The soldiers quickly moved out a few trebuchet parts wrapped in oil paper from the ship, the giant trebuchet could not be transported by a ship of five hundred stones, so they could only send a batch of medium-sized trebuchets, the trebuchet sent disassembled parts, which needed to be installed by special craftsmen, although there were professional carpenters in the Daimyo's Mansion, but the Daimyo's Mansion itself was a hundred miles away, and it was gone for two days, Li Yanqing couldn't wait for such a long time, so he could only find a few carpenters from his hometown to help.

Two hours later, the soldiers brought with them seven or eight carpenters, so there used to be a shipbuilding workshop in the town, and these carpenters were all shipbuilders, and the first was an old man of sixty years old, with white hair, but still in good spirits and red faces.

Everyone stepped forward to give Li Yanqing a salute, and Li Yanqing led them to the disassembled trebuchet parts, pointed to the parts, and said, "Can you assemble these speculative machines?" ”

"As long as you have drawings, it's easy to fight." A middle-aged carpenter said.

"No, you don't!"

The old carpenter waved his hand, "This thing is actually very simple, the key is to make it strong, and the mortise and tenon joints should be fastened, and then tied with cowhide ropes, and they are not big." ”

Li Yanqing asked expectantly, "Can you fix it on the ship?" ”

The old carpenter frowned, "There is no problem with fixing it on the boats, but these boats are too small and the length of the throwing rod is not enough!" ”

"Nope! No! My husband misunderstood, I didn't mean trebuchets, I meant fixing the cannons on the ship. Li Yanqing pointed to the other cannons next to him and said.

The old carpenter walked to the cannon and gently stroked the thick firing trough, he nodded and said: "It can barely be installed, but I have a word in advance, this kind of cannon is not a marine cannon, it will shake violently when fired, and if you are not careful, the ship will be in danger of capsizing, the general has thought it through." ”

"As long as it can be installed, I don't know how much time it will take?"

The old carpenter thought for a moment, "I can finish it in a day and a half!" ”

A day and a half was too long, and Li Yanqing said again: "What if only three planes are installed? ”

"If you only install three, you can do it before dark!"

Li Yanqing clasped his fists and saluted, "Then there will be everyone, and there will be heavy thanks after the matter is completed!" ”

The old carpenter nodded, he went up and rummaged through the tool bags, all the tools were used, but they didn't need to go back to get them, he took off his coat and said to the carpenters, "Let's do it!" ”

The carpenters took off their coats one after another, revealing their strong and shiny muscles, and they stepped forward to unpack the cannon packaging, and under the command of the old craftsman, they first erected the cannon firing groove and began to install the bracket.

Li Yanqing urged Ma to come to the Yellow River, staring at the vast river, and he didn't know if the fleet on the other side had arrived........

The 20 ships of the Liangshan Army arrived at the wharf of the Yellow River in Yanggu County at dusk, and the Liangshan Army did not have a large ship of 1,000 stones, and the largest cargo ship was only 500 stones, all of which were previously captured by officers and soldiers to transport grain, and the 500 stone cargo ships could transport 100 people at a time, but the Yellow River was stormy and could not be fully loaded, so a boat could only transport 80 people across the river at most, and 20 ships could carry 1,600 people at a time, and 5,000 support troops could be transported across the Yellow River in three times, so as to strengthen the defense strength of Shen County.

However, the Yellow River could not be crossed at night, so it had to wait until the next day after dawn before sending soldiers far away.

Early the next morning, a low horn sounded, and 5,000 soldiers of the Liangshan Army temporarily stationed outside Yanggu County rushed to the wharf of the Yellow River and began to board the ship in a group of 80 people.

The sails were hoisted, the cables were untied, and the first five ships full of soldiers left the dock and slowly headed for the opposite shore......

At the same time, Shen County also received the news that reinforcements were coming, but the defenders of Shen County did not dare to go out of the city to meet them easily, and their spies found an ambush in the woods a few miles away from Xicheng, and the neighing of war horses exposed their tracks.

Zhang Cen stood on the city wall, looking at the large woods five miles away in the northwest, his spies found that there was a cavalry ambush in the woods, about a thousand people, which made Zhang Cen nervous, but also made him in a dilemma, if he went to receive reinforcements, the army sent less, will be ambushed by cavalry, if the army sent more, Shen County may be dangerous.

At present, the biggest disadvantage of the Liangshan army is the asymmetry of intelligence, the other party knows how many troops they have, but he Zhang Cen does not know the details of the other party, how many troops did Li Yanqing lead? He only knew that there were a thousand cavalry, what about the infantry? How many infantrymen are there? If the Song Dynasty army was to follow the convention of one to five foot cavalry, there should be 5,000 infantry.

