The upright dragon head standing in the pool is like a pillar in the middle. There is no door at the bottom and no window at the upper floor. The white-fly elite soldier shot out the dragon claws, climbed up the dragon's mouth that opened diagonally upwards, and drilled into the hidden drainage hole. This hole is the mystery hidden in the Jieying Cup. As long as the water overflows this hole, the water in the pool will pour out.

Not long after, Dian Wei, covered in blood, walked out of Long's mouth again and waved to Su Yue far away.

Seeing the bronze beast head on the four walls of the pool, it no longer came out of the water. Su Yue was overjoyed: "Things are done!"

Immediately, I went downstairs and arrived at the upright dragon head. Dian Wei tied it to the dragon mouth with a rope. The two of them were one in front and one behind, and there was a drainage hole in the mouth, and they bent their waists into the inside. They climbed up the ladder and entered the top pavilion.

The eyes lit up, there was a different world.

Because of the fact that the hangover was in the water, the upright dragon head could not store a lot of air, so there were not many people inside. Apart from the two yellow turban guards who were broken, there were only two craftsmen and one old Taoist. There were only five people in the entire "cardinal".

The old Taoist is so fairy-like and sits upright in the middle. A "seven-string sounding device" used for slogans is hanging in front of him. After a closer look, the old Taoist is gloomy and has a look of being out of the world. Unfortunately, he is bleeding from the corner of his mouth at this time, and his breath is like a wandering silk. Obviously, he is not allowed to do anything, so he committed suicide by taking poison. If Zhang Chun is not dead, he will definitely recognize this person. He is the Taiping Immortal Master who bewitched him with troops to rebel.

Su Yue approached and bowed with a solemn look.

The old Taoist expression changed slightly, and he spoke hard: "How can I know?"

"I am just a disciple of the Mo Sect." Su Yue bowed and replied. When he bowed, his four fingers crossed and his thumbs were incorrect, which was Mo Li.

"Okay, okay, okay..." The voice gradually became unheard. The Taiping Immortal Master who went astray had already left.

Then Bai Liwei reached out to visit: "The person is already exhausted."

Su Yue then slowly stood up: "Don't be careless."

"Yes." Dian Wei focused heavily.

Su Yue turned around and rushed to the two young craftsmen who were crawling and kneeling on the ground, trembling, and asked softly: "Why are you here?"

Then a man cried and said, "Just to open and close the valve."

"Why do you need two?" Su Yue asked again.

"There are two valves: ventilation and water loss. Therefore, I need two brothers." The man said again.

"Let's talk about it." Su Yue nodded.

"The water-relieving valve is hidden in the dragon's mouth. As long as the water is full, open this valve and the water accumulated in the pool will be poured out." After swallowing, he continued: "The air-relieving valve is hidden under the dragon scales. Just need the dragon's head to come out of water and open this valve to let the new air inject and rinse the turbid air."

No wonder it can hide the entire dragon head in the water. There is a valve inside the dragon mouth where the drainage hole is hidden, which can be manually controlled to open and close.

That is to say, it was not before that the water was pushed into the warehouse building, or even the water flowed out. It was by chance that the gate just opened.

Fortunately, luck!

Think about it, too. How can such an exquisite mechanism design leave such a huge loophole?

Su Yue was able to reach here without any obstacles. It can only be said that the ancestors were blessed by the Yellow Turbans.

The reason why the five people in the inner room is that they still have a hole to ventilate. As long as the air exchange valve is opened, the water stop valve buried in the four walls of the pool will be closed at the same time. No longer inject water into the pool. Another function of ventilation is naturally to transmit sound. Otherwise, how can the sound be transmitted in the confined space?

Su Yue has seen the water-insulation valve in the dragon's mouth, which is forged with Jiguo's check valve technology.

All signs indicate that Ji Guo will definitely have nothing to do with the Yellow Turban Thief.

When Su Yue thought of this, he couldn't help but sigh. He said, "I'll ask the captain to take care of the two of them well. I'll interrogate them carefully after the battle."

Dian Wei immediately ordered Bai Li to take down the two of them. He asked again: "What should we do now?"

Su Yue rushed to the "Seven-string utensil" hanging in front of Taiping Immortal Master, saying, "Now the 'cardinal' has fallen into my hands. I should help the Han army with one arm."

Dian Wei then realized: "Does the Ming court want to play this chess?"

