A month passed quickly. The scientific investigation of Tep civilization has made preliminary progress.

"Is this civilization still using fossil fuels? "Popular Survey on Fossil Fuels", "Possibility Survey on Global Atmospheric Warming"..."

On this day, Zhang Yuan was sorting out this information in the captain's office, and all kinds of messy reports were included. He also heard the calls for people's tourism, including the topic of his own bionic transformation, which was raised again.

If robot VR technology is used for tourism, the effect will be much worse. It will take at least five years to replicate it in ten years. How can it be so fast? The weak body of humans cannot adapt to 3 times the gravity, and it is impossible to strengthen exercise. The only way to experience it personally is bionic transformation.

Of course, no matter how the people’s calls cannot be realized immediately. If you want to transform yourself, you have to go through some legal procedures.

Li Cheng of the Secretariat replied: "Part of it is used for fossil fuels, and the planet has very rich fossil resources. According to our geologists' estimates, it is at least 20 times that of the earth! Because the planet is large in size... and some of it is renewable biofuels."

"Oh? Biofuel?" Zhang Yuan said in confusion.

"Yes, this civilization generally cultivates an annual herb called "Alk", which can extract industrial alcohol and methane very simply and efficiently. Most of the fuel from airship engines is provided by this plant. Only a small amount of military weapons, which require high-calorie fuel, can use oil."

"It's really a very good plant. This was an unexpected surprise."

Many chemical raw materials in Kunlun Mountain are also provided by plants, so the biologists of Kunlun Mountain are thinking that if this plant is indeed very excellent, they can try to introduce it into the entire industrial system.

Zhang Yuan thought for a while and frowned and asked, "Did the Taipu civilization consider renewable energy so early? They are so far-sighted? But when the oil crisis really happened, humans vigorously developed controlled nuclear fusion. Most of the oil was simply burned. Is there a deeper reason, for example..."

"Not that, it's mainly economic reasons." Dr. Li Cheng said with a smile: "Because for this civilization, although there is oil, it is too difficult to dig. In high gravity environments, the shallow surface oil is very scarce, and it requires greater pressure to be mined. Oil mining depends on the artificial supplementary energy such as oil pumps and gas lifts, which is more difficult in high gravity environments."

“High-quality oil is on the deeper surface, resulting in high mining costs.”

This is true. In high gravity environments, the deeper surfaces are harder, and it is more difficult to extract oil.

Just like the earth's shale oil reserves, with a reserve of about 11 trillion to 13 trillion tons, far exceeding the oil reserves, but it is extremely difficult to develop, and only a small part of it can be used.

Dr. Li Cheng continued: "The planet is vast and sparsely populated, with a surface area of ​​four or five times that of the earth. The population is not high, about 4 billion. Therefore, these farmers choose to plant this type of plant on a large scale in plains, which is economical and affordable."

"So that's it." Zhang Yuan asked when he heard this: "So do you think this excellent energy plant was deliberately left by the enlightener civilization? Oil will be used up no matter how many of it is, but renewable energy is completely different and can continue for a long time."

Looking for traces of enlightener civilization has always been the key goal of human beings' scientific expedition. People have been looking for so-called evidence. It is impossible for any storm or coincidence to think that it was left by enlightener civilization, which is too funny.

Faced with Zhang Yuan's question, Li Cheng replied: "It depends on the time point '150,000 years ago', whether this plant called 'Alk' has undergone large-scale genetic mutations like the 'World Tree' of the Riley civilization. If so, it can basically be concluded that it is the act of the enlightener civilization."

"...This civilization analyzes from an innate perspective. It is indeed very difficult to enter space. If controllable nuclear fusion cannot be done, even if there is no energy crisis now, there will be a future."

"The energy crisis will undoubtedly greatly alleviate this plant now, and it can provide more time to develop."

Zhang Yuan nodded and said, "However, this does not seem to be in line with the concept of enlightener civilization. If this civilization gradually stops progressing in the next few thousand years and continues to use this plant to survive, wouldn't it be the same as the Riley civilization? What's the point of continuing forever? So I think, for this reason, the probability of deliberately creating this plant is not high."

"According to my personal opinion: if a civilization runs out of fossil fuel but does not ignite the spark of nuclear fusion and leaves the planet, then he will die, and there is nothing to regret."

Li Cheng replied: "I don't agree with your idea very much. I think it needs to be considered from the technical difficulty of leaving the planet itself. If the gravity of a planet is ten times that of the earth, can the creatures of this planet leave the planet? It is impossible, even our spacecraft will find it difficult to take off and land. Then the appearance of an energy thing that allows these lives to breathe can be considered a kind of kindness."

"Our scientists are deducing whether it is possible to leave a planet with three times the gravity and start the interstellar era if it develops step by step according to the technological level of mankind at the end of the 20th century."

"Related mathematical modeling work is still in progress. Some scientists think it is OK, and some scientists think that traditional rocket technology is difficult to help the Tep people leave the planet step by step."

"If it really doesn't work, it means that the innate environment of this civilization has defects and requires some help. The foresighted enlightener civilization may try to do something in this regard..."

"This idea makes sense." Zhang Yuan saw a photo on the screen, and human research scientists were visiting the museum.

This civilization also has its own archaeology and is also studying its own origins. This may be the common point of scientific and technological thinking. Everything wants to trace the origin, rather than ignoring its existence to the gods in a confused way.

Therefore, the current research direction is divided into two parts, one is archaeology, focusing on the history 150,000 years ago.

Another part is to examine whether the Taipu civilization has technological defects, environmental defects, whether there are hidden help from enlighteners, etc.

"There is no particularly good discovery yet... In 150,000 years, a series of complex evolutions have been formed. If we do not rely on the power of the Tep civilization itself, it will be too slow to let our own scientific research."

"Our diplomatic team is considering whether we can directly make such scientific research requests to the other party. Or, it would be better if we could directly read the other party's archaeological documents... After all, the other party's information has not been completely disclosed to us."
