"No, you don't think about it, throw it at me, do you think it's appropriate? You're the emperor, don't all the emperors want to live forever? Li Chengqian asked Li Shimin speechlessly.

"It's suitable, why isn't it suitable, as for immortality, even such a powerful Yuan Tiangang is hanging, plus the countless experiments of the Academy of Sciences, who still believes in immortality, it's either sick or idiot" Li Shimin said to Li Chengqian angrily.

Li Chengqian saw that his father replied very seriously, which made Li Chengqian have a trace of emotion, his father has really changed, and he is not as obsessed with immortality as in history, of course, this may also be because his wife has had regular examinations and treatments by Sun Simiao in recent years, and his body is not as good as in history, but what makes him even more puzzled is that what has this academy done for more than a year has actually made his father so respectful.

At the same time, Li Chengqian is also secretly blaming himself, he has been too loose for more than a year.

"Don't be stunned, tell me what your back hand is, since you can bring it up, then you should have already thought of a countermeasure" Seeing Li Chengqian standing there stunned, Li Shimin urged with some impatience.

"Daddy, are you so sure that I must have left my hands behind?" Hearing his father's urging, Li Chengqian asked a little depressed.

Why is he depressed, it is because his father is right, he has thought about this problem for a long time, or he has seen the future development, he is depressed because his father is so sure that he has a backhand.

"I don't know you yet, you always presuppose the worst case first, and you will do it only after determining that the worst possibility of the preset is within your tolerance, and many things, you do it premeditated, just like that, do you think I will believe that you have no back?" After Li Shimin finished speaking, he asked Li Chengqian rhetorically.

"Alright! Dad, even if you are powerful, I have indeed thought about that question, but when answering your question, I would like to ask you a question first, what kind of relationship do you think business, the military, education, and industrial science and technology, that is, the Academy of Sciences and many workshops, what kind of relationship do they have?" Li Chengqian looked at his father after speaking, he wanted to know how his father would answer.

"These, does it matter? It doesn't matter! When Li Shimin heard Li Chengqian's words, he thought about it for a long time and didn't come up with anything to do with it.

"Does it really matter? For example, if there is no mass production in the workshop, and there is no reselling by merchants, it is a useless thing, but if it goes through this chain of production and resale, it will eventually flow into the hands of ordinary people, and if the people want to buy it, they have to pay, and where does the money come from, either to work in the workshop, or to help the merchants to work, or to grow food for money, but no matter what, these people are creating value, this is a cycle, so they don't have a relationship? Li Chengqian simply gave an example to explain to Li Shimin.

"Gao Ming, this is not right, how can this be a cycle, businessmen earn people's money, and workshops earn businessmen's money, and the people are making money with labor, this is a cycle, I know, but what is the matter with the Academy of Sciences" Li Shimin heard Li Chengqian's narration, and asked Li Chengqian with some doubts, after all, what Li Chengqian said has been like this since ancient times, there is nothing to say, he also knows, but the Academy of Sciences, he is a little confused.

"Dad, have you forgotten one thing, that is, the imperial court, and the patent department" Seeing that his father hadn't turned the corner yet, Li Chengqian asked his father with a smile.

"You mean, yes, this workshop has to pay money to get the invention of the Academy of Sciences, plus the workshop, the merchants, have to pay taxes regularly, and even the people have to pay taxes, if so, it's really a cycle, and it's also a good cycle, as long as this cycle is developed well, then there will be more and more things created, is that what Gao Ming means?" Li Shimin is not stupid, Li Chengqian only dialed it a little, and he figured out the key.

"That's right, that's the case, but think about maintaining this cycle, the external environment, and the internal environment should be good, otherwise this cycle will get worse and worse, and finally disappear, and ........."

"What is the external environment and the internal environment, you tell me about this" Hearing Li Chengqian say a new term, Li Shimin couldn't wait to ask Li Chengqian.

"This external environment is very easy to understand, that is, there is no imperial invasion around Datang, and there is no war in Datang, only if the external environment does not change, that cycle can be stable, otherwise if Datang is often at war, then Dad, how many people do you think can produce stably, and to maintain the stability of the external environment, it involves the army and soldiers, only a strong army and loyal soldiers can maintain the stability of the external environment, so is it not the relationship between the army and commerce, workshops, etc." Li Chengqian explained to Li Shimin what the external environment was, and at the same time drew out the connection between the military and these.

Regarding what Li Chengqian said, Li Shimin nodded to Li Chengqian to show his understanding after thinking for a while, but he did not speak, and motioned for Li Chengqian to continue.

"After the external environment is finished, the internal environment is also very easy to understand, its core is education and stability, why education and stability, because only education can cultivate a large number of talents, let them engage in the research and invention of the Academy of Sciences, to engage in business fraud, to manage those ordinary people, without education then can not cultivate these talents, without these talents, then the cycle just mentioned can not develop, this is education, and stability, is the court and the authorities, Establish a healthy and sustainable stable environment for this cycle, including laws, policies, and law and order, and only when these are established, then the internal environment will be stable.

And for the development of the external environment and the internal environment, a lot of money is needed, so where the money comes from, it can only be taxes, and taxes come from the business cycle just mentioned.

So now Dad, do you still think that what I just said is okay? After Li Chengqian finished speaking, he looked at Li Shimin and asked with a happy smile.

"According to what you say, of course there is a connection, and the connection is still very large, this is basically a model that a country should have if it wants to be strong, but these are what you said before, there are more and more people who read, and the policy of fooling the people is not working, what is the connection" Li Shimin listened to Li Chengqian's account and agreed with his statement, but there were some problems, and he still couldn't figure it out.
