I said, "No cruel orcs will ......"

Leo said: "Yes, yes, you will disembowel, break the soil and chop it into minced meat, but you will not carefully cut it, and figure out the ins and outs of breathing, heartbeat and pulse, not to mention orcs, it is estimated that elves and humans will not do this, the main thing is that they don't have a concept, after all, it's too evil, but I've also said it countless times, if you can unravel the principle of disease for more people and help more people, what's wrong with doing this......"

I kind of understood: "After the dissection, you will understand the principle of the disease......

Leo said: "It's not that simple, but the progress is obvious, in ancient times, human beings could only rely on all kinds of strange herbs, strange treatments, turn to wizards or clergy, unfortunately, our clergy do not have the ability of yours, at this point, your medical treatment wins." ”

I was a little proud, and Leo poured another basin of cold water: "However, your priests are too few, and the cost of treatment is too high, which is not as popular as ours, and our medical treatment has greatly improved the chances of survival and increased lifespan." ”

"Boost life?" My eyes widened.

"Don't get excited," Leo said, "in fact, the effect is not as strong as the elemental energy and anger, and besides, it is only from forty or fifty years old to seventy or eighty years old, and the old ones will still be old, unlike you, who are still young like children in their seventies and eighties......

He was talking about the high priest Dragongar.

In fact, most priests and angry warriors have this trait—they age a little slower than the average person.

I said, "What about the specific treatment?" ”

Leo said: "The main thing is to take drugs and direct transformation, the drug is more complex than your herbal medicine, this will be said later, the transformation is more powerful, the simple point is corrected with instruments, and the serious direct surgery ......"

The man in the picture is pierced through the abdomen by a sharp breath and begins to bleed, and a group of people who resemble scientists suddenly appear and begin to treat his injuries.

Next, it's a little shocking -

They cut open the abdomen of the wounded, took out sharps, then cleaned the damaged internal organs, stitched up the wound, and then, the wounded lay down for a while, and it was fine!

Leo saw my surprise and doubts, and immediately explained: "Don't think it's okay to pull it out and sew it up, there are many details in it, first of all, the surgery must be absolutely clean, because there are microorganisms in the surrounding air, they will invade the human body and cause infection, killing people, so, there are many means to ensure that the wound is absolutely clean, secondly, there are many instruments to maintain the breathing blood flow and pulse of the injured person, when necessary, there is also a backup blood supplement, during the recovery period, there are various drugs to ensure wound healing, by the way, the most critical, During the operation, there are anesthetics that make the injured unconscious and not feel pain, and when it comes to surgery, I can't write a hundred books to talk about a small part of it......"

I could hear it.

Although this operation is very troublesome, and there is no cure at all, the whole process can be completed even by ordinary people!

Leo felt that my gaze was a little hot, and began to pour cold water again: "These doctors are also trained for a long time, although they don't need to feel any talent, but there are not many people who can become doctors......"

"You don't have to explain......," I said, "I understand, but our world really needs ......."

Leo smiled: "Don't worry, there will be, and besides, the earth's modern medicine plus your healing technique will have an even more amazing effect!" ”

I was a little excited, not particularly strongly, but it also made me jot down more notes.

"It's just a concept of medicine, and I'......ll talk about it later," Leo said, "and then talk about the military ...... you're most looking forward to."

If human medical care makes me envious, human military makes me shudder!

Not to mention the guns that have already been seen, but the so-called "nuclear threat", perhaps, gathering all the priests of the orc race to attack together will not achieve the effect of a nuclear bomb.

Moreover, there are thousands of such weapons in humans!

It is no wonder that the humans of Earth choose to coexist peacefully......

Once such a weapon is launched, both sides, that is, the whole of humanity and the whole earth, will be destroyed!

Speaking of which, the appearance of peace on Earth is not much better than that of Santas......

I also wrote more than half of the second notebook, but I was a little unsatisfied.

"How much more hasn't been said?" I asked.

Leo was stunned for a moment and said: "Actually, I don't know myself, some industries, some can't be touched in a lifetime, then you can only meet and talk about it, or you can talk about it, what else are you interested in?" ”

I thought about it for a moment, but I didn't know what to say.

