The upright dragon head standing in the pool is like a mainstay. There are no doors at the bottom and no windows on the upper floors. The white elf shot out the dragon's claws, climbed all the way up the dragon's mouth that opened diagonally upward, and drilled through the hidden drainage hole. This hole is where the hidden mystery of the ring cup lies. As soon as the water overflows the hole, the pool will be empty.

Not long after, Dian Wei, who was covered in blood, walked out of the dragon's mouth again and waved at Su Yue from afar.

Seeing the bronze beast heads on the four walls of the pool, they no longer come out of the water. Su Yue was overjoyed: "It's done!" ”

He immediately went downstairs and waded to the head of the upright dragon. He was tied to the dragon's mouth with a rope by Dian Wei. The two of them went one after the other, hiding drainage holes along the mouth, and bowed their waists inside. Climb another section of the upward hanging stairs and enter the top pavilion.

The eyes are bright, and there is no cave.

Due to the fact that the upright dragon head cannot store a large amount of air in the water, there are not many people inside. Except for the two yellow turban guards who were smashed, there were only two craftsmen left, and Lao Dao was alone. In the entire "cardinal", there are only five people.

The old fairy wind bone, sitting in the middle. In front of him hangs a "seven-string articulation device" for communication. Under a closer look, the old road fluttered out of the dust, but it was a pity that the corners of his mouth were bleeding at this time, and he was angry. Obviously, he couldn't do anything, so he committed suicide by taking poison. If Zhang Chun hadn't died, he would have recognized this person. It was the Taiping Immortal Master who tricked him into raising troops to rebel.

Su Yue stepped forward and bowed solemnly.

Lao Dao's expression changed slightly, and he said with difficulty: "How do you know?" ”

"It's just below, and it's also a disciple of Momen." Su Yue bowed and replied. When the fingers are crossed, and the thumbs are wronged, it is a motif.

"Good, good, good......" The sound faded into obscurity. The Taiping Immortal Master, who has gone astray, has gone west.

Then Bai Yuwei stretched out his hand to visit: "People are already angry." ”

Su Yue slowly got up at this time: "Don't be scornful." ”

"Hmm." Dian Wei nodded heavily.

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

One of them cried, "Just to open and close the valve." ”

"Why two?" Su Yue asked again.

"There are two valves: ventilation and water control. That's why I need two brothers. The man said again.

"Say it." Su Yue nodded.

"The water valve, hidden in the dragon's mouth. As soon as the water is full, open the valve and the pond will be empty. Swallowing his saliva, he continued: "The ventilation valve, hidden under the dragon scales, only needs the dragon's head to come out of the water, open this valve, you can let the fresh air in, flush out the turbidity." ”

No wonder the entire dragon's head can be submerged in water. There is a valve in the dragon's mouth with hidden drainage holes, which can be opened and closed manually.

That is to say. In the past, it was not pushed into the water, or even full of water flowing out. It was a coincidence that the floodgates just opened.

Thankfully, fortunately!

Think about it too. How could such a brilliant mechanism design leave such a huge loophole?

Su Yue was able to get here all the way unimpeded. It can only be said that the ancestors blessed it, but the yellow scarf of the death of the sky.

And the reason why the five people in the secret room are not dead is because they also set up holes for ventilation. And as long as the ventilation valve is opened, the water stop valve buried in the four walls of the pool will also be closed at the same time. No more water is poured into the pool. Another function of ventilation is, of course, for sound transmission. Otherwise, how can the sound come out of a confined space.

Su Yue has seen the water-proof valve in the dragon's mouth, which is forged with the check valve technology of the Thistle Kingdom.

By all indications. The thistle country will be inseparable from the Yellow Turban thief.

Thinking of this, Su Yue couldn't help but sigh. Then he said: "The captain of the school is tired of taking care of the two good students. After the war, we will interrogate them in detail. ”

Dian Wei immediately ordered Bai Yu to take down the two. Then he asked, "What should we do now?" ”

Su Yue said to the "seven-stringed instrument" hanging in front of the Taiping Immortal Master: "Now the 'cardinal' has fallen into my hands. Since he should help the Han army. ”

Dian Wei then woke up: "Ming Court wants to play this chess!" ”

"Yes, yes." Su Yue bowed forward again, stepped lightly on the couch, and slowly lifted his body. I am afraid that the place where the Taiping Immortal Master will feather and ascend to the immortal will hide the mechanism. Seeing that there was nothing abnormal, he landed on his feet and sat down in front of Lao Dao.

