On the banks of the Qinhuai River, the morning is full of fog.

A gust of wind blew, rolling up the willow leaves on the shore, and the branches swayed in the sky, light and agile.

In a teahouse on the bank of the Qinhuai River, Zhu Di, dressed in casual clothes, and Dao Yan, dressed as an old monk, were eating breakfast.

Zhu Di took a crystal clear xiaolongbao, and when he bit it, some salty juice splashed in his mouth.

"It's been a long time since I've had such a comfortable breakfast."

Dao Yan said with a smile: "Your Majesty has preliminarily solved the problem of removing the guards of the feudal domains and supporting the clan, and has set the tone of maritime trade, so naturally you can breathe a sigh of relief. ”

"Didn't the master say that day, don't you come with me to listen to Jiang Xinghuo's lecture?"

Zhu Di's words were a little ridiculous, obviously he was in an excellent mood today.

Dao Yan didn't care, turned the rosary and said: "Lao Gu originally felt that this person was not controlled, and it would have an impact on the dispute between the princes, so he persuaded His Majesty to kill him." After experiencing things such as chessboard rice and cutting feudal systems, I am indeed a little curious about this person. ”

"But in the final analysis, it was last night that I watched the sky at night, and if I realized something, I decided to go to the edict with His Majesty today."

Zhu Di took a sip of porridge and asked again: "How does the master think Jiang Xinghuo's intelligence and knowledge compare to you?" ”

"Since Liu Bowen's death, no one in the world can compare with Lao Wei." Dao Yan replied indifferently.

Dao Yan's answer was natural and confident.

In fact, although Dao Yan had suspected that Jiang Xinghuo might be an immortal.

But Dao Yan just said that, which doesn't mean that he really believes it.

If it weren't for the fact that he had realized the phenomena at night, Dao Yan would not have decided to listen to Jiang Xinghuo's lecture in person.

And this time he came to listen to it in person, if what Jiang Xinghuo said this time was not so amazing, then Dao Yan could conclude that the so-called immortal theory was just that he was overthinking.

Zhu Di was dumbfounded for a while, and pointed at the old monk opposite with chopsticks.

"Master, you're still the same...... When I was still the king of Yan, before I became a vassal, the master recommended himself, saying that his wisdom is unparalleled in the world, I didn't believe it that day, and now after 20 years of wind, frost, rain and snow, I found that what the master said was true. ”

Dao Yan smiled slightly, obviously extremely confident in his resourcefulness.

Dao Yan said slowly: "The two questions raised by Jiang Xinghuo, Lao Qu already has his own answers, and Lao Qu has some kind of doubts about Jiang Xinghuo's things that cannot be said for the time being. ”

"Master suspicion?"

Dao Yan shook his head, and Zhu Di didn't ask.

In fact, Dao Yan suspects that Jiang Xinghuo's lecture is called "The Theory of National Fortune", but it may be another legendary science.

- Dragon Slayer!

But this kind of doubt, just like the saying of the immortals, could not be confirmed, so Dao Yan did not say it to Zhu Di.

Zhu Di nodded and got up, pacing faster and faster in the teahouse cubicle, and his brows became tighter and tighter.

Before, Zhu Di's mind was all on matters such as the peaceful reduction of the domain, the reform of the system, and maritime trade, and he did not think too seriously about the questions raised by Jiang Xinghuo, but waited for Dao Yan to think about it and then copy the reference answer.

And now that he thinks about it himself, he has found some clues.

Zhu Di secretly thought: "I am confident that if I can have twenty years, I will definitely be able to sweep away the Northern Yuan Dynasty and return the Ming Dynasty to a prosperous era, just like Emperor Wu of the Han Dynasty and Taizong of the Tang Dynasty...... But according to what Jiang Xinghuo said, the future of my future son will be inferior to the next generation, and in the end, the authority will be stolen, and then the country will die? ”

Zhu Di stopped, he shook off his cloth robe, and looked at Dao Yan.

"Master, you read the history books well, can you tell me how many years the Han dynasty has existed from the Han Dynasty to the present?"

Dao Yan had already found out the accurate answer in the past two days, and he said unhurriedly.

"209 years in the Western Han Dynasty, 195 years in the Eastern Han Dynasty, 51 years in the Western Jin Dynasty, 103 years in the Eastern Jin Dynasty, 37 years in the Sui Dynasty, 289 years in the Tang Dynasty, 167 years in the Northern Song Dynasty, and 152 years in the Southern Song Dynasty."

After listening to this number, Zhu Di suddenly felt a sense of crisis.

Zhu Di looked at the painted boat with lanterns still lit on the Qinhuai River, and simply made a calculation.

His father Zhu Yuanzhang has been the emperor for 31 years, and his eldest nephew Zhu Yunwen has been the emperor for 4 years, and he Zhu Di is forty-two years old this year, and he can be the emperor for 20 to 30 years according to the degree of physical toughness, but if the average life span of the dynasty is 150 to 200 years, when he is passed to the next generation, the Ming Dynasty has already passed nearly one-third of its lifespan!

How to prolong the life of the Ming Dynasty?

Since the unification of the Qin Dynasty, what is the red line of time that does not exceed 300 years?

"Amitabha." Dao Yan saw Zhu Di's thoughtful appearance, and indifferently moved the prayer beads, "Your Majesty is upset, why don't you take a rest here, you and I can get the answer by going to the edict together at noon, why bother to hurt your mind in vain?" ”

Zhu Di paused, but laughed at himself.

"What the master said is very true, if you are born in the peaceful world, be a rich and noble prince...... It is also excellent to have breakfast with a close friend like the master on the bank of the Qinhuai River and drink tea leisurely until noon. ”

"If Your Majesty is a rich prince who only knows how to travel to Qinhuai at night, the old man will not have to go to others long ago."

Zhu Di and Dao Yan worked together to do the rebellious monarchs and ministers, and they couldn't help but smile at each other.

............

Edict, Secret Room.

Zhu Di, who had taken a good rest, sat on the chair with Dao Yan in high spirits, ready to eavesdrop on Jiang Xinghuo's lecture today.

Fortunately, Jiang Xinghuo didn't sell anything today.

And Dao Yan, who came to listen to it for the first time, noticed that Zhu Gaoxu's temperament next door did sound different from before.

Zhu Gaoxu said politely: "Mr. Jiang, I didn't understand any of the two questions you asked last time. ”

It's you!

Jiang Xinghuo was basically familiar with the intelligence level of this reckless student.

Therefore, Jiang Xinghuo is not angry.

And he didn't take the baby to help with homework, he just took money to give lectures, and he couldn't get angry.

"It's okay, just talk about it slowly today."

Zhu Gaoxu asked embarrassedly: "Then can Mr. Jiang tell me the answers to the questions raised before?" ”

"It can be answered that this is the beginning of "The Theory of National Fortunes." Jiang Xinghuo leaned on the trunk of the tree and bowed slightly, "Of course, there is a lot of content in "The Theory of National Fortune", and it will definitely not be finished in just one day, so it will be talked about in stages." ”

"Our first lesson is the concept and essence of dynasties, the evolution of the three forms of dynasties of slavery, feudalism, and unification."

Jiang Xinghuo gave an affirmative answer, but said: "Answering these questions can't avoid another question at the same time." ”

"What's the problem?" Zhu Gaoxu asked with interest.

"Since we are going to explore the fortune of the country, that is, the life of the dynasty, by talking about the "Theory of the Fortune of the Country", have you ever wondered, what is a dynasty?"
