Knowing this most important plot element, the relationship between the entire plot will be solved. The reason why the "Destroyer Star" is to seal the "Gate of Hell" is obviously because the spores of ancient mold will erupt regularly from the Korra drill holes and then scatter to the world. These mold spores that have fallen into the ground and develop rapidly will trigger rounds of "destroying bacteria".

On the other hand, it is highly likely that only the ancient molds in the "Gate of Hell" have the ability to reproduce uninterrupted. Those spores scattered on the surface of the earth may lose their ability to reproduce after they grow into mold. Just like some social creatures, only the "Queen Ants" and "Queen Bee" have the right to reproduction. It is also similar to those of large mammals, only the strongest males have the right to mating.

Therefore, as long as the "Gate of Hell" is sealed at one time, this human catastrophe can be completely ended. As for the mold communities that have lost their ability to reproduce on the ground, it is enough to slowly remove them. Perhaps, this is possible.

"Okay, old man." This conversation allowed Wu Chen to know enough information.

"Young people, be sure to always pay attention to the air filter in your car." Seeing that the polar storm turned from weak to strong again, Dennis Tito's last advice was made before the satellite communication was interrupted.

"Okay, old man." Wu Chen nodded happily.

Air filter (Air Filter) refers to air filter devices, which are generally used for dustproofing in clean workshops, clean factories, laboratories and clean rooms, or electronic machinery and communication equipment, etc. There are models such as primary filters, medium filters, high-efficiency filters and sub-high-efficiency. Various models have different standards and usage performance.

Fungi is a kind of eukaryotic organism with "eukaryotic", "spore-producing" and "chloroplast-free". It includes molds, yeasts, fungi and other mushrooms known to humans. More than 120,000 fungi have been found. Fungi is independent of animals, plants and other eukaryotic organisms and forms a world of its own. The cells of fungi contain chitin, which can produce spores through asexual and sexual reproduction.

Generally speaking, the size of eukaryotic microorganisms is microns: mold 2 to 10 microns; fungi 2 to 30 microns, and the largest one can reach 100 microns is eukaryotic organisms, and the cell diameter is generally 10 to 100 microns.

For molds of 2 to 10 microns, it is enough to use a "medium-efficiency filter" that removes dust particles of ≥1.0 microns. Of course, to be safe, use a "sub-efficiency filter" that removes dust particles of ≥0.5 microns, or a "high-efficiency filter" that removes dust particles of ≥0.3 microns, or even a "ultra-efficiency filter" that removes dust particles of ≥0.1 microns. The higher the level, the better.

Dennis Tito reminded Wu Chen to always pay attention to the air filter on the car. Obviously, although the mold in the earth's environment cannot reproduce, it seems to infect humans.

Wu Chen did not scan the vehicle in this world, and did not know which air filter was used by people in the "Catastrophe" and which air filter element was used. However, as the "T815 Extreme War Truck" optimized by the "Machine Stirring", the self-purified air filter can be filtered to the nanoscale with the "Nanozoite nest". You should know that mold with 1 nanometer = 0.001 microns. 2 to 10 microns cannot penetrate at all. As for the nanometer mold on everyone's body, it is also impossible to penetrate.

Another more important thing is oxygen.

Wu Chen has asked the beautiful female soldiers to step up the preparation of liquid oxygen respiration tanks.

1 liter of liquid oxygen (≈1.143 kg), after gasification, it can produce about 850 liters of gaseous pure oxygen and 1 cubic meter (1000 liters) of pure oxygen. It can generally be used for about 11.5 hours to 14 hours under normal atmospheric pressure. This calculates that 1 liter of liquid oxygen can absorb 12 hours and can be used for 24 days (it is recommended that oxygen inhalation cannot exceed half an hour per day).

Moreover, excessive inhalation of 100% pure oxygen will cause harm to various systems of the human body, such as lungs, eyes, brain, etc. Inhalation of excessive pure oxygen in the human body will cause "oxygen poisoning", resulting in physiological dysfunction, damage to organ functions, and even death. Therefore, when using it, it is necessary to dilute the pure oxygen to about 21% before breathing normally. It is enough for each person to carry a 1-liter liquid oxygen tank. When breathing, use a nanosupply to filter the air in the environment and dilute it evenly before filling the forehead with the helmet.

Just imagine, Wu Chen can easily achieve it by rejuvenating and bringing back to life. It is not easy to fight against the "drug disaster".

As noon approached, the "T815 Extreme War Truck" arrived near the target point.

Human remains began to appear.

Many of these artificial objects that are obviously related to "space" come from the ISS International Space Station. After scanning, it was found that more artificial objects were frozen under thick ice.

"They said they had found several adventure teams before?" The large-scale spread of artificial objects made Valkyrie a little unbelievable: "It's too many."

"It's not just the legacy of several adventure teams. Perhaps from the "scattered days" at the beginning of the catastrophe, the coalition government that did not flee to space had tried to close the "Gate of Hell" more than once. The survivors of the ISS International Space Station just continued their previous plans after the demise of the coalition government." Wu Chen thought of a possibility: "General mold is afraid of high temperature, dryness, cold and low oxygen environments. It is also difficult to withstand the exposure of ultraviolet rays. Perhaps during that turbulent catastrophe, humans on Earth tried various ways to completely solve the bacterial disaster. The frozen man-made objects in front of them are the remains left by various attempts."

"If all attempts aim at the ‘Gate of Hell’, then the adults’ judgment on ‘spors flying’ must be accurate.” Valkyrie thought: “Only one ‘female strain’ has the ability to release spores.”

"Yes, Megan." Wu Chen nodded gently: "Try to scan artificial objects to find useful information."

This chapter is not over, please click on the next page to continue reading! "See the order, sir." Valkyrie took action immediately.

While driving towards the center point, the "T815 Extreme War Truck" scans the man-made objects scattered around as much as possible. Any recognizable text and graphics are accurately identified.

The fragmented information pieced together confirms Wu Chen's first judgment. Many of these artificial objects come from space. They are various scientific research instruments launched to the ground by the ISS International Space Station and even large remains of "return capsules". As for the astronauts inside, there is no trace of them. There is only one "trace" that can be identified and left like a shadow after being swallowed up.

The return capsule, which was torn in half by bare hands, was frozen in shallow layers several meters away from the wheel. If the nanocomposite armor was opened, it could be seen through the front windshield.

In other words, at a certain time very close to this day, the ISS International Space Station also tried to send personnel to Kolashenkong. As a result, while the plan was in progress, it was unfortunately infected and killed, and the corpse was not left alive.

The ubiquitous mold spores will reproduce rapidly in the host after infection.

As a type of fungus, mold is characterized by a relatively developed mycelium and no larger fruiting body. Like other fungi, it also has cell walls, parasitic or saprophytic survival. Some molds convert host tissue into toxic substances, while others may produce toxins, i.e. mycotoxins. This has great harm to human health, mainly manifested as chronic poisoning, carcinogenic, teratogenic, and mutagenic effects.

The first wave of reproduction can be completed in 7 to 8 hours. In a humid environment, it will double in about 20 minutes.
