Viruses and bacteria are not necessarily harmful, and a significant number of them are beneficial.

For example, endogenous retroviruses are beneficial to the human body and are an important basis for immune cells to produce antibodies.

There are many retroviruses that can be used as vectors for DNA recombination.

There is also the vaccinia virus, a virus that causes minor cowpox lesions in cattle. Smallpox was eradicated using the cowpox virus.

In addition to these beneficial viruses, there are more beneficial bacteria, such as bifidobacteria, lactic acid bacteria, yeast, etc., which are beneficial to people's life and health, and indirectly affect people's lifespan.

Therefore, a normal person is a mixture of human cells, viruses, and bacteria, and they are in a state of symbiosis with the entire human body.

So, this "longevity virus" may really make people live longer, at least theoretically......

What people are worried about is whether the rash introduction of this virus will cause genetic collapse, chromosomal aberrations and other diseases, after all, it is something on Mars!

This belongs to the "human genetic modification project", and the possibility of black shells is very high! Yu Yifeng and the experts are well aware of the risks. Isn't this how the Resident Evil and the loss of the virus in the movie were made?

So, like a chestnut in the fire, this is a thing where both risks and opportunities coexist......

Many big scientists, especially biologists, were excited, but they were also very calm, and they were a little worried in their hearts, and carefully inquired about the research team's research results, various data, and various experimental conclusions.

The discussion lasted for more than an hour, and the report was read several times.

It was only then that the big scientists said that there was basically no problem with the accuracy of the report, but there were many more data that had not been fully verified.

They believe that the basic principles of the long-lived virus have not yet been understood, the genetic sequence has not been measured, and there are still a lot of experiments to be done, because the genetic sequence of this virus is particularly complex, and it is impossible to achieve any results at least in the short term.

Seeing this, Yu Yifeng calmed down, of course he hoped that scientists could be more cautious. In fact, even if the scientists say that the sky is crazy, he will not rush to conduct human trials.

Who knows what the incubation period of this virus is? What if, after a few years, people get sick en masse? At the very least, you have to understand the working principle of the virus and conduct some animal sex tests before you can consider it.

Such caution is still necessary!

So in the following time, he focused on industry and biological sciences at the same time. Whether it's a perfection or a longevity virus, it's very important and can't be sloppy......

The machines roared, the motors roared, and the fully automated Kinov industrial plant was completed, finally showing its formidable industrial capabilities!

Many scientists and engineers shuddered, and were shocked and moved by the miracle they had created!

Ivanovich is in tears, this is the super industry he yearns for!

A mass-produced super excavator adopts unmanned means. After digging a wagon of ore, it is automatically transported to a place, where the ore is dumped on a conveyor track, which is then transported to the super train.

Finally, the super train transports the ore directly to the Noah. This series of processes does not require human labor and is done automatically by the program.

Unmanned driving is very convenient, one person can sit in the office and monitor a hundred units. These machines are basically error-free, and once there is an error, there will be a lot of feedback prompts, so that people have time to deal with it.

Excavators are spaced more than 300 meters apart, and if they are too close to each other due to a bug in the system or for some other reason, the alarm in the main control room will sound, and then the supervisor will operate it manually.

This kind of operation was a bit much at first, but then it came together in two or three days, and it became less and less.

Based on these errors, researchers analyze the specific causes and make improvements. With the update from generation to generation, there are fewer and fewer loopholes for unmanned driving......

People are also working on automatic maintenance machines, so that maintenance can also be done by machines.

A big problem is in front of Yu Yifeng, that is, the output of steel seems to be unable to keep up...... The fears of those smelters have come true!

In the beginning, people were working on procedures and building factories, and the consumption of resources was not large, and the steel production on the Noah was more than enough.

But now, the program has been studied, and the factory has begun to produce, excavators, trains, cutting machines, etc., all need a large amount of metal materials, so that the steel output on the Noah is not enough.

These super machines are too big, there are too many consumables, and a large number of material gaps are completely supported by inventory.

"Now there are only 1.3 million tons of steel in stock, which is only enough for a month and a half of consumption, which is too exaggerated, right?"

Yu Yifeng frowned and approved the construction of a steelmaking blast furnace.

This steelmaking blast furnace is a big one, 70 meters high! More than 6,000 tons of steel were used. Of course, it was built on the Noah.

In order to build this blast furnace, the engineers specially opened an unmanned room in the spacecraft. They took the lead in laying various pipes inside, such as raw material inlets, slag outlets, ventilation ports, and so on.

Then, people used various machinery to put the blast furnace together piece by piece, falcon jointing, seamless welding, etc., and it took about another month of work.

If it is officially operational, the production of this blast furnace will also be fully automated, and various conveyor tracks and robots will already be laid inside.

If it were in space, this blast furnace would definitely not be usable, and the main thing was heat dissipation. Its heat dissipation is too large, and using ice only lowers the temperature in the room, but it can't cool the inside.

If the huge heat can't be dissipated, the blast furnace gas pressure will get higher and higher, and it may explode!

But isn't it on Mars now, the temperature on Mars is more than 60 degrees below zero, and the atmosphere is relatively thin, but it is enough to have an atmosphere! More than a dozen exhaust fans continuously draw in cold air to dissipate heat and then exhaust hot air.

With such an air-cooling system, this blast furnace is barely usable.

Of course, there are no fossil fuels such as coal and oil on Mars, but some combustible ice such as methane has been found, mainly in the lower layers of several glacial lakes.

But people don't expect to make steel with carbon reduction at all, they still use electrolysis. According to this process, the refining method of iron and aluminum is similar, in which the minerals are melted into a liquid state and then electrolyzed.

The iron produced has a low carbon content, and after another set of procedures, it becomes a good crude steel.

Such blast furnaces consume a lot of electricity, and for this reason, people have built special nuclear power plants to supply electricity for blast furnaces. The high power consumption also contributes to a very high yield, which can produce 2,000 tons of steel a day and 600,000 tons a month! In other words, almost two steelmaking blast furnaces can make up for the gap in materials.
