Let the system try to save the world

The group lit up the lights and walked around the house, but they didn't find any of the nine sons of the dragon on the ground.

Lu Jingming sighed, raised his head, climbed up to the roof in a few steps, and wrapped the bird-headed dragon, who was staring at everyone, tightly with his coat.

Chaofeng is the third son of the dragon's nine sons. He is the leader of the reptiles and loves danger and hope. His shape is often used as decoration on the corners of palaces.

"Right now, Ya Zi, Suan Ni, and Chao Feng have all appeared." Gu Yugui said, "Although I don't remember all of the nine sons of the dragon, I'm afraid I'll see them all here today."

"Why don't we take a look at the things in the box first?" Xiu Guo suggested.

Before Lu Jingming could open the box, the stone wall on his left side made loud banging sounds.

"Oh my god, which lunatic is smashing the wall?" Xiu Guo screamed in fear, "Isn't he afraid of killing us all?"

"Maybe he doesn't want to live anymore." Lu Jingming confirmed.

With a bang, a big hole appeared in the stone wall in front of him, and stone chips flew everywhere. Lu Jingming pointed the mining lamp at the gap in the wall, trying to see the face of the person coming.

"Lu Jingming, stop shining your headlights on me." The man said, "You've blinded my eyes."

"Xitong!" the group said in surprise.

Xi Tong retracted his dusty fist, and Xi Wanan walked out from his side and greeted everyone.

"Where did you come from?" Gu Yugui asked hurriedly.

"I dug a grave." Xitong was carrying a long object on his shoulder, which was placed in a black cloth bag. "I dug Qinxu's grave."

"I told you that we didn't dig deep enough. If we dig to the bottom, we'll find something." Xitong said confidently.

"With the depth you dug..." Xi Wan'an said helplessly, "You even dug out the groundwater."

Lu Jingming and Gu Yugui looked at each other and smiled. They believed that Xitong must have detected something underground.

He always likes to use force to solve all problems. If a problem can be solved by just digging hard, he won't use his brain at all.

"Then what did you encounter?" Lu Jingming hurriedly told the story of encountering Suanni and Chaofeng above his head. He looked at Xitong and asked.

"Qiuniu." Xitong said concisely, "The puzzle he set was to restore a song. I had solved it, but he wouldn't let me pass."

"Since he's broken, and I've found out you're right next door, I might as well punch through the wall." Xitong said, "You're wasting my time."

Qiuniu, the eldest of the nine sons of the dragon, loved music all his life.

Legend has it that Qiuniu is the most docile of all the dragon sons. He is not bloodthirsty or cruel, and he only likes music, so he does not set up puzzles that may hurt people's lives.

"Don't blame Qiuniu." Xi Wan'an held his forehead with his hand, "Just play a section for everyone to hear."

Xitong took out the thing from the cloth bag as he was told. It was a peculiar-looking string instrument with a statue of a creature with a dragon head and a snake body carved on the headstock. He sat cross-legged on the ground and played the song he had just restored.

It was unpleasant to listen to. As soon as the first note sounded, everyone frowned at the same time.

It sounds so bad. Every note is accurate, but why does it feel like it sounds both good and bad at the same time?

"No emotion at all." Xi Wan'an interrupted Xi Tong, not wanting him to continue to torture everyone's ears. He said, "Even though I don't understand music theory, I know this is definitely not what Qiuniu wants."

"You don't understand music theory?" Gu Yugui asked, "I thought you knew a little bit about everything."

"That's not the case. Everyone has shortcomings." Xi Wan'an said, "My master doesn't seem to like us getting involved in music theory. Besides, I have no interest in it, so I didn't study it."

Xitong couldn't help but look at him again. The original "Xitong" had a golden voice that could span three octaves. He was talented and could compose music and lyrics. He could easily handle any song. Otherwise, he would not have been in the entertainment industry for many years before marrying Gu Yugui.

"Mr. Gu, do you know how to play it?" Xitong handed the dragon head zither to Gu Yugui. One should know that Gu Yugui had displayed so many skills that he couldn't count them with both hands. Playing the zither should not be a problem for him.

"I'm sorry, I only have some knowledge of violin and piano." Gu Yugui declined.

It was a petty bourgeoisie specialty. Xitong took back the dragon head harp and thought of just throwing it on the ground and smashing it, so as to avoid the old dragon's residual soul chattering in words he couldn't understand.

"What's going on?" Lu Jingming asked hurriedly when he saw Xi Tong coming, "You just said there was something important, and so many people were called to come."

"What on earth is that thing?"

"Come and look at this." Xitong found a clean place, borrowed a flying sword from Xiwanan, and drew a map of the entire secret room.

Two concentric circles, the big circle inside the small circle.

The interior is divided into three rooms like a fan, and the outer circle is like a small flower drawn by a kindergarten child, with five rooms distributed around it.

"These empty spaces are filled with star sand." Xitong said, pointing at the empty spaces.

Lu Jingming and others didn’t know what star sand was, but Xitong knew.

Nothingness spread, and the star sand was the cement and gravel that the main god used to connect bricks and stones in the wall.

It can even connect the world with each other, so communicating between two stone houses is not a difficult task.

"That's not right." Lu Jingming counted again and said, "Three plus five equals eight. A dragon has nine sons, but one is missing."

"The dragon should have been coiled outside." Xitong said, "It, or he, escaped unconsciously, and this secret room was activated."

"So you mean that dragon you know?" Lu Jingming suddenly became jealous. I'm not your only dragon? He said, "You know so many dragons."

"Not only do I know many dragons, I also know many phoenixes." Xitong answered casually.

"I met Ya Zi in the outer circle, Suan Ni is in the inner circle, Chao Feng is in the outer circle, and Qiu Niu is in the inner circle again." Xiu Guo pondered, "Doesn't that mean we have to wait another circle before we can get out?"

"No." Lu Jingming took the flying sword and filled in the names of each room again, "Do you remember there is an empty room?"

"That's not an empty room." Lu Jingming looked at everyone, "It just occurred to me that since the dragon on the outermost side can run away, there's no reason why the ones inside can't run away."

"Nine out of ten, the empty room was once occupied by Yazi, and the ancestral hall should also be a room." Lu Jingming picked up his pen and wrote quickly, "So it should be, Yazi inside, Suanni outside, Chaofeng inside, Qiuniu outside."

Lu Jingming looked at Xitong, who nodded slightly to show his approval of what he said.

"If we want to get out now, we just need to find the right passage and turn around to leave." Gu Yugui said, "Find the exit of the cemetery, the well, or the ancestral hall."

"Guo Ping, I'm afraid you won't be able to handle the situation next." Lu Jingming said, "It's dangerous here. You should take Mr. Jin and the others and retreat first."

Guo Ping and others nodded to show that they understood.
