However, Meng Yan's proposal was resolutely rejected by Ling Rui. Ling Rui thought that Meng Yan had just recovered and his internal strength had not fully recovered, and the guards of Mu Wang's Mansion had seen him, so it would be more convenient and safe to go by himself.

"Huh? Got a letter? At this time, the mysterious black shadow on the roof last night was uncovering the tiles to eavesdrop on the conversation of the three people, and when he knew that there was this letter in Mu Wangfu, he immediately left quickly.

"Mingming, thank you so much today, go back quickly, it's really too dangerous to be with me." Meng Yan said to Xing Mingming worriedly.

"Hmph, the county lord risked his life to find out this secret, is this attitude Brother Yan's gratitude to me?" Xing Mingming pouted a little angry, Meng Yan quickly apologized and explained that he was just thinking about Xing Mingming's safety. Although Xing Mingming showed a very unhappy emotion, she actually felt relieved and satisfied with Meng Yan's concern in her heart. Afterwards, she asked to go and see Ouyang He, who she had heard was seriously injured, and Meng Yan led her towards the wing room on the other side.

After dark, Ling Rui took advantage of the night to jump into King Mu's mansion with a light movement, and while avoiding the patrolling guards in the mansion, he cautiously entered several rooms to search, but he didn't get anything. Just as Ling Rui was leaning against the rockery in the courtyard and carefully thinking about where King Mu would place such an important object, he accidentally caught a glimpse of the butler of King Mu's Mansion sneakily holding something and deliberately walking briskly along some paths that were not illuminated by the lights in the mansion, and then the housekeeper entered a room that Ling Rui did not dare to enter and search because of the lights on before.

Ling Rui looked at the butler's anxious and somewhat frightened expression, and then he jumped on the roof lightly, uncovering a tile and trying to peek inside the house. I saw that the housekeeper disappeared for a long time after walking to the screen in the house, and since there were only walls behind the screen and no doors or windows were found, Ling Rui was puzzled why the housekeeper stayed in such a small area for so long. When the butler walked out from behind the screen, his hands were empty, and after Ling Rui heard a somewhat noisy sound, the lights in the house went out, and the housekeeper left after locking the house.

Ling Rui jumped off the roof with light power after removing a few tiles, and then he came to the screen and found that there was nothing there, but the floor under his feet felt a little loose when he stepped on it. Ling Rui immediately realized that there might be a secret door or secret room in this room, and since he hadn't seen the butler manipulating the mechanism when he was on the roof, he thought that the mechanism should be in a place that he couldn't see at the time. As Ling Rui crept around the room for a while, his elbow accidentally touched a teapot that was placed on a bookshelf, and strangely enough, the teapot seemed to be fixed to the bookshelf. Ling Rui observed for a while and then put his hands on the handle and spout respectively, and then carefully turned it about ninety degrees clockwise, and there was a sound behind the screen that he had just heard. He then ran softly over to see a staircase leading to the ground in front of him.

After some searching in the secret room, a rusty iron box locked in a corner caught his attention, but after many attempts, Ling Rui was unable to open or break the lock. As he struck the iron box with his hammer anxiously, a throwing knife shot through the entrance of the chamber and stuck into the wall next to the iron box, with a bunch of keys hanging from the blade. "Who?" Ling Rui quickly ran out of the secret room, but the room was pitch black, and he didn't find any trace of anyone. "Is it him again?" Ling Rui thought about it as he tried to open the box with the keys hanging on the blade, and sure enough, one of the keys successfully opened the box, and it contained all kinds of letters.

While Ling Rui was looking for relevant letters in the secret room by the faint light, a group of black-clothed people had quietly poured out from all sides to surround the Thousand Medicine Hall. At this moment, in the Thousand Medicine Hall, Chu Birou was continuing to infuse Ouyang He with true qi to activate the meridians, while Meng Yan was constantly gently wiping the sweat on Ouyang He's face with a towel on the side. The medicine boy walked in with a basin of hot water, Chu Birou gradually regained her strength and said to Ouyang He: "Master Ouyang, now that the deranged meridians on your body have recovered six or seven percent, remember to recuperate with peace of mind, and don't take your luck." Ouyang He nodded in agreement and thanked Chu Birou, and Meng Yan also breathed a sigh of relief.

