"There is no horse, but the cow can be obtained." Lu Shihu smiled and said, "Qingzhi, what is the cannon cart you just said? Is there any picture?"

"Of course there are already pictures."

Chen Dexing raised his hand and made a gesture of a sooke, and invited Lu Shihu into the hall. Chen Dexing had no women to serve in the house in the military camp, and only a few older soldiers were serving tea and water. They were all soldiers who followed Chen Dexing from the battlefield. They were nearly forty years old and were already old in this era. Although they were in good health, their learning ability was not as good as that of young people. Chen Dexing didn't expect them to learn the skills of the artillery army, so he arranged for them the errands of the guards.

"Brother Shi, please see, this is the new pattern I made, a motorized torque generator." Chen Dexing took a newly drawn drawing and unfolded it in front of Lu Shihu. This is not a structural diagram, but a plan rendering.

The structure of the stone generator in the figure is more complex and compact, and is composed of two parts put together, including a stone generator mounted on two wheels and a wooden bracket to support the stone generator. The bracket is a frame composed of three woods, which directly connects to the rear of the stone generator and is arranged at about a large oblique angle. When one end of the bracket is buried in the ground, the bottom of the stone generator in front can be approximately parallel to the ground.

This design actually refers to the historical smoothbore gun mount. The bracket behind the stone generator can also be hung on a two-wheeled carriage or ox carriage to form a four-wheeled carriage (ox carriage), which gives the stone generator a certain mobility.

Lu Shihu's eyes slowly swept across this picture, and finally landed on the already formed four-wheeled cannon carriage. "Is this... hanging the two carriages together? What a wonderful idea!"

Chen Dexing smiled: "It's just a small path, Brother Lu Shi, please see this picture." As he spoke, he spread out the drawings of a three-layer pulp warship. "This kind of warship is the most commonly used warship in the Mediterranean countries in the Western Regions. It is a weapon produced by more than two thousand years of maritime competition. It is extremely fast and has great combat power. It is just used in the countercurrent of the Sichuan River."

As far as Chen Dexing knows, the Song army's naval army was relatively powerful at this time, with many names such as flying tiger ships, iron head ships, iron harrier ships, front ships, horse-building ships, iron-walled turtle ships, etc. However, none of them could move forward at a faster speed in the countercurrent of the Sichuan River. This gave the Mongolian naval army that occupied the upstream a considerable advantage.

Among the many river warships of the Song Navy, the fastest one was the one driven by the "wing wheel", which was said to be able to travel thousands of miles a day. However, in Chen Dexing's memory, the speed of such vehicles was far less than a thousand miles a day, and they were suspended even if they traveled three hundred miles a day. It was converted into a Western speed calculation unit, which is from four to five kilometers.

Perhaps a carefully crafted ship really reached a speed of thousands of miles a day when it was just launched. However, the durability and precision of the transmission device made of wood are conceivable. When the mechanical device is worn, the performance of the ship will inevitably decrease significantly. Therefore, in Chen Dexing's memory, the vehicles and ships of the Southern Song Dynasty's naval army were equipped with oars at the same time, called "iron-walled squid ships". They are usually driven by oars, and in wartime rescaling trucks (the ancients called wing-wheel drive device) are used together.

However, in Chen Dexing's view, it is still difficult for this kind of iron-walled cruising ship to advance in the countercurrent of more than 10 kilometers per hour. However, in Chen Dexing, the ancient warships that were moving forward in the countercurrent of the Sichuan River were only multi-layered warships from Westerners. If Jia Sidao wanted to go upstream to reinforce Sichuan, he would inevitably need such warships that were famous for their speed.

Chen Dexing, who was a senior seaman in his previous life, was not unfamiliar with ancient ship structures. He liked to make ship models when he was a teenager. Later, he collected many highly simulated ancient ship models, including the famous multi-layered pulp warships - this ancient warship that once dominated the Mediterranean was quite fascinating. He not only made simulation models himself, but also studied the structure and performance of such warships. He knew that the fastest speed of this kind of warship in combat could exceed 10 knots! Even the cruise speed could reach more than 7.5 knots. Having such a speed was enough to allow the multi-layered pulp warships to flow upstream in the Yangtze River and fight with the Mongolian navy, which had the advantage of downstream.

Moreover, the advantage of the multi-layer pulp warship is not just speed, because this ship is just a product of the Millennium War in the Mediterranean, and naturally has the strongest military equipment in the era of cold weapons, including metal horns, crossbows, stone-launched tools and crow suspension bridges used to fight platoons, etc. It is a war machine on the water!

"Three-layer pulp seat..." Lu Shihu seemed to have an unknown meaning, "What does pulp seat mean?"

"It means installing three layers of wood pulp on both sides of the ship's side. Each ship has 170 to 174 pulp, which can be paddled at the same time, which is much faster than the ship."

Lu Shihu was stunned, "Is it really feasible to place three layers of wood pulp on the upper, middle and lower?"

Although ancient Chinese shipbuilders have been trying to make the ship stronger, they have never thought of using a multi-layer pulp seat. Instead, they have adopted the wing wheel pedaling and water-stepping boat design, following the idea that the arms are thicker and cannot twist the thighs. They use the wing wheel driven by the foot to replace the wooden pulp of the arms.

"How is it not feasible? There are three floors of slurry, and the slurry is divided into three floors, middle and lower, just like a building."

The principle is very simple, and it can be said that it can be broken. Lu Shihu was also a general and naturally practiced both civil and military. He was not a nerd who only knew the Four Books and Five Classics. After a moment of thinking, he slapped hard. "The principle is so simple! The pulp is divided into three layers, each layer is more than fifty, and each side is divided into two sides, and each side is only twenty-seven or eight pieces of pulp. How can it not be? The three layers of pulp seats have a total of more than one hundred and seventy or more chariots, and the force must be greater than that of more than twenty cars and ships... By the way, Qingzhi, what is the size of your three-layer pulp seat ship? How many armored soldiers can you carry?"

"The hull is twenty-five steps long and three and a half steps wide. It carries fifty armored soldiers outside the slurry hand."

"Only fifty soldiers? Are there too few?" Lu Shihu's excitement suddenly went away. The three-layer pulp warship that Chen Dexing mentioned seemed to be smaller. At this time, it was twenty or thirty feet long (equivalent to fifty to sixty steps), and there were many Song army warships equipped with thirty or forty vehicles (wing wheels). Although the speed was slower than the three-layer pulp warship, it could accommodate as many as five or six hundred soldiers, of which there were no less than three hundred soldiers who could be used for combat, almost six times that of the three-layer pulp warship!

Chen Dexing smiled and said, "The three-layer pulp warship does not rely entirely on armored soldiers. It installs pig iron angles on the bow to hit the enemy ship, or uses stone generators to shoot fire-driven objects to burn the enemy ship. The impact angle of the three-layer pulp warship is located below the waterline, and the destructive power generated by the impact of a high-speed impact of more than ten knots is not something that a wooden ship can bear!"

Speaking of this, Chen Dexing asked the old army to take the model of the three-layer pulp warship and put it on several cases. This is the model of the third three-layer pulp warship created by Chen Dexing. The hull is slender, sharp bottom, high freeboard, and the bow is equipped with a black impact angle. There is also a model of a stone-generating tool on the first deck.

"Is this... a sea ship?" At this time, the Song army relied on several major rivers such as the Yangtze River, Huai River, and Han River to launch a battle, and the generals were more proficient in water warfare. Lu Shihu, who was born in the Lu family, also knew some knowledge of water warfare, and could distinguish river ships and sea ships.
