Xia Hongsheng flickered Li Tai and diverted Li Tai's attention from the telescope, but Li Tai became keen to get Xia Hongsheng to quickly make a ship out of steel. It is said that he is ready to defeat Xia Hongsheng here, so he began to look for the best Bailian steel everywhere, because that thing is strong and heavy, in his opinion, even if Xia Hongsheng can make the embroidery needle float on the water, there is no way to make such a heavy boat made of Bailian steel still float on the water and not sink to the bottom.

It has been two days since Cheng Yanjin snatched the telescope from Xia Hongsheng's hands, and Xia Hongsheng pondered that if they really handed over the things to Li Lao Er, then Li Lao Er should also send someone to call him.

Sure enough, when it was close to evening, there were really guards in the palace who arrived at Xia Hongsheng's house in Chang'an and summoned Xia Hongsheng.

Xia Hongsheng had been prepared for a long time, but he didn't let the guard wait long, every time he came to summon Xia Hongsheng, and the two were acquaintances. Chatting and walking along the way, we soon arrived at the palace.

Without going through the report of the chamberlain, the guards directly took Xia Hongsheng to the main hall of the East Palace, and in the study, Li Shimin was waiting for Xia Hongsheng to come over.

"Xia Qing hasn't eaten yet, has he?" After Xia Hongsheng met Li Shimin, Li Shimin sat Xia Hongsheng down and said, "I want to have a few drinks with Xia Qing today and have a good chat!" ”

Saying that, he asked the waiter to pass the dishes and banquets, the two sat down at the table, Wang De poured a full glass of wine next to him, Li Shimin picked up a glass of wine, and said: "Xia Qing has solved many problems for me and the Tang Dynasty since last year, such as the method of making salt, and now my people in the Tang Dynasty can also eat good salt, and there is no shortage of salt in the army to cause soldiers to get sick. Then the horseshoe and saber are now ready one after another, and the officers and men in the army are all praised. As for the later methods of military training, the art of forging the body, the beheading of Tan Dian by special forces, and the deterrence of Feng An, there were 800 soldiers learning to read and write. Please be a famous general of the dynasty to teach experience, I will connect everything, only then did I suddenly realize that these things of Xia Qing are actually orderly and can be followed, and they are related step by step. Hehe. The education of 300 officers and men, I am looking forward to it more and more. Xia Qing's work is not much more than many ministers, come, drink this lamp! ”

Let's talk about it. He took the lead in raising his head and drank the wine in the cup in one gulp. Xia Hongsheng also raised his glass and drank the wine in the cup.

Damn, it's three pulp! Xia Hongsheng secretly complained in his heart.

"Xia Qing tastes this dish, although Xia Qing's cooking skills are unparalleled, but this thing, at this time, only I have here, haha!" Li Lao Er picked up the chopsticks and took a bite of the dish and ate it, and then said to Xia Hongsheng.

Xia Hongsheng scolded in his heart, isn't it a cucumber, next year when the greenhouse on my Zhuangzi will be put into use. How much and how much to have.

"Thank you, Your Majesty!" Although he thought so in his heart, he couldn't show it on his face, Xia Hongsheng looked grateful and picked up a mouthful of cucumbers.

"The day before yesterday, Duan Qing, Cheng Qing and others came to see me and gave me something, saying that it was a fairy treasure...... Hehe. Li Shimin looked back, and Wang De, who was standing beside him, immediately went over and took the telescope on the table with a very good eye, and put his hands in front of Li Shimin. Li Shimin took the telescope and said, "I tried it and stood on top of the gatehouse." Even the guards under the Suzaku Gate could see it clearly. Changed to human eyes, but they can't see there categorically. Xia Qing, these things are useless, but. I am also really curious, could it be that there are really immortals in this world, otherwise how could there be such a device that can make people see things hundreds of steps away? Therefore, Xia Qing is specially summoned to come to talk about it today. ”

As soon as Xia Hongsheng heard Li Shimin's words, he was a little disappointed. As a king of great talent. The first question Li Shimin asked was not about the education of military officers, nor about the practical use of telescopes, but it was such an illusory question -- after experiencing the role of telescopes, they immediately thought of the opportunity to explore the enemy!

However, perhaps since ancient times, kings have wanted to live forever, Qin Shi Huang is, Emperor Wu of the Han Dynasty is, and so does Tang Taizong. In history, Li Shimin was obsessed with swallowing pills in his later years, which led to long-term chronic heavy metal poisoning, and Li Shimin's death had a great relationship with this.

Xia Hongsheng suddenly began to regret that he had made up an excuse for a white-haired old man in Laojun Mountain in order to explain the origin of that knowledge.

"Your Majesty, if there are any immortals in this world, I'm afraid no one knows better than Weichen." Xia Hongsheng thought for a moment, and then slowly spoke.

It can be clearly seen that hearing Xia Hongsheng's words, Li Shimin's eyes suddenly lit up, and he immediately revealed a kind of anticipation and excitement.

