While Li Ruobai was busy underground, Chu Jungui was repeatedly verifying the high-energy beam crystals that had just been researched in the laboratory.

This crystal is mixed with a variety of materials in strict proportions, and then processed at high temperature and high pressure many times to finally crystallize. The preparation process requires a lot of energy, and it takes 24 hours of continuous processing under 10 million kilowatts of energy to obtain a crystal the size of a football.

Chu Jungui was holding a crystal that had just been prepared in his hand, constantly switching his field of view and observing repeatedly. The surface of this crystal is irregularly sliced, and the interior is somewhat chaotic, and large areas of flocculent matter can be seen. In terms of accuracy, it still has a lot of room for improvement, such a large piece of crystal can output a high-energy beam with a power of 500,000 kilowatts after cutting, which is roughly equivalent to the secondary gun of a destroyer.

To be honest, the alpha crystal is still quite primitive, the data in all aspects is lackluster, and the technical indicators are about equivalent to the level of 300 years ago, and even some large star thief forces can't look down on the beam cannon made of alpha crystal. Moreover, due to the use of a large amount of bio-organic material, the purity control of the alpha crystal becomes quite difficult, and not only is there a large amount of flocculent inside, but the distribution of flocculent is also quite random, which means that the quality of the crystal will be uneven, and a large number of waste products will not be ruled out.

However, the so-called waste product is not completely unusable, but the energy conversion index is not up to standard, or the crystal cannot be cut large enough, resulting in insufficient output power.

The advantages of the Alpha Crystal are also very obvious, that is, they are durable and extremely well adapted to the specific environment of Planet 4. The penetration and exhaustion rate of the beam it excites in the atmosphere is far superior to that of a standard beam cannon. In addition, it can withstand continuous excitation for a long time, and the continuous excitation time can reach 3 minutes, which is several times that of ordinary beam cannons.

At this moment, although Chu Jungui was not too short of weapons, the supporting ammunition for these weapons was quite limited. Not to mention anything else, as long as there are a few more battles, the four light patrol main guns in Chu Jungui's hands will have to rest.

Although the alpha crystal is primitive and rudimentary, it is just like a biochip, and it can give Chu Jungui a unique advantage around Planet 4.

Chu Jungui, who was worried about the lack of firepower all the time, immediately began to arrange the production of alpha crystals. At the moment, the total energy supply of Base 2 is more than 80 million kilowatts, which is equivalent to the power generation of the three largest hydropower stations in the era of the home planet. Therefore, the energy in Chu Jungui's hands is quite abundant, even if the refining furnace does not stop day and night, there can always be one or two million kilowatts of energy supply redundancy.

Chu Jungui thought about it, and directly compressed the production capacity of a part of the refining furnace, freed up 40 million kilowatts of energy, and refined 4 alpha crystals at the same time. After such a day, Chu Jun will have 4 beam cannons in his hands. Chu Jungui did not intend to really build 4 cannons, but adopted a simple and crude method, directly connecting the 4 cannons together, so that it became a beam cannon with 4 times the power, but the beam shot was not one, but 4.

The power of this cannon has exceeded 200, which is equivalent to the main gun of a frigate. Chu Jungui did not plan to put it on the starship for the time being, but cleared the position on the roof of the command building of the base, built a gun mount, and equipped it with a biological mastermind to assist in control. It wasn't until the installation of this brand-new alpha cannon that Chu Jungui felt a little safe.

The Alpha Beam Cannon is not the same as the fortress defense cannon installed by the Federation in the base, in terms of power, this is a pure naval gun, and it is not at the same level as the ordinary fortress defense gun. Even the Federation's most advanced main battle vehicle can be evaporated in front of the Alpha Beam Cannon.

After the installation of the Alpha Beam Cannon, Chu Jungui asked people to make a target with armor plates outside the fortress, but it was pierced by a cannon. Satisfied with the power of the Alpha Cannon, the test subject stopped testing it and prepared to continue to expand production.

With the Alpha Cannon, the energy supply of the base began to be insufficient again, and Chu Jungui had to start a new round of power furnace production. At this moment, even the test subjects feel that they have fallen into a strange circle: if the materials are not enough, they need to increase production, and if they increase production, they will lead to insufficient energy supply, and if they repeat the cycle, it will be like adding more water to the noodles, adding more water to the noodles, and finally steaming out a mountain of steamed buns.

After arranging a new round of production, Chu Jungui suddenly faintly felt a vibration under his feet. He immediately rushed to the command station and turned on the scan mode. The command station showed that the source of the vibration was coming from outside the base, and the direction was given. Chu Jungui walked to the window and looked out, and saw a team of chariots and heavy trucks appearing in the distance, roaring towards the base.

This is a regular convoy coming from the shadow of the apocalypse to deploy supplies and personnel between the two bases. It's just that the scale of today's fleet is extraordinarily large, and Chu Jungui remembered that in addition to the laboratory where the alpha crystal was studied, the main personnel of the other 4 laboratories all asked to be transferred to the No. 2 base to work.

Although the shadow of doom is the official base for Chu Jun's return, the living conditions there are really indescribable. Even if hundreds of mobile dormitories were captured after the capture of Base 2, all of which were transported to the Doomsday Shadow, it would only be alleviated. The original single dormitory now needs to accommodate 8 people.

So as soon as they had the chance, the scientists and researchers who were still in the shadow of Doom wanted to move to Base 2. This time, almost all the laboratories had to be moved, and nearly 1,000 researchers were relocated together, and dozens of vehicles of various research equipment and equipment were loaded, plus personnel vehicles and chariots for escorts, a huge convoy of more than 200 vehicles was formed, and it drove into the No. 2 base in a majestic manner.

Chu Jungui didn't expect that after he agreed to relocate, he would actually move so many people in one go. He frowned slightly, and began to reflect on whether his past practices were a little too inhuman.

However, if production is not squeezed in a near-extreme way, Chu Jungui is very worried that the situation will collapse due to insufficient production capacity and firepower at a certain point. The subject has an almost instinctive instinct for danger, and always feels that some large shadow is watching him secretly, full of malice.

Chu Jungui watched the chariot that the convoy drove slowly into the gate of the base, but he always felt that something was wrong. However, the scans showed that everything was normal, and the members of the convoy were also checked before entering the gate, all of whom were soldiers of the Legion. With the subject's memory, he remembered everyone in the legion, and he couldn't make a mistake.

But what's wrong?

Chu Jungui's brows furrowed tighter and tighter, and suddenly his whole body was shocked, and he finally discovered the source of his uneasiness. The vibrations he perceived, the frequency of which was different from that of the chariot convoy!

He immediately turned on the communication channel and shouted, "Ruobai!"

There was no response in the communication channel, only murmur.
