Li Canghai nodded, and then let him leave the Songhe Tower and go to open a warehouse to release grain to help the victims.

After Zuo Hongji left, Zhu Wen and the housekeeper were left at the scene.

Several people knelt on the ground, cold sweat was dripping from their foreheads, and they didn't even dare to breathe.

"Zhu Wen, as a servant, but you aided the torture and poisoned the prisoner, this is a capital crime!" Li Canghai raised his eyebrows and shouted.

Zhu Wen trembled with fright, he lowered his head and did not speak.

"However, for the sake of you confessing the murderer behind the scenes in time and turning into a tainted witness, this official will be dismissed from your position as a servant, never hired, and will be given another ten years of hard labor to compensate for your crimes." Li Canghai said lightly.

Zhu Wen was stunned, he didn't expect that he would still be alive, and immediately cried: "Thank you for your kindness, thank you for your kindness!" The little ones must reform themselves in the future and be a good man! ”

After sentencing Zhu Wen, Li Canghai glanced at Wang Buquan's housekeeper.

The housekeeper trembled and knelt on the ground, and when he saw Li Canghai glaring at him, he almost collapsed in fright.

Li Canghai turned to Chang Feng and asked, "Chang Feng, how many of Wang Buquan's minions have been captured this time?" ”

"Lord Hui, there are about 100 people, and now they are all locked in the broken temple in Xicheng." Chang Feng paused, and said adoringly: "My lord, you are really clever, let's put the drug in the wine, otherwise how can we catch Wang Buquan so many minions so easily?" ”

Li Canghai smiled indifferently: "Don't make a fool of yourself, this is all the credit of Zhang's life, if it weren't for his drug, you could only work hard." ”

"What my lord said is, Dr. Zhang, thank you so much this time." Chang Feng respectfully saluted Zhang Xuanming with his fists.

Zhang Hangming blew off his slender bangs and said with a smile: "The effort of the hand is not enough to worry about the teeth." ”

Li Canghai looked at Zhang Xuan, he found that this You Fang Langzhong was indeed not simple, he laughed lightly, he pointed to the housekeeper, and said in a deep voice: "Chang Feng, take this person and those minions to the Yellow River embankment, and let them build a dam to block the flood." ”

Chang Feng bowed down, then walked in front of the butler and dragged the soft butler out.

After the verdict was made, Li Canghai wrote a letter and sent it to Kang Xu quickly, asking him to return to Zhengyang City with the refugees.

Zhang Xuanming looked at Li Canghai and said with sincere admiration: "I, Zhang Xuanming, have traveled all over the world, and I can be regarded as well-informed, but I have never seen a character like an adult, in just two days, three murder cases have been solved, including two old cases." The ability of adults, I am afraid that today's Dali Temple may not be able to reach it! ”

Li Canghai smiled modestly and said: "Brother Zhang has won the award, as the saying goes, the way of heaven is clear, and the retribution is not happy, if it weren't for the fact that the king didn't do a lot of evil, how could I find out these many flaws?" In the end, I just borrowed the luck of the Heavenly Dao. ”

"Victory is not arrogant, the popularity of the big man is extraordinary, and Zhang hangs his life to admire." Zhang Xuanming approved, and then asked curiously: "However, I don't know anything and want to ask the adults for advice." ”

"Oh, what's the matter?" Li Canghai asked.

"Lord Shicai used the 'dripping bone method' to identify the identity of the deceased, but the deceased has been dead for more than a few months, even if the adult finds the blood sand and melts into the water, the color should be very light, how can it be so bright?"

Zhang Hangsheng was a little puzzled, it seemed a little unlikely that the blood sand after a few months could dissolve so much blood water.

Li Canghai smiled incomprehensibly, he took his right hand out of his sleeve, and Zhang Hangsheng found that his right thumb was soaked in blood, and there was a wound on his thumb, and there was faint blood oozing, he was stunned for a while.

"Brother Zhang's observation is really meticulous, the so-called blood sand is just some coagulated cinnabar, and the blood in the bowl is actually my own blood." Li Canghai smiled.

Zhang Hangming looked at him with some incredulity, and exclaimed, "How can your blood seep into the bones?" This is not common sense! ”

Li Canghai knew that the common sense he was talking about was actually a conclusion based on ancient medicine, that is, only blood with blood relations can penetrate into the bone marrow.

This is one of the more accepted methods of identifying bones in ancient times, and is usually used in cases where bones are found.

They will find people who are related to the victim by blood, take blood and drip it into the bones, and use them to confirm the identity of the bones.

This situation is simple to say, but it is not very common to encounter it.

First of all, the victim must be a corpse.

Secondly, it is necessary to find out the suspected identity of the bones, and use their suspected identities to find immediate relatives who are related by blood, and then confirm the bones by the drip bone method.

When bones are found, they are often many years later, and this kind of unsolved case has few clues, and secondly, it consumes energy, and few people ask.

After a long time, it will naturally come to an end.

The probability of using the dripping bone method is naturally very rare.

The dripping bone method and the dripping blood method have always been regarded as the norm, and no one doubts their authenticity.

However, Li Canghai knew that this method was actually unreliable.

Ancient medicine was not as developed as it was in later generations, and it was natural that DNA identification technology would not be known.

When Li Canghai was a forensic doctor in his previous life, he had some understanding of this aspect, at least he knew that the accurate method of determining blood relationship could only be through DNA identification.

The dripping bone method seems reasonable, but in fact it has great flaws.

Whether the bones are buried in the earth or stored in the open air, the soft tissues attached to them will decay until they disappear and dissolve, leaving a pile of white bones.

Without the protection of the flesh, the surface of the bone will corrode and crispy, and many small crevices and cracks will appear. At this time, not to mention blood, even water and urine can also seep into it.

Zhang was stunned when he listened, what DNA identification, what genetic technology, he was confused when he listened, like listening to a book from heaven.

It took Li Canghai a while to explain the problem to Zhang.

After Zhang Xuanming understood, he was deeply admired: "I didn't expect that adults can't help but be proficient in solving cases, and have such an understanding of medical Tao. ”

Li Canghai waved his hand and said with a smile: "Brother Zhang praised it falsely, for the medical Tao, I am only a little superficial, in front of Brother Zhang, I am just an axe." ”

Zhang Xuanming shook his head, he respectfully bowed to Li Canghai, and said: "The adults are very knowledgeable, which is really admirable, and this salute is to thank the adults for their grace in teaching and solving doubts." ”

Li Canghai hurriedly helped him up and said, "Brother Zhang, I'm scared." I just saw through the flaws of the dripping bone method, how can I be worthy of the four words 'teaching karma and solving doubts', it really torments me! ”

He didn't know that this 'dripping bone method' was enshrined as a guideline, and no one ever doubted it, and he saw through the flaws in a few words, which overturned the method that had been circulating for hundreds of years.

In Zhang Xuanming's view, although this behavior had an impact on the ancient law, it gave him hope for innovation.