Zhang Cen could never have imagined that Li Yanqing originally only had 1,000 cavalry and no infantry, but he implemented reforms by himself, and the heavy cavalry became light cavalry, and the auxiliary soldiers became infantry, which formed a mixed battalion of infantry and cavalry, which was completely different from the Song army's five-to-one infantry and cavalry.

"General, do you want to send troops to the docks to pick you up?" One of the generals couldn't help but ask.

Zhang Cen sighed, "There are ambushes outside, and without my orders, you are not allowed to act rashly!" ”

There is indeed an army of more than 1,000 people in ambush in the woods five miles away in the northwest, but it is not like the 1,000 cavalry found by the spies, but only 200 cavalry, 800 infantry, the cavalry is on the periphery, the infantry is in the middle, each infantry rides a horse and mule, these war horses and mules are the Liangshan Army transport team captured in Bozhou, the varieties of mules are tall horses and mules, currently carrying grain and grass for the Xuanwu battalion, temporarily pretending to be war horses, from a distance it looks like a thousand murderous cavalry.

However, the main cavalry force of the Xuanwu battalion was deployed near the dock, and Li Yanqing could not allow the reinforcements of the Liangshan Army to enter Hebei under any circumstances.

........

Today, the wind on the river is not strong, it is very suitable for crossing the river, the first batch of five troop carriers have sailed through the middle line of the Yellow River, and the black line on the north bank is already faintly visible, at this time, three transport ships of the same size as them are heading towards them, and the boatmen wave their flags and signal the boats on the opposite side to pay attention to avoid, they do not realize that the comers are not good at this time.

The three ships were equipped with artillery cannons, but the artillery was temporarily covered by the tarpaulin, and it looked like a transport ship full of goods from a distance, and the ship did not avoid it, and sailed directly to the troop carrier of the Liangshan Army, when the bow of the two ships was only a hundred steps apart, the tarpaulin was withdrawn, revealing the swarthy cannon, the cannon had been wound, and a nearly fifty pound earth-shattering thunder was placed in the magazine.

A soldier disguised as a boatman lit the fuse on the Sky-Shaking Thunder, and the lead burned with a sneer, emitting white smoke, and quickly spread towards the mouth of the Sky-Shaking Thunder, at which point, the soldier shouted, "Release!" ”

"Bang!" The cannon was launched, and the earth-shaking thunder was ejected, and the ship shook violently, and the ship immediately turned around, but unfortunately the earth-shaking thunder did not hit the ship, flew over the ship, and fell into the water behind the ship, only to see a column of water rise into the air, and suddenly the white waves were surging, and the ship shook violently, so that the soldiers on the ship shouted and screamed.

The second ship's earth-shattering thunder hit the side of the ship and also fell into the water, but as soon as the earth-shaking thunder entered the water, it exploded violently, and the strong shock wave set off a huge wave, the boat suddenly capsized, and the shamprapnel penetrated the bottom of the ship at the same time, and a large amount of river water poured into the boat, and the soldiers fell into the water one after another, crying for help.

At this time, the third ship successfully shot a sky-shaking thunderbolt into the opponent's ship, the earth-shaking thunder exploded in the boat, and there was an earth-shattering explosion on the river, flames burst out, and thick smoke quickly shrouded the river, the whole ship was blown to pieces, and a boatload of eighty soldiers and several boatmen were all killed, and when the white smoke cleared, the water was full of wreckage of ships and soldiers.

The other three troop carriers were so frightened that they turned around and returned to Yanggu County, and the fifteen large ships that set off behind also stopped advancing and had to temporarily return to the south coast.

On the north shore, Wang Gui smiled at Li Yanqing and said: "Actually, I don't think I should scare them, so I just let them go ashore, more than 1,000 people are just one of our dishes." ”

Li Yanqing smiled faintly and said, "You will eat this dish, they are only temporarily frightened, and they will make a comeback soon." ”

Wang Gui understood, he understood what Li Yanqing meant, but Niu Gao was confused, scratched the back of his head and asked puzzledly, "Why do you come again?" ”

Wang Gui turned around and knocked on him, "You bull head who doesn't know the idea, this is the same thing as attacking the city, the soldiers fled back without permission, is the main general going to collect the troops?" ”

Li Yanqing said with a smile: "Agui is right, unless Song Jiang changes his order, the main general on the opposite side still has to continue to transport troops!" ”

Wang Gui's face flushed, glanced to both sides, and whispered to Li Yanqing: "I think it's better to call General Wang, don't call it Agui, the soldiers will lose their dignity when they hear it." ”

Niu Gao pursed his lips, "You call me Niu Tou and you don't lose your dignity?" ”

At this moment, suddenly a soldier pointed to the river and shouted: "They have turned around!" ”

Everyone looked at the river, only to see more than a dozen troop carriers that had already gone away and turned around and headed for the north bank of the Yellow River.

"General, do you want to blow up a few more?"

Li Yanqing shook his head, "Since they are not afraid of warnings, let them feel the pain of skin cutting again!" ”
