In the early morning of the next day, there was a gentle knock on the door of the guest house.

"Door, smell also". "One door, two doors. It is also in the east of the hall and the door in the residential area. ”

"Who's outside the door?" It is the son of Rongli.

"Contemptible Guo Jia, does the son get up?"

"Wait." Rongli Gongzi sorted out his clothes, and then opened the door to greet him.

"I've seen Childe." Guo Jia smiled.

"I've seen the master book." Rong Li was slightly flustered: "Please speak in Shene." ”

"Please."

The guest and the host sat down, and Guo Jia sniffed lightly: "The sachet carried by the son is very peculiar. Can I give away the formula? ”

Rong Li's face was slightly red: "There is no sachet, but my body fragrance." ”

"Forgive sins, forgive sins." Guo Jia hurriedly apologized. A smile appeared in his eyes.

"It doesn't matter." Rong Li hurriedly covered up: "Those who don't know are not guilty." ”

"Gongzi is proficient in Chinese, but it is very different from the Wuxi native accent. Is it from somewhere else? Guo Jia also did not pursue it.

"I'm not from the Wuxi tribe, I'm from the Yulin Xiou (ōu) clan." Rong Li told the truth.

"I see." Guo Jia nodded lightly: "Since you are from Jiaozhou, why are you stranded in Wuxi?" ”

"The family has changed, and the disaster has come to this." Rong Li replied casually.

Guo Jia did not pursue it. So Dao Ming's intentions: "The imperial court will reopen Hengshui Duwei, and in the near future, it will be the territorial sea city, go against the water, and exchange markets with Wuxi." Childe has been here for a long time, can you tell me the waterway, details. ”

After taking a deep look at Guo Jia, Rong Li said: "Yuanling (County), the mountains are rugged, the water is fierce, and there are more beach dangers. In particular, Yuanshui is close to Yuanling, Qinglang, Hengshi, Jiuji, Bairong, etc., and the dangerous shoals are one after another. And the clear waves are the most dangerous. It is known for being 'shallow, dangerous, urgent, narrow and curved'. The long beach is more than 50 miles away, and it is also a thousand miles of water, and it is the longest one among the more than 100 beaches. It only takes a moment to go down the river, but it takes a whole day to sail against the current. ”

Seeing that Guo Jia was noncommittal, Rong Li said again: "When General Fubo came to the aid of the horse, when the reverse water arrived at Qinglang Beach, the army was trapped in Hutou Mountain on the south bank, and it was difficult to advance an inch. He once sighed and said, 'The surging Wuling River is deep, and the birds do not fly, and the beasts do not come'. Even if the Wuxi people cross this place, they also need to get off the boat and walk, and wait until they have passed the Qinglang Beach before boarding the boat and moving forward. When you go to Jiuji, Hengshi and other beaches, you still need to use the shore wrestler to pull the boat before you can cross the beach. ”

"I see." Guo Jia bowed his head slightly: "It's as big as the Youlin, can you cross?" ”

"Absolutely not." Rong Li shook her head categorically.

Seeing Guo Jia's suspicious face, he didn't seem to believe it. Rong Li said again: "When I came before, I saw a 'strange stone' on the mountain rocks on both sides. Densely covered with holes, like honeycombs. Wuxi people call it 'honeycomb rock'. I asked Fang Zhi, but it is not natural. The honeycomb on the stone is the 'penny eye' of countless boatmen and boatmen in Wuxi, when they support the penny. When you fly down the river and are about to hit the reef head-on, you will be covered with iron and penny, and you will be able to support it. Iron and stone hit each other, the spark is not exhausted, and it has gone ten miles. After a little hesitation, the ship was wrecked and people died. ”

"In other words, if you cross the water, you will remove the underwater reef."

"This ......" Rong Li said hesitantly, "the water is fierce, and there is no way to anchor." Whenever a craftsman enters the water, he is swept away by the turbulence. How to remove reefs. ”

"Childe wants to know the details, why don't you take a look?" Guo Jia pretended to be mysterious.

"That's fine." Rong Li nodded slightly.

Then he called Shang Shamoke and the others to go together.

The lower reaches of the Yuanshui River are open, which is conducive to boating. Then when you arrive at Hutou Mountain, you will encounter a dangerous beach. In the twenty-fourth year of Jianwu, General Fubo came to the aid of horses, and led troops here, because of the high mountains and dangerous beaches, the army was trapped under the mountain, and it was difficult to advance an inch. When the weather was hot, many soldiers died of illness, Ma Yuan ordered his subordinates to dig stones for the room to escape the heat, according to legend, a total of 48 rooms, which can accommodate several seats.

