Yan Langzhong's opinion was quickly supported by the court officials of the Criminal Department, who ordered him to review the case. After Yan Langzhong received the order, he retrieved the physical evidence that existed in the Jiangning County Ya to confirm the previous speculation.

Because of the hot weather in June, the body could not be parked in the coroner's room for too long, and the deceased had already been buried, and there would be great resistance to opening the coffin for an autopsy. If there is a real culprit, it will also cause alarm. Yan Langzhong had no choice but to retreat, first observing the rubbing that he had made from the wound of the deceased, and found that it was indeed caused by the penetration of a sharp blade, not by a sickle.

And on the sickle, which was designated as the murder weapon, there were only pale green sink traces, and there was no trace of blood. Judging from the conclusion of the preliminary trial, Qi Dazhu should have fled immediately after the killing, and there was no time to clean the murder weapon, such a big loophole could be ignored by Jiangning Zhixian, Yan Langzhong was simply speechless.

There is also the bloody clothes, although it has been soaked in water, it can still be clearly seen that the blood stains are mainly on the bottom of the sleeves and placket, but the large placket is clean, and judging from the shape and position of the deceased's wound, the murderer stabbed it head-on with a sharp knife, and the blood will be sprayed and splashed on the murderer's placket, and the sleeves and hem are unlikely to be stained with blood. On the contrary, as Naqi Dazhu confessed before, saying that after he tripped over the corpse because it was dark, he groped and found the deceased before he was scared away, which is more in line with the evidence. What's more, the deceased and Qi Dazhu didn't know each other, and the most basic motive for killing didn't exist, so how could he suddenly commit such a murderous attack?

With these observations, he determined that the murder weapon and bloody clothes and boots were not enough evidence, so it was likely that Jiangning Zhixian had cast an unjust case. In order to find out the truth, he did not immediately open a court to ask about the case, but visited the neighbors of Waterwheel Lane. Through knocking on the deceased's neighborhood, he learned that Zhang Ma was a hard-working man, and after being widowed in his twenties, he worked hard to pull his only son Zhang Gouzi up, and he thought that he could finally breathe a sigh of relief, but who knew that the son was not angry, and he was idle all day long, not doing his job, and often stealing the two coffin books that Zhang Ma had worked so hard to save. For this reason, the mother and son turned against each other, quarreled a lot, and she was even beaten by the rebel.

Yan Langzhong carefully visited the neighbors of the Zhang family, and finally came up with a key piece of information - in the middle of the night on the day Zhang Ma was killed, he had a fierce quarrel with Zhang Gouzi, which woke up the neighbors. However, everyone was afraid of Zhang Gouzi, the murderer, and they didn't dare to come out to persuade him, and then they heard that the voice was gone, thinking that the two of them had finished arguing and fell asleep, but who knew that Zhang's mother was killed the next day...... Yan Langzhong asked about the content of the quarrel again, but the neighbors didn't listen to it, as if 'you can't take it', 'you let go' or something like that......

"Zhang Ma's son is called Zhang Gouzi?" Seeing this, Wang Xian was suddenly stunned, "This name is familiar." ”

"One of the three people who ate the rod yesterday is called that." Wu Weidao.

"It's kind of interesting...... Wang Xian touched his chin and muttered, continuing to read:

Zhang Gouzi was a secret agent of Beizhen Fusi at that time. The reason why Jinyiwei can monitor the world, especially the wind and grass in the capital, cannot escape their ears and eyes, the key is the ubiquitous secret agents. Especially those idle and well-informed scoundrels and idlers basically hook up with Jinyiwei, and sell the news in exchange for some wine money and prostitution.

These spies are not Jinyiwei's people, they are just Jinyiwei's dogs. But Zhang Gouzi created a miracle, he actually became an official brocade guard, and he became an officer at once...... Although it is a small flag that only manages ten people, this is still more surprising than Wang Xian suddenly becoming the Fusi of Beizhen.

This earth-shaking change happened to happen shortly after Zhang's mother was killed, and what happened during this period not only made Wang Xian, a conspiracy theorist, curious, but also attracted Yan Langzhong's attention. Yan Langzhong has been in the criminal department for more than ten years, and he also has his own 'secret pile', he paid for people to investigate, and the reason for Zhang Gouzi's sudden outbreak. He knew that it was not difficult to investigate, because those secret agents and the ordinary wrestlers and captains of Jinyiwei were all pressed down by Zhang Gouzi at once, and there must be someone who is not angry, and they will talk about it without asking.

Sure enough, the results were not long in coming...... It turned out that Zhang Gouzi gave a family heirloom to Li Chun, the deputy town of Beizhen Fusi, and with Li Chun's power, he wanted to make Zhang Gouzi a formal brocade guard, and then give him a petty official, which was naturally easy. is worthy of the brocade guards who specialize in finding out the news, and some people even found out what the heirloom is...... It is said to be a jasper watermelon that flowed out of the imperial palace of the Yuan Dynasty. It is said that Zhang Gouzi's grandmother once worked as a female official in the palace of the Yuan Dynasty, and she stole it out when the war was in chaos.

Yan Langzhong asked the neighbors of the Zhang family for verification, and the neighbors had not heard of any jasper watermelons, but confirmed that Zhang Gouzi's grandmother was indeed from the Yuan Dynasty Palace.

