Tian Baojiao's counterfeiting technique started from the source, and he had something called "stone paper" in his hand, which was, in our current words, a pressure-sensitive material.

When every guest came to their bank to deposit money and get a silver ticket, he signed the contract on stone paper. No matter what kind of signature and drawing your signature is, the stone paper is clearly recorded, as long as a cloth dipped in a specific potion of stone paper, it will show the traces of the guest's signature and drawing.

Therefore, Tian Baojiao has a second copy of the silver ticket that every guest gets here, and he takes this second silver ticket to buy things, and with this, his Tian Baojiao's wealth can come out of thin air.

Some people may ask, didn't the silver ticket he opened ask Tian's money bank to redeem it? Not necessarily, at that time, several major money banks jointly issued a joint bank ticket, and one ticket was exchanged, so his expenses were basically all the money banks were helping him pay for it. This kind of thing will not be noticed until it breaks out on a large scale.

This kind of counterfeiting technology is the only one in the world, and no one else knows, and the people in the money village only know that the shopkeeper requires every guest to sign on the paper. Moreover, the pad paper is a guest and must be stored in a specified box after use, which is the rule of the money bank, and no one has ever doubted it.

The reason why Tian Baojiao is not afraid of others knowing that he is fake is because he has the recipe of the potion that can make the stone paper develop, and every time he uses it now, he destroys it when he runs out, so it is impossible for others to find traces from the stone paper.

This Tian Baojiao is really a clever liar, he knows that his technology is impossible to be discovered, so when people say that he is fake, his first reaction is to be wronged!

Feng Qiansheng couldn't tell that there was anything wrong with Tian Baojiao's expression, but his intuition felt that this person was not telling the truth, so he tried his best to find out whether Tian Baojiao was cheating.

After thinking about it, he decided to start with the second shopkeeper of Tian's money bank.

The second shopkeeper has been released a long time ago, but Tian Baojiao's arrest has greatly affected the business of Tian's money village in the capital, and he also looks forward to Tian's shopkeeper being released as soon as possible.

So when Feng Qiansheng explained his intentions, the second shopkeeper was very willing to cooperate, and he told Feng Qiansheng about the rules of Tian's money village for daily exchange of silver tickets.

Feng Qiansheng has never managed Qianzhuang, so naturally he can't hear the doorway here. But he took a piece of paper and wrote down the rules in detail, and later he inquired about a few banks, asked them in detail about their operation, and recorded the process.

When he returned home, he compared the process of all the money banks, and found that Tian's money bank had the problem of pad paper.

He went to the money bank repeatedly, and finally determined that other money banks did not have this program of paper padding, and his intuition told him that there must be a problem here, but where is the problem?

He asked for a pad paper to study in detail, but there were no problems in the study. Every day after eating, Feng Qiansheng sat in the room and looked at this pad paper, thinking about all the possibilities, he also thought about whether this pad paper has the function of copying, so he also put the pad paper on the paper and pressed it hard, hoping to press out the ink hidden in it, but there was no result.

Yintian looked at him mysteriously every day, and felt curious, so he secretly observed him, and saw him staring at a piece of paper on the table in a daze every night, Yintian finally couldn't help it: "Big brother, I see you staring at that piece of paper every night, is that paper so good-looking?"

"Alas, second brother, I don't know why, I always want to find evidence to prove that Tian Baojiao is actually fake, but I can't find any evidence. ”

"Then don't look for it, maybe the shopkeeper Tian is really not fake?"

Feng Qiansheng was very stubborn: "No, I don't think he is telling the truth." Second brother, come on, what's wrong with this piece of paper?"

Yintian walked over and touched the paper: "It's a little harder than other papers." As he spoke, he folded the paper.

Feng Qiansheng didn't expect him to be so reckless, so he hurriedly took the paper over and flattened it, but found that the creases left by the paper after it was folded seemed to be more obvious.

He tentatively folded it again in the corner of the paper, and after flattening it, the crease was indeed deeper.

Feng Qiansheng was excited, and hugged Yintian: "Second brother, you are my lucky general, come and see, is the crease of this paper a little deeper?"

Yintian echoed Feng Qiansheng: "Yes, yes, it's deeper." ”

But something even stranger happened, this crease actually disappeared slowly, Feng Qiansheng felt a chill on his back, and Yintian asked him: "Big brother, what do you want?"

"Don't speak, don't talk yet!" Feng Qiansheng signaled Yintian to shut up, he thought in his heart, the crease was very deep, but it gradually disappeared, there was something wrong with this paper. If the imprint is imprinted, it will definitely disappear slowly, but is there a way to make the printed handwriting reappear?

Feng Qiansheng immediately dipped a little water in the teacup with his hand, and gently smeared it on the crease just now, but there was no reaction, and then Yintian saw that Feng Qiansheng applied some water for a while, and some wine for a while, what hot water, hot wine, hot tea, vinegar, soy sauce...... As long as it was liquid, he painted it on paper, but there was nothing.

Feng Qiansheng applied all the liquid he could find for several days in a row, but the result was nothing.

He didn't give up, he knew that there must be something wrong with this paper, there must be something that could make it show the creases again!

After a period of tossing, Feng Qiansheng completely surrendered, and he knew that this liquid that could make paper develop could only be known by Tian Baojiao.

So he took the paper and went to see Tian Baojiao in prison.

Jing Zhaoyin saw him change his politeness this time, and first avoided it, so Feng Qiansheng had to find Cao Qiu to put pressure.

When Jing Zhaoyin was finally willing to see Feng Qiansheng, he shirked and said that Tian Baojiao had been sick recently, and he would meet Feng Qiansheng when he was well.

Feng Qiansheng looked at Jing Zhaoyin's meaning and seemed to have an inside story, so he went to Cao Qiu again, although Cao Qiu felt a little impatient, but he also sent someone to follow Feng Qiansheng and finally said that Jing Zhaoyin let them in to see Tian Baojiao.

When Feng Qiansheng entered the cell, Tian Baojiao was lying on the bed with his back to them.

"Brother Tian!" Feng Qiansheng shouted.

Tian Baojiao didn't react.

Feng Qiansheng and Yintian stepped forward and turned Tian Baojiao over, he was unkempt and smelly, Yintian and Feng Qiansheng couldn't help but fan the wind with their hands.

Feng Qiansheng shouted again: "Brother Tian!"

Tian Baojiao still didn't react.