But he heard Xia Hongsheng say again: "Therefore, Weichen can tell Your Majesty with great certainty that there are no immortals in this world at all, let alone any immortality." Human life, old age, sickness and death are like the unchanging law of a seed that sprouts in spring, grows in summer, harvests in autumn, and withers in winter. The so-called immortals are actually a group of people who are more intelligent and have mastered some knowledge and techniques that others will not know. The so-called immortality is not literal immortality. **It is destined to be born, old, sick and die, and then corrupted, returned to nature, and nourished all things. The real immortality is the spirit, what a person has done in this life, the cause and effect left behind, will affect others, a person has done things that can benefit countless people, then everyone will remember him, will learn from him, his spirit will be passed on, that is eternal life. ”

After speaking, Xia Hongsheng looked at Li Shimin quietly, the disappointment in Li Shimin's eyes was overflowing, and the light in his eyes dimmed little by little.

"Your Majesty, take this telescope as an example, it can make people see things in the distance, others don't know what the truth is, so they naturally think it's a fairy artifact, people who don't know the truth, plus some of their own imagination, they think that Weichen is a god, maybe they will give Weichen a nickname? For example, clairvoyance? Xia Hongsheng continued to say to Li Shimin: "But Your Majesty, you know that Weichen is just such an ordinary person. This telescope, if you take it apart and look at it, it's just two concave lenses, and there is a prism in the middle. Knowing the principle, anyone can make something. It's like taking water from the soil, people who don't understand it think it's a miracle, but those who understand that truth know that it's nothing more than a small skill of carving insects. ”

"Xia Qing, are you saying that those immortals and the like are really nonsense, and there is no possibility?" Li Shimin still had a glimmer of hope and asked.

Xia Hongsheng nodded and said, "Your Majesty, you are a wise monarch, you should also know that throughout the ages, among those Taoist priests who pursued immortality, which one of them really lived to the present?" On the contrary, Laozi is immortal, Confucius is also immortal, Mencius, Xunzi, Han Feizi...... They are all immortal, why do you say that, because their ideas are still influencing countless people, and their teachings are still remembered by countless people until now, so people still remember them and still learn from them. It is conceivable that people in the future will also remember them, their words and deeds, their doctrines, and what they left behind in the world. As long as there are people who remember them, they are immortal! So, Your Majesty, instead of exploring those ethereal things that do not exist, if you put your energy into this Tang Dynasty in your hands, let him become strong and rich in your hands, and make your subjects self-confident and proud, you will create a Tang Dynasty that will come to all countries, and you will create a glorious era through the ages, so that your glory will always be spread in this world, and your legend will always be talked about, so that you will live forever! ”

Li Shimin didn't speak, and Xia Hongsheng didn't speak anymore, just looked at Li Shimin quietly.

In the end, it is a generation of Ming Jun, Li Shimin's face faded rapidly, his eyes regained his light, his waist gradually straightened up, and his body suddenly emitted a vigorous and monstrous fighting spirit, and a smile suddenly appeared on his face: "Yes, I want to establish a rich and powerful Tang Dynasty, I want all countries to come to the dynasty, I want this Tang Dynasty to be eternal and prosperous, this is what I, the emperor of the Tang Dynasty should care about." Those ethereal legends only add to the troubles! ”

"Your Majesty Shengming!" Xia Hongsheng got up and bowed down and said: "Weichen is willing to do his best to help Your Majesty, help the Tang Dynasty, and eternal prosperity!" ”

"Xia Qing, sit down, I'm confused." Li Shimin waved his hand and asked Xia Hongsheng to sit down again.

After Xia Hongsheng sat down, he thought about it, and said to Li Shimin with a smile: "Your Majesty, although people cannot live forever, if the method is appropriate, it is not impossible to extend life. You are now in the prime of life, and if you take care of it as soon as possible, you will be able to live a long life. ”

"Oh? But how? Li Shimin asked.

"First of all, it is natural to ask famous doctors to have regular physical examinations to detect hidden dangers as early as possible and eliminate the symptoms of patients. Secondly, you need to pay more attention to your daily diet and mix your meals reasonably. Thirdly, exercise regularly every day to improve physical fitness and the body's resistance to patients. In this way, perseverance can prolong life. Xia Hongsheng said to Li Shimin.

Li Shimin nodded and muttered, "Listening to it, it seems to be similar to what the imperial doctor said." ”

"Yes, Your Majesty. In daily life, there are many things that are harmful to the body, and most of these things seem to have no performance or discomfort on weekdays, but they are secretly destroying the body bit by bit. Being able to get rid of these minor ailments will naturally prolong people's lifespan. Xia Hongsheng nodded and said, "Your Majesty might as well start with this physical examination, ask a famous doctor to do a thorough examination of all aspects of Your Majesty's body, and then formulate a set of daily meal plans according to Your Majesty's physique, and change them in stages according to the different parts of Your Majesty's body." Of course, His Majesty can also let the civil and military officials, harem ladies, and His Majesty's children experience it together, if they are ill, it is better to detect and treat them as soon as possible, and they can also show the emperor's grace. As for daily exercise, if Your Majesty can trust Wechen, Wechen can arrange your exercise plan. (To be continued.) )
