Sima Ruanqing's eyes did not leave the mirror, and he explained casually: "Exactly, through this thing, the extremely small part can be magnified, and some traces can be judged more clearly." ”

After listening to Sima Ruanqing's words, not only Yu Ji'an and the case guard, but even Yang Heng and Luo Lie on the side were also a little curious, only Wang Jin had already seen Sima Ruan Qing demonstrate all kinds of wonderful crafts in this box, and he had tried it himself, so it was not too novel, just waiting for the results after Sima Ruan Qing checked all the traces.

Although Yu Ji'an and the case guard wanted to ask again, they saw Sima Ruanqing's solemn expression and knew that it was inconvenient to say more at this time, so they all stood aside and watched quietly.

Sima Ruanqing's eyes continued to observe the broken gap, looked at it for a long time, did not speak, just shook his head, and then picked up the half-bitten martial arts pill to look, and also looked at it for a while, and finally shook his head.

Sima Ruan Qing didn't speak, and the others didn't say anything to ask, just watched her busy.

After seeing the martial arts, Sima Ruan Qing put the light mirror that could magnify the details back into the wooden box, and then took out a handful of strange soft clay from a box in the wooden box, rubbed it slightly in his hand, and then smeared it on the broken mouth of the pill bottle, and then wrapped the excess soft mud around the half of the martial pill.

Except for Wang Jin, no one knew what Sima Ruan Qing was doing, and they all looked at it curiously.

After waiting like this for about a while, Sima Ruan Qing suddenly picked up the spirit yuan, and carefully and subtly probed the spirit yuan into the soft mud, but did not touch the pill bottle and martial arts wrapped in the soft mud.

Everyone could see that Sima Ruan Qing's use of Lingyuan had reached the realm of perfection, so delicate and light. It is very subtle indeed.

After about a moment, whether it was wrapped in a pill bottle casually with soft mud. The soft mud that was still wrapped in Wudan automatically fell off. It fell into Sima Ruanqing's hands, and it was obvious that the soft mud had become a hard mud block, and the part that was wrapped in the broken mouth in the middle was dented.

Sima Ruan Qing just took a brief look, and then handed over two hard pieces of mud, one to Yu Ji'an's hands, and the other to the case guard, the meaning was obvious, while investigating the case, while looking at their skills. It can be regarded as giving them a taste of the usefulness of this ooze clay.

"Huh?" Yu Ji'an was less than nineteen years old, he was a young man, he couldn't hold his breath, and when he saw the hard mud depression, he couldn't help but speak: "Isn't this depression the tooth marks, which are more ......delicate than the magnifying glass" As he spoke, he thought for a moment and said, "Why don't you imprint all the casual impressions into the mud, and only imprint the tooth marks?"

"Ji'an. That's so much. The case guard looked at the hard mud in his hand and looked curious, but after listening to Yu Ji'an's words, he was afraid that the Great Sect Xi Sima Ruan Qing would be impatient, so he scolded him. Although they have only been together for more than half an hour, he has already regarded Ji'an as his apprentice in his heart.

"It's okay, that's all this expedition can do. I can't find many clues. Sima Ruan Qing smiled lightly, and turned to Ji An: "This mud is skillful." It is the automatic detection of traces of the action on the object outside the wrapped object, the crack of the fragment. It was originally on the pill bottle, and the desolate beast bit the pill bottle, and this soft mud could print the traces of the objects acting on the pill bottle, and in the same way, if other swords cut the pill bottle, he could also print the traces of the sword. ”

Yu Ji'an saw that Sima Ruan Qing didn't mind, and his heart was excited, but after listening to the explanation, he had new questions, so he simply asked together: "Great Teaching, what kind of truth is this, isn't it immortal art?"

"Reading is dead. The case guard understood, although Sima Ruan Qing didn't mind, but he couldn't always let Yu Ji'an keep asking like this, and explained for Sima Ruan Qing at the moment: "How can it be immortal art, this is the magic of craftsmanship." For example, if you bite a piece of wood with your teeth, the tooth marks will leave the things that make up the teeth, but they are just invisible to the naked eye. ”

Yu Ji'an was not stupid at all, the case guard explained so, and he nodded again and again: " I understand that when the teeth are ground up, they are the powder, and those are the things that make up the teeth, and the beast bit the bottle, and we can't see any damage to his teeth, and he himself can't detect any damage, but in fact, there is a complete tooth powder left on the bite marks, and after the soft mud wraps the object, it can automatically recognize what is still left on the object except for this object, so it completely imprints the traces of the tooth powder, that is, the shape of the tooth marks, and puts aside the cracks of the medicine bottle itself. ”

Sima Ruan Qing nodded and said with a smile: "You can understand it so quickly, it is indeed rare, you can look at the "Ten Thousand Things" written by the sages, which says that things collide, although they are invisible to the naked eye, their quality will melt." ”

"It's too complicated, and if you don't learn how to solve cases, it's useless to know. Wang Jin couldn't help but interject a sentence and said: "When I tried to use this soft mud, I heard Sima talk about what kind of things are combined, although I understood it, but I still felt that it was too magical, as if my two fingers touched each other, in fact, the flesh that made up my finger has been fused with the fine meat powder in the meat of that finger, but it is not what our eyes can see." ”

"Can even the meat powder of your fingers be printed?" Yu Ji'an said curiously.