In this way, Lieutenant Yan Lang regarded Zhang Gouzi as the number one suspect, but it had been more than a month since the case, and Zhang Gouzi was a Jinyiwei with strong anti-reconnaissance capabilities, and he must have annihilated the evidence of the crime. However, Yan Langzhong, with his rich experience, did not take this difficulty seriously. He asked someone to find a standard short knife of the Jinyi Guard...... It is a smaller embroidered spring knife, which is specially used for secret agents to defend themselves. After comparison, it was found that the wound of the deceased was caused by this weapon!

Yan Langzhong quietly sent two capable catchers with excellent water ability, and ordered them to disguise themselves as swimmers to cool off, and went down to the lake a few steps away from the scene of the crime to look for them, and actually found a sharp knife in the aquatic plants not far from the shore. When I brought it back, it was the standard broken blade of Jinyiwei. And although it has been soaked in the water for many days, a faint trace of blood can still be found on the handle of the knife with thick wires entwined.

And there is a number on the knife handle, as long as you compare the distribution record of Jinyiwei, you can find the owner of the knife!

At this point, Yan Langzhong finally had the confidence to reiterate the case, and he suddenly ordered Zhang Gouzi to be summoned. Zhang Gouzi was already an officer of Jinyiwei, so he naturally didn't dare to take him, so he could only invite him over. At the beginning, Zhang Gouzi looked arrogant, and said impatiently, the case has been understood, why do you call this official to do it?

"How many questions do you have to ask for verification?" Yan Langzhong said quietly: "Where were you on the night of the crime?" ”

"As I said earlier, I'm out eating." Zhang Gouzi said.

"Where? And with whom? ”

"Qiu Ju's single room on the second floor of Yuyangju, and a few of my brothers." Zhang Gouzi said impatiently: "At that time, Yang Zhixian had already asked, and summoned my brother and the shopkeeper over, and the files were clearly written, and the adults would not read it themselves." After speaking, he was about to leave: "I have nothing else to do, I have to leave, I have delayed the imperial mission of this official, can you afford it?" ”

"You're lying!" Who knew that Yan Langzhong slapped the shocked wooden and said: "In Qiu Ju's private room that day, it was Chen Sijin, the head of the household department, who was drinking and talking with several people in the same year, and sat until it closed from dark to close!" ”

Zhang Gouzi was stunned for a moment, he didn't expect this Yan Langzhong **** to come to this point, but he was not slow to react, and pretended to be flat: "Maybe the surname Chen is wrong." ”

"Could it be that several officials are mistaken?" Yan Langzhong sneered: "They are all young two-rank jinshi, and each of them has written conclusive testimony!" Whose words are more credible for you! ”

"That's what we remembered...... "Master Jinshi, those are all Wenqu stars, Yan Langzhong shouted like this, and Zhang Gouzi showed his timidity.

"Then why isn't your testimony written in black and white, plus the five people in the store, they all say that it is in Qiu Ju!" Yan Langzhong said and patted the case heavily: "Jia Liuzi's wife had a difficult birth that afternoon, and he didn't give birth until midnight, and he still has the time to accompany you out to drink, so he's really calm!" That night, Zhou Lao Wu lost all his money in the casino and had a fight, which was recorded in the patrol room. That night, the red monkey was a prostitute in Chunxiang Building, and he paid the prostitution fee but came out to drink with you? And Ji Datou should have been on an errand in the edict prison that day, and he also ran out to eat with you? ”

Yan Langzhong was armed with a gun and a stick based on strict evidence, which made Zhang Gouzi speechless, and said angrily: "You don't care where I do!" Could it be that I killed my mother? ”

"It's not impossible to kill your mother and seize the treasure." Yan Langzhong said calmly: "Where is your jasper watermelon?" "Fiction and reality are king, just now he spat a nail, which deeply shocked Zhang Gouzi, and then threw out this kind of speculation, only then did it have a shocking effect.

Sure enough, a burst of panic flashed on Zhang Gouzi's face, and he hurriedly covered it up: "What jasper watermelon, why don't I know it!" ”

"Without jasper watermelon, why did you go from an unidentified spy to a Jinyi guard officer from the seventh grade?" Yan Langzhong patted the case and said: "What kind of merit have you made to achieve the super-promotion from the people to the official and the promotion of seven levels in a row?!" ”

"This ......" Zhang Gouzi was speechless.

"Where is the short blade that Jin Yiwei issued to you?" Yan Langzhong is not entangled, the truth is the truth.

"I'm not a secret agent now, so I'll naturally hand it over......" Zhang Gouzi saw sweat on his forehead, and he couldn't get up.

"Are you sure?"

"Sure."

"What's the number on the hilt!" Yan Langzhong didn't give him time to think at all, and asked jumping questions one after another.

"Geng Si'er......" Zhang Gouzi blurted out, and his face changed after speaking.

"Look what this is!" Yan Langzhong nodded, and an errand came up with a tray, on which lay a narrow short knife, and the words 'Geng 42' were engraved on the copper handle!

"This was fished from the lake a few steps away from the scene of the crime!" Yan Langzhong's eyes were cold and said, "And the wound on your mother's body is completely consistent with this knife!" How do you explain that? ”

"......" Zhang Gouzi's heart defense completely collapsed, but he relied on it in his heart, and he refused to make a sound. Seeing that he just didn't admit it, Yan Langzhong had no choice, Zhang Gouzi was now an officer of Jinyiwei, and he couldn't be tortured before he took off his official clothes. If you can't handle this case today, you will have a lot of dreams in the coming days.
