Long Zhennan looked in the direction that Mr. Liu pointed, and saw that there was artemisia grass that had been cut in front of him. The stubble of the artemisia grass is uneven, and no one will pay attention to these details unless you look closely.

Then Mr. Liu continued: "Dragon helmsman, look, what is the difference between the broken wound of this artemisia grass?"

Long Zhennan bowed and looked back and forth for a long time, but he didn't see any difference between these fractures. Then he set his eyes on Mr. Liu, waiting for Mr. Liu to answer for him.

Mr. Liu squatted down, pointed to the fracture of one of the artemisia grasses, and said, "Dragon helmsman, look, the angle of the fracture of this artemisia grass. ”

After attracting Long Zhennan's gaze, Mr. Liu pointed his finger at the broken edge of another artemisia grass. He said, "Look at the angle of the break between this and Artemisia. See how these two breaks differ?"

After repeated comparisons, Long Zhennan returned: "One fracture is steeper, and the other is gentle." ”

Hearing such an answer, Mr. Liu stroked his beard and said, "When cutting grass with a knife, there are generally only two ways, one is from the inside out, and the other is from the outside in. Either way, the fracture will always be angled. Unless you have excellent knife skills, you can lower your body and slash horizontally. Such a fracture is smooth. Therefore, the slope is large, and the slope is short. ”

Next, Mr. Liu used his fingers to draw two areas for Long Zhennan. He said: "There is a clear difference between the two areas where Artemisia breaks are. One starting point is high, the other is low. Looking at the whole area as a whole, there are only these two kinds of starting points. This also shows that at least two people are mowing the grass. ”

Long Zhennan couldn't stop nodding, but he was thinking about it in his heart. "One tall and one short, there are no such characters among the enemies of our Long family. ”

Later, Mr. Liu continued: "What do you think these fallen artemisia grasses are connected by the cracks at their fractures?"

Long Zhennan stretched out his hand to draw, and when the trajectory of his finger returned to the original point again, Long Zhennan shouted: "Footprints, these are the footprints of the murderer." ”

Mr. Liu smiled, but Fang Ze and Song Heng were so shocked that cold sweat oozed from their backs. Fang Ze hurriedly sent a message to Song Huan and said, "Senior Brother Song, you will slowly withdraw in a while and wait for me in the woods." We can't go together now, although they don't know who we are, but it's easy to suspect by looking at our figures. ”

After a few minutes, Song Huan quietly withdrew from the crowd and cautiously submerged into the woods. Now only Fang Ze is left at the scene, hidden in the crowd.

Fang Ze continued to secretly observe Mr. Liu and Long Zhennan, eavesdropping on their conversation.

At this time, Long Zhennan asked: "Mr. Liu, with only such a little clue, how can you find the murderer?"

Mr. Liu stretched out his hand, stood in the air with three fingers, and said: "Generally, the case is investigated in three directions, the first corpse, the second scene, and the third is the itinerary and interpersonal relationship of the deceased. We don't have a body now, but we can find some traces from the scene. This figure is only one of them, and the second is that we have to look at the traces of the fight at the scene. ”

Long Zhennan nodded in agreement.

Mr. Liu stood on the brown and black ground and asked Long Zhennan, "Lord Longrudder, don't you feel that this scene is a little abnormal?"

Long Zhennan was strange, standing next to Mr. Liu, and also looked at the surrounding scenery. When he saw such a scene, he didn't see anything else in his heart except sadness.

Mr. Liu didn't sell Guan Zi and continued: "With the cultivation realm of Young Master Long and Elder Li, ordinary five-star powerhouses can't be completely sure of winning. However, we saw that there was no trace of a fight at the scene, which was a very abnormal phenomenon. So I boldly guess that there are two situations, one is that the opponent's cultivation is extremely advanced and can kill with one blow. Second, this is not the scene of the first crime, he was forged by the murderer. ”

The two results, the two situations, are not what Long Zhennan is willing to accept.

Seeing Long Zhennan's slightly lost look, Mr. Liu took out a black and white mink from his sleeve.

When Long Zhennan saw this little mink, he was surprised and said, "This ...... This is the Tai Chi Shen Mink?"

Tai Chi Shen Mink, one of the eight ancient strange beasts. Naturally sensitive to spiritual power, he can smell the remaining spiritual power fluctuations in the air. In nature, danger can be greatly avoided. At the same time, I am also interested in some treasures with aura and spiritual power. In general, the Tai Chi Shen Mink is used to explore the treasures of the ruins. Like Mr. Liu, he was the first person to use Tai Chi Shen Mink to investigate the scene of the murder.

Hearing Long Zhennan's question, Mr. Liu just smiled and said nothing. He held the black and white mink in his hand and stroked it lightly. Place the mink on top of the brown soil and let it walk.

The Tai Chi Shen Mink sniffed and walked, and when it smelled a piece of brown soil, its fur exploded. As if smelling something terrible, he curled up on the ground and stopped.

Mr. Liu took three steps and made two steps, ran to the side of the Taiji Shen Mink, and hurriedly picked up the little mink and stroked it. After a while, the Tai Chi Shen Mink returned to normal. Mr. Liu took out a small red flag and inserted it in the place where the Tai Chi God Mink had just exploded. Then he put the Tai Chi Shen Mink on the ground and let it swim away.

Without two steps, the Tai Chi Shen Mink fried its fur again. The same appeasement, planting the flag.

