No wonder Li Yi's heart shook, membership card, that is something related to the lifeblood of Datang's economy, because it involves an extremely important concept in the financial field - virtual currency.

Like the Jinding membership card of the Jinding coin, once popularized, it is likely to replace the physical copper coin to a certain extent, in the development of the paper money era, once the paper money era comes, the economic system of Datang can be regarded as the real beginning of take-off.

And now, the paper money system of the Tang Dynasty is still in its infancy, and it will take a long way to succeed, even if it only hits the silver ticket era of the Song Dynasty, it will take at least ten years.

The key thing is that the basis of this is the membership card system and membership card currency, which is a chess piece of Li Yi and an important lever to pry open the era of paper money.

Li Yi is worried that he doesn't know how much the Maison has learned about the membership card system, and if they realize the importance of virtual currency, it will be really bad.

Fortunately, the emergence of banknotes represents the progress of the times, which is not so easy to understand, and he has not heard of the family meddling in the bank, as long as there is no money, the so-called virtual currency is just rootless duckweed, without any deterrent.

"Brother?"

Li Yi was thinking about it and was interrupted by the impatient Shangguan who was already waiting on the side.

Li Yi came back to his senses suddenly, looked at the same eyes of the people around him, and smiled dryly, which could be regarded as blocking the past.

Then Li Yi didn't ask too much, and asked Lu Ming to pay for a hundred taels of silver cakes and teach them to the maid.

The maid took the silver cake and began to help Li Yi with the formalities very skillfully.

Although there is a money bank, gold and silver are not yet the currency in circulation, but they have the ability to buy goods, and in some large stores, you can pay for silver cakes directly, but these silver cakes must be specially made by the money bank.

This is the business that Qian Zhuang has only recently started, and it is also Li Yi's vision.

Qian Zhuang collected a batch of gold and silver, and then made a silver cake with the seal of Qian Zhuang in accordance with the unified regulations, these silver cakes can be used directly as currency in some large stores, these shops have also been trained by Qian Zhuang, with the ability to distinguish between the real and fake silver, and, once the counterfeit money is found, the government will immediately accept it, and serious cases can be directly imprisoned and punished, so, so far, there are few frauds, of course, there will definitely be a risky existence, but most of these people have been punished by the law, Only a few were lucky enough to escape, but they also lived like lost dogs.

However, this monetary system has many restrictions, so far, it is only available in the vicinity of Chang'an and Luoyang, as well as in some high-class state capitals, and most of them are only popular among high-class nobles and wealthy merchants, after all, ordinary people estimate that all the worth is not worth a tael of silver.

The procedure is quick, but it takes time to make a membership card. Li Yi is not in a hurry, do a good job of registration, and then receive half of the carved seal, in the Huangquan Tavern, every customer will be issued half a carved seal and a personal maid, all the entertainment activities in the tavern need half of the engraved seal in the hands of the customer and half of the carved seal in the hands of the maid together, in order to register successfully, and then you can enjoy the fun, the expenses incurred will be settled at a fixed time every day.

This system is the first of its kind in Huangquan, because Jinding does not yet have a comprehensive tavern like Huangquan. From this, Li Yi also secretly reflected, he was still short-sighted, and actually forgot the benefits of this total comprehensive ***, fortunately, the shops of Jinding are generally gathered together, and all the systems are unified and universal, and the comprehensiveness of Huangquan Tavern has the same benefits, and it is not too much of a loss.

Li Yi received two engraved seals, gave one to Shangguan, kept one for himself, and then asked Shangguan to take the engraved seal to have fun by himself.

Shangguan was a little embarrassed at first, but later, under Li Yi's urging, he twisted and agreed, in fact, the main thing was that he saw that Li Yi took out a hundred taels of silver cakes without blinking his eyes, and he knew that Li Yi was a real tyrant, not bad at all, and he was not a pretentious person, so he did not plan to save money for Li Yi.

After Shangguan left, Li Yi also came to the Huangquan Tavern, which was a real tavern and belonged to part of the Huangquan Wine City, and the place agreed by Li Yi and everyone was here.

Li Yi also sent Lu Ming out, and now he suddenly found that he seemed a little simpler at the beginning, they thought that the Huangquan Tavern was so high, and ordinary people would not come to such a place, so the so-called joint was really difficult.

But Li Yi did not change his decision, although it is difficult to enter the tavern, as long as he can enter, he is definitely an elite, at least in some aspects, he is very outstanding. Therefore, Li Yi also regarded it as a test for them, and Li Yi decided that anyone who could enter the inside of the tavern would be the core seed of the Ministry of State Security in the future, and those who could reach the outside of the tavern would be the second echelon, that is, the elite seed.

Li Yi was drinking wine and tea in the tavern, and since he had rested during the day, he was not sleepy now.

After sitting for about half an hour, Li Yi felt a figure swaying in front of him, and when he looked up, he saw Fu Qing standing in front of him with a slightly tired expression, with a look of shame that he couldn't hide.

"Hehe, here? Sit! ”

Fu Qing's expression was slightly decadent, a little discouraged, and he sat down sullenly, lowered his head, and did not speak.

"What? Hit by it? ”

Fu Qing was still immersed in the shadow of the failed gambling contract, so he only nodded stiffly at Li Yi's questioning, and he still didn't understand how he was discovered.

"What, can't figure it out?"

Fu Qing nodded sullenly again, but this time he raised his head and stared at Li Yi with his eyes, wanting to know the answer that had been bothering him.

Li Yi took a sip of wine and ate another bite of food, and then replied faintly: "Actually, it's very simple, these people will have talented skills, like me, they are more deaf and clear than ordinary people, and the doorman is the same, his hearing is abnormally developed, and he can hear very subtle sounds, so he will keep his eyes closed, as if he is asleep, in fact, she is listening to the sound with her heart, because, in such weather, it is more useful to close her ears and eyes."

Therefore, no matter how well you hide it, you can't help but make a sound, and even if you don't think about it at all, it's normal to be discovered! ”

After hearing this, Fu Qing suddenly became sudden, his eyes lit up, his heart felt suddenly enlightened, and the knots in his heart were finally unraveled. Still, he had doubts.

"How did you know, Grandpa?"

"Intuition!"

Fu Qing's eyes were dumbfounded.

Li Yi grinned.

"Well, there are still some observations and speculations, and my eyesight is relatively good, so I have seen that the guard has obvious vigilant movements when we are approaching, and besides, he seems to be lazy, but in fact his body has always been in the best state of attack, and the posture he has made can make him enter the battle state in an instant. So, I guess he's not as simple as it seems. ”

"That's all?"

"Then what else do you need, it's a gamble, if I'm completely sure, I'll let you take the risk? Compared to the mission, you think I'll care about this little bet? Bet with you, just to get you to test him! ”

After hearing this, Fu Qing immediately bowed to him, his status is different, the angle of the problem he considers is also different, and his realm is different.
