 refining furnaces, 10 editors and 10 separators.

Such a plan also shocked the colonel.

With so much equipment, the demand for raw materials has also increased accordingly, Chu Jungui didn't say a word, and rushed to the forest to cut wood again with the colonel. Lin Xi made a miniature power-assisted excavator for himself, digging and filling the refining furnace on the spot.

After several round-trips, all the new equipment is manufactured and ready for mass production. At this time, Lin Xi took out a design drawing that had just been revised.

To put it bluntly, this design is a double-mounted version of the mechanical keyboard, but the caliber has been increased to 30mm. This increases the power of the explosion to about ten RPGs bundled together, and the range is increased to 7,000 meters. The rate of fire has been reduced to two rounds per second, but because it is a twin load, the firepower has increased.

This double-mounted version of the mechanical keyboard is three of them. The remaining five benches began to produce ammunition at full capacity.

At the same time, Lin Xi sent a defense map to Chu Jungui and the colonel, and with the help of the favorable terrain surrounded by mountains, three different batteries were built to cover the only entrance passage with all-round firepower.

Seeing the defense map, the colonel understood that Lin Xi was preparing to use the Federation's misjudgment to give the pursuers a head-on attack.

According to the current data, the Federation believes that it will take at least 30 hours to run 300 kilometers from the mobile base, but in fact, Lin Xi and Chu Jungui only took 6 hours, and there is a time difference of a whole home star day in between. No matter how fully the Federation estimates the firepower of Lin Xi and Chu Jungui, at most it is estimated to double. However, by the time the three double-loaded large mechanical keyboards were in place, Lin Xi and Chu Jungui's firepower had actually increased by nearly ten times!

Roland seems to have seen the scene of the desperate struggle of the Federation chariot under the overwhelming firepower.

He shuddered, didn't dare to think about it, and buried himself in his work.

At this moment, Rose sat on the roof of an armored combat vehicle, looking into the distance, her eyes burning with rage. He was still wearing the scarlet trench coat, and although the damage had been lightly repaired, it looked even more shabby.

The trench coat was covered with simple individual armor, which also made his figure look bloated. His left hand was covered in bandages, and blood was still slowly oozing from the bandages.

Beside him, it was still the huge sniper rifle, but the color was a little dirty, and there were several deep scratches on the gun's body, which completely destroyed the master's exquisite carved pattern.

The crack in the eyepiece is still there, and it seems that he has no extra backup, and the color of the turban is also uneven, and another layer is wrapped inside, blocking the hole in the outer turban. It's just that there is some color difference between the inside and outside, which is difficult to avoid.

The chariot roared forward, like the wind chasing lightning.

His fists were clenched, his whole body trembled slightly, and his teeth rattled with hatred. Behind him, there were more than 20 armored combat vehicles, of which there were also 3 real main combat vehicles, and the rest were also infantry personnel carriers with relatively thick armor. At least in the face of the bombardment of mechanical keyboards, it will not be blown up in the first round.

He did not return to the base, but communicated urgently to the base, and transferred a batch of tanks and supply vehicles over, and merged with the tanks stationed in the same place, forming the force in front of him, and pursued again.

At present, this force was won by him at the risk of violating military orders, and it is also the largest force that can be divided from the base at this moment. Rose staked her reputation and military exploits for this. If he loses again, then Joseph and William will fight in person. So there is no room for loss in this battle.

Even in the midst of a rage, Rose was able to keep her composure, calculating in detail the progress and firepower of her opponent's escape. In the worst-case scenario, the opponent builds a second mechanical keyboard for long-range crossfire coverage. However, his main combat vehicle is fully capable of defending against the bombardment of mechanical keyboards, and the maximum range of the main gun is 10 kilometers, and it also has a range of 6 kilometers on Planet Four.

At this moment, the combat power of this tank unit is more than four times higher than the original five high-speed combat vehicles.

So this time, the Rose will never give the opponent another chance.
