Chapter 389

When the spittle of these experts flew, Li Zhendong, an informatics expert, stood up and expressed his unique opinions.

"Don't get too excited, professor. Why do I have a little doubt, enlightener civilization, just this name for the time being... Is it really a civilization full of goodwill? "

He spread his hands and questioned: "Riley civilization is a very ancient religious civilization. A brilliant culture, including words and language, was born millions of years ago. It has been stagnant for a long time and has been in a stable state. If it goes on like this, there is likely to be no progress. But the enlightener civilization planted the 'World Tree'. What is this for? Can it promote the development of Riley civilization? "

"You know, this species can trigger a mass extinction!"

"I even feel that we have over interpreted the incident. The enlightener just wants to use the world tree to turn all the carbon elements of the planet into this organic matter similar to coal, and then harvest it at one time. "

"We already have relevant cosmic knowledge. Organic matter is more valuable than ordinary metals in the trading market! For more advanced civilizations, as long as the core resources can be exploited, metal elements are completely inexhaustible, including various rare earth elements, which can be found everywhere in the depths of the core. But organic matter is different. There is only a thin layer on the surface of the planet. There is no need for more! "

"Using such biotechnology to collect organic matter is more cost-effective and more effective!"

He said with great emotion: "it's really a big deal. It's a big deal to harvest a planet at one time! Maybe it's not just this one, but... Countless planets! Including the former earth, but the plan on earth may not succeed. "

There will be a moment and a half of silence in the conference room. Zhang Yuan even felt his hair stand up, from good to evil, as if it was just a moment's effort.

Soon, Li Zhendong's conjecture triggered a big wave!

People think that if this civilization is really "evil", then

Have they done anything to mankind and the earth?

There will be a terrible silence in the conference room for a moment and a half.

The biologist hesitated and explained, "I still feel that the enlightener civilization is full of goodwill to Riley civilization. Professor Li, if you want to implement this plan that lasts for millions or even tens of millions of years, you should choose a planet rich in carbon for experiments? "

Li Zhendong nodded, "indeed... The starting point is very important."

The biologist continued: "however, the carbon content of Riley is not high, just a little more than that of the earth. According to you, you should choose a planet similar to Venus with all carbon dioxide on the surface, so as to maximize the benefits. Why did the enlightener choose Riley? It's not worth it! "

Li Zhendong reddened his neck and said loudly, "they may have arranged countless planets. There is no need to consider whether it is cost-effective or not. It's like we use a large planter to sow in the field. It doesn't matter whether the seed can germinate or not, as long as it can grow plants. It doesn't matter if the harvest is less. Will you think about the harvest of a certain wheat? "

"But why hasn't the earth been harvested? And Venus, Mars! "

"Because this plan can't be 100% successful. Have alien species been eliminated by native species? Or is it a climate disaster that wiped out alien species! Oh, by the way, don't you think the evolution of life in Australia is very strange? Maybe aliens did it? " Li Zhendong's brain hole is wide open.

"Professor Li, an Australian species, has fossils millions of years ago. The time node is not right."

Just as the two people were arguing over this, Zhang Yuan suddenly said, "listen to me first. First of all, if the civilization that transformed the world tree is really the 'enlightener civilization' encountered by Gliese civilization, there will be no great malice from their actions."

"Because Gliese civilization has clear written records, the enlighteners let them know the existence of science and electricity."

"Secondly, if you want to use biotechnology to fix carbon and use microorganisms with the strongest reproductive ability, such as algae, is it much more efficient than the world tree?"

"If this civilization is indeed strong enough, it should not be a problem to develop such microorganisms, rather than such tall plants as the world tree. Although the final effect is the same, there is no doubt that the efficiency is more than a little lower."

Li Zhendong was thoughtful and didn't speak, which is difficult to explain. If it is forcibly determined that a higher civilization cannot develop such microorganisms, it will only make people laugh, and even he doesn't believe it.

Everyone gradually calmed down and breathed a little relieved.

If an interstellar civilization wants to mine materials, there is no need to modify the genes of local species according to local conditions.

"If it has great malice, it can directly develop one or more super microorganisms, eliminate all animals and plants, and then reproduce without restriction. The Riley people don't have to let them live. They make variables in vain. "

In this way, the efficiency is tens of thousands of times higher than the simple world tree. The species extinction plan that the world tree can complete in tens of millions of years, using super microorganisms, can be completed in hundreds of years

Zhang Yuan added: "actually, everyone, think about it carefully. I still think the enlightener has a certain goodwill. The world tree in this world is not necessarily bad for Riley civilization. "

"First, the world tree provides a lot of food and living space. At least in ancient times, there was a shelter from the wind and rain, and the possibility of starvation and freezing to death was much less. Without the world tree, their population would be much smaller, and the development of civilization would be more difficult. Where would it be so comfortable now? "

"Second, the world tree provides very good building materials. The performance of this tree core is comparable to that of steel bars in the 20th century, and it is not easy to rot and be oxidized by air. This biomaterial can still be used in the 20th or 21st century! "

"It should not be difficult to understand how much convenience this will bring to development. In terms of infrastructure and building houses, even steel bars can be saved."

Many people nodded. When civilization was underdeveloped, there was a high-performance material that could replace steel, which was a great advantage.

Steel is the cornerstone of civilization and industrialization. The industrial process of almost all industrialized countries begins with the large-scale steelmaking. Without steel, there will be no other industrial products, no high-rise buildings, no guns, vehicles and ships.

If "steel" can grow in the field in the early stage of civilization development, its convenience is of course self-evident.

"Oh, yes, and the third point, because the emergence of the world tree has fixed more carbon elements, and there are more fossil resources in the whole world! If Riley civilization really developed modern science and technology, it will thank these fossil resources. Who doesn't want to have more fossil fuels in the early stage of civilization? "

"This is a great gift from heaven. Can the earth civilization develop modern civilization without fossil fuels? No! Even the first industrial revolution could not be produced! "
