The room is very big. There is a stone table in the middle, and oil lamps are lit in the corners around. In addition, there is nothing else, and there is no sign of exit. Several people look at each other, wondering what's going on?

The key didn't work yet. It proved that they had come to the place where the watercolor beads were placed, but they were baffled by the room in front of them.

Before the crowd could react, the stone gate at the entrance was closed imperceptibly, so that they had no way out.

"The door is closed." Wan Sihan frowned slightly and pointed to the direction of the door.

"Then we can't get out." the air here is not circulating. If we stay for a long time, we will die of hypoxia.

"There must be another exit." Yan Xiaoxi looked around, hoping to find a clue.

"Xi'er is right." Nangong Lin agreed.

"However, there's nothing here. It's really difficult to find an exit." beibaishi said the key question.

"Let's look around." then wansihan took action, and they had to go out as soon as possible.

"Think carefully about what you can do to find them." Xi Wenjian was also confused. He looked at everyone in a posture of standing and talking without back pain. So many people here are extremely smart people, and he can't worry about them at all.

What he has to do is to firmly grasp beimengxi, so he is not afraid of their tricks.

Thinking of this, Xi Wenjian sat down at the only table in the house, let Bei Mengxi sit beside him, and tasted the tea leisurely.

Several people gave him a white look, but they continued to look for clues.

Nangong Lin wants to rush over and punch him. This is where he and the mask don't care about beimengxi's life and death. However, he can't do so. Who let his quilt fall on the hand of a woman named Yan Xiaoxi.

Beimengxi has helped her many times. She will never let her go.

Some of them are. She does have some meddling. However, this is her advantage. She has a human touch they don't have, and always maintains a kind and grateful heart.

Yan Xiaoxi also couldn't stand xiwenjian's lofty posture. He was the Lord. Yes, the people here were lower than him and had extraordinary life experiences. He ordered them like an emperor. Considering the safety of beimengxi, no one had an attack. He was trying to find out his mouth and bear it.

She went to Xi Wenjian's side and glanced at him and looked at Bei Mengxi. Bei Mengxi was staring at the chessboard on the table. If she hadn't noticed her eyes, Yan Xiaoxi hadn't noticed that there was an inconspicuous small chessboard on the table, with ten black-and-white pieces on it and no chess box next to it. It didn't look like go.

Slightly frowned, she did it. She wanted to pick up the chess piece, but she was interrupted by Xi Wenjian's voice: "don't move."

It looks like a very dangerous place here. How can you move the things inside casually? You have to be careful.

Yan Xiaoxi raised his head in surprise, held his hand in the air, and suddenly retracted his hand.

"Sister Xi'er, what's this?" Bei Mengxi couldn't understand what was going on with the chessboard in front of him. He asked and wanted to get an answer from Yan Xiaoxi.

Yan Xiaoxi shook her head and thought, if only she knew what this is, but her intuition told her that this chessboard has a certain connection with the export. As for its role, it remains to be considered.

The three people's dialogue attracted everyone's attention. They all came over and looked around on the chessboard on the table.

"This is not go." Nangong Lin gave a positive answer.

"It doesn't have much to do with the five elements and eight trigrams." Wan Sihan knows a little about these aspects.

"What chess game is that?" obviously, North Percy couldn't see any clue.

"Don't know?" Wan Sihan puzzled yaotou.

"What are you doing here? Hurry to find the exit." xiwenjian said again in an ordered tone.

The people looked at him at the same time and ignored his existence. The reason why they were so anxious was to care about people's safety. The imperial mausoleum was already underground. This room was a stone chamber. If they stayed in a closed space for a long time, they would suffocate and die.

Yan Xiaoxi stood up, walked around the room and looked around.

Apart from the table, there are only candles around. What's the connection between all this.

"In fact, these seemingly unrelated items, such as water, flour and donkey, can be made into cakes by combining them. This is our situation now. We can find the exit by putting all the clues together." beibaishi felt that this secret room was very similar to the dark room of the mother of the North moon country.

After his reminder, Yan Xiaoxi remembered what had happened in Beiyue country, nodded frequently and said, "but there is nothing in it for us to study deeply."

It's really open space.

"Maybe it's easier to choose from many things. There are only these things in front of us," Wan Sihan said.

Wan Sihan and Bei Mengxi couldn't understand what they were talking about. They stayed in place quietly and couldn't insert a word.

Xiwenjian has a bottom in his heart, but he plans to completely leave it to them.

