Hearing Yun Xi's words, Tang Qixing immediately became excited, "Shu Lie Yun, what do you mean?" He raised his hand and pointed to the lock door of the machine lock that suddenly opened on the wall. "Do you already know how Yao Guangbai stole the treasure?"

This question pierced into Yang Tuo's heart like a sword, causing his pupils to shrink suddenly, and his face turned pale in an instant, "After I woke up, Yun Xingfang and Tang Tiqi checked. The copper door mechanism was intact, and there was no sign of prying the protection on the hidden lock. However, the key was completely destroyed before. How did Yao Guangbai open the bronze wall?"

Yunxi walked up to the wall and looked at the structure of the mechanism lock carefully. It was indeed different from ordinary locks. The three key holes were hidden under one layer of protection, and there was no regularity between the positions, one was far away from the other two.

She murmured: "The answer is actually very simple. Yao Guangbai uses the key."

Li Ru, who had already cleaned up the vomit and had some strength to recover, looked up in surprise when he heard this, with tears still flowing from the corners of his eyes, and asked in a hoarse voice: "But the key is not already..." As he said that, he couldn't help coughing again.

Yang Tuo hurriedly stepped forward and bent down and gently patted Li Ru's back.

"I said before that the triple keyholes are linked together and must be turned at the same time to open it. Without a key, even the best thief, it will take a lot of time to pry the lock open. It will never be possible to pry it open within a day or two." Yunxi turned his face and looked at Yang Tuo steadily, "But he stole the Bai Lianzhu during the short period of our coma, leaving no trace of the lock prying. So even if he was unbelievable, the key was still stolen by Yao Guangbai."

"Not to mention how he stole the key, how did Yao Guangbai come in from the secret room?" Tang Qixing reached out to check in the bronze wall mechanism, but as expected, he found nothing.

"And why did you say that Bai Lianzhu is on someone in the room?..." Tang Qixing turned around and looked at Yunxi with complicated eyes. "Does Yun Shuli suspect that there are Yao Guangbai's accomplices among us?"

"Agree?" Hearing Tang Qixing's statement, the leader of Yang couldn't help but take a step back. He looked around everyone in the room with fear, "If there is really a relationship, isn't this too scary?"

Yunxi didn't look nervous at all. He shrugged and looked at Team Leader Yang, and smiled sweetly, "It's too early to say that he has a fellow party member. Let's check the entrances everywhere first."

As she said that, she walked to the steps of the entrance, looked up at the machine door above, and asked loudly: "Sir Yang, come and check if there are any signs of this door being opened and closed?"

Yang Tuo stood up, walked to Yunxi, looked up carefully, and said with certainty, "No, no one came in, and no one went out."

Yunxi was a little surprised, "Why are you so sure?"

Yang Tuo raised his hand and pointed to it, explaining: "This door has a unique design. There is a movable small wooden stick on the fixed roof next to the movable door leaf. A simple mark is drawn behind the wooden stick. The vibration of each door leaf is closed and opened will cause the wooden stick to rotate. Each vibration is different. So after closing the door, the person in the secret room will look up at which mark the stick is parked, and then you can compare and check whether the machine has been moved."

Yunxi looked along his fingers and saw a wooden needle as big as a toothpick on the roof next to the movable door, which was very hidden. It was not Yang Tuo's special guidance, so others would not notice it.

Yunxi asked Yang Tuo to open the mechanism and left the rest of the people in the secret room. He followed Yang Tuo to the outside room and opened the door of the study.

At this time, the sky was already dark outside, and everyone in the yard had lanterns and torches. Several inspections were fully armed and inspected, without any abnormality.

Yunxi explained Yang Tuo in advance that he would not reveal the stolen matter in the house, but just pretended to be normal patrol and interrogation.

When the people outside the door heard the movement, they quickly stepped forward and asked Yang Tuo what he had ordered.

Yang Tuo looked around the yard with a gloomy face before speaking in a deep voice, "Is there anything wrong with the front and back of the study?"

A leader in front immediately knelt on one knee, pressed the sword at his waist and replied respectfully: "Report to the adults, there is no abnormality. All the doors and windows of the study did not leave anyone for a while, and there was no abnormality. Even the roof and walls of the house were standing on several brothers holding torches and illuminating it, and there was no abnormality!"

Yang Tuo looked back at Yun Xi, and both of them looked dark.

"Continue to patrol, don't be slackened."

