Zhang Lei was a little confused by the second monk and asked: "What do you want tiles for?

And he also asked the voices of everyone present, what are you doing so mysterious?

Du Jing pointed to the tiles on the roof and said: "The glazed tiles that have been nurtured by the teachings of the Soul Worship Sect every day have become spiritual, and they can distinguish people who are not respectful, righteous and shameful, and theft is the people who are not honest and shameful in the Spirit Worship Sect, Brother Siwei, what do you say in your teachings?"

Bai Siwei hurriedly continued: "If you are not honest, you will take everything, and if you are not ashamed, you will do everything!"

Du Jing smiled: "That's right, but you don't need to worry too much, this glazed tile has limited spirituality, and it can only screen out the impolite and shameful behavior for a period of time, and you don't have to worry about being seen by the glazed tile for what you did before." ”

When Du Jing said this, many monks were relieved.

Instead, Bai Siwei pulled Du Jing aside and whispered: "I read that your method has been recorded in ancient books.

In ancient times, there was a theft case in Pucheng County, and several suspects were caught, but no one admitted it. The prefectural ordinance says that there is a grandfather clock that can identify suspects, and that a person who steals something will make a sound when he touches it.

Then the bell was covered with a curtain, and someone was secretly sent to paint ink on the bell. After a long time, the suspects were asked to touch the clock one by one, and then they were examined after touching, and only one person had no ink on his hand, and it was this person. ”

This allusion illustrates how criminal psychology was used to solve crimes when the ancient technical conditions were not good.

Du Jing obviously knew about a similar case, but he was just borrowing a shell.

"Brother Du is going to use this method to screen out the suspects? I think that the records in the ancient books may have some effect on those who fear God and Buddha, but it has no effect on these monks at all, and they don't believe in the teachings of our Soul Worship Sect at all!"

Du Jing patted Bai Siwei's shoulder and said, "If you want to go, you can go, don't worry about anything else." ”

"Do I still need ink?"

"They're not blind, they don't need to paint! By the way, there's no need to remove the tiles of your house, just buy some new ones outside. ”

But in a moment, Bai Siwei returned with the sword, piled a pile of glazed tiles on top of the case, Du Jing took out a piece of dehydrated wet cloth and took out a glazed tile to wipe it and asked, "Who will come first?"

"I'll come first! I really don't believe that this Worship Sect tile is so godly!" Zhang Lei walked up to the stage with a big grin, pressed his hand on the glazed tile, and glared for a long time before asking, "I'm not a thief, am I?"

"The results will be revealed!" Du Jing dismissed Zhang Lei, took a brush and wrote Zhang Lei's name on the tiles, and then shouted to the crowd: "Next!"

In fact, Du Jing's meaning is obvious, he is just to take the fingerprints of the people present!

It's just that these monks don't know the uniqueness of fingerprints at all, so they can only be at the mercy of Du Jing, and it is not surprising that they are still ridiculing the tiles of the Soul Worship Sect one by one.

Finally, even the caretakers, craftsmen, and cooks of the Ministry of Industry have pressed their handprints one by one, and basically all the handprints have been completely collected.

At this time, the big guy was already impatient to wait, and Wang Zhishuang couldn't help but say: "Du Jing, have you finished playing this trick, are you afraid that you will treat everyone as fools?"

Du Jing smiled: "Don't panic, don't panic, these glazed tiles are about to speak!" Qin Shilang arranged for people to boil this pot of kelp, and smoked these tiles with the heat of boiling kelp soup, pay attention to clamping the tiles with tongs, don't hold them with your hands, this will make the tiles fail!"

Can the hot smoked tiles of kelp soup make these glazed tiles speak?

Are these tiles so magical?

Even the cook who makes the fire is full of doubts about this, and no one will believe that a tile can speak.

The cook set up the stove and the iron pot in the hall, and poured the bucket of kelp into the pot, and in a short time the pot of thick kelp soup was already steaming.

According to Du Jing's command, the cook erected the tiles with tongs and fumigated them on the steaming heat.

Not long after, the tile with Zhang Lei written on it gradually showed a yellow-brown palm print under the steaming steam!

"Take the colored dye, and go through the dye!"

Dye is also very common in the manufacturing department, and soon the craftsman came running with a bucket of dye, and after the tile was dipped in cyan dye, the yellow-brown palm print was clearly fixed to the tile by the kelp, and finally showed a blue-yellow pattern.

"This ...... This is my handprint?"

Zhang Lei's eyes widened as he looked at the strange reaction that happened in front of him, and for a moment he really felt that this was the tile of the Soul Worship Sect manifesting.

This is the earliest iodine smoking method used in the fingerprint fumigation method.

It is the use of iodine crystals to heat to produce vapor, which reacts with the grease of the fingerprint residue, and yellow-brown fingerprints will appear, which must be immediately photographed or chemically fixed;

Du Jing didn't know if there were iodine crystals in this world, but he knew what seafood such as kelp had the highest iodine content.

Boiling water is bound to contain iodine-containing vapor, and without a camera, De Regent had to use the primitive chemical method of dyes to fix fingerprints.

The reason why the glazed tile was chosen is entirely because the glazed tile has a smooth surface and is very easy to leave fingerprints.

After fixing all the fingerprints of each person's fingerprints, Du Jing took out the glazed tiles that he had just taken off from the roof and wrapped them in steps.

"This is the tile that has been left on the roof, and I ask the master to smoke this again. ”

As the kelp soup was smoked and the color of the dye was fixed, four relatively clear fingerprints appeared on the inner wall of the glazed tile.

The suspect must not have completely removed the tiles from the entire palm of his hand, but just reached out and moved it away, so it should be normal to leave four fingerprints.

These four fingerprints are not too complete, but it should be obvious that they are the four fingers of the right hand except for the little finger.

Du Jing had even made up the action of the suspect reaching out and moving the tiles.

Although the four fingerprints are incomplete, the largest contact surface is the middle finger, which can basically see the shape of a bucket.

As long as you exclude the people who don't have a bucket with their middle fingers, the rest can be compared one by one.

At this time, the people in the audience looked at the incredible hand prints on the glazed tiles, and their hearts were horrified, could this really be the reason for the Worship Spirit Sect tiles?

Can it really identify suspects?

However, there are also smart people who saw the reason and said disdainfully: "Du Jing, you just want to compare our handprints with the handprints of the tiles!"

But aren't the hand prints just buckets and dustpans? There are many people who fight, and they can't all be suspects, you see my hands have ten buckets! Am I the most suspicious?"

The world does not know the common sense that fingerprints are unique, they just know that fingerprints are immutable for life, so they often use them on signature and drawings.