The upright dragon's head briefly comes out of the water, and the chess game can be controlled. Obviously, Lao Dao is a master of blind chess. The changes in the chess game are all in the heart. Su Yue is not far behind. After a little recollection, he took off the prosthetic nail on the old Taoist finger and put it on his finger.

The prosthetic nail is the false nail used in the piano, also known as the "bone claw".

"Playing the kite with bone claws is more than an inch, in order to refer to it."

The sound of strings fills the sky.

In the city, the Han army was surrounded and intercepted, and the machine spring was great, the arrows were like rain, and there were many spray flames and poisonous smoke...... of the trap. As if contagious, it stopped attacking one after another, and then slowly retreated, revealing a pathway.

"General!" A captain covered in smoke and fire and with a disfigured face was shocked.

Looking at the Yecheng Governance Office at the end of the road, Huangfu Song immediately decided: "Rush into the governance office and capture Qu Shuai alive!" ”

"Beware of deception!" Then the captain stepped forward to speak.

Huangfu Song pointed to a dead street, and said angrily: "It must be a good craftsman of the Ji Country, peeking through the heavens." Otherwise, how could the Yellow Turban thieves mess up and reveal where the camp is. Don't be suspicious, let me kill you! ”

"Kill—"

Previously, the traps were set up layer by layer, which had divided the Han army into several sections. The situation is very good, and a big victory is in sight. For some reason, they receded like a tidal wave. In the blink of an eye, all avenues are unblocked, east, west, north and south.

The yellow scarf in the watchtower of the governance office is like ashes. "Oh no, no! The Han army has broken through the great array—"

"Newspaper-" In the southeast camp of Yecheng, there were three river knights, and the horses rushed in.

"Zuo Zhonglang will attack Yecheng County, please send reinforcements to the general quickly!"

The captive general Tian Yan got up angrily: "The generals listen to the order!" ”

"In!"

"Beat the drums and go out to reinforce General Zuo Zhonglang!"

"Whoa!"

Hearing the rumbling of drums outside the city, the sound of killing was everywhere. Su Yue got up, bowed to the Taiping Immortal Master again, and slowly retreated.

Seeing that the battle situation had been decided, Dian Wei returned in a hurry. Seeing Su Yue's move, he couldn't help but smile and asked: "Why does Ming Court need to be so polite to a dead person." ”

Su Yue wiped away the cold sweat on his forehead, and then replied: "'The ink does not attack'." Under the ink man, there must be a mechanism to self-destruct. The reason why I died was because I knew that I was also a disciple of Momen, so I showed mercy. ”

"I see." Dian Wei stepped forward solemnly and saluted respectfully to the old man.

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

The young man who was still shrunk into a ball before was instantly fearless when he heard the sound. Nodding slightly: "Exactly." ”

"Will you follow me in the future?"

The two teenagers shook their heads: "I'll wait for me to chase after the first teacher, and the gentleman will leave quickly, I'm afraid that my master will go away, and it will be difficult to chase after me." ”

Dian Wei was dumbfounded. The reason why the second young man hid his identity was to make everyone and the old man be martyred!

Seeing Su Yue from beginning to end, he was polite and courteous. Not only is there a hidden mechanism under the old Dao, but he also says 'the ink does not attack each other'. It was determined that Su Yue was indeed a disciple of Momen. Only then did he reveal his identity and let everyone go!

It's dangerous.

Su Yue treated each other with ink courtesy.

The two returned with ink gifts.

The crowd fell from the dragon's head. Suddenly, smoke rose from the dragon's mouth, and a fire immediately ignited. After a day and a night, the cardinal was burned to ashes. No trace was found.

Saying. The piano sound scheduling is lost, and many organs are leaderless.

The large array of organs was broken, and the Yecheng stronghold that the Yellow Turban thieves painstakingly operated was also broken by the Han army.

The thieves panicked and abandoned the city and fled. And the high-level yellow turbans in the governance center were all punished.

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

Yecheng was then recovered.
