After receiving the Prime Minister's Great Seal, Qinghou Su Wan immediately led the local officials out of the palace to kneel and greet him, saying: "The ministers and civil and military officials kneel to welcome the Prime Minister."

"Gentlemen, please get up," and then walked into the gate of the official office, entered the public hall and sat down at the desk, Su Wan and the officials sat aside. Cheng Bigan looked at Qinghou and said, "Qinghou, why don't you see the national teacher?"

Su Wan stepped forward and bowed, and said, "The national teacher is resting quietly, and it is inconvenient to see people."

Cheng Bigan called the guards and said, "Go and invite the national teacher over."

The guards on both sides walked out and invited Sun Bao, the national teacher, to the official court. Sun Bao, the national teacher, looked up at the Cheng Bigan in the hall, knelt down and said, "Prime Minister."

"Take down the traitor Gongsun Leopard." Cheng Bigan stood and pointed angrily at Gongsun Leopard, and the guard stepped forward and pressed Gongsun Leopard who was kneeling on the ground. Seeing this, Qinghou Su Wan was shocked at first and then puzzled, stepped forward to look at Cheng Bigan, and said: "Prime Minister, you are really puzzled by the fact that you have won the national teacher Benhou, and please show the Prime Minister."

"Su Wan, the king's appointment of the princes on your side shows that he is so important to you, and he appoints you to the shelter to manage the people of one side, but the people under your rule are starving all over the wilderness, and they don't understand the people's feelings and like to hunt, you can be guilty. The national teacher Gongsun Leopard is a treacherous and evil person, poisoned and killed the mother of a country, Jiang Hou, sucking the brains of living people, how can you tolerate such a disaster for the country and the people, take it down and put it on death row, and ask and behead it after the autumn. Qinghou Su Wan was confined and was not allowed to go out until the case was clarified. "Cheng Bigan used this to knock the mountain and shock the tiger, and caught the opponent off guard.

When Su Wan was taken down by the guards behind him, he shouted: "Bigan, you dare to touch me, I am Queen Su's own brother, Bigan, Bigan."

"Take it down to parade through the streets, so that this prince can have a good look at the people in the city."

After Su Wan and the national teacher Sun Bao were taken down by the guards, the disciple Shu Tong entered and said: "The people in the city led the way, and the place where Ren Bo was buried was found."

"Where?"

"On the outskirts of the city."

"Take me there."

The disciple Shu Dong led Cheng Bigan and several officials to the outskirts of Yuncheng, which was surrounded by many trees and high mountains, which was a good place to bury the corpse, that is, hidden and not easy to be discovered. There were many onlookers here, but none of them dared to dig it. The soil here is so loose that it looks like someone has dug it up and filled it in. Passers-by often smell when they walk through here, and there is often a blood-red liquid oozing out of the new soil filled here, flies hovering in the air, or falling on the oozing blood-red liquid, and there are often some strange insects wriggling in the loose soil, slowly crawling out, becoming more and more dense, which makes the spectators feel very mysterious. Bigan stood aside and was thinking, and after a while, he called an official and said, "Is there a Taoist priest near Yuncheng?"

"There is a Taoist priest in Fengshan, and the lower official will go to Fengshan to invite that Taoist priest down the mountain."

