Li Ke originally wanted to stay in Chang'an for a longer time, and at least he had to wait until Concubine Yang was enthroned and the matter was settled before he could return to Taiyuan. However, after a detailed business with Xu Jingzong, he thought it would be better to go back to Taiyuan in advance. Li Tai and Li Chengqian wrote a letter to Concubine Yang was enthroned and the matter was very sensitive. Xu Jingzong believed that if he stayed in Chang'an, there would be a negative impact. Since he could not do much, why not avoid this quagmire and wait for the result? Maybe he could act according to the opportunity and add fuel to the fire!

Li Ke thought Xu Jingzong's analysis was very reasonable, so he discussed with Xu Jingzong and decided to leave for Taiyuan in two days.

The next day, Li Ke came to Li Jing's Duke's Mansion and told Li Jing about his return to Taiyuan. Li Jing had already agreed to Li Ke's going to Taiyuan, but he had already prepared. Seeing that Li Ke was going back to Taiyuan, he was ready to go with Li Ke. Li Ke left Li Jing's mansion and took Xu Jingzong to the palace to meet Li Shimin. He wanted to ask Li Shimin for another question before leaving and wanted his approval.

When the two arrived at Liangyi Hall, Li Shimin had just discussed with Fang Xuanling, Li Jing, Cen Wenben and others about the money and food issues of the Tang Dynasty when the war began in Tuyuhun. He was also very worried about the finances of the Tang Dynasty. When Li Ke saw Li Shimin, his face was not very good.

"You have something to do?" Li Shimin asked lightly.

"Father, I will be ready to leave Chang'an to Taiyuan tomorrow. I want to report to you about the Beifu Bank before leaving and ask for your opinions!" Li Ke said respectfully.

"Beifu Bank?" Li Shimin repeated, as if he had forgotten that Li Ke explained to him that he was a financial institution that he agreed with very much.

"Yes, I opened it after asking for your advice!" Li Ke reminded Li Shimin.

Li Shimin recalled for a moment, and then he realized that there was indeed such a thing, "What do you want to say to me?"

"When I went back to my father, I found that whether it was Chang'an or Taiyuan, merchants and people used copper coins to pay for trading and trading. However, when the transaction volume was large, copper coins were inconvenient to use and were not convenient to carry, causing a lot of trouble to the transaction!" Li Ke said carefully, "So, I wanted to invent a banknote instead of copper coins!"

"Oh—" Li Shimin was surprised, and he immediately became interested, "Use banknotes instead? Tell me about your specific operations?"

"My son has summoned Xu Jingzong from the Northern Prefecture Bank to the outside of the hall, and ask his father to announce him to come to the hall to tell you!" Li Ke suggested to Li Shimin.

"Xu Xu Jingzong!" Li Shimin said to Wang Dedao.

Wang De left Liangyi Hall and brought Xu Jingzong in in a moment!

It was the first time that Xu Jingzong met the saint, and he felt a little nervous. When he saw Li Shimin, he hurriedly bowed!

"My minister Xu Jingzong meets the emperor!"

"No need to be polite, get up. I heard that you are in charge of the Beifu Bank. What is the specific situation? Let me tell me!" Li Shimin asked Xu Jingzong.

Xu Jingzong stood up and bowed to Li Shimin, "Return to the emperor, Beifu Bank has been established for four years, mainly engaged in the storage and lending business of money. In the past four years, it has developed rapidly. There have been many branches in Bingzhou, and the depositors have reached more than 500,000, accounting for one-tenth of the entire Bingzhou household registration."

"Yeah—" Li Shimin nodded. In fact, he didn't understand these professional words of Xu Jingzong, but he could look at people and stayed in the top position for a long time. He could tell whether ordinary officials were lying to him. Xu Jingzong seemed very confident when talking to him, his tone was calm and he didn't have any panic. He knew that the young man in front of him was not talking to him.

"I heard from Li Ke that Beifu Bank wants to issue paper money instead of copper coins. How do you want to do it specifically!" Li Shimin asked.

He is a king who is good at listening to opinions. Therefore, he would not refuse to listen to the suggestions of Li Ke and Xu Jingzong before he was sure whether what Li Ke said was feasible.

"Your Majesty, please see, this is a banknote designed by the Northern Palace!" As Xu Jingzong spoke, he handed a wooden box to Wang De next to him.

