The next day, Xiao Qianqin came to see Tang Yun and told him an important clue.

It turned out that after Xiao Qianqin returned to the palace yesterday, she was busy handling some pieces of music and handing over some important affairs to the empress to make decisions.

Ruoshui, who went out to look for clues, had returned, and they checked all the records of entering and leaving the palace at that time, and after investigation, they found that on the day of the autumn festival, there was a charcoal cart from the palace that passed in front of the imperial gate.

The weather has gradually turned colder, especially in the season of Shendu, where the leaves are falling everywhere and the cold wind is gusting, so the amount of charcoal needed is also more.

Because the charcoal trucks were often dirty, and the appearance was already pitch black, and it was a little late at that time, the prison guards did not care, and after checking it, they let them go.

At that time, it was already late at night, and the person pulling the cart kept urging, saying that if it was too late, the imperial city gate would be closed, and he would not be able to get out.

At this moment, suddenly Yin Cui Houen of the Shendu Mansion knocked on the palace door and said that there was something important to report.

The palace gate usually does not open at night, and the guard sergeant guarding the city hangs down a bamboo basket and lets Cui Houen step on the bamboo basket to go to the imperial city.

Xiao Qianqin, who Cui Houen went to see first, because she was the commander of Ruoshui, and assisted in searching for the whereabouts of Princess Jinyang, Xiao Qianqin also sent an order to Cui Houen.

Just now, Choi said, his men spotted a coal truck that had fallen into the river by the river.

The car was supposed to sink to the bottom of the river, but who knew that one of the wheels got stuck in a stone slab, causing the whole car to be embedded in the stone slab and unable to move, but it still did not sink to the bottom of the river.

Xiao Qianqin was in the palace at the time, and she was not allowed to go out without a will. So he asked Cui Fatzi to send someone to protect the scene.

Xiao Qianqin said: "I suspect that the carriage that transported charcoal is very likely to hide Her Royal Highness the princess inside." So I came to you early this morning, thinking that if you could help, it would save you a lot of effort. ”

Tang Yun smiled, hesitated slightly, and still told Xiao Qianqin what he encountered yesterday.

Xiao Qianqin's face changed, and she muttered, "I heard Master Xia say that something happened to the Demon Suppression Tower. Now all the horsemen are gathered there, and even we Ruoshui don't know what's going on. ”

Tang Yun nodded: "It's important to find the Duke of Jinyang first, and let Master Xia worry about the matter of the Demon Suppression Tower." ”

Together, the two went to the location that Choi Hou-eun had said, and the place where the incident happened was on a small river between Thanh Hoa Fang and Le Tak Fang.

There are usually some boats ferrying here, but now all of them are blocked, and a group of officials from the Shendu Prefecture patrol the river back and forth with simple knives.

Yin Cui Houen of Shendu Mansion arrived here early in the morning, and when he saw Tang Yun's eyes lit up, he hurriedly greeted him and said, "Wait for the edict, Brother Tang, you came just in time, we found a corpse here." ”

Tang Yun glanced at it and saw a black carriage stuck by the river.

There are many stone terraces by the river, and some women will fetch water here to wash their clothes on weekdays. The wheels of the carriage happened to be stuck on the stone platform, and most of it had already submerged in the water, leaving only one carriage exposed.

On the shore, there was a carcass of a horse and a carcass of a person. The servants were busy around the corpses, and a group of servants were gathering around the side of the carriage, trying to push the carriage up.

Xiao Qianqin glanced at the shore from afar, and suddenly found that many people were watching from afar, whispering.

Xiao Qianqin frowned and scolded Cui Houen: "Didn't you keep a low profile." ”

Cui Houen's face drooped suddenly: "Xiao Zhizhao, this is not a matter of the lower officials." Now that Princess Jinyang has disappeared, the city has been full of turmoil, who doesn't know. This news can't be stopped, and even the officials under my command are secretly discussing it when they are idle. ”

Tang Yun had already walked to the corpse, and the person had already been soaked. After asking about his opinion, he said that this person was a groom who carried charcoal, and he had already made it clear that he was a eunuch. He must have been stabbed in the neck, and so was his horse, and the whole wagon was thrown into the river.

Unfortunately, the man who did this seemed to have done so and hurried away, not noticing that the carriage had not sunk into the river.

Tang Yun carefully examined the corpse, Xiao Qianqin walked over and asked in a low voice, "Did you find anything?" ”

Tang Yun's brows were always furrowed, he told Xiao Qianqin what he had just said, and then asked her, "Don't you think it's a little strange, this carriage can't sink to the bottom of the water at all." ”

Xiao Qianqin glanced at the surrounding scene, and suddenly realized: "Yes, the carriage is completely wooden, and the river is so shallow, even if the carriage is completely immersed in water, it is impossible to completely cover it." Could it be that someone did this on purpose? ”

Tang Yun noticed a servant standing in the distance, a little ready to speak, so he beckoned to him.

The work can only belong to the small officials, perhaps estimating the identities of Xiao Qianqin and Tang Yun, I am afraid that I will disturb the conversation of the big people in the past. Seeing Tang Yun waving, he hurriedly walked over.

"Two adults, I just found a murder weapon not far away, and there are some blood-stained strips of cloth on it. Small speculation, this should be left after the murderer killed. ”

He had a strange knife in his hand.

This knife looks very sharp, the whole knife is slender, the front is sharp but the back is a little curved, the handle is very short, and it is wrapped in cloth.

Tang Yun untied the cloth on the handle of the knife, and suddenly revealed a row of words, as if it had been blurred with a file.

Ordinary people rarely deliberately make the word with a knife wound, some old knives may be smoothed out, but the handle of the knife looks very bright, obviously usually wrapped with a cloth, very well protected.

These words may explain the origin of the knife.

Tang Yun carefully identified it, and he recognized that there were about six words engraved on this knife, but they had all been smoothed out, and he couldn't see what the words were.

"This should be the breakthrough." Tang Yun held the knife in his hand and looked back and forth.

The structure of this knife is completely different from the current Da Zhou horizontal knife, and the handle of today's knife is as long as possible in order to make the knife more secure.

This knife was somewhat like the riding knife used on horses, but the handle was shorter, and Tang Yun could be sure that he had never seen such a knife in the army.

Tang Yun swung it a few times, and the knife was unexpectedly very sharp, leaving a whirring sound in the air that pierced the air.

Xiao Qianqin smiled bitterly: "I finally got a clue, but it was interrupted here." ”

The two were at a loss, and at this moment, Cui Houen, who was looking at the knife on the side, suddenly spoke: "If it's just a knife, I may know one person, and he can know the origin of this knife." ”