The leader raised his hand and bowed aloud and replied: "Don't worry, sir! Brothers are all shocked!"

Afterwards, Yang Tuo and Yunxi turned around and returned to the room and locked the door firmly.

"Sir, are there any other entrances and exits in the underground secret room besides the machine door? For example, vents or something." Yunxi asked with a frown.

Yang Tuo answered very simply without any hesitation, "There will definitely not be any. Those vents are specially designed, with very small diameters. It is estimated that only mice can pass through, and even smaller cats cannot do it."

"Then did you see the drip when you woke up? How long have we been in a coma?"

Yang Tuo thought for a moment and replied hesitantly: "I took a look. We should have been in a coma for less than half an hour."

Yunxi was thinking secretly.

It takes about an hour to put it in modern times.

In other words, Yao Guangbai only took sixty minutes to appear in the secret room, complete the poisoning, stunned everyone, opened the theoretically unopenable safe, stole the treasure, and disappeared out of thin air with the treasure, this series of complex and difficult tasks.

In fact, Yunxi was prepared for Yao Guangbai, but in such a short time, it was far beyond her expectations that everything was so beautiful.

Yunxi narrowed his eyes unconsciously, his eyes passed through the square entrance in front of him, and shot into the deep secret room like an awl, with a smile on his lips.

Yao Guangbai, Yao Guangbai, this means that you can really go to the nine heavens to steal the moon, I will believe it!

You have such surprises, which makes me feel a little reluctant to catch you!

"Shu Lie Yun, what's wrong? But what's the clue?" Yang Tuo looked at Yunxi's indescribable strange expression, and hesitated for a moment.

Yunxi stopped in front of the entrance of the secret room, raised his hand to Yang Tuo, made a call, and said with a smile: "Sir, don't be impatient. When you return to the secret room, you will allow your subordinates to analyze one by one."

Yang Tuo was still a little unwilling to accept it, as if he had too many questions and wanted to ask them clearly at once. However, seeing Yunxi's calm but unquestionable look, he didn't say much, and lifted his clothes and leaned down the stairs.

Yunxi also followed behind, walked slowly down the stairs, and returned to the underground secret room again.

Everyone in the secret room was tilting their necks, waiting for them to come back.

"Sir, is there any abnormalities outside?" Tang Qixing asked anxiously.

Yang Tuo glanced at Yunxi, saw her smiling and nodding, and then he explained everything just now.

After hearing Yang Tuo's words, everyone became even more confused.

"The door has not been opened, and there is no movement outside, but we are all poisoned, and..." Team Leader Yang, who was beside Li Ru, looked at the opening of the wall, and his brows became tighter and tighter. The more he said, he felt terrible, "Is that Yao Guangbai a ghost? Can he pass through the wall and pass through the room?"

"Ghost?" Tang Qixing couldn't help but cover his lips and chuckled, "If it was a ghost, things would be difficult."

Yunxi glanced at them coldly, then looked at the cold Yunnan, which was calm and unmoved, and could not help but complain:

There is a real half-ghost in this room, and I don’t see how easy or difficult it is to deal with it.

It has to be said that the two ghost messengers are really cheating. They want to give Yunnan a process of slowly becoming humans, and they will not take away all their supernatural abilities as ghosts, so they will not be left at all.

If Yunnan has some superpowers, the brother and sister will not really start from the bottom of the officials of the selves of the punishment room.

"Where are you, Shuli Yun?" Tang Qixing asked Xiang Yunxi with a smile again, "Don't you think the ghost is difficult to deal with, do you?"

"It's hard to deal with? The situation is clearly easy to deal with," Yun Xi smiled slightly, turned to everyone, with a faint look, "Since there is no one in and out of the secret room, it proves that Yao Guangbai is in this room!"

This time, almost everyone was shocked on the spot!

This statement is more than ten times more terrifying than Yao Guangbai’s accomplices in the house!

People looked back at each other, looked at the faces of the people around them, and a layer of cold air appeared on each other's back, and the atmosphere in the house instantly frozen to the freezing point.

"This...is unlikely?" Team Leader Yang swallowed his saliva without hesitation and said hesitantly.

"Did Yao Guangbai use disguise?" Tang Qixing was even more alert and pressed his hands on the Xiuchun Sword, looking at everyone around him with caution.

