In the following time, Li Cao and Feng Wei have been following Baifeng, but Li Cao's whereabouts are well hidden, and Bai Fengwei has not found out.

But after passing the Yumen Pass, Li Cao was not leading Fengwei to follow, first, after passing the Yumen Pass, it was too difficult to hide well in Xiang, second, after this period of observation, Li Cao did not find anything abnormal, and third, with Mingwei's intelligence network, Li Cao learned that she was about to reach the northwest battlefield, and she also had to speed up her pace.

So she led Feng Wei forward first, and sent orders to Jebe and the others, asking them to speed up as well.

"Xuan Ce, look at the information sent by His Royal Highness, your little sister-in-law is really not an ordinary person, so she ran out with her own troops" At this time, Xue Rengui, who had already rushed to the original Qiuci Country and was now repaired in Qiuci County, said to Wang Xuance, who had just come in.

"What, this girl ran out and wanted to go to the battlefield, isn't this nonsense? Your Highness, how could he agree" Hearing Xue Rengui's ridicule, Wang Xuance hurriedly took the information and looked at it, and said in surprise.

"Do you need to be so surprised? Although I don't know what His Royal Highness is thinking, but in terms of that girl's ability, what's wrong with going to the battlefield, don't forget, this girl can be regarded as you and me, and there are many veterans who have taught her, you don't know what she can do, so it's not a big deal for her to come, just take some necessary precautions" Xue Rengui saw that Wang Xuance was so excited, so he said with a smile.

"If you say so, that's right, but we still have to guard against it, this girl goes to the battlefield privately, I see, just hand over the defense line of Taku Town to her and her Baifengwei, which is not the center of gravity of the Western Turkic defense line, what do you think" Wang Xuance finished speaking, looking at Xue Rengui.

"Taku Town, I'll take a look, but I can, but I'm afraid of the Western Turks, if I want to go east, or flee west, it's the only way to go, I'm afraid of ........."

"You're too unconfident for us! This time, our army will go on the expedition, do you think the Western Turks still have a chance? Of course, you have a point, it is indeed an important place, but I suggest that the girl be left there, and an army of 10,000 people should be sent to garrison it 50 miles from the town of Taku."

"Let's talk about that! Specifically, when we go over, let people see on the spot, we are making decisions, but compared to Taku, I am more worried about this, this is a no-man's land, but through the no-man's land, the Western Turks can directly bypass all the current defense lines of my Datang and enter the current Qinghai County, so we have to put an army there" Xue Rengui pointed to an inconspicuous place on the map.

When Wang Xuance saw it, he also hurried to look at it in front of the map, and then the two discussed.

At this time in Chang'an, Li Chengqian was also discussing with Li Wei.

"Sister, what you said, the matter of non-local transactions, it is not impossible to solve it, as long as there is the imperial court to take the lead, it is not enough to directly set up a money bank for people to deposit and withdraw money" Li Chengqian directly said lightly after listening to Li Wei's situation on the existing business, the difficulty of trading in different places, and the fact that you have to bring a lot of money to buy things every time.

was given an understated answer by her younger brother, Li Wei was a little angry at first, but after all, she had managed the Chamber of Commerce for many years, and she still quickly grasped the point.

"Gao Ming, what is this bank, what is the deposit and withdrawal of money, and how to complete the operation in it" Li Wei asked Li Chengqian with a puzzled face.

For example, if you take the money and go to the bank to deposit the money, the money bank will issue you a deposit certificate with a special mark and is difficult to be counterfeited, this deposit certificate can be a hundred dollars, or it can be said to be 100,000 yuan, millions of money, this depends on how much the person who saves the money, and as long as the person who holds this deposit receipt, he can go anywhere As long as there is a money bank, he can take out the money with this deposit receipt, so that it can solve the problem of difficult transactions in different places." Li Chengqian simply told Li Wei what the money bank was like and the process of realizing the transaction in different places.

"But Gao Ming, according to what you say, this money village is really a good thing, but there are still a lot of problems, you are how to do this deposit certificate can not be counterfeited by others, and the issuance of the deposit certificate is as long as there is money can be village, or there is still an identity certificate, after the deposit certificate is damaged, can you still take out the money, or whether the deposit certificate must be taken by the person who saved the money, have you ever thought about these? And ........." Li Wei asked Li Chengqian a lot of questions in one breath.

"Sister, sister, sister, you wait a minute" Seeing that his eldest sister was still going to ask, Li Chengqian hurriedly stopped "these specifics, how do I know, I don't specialize in this, you really want to get money, you directly find some people who are particularly good at arithmetic, and some businessmen, legal talents, you discuss together, discuss a set of plans that conform to the law and are practical, and then according to the general plan, subdivide all the details."

"You're right! Then why am I wasting time with you here, you are really useless" After speaking, Li Wei left directly.

Watching his eldest sister leave, Li Chengqian laughed, he also thought about the money bank or the bank in his early years, but at that time he thought it was too complicated, and the business had not developed to that point, so he didn't do it.

But he also wrote a plan based on a simple understanding of the bank in his previous life, originally Li Wei only talked about the difficulty of trading in different places, and his sister wanted to drink Li Wei to talk about it, but then I thought about it, instead of saying everything myself, it is better to let Li Wei find someone to discuss, and maybe I can come up with a banking system that is more in line with the current national conditions of Datang.

But Li Chengqian still did some of the preparations in advance, such as asking the Academy of Sciences to develop better paper than it is now, and asking Mocheng to come up with a set of strict anti-counterfeiting standards according to his needs.

These were done a few years ago, and paper in particular has come a long way.

Li Chengqian was reluctant to do it because he found that he was too good at finance, and he was afraid that if he found it, he would exaggerate the economy that Datang had developed without easy development.

Although it is said that even if it collapses, it will be fine, in this era of the supremacy of imperial power, it is really collapsed, kill a few people, re-enact a new law, and adjust taxes.

But Li Chengqian didn't want to do this, so his sister put this matter aside.

Thinking that there will be more talents in the future, especially in arithmetic, he is doing it.

But now that Li Wei has proposed it, let her get it first, if it comes out well, then use it, if it doesn't work, then wait, anyway, he can't remember it.