"Most of the mountain people are high-minded people, take me there." Before Bigan left, he ordered the guards to take turns to guard the scene of the burial to protect the burial site from being destroyed, and sent his disciple Shu Dong to lead troops to search the residence of the national teacher Gongsun Leopard. Fengshan is a collection of the majesty of Mount Tai, the wonder of the Yellow Mountain, and the danger of Mount Hua, known as the first strange mountain in the world. Bigan has been going all the way, and you can see the wonder of it. This mountain has always been a rare wonder in the world, the strange stones are all hanging in the air, all over the mountain to find no pinch of soil, ethereal endless rolling spring, or like a tiger and leopard squatting and angry, or like a light kite standing on the rapids, but to stay in this, why should people ask the ancient immortals. Climb along this step road, the mountain is like an egg, the high one is several zhang, the size is billions, and the stone pile is a miracle. There are countless strange stones in the mountain piled up, these mountain stones are like houses, the big ones are like small hills, look at the scenery of a touch, almost no gaps, such as birds and beasts, static and moving. Its stone is like a turtle, such as a fish, such as a rabbit, descendant stone, yuan gem, five-trick stone, camel stone, parrot stone, sword test stone, gossip stone and other forms are vivid. Overlooking from afar, looking closely, looking up, leaning down and changing endlessly, thousands of postures, the rock wall stone level plate road climbs, you will arrive at the Baiyun Wuhua Palace. They stood at the gate of Baiyun Wuhua Palace, and Cheng Bigan stepped forward and knocked on the mountain gate, and it was a shepherd boy who opened the door.

"Who are you, what are you looking for my master?"

"In Xia Nai Yin Shang Cheng Cheng is doing it, I am here to invite Master Guiguan to go down the mountain."

The shepherd boy brought Cheng Bigan in, entered the grass hall and sat down, and then walked into an old man: "Immeasurable Heavenly Venerable, I don't know who the two are......?"

Cheng Bigan stood up, and the official then said, "In Xia Bigan, this is Lord Yu, a junior minister."

"The prime minister's name and poor road have long heard of it, I don't know why the prime minister came to find the poor road?"

"There was a big case in Yuncheng, and I invited the master to go out of the mountain with me to help me solve the case, and I also asked the master to go out of the mountain to help, and I would be grateful to do it in Xiabi."

"The prime minister invites him, and the poor road is willing to go down the mountain with the prime minister."

The Taoist priest went down the mountain with Bigan and instructed the Taoist boy to watch the mountain gate and return soon. After going down the mountain, he rode into Yuncheng with Bigan and came to the scene of the crime. The Taoist priest walked out to observe the surrounding mountains, and the middle of the surrounding mountains is like a big basin, surrounded by many shades, many mountains blow in, the wind is chaotic so it is called the demon wind, and said: "This is an evil art, there is shade around it, the sun is difficult to shine into the yin land, and it is a good Gu pot, the wind in the mountains is disturbed by its demon wind, and when the moon is full, the yin of heaven and earth will be collected, and the people behind the scenes will use this corpse control technique for the evil world, this is the legendary resurrection of the corpse but there is a difference." If you look at the soil again, there is blood seeping out, the blood comes out of the soil, the corpses buried in the ground are stiff and not rotten, and there is a foul smell coming out, causing the Gu worms to break through the skin and turn into pus, then it is terrible. Then the Taoist priest sprinkled phosphorus on the soil, lit a fire, and the blue flame burned, luring out the Gu worms in the soil, and they were burned to death by the phosphorus fire. Then the Taoist priest turned to them behind him and said, "You can break ground." And in the southeast corner, he inserted incense wax, burned some paper money, and sprinkled apricot yellow paper on the mound. Only then did the officers and soldiers step forward and begin to break ground, and some rags were dug out, and the corpses were dug deep and lay in the dug pit. The coroner came, and the coroner entered to begin the autopsy, saying, "The skin of the corpse is intact, and there are no fatal wounds." A silver needle was inserted into the abdomen and removed to appear jet black, indicating signs of poisoning. When the corpse was turned over, it was found that there were two holes in the back of the head, and a small amount of blood was oozing from the back of the head, as if it had been pierced by some ferocious animal with fangs, and there were traces of teeth. Then the coroner stepped forward and said, "The deceased was poisoned to death first, and then a fierce beast pierced his fangs to suck the brain marrow." Disciple Shu Tong led the officers and soldiers to rush into the residence of the national teacher Gongsun Leopard, searched everywhere, and found the mask of the evil ghost under the pillow, the blue-faced fangs, the fangs are inlaid with bronze, sharp as a knife blade, the blood stains on the fangs are clearly visible, some suspicious, returned to the scene with the mask of the evil ghost, and said: "Sir, we searched all over the residence of the national teacher Gongsun Leopard, and found nothing, only this evil ghost mask is a little suspicious." Bigan took the demon mask, compared his fangs with the wound of the deceased, completely matched, and said to the notekeeper beside him: "Remember, there is no fatal wound around the skin of the deceased, only the wound on the back of the head is completely consistent with the murder weapon, and the deceased was poisoned by someone and then used the murder weapon to bite into the back of the head." The chronicler around him recorded this as the only evidence that Gongsun Leopard killed the imperial court official. The Taoist priest stepped forward and said, "The corpse must be burned before dark, otherwise disaster will occur." The corpse was placed on dry firewood, and the black smoke billowed from the fire, and the body was reduced to ashes, only the bones scattered in the firewood fire. returned to the official residence where Uncle Ren lived, entered the room where Uncle Ren had an accident, and asked the disciple Shu Dong beside him, "Shu Dong, let me analyze, how did the murderer poison and quietly enter the deceased's room?"

