Chu Jungui was not far from the life-saving cabin, and quickly rushed to the side of the life-saving cabin. He opened the lid of the rescue chamber, pulled down the emergency breathing mask, and began to inhale oxygen. After a few minutes or so, he lowered his mask, coughed vigorously, and finally spat out a pool of yellow-green water.

Removing harmful substances from the lungs is an ability that every human who has completed basic survival training can have, it is just a matter of how much they can clean.

Of course, like Chu Jungui, who removes all the harmful substances containing sulfur in one go, is not something that can be achieved by basic survival training, and even advanced survival training is impossible.

After cleaning up his body, Chu Jungui thought about it, and still found a breathing mask, just took off the oxygen supply part and put it on his face. Although the mask does not supply oxygen, it has a filtering function that can filter out most of the harmful substances in the air. In this way, Chu Jungui will leave the rescue capsule for a longer time, at least for about half a day, before he needs to return to replace the filter.

It's just that there are still two pieces of filter stock, and then they will be out of stock.

Chu Jungui started the printer again, put all the remaining metal rods and carbon rods in, and then selected the primary refining machine on the blueprint. But there wasn't enough on-screen display material to print the entire refiner.

However, this is difficult for Chu Jungui, who has mastered the complete basic survival skill system, and he knows the structure of the refining machine well. He simply activated the printer's advanced editing function, modified the blueprint of the refiner, removed the hopper and grinding device at the inlet, and also removed the forming part of the outlet.

In this way, all that remains is the core component of the primary refiner, and the material used is greatly reduced.

The printer started again, and a few minutes later, the core part of the refining machine appeared in front of Chu Jungui. It is a machine the size of an ordinary microwave oven, with a multi-functional material separation furnace at its core. It is possible to switch between several modes depending on the feeding.

Chu Jungui rushed to the woods again, cut a tree trunk, took some strong acidic sap, and returned to the rescue cabin. He cut out a few planks from the wall of the tree and put them together as feed parts. A few more water cups and wooden troughs were dug with daggers as the outlet molding part.

As for grinding, he simply did it by hand, found two large stones, put the magnetine iron on the big stones, and smashed them all at once. The crushed powder is then mixed in the sap and placed in a refiner. Finally, a polymeric battery is inserted, which acts as power.

The refiner is a large energy consumer, and a high-energy polymerization battery can only support continuous work for an hour.

Chu Jungui started the refining machine, and after a while, he received two large cups full of basic industrial acid, mainly sulfuric acid. After extracting the acid from the feeding, he switched modes again, and a few more metal rods were added after a few moments, mainly iron.

Although these metal rods were a little rough, after Chu Jungui cut them with a dagger, they could barely be used on printers. With the materials, the first thing he did was, of course, to build the feed and outlet parts of the refinery, so that there would be a complete material refiner, and there would be no more trouble than now.

With the raw materials in place, the next step is to solve the problem of power source.

Fortunately, when deep space energy manufactures a general-purpose material printer, it fully considers the possibility of obtaining materials and the difficulty of processing, and also provides an ancient lead-acid battery blueprint in it. Chu Jungui already has sulfuric acid, and then as long as he finds some lead, he can make a battery.

Although lead-acid batteries are far less energy efficient than polymer batteries, the most important thing to survive on a strange planet is to solve the problem of existence first.

However, since pyrrhotite has been found, it is possible to find lead. Even if there is no lead, he can build a stellar energy board and charger first, and charge the two polymeric batteries for repeated use, which is just more troublesome.

Stellar energy boards are much easier, just find some stones on the spot and throw them into the refining machine, you can get a lot of silicon and aluminum, and then throw these materials into the printer, and in a few moments, Chu Jungui made four stellar energy boards, as well as a charger. After all of this, the polymeric batteries in the refiner and printer are reduced to a small half of the electricity.

"You want to survive with just a little supply?" Chu Jungui couldn't help but complain in his heart. But he also knows that every gram of weight he can carry in an escape pod is extremely valuable, and basic food and water must not be saved. Coupled with the printer itself, there is basically no extra weight quota.

At this moment, the storm has long since stopped, and the sun of this unknown planet is high in the sky, and the surrounding temperature has risen to 60 degrees under the sunlight. Fortunately, the travel clothes worn by Chu Jungui also have the function of a spacesuit, isolating the heat.

Chu Jungui spliced the stellar energy panels together, adjusted the angle so that it could receive sunlight to the maximum, and then connected the charger, put the two polymerization batteries into the charger, and went to explore the forest again.

