"It's already amazing. Yu Xiaoxiang looked quite impressed, "My country has a population of only more than one billion, but even foreigners say that such a little land can feed so many people, which is already a great achievement." What's more, the entire empire has a population of more than 50 trillion people. ”

"It mostly comes down to technology and land. Xiao Yichen nodded and said: "In fact, although the empire has a population of 57 billion, if you use food catalytic technology, even if the population increases tenfold and the arable area is reduced by ninety, it can still feed the people." ”

"Hey? Then why does Northern Qi keep asking us to buy grain or something? I heard that there are often famines. Yu Xiaoxiang asked puzzled.

"Hehe, this has something to do with the health of the people and longevity. Xiao Yichen said with a smile: "In fact, this catalytic technology has been perfected tens of thousands of years ago. However, with the development of modern biotechnology, the ultimate lifespan of species has been discovered, for example, it is often said that the average lifespan of people on the ground is 500 yuan, which is the limit lifespan. However, to achieve this ultimate lifespan, many conditions are required, not only changes in medical technology, but more importantly, nutritional intake. Although it is also possible to simulate imitation nutrients, firstly, because the cost is more expensive, and secondly, due to technical limitations, many things cannot be completely simulated and manufactured, so naturally produced food has become one of them. If the catalyzed food is used and eaten for a long time, the limit life of the species will be reduced, which is equivalent to the loss of life. Therefore, as long as life is still passable, even civilians will not buy catalytic food. And then there's the cultivated land. For example, in the case of the empire itself, there are more than four million habitable stars, almost ten times as many mineral and captive planets, and many of these planets can be directly used for farming, so there is no need to vigorously develop in promoting food. And the living standard of Northern Qi is higher than that of Long Han, how could civilians be willing to eat catalytic products. ”

"I see. Yu Xiaoxiang nodded and said in understanding: "If you live a good life, you want to live a long life." Also, if it were changed to the earth, it is estimated that no matter how expensive it is, some people will be willing to eat it. ”

"People's desires are like this, to live well, to eat well, to dress well, to live a long life, to have children and grandchildren, and so on. Ordinary people, how many people want to be emperors and generals?" Xiao Yichen said with a smile.

I didn't know what to think, Yu Xiaoxiang suddenly poked her head over, stared at Xiao Yichen and asked, "Speaking of which, last time I saw that kind of treatment and repair cabin in the Imperial Medicine Department of our Lingxiao Palace, that thing can really cure people's illnesses instantly?"

"It's an exaggeration to say that it was instantaneous, but so far, as long as it is not an instant death, the current medical cabin can be 100% cured. Xiao Yichen nodded and said with a smile: "Now you can still see that those who are disabled are generally born like this, or because they have been delayed for too long, their limbs have completely died." Since the countries of the stars have uniformly banned biological replication technology, if a hand is broken for too long, then there is no way to make a new copy hand for him. But in fact, it doesn't matter, as long as the average person spends a little money, they can install a realistic arm, which is not much different from a normal hand. ”

"Wow, that's amazing. If you let our people know about it, you won't be so happy that you can't close your mouth!Hey, big villain, how did you do it?" Yu Xiaoxiang, the curious baby, began to dig into the bottom of it again.

"It's very simple, it's really just to solve the problem at the source. If it is caused by a virus, it can directly kill the virus in the body. In the case of a disease, the diseased cells are removed and new cells are replaced. It does not mean that it will not recur, but it can be immunized for a long time. After that, just do it again. At the end of the day, it is to let the species essentially use healthy cells and tissues all the time, and naturally no disease can appear. Xiao Yichen's answer this time was simple and easy to understand.

"So, don't you keep using new cells to live forever?, so what's the limit of longevity?" Yu Xiaoxiang asked again with a frown.

"This is determined by the species itself with the markers. When the limit of lifespan is reached, the cells will degenerate across the board, and no matter how much you try to grow new cells, the rate of deterioration will get faster and faster. If it is a body cell, you can also use regular cell repair to alleviate one or two, but ......" Xiao Yichen stretched out his hand and nodded at the cute head of the mantis, and said with a smile: "When your brain cells begin to degenerate and decay in large quantities, the new cells that are re-cultivated will not record your memory." In other words, slowly, even if your body is still alive and you have lost all your memories and experiences, can you still call yourself you? In fact, it is already another person, so no one likes to use this method of extending life, and naturally it is also eliminated. Besides, even if cell repair technology is no longer an aristocratic technology, it still requires a certain amount of money, and most people can't afford to pay for it every day. ”

"Well, there are good and bad. But it's not bad, if you can live for five or six hundred years, you will become an old monster. Hee-hee. Yu Xiaoxiang giggled, and her sweet and lovely appearance also made Xiao Yichen's eyes shine.

Reaching out and grabbing the little hand on his shoulder, Xiao Yichen motioned to the little beauty behind him to stop, then propped up his body and said, "Let's go, let's go to the imperial grandmother." ”

"Okay, wait a minute, I'll go get your big gun, it's cold outside. Yu Xiaoxiang jumped up, beat her little short legs that were a little numb twice, and then rushed to get something, which made the smile in Xiao Yichen's eyes a little stronger.

……

"Good grandson, quick, come to the imperial grandmother here. ”

As soon as she entered the Warm Smoke Pavilion of Ci'an Palace, where the Queen Mother was located, she saw that she was already waving to Xiao Yichen with a smile on her face, and she didn't seem to want to wait for her to salute at all.

"The grandson knocks on the imperial grandmother. Xiao Yichen still bowed, then took off the big hat and handed it to Yu Xiaoxiang behind him, walked to the side of the queen mother on the throne, and said while sitting down: "Grandma Huang, the weather has been getting colder and colder recently, are you okay?"

"Okay, I don't move anywhere, what's wrong?" Reaching out to hold Xiao Yichen's palm, the Queen Mother glanced up and down a few times, and raised her hand to touch the handsome face with some distress, "The good grandson has lost weight recently, and his complexion is not as good as before, but what is the relationship with the star poison?"

"It's not that the weather is bad, the amount of food is also small, and there have been a lot of things recently, so the complexion is worse, so don't worry about the royal grandmother. Xiao Yichen said indifferently.
