Even if William expanded the fortress by four times in one fell swoop, the direction and content of a research and development center were very limited. In the interstellar era, the real R&D centers were at least at the urban level, and there were even crazy research planets.

For Herman, a research center of tens of thousands of square meters is really not enough, and the space inside is very tight just to stuff the main brain, not to mention the laboratory that needs a lot of space. So in the end, only one direction of research could be chosen, and Herman himself had no right to decide, and could only be chosen by William and Joseph.

"We now have the following directions to choose from, one is the metal material direction. We will focus on new alloys that can adapt to the climate and environment of Planet Four, thus opening the door to mass production of native weapons and equipment. The second is energy research. This is not only about energy supply, but also about various energy weapons, as well as research on energy defense shields, various engines, and so on. Of course, this direction is much more difficult than the previous one, requiring a lot of people, masters, money, and patience. ”

"Good in both directions. Joseph said.

"What else?"

"The third direction is to establish a biological research center, focusing on the biology and environment on this planet. This direction...... It requires a lot of money, space, equipment, personnel, and sufficient security forces. By the way, be patient. ”

"What will be the end result of this direction?"

"We will completely unravel the secrets of the planet's ecology and figure out the causes of the beast tide, with the ultimate goal of transforming the planet into a ...... Well, that, sightseeing planet. ”

Both William and Joseph knew that Herman originally wanted to talk about a habitable planet, but it was too difficult to realize, so they changed the name to a tourist planet.

Without thinking, Joseph said, "The third one doesn't take into account! By the time you figure out their secrets, we'll have already become their food." We don't need you to study it to know that they eat meat!"

Herman shrugged and said, "You're a general, you call it your way." ”

William pondered for a moment, his gaze switching back and forth between the two different styles of research centers, carefully contrasting. After a while, he made up his mind and said, "Maybe it's the direction of metal materials." It is the fastest to build, and it is the easiest to produce results, and it is also smooth to transform new achievements into combat power. Unless we put our tanks in a fully enclosed warehouse, they won't last more than ten days before they break. ”

Joseph pondered, then nodded, "That's fine." In the past, we fought every day, and most of the equipment was consumed in less than two days, and we could not wait for natural damage. Now that the nest has been destroyed, it is necessary to research new equipment. ”

William nodded, "Then it's decided." ”

He finally pointed to a tall tower rising from the ground in the center of the base and said, "This is the beacon tower, with it, we can guide three transport ships to land at the same time, and the supply capacity of the base will be qualitatively changed." ”

"Beacon Tower? And this old thing? And why is this thing so big, it's almost a building. ”

Herman looked helpless, "No way, the beacon tower must have a mastermind, and all we can use at the moment is Cambrian." In terms of function, a Cambrian may not be as good as the two of you generals. ”

"So you have to make it that big?"

"Yes. Herman snapped.

Joseph's eyebrows furrowed and he was silent.

"That's exactly why the new base is going to be built so big," William said. ”

"Since this is the only way to go, then we have to think of more ways to defend the system. I think it's better to build a satellite fortress in each of the four directions, connected by underground passages. This effectively distributes the pressure on the main base. ”

"That's it. We're going to build beacon towers first, so we can guide more convoys down. Oh yes, when will the new transport ship be completed?"

Herman checked the personal terminal, and then said: "The development of a new generation of disposable transport ships has been completed and is in full production. It is expected that after 4 o'clock, we will receive the new transport ship. More than 95% of the parts of the new carrier can be dismantled and reused, and the remaining parts can be recycled through refurnace. By design, the new carrier will not lose more than 30% of its losses when penetrating the ion storm. ”

"This success rate ......," Joseph sighed.

"The success rate is already pretty good. According to the notice, we now need at least five transport ships per day for replenishment, plus a large mobile planetary material processing plant. ”

Herman took the order and left. When he was gone, Joseph said, "More than 500 lives a day, hey!"

"Not much. Don't forget, since we built the Shadow Fortress, the daily casualties are in the thousands. ”

"That's a war death, how is it the same? Forget it, don't say it, it's useless to say it. ”

William squeezed out a rare smile and said, "When the new fortress is built, we will never sacrifice so many warriors again." ”

"I hope so. ”

At this moment, at Base 2, many fighters are working desperately, and no one is resting. When Chu Jungui and the others came back from reconnaissance, they also knew the news that as many as tens of thousands of war beasts had gathered, and the fear was enough to make the laziest guy become diligent.

Large-scale editors have sprung up to produce heavy alloys. Although the survival grade composite materials are obviously better, there are now problems in the supply of raw materials, and there are not enough war beast materials.

Lin Xi added a layer of heavy alloy outer armor to all kinds of weapon towers, and how long these weapon towers could survive in battle was the key to determining the outcome of the battle. As long as Chu Jun is there, the more weapon towers there are, the better, until his brain is overheated.

At this point, half of the workbenches have been replaced with a Factorio version of the fourth-order workbench, and then a large-scale update is carried out with the refining furnace. The old refining furnace was dismantled in situ and replaced by a new fourth-order general-purpose refining furnace and a recycling-type refining furnace.

The new fourth-order detector has been producing results, and the new data has greatly increased the efficiency of the refinery, which can produce more than a dozen base metals and non-metals such as silicon, with less than 20% of the substances classified as residues.

The dismantled equipment can be directly fed into the recycling refining furnace, which can recover most of the materials, but the organic matter will be consumed, and the Alien version of the recycling furnace needs to be developed to solve the problem.

In addition to refining furnaces, there are all kinds of editors, pretreatment machines for various special materials, more than ten kinds of construction machinery, and even various living facilities, which need to be built.

There are thousands of problems, and it becomes easy to solve when it comes to Lin Xi. She directly crossed out all the living facilities, and regardless of the little princess's complaining eyes, she turned the saved materials into weapon towers.

The little princess felt that she had to do something, or she would never want to take a bath.
