On the way, Gao Yue can be regarded as seeing Xuanrun's penny masters riding the wind and waves, they can skillfully control hard and soft sails, and will also add sails, flexibly respond to the eight wind directions, and avoid various risks with ease, Gao Yue also saw that Xuanrun's penny masters will tie a row of giant bamboos on both sides of the ship, which makes the boat sail more smoothly in the mighty Han water.

At this time, under the shed, Master Ming Xuan was calm, hovering and sitting on the board, and constantly lifting the pen, while holding Li Daoyuan's "Notes on the Book of Water", recording the hydrogeography along the Han River, and the two references.

Li Jian is from the Central Plains, so he is quite passable. However, Gao Gu and Guo Zaizhen were miserable, because they were both from the Northland, and they had been in the army in the Shuofang area for a long time, and they were not used to sailing in the wind and waves, "Why, why is it called me!" Guo Zaizhen simply lay on the boat softly, a little unable to distinguish between north and south, east and west.

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

At the mouth of the confluence of Shangjin Fort Jiashui and Han Shui, Qianhu boat went down to the big pier, tied to the shore, the right to know the Shangjin transfer envoy Wan Qian, Junzhou Thorn History, Shannan soldiers and horses Wu Xianfu, and a cadre of local officials, have stood on the shore to welcome the arrival of Gao Shaoyin.

Especially Wu Xianfu, when he saw Guo Zaizhen who rolled his eyes when he got off the boat, he was even more overjoyed, so he asked Guo Duwei if he still remembered me, I am the one who gave you a sword at the altar of worship in Xingyuan Mansion!

Since Guo Zaizhen is here and Wu Xianfu is also here, the following things are very easy to do - Wu Xianfu immediately brought three hundred soldiers from Manchuan Pass, and cooperated with the craftsmen brought by Gao Yue to install the clap rod at the stern of the four Qianhu boats.

The so-called slap pole is a weapon of water warfare, and its prototype is the orange tree used to draw water in the ancient countryside of the Celestial Empire.

The clapper pole required by Ming Xuan and Gao Yue is a relatively simple type, that is, the "T" shaped clap pole:

Erect a big log at the stern of the ship, it is for the vertical rod, the top of the vertical rod is equipped with a mechanism, and then install a crossbar, the horizontal and vertical is just in the shape of "T", in which the crossbar can do axial movement up and down, the top of the crossbar is tied to the stone, and then the tail end of the crossbar is tied to the rope, and the reel on the deck is twisted and put away on weekdays, once it is close to the enemy ship, the reel is released, and the top of the crossbar falls rapidly under the gravitational action of the stone, and the blow destroys the enemy ship, which is the "slap rod".

But what Gao Yue wants to tie to the clapper stick is not a stone.

A few days later, Yunxiang leaned on 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 waterlogging and clean two beaches." Wu Xianfu, who was on the shore, pointed to a boulder in the turbulence and said, "This is the waterlogged beach, when the water is shallow in winter, it will be exposed like a mountain, isolating the big boats from coming and going. ”

Subsequently, Wu Xianfu pointed to a rapid turbulence further east, "This is called a clean beach, after the summer water rises, the water flow is too turbulent, and the travel is hard, often carrying a small boat, rushing to the big rock of the waterlogged beach, all of which are powder." ”

In the end, Wu Xianfu crossed his waist, sighed, and said to Gao Yue: "Therefore, there is a song in the boundary of Junzhou that says that the winter is flooded and the summer is clean, and the official mission is broken. ”

Even the officials did not dare to pass by on this two rocky beaches, and the rest of the businessmen could be imagined.

Aunt Niang and Yun and their party also took a big boat to land in Yunxiang first, and then hired a small boat in the transfer yard with a handful, crossed Jiashui, and then entered Hanshui, all the way through Jinzhou and Yangzhou, and came to Xingyuan Mansion.

Before leaving, Yun He also found Gao Yue, and said that when she was in the transfer yard, she saw a small boat with her own eyes, and when crossing the clean beach, the water was too fast, rushing to the boulder of the waterlogged beach, and several penny masters were still holding on to the last bit of hope before the boat was smashed, stretching out the penny, trying to resist the boulder and prop the boat open, but what answered them was a terrifying loud noise - Yun He saw that the penny and the boat were bent and disintegrated on the boulder together, and the group of penny masters who fell into the water and carried the goods were all swept into the churning and undulating rapidsand disappeared without a trace.

So when Yunhe said this, his face was pale.

And Han Rong's four Qianhu ships were able to successfully come to Xingyuan Mansion because of their excellent technology.

"I told it to never be anyone's mission in the future!" Gao Yue pointed to the boulder of the waterlogged beach and said loudly, "Destroy this obstacle first." ”

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

"Iron and fire are one, and the boulder can be overcome." Gao Yue immediately said the way.

In the torrent, the two Qianhu boats that had set up the pole were connected by iron cables, and then Zhang Xi stood on the helmshed, waved the red flag, and shouted: "Get down the bamboo bundle!" ”

"Whoa!" Xuanrun's crossbowmen and penny masters shouted in unison, and the sound overpowered the sound of the Han River and the waterlogged boulders colliding.

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

"Down!" Zhang Xi shouted again.

The big anchorage on the ship descended the winch and fell into the river, and the boat immediately hit the boulder of the waterlogged beach like Mount Tai, and the water frantically pounded the boat, making a terrifying sound like a war drum.

"Downstream!"

Small rocks on the side of the ship were also thrown down to prevent the ship from rocking.

"Fire the brazier!"

"Whoa!"

Under the stern of the boat, the craftsmen used the four wooden poles stretched out to hang a large iron basin, filled with fine charcoal, and the craftsmen stretched out a long bamboo pole wrapped in a flame. The brazier was lit, and the fire was blazing.

The craftsmen who followed loosened their wheels, and the crossbar was tied to the same reef-breaking instrument forged in the workshop of the Chenggu Iron Official—a large, heavy, sharp iron cone that was more than a foot long.

The large iron cone went down the top of the swinging bar into the brazier, and the green smoke continued to rise, and the craftsmen on board watched it intently until it burned red.

"Put away the brazier, twist the wheel!" With Zhang Xi's command on the helmshed.

The brazier was withdrawn with long poles, and the ropes on the wheels were twisted one by one, and the crossbars, which hung from the large red-hot iron cones, were gradually raised, and then raised, and hung on top of the waterlogged boulders.

"Put!"

In the rapid rotation of the wheel, the iron cone also fell heavily, and with a loud bang, it smashed into the protruding part of the boulder, and soon smashed several cracks, and the high temperature of the cone also wedged into the gap, and the stone burst out a few puffs of blue-white smoke.

The craftsmen and crossbowmen cheered at once.

Then the clapper continued to lift the cone and then slap it down again.

Half of the boulder gradually became more and more broken, and the cracks became more and more obvious, and the water began to rampage through it, wrapping the smaller stones, tumbling and rushing in all directions, and the large stones slowly collapsed and slid down.

"Oh, oh, oh!" On the shore, Wu Xianfu, Guo Zaizhen, Gao Gu, Wan Qian, and the county commanders, county officials, and county lieutenants of Yunxiang Township all let out excited and unbelievable surprises.

Soon, the Qianhu boat, which smashed the waterlogged boulders into pieces, got up, turned the wild fox sails, and slowly retreated.

Two other ships followed, with solid iron balls hanging from their rackets.

The iron balls kept falling, completely smashing the boulders.

The original waterlogged boulder disappeared in less than a day!