"You mean chessboard, table, stool and candle are switches?" Yan Xiaoxi, who is so smart, said at a glance.

"Very likely." North Percy himself was not sure.

"What do you think?" Yan Xiaoxi felt that he had no clue.

"It was dark all the way. Only here were lights and candles." Nangong Lin said the key question.

"It's really strange," Wan Sihan realized.

"Maybe that's the clue." beibaishi thought maybe the candle was the breakthrough.

"Let's look separately." Yan Xiaoxi said.

"OK," several people said in unison.

Looking at the heated discussion among several people, Xi Wenjian still ignores it. As long as he goes out from here, it doesn't matter who finds the opportunity.

Yan Xiaoxi, Nangong Lin, Bei Boxi, and WAN Sihan's dead men walked to a corner and scattered to find out what the secret of the candle was. Their pace was slow and cautious, and their eyes were on the candle.

After careful observation, I think it is no different from ordinary candles.

"Did you find anything?" Yan Xiaoxi asked.

"No." Nangong Lin took the lead in giving a conclusion.

"Is it true that candles are only used for lighting?" beibaishi looked back suspiciously and looked at the direction of the table. In this way, the breakthrough is still looking forward to.

What you get with joy is still nothing.

Several people gathered at the table again.

"Can that piece move?" Wan Sihan asked, pointing to the white piece on it.

"Do you want to try?" beimengxi also participated in the discussion team.

"Nangong Lin, what do you think?" Yan Xiaoxi asked his opinion.

"Why don't we try?" beibaishi felt that the current situation was very dangerous and could not be worse.

Wan Sihan and Nangong Lin looked at each other and replied together, "OK."

Xiwenjian was really regarded as a transparent person by them, and no one saw him. However, there was another person who was regarded as a transparent person. They almost forgot the mask and followed them into the room. From entering the house, he stood in the corner without moving a step. He was forgotten and ignored like a sculpture.

"There should be no danger." Nangong Lin said this to show that he wanted to try.

"Wait." Yan Xiaoxi pulled Nangong Lin in time.

"Xi'er?" Nangong Lin understood the meaning of Yan Xiaoxi's eyes. She didn't want to take risks by herself.

However, he has never been a person to escape.

What's more, it's just a chess piece. There's nothing terrible.

"Well, I'll do it." North Percy volunteered.

"Brother." beimengxi called his brother, and his eyes looked more and more at Wan Sihan.

Here, they all have people who care.

"It looks like I'm the best fit." only the mask is alone.

Everyone was silent and looked at the mask approaching the crowd.

"Mask, you don't have to" Yan Xiaoxi wanted to say that you don't have to do these things.

"We are friends. Why, do you only treat me as an outsider?" a sentence stopped everyone's mouth.

"Xi'er, don't worry, it's okay." Nangong Lin held Yan Xiaoxi's hand and saw the worry in her clear eyes.

"Don't worry, it's all right." then the mask put his hand on the altruistic recent white chess piece and tried to pick it up, but he found that the chess piece was firmly stuck on it, unable to move and take it out.

Everyone was nervous and careful to pay attention to the action of the mask. They were relieved when they saw that there was no danger.

Now I know that the chess pieces can't move.

"Do you see whether the gap on the chessboard moves the track?" there is a cross line on the chessboard. If you don't pay attention to it, it's really difficult to find this, and you'll take it as a normal chessboard.

Hearing Yan Xiaoxi's words, all the attention focused on the chessboard again, including Xi Wenjian.

"In this way, children can move chess pieces." Nangong Lin quickly thought of this.

"Yes, it should be the key to opening the exit," North Bosch agreed.

"But the chess piece can't move. How can it move?" Wan Sihan said.

"Have you ever thought that there are other things that can be moved in this room? It controls the chess pieces so that the chess pieces can be moved." the mask put forward his own point of view. His words are based on it. When they think the candle is useless, he happened to find the secret of the wax candle.

"What did you find?" Yan Xiaoxi thought the mask wouldn't talk in vain. He must know something that everyone didn't notice.

The mask looked at Yan Xiaoxi in surprise, pointed to the candle in the corner and said, "it can rotate."

"What?" Wan Sihan cried out in shock. He never thought he would hear the answer.

Then, the mask walked into the corner under the eyes of the people, put his hand on the candlestick and gently twisted it. A magical scene happened. The black chess piece on the chessboard moved to the left. As expected, as he guessed, the candle is the tool to control the chess piece, and the chess piece is the mechanism to open the secret room.