"Master Ouyang, the shopkeeper's medical skills must be second to none in Chengdu City, how many dignitaries have broken through the threshold, and the shopkeeper has ignored it. So you must recover quickly, so that your friends in Chengdu can rest assured. The medicine boy said jokingly while washing the towel next to him.

"Okay, thank you Xiao Wu! Well? Little Wu, what did you say in your last sentence just now? Ouyang He suddenly became a little serious, and after hearing Xiao Wu repeat what she had just said, she felt a little puzzled, "After I came to Chengdu, except for Meng Gongzi and Ling Gongzi, I only knew one uncle, but he is only my elder, and he is not the kind of friend that Xiao Wu described." ”

"Little Wu, have you ever met any suspicious people before?" Chu Birou, who heard Ouyang He's words on the side, also seemed to be worried about something, and asked Xiao Wu anxiously. Xiao Wu replied that a young man had come to the store before to ask the owner of Ouyang if he was being treated here because of his injury, and explained that he was a friend of the owner of Ouyang Zhuang when he was doing business in Chengdu, and he just wanted to find time to visit the owner of Ouyang Village. Xiao Wu then said that he saw that the other party's expression and behavior were natural and didn't look like he was lying, so he told him about the owner of Ouyang Zhuang here, but it was a little strange that he left directly after hearing this, Xiao Wu originally thought that he would immediately ask if he could come to visit the owner of Ouyang Zhuang now.

"Not good!" Chu Birou seemed to understand something immediately, "Master Meng, hurry up and take Ouyang Zhuang Master into the secret passage, quick!" "It's too late, it's too fast, the sky is full of arrows and arrows flying from outside the courtyard in an instant, Xiao Wuzhong's arrows fell to the ground in response, and Chu Birou quickly used internal force to form a wall of qi to block the arrows shot towards the position of the three of them." Don't say anything, let's go! Under Chu Birou's loud urging, Meng Yan opened the mechanism at the head of the bed, and Ouyang He, who had just struggled to get up on his back and wanted to forcibly use his internal force to help Chu Birou, quickly entered the secret door next to the bed.

"Kill me!" The leader of the men in black gave an order, and dozens of men in black jumped from the roof, wielding long knives that flashed silver light and killed Chu Birou's wing. However, as soon as the people who rushed to the front entered the room, Chu Birou jumped off the beam of the room and hit the head of the man in black several times in a row, kicking them to the ground. Looking at the few people who rushed into the room again, Chu Birou turned around and quickly pulled out the double swords hanging on the wall, and then killed most of the black-clothed people who broke into the house within a few rounds, when facing the last black-clothed man, Chu Birou quickly stepped forward and jumped up with light skills and used all her strength to split the double swords, and when the black-clothed man tried his best to block the double swords, Chu Birou turned over and kicked heavily to the throat of the black-clothed man, and the strong force made him vomit blood on the spot and then crashed through the door and fell in the courtyard.

"Shoot me the arrows!" Chu Birou broke through the door strongly, and the black-clothed people in the courtyard began to fire arrows in unison, while Chu Birou brandished her twin swords to defend. In the interval between the black-clothed men changing arrows, Chu Birou turned around and waved her hands forward strongly, and a huge wave of qi knocked more than a dozen black-clothed people who were about to stretch their bows and arrows to the ground.

"You are really presumptuous, and the Thousand Medicine Hall is also a place for you to go wild!" Chu Birou said loudly in anger, and then continued to swing her sword towards the remaining black-clothed people. "Little girl, hand over Meng Yan and Ouyang He, I can spare you from death!" At this time, the leader of the men in black drew his sword to fight, and after a few rounds of evenly matched, the man in black shot a dragon slaying dart from his sleeve, Chu Birou quickly turned around to avoid it after discovering it, and at the same time she saw the opportunity to stretch out her left sword and stab the leader's right shoulder, and after the leader's movements stopped for a while due to pain, she kicked the leader down on the steps in front of the gate of the Thousand Medicine Hall again. Then several men in black besieged again, but the combined efforts of these people were still not Chu Birou's opponent. "Withdraw, withdraw!" The leader staggered to his feet, clutching his chest, and left in a hurry under the protection of the remaining men. "Hmph, a bunch of straw bales, if you can't beat it, you can run!" Chu Birou chased to the door as she spoke, and after seeing these people fleeing on horseback, she hurriedly returned to the house, at this time Meng Yan was bandaging the wounds of the injured Xiao Wu, Chu Birou also hurried up to help after seeing it, and at the same time told Meng Yan that Xiao Wu would hand over the treatment to him, and let him go in quickly to help take care of Ouyang He.