Sima Ruanqing just smiled and shook his head again: "No, if you can, this soft mud is really magical, it can only be printed with traces after hard objects are buckled together, such as knife cutting, such as tooth biting, if you just touch this porcelain bottle lightly with your teeth, the soft mud is impossible to distinguish, and there will be no mark." ”

Yu Ji'an said "oh", only to feel that what he heard today was unbelievable, in fact, it was not just him, Luo Lie and Yang Heng were also average, but he didn't open his mouth to ask, Luo Lie didn't want to interject and disturb Sima Ruan Qing, Yang Heng knew that if he asked, he would be snubbed, so it was better to just listen and not ask.

Although Yu Ji'an understood what it meant to be a fusion of things, he couldn't imagine it like Wang Jin, and then he was about to ask, but he heard Sima Ruan Qing say: "This thing is blended, and I can't figure it out, I can only understand what we see, like the traces of this hard object after impact, that light touch, can also blend together, I can't explain it to you, I only know that it is written in the scriptures of the sages, according to the traces that can be identified by this soft mud, it should also be reasonable." ”

Yu Ji'an wanted to get a deeper answer, but after listening to Sima Ruanqing's words, his expression was slightly disappointed, but he immediately thanked him again: "Thank you Dajiao Xi for teaching me so much knowledge, Yu Ji'an is grateful." ”

With a deep bow as he spoke, Sima Ruan Qing stretched out his hand to support Yu Ji'an's wrist, and helped him up with a force, "Don't use so many etiquette, hurry up and take a look at this bite mark, can you see anything?"

The case guard on the side had already carefully looked at the hard mud in his hand, and already understood what kind of beast caused the traces, and when he heard Sima Ruan Qing ask, he also went to look at Yu Ji'an, only hoping that this disciple could answer, although he could answer it, it was not taught by him, but the case guard felt that the disciple was smart, and he also had a long face in front of the great sect.

"Hmm...... This tooth mark seems to be that of a giant tortoise. Yu Ji'an flipped left and right, and after carefully looking at the tooth marks on the hard mud, he immediately spoke: "I have hunted every desolate beast in the territory of the desolate beasts, and I will observe their structure, and I remember that the one that can bite these tooth marks is unique to turtles, and judging from the appearance of the shards, it should be a tiger tortoise." ”

"That's right. The case guard also nodded: "It's just that there are many kinds of wild beasts, and the mixed blood wild beasts have become very strange, and it may not be able to conclude that it is a tiger tortoise, but it can only be determined that it is a turtle with a large body like a tiger tortoise. ”

"The case guard is right, you will worship him as a teacher in the future, but you should learn more from him. Sima Ruan Qing smiled and nodded.

Then his face turned cold again, and he said to Wang Jin: "I can only do this, the one who came to Yang Heng to destroy must be a giant turtle, but I still don't understand how such a giant turtle came into this courtyard, and Yang Heng didn't notice it at all, and asked Senior Brother Wang to send the law camp guards to search the whole city under martial law, such a big turtle can't just disappear so inexplicably." ”

Wang Jin nodded, also with a solemn face, and turned to Luo Lie and said: "General Luo Ying, this matter will be handed over to you, and I will also report to the chief teacher, and the investigation camp will be with our law camp." ”

"Obey the orders of the general teacher. Luo Lie gave a fist salute and asked, "Can you set up two secret sentinels outside Yang Heng's courtyard, whether this turtle has spiritual wisdom or not, it just found Yang Heng here to destroy, and it may also be here to seek revenge." ”

"It's fine. Wang Jin nodded: "But there may be very few revenge searches, such giant tortoises sneaked into our beast extermination camp, and were not discovered, they should be walking at will, or seriously injured, find Yang Heng here, see that there is an elixir, so he ate it all, and a few half-pills of martial arts fell between his teeth." ”

"That's right. Sima Ruan Qing also nodded, and said: "Devouring the Martial Pill like this, there should be no spiritual wisdom, otherwise you must know that eating the Martial Pill like this, even if it has the Beast Pill to carry, it can't help the evil spirit of so many Martial Pills." ”

After hearing this, Luo Lie patted his head and shouted: "Yes, such a simple truth, I didn't expect it, I must have just thought about the integration of things and things, and my head was dazed." ”

"Don't come to me to laugh, let's go. Although Wang Jin is calm, he has a very good relationship with subordinates like Luo Lie, and he gets along relatively easily: "Transferring the secret sentry is also to guard against the special habits of the wild beast, and likes to revisit the places where he has been, and he has swallowed so many martial arts, he should have been injured, and he will hide somewhere at this time." ”

"What the Great Sect said is reasonable, so I'll go. Luo Lie hugged his fists again, turned around and left. (To be continued......)
