By this time, neither of them had had a good rest for 20 hours. The test body was okay, but Lin Xi gritted his teeth to support it. Having experienced several attacks by alien beasts, she also knew that now she had to race against time. No one knew what would appear next time.
At this time, the organic matter separator completed the production of a new furnace and stopped. Chu Jungui looked at the mortar reserves on hand, poured them into the workbench, and started making the biomass rifle.
A progress bar appeared on the workbench. After slowly reaching the end, the rifle icon turned green, indicating that it could be manufactured. Chu Jungui also breathed a sigh of relief.
Biomass rifles have very broad requirements for raw materials. Although the composition of the mortar is complex, its physical properties after hardening are outstanding and no worse than ordinary composite materials, so it barely meets the production standards. This is due to the higher requirements for rifle barrels.
At this time, the detection of the alien blood in the organic matter detector was finally completed. Chu Jungui received the report, quickly compared it with the database analysis, and was delighted to find that, as he expected, the blood composition of the alien beast was complex and could meet most of the requirements for making biomass explosives. If one or two different components were missing, there was a high probability that the blood could be extracted from the bones. It can be found in the soil or rocks, if not in the bones.
The only drawback is that the blood content of the alien beasts is extremely small, only about one-tenth of that of normal humans of the same weight, and it is not known how they complete internal circulation.
Chu Jungui immediately nailed a wooden trough and wooden frame, hung several strange beasts upside down on them at once, and began to disassemble and cut them. Animal blood is collected in wooden troughs, and after being processed by the organic matter separator, biomass explosives can be made directly at the workbench.
As for cartridge cases and warheads, there are solutions.
The strength of the alien skeleton is only slightly worse than that of traditional copper bullet cases, but it already meets the most basic requirements and can be processed directly. The warhead can be polished with animal teeth. The alien beast's sharp teeth are very heavy and have a density comparable to steel. After being polished, they can be used directly as warheads.
In this way, Chu Jungui used the blood of four strange beasts to produce approximately several kilograms of biomass explosives. This kind of explosive is far less powerful than the advanced explosives used in survival rifles, so Chu Jungui set the charge of each bullet to 20 grams, so as to ensure that the muzzle velocity of the bullet is above one kilometer per second. In terms of pure power, it is roughly equivalent to a 12.7 mm caliber machine gun in the industrial era of the home planet.
Chu Jungui set up the bullet production program on the workbench, then put all the raw materials in and started the workbench. It's just that the power is not enough. Once the base workbench is started, the portable refiner cannot work.
After waiting for a short while, the output box on the workbench dinged. Chu Jungui opened the output box, took out a newly made bullet from it, and observed it carefully.
This bullet is slightly different from the design drawing. The shell is only faintly transparent, and the liquid charge inside is not pure green, but appears purple in a turbid state. The warhead still has the texture of bones and a heavy texture of metal.
As he watched, another bullet fell into the discharge box. Chu Jun Guimo calculated the time and found that one bullet could be fired approximately every 10 seconds. In this way, all the raw materials would be consumed and 400 bullets would be produced, which would take about an hour.
This production speed cannot be said to be satisfactory, but it is enough to solve the immediate problem, so Chu Jungui put down all other work and concentrated on producing bullets on the workbench.
Chu Jungui picked up the biomass rifle he had just made, loaded two bullets into it, aimed at the petiole of a leaf 700 meters away, and fired one shot.
The sound of the gun was a little dull, different from the crisp and exciting sound of the survival rifle, and the trajectory of the bullet was not that straight, and it had already drifted a bit when it was five hundred meters away. Although in the end, the target was not able to accurately hit the 10 centimeter-thick petiole, but that was due to Chu Jungui's superb shooting skills and high enough naked eye aiming accuracy. The gun itself was still not good enough.
But I can’t choose now. It’s good to have something useful.
Chu Jungui fired another test shot and already roughly knew the various data of the rifle and the bullets. After he fine-tuned the rifle, he handed it over to Lin Xi to familiarize himself with.
Lin Xi took the gun and shot immediately. After three shots, his accuracy improved significantly. It can be seen from this that she is also extremely talented in fighting.
With the rifle in hand, the two of them felt a lot more at ease. Chu Jungui continued to deal with the corpses of the strange beasts, while Lin Xi took the time to adapt to the control of the new rifle.
A rifle alone is obviously not enough. The combat effectiveness of a gun depends entirely on its accessories, at least for non-test subjects. Chu Jungui's eyes are equivalent to all-weather visible and non-visible light sights, and his hands are equivalent to the sum of stabilizers, grips and other accessories that increase stability, but Lin Xi does not have this condition.
While Chu Jungui was dealing with the strange beasts and collecting materials, he was thinking about what kind of accessories could maximize Lin Xi's combat effectiveness.
Just as he was thinking about it, several yellow signs suddenly appeared in his field of vision.
This is a warning that danger is possible but still uncertain. But Chu Jungui saw that although the signs were not very fast, they were all moving in an S-shape towards the base. It was unlikely that they were not malicious.
Lin Xi also received the alarm. She immediately returned, jumped on the roof of the cockpit, looked into the distance, and now turned on the active environmental scanning function of the armor.
Several slowly squirming strange creatures appeared in their field of vision. Their heads are small and round, their eyes are squeezed into thin slits by flesh, their bodies are fat and full of flesh, their limbs are very short, and their short legs move happily but not much faster. There are more than ten sharp thorns of different lengths on their backs, some of which are even longer than their bodies. From a distance, they look like their backs are covered with flags.
"It looks a bit like a spinyback beast." Lin Xi said.
"I'm afraid it's not a good thing."
"agree."
"Go into a thousand meters before shooting."
"I'll fire at 700 meters." Lin Xi was now very aware of the gap between himself and Chu Jungui.
Chu Jungui didn't object, and took the initiative to name the strange beasts Thornback Beasts, locking them firmly within the crosshair range. Several spiny-backed beasts slowly climbed up the high slope and stopped at a distance of 1,100 meters. They also seemed to have discovered the embryonic camp, and there was a moment of confusion. Then they put their heads together and seemed to discuss something, then turned around together and aimed their butts at the base.
Chu Jungui felt a warning sign in his heart and shouted to be careful. He pulled Lin Xi and jumped off the roof of the cockpit and hid behind the bunker.
As soon as the two people jumped down, the longest thorns on the backs of the little beasts suddenly shot out, and the speed was extremely fast, almost passing over the top of the cockpit instantly!
The speed of these thorns has exceeded 500 meters per second. If Chu Jungui and Lin Xi dodge a little slower, they might be shot.
The little beasts immediately shot out the second and third thorns. Dozens of thorns flew toward the bunker with an ear-piercing whistling sound. Chu Jungui's heart trembled, but he still kept his body low, pulling Lin Xi back a step and leaving the bunker slightly.
Just a series of muffled sounds were heard as the thorns penetrated the mortar and bone plates, and the front end protruded more than half a meter long, trembling continuously. The longest thorn tip was only a few centimeters away from Chu Jungui's helmet.
