On the way, Gao Yue saw Xuanrun's masters' riding skills. They could master hard sails and soft sails skillfully, and they could add sails to deal with all wind directions flexibly and avoid various risks with ease. Gao Yue also saw Xuanrun's masters tied up a row of giant bamboos on both sides of the ship's side, which made the ship sail more smoothly and smoothly in the vast Han River.

At this time, under the boat shed, Master Mingxuan was calm and composed. He was sitting on the boat board, and kept holding Li Daoyuan's "Water Classic Notes" in his hand, recording the hydrological geography along the Han River coast, and the two references were made.

Li Jie was born in the Central Plains, so he was quite adept. However, Gao Gu and Guo Zaizhen were miserable because they were both northerners and had been in the army in Shuofang area for a long time. They were not used to boating in the wind and waves. "Why, why do you ask me to come!" Guo Zaizhen simply lay softly on the boat, unable to tell the difference between the north, west and south.

At this time, Gao Yue looked at him and thought that there is a reason to call you here.

At the mouth of the river where the Jia River and the Han River of Shangjin Fort meet, Qianhu ships were placed under Dading and tied to the shore. The official of Shangjin Transportation Envoy Wanqi, the governor of Junzhou, Wu Xianfu, the commander of Shannan military commander, and a group of local officials stood on the shore to welcome the arrival of Gao Shaoyin.

Especially Wu Xianfu, when he saw Guo Zaizhen rolling his eyes when he got off the boat, he was even more overjoyed and asked if Wei Guo still remembers me, I am the Xianfu who worships and gives you a sword in Xingyuan Mansion!

Since Guo Zaizhen is here and Wu Xianfu is here, the following things are easy to deal with - Wu Xianfu immediately brought 300 soldiers from Manchuan Pass, cooperated with the craftsmen brought by Gao Yue to install a starting rod at the stern of the four thousand-hu boats.

The so-called stick is a weapon for water war, and its prototype is an orange steak used to draw water in rural areas in ancient China.

The sticks required by Mingxuan and Gao Yue are a relatively simple type, namely the sticks with "t" characters:

A large wood is erected at the stern of the boat. It is a vertical rod. The top of the vertical rod is installed, and a horizontal rod is installed. The horizontal and vertical bar is exactly in the shape of a "t" shape. The horizontal bar can be moved up and downward in axial direction. The top of the crossbar is tied with a stone, and then a rope is tied to the tail end of the crossbar. Usually, it is twisted with a wheel on the deck. Once it approaches the enemy ship, the wheel is released, and the top of the crossbar falls rapidly under the gravity of the stone, slaps and destroys the enemy ship. This is a "bang rod".

But what Gao Yue wants to tie on the pole is not a stone.

A few days later, Yunxiang leaned against the shore of the Han River, Gao Yue held the drawings in his hand, and with the company of everyone, he finally saw the so-called "Yunxiang Ertan."

"These two beaches are called Lao, Jing Ertan." Wu Xianfu on the shore pointed to a huge rock in the turbulent flow and said, "This is Baitan. When the water is shallow in winter, it will appear like a mountain, isolating the big ships from coming and going. If you touch it, even if you have a thousand-hu boat, the ship will inevitably be destroyed."

Then, Wu Xianfu pointed to a rapid turbulent flow further east, "This is called a clean beach. After the summer water rises, the water flows too fast, and travels are painful. It often carries a small boat and rushes to the big rocks of the watery beach, and all of them are made of powder."

Finally, Wu Xianfu put his waist on his back, sighed, and said to Gao Yue: "Therefore, there is a song in the territory of Junzhou that says that in winter, the mission of cleansing in summer is to be cut off."

Even officials dare not pass by Ershitan, and the rest of the merchants can be imagined.

My aunt and Yun and their team also took a big boat to land in Yunxiang first, and then hired a small boat in the Transportation Courtyard to pass the Jiashui River, then enter the Hanshui River, and all the way through Jinzhou and Yangzhou to Xingyuan Prefecture.

