Lu Dongzan was named the general of the right guard by Li Shimin, and enjoyed the loose official Lu of the three products.

He was not worried about Li Shimin's divisive plan, because Songtsen Gampo was a British lord, and he trusted Lu Dongzan. Lu Dongzan had already sent someone to tell Songtsen Gampo about this.

During Lu Dongzan's time in Chang'an, in addition to being shocked by the prosperity of Chang'an and the strength of the Tang Dynasty, he was also very interested in the two people.

One is Li You, the king of Qi, who has heard a lot of stories about this prince and wants to get to know this prince. However, it is said that this person has been in a mining school in a foreign country, and he has not had the opportunity to meet him for the time being.

The other is Li Chunfeng, who is even more interested in this real person.

Lu Dongzan is very knowledgeable, or very miscellaneous, he is not religious, only believes in himself. But he knew a lot about Tibetan Buddhism and Taoism, because he found that both could be used.

Recently, he suddenly felt a little confused, because Li Chunfeng's performance was really inexplicable to him.

Especially recently, the legend of Tui Beitu aroused great interest in Lu Dongzan, who supported Songtsan Gampo and was committed to the revitalization of Tibet, and wanted to calculate the national fortune of Tibet.

Not long ago, he heard the news that the Tang Dynasty sent troops to Tuyuhun, and he was even more worried about Tuyuhun's fate.

So, he came to visit Li Chunfeng.

Hearing that Lu Dongzan was visiting, Li Chunfeng personally greeted him at the gate.

Li Chunfeng is a fourth-grade official, and Lu Dongzan is a member of the third grade, he wants to salute Lu Dongzan first, and he said: "I have seen the general in my humble position." ”

Lu Dongzan returned the salute and said: "Li Zhenren is polite, I am here today as a Taoist friend, let's not do the same thing in the officialdom." ”

"That's the best." Li Chunfeng said with a smile.

Li Chunfeng accompanied Lu Dongzan to the guest room.

"Sir." A servant came over and reported: "Madame is in the guest room, there are too many guests these days, Madame asked her to clean up the guest room." ”

Li Chunfeng hesitated for a moment and said, "General, please come to my study." ”

Entering the study, Li Chunfeng took a quick step, put away some things on the desk, and put them in the drawer.

Lu Dongzan sent his own gift, which was the Xu Yuan ginseng of Tubo.

Li Chunfeng once heard Li You say that Xu Yuan ginseng is born in dense mountain forests hundreds of meters above sea level, grows in extremely cold areas, blooms in 3 years, bears fruit in 6 years, and is very useful for stewing meat and wine.

Li Chunfeng was very happy, he didn't know what gift to give Li You, and now he borrowed flowers to offer Buddha, which can be regarded as something related to eating.

Taking advantage of the maid's efforts to make tea for them, Lu Dongzan looked at Li Chunfeng's study.

On the front wall of the study, a common Taoist picture of Qiankun gossip is drawn. On the side wall is a sketch with a lot of slogans, and some arrows and lines are drawn in the middle, as if something is unfinished.

After the maid left, Li Chunfeng picked up the teacup and motioned for Lu Dongzan to drink tea.

Lu Dongzan took a sip of tea and said, "Li Zhenren, I heard that you are very good at arithmetic, and I also like it." ”

"Oh? Really, that's great. Li Chunfeng was obsessed with arithmetic and immediately became happy.

Lu Dongzan was very smart, and his wit left a deep impression on the people of the entire Chang'an.

Li Chunfeng really wanted to compete with Lu Dongzan, so he stood up, brought a pen and paper, and moved out the variant of the chicken and rabbit in the same cage.

"A squirrel collects pine nuts for the winter, and it can collect 20 on sunny days and 12 on rainy days. It collected a total of 112 pieces for 8 consecutive days, may I ask, how many days are sunny and how many days are rainy? ”

Lu Dongzan was fascinated at once, and immediately immersed himself in the topic.

Seeing Lu Dongzan's focused expression, Li Chunfeng couldn't be happier, he said in his heart: "You can't count your toes." ”

Lu Dongzan calculated carefully, and counted the time of two incense sticks, but he really couldn't calculate it. He wiped the sweat from his head and said sincerely: "Li Zhenren, I am stupid, I really can't figure it out." ”

Li Chunfeng laughed and told Lu Dongzan the result very proudly.

Seeing Li Chunfeng's smug demeanor, Lu Dongzan was also secretly proud in his heart. He had studied Li Chunfeng and knew that he had the best bite. Don't say that Lu Dongzan can't figure it out, even if he does, he will pretend that he can't figure it out.

Sure enough, after this round, the more the two talked about speculation.

Lu Dongzan was interested in things about the national fortunes of Tubo, and he curryed favor with Li Chunfeng for this purpose.

He said: "Li Zhenren, you are the person I admire the most." A while ago, I heard that His Majesty the Emperor summoned you to inquire about the fortunes of the Tang Dynasty. I'm really worried about you. ”

As soon as he said this, Li Chunfeng suddenly became alert, and he said: "My Tang Dynasty has a long fortune, Your Majesty is wise and martial, generous and open-minded, what is there to worry about?" ”

Lu Dongzan said with a smile: "Li Zhenren didn't tell the truth, people are born, old, sick and die, and countries also rise and fall, how can there be a country for more than a thousand years in ancient times?" ”

Li Chunfeng said dejectedly: "You're right, I almost won't be able to come back." ”

Lu Dongzan said: "You can sit here now, and you have been rewarded by Your Majesty the Emperor, I admire your wit, and I want to know how you resolved the crisis?" ”

Li Chunfeng said: "This matter has been held in my heart for a long time, I can't tell anyone, but it doesn't hurt to tell you, you are an outsider, even if you go out to tell others, no one will believe you." ”

A person has a big secret in his heart, which is very uncomfortable, and he needs to find an irrelevant person or place to vent it.

Lu Dongzan said: "You trust me so much, I will naturally keep it a secret." ”

Li Chunfeng stood up, took out a piece of drawing paper from the drawer, and showed it to Lu Dongzan.

Lu Dongzan saw that the painting had a plate painted on it, which contained 21 plums.

I saw that it read:

The proverb said: "Fruitful fruits, innumerable; One fruit and one kernel, that is, the new is the old. The song said: "All things are born in the soil, and the twenty-nine come to fruition first." Unification of the Central Plains, Yin and Yang are exhausted first. ”

Li Chunfeng said: "This is my Datang's national fortune.

A plate of fruit is Li Shiye, whose number is twenty-one, and it is twenty-one from the beginning of the high ancestor. Twenty-nine refers to the year 289 of Tang Zuo. ”

It means that this plate of fruit is plums. The so-called plums naturally refer to the old Li family of the Tang Dynasty. And how many plums are there? There are 21 plums on a plate, which is an allusion to the fact that there were 21 emperors in the Tang Dynasty.

Li Chunfeng used the I Ching to explain the basis of his reasoning to Lu Dongzan in detail.

Lu Dongzan was deeply impressed by Li Chunfeng.

He asked, "How did you tell His Majesty the Emperor?" ”
