Controlling the mecha to cast magic is a very challenging task. After getting through the initial inconvenience, Li Nan quickly entered the state. First of all, in order to be able to cast advanced magic more flexibly, it is necessary to make a thorough transformation of the mecha's hands. It is necessary to make it completely imitate all the movements of both hands.

Although the work is not large, it still surprised him by the drop from 45% to 28% after the transformation. Even the small mistake was quite incomprehensible. You know, it took more than ten days to go from 33% to 45%, and during this period, the function of the mecha hands was not missing at all! Now it has only increased a little flexibility, and it has actually washed nearly half of it!

Next, Li Nan tried to do anything with mechas, logging, mining, hunting, and refining. It took three days to build a tool that could barely be considered a ship. Because of the help of a small mistake, a lot of calculations and drawing calculations were omitted. And he also made great efforts for the boat as he wished. During this period, Xiaoying completed the amphibious transformation and began to try to dive in shallow seas to test the transformation effect while familiarizing himself with the environment.

During the period when he helped Xiaoying do the final test, Li Nan began to build a telescope for mecha. While correcting the material proportions to make the glass more transparent, he also conducted theoretical deductions with Xiaocuo.

"It turns out that the Fresnel lens you mentioned is this kind of concentric circle lens?" Xiaocuo began to draw a picture in the air: "If this concentric circle theory is refined to the nanoscale, the refraction effect will be stronger, and the distortion will be greatly reduced. We can use multiple structures to increase the observation distance. According to my analysis of the green star environment, if we accumulate the lens level to six layers, the telescope's observation range can be enhanced to 32 kilometers!"

Ah! Li Nan shook his head: "Scientist, your thinking is still too rigid! As the saying goes, how bold a person is and how productive the land is. You have to fully utilize your imagination! I thought back then, I only used five layers of lenses to easily achieve the effect of a hundred miles. When my light mirror technique and the Wizard's Eye upgraded a few levels, a thousand miles away would be no problem! According to you, the lens effect is better now, why has it retreated?"

Xiao Chou Review: "Sorry, my master, I still can't add magic factors to scientific algorithms. Unless I can fully grasp its secrets, data with too much ups and downs may cause my algorithm to collapse for me."

Li Nan smiled and said, "Don't count. Just do your part well. I'll be responsible for the magic part. Okay, remember to install those high-tech means of infrared analysis, radar warning, and enemy identification on the display screen. I'll be responsible for the production of mecha glasses."

After more than ten hours of hard work, when Xiaoying successfully dived a thousand meters and caught a sailfish alive, Li Nan independently designed and made the mecha with magic and high-tech pendant - mecha glasses. It was finally freshly released and passed the test! This mecha glasses, which were only 30 cm thick and much thinner than ordinary telescopes, had an effective detection distance of an astonishing 88 kilometers! This is because the mecha recognition system has too high requirements for the clarity of the field of vision.

The boat began to try to cruise the sea and make its first observation around the coastline. The little shadow also cruised in the near sea. In addition to scanning for underwater dangers, it was more important to conduct a submarine mineral search.

Three days later, Li Nan landed from another shallow 2,000 kilometers away, and Xiaoying also sent it back to the seabed mineral analysis report. Xiaocuo summarized all the data and started analysis.

"After sampling and analysis of seawater and seabed substances, the average value is obtained as follows. The strong dioxide content is 21%, and the metal content such as aluminum, iron, lithium, and copper is less than 7%. It can be concluded that the metals here have been mined! The content of calcium, sodium, and potassium is rare and there are almost no sulfides! Master, I can tell you very responsibly that this is a planet that was abandoned after being mined for important strategic resources!"

What? Li Nan and his friends were shocked by this scam conclusion at that time: "Why do you say that?"

"Master! According to the most common rules in the universe, a planet can enter the growth stage from the birth of single-celled organisms. Then gradually merge and evolve to emerge higher life. But all of this requires several indispensable and necessary conditions. First, suitable stellar radiation, which is what you call sunlight. If it is too far away, it will not meet the biological needs, and if it is too close, it will cause harm to the organisms because of the high temperature. Second, the planet itself must be in the evolutionary growth stage. The most basic manifestation is the earth

Volcanic eruption formed by nuclear fission. Among all lower civilizations, sulfur is the most basic strategic material. Although the strategic status of sulfur will decline after the level of civilization is increased. However, on a planet without higher civilization, all nature cannot capture the existence of sulfur! There is only one possibility in this situation, that is, this planet has been completely mined once! In the process of re-growth, sulfur is absorbed and transformed by natural laws, providing energy for the new core of life!”