Shu Tong first looked at the desk behind him, stepped forward and sat down to ponder, then got up and stood in front of the window, opened the window, looked at the window sill, turned to face everyone, and said: "I think the case developed like this, the murderer entered the pantry and poisoned the tea that the deceased drank, and then entered the deceased's study in a grand manner, because the murderer is the object of the deceased's investigation, and acquaintances do not need to jump out of the window to commit the crime."

Bigan stood in the middle of them and said: "If the deceased had been poisoned before returning to the residence, and the murderer had already determined the time of his death and came to visit and investigate, we know that the deceased felt dry mouth after returning to the mansion and told the old servant to go into the pantry and pour some tea, then the question arises, when did the murderer sneak into the deceased's room and commit the murder?" Could it be the short time when the old servant entered the pantry? After finishing speaking, he looked at the officials around him, these officials also didn't know why, and Shu Dong was also ignorant. Then Bigan asked the officials next to him and said, "The old servant was locked up in that prison at the time, take me there quickly."

"The prime minister is coming with us." Cheng Bigan and several officials walked out of the official residence where Ren Bo lived, walked towards the government office, and walked towards the cell. The jailer stepped forward and opened the cell. After entering, he turned to face them and said, "The old servant committed suicide in fear of sin in this cell."

Then the officials nodded and said, "Yes."

"Tell me about the details of the old servant's suicide in fear of sin."

An official called a jailer, who stood in front of Cheng Bigan and recalled: "The old servant was locked in the night before, and on this night the national teacher came to visit the prison and ordered all of us to go out, which was very mysterious, leaving only the old servant and the national teacher in the cell, and after the national teacher left, the old servant was like crazy, and none of us could stop him, and he crashed against the wall and died." Cheng Bigan looked at the wall behind him, there were indeed blood stains on the wall, and it seemed that what the jailer said was true. Suddenly turned to face the official behind him and said, "Where is the body of the old servant?"

These officials all drooped their heads, and for a long time they came up with a sentence: "Burned."

"You are so bold," the officials knelt on the ground and said, "The officials are guilty, please forgive the prime minister."

Cheng Bigan accused them: "You don't investigate the cause of death of the deceased, so hastily dispose of the body, is this how you handle the case?"

"It was the marquis of Qing who ordered the lower officials to do this, and the lower officials didn't dare to check if they wanted to!"

"Okay, wait until this case is concluded, and then come to settle the stolen money you embezzled, you must cooperate with the official to investigate the case, and if you conceal it, you will be punished for several crimes."

"The lower officials must know everything and say everything."

"All right, get up."

When he returned to his official residence, a servant entered and said, "Master, I am waiting outside the gate of the house to be summoned alone."

Cheng Bigan raised his head and looked at this person, and said, "Have you ever asked him who he is?"

"I asked, and he said that he was Master Ren's entourage."

"Call him in, the old man is waiting for him in the hall."

"Yes, sir, the little one will go and bring him in," and then the subordinate withdrew.