Wang De opened the wooden box and put a few rectangular pieces of paper, but the sizes were different. The printed on the paper was very beautiful. Wang De handed these pieces of paper to Li Shimin. Li Shimin held them in his hand and looked closely. He saw that the rectangular paper had different sizes. The certificate on it was printed with Chang'an City, with Mount Tai printed on the back, and the four words Beifu Bank were written in ancient seal script, running script, cursive script and regular script in the middle. There were ten, twenty, fifty words on the left side of the paper.

Wenhe, one hundred words, one hundred guan, ten guan, twenty guan, fifty guan, one hundred guan and other words. Li Shimin knew that this was what Li Ke said to replace copper coins. He held one of them in his hand and touched it with his fingers a few times. He felt that the paper was very smooth and looked very good. The golden banknotes were shining with golden light under the sun, which was very beautiful. Li Shimin held the banknotes in his hand and carefully looked at them. The absolute first-class standards of paper and printing made him a little unwilling to let go.

"Well, this banknote is done well!" Li Shimin said with satisfaction, "But this banknote is too simple, there will be a lot of counterfeit coins among the people, right?"

"Father, the paper of this banknote is carefully made with special materials, and the printing is very crafty, so others cannot imitate it!" Li Ke said seriously, "As long as the Beifu Bank is issued, the paper production and printing technology are all controlled in Beifu, others cannot imitate such exquisite papernotes. As long as the counterfeit currency they imitate is released, the real and fake will be debated!"

"Then how do you plan to issue it? How can you make the people believe that he can replace copper coins?" Li Shimin asked.

"Your Majesty, you also know that ten or fifty stans are the pre-value of the banknotes. The Weichen's method is to link the banknotes to gold and determine the exchange standard for banknotes and gold. The people feel that the banknotes in their hands are not at ease, so they can go to the Beifu Bank to exchange for gold. On the contrary, if they feel that copper coins and gold are inconvenient to use, they can go to the Beifu Bank to exchange for banknotes." Xu Jingzong began to talk freely, "Also, once the Beifu government issues paper money, the salary of the Beifu officials and the military pay of soldiers will be replaced by banknotes, and the shops opened by the Beifu gentry will also accept the purchase of banknotes."

Li Shimin listened in detail. He thought Li Ke’s suggestion was very bold, but after listening to Xu Jingzong’s story, he felt that it was only desirable, especially linking paper money to gold, which greatly improved the value and credibility of paper money.

"How confident are you to issue it in Beifu?" Li Shimin asked Li Ke.

"About 80%!" Li Ke didn't dare to say too much.

"80%? It's enough to try it!" Li Shimin said lightly, "But you two know the consequences of the failure of this matter. Do you have the courage?"

"Yes!" Li Ke and Xu Jingzong said at the same time.

"Okay, then I agree to you issue banknotes in Beifu!" Li Shimin said after pondering for a moment.

"Thank you, Father!" Li Ke said happily. Then, he said to Li Shimin again, "I'll ask my father to name this banknote!"

He is giving Li Shimin a high hat and named the banknotes. This is definitely of great significance and is also a kind of flattery for Li Shimin.

"Blank, let's just use it Tang coins!" Li Shimin said for a moment.

"Thank you, Father!" Li Ke gave Li Shimin a gift. Li Shimin asked Xu Jingzong to leave Liangyi Hall, and then told Li Ke something about him taking good care of Li Zhi, which made Li Ke leave Liangyi Hall.

Li Ke left Liangyi Hall and came to Qianqiu Hall to tell Concubine Yang and Li Zhi that she had decided to leave Chang'an and meet Taiyuan. Concubine Yang saw that Li Ke had not lived long before she was in Chang'an, and she felt reluctant to leave, but she also heard that the Tang Dynasty was about to start a war with Tuyuhun, and the Northern Palace was going to send out 100,000 cavalry. Knowing that Li Ke had a lot of things to deal with when he returned to Taiyuan, he didn't say much. Instead, Li Zhi, who was standing by, heard that Li Ke was going to Taiyuan, was very happy. Because when Li Ke returned to Taiyuan, he could also go to Taiyuan with Li Ke. He had been waiting for Taiyuan and for following Li Ke for a long time!

Li Ke told Li Zhi the time of departure the next day and asked him to go to Beiwang Mansion to find him in the morning. Li Zhi nodded and agreed. Li Ke chatted with Yang Fei and Princess Qinghe Li Jing for a while, and then left Qianqiu Palace in the face of everyone's reluctance.
