The case file is written about Liu Cheng, the grandson of the King of Mountains and Seas, who was assassinated in the room when he was practicing calligraphy in the room, and no one found him dead on the spot, and Liu Cheng did not go to eat at dinner, and the next people found Liu Cheng's body.

Immediately, the king of mountains and seas learned of his grandson's death, and immediately became furious, and immediately searched the house, but unfortunately the murderer was not found, this king of mountains and seas was also a ruthless man, and ordered Liu Cheng's body to be placed there as it was, as long as there was a pretense to let them do the autopsy.

There are many rules in such high-ranking households, one of which is that the body of the deceased must not be insulted, and no one is allowed to touch it after they die, even if it is unjustly killed, and it is not allowed to examine the body.

But the King of Mountains and Seas was not like this, but he asked him to check the body, which shows the generosity of the King of Mountains and Seas, as well as the determination of the King of Mountains and Seas to find the murderer.

It's a pity that a lot of methods have been used, but the murderer has still not been found.

Then the emperor knew about it and ordered Jingzhao Mansion Yin to investigate the real culprit, and then Jingzhao Mansion Yin searched for talents to solve the case throughout the Great Yuan Dynasty, and finally Xifeng'er, Huainanzi, and Zhou An came.

The entire Great Yuan Dynasty is really big, in fact, there are many people who solve the case, but only the three of them came, mainly because the Great Yuan Dynasty is a country where force is supreme, and it doesn't pay much attention to the people who solve the case.

After reading the case file, Zhou An shook his head, there was no useful information, no hints, there was an autopsy report at the back of the case file, Liu Cheng was hit to the heart and died, judging from the wound, the sword used by the murderer was not an ordinary sword, but a long and narrow sword, judging from Liu Cheng's injuries, it was killed with one blow, Liu Cheng did not react at all, and was killed.

Liu Cheng is a martial artist at the level of enlightenment, and he has also cultivated the methods of the dark world, but he still kills without resistance, which shows that this murderer is very strong.

Closing the case file in his hand, Zhou An decided to go to the Shanhai Palace, to see if he could get useful information.

Huainanzi also made this request and asked to go.

In the end, the governor of Jingzhao Mansion agreed to Zhou An and Huainanzi's request, and asked the two officials to take Zhou An and Huainanzi to the Shanhai Palace.

Xifengzi also left Jingzhao Mansion, but he didn't go to Shanhai Wangfu, and he didn't know where he went.

Zhou An and Huainanzi came to the palace of the king of Shanhai, but the king of Shanhai did not see them and directly asked them to go to the place of his grandson's death.

Zhou An and Huainanzi came to Liu Cheng's room, Huainanzi checked Liu Cheng's body, and Zhou An turned around in the room, first Zhou An looked at the doors and windows, Zhou An saw that the doors and windows did not open traces, could it be a closed room murder case, because there were no other entrances and exits.

However, this is not the ancient world of the previous life, this world not only has martial artists, but also supernatural powers like the dark world method, and there are many abilities that can be entered without entering through windows and doors, such as Zhou An's stepping on the mountain.

Then Zhou An looked at the traces on the ground, and finally Zhou An saw a little dirt next to the corpse, which was very inconsistent with the surroundings, surrounded by brick floors, and cleaned very cleanly, it was obvious that this trace of soil was brought back from outside.

Of course, it is also possible that the servants in the Shanhai Mansion were brought in, or other people brought in, but after Liu Cheng died, this house was sealed, and only a few people could enter.

In addition, the King of Mountains and Seas said that it was not allowed to destroy the scene of the crime, so a little fresh dirt here is suspicious. Search

Zhou An transported his true qi, shot out from his fingers, and transformed it into a spoon the size of a small thumb, and used his true qi to the maximum extent at the level of the first layer of Zhou An's day after tomorrow, using an out-of-body attack.

Then a small box appeared in Zhou An's hand, scooped it into the small box with a spoon, and then put it in the storage compartment.

The reason why Zhou An did this was because Zhou An and Huainanzi were in a competitive relationship, after all, whoever could catch the murderer would get a conscription order, and Zhou An would not tell him if he knew that Huainanzi and Xifengzi had received useful clues.

After Zhou An found that bit of soil, he looked for useful traces in the house, but Zhou An's luck seemed to have run out, and he didn't find any more useful clues.

Then Zhou An looked at Liu Cheng's body, and now Liu Cheng's body was leaning on the chair.

Zhou An walked towards Liu Cheng's body, and now Huainanzi was holding a small wooden clip, which was holding a trace of meat on Liu Cheng's body, putting it on a piece of white paper, and then sprinkling some white powder on it, wrapping it up and putting it in the box.

Zhou An's arrival, Huainanzi did not conduct another autopsy, as if Zhou An came very well, and it happened that he had finished the corpse experience.

After Huainanzi finished experiencing the corpse, he took out a packet of blue powder from the box and sprinkled it on the ground and walls little by little, as well as the decorations of the room, all sprinkled with blue powder.

The whole house was filled with blue, but after a few seconds, the blue disappeared and returned to normal, as if the blue powder had not been spilled at all.

Huainanzi couldn't destroy the scene of the crime, and the King of Mountains and Seas confessed that no matter how he investigated, he couldn't destroy it, so he didn't dare to destroy it.

Although he did not destroy it, there was no abnormality in the room, which made Huainanzi very disappointed, the blue powder he sprinkled had a special effect, and it could detect people who had major killing intent to the deceased.

However, there is nothing unusual, which means that the murderer deliberately avoided the methods he used, so it is possible that the murderer has learned to cheat, or the murderer often kills people secretly and knows these precautions.

Although after sprinkling the blue powder, he didn't find any clues, but he found a lot of clues when he examined the body just now, but now that Zhou An is here, he is not easy to use, so he plans to talk about it after leaving the Shanhai Palace, and then Huainanzi said to Zhou An and left.

And Zhou An continued to look at Liu Cheng's corpse, Zhou An didn't know much about autopsy, but Zhou An had studied some Chinese medicine after all, so he could still use it to test the corpse.

Immediately, Zhou An investigated the body.

But soon Zhou An discovered a problem, that is, many clues were destroyed, and the destruction was very secretive, if it weren't for Zhou An's cooperation with traditional Chinese medicine through the spiritual power of the White Tiger through Heavenly Danger Killing Intent, Zhou An would not have found it.

Zhou An immediately knew who did it, it must be someone who had done the autopsy before, they didn't want to leave the clues, as long as they found the murderer, they wanted to get a reward.

Zhou An was a little angry, they all erased the clues, Zhou An relied on his limited knowledge of traditional Chinese medicine, and he couldn't find the useful clues at all, so Zhou An just looked for a while and stopped looking.
