"Gold, Rainbow Coins, Liquid Silver Coins, Folded Obsidian Coins...... All countries in the universe use the same monetary system, and no matter what the coins look like, the exchange system is the same......"

"The gold coin represents the pursuit of wealth in the primeval times of mankind, and the heart is used by the lowest ordinary people...... The other three currencies represent the core technology of human exploration of the universe, the space folding engine......"

"The invention of the space folding engine is inseparable from three strange minerals, colored red crystal, liquid mythril and folded obsidian, three basic minerals are indispensable, and it is precisely because of their preciousness that they have been made into monetary ...... by humans."

"Ahh It's so difficult, why do I have to memorize this bitter and difficult historical knowledge? I'm a closed disciple, and I don't have to take the exam, isn't it embarrassing for the master! ”

Li Mi had just challenged a 170-metre-deep high-pressure training session in the Coral Sea, and in between breaks he began to look through the history textbooks given to him by Truss.

It has been half a month since he came out of the hospital, and Li Mi and the third class have not received any tasks, during this time, Li Mi is desperately carrying out deep-sea pressurization training, while the other brothers in the third class are gathered together by the military department for training.

The third squad will soon become Mr. Truss's personal guards, although they are very proficient in security processes, but just in case, everyone still has to carry out assault training, updated equipment, updated security thinking, and more coordinated combat cooperation.

They even had to train on all kinds of equipment, and I heard that Liu Bo would give them a training warship in the future so that they could learn to drive.

The bloody sacrifice of the third squad finally paid off, although they still wore the hat of auxiliaries, but in the eyes of the military department, the third squad was already an elite special forces sequence, and now even the battalion commander of Chester could not order them.

Li Mi has never been afraid of pain in martial arts training, but Li Mi is too bad at reciting boring historical knowledge, he has not received higher education since he was a child, and he must start learning from the most basic knowledge.

How did humans invent the space folding engine, how did they explore the dark sky, and why couldn't the most primitive chemical rockets travel to the stars? These junior high school students have already understood the knowledge, and Li Mi must start from scratch.

Lying on the beach, the warm sun is shining on you, a few hermit crabs are crawling on the sand, the blue waves are crashing against the shore, surfers are screaming excitedly in the distance, and white fishing boats are returning with full loads.

From time to time, a beautiful ** girl walked past Li Mi, and her hot eyes roamed on Li Mi's strong muscles, but fortunately, Li Mi was wearing a big pair of sunglasses, so the girls didn't recognize who he was.

If they knew that this sturdy man lying on the beach reading was the big hero Li Mi, I think a few bikinis would suddenly fly on the big hero's face, and the hot ** would definitely throw himself into his arms.

Li Mi, who has seen Princess Hanyu**, already has absolute resistance to beauties, and all the girls on the beach, even those who are sunbathing in celestial bodies, none of them can compare to Princess Hanyu.

With the princess's pot of wine at the bottom, other beauties naturally couldn't get into his eyes, and with a sigh, Li Mi paid attention to the teaching materials again.

"Human research on space folding engines originated from the scientific research of scientists in ancient times on dark canopies...... At that time, the dark canopy had another name, called dark matter......"

"Dark matter! Dark matter? What an obscure term, meaning dark matter? It's so sad......"

Just when Li Mi gritted his teeth and fought against these ancient historical knowledge, suddenly a burst of shade blocked the sunlight, and a head with a big straw hat appeared in front of Li Mi.

Her long wavy hair was draped over her shoulders, and her huge sunglasses covered half of her face, but Li Mi recognized who she was with just one glance at her mouth and nose.

"The big reporter didn't go to interview today, why did he have time to come to me? Say, what are you hungry for, I'll make you ......"

Lan Xin gave him a kick, "Can't I take a vacation?" You think I don't know how to cook? Don't underestimate people......"

"Don't don't, don't blow your cooking skills, you can make noodles paste the pot, and I'm convinced of you......" Li Mi's words provoked Lan Xin to kick a few more times.

At this time, Li Mi saw the clothes Lan Xin was wearing today, a floral long skirt that dragged to her feet, but there was only a bandeau on her upper body, and the straw hat woven by precious jade grass exuded a faint fragrance, mixed with the fragrance of a woman's virgin, which made Li Mi's heart secretly angry.

"Ahem, ahem...... Don't kick, I just took a 170-meter deep dive, my muscles are sore, and you raised me after kicking my broken leg? ”

The atmosphere in the air suddenly became ambiguous, and the sentence "You raised me" made Lan Xin's face suddenly red, "You can't eat much, I can afford to raise ......"

These words came out of Lan Xin's mouth, and I don't know how many men's hearts that I had a crush on him would be broken.