This time, Chu Jungui went deeper, and went out to explore for a few kilometers before he began to return. His backpack was already stuffed with all sorts of harvests, a few barely edible tree fruits, two small beasts, and a bundle of sodium-rich plants. Then there is a barrel of sap.

But he still couldn't find a source of water.

In the forest, Chu Jungui used his arm shield as a shovel and dug ten meters into the ground, but he didn't see any water seeping out, but the soil became a little wet. During the excavation, he found that the roots of many large trees were unexpectedly deep. This meant that the depth of the underground water source was much deeper than expected, so he stopped digging and instead took a large vat of sap and brought it back.

By the time we returned to the rescue capsule, it was already getting dark.

Chu Jun leaned on the hull of the rescue cabin, built a fire pit with stones in the leeward place, and built a bonfire.

The climate of this planet is considered to be extreme among habitable planets, as soon as the sky is dark, the temperature begins to drop rapidly, and it is not long before it gets dark, there is already a slight chill.

But with a campfire, it's a lot more reassuring.

The polymerization battery has been fully charged, Chu Jungui has electricity in his hand, and he is not panicking. There was still a lot of base metal left, so he simply printed another iron grid, one at both ends, and put it on the campfire to become a grill. He skinned and deboned the three little beasts he had hunted, cleaned the entrails, and put them on the fire with iron sticks and roasted them.

After a while, the little beast was roasted brown. It's just that instead of a tangy fragrance, it has a spicy and pungent taste.

Chu Jungui tried to take a bite, his brows furrowed, and he almost spit it out. The meat tasted sour and astringent, with a burning sensation, which filled his mouth with hot pain.

The planet has an unusually high level of sulfur, and even the branches and trees contain a lot of sulfur. This little beast roasted on the fire is equivalent to smoking with sulfur smoke, and it tastes good, which is strange.

But if it's unpalatable, it's unpalatable, and this meat is still edible. The scan results showed that the content of fat, water or protein was not low. As for the smoked sulfur, such a little content can't help Chu Jungui's stomach. As an experimental subject, although Chu Jungui's body structure is no different from that of ordinary humans, the strength and function of each organ far exceed that of ordinary humans.

He frowned, gulped down the roast, and finally simply turned off the taste function for the time being, so as not to spit it out himself.

In the past, as an experimental subject, he would not vomit at all because of the unpleasant taste, but would only clean up because of the presence of toxic substances in his stomach. I want to vomit now, basically because of psychological factors.

Emotions began to affect the body, which seemed to be a new weakness of Chu Jungui, and it was also a shortcoming common to all human beings.

He didn't know if it was good or bad, but for now, it seemed that humans naturally had shortcomings of one kind or another, far less efficient and perfect than the test subjects.

A full five catties of barbecue meat were all under Chu Jungui's stomach in a blink of an eye. His powerful stomach crushed food and had a primary compression effect, so his abdomen was flat with only a slight bulge.

Chu Jungui patted his stomach, and could only say that he was barely half full. He needs a lot of energy to maintain the consumption of this body, and the minimum consumption is more than 15,000 kcal every day. Ordinary humans can only be compared to professionally trained athletes, or professional warriors who have completed a series of training in deep space.

He was a little annoyed, and it seemed that it would be better to use external energy sources directly than the complex and inefficient digestion process of humans. For example, if you make an interface on the body and insert a nuclear fusion battery, won't everything be solved?

But the mechanical structure of his body is actually pitiful. There are only a few data interfaces, and a few microchips scattered throughout the body, which are considered foreign implants.

In this era, all kinds of auxiliary chips have been widely popular in the middle and upper class human society, and there are many people at the bottom who can implant chips. In the field of chip design, manufacturing, and even maintenance and updating, there are several giants that have been entrenched for many years, and the scale is no worse than that of a giant like Deep Space Energy.

In a way, the total amount of implants in his body may not even be as good as that of a low-level worker.

I don't know what the person who created him had in mind to load him with such a small number of implants and replace them with powerful organs and muscles.

The next thing to solve the problem of food is water. Chu Jungui used the power of most of the polymer batteries as a price to use a refinery to decompose a barrel of tree sap into concentrated acid and pure water.

Although the separated pure water is only a large glass, it solves the urgent need. It's just that the energy consumption is a bit too much, and Chu Jungui's collection of solar energy for a day can only fully charge two batteries twice.
