After Pei Yun learned from Zheng Qiye's mouth that the ghost who looked like a civet cat specially picked Yang Su to sneak into the mansion at night when he was not in the mansion to steal, he was even more convinced of his previous guess, so he did not reply to Mrs. Zheng directly, but only told her to act as usual, and she had her own way of catching ghosts and eliminating demons.

After saying goodbye from the Yueguo Mansion, Pei Yun went to the forbidden army garrison again to find Qu Tutong, and secretly instructed him to send someone to the Yueguo Mansion to prepare everything, and then returned to the Jin Palace.

When Pei Yun returned to the Jin Palace, he had already seen that Peng Yuzan had personally selected more than a dozen capable palace guards, intending to lead them to Lanzhi Palace to strengthen the vigilance. In this regard, Pei Yun only smiled faintly, and did not say anything to Yu Zan, and returned to his dormitory and fell asleep.

After sleeping for nearly four watches, Pei Yun quietly got up, changed into a night suit, slipped out of the palace alone, and ran straight towards the Yueguo Mansion.

The alley where the Yue Guo Mansion was located was dark and silent, Pei Yun hid behind a big tree in the dark, and probed his head to detect the surrounding movements.

After less than a quarter of an hour, I don't know from which corner suddenly heard two cat meows, Pei Yun was overjoyed, busy holding his breath and concentrating, looking in the direction of the cat's meow, with the help of the dim moonlight in the sky, it was vaguely visible, and a gray shadow jumped over the wall unusually quickly and rushed into the Yue Guo Mansion.

Pei Yun was secretly surprised: I didn't expect this beast to be so bold and steal tonight! Just when he was surprised, he suddenly saw that the gray shadow only stopped in the mansion for a moment, and then jumped out again and slipped away towards the alley.

Oh, it turns out that this beast is just here tonight to detect the movement and see if there is an ambush inside and outside the Yue Guo Mansion! Pei Yun thought so, and ran down with the gray shadow closely.

I didn't run long before I saw the gray shadow in front of me turn into an alley and disappear. Pei Yun kept in mind the location of this street from afar, and then turned around and returned to the Jin Palace.

At the end of the next day, Pei Yun changed his outfit, and when the streets of Chang'an were crowded, he came to the street where the cat ghost might be hiding according to the direction he had recorded in his heart last night.

To his great surprise, there was only a small courtyard in the alley where the cat ghost returned to hide last night, and there were two strong men in civilian clothes and swords standing in front of the courtyard. As soon as the two strong men saw Pei Yun approaching, they immediately stared at him with raised eyebrows and strengthened their vigilance.

Pei Yun pretended to be on the wrong path, smiled and arched his hand at the two strong men, and quickly turned around and left the alley.

When he found Qu Tutong at the garrison of the forbidden army, and described to him in detail the location of the alley where the cat ghost was hiding, as soon as he inquired, Pei Yun couldn't help but gasp: he never thought that the cat ghost would actually hide in the heavenly prison!

After asking Qu Tutong again, Pei Yun was even more stunned: the person in charge of guarding the prison turned out to be Dugu Tuo, the half-brother of Queen Dugu Jialuo, the right leading general!

Qu Tutong had received a secret decree from the emperor yesterday, knowing that Pei Yun was secretly investigating the case of haunting in the palace under the order, at this time, listening to Pei Yun constantly asking him about the situation in the prison, he also guessed a little bit of the reason, and couldn't help but remind Pei Yun: "Pei Du Ji Office, do you want to report these situations you found to Niangniang?" ”

Pei Yun nodded subconsciously, then shook his head again, and muttered to himself, "How can this be?" ”

"The last general advises you, this matter is not trivial, if you can't find enough evidence, you must not act rashly, so as not to invite trouble." Qu Tutong saw Pei Yun's dejected appearance, and persuaded him again.

"General Qu, from today onwards, please send more capable men to keep an eye on the prison for twelve hours, and everyone who has been to the prison and has dealings with Dugutuo must be written down and reported to me." Pei Yun came to his senses and explained to Qu Tutong.

"Then, do you want to ...... over there in the Yue Guo Mansion?"

"If everything is business as usual, do you estimate that it will take a few days for the Yue Guo Mansion to be completed?" Pei Yun seemed to have made up his mind and asked Qu Tu Channel.

"It will be completed in three days at the latest."

"Well, you must give an account to your subordinates during these three days, and you must not omit everyone who has been to the prison." Pei Yun very solemnly instructed Qu Tu Channel.

Despite this, Pei Yun still felt relieved, for three consecutive days, he was a night walker, insisting on going to the Yue Guo Mansion every night to personally monitor the movements of the cat ghost.

It is also strange to say that for three days, the cat ghost has never come to the Yueguo Mansion to steal. Not only that, but the sergeant sent by Qu Tutong to monitor the prison also reported that he had never seen a cat ghost emerge from the prison courtyard.

It wasn't until the fourth day that Pei Yun took over a list of recorded names from the sergeant who had monitored the movements of the Heavenly Prison on the previous day, and finally found a name he had been looking forward to seeing from among them, and a smile appeared on his face.

It was also on the night of the same day that Pei Yun had just come to the ambush outside the Yue Guo Mansion when he heard a commotion from inside the courtyard wall: "The ghost has caught ......."

Pei Yun was in good spirits, and hurriedly knocked on the door and entered the courtyard to take a look, only to see one or twenty people from the Yueguo Mansion holding torches had gathered under the south courtyard wall, shouting and shouting under the courtyard wall, Pei Yun showed his identity, separated everyone and looked at the root of the wall, and saw that he had previously secretly instructed Qu Tutong to send people to dig a three-zhang deep trench along the courtyard wall of the Yueguo Mansion, and indeed a monster that looked like a civet cat was trapped, and the monster was trapped in the trench, still jumping, screaming and screaming, trying to jump out of the trench and escape.

Seeing this, Pei Yun rolled his eyes, snatched the torch from a family member next to him, and threw it at the cat ghost in the trench, shouting: "Throw the torch and burn this beast to death." ”

That night, Yang Su was still on duty in Shangshu Province, and the people of the Yang Mansion were already a little jealous of this cat ghost, and when they heard Pei Yun ordering them to burn this monster with fire, they threw the torches they were holding in their hands into the deep pit.

The monster was aroused by the fire, and it screamed strangely, jumped up to a height of two feet on the ground, and pounced in the direction where Pei Yun was standing.

It's too late, it's fast, just the moment when the cat ghost stretched out his sharp claws and grabbed the door in front of Pei Yun, Pei Yun shouted, pulled out the saber on his waist, and slashed at the cat ghost head-on with a "brush", cutting off a cat head bloodily and rolling down into the trench.

Seeing that the cat ghost whose head was cut off by his sword fell into the trench, tossed a few times, and never moved again, Pei Yun let out a long sigh on his back, and immediately ordered the Yang Mansion family to go down to the trench and carry the body of the cat ghost and the head together......
