Because the watermark of the special paper for banknotes is added in the process of papermaking, the paper in the warehouse is watermarked. In the currency, the largest number of uses is 1 piece, so the proportion of paper in it is naturally prepared according to the number of issuances, so the amount is sufficient.

Even if you put aside the 100 and 50 banknote paper that cannot be used, the remaining 1, 5, 10, and 20 pieces are enough.

"You can go out, it is estimated that the time to go out this time is not short, you have arranged your follow-up things, as for the court, what do you have to do here? Tell me? Li Shimin looked at Li Ke and said.

Li Ke glanced at Li Shimin with a confused expression, what are you asking me to do in the court? I will never respond.

"Dad, you just look at the whole thing, anyway, twenty-one, oh no, twenty-two has already been written for you." Li Ke said quickly.

Li Shimin glanced at him, "Okay, anyway, you can arrange everything you are responsible for." ”

"Yes! Then the minister went first. Li Ke said.

"Wait, there's one more thing." Li Shimin stopped Li Ke.

"What's the matter?" Li Ke was a little puzzled.

"Tubo Songtsen Gampo sent Lu Dongzan to Chang'an, and not long after he arrived, he sent a large number of gifts, and also mentioned yaks, sheep, etc., which were said to be transferred to the Tang Dynasty personnel in Xizhou." Li Shimin said.

"Anything else?" Li Ke asked.

"No, it's basically the same content, what do you think he wants to say?" Li Shimin looked at Li Ke and asked.

Li Ke's actions in Xizhou and Tubo Li Shimin all knew and understood, he didn't interfere, many things were not even put on the court, and the fewer people who knew some things, the better.

"I think Songtsen Gampo should have gotten some benefits." Li Ke thought for a while and said, after crossing the South Kunlun Mountains (later Himalayas), in fact, the temperature on the south side was very high even in winter, and the winter in Lhasa was actually not so cold.

In other words, with Songtsen Gampo's temperament, if he wanted to do it, he might have done it last winter.

After Li Ke negotiated the relevant trade with the Songtsam cadres last year, there was no problem in making 1,000 sets of Mingguang armor with the iron tools that Songtsam Gampo bought.

In other words, I am afraid that Tibet will not be at peace this winter.

"So there's a chance your strategy has succeeded?" Li Shimin looked at Li Ke and asked.

"Otherwise, their posture would not be so low, in this way, I will go to see Lu Dongzan." Li Ke thought for a while.

"Okay, you watch the processing." Li Shimin nodded, "I don't know anything here, just let Honglu Temple deal with it normally." ”

"Daddy is wise." Li Ke slapped a sycophant.

"Get out of here." Li Shimin waved his hand.

Li Ke smiled and flashed.

Looking at the back of Li Ke leaving, Li Shimin didn't know what he was thinking.

Since he was preparing to leave in a month, Li Ke didn't go to the back to see Concubine Yang or anything like that, and he still had to deal with the things in his military camp, but there were some things that had to be arranged in advance.

Everything that should be prepared is prepared, and the people who should be notified are in place, such as Li Yan and Wu Jue, Li Ke are ready to bring it.

Although the construction of Datang Sleepless City is more efficient with Li Yanzai, it is not a big problem without her, Chang'an City here Tian Meng can call more manpower, and sending more people can achieve similar results.

And Wu Jue's side, no matter what her history is, since she is entangled with Li Ke now, it is estimated that she will not be able to get rid of it in the future, a little girl, take it with her, maybe if she has something she is interested in, you can let her try more, since she can be the emperor in history, no matter what her actual knowledge is, but at least she will definitely be able to use people.

In various industries, no matter what you do, as long as you can employ people, it will not be too bad.

There are not too many talents who can take charge alone, as for Yang Anning, they must also bring it, and his little monk Li Ke has not broken the vows, since he has broken the vows, how can he continue to hold back this matter, a strong young man, of course, he must bring it.

And the rest of the materials and other things, Li Ke directly pulled a list and handed it to Tian Meng to prepare, including informing Yu Wenlin, who is located near the Bohai Sea, to prepare the fleet, and selecting soldiers who are not seasick from the five thousand soldiers currently trained to train with the army, these are all to be carried out.

Naval training has been going on on the Bohai side, and the crew in the early stage must be enough.

In addition, the weapons and equipment to be carried must be prepared, even if you don't go first with Li Ke, you must follow the ship all the way.

The dressing of the sixteen guards of Chang'an is ready to begin.

Leaving the palace, Li Ke returned to the nearest shopping mall, and then called Tian Meng, and then asked him to sort out the delivery records of Yuelai Commercial Bank from Xizhou and bring them to Li Ke.

About half an hour later, Li Ke got the relevant data.

Li Ke has probably seen these data before, but this time he has seen it in more detail, and the materials currently sold to Tubo are about 12,000 sets of Quyuan plows, equivalent to 48,000 taels of silver.

Datang is 16 taels per catty, and one tael is equal to 10 cents. Ten coins means the weight of 10 Kaiyuan Tongbao.

Because money is the most popular, it is easiest to popularize weights and measures with money as the standard.

If calculated in later generations, a catty of Datang is about 600 grams in modern times, and a Kaiyuan Tongbao is about 3.75 grams, that is, a tael of silver weighs about 37.5 grams. That's exactly 18 tons of silver.

In addition, other linen, silk, porcelain, tea, etc., sold a total of 20 tons of silver.

A total of 38 tons of silver were recovered from Tibet, which is not much, but Li Ke knows that this is also because the Tibetan side has just started to act, and the market has not yet expanded so much, and when the market expands, this amount will expand rapidly.

Li Ke pondered for a moment, and then spoke: "Tian Meng, call Ah Shilu over." ”

"Yes!"

A Shilu came very quickly, once as a Turk, although Ah Shilu's current grade is not big, but in his mind, he is already a Han Chinese, and His Royal Highness the King of Qin is his immortal sky.

"The minister has seen His Highness." A Shilu respectfully saluted Li Ke.

"I'll give you a task, you leave for Persia now, I will carry you a large amount of gold, and when you arrive in Persia, exchange all the gold in your hand for silver." Li Ke said.

"I don't know how many Your Highness there are?" A Shilu asked with some confusion.

Li Ke pondered for a moment, how many? If the entire Datang is scavenged and borrowed, Li Ke can probably loot 200 tons, and at present, Li Ke has brought back 20 tons from the Western Regions, counting some gold ornaments in his hand, etc., and then ask his father for some, 200 tons should be no problem.

"More than 3,000 stones." Li Ke gave an approximate figure.
