Yang Chengye crouched down to examine the two corpses, one of which was indeed Zhao Si's. His brow was furrowed, his lips were purple, and a tip of his tongue protruded from his mouth, but he had not suffered before death.

  Another was a woman, with a slightly bulging abdomen, an ordinary face, and wide-open eyes, apparently frightened before death, with her tongue also sticking out of her mouth.

  Yang Chengye reached out his hand to lift Zhao Si's chin for a look.

  "Where did this little kid come from? What a nuisance! Get out of here quickly!"

  At this time, the executioner suddenly lifted his head and shouted at Yang Chengye.

  Yang Chengye, as a new youth of the 21st century, majored in forensic medicine in college. After graduation, he entered the public security department and became a forensic doctor. He has done countless autopsies.

  Hearing the clamor of the servants, Wang An hastened his steps and asked: "What has happened?"

  The coroner pointed at Yang Chengye and cupped his hands, saying: "Sir, I'm in the middle of examining the body. Who knows where this kid came from? He's actually touching the body! What if he damages it?"

  Wang An glanced at Yang Chengye and showed a hint of disdain. He asked the coroner, "How's the autopsy?"

  "Welcome back, sir!"

  The coroner replied, "Indeed, both corpses died by their own hands, but as for why they hanged themselves, that's unknown."

  Upon hearing this, Wang An nodded and said: "Since that's the case, let's have Zhao Daizhi and his wife carried away and given a proper burial."

  "Wait!"

  Yang Chengye suddenly spoke up and said: "Sir, the body has not been examined clearly, and it's a bit hasty to bury it like this, isn't it?"

  After hearing Yang Chengye's words, Wang An angrily said: "Yang Gongzi, this official is tolerating you because the imperial envoy allowed you to investigate the case of disaster relief grain. Don't take advantage of it!"

  Yang Chengye stared at Wang An and said, "Sir, I feel that Zhao's death has other hidden circumstances, and he is a key figure in the case of disaster relief grain. Therefore, I have an obligation to stop his burial."

  "Nonsense!"

  Without waiting for Wang An to speak, the coroner cut in and said: "I've already examined Zhao's body, could my judgment be wrong?"

  "I am following the book written by Song Ci, a great official of the Song Dynasty, how can I be wrong?"

  "How dare you question Mr. Song?"

  Yang Chengye did not expect this coffin to actually lift out Song Ci.

  As for Song Ci, Yang Chengye still has some understanding of him. Song Ci was indeed the Judicial Commissioner of Southern Song Dynasty, who had judged countless cases and never had any miscarriage of justice.

  Song Ci was an outstanding forensic medical scientist in ancient China, known as the "Father of Forensic Medicine". The book he wrote, "Washing Away Wrongful Deaths", is the world's first forensic medicine monograph.

  Song Ci successively held four senior judicial positions and later served as a messenger in the Zhi Bao Ge, spending his life dealing with justice and punishment.

  Song Ci's long-term professional work accumulated rich experience in forensic examination, and his later work "Wash Wrong Collection" is a milestone in Chinese and even world forensic medicine.

  Yang Chengye's specialty is forensic medicine. As for "Washing Away Wrongful Deaths", he can recite it fluently and apply it flexibly in practice.

  At this time, Yang Chengye was also ignited with anger and coldly said to the servant: "The book written by Mr. Song is certainly not wrong, but you have misinterpreted Mr. Song's meaning."

  "I've come to ask you, what would it be like for a person to hang themselves?"

  "Hmmph!"

  He snorted coldly and said, "In the 'Washing Unjust Cases' collection, there is a sentence in the autopsy description of hanging oneself. If it's really self-hanging, then three feet below where the feet are tied should be dug up to find charcoal."

  "We did indeed dig up charcoal from under the ground where Zhao's head was hung. Doesn't this prove that they died by their own hands?"

  Yang Chengye arrived at the place where Zhao Si hanged himself and indeed saw a pit on the ground with several pieces of charcoal inside, but this charcoal was man-made.

  Yang Chengye then lifted Zhao Si's chin and saw that there were two marks on his neck, one slightly deeper and dark purple in color, the other shallower and white.

  Yang Chengye looked at the coroner and said in a low voice: "The Zhao couple did not commit suicide, but were murdered by him."

  Upon hearing this, Wu Zuo's eyes widened instantly, and he looked at Yang Chengye with a ferocious expression.

  "Wang An asked: 'Did Young Master Yang see anything?'"

  Yang Chengye pointed to the pile of charcoal and said, "These charcoals were not formed naturally, but were buried by the murderer after killing Zhao's husband and wife. Naturally formed charcoals would not be so disordered. The murderer is very familiar with 'Washing the Unjust'."

  Yang Chengye then pointed at Zhao Si's wife and said: "Also, the wife of Police Officer Zhao has dilated pupils, obviously she was frightened before her death."

  "The most crucial is Zhao Tou, his eyes are tightly closed and he didn't endure any pain, obviously he was very familiar with the murderer. He didn't expect the murderer to suddenly attack him. You all come see."

  Yang Chengye said as he reached out and lifted up Zhao's husband and wife's chin.

  "Zhao the captain and his wife both had two marks on their necks, one deep purple and one white. The white mark was left by hanging themselves from a beam, but it was actually the deep purple mark that was fatal."

  "It can thus be concluded that they were strangled first and then hung from the beam, creating a false impression of suicide by hanging."

  "How is this possible? Could it be that Lord Song's records were incorrect?" Yu Zuo exclaimed in surprise.

  Yang Chengye glanced at him and said: "What Mr. Song recorded was not wrong, but you shouldn't apply it rigidly, each case has its own particularities."

  At this time, Wang An asked: "Do you know who is the murderer?"

  Yang Chengye shook his head and said, "I don't know!"

  Wang An angrily said: "This person is really devoid of conscience, Zhao's wife is already pregnant, and yet he can still commit such a heinous crime. The government will definitely find the murderer and execute him by slow slicing!"

  Yang Chengye pinched each of the two corpses again and looked at Wang An's back as he walked away.

  Zhao Butou was a key figure in the disaster relief grain case and is now dead, it seems that the opponent has discovered it, and it should be murder to silence.

  Suddenly, Yang Chengye thought of something and quickly left Zhao Si's home. Since Zhao Si was already dead, that meant another person in the case was also in danger.

  Yang Chengye arrived at the teacher's home according to what he knew.

  His name was Zhou Tai, a Shaoxing native who had served three magistrates in Jiaxing Prefecture.

  When Yang Chengye arrived at Zhou Tai's house, he indeed heard the sound of dogs barking and chickens flying.

  Yang Chengye hastily pushed open the gate and saw that the whole yard was in a mess, with fragments of pots and pans scattered all over the place, and even bedding and household items were thrown into the yard.

  "Oh no, don't!"

  Suddenly, Yang Chengye heard a terrified cry coming from inside the room and rushed in hastily. When he saw the situation inside the room, his eyes suddenly narrowed.

  All that could be seen was clutter everywhere in the room, Zhou Tai was disheveled and unkempt, shrinking into a corner of the wall.

  "Don't kill me, don't kill me..."

  Zhou Tai muttered repeatedly in his mouth.

  "Master, I'm Yang Chengye, and I didn't come here to kill you!"

  Yang Chengye tried to get close to Zhou Tai, but unexpectedly, Zhou Tai picked up the nearby objects and threw them over, while continuing to back away, shouting in terror: "Don't kill me, don't kill me......"