Li Mi didn't dare to answer this, and quickly pulled out an incubator from behind him, and after opening it, it was filled with cold beer and purified water, "Hmm...... What do you drink? ”

Lan Xin gave him another kick of "wine!" I want to see if I'm drunk and if there are any hooligans bullying me......"

Li Mi is so angry in his heart, can he still have a good chat? Don't let people talk? How did Lan Xin suddenly become more open and spicy after the last catastrophe?

"What are you looking at? Ay...... Isn't this the general history of the universe annotated by Truss? It seems that you have really become a beginner disciple of Mr. Truss, and you are so lucky that you are ...... against the sky."

"Do you understand? You've seen the dark canopy, huh? Let me, the teacher, tell you about it......" After speaking, Lan Xin sat cross-legged beside Li Mi, and the proud mountain peak was close at hand, and she was almost about to rub against Li Mi's body.

Li Mi sighed in his heart, when he met such a hot teacher, what kind of student could he listen to the lecture well?

"When human beings did not leave the cradle home planet, the exploration of the universe was very superficial, with chemical rockets with limited functions flying satellites in space, and various primitive telescopes bringing images of the universe...... And more often than not, the universe as it really is only in the mathematician's model......"

"Dark matter is a substance smaller than electrons and photons, has no electric charge, does not interfere with electrons, can pass through electromagnetic waves and gravitational fields, and is an important part of the universe."

"Dark matter is very dense but in large quantities, so its total mass is large, and they represent 84 in the universe. 5% substance content...... Listen, such a large amount of dark matter is the basic material that makes up the dark canopy......"

"The dark canopy occupies most of the space of the cosmic consciousness, and the human eye can't see it at all, and other equipment can't detect them except the canopy radar, and these clouds of dark matter gathered together are the dark canopy, the forbidden place of space navigation......"

"Through the study of dark matter, mankind has discovered three epoch-making precious deposits: colored red crystal, liquid mythril and folded obsidian......

"With the space folding engine, mankind has officially entered the era of space development, and a space folding is a few light years or even more than ten light years, and the era of great exploration and migration has begun......"

"But as the footsteps of human beings go farther and farther, the phenomenon of mysterious disappearances of spaceships will become more and more, and later people will learn that there is still an unknown and mysterious place in the universe, that is, the dark canopy ......"

"The dark matter and dark energy in this are hundreds of times more explosive than in other places, and no matter how safe the space folding engine enters the sky, there will also be power disorders, obviously it can travel ten light years at a time, but it can only travel two or three light years in the canopy......"

"Not only that, but the explosive energy in the canopy will also interfere with all electronic devices, and the spaceship will immediately become blind and deaf when it enters the dark canopy, and eventually lose its way and become a ghost ship in the universe......"

Lan Xin is really a gold medal reporter, her eloquence is good, and her profound knowledge makes her clear and thorough in a few words.

"Ahh I finally understood, no wonder some people say that galaxies are like land, and the dark canopy is like those raging oceans that divide land, and the space passage is a land bridge......"

"That's right, the children can be taught! The dark canopy divides the galaxy into enclaves, which are completely connected to each other by spatial passages, which are strategic points that humans have explored from the canopy, and are the only safe passages......"

With a snap, Li Mi slapped his thigh, "That's right, that's right, so all countries are desperately guarding these space passages, because they know that no enemy country can attack from the dark sky, and the battle for space passages is the only choice!" ”

Li Mi scratched his head, "It would be nice if all the teachers were like you......"

Lan Xin gave him a blank look, "If all the teachers are as beautiful as me, do you bad students still have the heart to study?" ”

Li Mi was speechless, he found that Lan Xin had become more and more bold, and he couldn't say three words in front of her and always lost.

"Okay, that's all for the history of dark matter and the dark canopy...... In fact, I came here this time because I was entrusted by someone, and there is a person who wants to invite you to dinner and wants to have a relationship with you......"

"Who?" Li Mi asked puzzledly, "I'm not a big person, who will ask me to pull a relationship?" ”

After a while, Qin Le's figure walked over from the parking lot, and Qin Le's hands stretched out from a long distance, he grabbed Li Mi's hand and shook it desperately, "Mr. Li Mi, I haven't seen you for a long time, please forgive me for my presumptuousness, to be honest, I really don't know who to ask for, I can only trouble Miss Lan Xin...... I hope you can give me some thin noodles, I have prepared a table of wine and food at the Antelope Bay Hotel, and I hope to enjoy the light, enjoy the light! ”

Li Mi looked at the embarrassed Lan Xin and sighed, "Hey...... I'm not a high-ranking official, so why are you so polite? ”

"Brother Mi, what are you talking about? Mr. Truss's closed disciple, the Hebrew apprentice of the King of Soldiers, your identity is in Hua Hanxing, and you are also a big man respected by everyone, and it is really too humble to be too modest......"