It's not that I can't think of it, it's that I have so many questions that I don't know where to start.

"Hmm......," I thought for a moment, flipped through my notes, and said, "Like, how do you do ten people to work for ninety people?" ”

Leo opened his mouth as if he was inspired: "Modern agriculture!" From the cultivation of the seeds to the harvesting, they are precisely calculated and designed, and the fertilizers, irrigation, light and pest control are all used by high-tech means to harvest double the crops of the same size or sell them for a higher price......"

The movie screen changed directly, and I saw the grain and vegetables planted in the glass shed, sown and harvested by machines without human hands, as well as pipes that sprayed water automatically, and small airplanes that spread strange powders......

"That's what I know," Leo said, "and newer techniques, including more mature soilless cultivation, will be studied slowly in the future." ”

"Soilless cultivation?" I became interested in the term, "How can you grow without soil?" ”

"Essentially, what plants need is nothing more than sunlight, water, air and nutrients, and the soil just happens to provide water and nutrients, and it immobilizes the plants, and if we use other means, we can save space dramatically, and dissolve the nutrients directly in the water, and also improve the absorption efficiency, eliminate microbial infections in the soil, in a word, soil is not a necessity," Leo said. ”

As he spoke, he conjured up a "flower pot" made of a glass sink and an iron shelf, which was filled with many small plants, and because these pots were almost all transparent and had a strong ability to let in light, they were piled up in three or four layers.

In this way, the area of a house is planted with three or four layers of crops, which is equivalent to one piece of land becoming four ......

I'm running out of words.

Humanity's use of tools, their deep understanding of science, is indeed too far ahead of its time, and even some obvious shortcomings cannot obscure the fact that they have indeed solved the problem of food and survival.

"Hasn't the first day passed?" I asked.

"It's been sixteen hours now, and I don't mind if you're going to rest." Let's talk about the watch on your wrist.

"How can you be tired?" I said, "Go ahead!" ”

"Let's go, it's not fun just to watch movies, you have to go on a field trip!" Leo stood up.

The ensuing visit also gave me a lot of gains, but the novelty, shock, and even shock had slowly subsided, and in the end, I was even a little numb......

Strangely, it was about twenty hours later - I felt this way in my heart.

When I think about it, in the early days seven years ago, I stubbornly thought that Leo was a devil, but now it seems that he is not a devil, not an evil and cruel person, but he is definitely not a good person with good integrity.

Of course, there are almost no such people.

Except for the person in my heart......

Then again, a single earthling may not be able to do much damage to our world, and may even bring about some good changes, such as the invention that Leo is researching and improving.

However, if the Earth civilization and our planet's main plane meet and war breaks out, we will have no power to resist unless the gods come forward.

Even, according to Leo, even the gods may be a little unbearable......

Regardless of how credible this statement is, as long as there is a little possibility, it is enough to show that the human beings on the earth are far more terrifying than the demons in the abyss of hell......

For the next four hours, I suddenly felt a little tired.

In the soul space, the body is not tired, and I do not feel the taste and pain, so I know that this "tiredness" is because I have accepted too many new things, and my spirit and soul are close to overdraft.

So, I chose to use the last three hours to take a break and clear my mind.

We went back to the university and sat down at the door of the cafeteria, Leo conjured up the food, sat on the stone leaning on the side of the road, and said, "You think slowly, I also taste the taste of the following Coke burger......

The brown sparkling drink and golden bread and meat in his hand did not have any taste, but he made a look of enjoying and nostalgic, and ate it quite ritually.

I simply lay down on the lawn next to me, watched the sunset that was about to set but stopped in the sky, and said, "It's been an hour outside, isn't it?" ”

Leo said, "Almost, five days left...... When the sun rises again, I will go to class when the meeting is held......"

Before he could finish speaking, the sun sank, and the moon climbed rapidly to the middle of the heavens.

In fact, this is the second sunset in twenty-four hours.

I closed my eyes and imagined what it would be like to apply the new things I saw today to our planet, and my eyes narrowed slightly.

Leo suddenly said, "It's time! The first lesson of the school year, there are three minutes left, let's go, go to the classroom! ”
