Watching the crowd leave, the old man grinned, revealing his red gums and a few yellowed teeth.

"Haha, what a bunch of idiots, even their own traps."

At this moment, three figures quietly appeared outside the cage, which were Xin'er, Lu Qiuhao and Ying Meng!

It turned out that the three of them had not left just now. As early as the beginning, Xin'er noticed the old man. Although he always turned his back to the cell, he was actually observing everything outside the cell. Especially when the three of them came here, the old man turned his head from time to time to look at the three people.

Although it was only a short moment, it was still keenly captured by Xin'er. From the old man's eyes, Xin'er saw appreciation and kindness, and did not feel hostility, so Xin'er did not choose to leave, but chose to believe the old man and believe that he would help them get out.

Facts have proved that Xin'er guessed correctly. With what she said just now, the soldiers outside should not choose to enter this dead end for a while.

He turned around slowly, Xin'er looked at the sloppy old man and bowed, "Thank you for helping me, one day, we will repay you."

The old man sat up, looked at Xin'er with appreciation, and said, "One day, it's your chance to repay me now."

Xin'er was stunned at first, looked behind her, but didn't hear anything, then she said, "I wonder how senior, how do we want us to repay you?"

The old man did not rush to answer Xin'er's question, but touched his dirty beard and looked at Ying Meng and said, "Girl, if I guess correctly, you should be the princess of the Song Dynasty Empire, Yuan Ying Meng, right?"

"How did you know?" Ying Meng said in surprise.

The old man smiled slightly, raised his head and said, "I really didn't want it. The princess of the enemy country actually came to our Yuantuo Empire. It's really rare... No, our two countries are not enemies, but family members. Shouldn't it be normal for families to visit each other?"

When the three of them heard this, they couldn't help but look surprised: This guy seems to know the truth very well!

"Time flies so fast. When I first met you, you were still a little baby who couldn't even walk on the road. Unexpectedly, in the blink of an eye, you grew into a graceful eldest daughter. The guy named Lu was so lucky. How could I not have such a good fortune to have such a beautiful daughter-in-law!"

When Ying Meng heard this, her face turned red instantly. Although Lu Qiuhao was embarrassed, the surprise in his heart was far greater than shy. This old man knew more about things, he really did!

Lu Qiuhao stood in front of Ying Meng and said, "Who are you!"

The old man smiled slightly: "Haha, little Lüzi, how long has it been since you saw me? Can't you recognize me?"

Listening to this familiar title, Lu Qiuhao was slightly stunned. He looked at the old man carefully and couldn't help but exclaim: "You are... the Moon Master!"

Not bad! This person is Sheng Mingyue, the former national teacher of the Yuantuo Empire!

Looking at the sloppy and old man in front of him, it was hard for Lu Qiuhao to imagine that he and Sheng Mingyue, who once guided the country, were the same person.

He stretched out his hand tremblingly, and Lu Qiuhao pointed at Sheng Mingyue and said, "But Mr. Yue, you should have already..."

"It's dead, right?" Sheng Mingyue said.

Lu Qiuhao nodded with a meaning.

Sheng Mingyue sighed and said, "This matter... has been a long story."

Turning his head to look at the three of them, Sheng Mingyue continued, "You guys are going to go to the key room to get the key to save Lu Jin, right?"

The three of them nodded.

"Then let me save me by the way. If we can really get out of here, I will tell you the matter."

"It's time for you to know the truth when things have developed to this point..."

The three of them looked at each other and nodded.

Sheng Mingyue took out a rag from her arms and handed it to Xin'er, "You have taken this drawing, there are various secret doors on it. With him, you can avoid detours."

Xin'er took the drawings, looked carefully, and said, "Senior Sheng, how did you know the location of these secret doors?"

Sheng Mingyue smiled slightly, "Because I designed this prison."

Slightly narrowed his eyes, Xin'er discovered that the war between the two countries was becoming more and more confusing, and the "truth" of the facts became increasingly difficult to guess.

Carefully put away the rag, Xin'er put aside her thoughts, nodded, and followed the instructions on the drawings, Xin'er stuck it on the surrounding wall. After stroking back and forth for a while, she found that a piece of turning on the wall was slightly loose. With a light press, the brick fell into it.

"It's cross!"

The wall opposite opened, revealing a secret passage.

Looking at the secret passage, Sheng Mingyue nodded with satisfaction, "Tip, my cell key is in the fifth row and sixth row on the left wall on the door; the key to Lu Jin's cell is in the first drawer of the right cabinet in the door."

Xin'er thought for a while and said, "Where is the key to the fourth underground prison?"

Sheng Mingyue raised her eyebrows and said, "You girl is so stupid. She still wants to do such a thing."

Having said that, Sheng Mingyue still told Xiner the location of the fourth floor of the underground prison key, "The fourth, fifth and sixth rows on the right side of the door are all the keys on the fourth floor of the underground."

Xin'er smiled a little badly: "I understand, thank you Senior Sheng."

"Hey, I warn you, don't let too many people out. No one on the fourth floor of the underground is easy to mess with. There are too many people, and the security system here can't handle it at all."

"Don't worry, we have a sense of responsibility."

As he said that, the three of them walked into the secret door and we closed it.

Looking at the background where the three of them disappeared, Sheng Mingyue lay down again.

"It seems that there will be a big stir here today."

"I hope this fragile undersea prison can withstand such a big disturbance."

...

Xin'er and the other two were walking through the secret passage according to the instructions of the map, and soon walked out of the secret passage.

In order to avoid being discovered, the three of them had already covered their invisible handkerchiefs before coming out of the secret passage. Fortunately, there were no soldiers around the exit of the secret passage. The three of them were in a dark dead end. Opposite the alley, there was the key warehouse where the keys were stored!

However, there are a large number of defenders outside the key warehouse. The strength of these defenders is very strong, with an average strength of about level 55.

It seems that the enemy is very clear that their purpose is to save people, and to save people, they need keys, and the keys are kept in the key room. Therefore, as long as they keep the door of the key room, they will not be able to start rescue.

The three of them hid in the alley, looking at the soldiers densely packed with keys, and couldn't help but sigh.

With so many people holding hands outside the door, it is definitely not possible to break through hard. The only way is to take advantage of wisdom!
