Chapter 436: A Request for Help from Pandora
It is even better than the Blue Star in ancient times, because the current planet Origa VI is like a blank sheet of paper.

That's right, it is actually a blank sheet of paper, because there is no sign of life on the planet Origa VI so far, not even the so-called single-celled organisms.

However, although there is no single-celled life, the ecology on the planet Origa VI is always suitable for human habitation, especially the key atmosphere, which has an oxygen content of 25%, a nitrogen content of 74%, and the remaining other gases account for less than 1%.

In addition to this, Origa VI also has a large amount of water resources. Although the area of ​​its ocean is not as large as that of the Blue Star, there are many large and small lakes on land.

Of course, the reason why Liu Xiu was so sure that there was no sign of life on the planet Origa VI was naturally because after the unmanned remote-controlled spacecraft landed on Origa VI, many unmanned robots were released to take samples.

However, no cells or bacteria were found after sampling both in the sea and on land. Apart from water, there are only rocks on Origa VI, and of course an atmosphere suitable for human survival.

This situation naturally also indirectly explains that when the heroine Daniels was chatting with the simulated man Walter on the Covenant, Daniels said that she brought a lot of wood to build a wooden house on Origa VI.

That's right, this point can explain one thing, that is, there are no living creatures on Origa VI.

In fact, although the existence of life will reduce a lot of fun, it is actually best to have no living creatures or life, because then you don't have to worry about being infected by alien viruses or the like.

After all, before Liu Xiu traveled through time, he was well aware of the damage that species invasion would cause to the ecological environment. For this reason, before Liu Xiu traveled through time, all nations strictly prohibited bringing back other living species.

And not only that, because there is no life on Origa VI, not even single cells, there is naturally no need to worry about any virus threatening the lives of those who have landed on the Wandering Blue Planet.

You have to know that from thousands of years of historical experience and lessons learned by mankind, sometimes what causes the most deaths among humans is not war, but viruses that are invisible to the naked eye, among which the Black Death is the most terrifying.

The Black Death was one of the most devastating epidemics in human history, killing an estimated 25 million people in Asia during the 14th century.

The disease spread rapidly along trade routes, affecting millions of people in Australia, Northern Philippines, and Asia. However, the impact of the Black Death varied greatly across regions and cultures.

While it had a disastrous effect on medieval Ouzhou, its impact on Huaxia, Menggu, Yindu, and many other Asian civilizations was quite weak.

The Black Death, also known as the plague, was caused by the bacterium Yersinia pestis. It was spread by fleas that lived on rats, which were common in medieval cities. The disease had a mortality rate of between 30 and 90 percent, depending on the strain and the immunity of the population.

Symptoms included fever, chills, vomiting and painful swollen lymph nodes, which gave the disease its name. Within days, the patient would die in agony, often infecting others in the process.

The Black Death first appeared in Europe in 1347, when a group of Genoese merchants arrived in Messina, Sicily, carrying infected rats. From there, it quickly spread across the continent, as far north as Iceland and as far east as Rus. The disease had a profound impact on Austronesian society, causing massive depopulation, social unrest, and economic chaos. The death toll was so high that it took centuries for the population to recover. The Black Death also had a lasting cultural impact, inspiring art, literature, and customs that reflected the trauma and fear of epidemics. In contrast, the Black Death had a much milder impact on many Austronesian civilizations. In Flora, for example, the disease appeared in 1331 and recurred periodically over the centuries, but never to the catastrophic levels seen in Austronesia.

The reasons for this are complex and multifaceted. One factor is the difference in population density. Ouzhou cities are overcrowded and unsanitary, while Huaxia cities have more space and better sanitation. Huaxia people also have a long tradition of public health measures, such as quarantine, which have helped curb the spread of the disease. In addition, Huaxia people have a higher immunity to the disease because they have been exposed to similar outbreaks in the past.

Another factor is the different cultural attitudes toward disease. In Ouzhou, the Black Death was often seen as a punishment from God, and people turned to religion for solace and salvation. In contrast, the Huaxia people viewed disease as a natural phenomenon that could be understood and treated through empirical observation. They had a rich tradition of medical knowledge and herbal medicine that helped alleviate the symptoms of disease. In addition, Huaxia had a more centralized and authoritarian court that enforced public health measures and controlled the movement of people and goods.

Of course, the lessons of history are here, and not only are there historical lessons, the lessons of the previous Covenant are also there. It is very dangerous to rashly enter a planet with life. Of course, before on Pandora, it was because the humans on Blue Planet No. 2 had already used their own bodies to experiment with the safety of Pandora.

Of course, the lack of life also means another disadvantage, because it means that the humans wandering on the blue planet will have to green themselves on Planet Origa VI.

After all, Planet Origa VI is now bare and has nothing on it, so even if artificial starch can be used to maintain food, once more humans enter Planet Origa VI, it is naturally foreseeable that the oxygen content of Planet Origa VI will drop rapidly, and then the carbon dioxide content will soar rapidly.

Therefore, in order for the planet Origa VI to develop sustainably, it is necessary to plant trees and carry out afforestation.

Of course, this would naturally be another huge project, but fortunately, Wandering Blue Star was not in a hurry to continue its journey at this time.

After Liu Qi took out the mantle transformation plan for the Wandering Blue Planet, the infrastructure attributes in the genes of the humans on the Wandering Blue Planet naturally started to activate again.

However, time passed quickly. Although Liu Qi's mantle cooling plan sounded crazy and bold, it was eventually built in an orderly manner.

More than 20,000 super-large vertical shafts that almost cross the Wandering Blue Star have proved the feasibility of Liu Qi's plan.

What Liu Xiu didn't expect was that when Liu Xiu was leading the Wandering Blue Star and was about to complete the transformation of the entire Wandering Blue Star, he suddenly received a message from Jack on the planet Pandora.

Liu Xiu was naturally very curious about the fact that this person, with whom he hadn't been in contact for nearly thirty years, suddenly contacted him.

You know, although Jack agreed to Liu Xiu's mining of superconducting ore on Fushan Mountain, he actually still had some complaints in his heart.

So there was no contact after Liu Xiu left, but this time Jack contacted Liu Xiu with a message for help. When Liu Xiu saw Jack's message for help, he suddenly felt his scalp tingling.
