By this time, both had not had a good rest for 20 hours. The test subject was fine, but Lin Xi gritted his teeth to support it. After several beast shocks, she also knew that she had to race against time now, and 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 reserves of mortar at hand, poured them all into the workbench, and began to manufacture biomass rifles.

A progress bar is displayed on the crafting table, and as you slowly walk to the end, the rifle icon turns green, indicating that it can be crafted. Chu Jungui also breathed a sigh of relief.

Biomass rifles have a wide range of raw material requirements, and although the composition of the mortar is complex, the physical properties after hardening are outstanding, which are not worse than ordinary composite materials, so they barely meet the production standards. This is also due to the high requirements for rifle barrels.

At this time, in the organic matter detector, the detection of the blood of the alien beast was finally completed. Chu Jungui got the report, quickly compared it with the database analysis, and then was pleased to find that as he expected, the blood composition of the alien beast was complex, which could meet most of the needs for the manufacture of biomass explosives, and the poor one or two components could most likely be obtained from the bones, if there were no bones, most of them would be in the soil or rocks.

The only fly in the ointment is that the blood content of the alien beast is extraordinarily small, only about one-tenth of that of a normal human of the same weight, and it is not known how they complete the circulation in their bodies.

Chu Jungui immediately nailed a wooden trough and wooden frame, hung several foreign beasts upside down on them at one time, and began to disassemble and cut. The animal blood is collected in a wooden trough and processed by an organic matter separator, which can be made directly into biomass explosives at the workbench.

As for both the cartridge case and the warhead, there are also solutions.

The strength of the alien beast bones is only slightly worse than that of traditional copper shells, but it already meets the most basic requirements, and it can be directly cut and processed. The warhead can be sharpened with animal teeth. The beast's sharp teeth are very heavy, and the density is comparable to that of steel, and they can be used directly as warheads after grinding.

In this way, Chu Jungui used the blood of the four alien beasts to produce about several kilograms of biomass explosives. The power of this explosive is far less than the advanced explosives used in survival rifles, so Chu Jungui set the charge of each bullet to reach 20 grams, so as to ensure that the initial velocity of the bullet is more than one kilometer per second. In terms of pure power, it is about the same as a 12.7 mm caliber machine gun from the industrial age of the parent planet.

Chu Jungui set up the production program of bullets on the workbench, and then put all the raw materials into it, and started the workbench. It's just that the electricity is not enough, and as soon as the base workbench is started, the portable refinery will not work.

After waiting for a while, the workbench discharge box sounded with a ding, Chu Jungui opened the discharge box, took out a freshly made bullet from it, and observed it carefully.

This bullet is slightly different from the blueprint, the shell is only faintly transparent, and the liquid charge inside is not pure green, but appears purple and turbid. The warhead still has bone lines and a heavy texture of metal.

As he was watching, another bullet fell into the discharge box. Chu Jungui silently calculated the time, about one bullet can be fired every 10 seconds, so that all the raw materials are consumed, and 400 bullets are produced, and the time is about an hour.

This production speed cannot be said to be satisfactory, but it is enough to solve the problem at hand, so Chu Jungui put down all other work, and the workbench is full of bullets.

Chu Jungui picked up the biomass rifle he had just made, loaded two bullets into it, aimed at a leaf petiole seven hundred meters away, and shot out with one shot.

The sound of the gunfire was a little dull, unlike the crisp and passionate of the survival rifle, and the trajectory of the bullet was not so straight, and it had drifted a little by the distance of five hundred meters. Although in the end, it was only 10 centimeters thick to hit the petiole accurately, but it was Chu Jungui's superb shooting skills and high eye-eye aiming accuracy, and the gun itself was still not good.

But I can't pick it now, it's good to use it.

Chu Jungui tried to shoot again, and he already roughly knew the data of this rifle and the bullets. After he fine-tuned the rifle, he handed it over to Lin Xi to familiarize himself with.

Lin Xi shot as soon as he received the gun, and the accuracy improved significantly after three shots. From this, it can be seen that she is also extremely talented in fighting.

With a rifle in hand, the two of them felt a lot more at ease. Chu Jungui continued to dispose of the corpses of the alien beasts, while Lin Xi hurried to get used to the control of the new rifle.

A rifle alone is obviously not enough, and the gun's combat effectiveness depends entirely on its accessories, at least for non-test subjects. Chu Jungui's eyes are equivalent to their own all-weather visible and non-visible light sights, and their hands are equivalent to the sum of stabilizers, grips and other messy accessories that increase stability, but Lin Xi does not have this condition.

Chu Jungui was dealing with the alien beasts and collecting materials, while thinking about what kind of accessories could maximize Lin Xi's combat effectiveness.

Just as he was thinking, suddenly several yellow signs appeared in his vision.

This is a warning that there is a possibility of danger, but it is still uncertain. But Chu Jun looked at it, although the speed of those signs was not fast, they all moved towards the base in an S-shape, and it was not very likely to say that there was no malicious intent.

Lin Xi also received the alert, she immediately returned, jumped on the roof of the cockpit, and looked into the distance, and now turned on the active scanning function of the warframe's environment.

Several strange creatures that slowly wriggled appeared in the field of vision of the two. Their heads are small and round, their eyes are squeezed into thin slits by flesh, their bodies are fat, full of horizontal flesh, their limbs are very short, and their short legs move happily, but not much faster. On their backs are more than a dozen sharp thorns of varying lengths, some of which are even longer than their bodies, and from a distance they look like they are covered with flags.

"It looks a little like a spinyback. Lin Xi said.

"I'm afraid it's not a good thing. ”

"Agreed. ”

"Go into a thousand meters and shoot. ”

"I opened fire at seven hundred meters. Lin Xi is now very clear about the gap between himself and Chu Jungui.

Chu Jungui did not object, and automatically named those strange beasts Thornback Beasts, and locked them firmly within the crosshairs. Several spinybacks slowly climbed the high slope and came to a stop at a distance of 1,100 meters. They also seemed to have spotted the embryonic camp, and there was a moment of confusion, and then their heads came together as if they were discussing something, and they all turned around and aimed their butts at the base.

Chu Jungui was alarmed, shouted carefully, pulled Lin Xi to jump off the cockpit roof, and hid behind the cover.

As soon as the two of them jumped down, the longest thorns on the backs of those little beasts suddenly shot out, and they were extremely fast, almost passing over the roof of the cockpit almost instantly!

These thorns have already exceeded 500 meters per second, and if Chu Jungui and Lin Xi dodge a little slowly, they will be shot.

The little beasts shot out the second and third thorns. Dozens of thorns flew towards the bunker with a piercing whistle. Chu Jungui's heart froze, his body still kept low, and he pulled Lin Xi to take a step back, leaving the cover slightly.

Only a series of muffled sounds were heard, and the spines pierced through the mortar and bone plates, and the front end protruded more than half a meter long, constantly trembling. The tip of the longest thorn was only a few centimeters away from Chu Jungui's helmet.
