Mei Yingxue stayed in the front yard with a thoughtful face. Yingchun looked at him curiously several times, but it didn't attract his attention, which made Yingchun feel bored with himself, so he simply went to the east corridor and sat down. Not long after, Chu Yunfei walked out of it, still holding the letter in his hand, and handed it to Mei Yingxue casually when he passed by.

"You've been plotted!" Mei Yingxue shouted in a low voice, saying in her heart that this guy is not a woman.

"I hope I was plotted by a big beauty." Chu Yunfei smiled bitterly.

Although it was difficult for Chu Yunfei to solve the mystery of Yinliang's disappearance out of thin air, since someone had set up a suspicious formation, he would definitely leave clues. He made sure that there were no traces left on the wall of Jia's courtyard before focusing all his attention on the gate. He believed that there was absolutely no such strange legend as the wall-piercing technique in the world, and if the green peony wanted to take away so many silver taels, it would inevitably go through the gate. According to the janitor, when Mrs. Jia made a lot of noise in the morning, he took a special look at the door, and it was indeed bolted from the inside, there is no doubt about it.

When he said this, the janitor looked a little panicked. Obviously, with Ruyi, he is afraid of becoming the next Ruyi, so he is naturally very careful when he speaks. At this moment, Mrs. Jia rushed out of it and looked at Chu Yunfei with a very impatient expression, "He's right. All can testify. I don't believe it! There are even moles among so many people! Absolutely impossible! ”

Chu Yunfei knew that it was unlikely that there would be a mole in the Jia family, because since Ruyi's identity was exposed, including the janitor, two or more people ate and lived together, the purpose was to supervise each other. Even if there are still people who want to do it, I'm afraid it will not be an easy thing to do. Moreover, after the Ruyi incident, Mrs. Jia has already checked everyone's background and is sure that there is no one to doubt.

"Is it a secret room case?" Mei Yingxue was very worried.

Chu Yunfei only listened to Mei Yingxue's tone and knew that he had something on his mind. But now is not the time to listen to him, just nodded, came to the gate and looked inside and out several times.

The gate of Jia's house is installed with the most used gate for the rich and noble families in the city, and a pair of copper rings on the door can be locked with a lock from the outside. Inside, you can use a deadbolt. The deadbolt is a square log about half a foot thick. The place where the deadbolt is inserted is a hole made of terrazzo on both sides of the door frame, and the bolt is removed and placed behind the door during the day, and it is placed horizontally on the door at night, so that no one from outside can enter. Although the courtyard of the Jia family is not large, the gate is very tall, and the door panel is almost five or six inches thick. Because it took too long, the place on both sides of the door was already a little old, leaving a crack almost a finger wide. If it is an ordinary deadbolt, such as a small deadbolt like the one in front of Mrs. Jia's door, it is easy to use something like a knife to open it, but it is not easy to open such a thick deadbolt, because the deadbolt that weighs more than ten catties is impossible to open with something like a knife.

"You're going to help me think of an idea, how can I come in from the outside without alerting the people inside?" Chu Yunfei opened his mouth to ask Homa, and did not forget to look back at Mei Yingxue.

Homer scratched his head, then shook his head, "Are you mistaken, is it possible that they left somewhere else?" For example, the roof? ”

"Impossible," Mei Yingxue resolutely denied Homer's statement, "You must know that it is more than six thousand taels of silver, not to mention whether the roof can bear such a large weight, how to get the silver on the roof is a big problem." Also, carrying such a heavy load, you will definitely step on broken tiles or something. But I've checked that there are no tiles or dirt on the ground. ”

Chu Yunfei nodded, this was exactly what he wanted to say, but Mei Yingxue said it first. He added: "Look at it, the Jia family's house is almost ten years old, and it is covered with moss and grass, if someone has ever walked on it, it will definitely leave traces." In addition, there are not such thick trees in this courtyard, which can afford to bear thousands of taels of silver. So, if you want to leave this courtyard, you can only go through the gate. They must have figured out a way to open the door from the outside and bolt it from the outside. ”

After Chu Yunfei finished speaking, he came to the door, took out the heavy deadbolt, and carefully began to inspect it, in the sun, he found that the place near the two ends of the deadbolt seemed to be stained with fluff, especially on the right hand, which was intermittently almost a foot or so of fluff. In addition, in the very middle of the deadbolt, there are less noticeable scratches, which, judging by the color on it, are clearly freshly left. He turned back and beckoned to the janitor, asking him to demonstrate how he usually bolted the door. The gatekeeper obediently agreed, he first aligned the two doors and closed them, then took the deadbolt from Chu Yunfei's hand, and skillfully put the deadbolt into the two stone caves behind the door. Chu Yunfei noticed that when the janitor took the bolt, his two hands were very far apart, almost holding the middle of the bolt. He also discovered another important thing: the two stones that inserted the deadbolt, although they were holes, were oval in shape, protruding underneath and concave at the top, allowing the deadbolt to slide into the hole. What the hell is the fluff at both ends? Will it be ......?

Thinking of this, his eyes lit up, it turned out that this was a simple trick to cover his eyes!! Just look at the gaps in the door and all the mysteries will be solved. Resisting his excitement, he told the janitor to quickly find two finger-thick ropes, one loosely tied to the right and the other in the middle. Then, he inserted one end of the bolt into the hole in the west, and then put the end of the rope on the door, so that the bolt could be fixed, and then handed the rope to Mei Yingxue. He himself carefully closed the door, and then observed the deadbolt through the crack in the door, while directing Mei Yingxue to slowly lower the rope. Sure enough, the deadbolt fell to the east, and after a few more adjustments with the rope, the deadbolt entered the doorway to the east without any problems. It worked! Sure enough, the door was shut.

"How do you recycle the rope?" Mei Yingxue shook the rope in her hand.

Chu Yunfei smiled, this is the easiest question in the steps. Because the deadbolt is already secured, the rope tied to it can be pulled at will as long as it is not lifted up. The two ends of the rope only need to be pulled to the edge of the door crack, because it is tied with a live buckle, it only takes one finger to untie!

Since you can bolt the door from the outside, it is naturally okay to open it from the outside, as long as you have enough strength. Chu Yunfei asked He Ma to find an iron rod the thickness of a finger, inserted it along the crack of the door, and lifted it vigorously with Mei Yingxue, the door bolt fell in response, and the door opened.

It was only at this time that Chu Yunfei realized that he didn't know when, and the crowd around Jia's house was already full of people watching the excitement. There seemed to be a charming figure in the crowd, flashing by.