At this time, Ling Rui got the letter and returned to the Thousand Medicine Hall, after seeing the scene of corpses strewn all over the courtyard, he also ran to Ouyang He's wing in a hurry, and when he pushed open the door and saw that everyone was safe, his heart that had just mentioned his throat and eyes was also calmed down.

"Brother Meng, now that the letter has been obtained, what are you going to do next?" Seeing that Ling Rui had obtained this crucial evidence so efficiently, Meng Yan also felt a little overjoyed, and he analyzed that the only person he could really trust in Chengdu was Xing Hou, so he decided to hand over some of the letters to him so that he could present them to the emperor to expose the conspiracy between King Mu and Xiahou Xu. But Meng Yan also said that they also need to keep some of their letters, so that they can also reveal the truth on their own when the situation changes.

Early the next morning, Meng Yan took on his hat and dressed up quietly to Xinghou's Mansion, and when he walked to the most lively main street on the way, although he kept his head down and walked briskly, his somewhat conspicuous outfit still attracted the attention and suspicion of a member of King Mu's mansion. The family Ding quietly followed Meng Yan all the way to the back wall of Xinghou Mansion, and when Meng Yan got up and jumped over the wall, his face was instantly exposed in front of this family Ding's eyes.

Jia Ding hurriedly ran back to the mansion and told King Mu what he had just seen, King Mu was suddenly stunned after thinking for a while, and then went to the secret room where Ling Rui had come last night to find that all the letters in the box about his and Xiahou Xu's contact with the Tang envoy were gone. He finally realized at this moment that the situation was not good, once these letters fell into the hands of Xing Hou, it would be a barrel of gunpowder that would detonate at any time, it was better to immediately start to get rid of the people in King Jin's mansion now, so that there would be no proof of death. King Mu immediately called the housekeeper and asked him to go to the Xuanwu garrison immediately, and told Xiahou Xu to immediately send someone to transfer all the prisoners in King Jin's mansion to the Xuanwuwei dungeon, and if the other party needed a reason, he would inform him that according to reliable information, more people from the rivers and lakes would come to rob the prison today under the leadership of Meng Yan, in order to transfer the prisoners as soon as possible to avoid accidents.

Although Xiahou Xu thought that as long as he sent more troops to guard the Heavenly Prison, it was enough to deal with any scale of Jianghu forces, but seeing that King Mu was so eager to transfer the people from King Jin's mansion, Xiahou Xu also wanted to know what King Mu wanted to do this time. So two hours later, Gao Che, who returned to Chengdu, led fifty Xuanwu Wei soldiers to the heavenly prison to pick up King Jin and others under the instruction of Xiahou Xu, and then everyone under the leadership of Gao Che began to advance towards the Xuanwu Wei camp dozens of miles west of Chengdu City.

After handing over the letter to Marquis Xing and receiving a promise that Marquis Xing would definitely hand it over to the emperor, Meng Yan wanted to quietly go to the prison again, thinking that if the prison was not well guarded, he would secretly go and inform his father and mother of the news, but when he walked to the gate of the prison, he happened to witness his father and mother and other servants being taken out of the prison. Meng Yan looked a little confused and anxious when he saw the situation in front of him, and at the same time, after he saw his father and mother walking in front of the team with a tired and skinny face, he was constantly suppressing the anger in his heart and the urge to save people. Then, Meng Yan secretly followed behind the team in order to find out, and at the same time, around him, countless pairs of sharp and penetrating eyes were also looking at King Jin and Princess Jin who were walking in front of the team. In the sleeve of one of them, the sharp arrows of crossbow arrows shimmering with cold white light were slowly revealing beneath the cloud-shrouded sky.

The last rays of the sun were obscured by the clouds, and the rain began to fall slowly, drop by drop, and the storm was coming, and the thick and dark fog was about to envelop this dark tide of the land, which could not be dispersed for a long time.
