Xie Yu and Gong Mu Jiu were locked in the deepest cell of this dungeon, this space seemed to be just the two of them, silverfish and mayflies roaming, cobwebs were knotted, the room was damp and cold, and the slightest moonlight shone through a window at the top to breathe on the moss-covered stone brick slabs, impartial.

"Brother Ziqi, I'm dragging you down. Gong Mu Jiu sat on the cold stone steps of the cell, his expression gloomy.

"No..."Ben lowered his head, staring intently at the pillar of moonlight, Xie Yu raised his head and glanced deeply at Gong Yi Mu Jiu. "It was my mistake. ”

Gong Mu Jiu's teeth were locked, and an unwilling light cough came out from between his teeth. He raised his head and met Xie Yu's gaze, his eyes full of guilt, uneasiness, fear, and unwillingness. He opened his mouth, but didn't speak again, just sighed.

The cell, which had been quiet, fell into even more seclusion.

......

"Brother Ziqi, did you say there was something wrong with the wine?" "I took a drink and poured it. ”

But Xie Yu didn't seem to want to answer this question, just frowned, and rubbed his temples with one hand.

"Brother Ziqi, why do you say those people who wear masks want "Wood Machine"?" Gong Yu Mu Jiu chattered endlessly, his eyes did not have the loneliness and disappointment like just now, but instead a kind of consideration that tried to find clues from the details. "Ordinary people never take carpentry seriously. ”

Xie Yu looked up at Gong Yi Mu Jiu, and said bluntly: "Gong Lose's "Wood Machine" is 'attack', did your father tell you?"

"Hmm. Gong Mu Jiu nodded. "The carpentry technique is divided into three types: the upper and lower levels, the upper to the "people", the middle to the "soldiers", and the lower to the "secret". Among them, "Bing Yao" is "attack". ”

"You've also watched "Soldiers". Still don't understand?" Xie Yu asked.

"Hmm... What is it?" asked with a slightly embarrassed smile as he scratched the back of his head and scratched the back of his head.

Xie Yu tightened his eyelids and looked at Gong Yi Mu Jiu, and he didn't say anything for a long time.

"The people want to value the people, and the soldiers want to pay more attention to the soldiers, so what is the importance of this secret? I have never understood. Seeing that Xie Yu didn't speak, Gong Yu Mu Jiu asked tentatively.

"I don't know. Xie Yu stood up and walked to the wall, gently tapping the stone bricks on the wall, thoughtfully.

"I don't think that the 'cloud car', 'cloud ladder', 'troop carrier' and the like recorded in the "Soldiers' Essentials" can be the purpose of their contention. Gong Mu Jiu also stood up and said as he looked at Xie Yu's strange movements.

"Huh?" Xie Yu turned around and asked.

"I... I mean... The manufacturing process of cloud chariots and cloud ladders has been spread to various countries as early as the Pingwang period..."Gong Yi Mu Jiu looked at Xie Yu's unkind eyes, and his heart was stunned, and his voice became smaller and smaller.

"Then let me ask you something. Xie Yu stretched out his hand to Gong Mu Jiu. "Give me your jade first. ”

"You say. Gong Mu Jiu waited for Xie Yu to ask a question, but there was no movement in his hand.

"One piece will do. Xie Yu pointed to the jade pendant on Mu Jiu's waist.

"Oh... Okay..."After a moment's hesitation, Gong Yu Mu Jiu slowly took off the bottom Hengyu on the left and handed it over.

"Which of the three styles do you think is the most important?" Xie Yu rubbed the jade in his hand, and handed it to Gong Yi Mu Jiu without raising his head.

"Naturally, it's "Secret", my father only let me watch it and didn't let me learn it. Gong Mu Jiu said with a smile. "Didn't we discuss this?"

"yes. Xie Yu paced back and forth in the room, walking and stopping, as if he was groping for something.

"Does this have anything to do with the purpose of those people wearing masks?" There are huge secrets hidden in the Secrets, and if we know what is written in the Secrets, we can know the conspiracy behind them, right?"

"Well, you're right. Xie Yu finally stopped his pace and nodded at Gong Mu Jiu.

"Brother Ziqi, do you know what is included in the "Secrets"?" Gong Yi Mu Jiu asked Xie Yu, looking a little anxious. "Can you know where the "Secret" is? We should find a way to remind my father that there are ghosts in the house who steal books!"

"I don't know. Xie Yu shook his head, pointed at Gong Mu Jiu and said, "But I found the inner ghost." ”

"Brother Ziqi... You... Don't slander me. Gong Mu Jiu looked at Xie Yu with wide eyes and surprise, and he could stuff an egg in his mouth.

"Don't be so nervous. Xie Yu replaced his serious expression and smiled at Gong Mu Jiu.

Gong Mu Jiu immediately breathed a sigh of relief after hearing this, patted his chest gently, and was just about to speak to ridicule Xie Yu, but unexpectedly, the vision rose sharply... He felt a throbbing pain in his chest, and he couldn't help but scratch it with his hand to try to relieve it. But when his hand touched his chest, he realized that the pain came from his heart. The pain came in waves, like waves in the water hitting his heart chambers layer by layer. Gong Yi Mu Jiu squatted down in pain, and yelled with hideous facial features: "Brother Ziqi, what did you do?!"

"Hmph. Xie Yu snorted coldly, and Gu Zi walked to the bottom of the crack on the wall. "How long are you going to load?"

"How did you know?" Seeing that his identity had been revealed, his left hand quickly sealed the veins on his chest, and then stood up and looked directly at Xie Yu, his eyes under the shadow were full of doubts.

"It starts with your pretentious and exaggerated acting. Xie Yu didn't look back, just looked at the slit.

"Oh? contemptible people have been practicing the art of transfiguration since childhood, and nine times out of ten, others can learn it just by chatting once, and their tone and demeanor will not be wrong, why is it an exaggeration of acting skills?"

'Gong Yi Mu Jiu' laughed, and his words were full of doubts and playfulness.

"There you go. Xie Yu's eyes lit up, and he tapped the wall with his hand, completely ignoring the other party.

"Look for death!" Seeing that Xie Yu did not put himself in his eyes, he was annoyed in his heart, and rushed towards Xie Yu without saying anything, but found that he could not move in the slightest.

"What did you do!" 'Gong Yi Mu Jiu' roared at Xie Yu.

"'Qingtian' has no one told you about the Wuqi Mathematics Technique?" Xie Yu turned his head and looked at 'Gong Yi Mu Jiu' suspiciously.

"Five Qi Numbers?" 'Gong Yi Mu Jiu' muttered, as if trying to search for this strange and unfamiliar term in his memory.

"Don't say anything, I'm going to say goodbye. Xie Yu turned around and faced the wall again. "Remember to tell your leader, this time it was Yu who confessed, if you want "Wood Machine", don't hurt Gong Mu Jiu. ”

After that, the wall collapsed, and the crack at the top was torn wide, just enough for one person. Xie Yu jumped up from the entrance of the cave with both legs, and 'Gong Yi Mu Jiu' looked shocked as he looked at the exaggerated collapse of the wall.

"Oh yes, I advise you to unseal the acupuncture path, otherwise you won't be able to support your accomplices to save you. ”

The quieter the voice, the more indistinct it became.