Taking the Youlin, and the large and small boats, against the Yuanshui, Shamoke and others stood on the deck, and there were many discussions: "I heard that the king once 'went down to argue and remove stones' to solve the local floods. There is no other way, and I don't know. ”

"Qinglang Beach is full of reefs, like stone forests in the water. And the water flow is fierce, and it pours for hundreds of miles. There is no anchor, and there is no place to stand, so there are skilled craftsmen, how to do it? But Shamoko did not believe it.

"There is a ship of the thistle country in front of it, which goes against the water. But I don't know if it can be related to today's events. Someone else said.

"Why bother, just look at it." Shamoko waved his hand.

With doubts, after several days of sailing, everyone finally arrived at Hutou Mountain.

"This is ......" Everyone on the deck was already stunned.

I saw that on the waterfront rock of Hutou Mountain, a row of hanging buildings was built out of thin air. It's like a plank road, hanging on the mountain rock. On the other side of Hutou Mountain, there were also several machine boats, which ran aground on the shore in formation. Several suspension cables, through the suspension tower and the ship's crane arm, across the water.

There are also some strangely shaped machine boats, which are being dragged by suspension cables, moored in the rapids in the middle of the river. The machine boat is roughly in the shape of a lying "work". for catamarans. Between the two ships, the beam is flying, and the beam is slotted with a cast iron hammer. The conical hammer head is pointed straight at the surface of the water. The hammer can be transmitted by a gear, and in the groove rail, it can be moved left and right and up and down.

"What is this?" Seeing that his companion had opened his mouth wide in shock, Rong Li asked.

"This boat is commonly known as 'I-boat', also known as 'Yugong boat'. Because of the bridge frame on the ship, it is named after the 'foolish hammer' hanging on it. Guo Jiayan said: "Yugong hammer, borrow the ship to lift the engine, the faster the current, the more advantageous it is to borrow strength." In addition, there are underwater steel cables connected to the animal turbines in the suspended building. Hydraulic, accumulating, and lifting at the same time. When the hammer reaches the top, it will fall on its own and hit the reef hard. And so on and so forth. Until ......"

Before the words fell, under the continuous heavy blow, a reef collapsed. Carried away by the torrent, there are no bones left. Because of the force, it runs through the entire reef from top to bottom. It will not stop the waist from breaking. When the principle class was constructed, Liu Bei personally designed it as a rammer for ramming piles.

"What if it's an underwater reef?" Rong Li asked again.

Guo Jia pointed to a Yugong boat under construction and said: "First nail a 'Yugong nail' into the reef, lead the nail cap out of the water, and then hit it hard." ”

"Why can the Yugong ship be anchored in the torrent?" Shamoko asked.

"It's a Hengjiang steel cable traction." Guo Jia pointed to both sides of the water, the hanging tower of Hutou Mountain and the stranded machine ship on the opposite bank.

"How can a machine boat sit on the shore?" Shamoko asked again.

"The bottom of the ship is watertight, and there is a secret door next to it. When the floodgates are opened, water from the river is poured in. The machine sank and ran aground. The water was drained, and the boat floated out of trouble. Lift and fall freely. Guo Jia replied again.

"I see." Rong Li suddenly woke up. In a word, artificially controlled shipwrecks.

Guo Jia said with a smile: "It is dangerous here, so we will build a hanging building first to support it." In general, it is necessary to set up two columns of 'hundred-footed boats' to sit on the beach. You can pull the steel cable horizontally, pull the Yugong boat to the center of the turbulent current, and smash the reef. ”

"What is a hundred-legged boat?" Shamoko asked.

"With several, or even dozens, of them were transformed by land and water with 'siege boats', and the light boats were connected in series. It is shaped like a hundred-legged insect (horse worm), hence the name. Guo Jiazhi said: "You can swim near the shallow water or the shallow shore beach, and then release the water to sit on the beach." ”

"A hundred dangerous shoals, how long do you need to hammer them?" Shamoko pouted.

"Hundreds of dangerous shoals, at the same time. It is expected that it will not be long. "Guo Jiafeng is light.

"Goo-dong!" The crowd was amazed.

The machine of the thistle country is so terrifying!