Mr. Liu felt that this area was a little weird, and the concentration of energy was a little beyond common sense. Instead of putting the mink on the ground, he held the mink in his arms all the time. Every time I walk through a place, I will let the mink sniff it, and once I find the mink fried hair, I will plant a flag in that place, and then appease it.

This continued all afternoon, until the sun went down and all the flags were planted. Such a scene reminded Fang Ze of a game he played in his previous life, Minesweeper.

When Fang Ze saw the dense flags on the ground, he was stunned. Isn't this the location where the spirit thunder fell yesterday? I don't remember it very clearly, but the area is probably fine. Roughly counted, more than one hundred and forty flags.

And outside the whole red flag, there are two places, and the yellow flag is planted. Looking at the location, Fang Ze knew that these two places were the locations where the spiritual power karmic fire erupted when he cast the Spirit Shadow Step.

In his previous life, Fang Ze knew that the police were very powerful. Coming to this world, this investigation is also so good. When you see those flags, it's easy to think of what happened. However, such associations only exist in Fang Ze's mind, and it is difficult for outsiders to associate them. Because they don't know that there is such a thing as spiritual thunder in this world.

Brushing his beard, Mr. Liu's brows were twisted into a pimple. I have been investigating the case all my life, and I have never seen such a murder scene. How do you manage so many energy points, such a high concentration of energy?

Just as he was thinking, the Tai Chi Shen Mink was on the side, gnawing on a stone. Hearing the click, Mr. Liu looked at the mink. yelled: "You brute, why do you eat everything"

After speaking, he walked towards the Tai Chi Shen Mink and grabbed him by the neck. When I looked up, I found that the Tai Chi Shen Mink was eating an orange spirit crystal. Mr. Liu was relieved.

In order to ensure the spirituality of the Tai Chi Shen Mink, Mr. Liu will feed it with spirit crystals every day. As for other foods, Mr. Liu resolutely did not let the little mink eat them.

"There is a question", this is the answer that comes to Mr. Liu's mind.

I saw him pull the spirit crystal from Tai Chi Mink's mouth, and Tai Chi Mink's big watery eyes looked at Mr. Liu innocently. It means as if to say, "Don't take it, I'm hungry, I want to eat." ”

This scene was also seen by Fang Ze, and he couldn't help but think of his son Tianyan. I thought to myself, "I should still be good to my son, at least the spirit crystal can be supplied." ”

Mr. Liu put the Tai Chi Mink in his sleeve and walked somewhere, and then the judge's pen was waved. Ash was carried again, and a black patch of soil was exposed. At this time, above the soil, there are sparse orange and red spirit crystals. It's not much, but it's obvious.

Fang Ze really regretted his intestines, he accidentally fell while walking yesterday. Maybe it's also that the performance is too involved and forgets these details.

Mr. Liu picked up the spirit crystal on the ground, walked to Long Zhennan's side and said, "Old helmsman, things are clear. The two of them set up a formation here and lured Childe into the formation. Do you see the two places where the yellow flags were planted? It should be the trajectory of one of them fleeing when the formation was activated. ”

Long Zhennan looked at the red flag area, and then looked at the two yellow flags on the ground, and also agreed with Mr. Liu's statement. Then he asked: "May I ask Mr. Liu, do you have an eyebrow about the identity of the murderer?"

Mr. Liu was a little embarrassed, and said hesitantly: "Well, this...... I need to go back and look up some more information to see where this formation comes from. Moreover, the evidence is incomplete now, and we have to wait for other evidence to corroborate it. ”

"How long will it take to find out?" asked Long Zhennan angrily.

Mr. Liu thought for a while and said, "It will take five to ten days to determine the specific information of the murderer." ”

Long Zhennan was a little unhappy, and at the beginning he invited Mr. Liu to come, hoping that Mr. Liu would immediately find out who the murderer was? But what he didn't expect was that after a busy afternoon, he knew that the murderer was two people, one tall and one short. The anger in Long Zhennan's heart has nowhere to vent, how can he have any good temper.

After Mr. Liu marked the position of the flag on the scene, he put the spirit crystals scattered on the ground into a cloth bag. Long Zhennan ordered the ashes and brown dirt on the ground to be loaded into the prepared coffin. In his eyes, these were the remains of his son.

Everyone carried the coffin and returned to the Dragon Shark Gang.

Seeing such a fruitless investigation, the onlookers also broke up unhappily.

Fang Ze followed the retreating crowd and gradually disappeared into the flow of people.

Back in the woods, where the two of them rested last night. Without waiting for Fang Ze to speak, Song Huan opened his mouth first and asked, "How is it?"

Fang Ze pretended to be frustrated, and sat on the ground silently.

Song Huan was anxious and continued to ask: "Are you talking, have you found out?"

Fang Ze still didn't speak, just looked at Song Huan's anxious look.

Song Huan took Fang Ze's arm and said directly: "Go, hurry up, let's run away." Go back to the academy and pack up, let's find a place to hide. ”

"Poof", Fang Ze laughed. said: "Haha, I've never seen you in such a hurry." Look at what scares you, you're really laughing at me. ”

Song Huan was angry and laughed when he saw Fang Ze like this, and continued to ask, "Did you find out?"

Fang Ze patted the land next to him and motioned for Song Huan to sit down. Then he said: "I didn't find out, but it's fast." ”

Song Huan continued to ask: "Then what should we do next, is it to go back, or how?"

Fang Ze looked at the sky in the distance and said, "Tomorrow we will steal something."

"Steal something, steal something, what's your idea?" Song Huan asked eagerly.

Fang Ze was silent, just replied simply, "You'll know tomorrow." ”