"It may not be just disguise, but we have to be careful of disguise." Yun Xi's face darkened and he turned to Li Ru, "Li Workshop, although you are in charge of the workshop, you should have been involved in the tricks and skills of disguise, right?"

With the help of Team Leader Yang, Li Ru stood up with difficulty and nodded weakly, "I do understand something. Yun Shuli has something to say, but it doesn't matter."

Yunxi nodded, "So is there any way to quickly identify if someone disguises themselves?"

Li Ru paused for a moment, thought for a while, and said in a deep voice: "Yes, no matter what disguise technique, the materials used must be elastic and shaped. This kind of materials have a common characteristic: they are afraid of water and sweat. Therefore, the simplest way to identify is to rub their faces hard and wash their faces."

Yunxi raised his eyebrows and smiled without realizing it.

It seems that ancient disguise materials are not like modern ones. There are many advanced materials similar to rubber, plastic, and films, and their shortcomings are still very obvious.

"Okay!" Yunxi clapped his hands heavily, "It just so happens that we have all the toiletries here, so let's start with washing your face!"

Later, under Yang Tuo's command, Team Leader Yang, Yunxi and Tang Qixing took out two basins from the inner lounge, filled them with water, and took two towels and placed them on the table in front of the copper wall.

Yunxi moved the timing drip, freed up a piece of land, put the basin and facial towel, and smiled at everyone, "There is only a woman in Yunxi in this room, I am the first to wash it!"

After saying that, she proudly stacked her sleeves, revealing her two white wrists, and was about to lift her water to wash her face.

At this time, Yunnan suddenly coughed lightly. Yunxi suddenly looked up and found that Yunnan was blocking his face. He whispered unhappy: "Just say that everyone in the family treats you as a boy, you can't really forget that you are a girl!"

Although Yunnan was blocking it, Yunxi still saw that the men in the room were shocked by her rude movements of her cuffs, and her eyes were all wrong and stared at her arm.

She quickly put down some cuffs, enduring the mistake in her mouth, but cursing her mother in her heart.

It is really a feudal old society that suppresses human nature.

Yunnan then made way aside and asked everyone to see all the actions of Yunxi washing his face clearly.

Yunxi rubbed hard and then rubbed his face carefully with a towel. The water in the basin was as clear as before, and it was not turbid.

"It seems that the clerk is indeed fine," Tang Qixing smiled and said, "I just saw that the clerk did not give the man's courage, and I really suspected that you were a man pretending to be a man! When I saw this, I was innocent, but I was like a fake daughter!"

Yunxi glared at him fiercely without fighting back.

Next is Yunnan. Yunnan was washed very carefully, and the result was naturally the same as Yunxi, with clean water in the basin.

Next was Yang Tuo. He chose another basin of clean water and washed it carefully, but there was no abnormality.

Tang Qixing was the fourth one. He chose the basin of water that Yunxi used. Before washing, his face was swollen and covered with scars after being beaten. After washing, it was still the same.

Yunxi also asked Yang Tuo to touch the swollen part of Tang Qixing's face after washing it. Because only Tang Qixing's face has these obstructions, it is very easy to be counterfeited.

But the final result is still no abnormality. Those scars are real existences.

Finally, there are Li Ru and Team Leader Yang.

In fact, Li Ru and Yunxi didn't need to be tested at all, because they were the most poisoned, and when they woke up, they were wiped with cold water. Especially Li Ru, who was sprayed with a big mouthful of tea by Yunxi.

Their faces have been wiped many times.

As for Team Leader Yang, there was nothing unusual.

This time, the situation was in a deadlock.

"No one was faked?" Team Leader Yang still found it difficult to accept this fact.

"Indeed, this fact is hard to accept." Yun Xi picked up a towel, wiped his hands, and his expression was still calm, as if he had expected this result, "because this means that Yao Guangbai did not disguise himself as someone."

"That's when we have his accomplices here!" Tang Qixing looked at everyone with sharper eyes.

"Having an accomplice is also one of the possibilities." Yun Xi nodded.

"The Bailianzhu that Shuli mentioned before might be on us, so what do you say?" Yang Tuo seemed to remember something and asked, "Do you still need to test your body?"

Yunxi nodded disapprovingly, "That's right, after washing your face, you'll be able to test yourself."

"But," Tang Qixing touched his chin and stared at Yunxi with a smile on his eyes. The smile was really weird, "Yunshu Lie, aren't you a daughter? We are all men in the room, if you don't let outsiders in, who will search for your body?"