Li Nan was a little confused: "What you mean is that there is life on this planet, which means it is still in its growth stage. The lack of sulfur in the surface elements is in conflict with this conclusion. So the conclusion is that this star has been over-mined and abandoned? Then the current situation is artificially created?"

Xiaochuang said: "Yes, master, you can understand it so much!"

Li Nan was ashamed: "No wonder I wanted to get a gun so hard, because I had this great killer weapon for energy conversion, so I didn't even pay attention to the basic ingredients for gunpowder. It turned out that the most sulphur element on earth was not here!"

If you think about it carefully, it is really terrifying. Almost all chemical reactions are more or less related to this thing. But there is no goods on Green Star! Now, it is no wonder that when they sent them to Green Star, they had to take off their clothes. It was not to embarrass the candidates or increase the difficulty, but some parts of this star are completely different from the earth! There is a lack of a necessary element in the chemical reaction, so it is impossible to invent hot weapons such as muskets. You can only continuously improve your cold weapons and your own abilities!

Li Nan, who understood the situation, was also startled and sweating. He could mine a planet three times larger than the earth and then transform it into a special assessment site. Such powerful moves are far beyond human imagination! But since they have such powerful abilities, why don’t they interfere in the affairs of the earth and use the most complicated means instead? Is there any unknown secret behind this?

Even if Li Nan was killed, he would not believe that the so-called high-civilization convention would take good care of low-level civilizations. The law of the jungle will never change because of the improvement of civilization level! Being beaten if you fall behind is a perfect axiom of universality! The reason why those second-level civilizations make them so obedient on the earth is definitely not because the humans on the earth are more peaceful and kind! In the eyes of the strong, these two substances are synonymous with snacks.

So, what exactly is the thing that can make higher civilizations worry about? Also, what is the "Cosmic Civilization Convention" that even doesn't even remember who he is, and is still obsessed with strictly guarding against it?

A small mistake reminder: "Master, the abandoned resource star has a very prominent feature, which is its stability! There will be no adverse conditions such as volcanic eruptions, earthquakes, tsunamis, etc. Generally speaking, the miner will wait until the environment here is restored before deciding on the next transformation intention. Generally speaking, the more suitable ones are livable or ecological tourism stars. In most cases, they will be abandoned and allowed to grow by the planet themselves."

Li Nan suddenly said the lich's words at that time, and subconsciously asked: "Will it be transformed into a prison or a place of exile?"

Xiao Chou replied: "Of course! However, in the Interstellar Convention, there are very strict restrictions on the exile and imprisonment of smart races. Generally speaking, exiled people have reproduced for generations. As long as they restore and improve their level of civilization, they can return to the civilized world and wash away the identity of prisoners!"

I understand! Li Nan suddenly realized that it seems that the situation on Earth is 80% like this! But, the dragon clan and the elves? Please, those two are immortal species. How come they become so depressed after reproduction on Earth for a while?

"Small mistake, do you know the Dragon Clan and the Elf Clan?"

"Yes, master! Those were the two most powerful races in the universe. Unfortunately, they fought each other endlessly because they were too powerful. Later, in a series of wars, they exhausted their resources and eventually died together! This is a well-known thing in the universe. After the decline of these two major races, the weak races that were initially enslaved by them were rebuilt after the war, and the most core technology also came from their ruins."

Ah? And this matter! Li Nan asked again: "How strong are the dragon clan and the elves when they were the most powerful?"

"In legend, the strong men of the Dragon Clan can cross the anti-space body, and easily smash the stars with a wave of their hands. The strong men of the Elf Clan can collapse the galaxy with one thought. But these are just legends. The specific real situation has long been annihilated in the distant river of history. After these two races that have been fighting forever, their inheritance and knowledge were merged by the original slaves to develop the current step-by-step universe civilization."

Li Nan secretly stumbled on himself, it seemed that there was an inside story here! In this way, the magic continent he was in during the two hundred years he traveled through time was true or false? And what about the obvious inheritance of the dragon and elves on the earth! Also, this little mistake, he was so busy asking for something else, why did he talk endlessly when he mentioned it, and he had no authority to ask for it? Wouldn't that mean that these knowledge is the most basic thing, but why, on earth, have never heard anyone mention it?

Before these questions were mentioned, a new situation appeared in front of us. Sixty kilometers ahead, a second "Dragon Mountain" was found!
