Wei Minsheng and Li Yan and their entourage went down the river by boat, and under the combined action of the engine and the current, they reached a speed of more than 30 kilometers per hour.

Nearly 200 kilometers of waterway, it took less than eight hours to reach the river near Gangneung City.

After letting the fleet anchor the hull, Wei Minsheng turned up some information about this Jiangling City in the real world:

The whole Gangneung Fortress is an irregular rectangle, 3.75 kilometers long from east to west, 1.2 kilometers wide from north to south, 10.5 kilometers in circumference of the city wall, and an area of 4.5 square kilometers in the city.

Judging from these materials, the current scale of Gangneung City can accommodate tens of thousands of people at most, and in addition to those displaced people who live in the city, more people are still distributed in the surrounding villages.

Wei Minsheng took a look with the ranging telescope in his hand, and the southernmost moat of Jiangling City was still more than two kilometers away from the Yangtze River, because in the face of this moody Yangtze River, the ancients had to ensure a sufficient safe distance from the river when building a city in a flat area.

Otherwise, when there is a rising flood, the walls made of earth and stone will not be able to withstand the soaking and washing of the river.

There are hundreds of large and small ships of the Wu State Navy stationed in the riverside water village, of which there are two largest building ships.

Li Yan next to him pointed to the two building boats and said to Wei Minsheng: "Lord, those two big names are 'building boats', there are four floors on board, ten zhang high, and they can carry more than 2,000 soldiers.

Its main mode of combat is to ram the enemy ship with the ramming angle of the bow, or to get close to the enemy ship and have the soldiers directly board the enemy ship for meat fighting.

Since the size of the ship directly affects the number of soldiers on board, the larger the ship in the case of two ships fighting, the larger the ship, the more advantageous it is in terms of strength.

The slender warship next to the building ship is called '艨艨', which covers the hull with raw cowhide and can block the projectile arrows.

The ship is more defensive, with arrow windows and spear holes in its hull, allowing it to attack at close range.

Due to its long and narrow size, it travels quickly, and the hard impact angles of the bow have a strong impact force, which can easily inflict a surprise blow on the enemy.

In the middle of those ships, which are smaller than the building ships and have golden drums, they are called 'fighting ships', and there are wooden female walls around the fighting ships, and the female walls are arranged with soldiers who can shoot at enemy ships.

Fighting ships have strong defenses and are mainly used to command close to the battlefield.

There are no other small wooden boats that can't withstand the impact of iron boats, and even those water platforms can cause damage to them.

Judging from the number of these ships, there are about 10,000 sailors stationed here in Wu, and the rest of the soldiers should be stationed in Jiangling City. ”

Wei Minsheng looked at the shape of the ship, shook his head, and said, "If this ship wants to improve its troop carrying capacity, it can only increase the floor height of the ship.

But the bottom of the ship is flattened, causing the center of gravity of the entire building ship to move up, and it is good to go against the wind, if it suddenly encounters a strong wind, I am afraid it will capsize.

Moreover, it is not easy to move the manual slurry discharge on the lower level as the driving force, right? ”

"The lord is right, so the ship on this floor must be guarded by fighting ships, ships and other ships, and when fighting, they will try to choose their position on the upper side of the water, so as to use the power of the current to increase the ability to collide with enemy ships."

Wei Minsheng pointed to the cowhide again, and said, "This cowhide is estimated to only be able to defend against flying arrows, and even an ordinary catapult is enough to cause damage to it, not to mention our stone cannons." ”

"The main advantage of this ship is speed and numbers, and it is not easy for ordinary catapults to hit such fast-moving targets.

This kind of ship is okay against other ships, but if it encounters our iron ship, even if it can dodge the dense stone bullet attack, the hardwood ramming angle will not be able to damage our iron ship.

Not to mention those high-pressure water cannons on board, more than capable of sinking them all when it gets close.

Although their ships seemed to be in good formation, wooden ships were wooden ships after all, and even the largest building ship could not withstand the full speed of our iron ship, let alone those small boats. ”

Between Wei Minsheng and Li Yan's conversation, Wu Jun quickly rushed out of three ships in the water village and headed for Wei Minsheng's ship.

Li Yan arranged it through the walkie-talkie, and a golf stone cannon on the side of the ship quickly fired a round of stone projectiles.

With the slow rotation of the cannon body, twenty stone projectiles drew a graceful arc in the air, and with an indomitable momentum, they smashed fiercely on the water in front of the three ships, splashing twenty high columns of water, like a wall of water.

A general on the front ship looked at this scene, his eyes were so wide that his eyeballs were about to fall out, and he hurriedly raised his hand to stop the ship from moving forward.

As a general who has participated in many water battles, he knows very well how difficult it is for the other party to show his hand.

It's not unheard of in a thunderbolt, but it fires slowly and the rocks stay in the air for a long time.

This attack is okay against fixed targets, but it is almost a matter of luck to hit the Clippers, which can come and go freely in this flowing water.

The fireship strategy has been used indiscriminately after the Battle of Chibi, and everyone has already had the experience to deal with it.

Therefore, in the general river and water warfare, it is more dependent on the collision force of the ship itself and the way of jumping gang combat, and it is rare to load a large siege weapon such as a thunderbolt on a ship, because this bulky weapon is not as accurate as a crossbow machine.

But the scene he just saw had completely subverted his perception of the thunderbolt.

The rocks that suddenly appeared seemed smaller than those emitted by the Thunderbolt, but their speed in the air was a world of difference.

The distance of more than 20 zhang is simply instantaneous, and before he has made preparations in which direction to avoid, the stone bullet has already entered the water.

Even more terrifying, the stone projectiles were clearly fired from one of the oddly shaped things in a row next to the largest ship.

Obviously, judging from the neat row of water columns and the direction of the flight of the stone bullets, the other party was just warning himself, otherwise, he only needed to throw a little more upwards, and this round of stone bullets would be enough to cause huge damage to the three ships.

He didn't dare to imagine that if that row of ten identical things were all of such power, what ship would be able to break through its defenses.

In a moment, Li Yan had already led his subordinate Yang Xingbang from the big boat to a water platform, Li Yan and Yang Xingbang stood on both sides of the cockpit, grabbed the protective steel bars around the cockpit with their hands to stabilize their figures, and then commanded the platform to drive directly in the direction of the water village.
