Vol 2 Chapter 49: fully prepare

There are obviously many secrets hidden in the giant rhinoceros and the apparently intelligent little creature, but now there is no chance to see them show their talents. The body of the giant rhinoceros is still there, and the little creature does not have any residue.
According to the characteristics of the small creature, Lin Xi and Chu Jungui named it messenger. It doesn't look like a black hand behind the scenes.
Now that the messenger's whereabouts have been discovered, Chu Jungui knows that Difficulty Four will soon appear. The fourth difficulty scenario will have air forces. Although it is only a short-range attack, there will not be air combat long-range forces, but the presence of air forces will make the ground defense facilities completely vacant.
Lin Xi had doubts about the difficulty of Chu Jun's return. For example, why did the air combat long-range troops in difficulty 5 not appear in advance?
Chu Jungui's answer is that most of the herds here have evolved naturally. There are only traces of faint human adjustment, and it is even difficult to determine whether it has been adjusted by human factors.
Among naturally evolved creatures, being able to fly has an absolute advantage, and generally does not need to evolve long-range capabilities. Even for ordinary people in the 35th century, hitting airborne targets is still a laborious task. It must be assisted by a chip or even an automatic aiming system. A bird without a chip wants to spray something, and it must be accurate It's so low.
Such creatures have probably been eliminated in nature.
As for difficulty five, Chu Jungui has made preparations. The optimization of the biomass rifle in the chip has been carried out for 9 hours, and it can be completed in less than an hour. At this moment, the prototype of the new rifle can be seen vaguely. After Chu Jungui made final adjustments to the plan, he continued to build fortifications on the top of the cockpit while the design optimization was completed.
He built a single soldier reinforcement on the top of the cockpit. The position uses alloy instead of wood as a support, scrap bricks as the center armor layer, and two layers of mortar and one layer of bone pieces are brushed inside and outside. This defense can at least make the spineback 100 meters away helpless. At the same time, Chu Jun returned and installed a bracket with a simple hydraulic retreat device, which allowed Lin Xi to automatically return to the original position after shooting, so that it would not be overturned by recoil.
As for Lin Xi, she continues to do what she likes: buried mines.
When Chu Jungui completed the fortifications, the new biomass rifle design was completed. Like the sniper rifle, this fourth planet version of the rifle has also been changed beyond recognition. At first glance, it looks like an insect covered with heavy shells. The curve is a bit weird. The whole body's blue-violet hue adds a sense of mystery.
The body of the new rifle is close to 1.5 meters, which is not as bulky as a rifle. The most striking thing is the magazine for the square box below. After Chu Jun adjusted the design, it was no longer an assault rifle, but a real machine gun!
This alien version of the machine gun has a muzzle velocity of 1200 meters and a rate of fire of 600 rounds per minute. Although the rate of fire is not outstanding, it is already quite amazing for weapons made of biomass materials. After all, the rate of fire of weapons made of biological materials is naturally insufficient.
And this rate of fire is close to the limit of Chu Jungui. Under full-speed shooting, Chu Jungui was able to make each bullet aim at a different target within a certain angle, and hit the machine gun into a precision rifle.
This is the confidence of Chu Jungui's response to air forces. As long as the herd dared to come, Chu Jungui will let them know what is called anti-aircraft fire.
The new alien version of the machine gun can use ordinary rifle bullets, but its power is limited. It also has specially optimized bullets. Special machine gun bullets are half larger than rifle bullets, and the charge and power are increased accordingly, but the rate of fire will be reduced to about 450 rounds per minute.
A slightly lower rate of fire is not a big problem, so the power is greatly increased, and two rounds of bullets can kill a monster. Three shots can destroy the spineback. Only specially designed bullets cannot be made directly from existing raw materials. They must be processed by an editor before they can be used.
Chu Jun checked the ammunition reserve in his hand. The latest wave of attack was destroyed by the fission bomb, so the material was lost by nearly half, and finally only the material equivalent to 80 strange beasts and nearly 200 spines were harvested. All these materials were used by Chu Jun to make bullets, and eventually harvested about 2,000 rounds and 100 rounds of sniper rifles. Counting the remaining inventory on hand, the two had about 2,500 rounds and 150 sniper rounds.
These ammunition reserves are enough to launch a medium-sized military operation. After all, Chu Jun returns with a machine gun in his hand, and the damage he caused alone is equivalent to a precision shooter in a platoon. Lin Xi is not so exaggerated, but when it comes to real strength, he is comparable to a class of elite soldiers.
Chu Jungui built another alien machine gun for Lin Xi to provide continuous firepower. At this time, Lin Xi had gone back and forth a few times, and he couldn't care less about the return of the emperor. When he came back, he settled in front of the workbench, and buried his head to make some weird little things.
Chu Jungui casually asked how many mines she laid, and then got a shocking number: 19 types, 210 in total.
After seeing the most basic thorn mines and chain-cut mines, Chu Jungui suddenly felt that the herd of alien stars was a bit sad.
At this time, Lin Xi's chip was still developing an alien version of the organic matter separator, and Chu Jungui continued to build five polymer battery packs. After adding 100kw of energy supply, he began to produce the original organic matter editor.
The organic matter editor can re-edit the raw materials to form specific molecular structures to achieve specific properties, which can be physical, such as super-hard, super-extensive or high temperature resistant, or chemical, or chemical Physically common.
Chu Jungui's current materials, including mortar, animal bones, and spines, can be re-edited for enhanced performance. The raw material editor also needs a design drawing. When Chu Jungui's chip was designing an alien version of the sniper rifle and machine gun ~ EbookFREE.me ~, by the way, he analyzed some materials and gave an editing and improvement plan.
Chu Jungui entered the editor's design drawing into the workbench. The total manufacturing time was about one hour, and the final power consumption was 40kw.
"Energy is enough." Chu Jungui thought, about to press the button to start manufacturing, suddenly remembered the incident, and looked at the busy Lin Xi not far away.
He sighed, canceled the editor's manufacturing process, and instead made an additional device for the refining furnace: the electrolytic module.
The base version of the refining furnace has a total of two expansion ports for installing functional enhancement modules, and the corresponding ones are more than 20 different functional modules.
The electrolytic module consumes about 50kw, and its volume is equivalent to a quarter of a refining furnace, which is about the same size as a dishwasher in the home star. Chu Jungui installed the electrolytic module on the expansion port reserved for the refining furnace.
There is no oxygen on planet four and no water on the surface, but there are a lot of oxides. These oxides can be electrolyzed in a refining furnace to release oxygen.
With oxygen, there is also water, and the two people no longer need to live to the limit.