"Yes." Su Yue bowed forward again, stepped on the couch and slowly lifted his body. He was afraid that the Taiping Immortal Master would hide his mechanism when he was ascending to the immortals. Seeing that there was nothing unusual, he landed his feet on the ground and sat in front of the old Taoist.

The erect dragon head is briefly released from the water to control the chess game. Obviously, the old Taoist is a master of blind chess. The changes in the chess game are in my heart. Su Yue is not inferior. After thinking about it for a moment, he took off the old Taoist finger and put it on his finger.

Yijia is the fake nail used to pluck the piano, also known as "bone claw".

"Play the zither with more than a tiny inch of the bones and claws to replace the fingers."

The string sounded throughout the sky.

In the city, many units of the Han army were surrounded and intercepted, with heavy springs, arrows flying like rain, and many mechanisms that sprayed flames, poisonous smoke... as if they were contagious, stopped attacking one after another, and slowly retreated, revealing a path.

"General!" The captain, covered in smoke and fire, was still in shock.

Looking at the Yecheng District at the end of the road, Huangfu Song made a quick decision: "Run into the district and capture the commander Qu alive!"

"Be careful of fraud!" Then the captain came forward and made a comment.

Huangfu Song pointed to the dead street and angrily said, "It must be a good craftsman in Ji Kingdom who can see through the secrets of heaven. Otherwise, how could the Yellow Turban Thief be distracted and reveal the place of the camp. Don't doubt it, just kill me!"

"kill--"

Previously, the mechanisms and instruments were laid down one after another, and the Han army had been divided into several sections. The situation was very good, and the victory was in sight. For some reason, they retreated like a tide. In the blink of an eye, all the great roads opened up east, west, south and north.

The Yellow Turban soldiers in the gatehouse looked as if dead. "No, no! The Han army has broken the formation of the organs--"

"Report——" In the camp in the southeast of Yecheng, there were a knights of Yisanhe who rushed in with a fast horse.

"General Zuo Zhonglang attacked the county seat of Yecheng. Please help the general to provide a quick reinforcement!"

The captive general Tian Yan stood up excitedly: "All the generals obey the order!"

"exist!"

"Beat the drum to fight and reinforce the Left Central Army General!"

"Here!"

Hearing the sound of drums outside the city, killing sounds were everywhere. Su Yue stood up, bowed to Taiping Immortal Master again, and slowly retreated to the bed.

Seeing that the battle was settled, Dian Wei returned excitedly. Seeing Su Yue's move, he couldn't help but ask, "Why should Mingting treat a dead person so much? It's so polite."

Su Yue wiped away the cold sweat from his forehead and then replied: "'Mo people will not attack each other'. Mo people must set up a mechanism under him to destroy themselves. The reason why he died was that he knew that I was also a student of the Mo family, so he showed mercy."

"So that's it." Dian Wei then stepped forward with a solemn look and saluted the old man respectfully.

Su Yue turned around and said to the two young craftsmen: "You two are also Mozhes."

The boy who had previously shrank into a ball was completely scared when he heard the sound. He nodded slightly: "That's it."

"Can you follow me in the future?"

Both young men shook their heads: "We should go after our ancestors. Sir, leave quickly. I am afraid that our teacher will be unable to chase after us."

Dian Wei was stunned. The reason why the second young man hid his identity was that he wanted everyone and the old Taoist to be buried with him!

Seeing that Su Yue was polite and polite from beginning to end, he not only revealed the hidden mechanisms under the old Taoist body, but also said that "Mo people do not attack each other". He then confirmed that Su Yue was indeed a student of the Mo family. Only then did he know his identity and let everyone go!

Very dangerous.

Su Yue treated him with ink courtesy.

The two returned with ink ceremony.

Everyone fell down from the dragon's head in a row. In a moment, thick smoke came out of the dragon's mouth, and a fire immediately ignited. After a day and a night, the cardinal was burned to ashes. There was no trace to be found.

By the way, without the piano sound scheduling, many mechanisms and instruments have no heads.

The formation of the organs was broken, and the stronghold in Yecheng, which the Yellow Turban thieves worked hard, was also broken by the Han army.

The bandits panicked and abandoned the city and fled. All the Yellow Turban senior officials in the capital were killed.

Three days later, the remnants of the Yellow Turbans in the city were wiped out.