Before leaving, Yunhe also found Gao Yue specifically. When she was in the transfer yard, she saw a small boat with her own eyes. When she passed the clean beach, the water flowed too fast, rushed to the huge rock on the beach. When several oarists were shattered, they held the last bit of hope and stretched out the long pole, trying to hold on to the huge rock and spread the boat open, but what they answered was a terrifying loud noise. When Yunhe saw that the oars and the boat bent on the huge rock together, they disintegrated. The group of oars and the oars who fell into the water were all involved in the ups and downs and disappeared without a trace.

So when Yunhe talked about this, his face turned pale.

The fact that Han Huan's four thousand-hu boats were able to successfully arrive at Xingyuan Mansion was definitely due to excellent technology.

"I told him not to be able to do anyone's mission in the future!" Gao Yue pointed to the huge rock in the beach and said loudly, "I will destroy this evil soon."

"How can this big stone be destroyed?" Guo Zaizhen was very surprised.

"Iron and fire can overcome huge rocks." Gao Yue immediately said the solution.

In the torrent, two thousand-hu boats with pole-pats were connected by iron ropes. Then Zhang Xi stood on the rudder shed, waved the red flag, and shouted: "Get the bamboo bundle!"

"Here!" Xuan Run's crossbowman, the oar master shouted in unison, and his voice overwhelmed the sound of the collision between the Han River and the huge rocks on the beach.

Then, the large bamboo produced in Yangzhou was fluttered and put down the noose and sank into the water, making the Qianhu boat more stable in the turbulent flow.

"Go to Dazhong!" Zhang Xi shouted again.

The Dakuen on the ship went down the winch and fell into the river. The ship immediately arrived at the huge rocks on the watery beach like Mount Tai. The water stormed the ship frantically, making a terrifying sound of war drums.

"Downstream Ice!"

The small anchor stone on the side of the ship was also thrown down to prevent the ship from shaking.

"Burning a fire!"

"Here!"

The craftsmen then hung a large iron basin with four outstretched wooden poles under the stern of the boat, filled with fine charcoal. The craftsmen stretched out long bamboo poles that burned flames. The brazier lit the fire, and the flames rose.

The craftsmen then relaxed the wheels, and the crossbar was tied to the reef-breaking instrument forged in the Chenggu Iron Official Workshop - a thick and sharp iron cone of more than meter.

The large iron cone penetrated into the brazier along the top of the horizontal bar, and then the blue smoke continued to rise, and the craftsmen on the boat looked at it intently until it burned red.

"Closing the brazier and twisting the wheels!" With Zhang Xi's order on the helm shed.

The brazier was retracted with a long pole, while the ropes on the wheel were strangled one by one, and the crossbar hanging with the big red iron cone gradually raised, and then raised it, hanging on the top of the huge rocks on the beach.

"put!"

With the rapid rotation of the wheel, the iron cone also fell heavily. With a loud bang, it hit the protruding part of the boulder, and quickly smashed several cracks, and the high temperature of the cone also wedged into the gap, and a few blue-white smoke came out of the stone.

The craftsmen and crossbowmen immediately cheered.

Then the rod kept lifting the iron cone and then patted it heavily.

The half of the huge rock gradually could not stand it, it became more and more broken, and the cracks became more and more obvious. The water began to rush around, wrapping smaller stones, rolling and rushing towards everywhere, and the large stones slowly collapsed and slid down.

"Oh oh oh oh!" On the shore, Wu Xianfu, Guo Zaizhen, Gao Gu, Wan Qi, and waited for the county magistrates, county magistrates and county magistrates of Yun Township, all of them made both excited and incredible surprises.

Soon, the Qianhu boat that had smashed the huge rocks on the beach and split up the split was set up, turned the wild fox sail, and slowly retreated.

Two other thousand-hu boats took over, and solid iron balls hung on their rods.

The iron ball kept falling, completely smashing the rock.

The originally arrogant huge rocks disappeared in less than a day!
Chapter completed!
