Chapter 117

Li Luoyang's energy-saving stove hasn't started to be adjusted yet. Ren Haoyun over there has received an order from Chang'an to allow him to act conveniently.

Sometimes the so-called "doing things easily" is actually a standard official tone of the superior. In other words, the success of this thing is the credit of the superior. If it fails, something goes wrong and becomes a moth, it is that the subordinate fails to accurately understand the meaning of the superior.

This is the result of the meaning in Chinese. Not to mention now, even hundreds of years and thousands of years later, the instructions of leaders are often so ambiguous. What to do is the problem of subordinates.

What else can Ren Haoyun say when he sees the "instructions" except a knowing smile? At least this instruction agreed to sign an agreement with Li Luoyang, and Li Luoyang made it clear that he would show his technology to Ren Haoyun only after signing the agreement.

With Shangfang's sword, Ren Haoyun asked Xiaohui to invite Li Luoyang the next day. The reason why he used the word "please" is that when he took office, Hao Yun must treat Li Luoyang as an equal partner and have a good attitude. Only when he signed the contract can he have a good discussion.

"Basically, I have no problem. According to the terms we talked about last time," Li Luoyang was also happy when he came. He got to the point in a few words and then talked about the agreement. Li Luoyang means that this technology adopts the single charge mode. Six doors can't transfer the technology. If six doors need to adopt this technology when handling a case, the use fee is ten Liang silver, but it doesn't mean that ten Liang silver is used once, but the authorization fee for a case.

Ren Haoyun doesn't understand what the authorization fee is. He just doesn't think the price is too deep. As long as this method can lock the suspect at one time, ten liang of silver is often worth it.

Of course, he has another problem, that is, the cost of using this technology. In this regard, Li Luoyang readily told Ren Haoyun that the cost of using this method is almost negligible. Li Luoyang has successfully tested this point. If we have to say the cost, it may be the effort of grinding carbon powder. This is indeed time-consuming, but if it is manufactured in large quantities, the effort consumed can be ignored.

After all matters were settled, the two sides happily signed the contract. Li Luoyang blew the paper and waited for the ink on it to dry before carefully folding it.

"Well, should we start to show your new technology?" Ren Haoyun handed the agreement to Mo Jiao and looked at Li Luoyang with a smile. In fact, Li Luoyang was already ready. As soon as Ren Haoyun spoke, he took out a porcelain vase, a soft brush transformed with a brush, and, of course, a top thin paper, the kind of snow-white.

"What's the use of these things?" Mo Jiao frowned and asked, looking at the things on the table.

"Well, I'll know in a moment. First of all, I want to explain a concept, that is fingerprint."

"Fingerprints?"

Both Ren Haoyun and Mo Jiao seem at a loss. Although fingerprint is the most popular and best means of detection in future detection technologies, everything is new for this era.

"Everyone has their own fingerprints. It can be said that there are no two people with the same fingerprints in the world, so we can take the fingerprints as the most accurate indicator in the process of solving the case. If you don't believe it, you can also compare them."

"Even if you're right, what do you think of fingerprints?" Mo Jiao was still at a loss. In fact, she even doubted that everyone's fingerprints were different. Seeing that she studied her fingers over and over, Li Luoyang smiled faintly and said: "This is the new technology I'm talking about. In short, this technology can rub down the fingerprints left by the suspects at the crime scene. With these fingerprint templates, you can compare them with the suspects you catch. Once the fingerprints match, it means"

"That means it's the real murderer, isn't it?"

"Well, your brain is still very good sometimes."

"I thank you." Mo Jiao smiled proudly at first, and then felt something wrong. Li Luoyang clearly said this with a gun and a stick. Suddenly his face changed color and said, "what is sometimes good? My brain has always been good!"

"But it's easy for an adult to argue with a minor like me? If not, how can I say that your brain has been working well?"

"I"

"All right, all right, Jiao Jiao, don't make any noise. Let's study it first. How should the fingerprints at the crime scene be rubbed down?"

Ren Haoyun handles at least a dozen cases every year. It is difficult to judge the murderer in many cases. Sometimes when the suspect always refuses to admit, Ren Haoyun has to use heavy torture to extort a confession, but in fact, he doesn't like it, because extorting a confession by torture is essentially an insult and a manifestation of lack of wisdom. As a student, he can only rely on brutality Hao Yun, who is unwilling to do so, prefers to rely on evidence and his strict logical judgement to make the suspect love to admit his guilt.

Now the technology provided by Li Luoyang is what Ren Haoyun urgently wants. It can be said that Ren Haoyun has felt that he is right to come to Anning county this time.

If Fang Jie knew Ren Haoyun's idea, he would certainly feel a loss. He should increase the cost of a single authorization by at least 50%. Maybe Ren Haoyun would agree. When liumen finds that the authorization cost is actually very high in the future - maybe someone will worry about whether Li Luoyang can receive the authorization fee, But in fact, Li Luoyang is not worried about this at all. Whether he can receive the money depends not on whether the technology itself is valuable, but on who will collect it.

Perhaps at the beginning, liumen would try every means to refuse to pay, but Li Luoyang believes that one day liumen will admit the fee obediently and even settle it with interest.

"Well, let's start experimenting with how to take fingerprints. Let's take this tea cup as an example. I'll wipe it clean first, and then Ren, please take it."

"Why take it?" Mo Jiao asked incomprehensibly.

"In this way, if I take it, I will leave my fingerprints on the tea cup?" Ren Haoyun's brain is obviously better than Mo Jiao, but he has stared his eyes to the maximum and found no trace of his fingerprints on the tea cup.

"It's impossible to see the fingerprints clearly with the naked eye, so we need to use tools." Li Luoyang ignored Mo Jiao, but took out the porcelain bottle in his pocket, pulled out the cork, and gently shook the black powder in the tea cup where Ren Haoyun's fingerprints may be on.

Here is the moment to witness the miracle!
