Under the care of the Dagukou Banner Army, the goods transported from Beijing were unloaded from the sea ship, loaded them into the canal ship, and drove to Tianjin by defending the river.

The upcoming preparations for the long voyage made the Beiyang Military Mansion busy, and various raw materials sent to the military mansion from the canal were continuously flowing, and were processed into available arms at the Beiyang Military Weapons Bureau.

"There is not much time left, how about it? Let me give you a long vacation and go back to my hometown in Fujian?"

In the backyard of Beiyang Yamen, in Chen Mu's mansion, the heroic Yang Tingxiang was invited by Chen Mu. "You went to sea for more than a year and should have given you a rest, but the eastern expedition is imminent, and the fleet needs you to lead the way. Now, go back and wait for the final preparations of the military mansion to be completed in a few days. You are about to set off. I heard that you have been eating and living with craftsmen in the Beiyang shipyard recently?"

Speaking of which, since the arrival of Nanyang Beijing ship, it was colliding with Beiyang to discuss the expedition. Chen Mu never cared about Yang Tingxiang. When he suddenly remembered to inquire, he heard that Yang Tingxiang had been in the Beiyang shipyard.

The Beiyang Shipyard is a big name, and Chen Mu's shipyard is also very positioned. It is a shipyard that specializes in building large warships of more than 1,000 materials.

As early as the beginning of the factory construction, a group of skilled old shipbuilders were transferred from Xiangshan, Nanyang and other places, and recruited many craftsmen to learn from corvee, building twelve dry docks that were 18 meters long.

But the completion date is still short. The twelve thousand-capacity Chihai-class warships built have just begun. Moreover, this large ship requires much more labor and material than ordinary ships. It is expected that the earliest launch time will be at the end of autumn this year. If winter has not yet recovered early, it will be delayed until the spring of the following year.

"Thank you, Chen Shuai, thank you for your kindness. However, I would rather stay in the shipyard until the fleet sets off." Yang Tingxiang had a calm temperament. He took a small sip with his porcelain tea bowl, then looked at Chen Mu and bowed: "This time he traveled to the West for a year, and he was planning a new warship at most. Chen Shuai also knew."

As he said that, Yang Tingxiang smiled introvertedly and said, "I studied the Warship Department in the Naval Martial Arts Hall. Both my father and brother were craftsmen. They also had the ancestors who were lucky enough to join the royal palace as chief ministers because of their superb craftsmanship. They felt deeply that craftsmen did not know about military affairs and soldiers did not know about craftsmanship. They wanted to design a warship shape for the court that was more suitable for today's naval battles."

More suitable for today's naval battleship shape?

"Jun Zan thinks that the shark boat is no longer suitable for use?"

Sailu Gong suddenly felt very sympathetic to Mr. Ge and Shuai Qi. He often looked like Yang Ting, and even spoke exactly the same tone. He proposed his own improvement in front of Zhang Juzheng and Qi Jiguang.

It's really... not likeable!

"Shistor Chen was worried too much. The meaning of the shark boat is not that it is no longer suitable for use. On the contrary, on the way to the Western Country, he saw many large ships. Their country was poor and close to the sea and could only rely on maritime affairs to obtain the needs. Even so, the shark boat is not weaker than any ship type seen in the shark."

"Since Chen Shuai, the Yi Navy was a navy, and he built General Zhenshuo's artillery and shark boats, weak fire boats and heavy artillery battles. He fired a volley of guns on the vertical line, and all the attackers were broken. This is a top-notch excellent warship in the world."

Chen Mu nodded slowly and listened. In his heart, the shark boat may not be that excellent, but for the Ming Dynasty, it was an epoch-making warship that changed the form of naval battles.

Similarly, he also heard what Yang Tingxiang meant. People must have said that only when they found the problem, so he simply said: "But?"

Yang Tingxiang smiled embarrassedly, and saw that Chen Mu was not in a hurry, saying: "But what is suitable for the shark boat is still near-shore war. Whether it is the 100-material small shark boat in the hands of the fishermen in Fujian and Guangxi, the 500-material large shark boat, or the larger Chihai-class, the Six Ding Liujia-class, the limited deck-sized equipment more artillery... There are few sailors, the cabin is crowded, and there is no cargo warehouse."

"A thousand-stock Chihai-class warship can be equipped with twenty to forty artillery pieces, carrying one or even two hundred households of troops. The ship carries only enough water and food to eat and use for fifteen days. The cabin is small but more water and men need to be squeezed into it. The limited gunpowder warehouse is full of shells and gunpowder, and there is no space on the ship."

"In Nanyang, 15 days of sailing are enough for the fleet to patrol the coast. Starting from the Nanyang Guard, Sulu, Luzon, and Borneo can all sail, and all places along the way can be replenished, which is more appropriate; but every time you sail far away, you have to prepare grain ships. During this eastern expedition, I heard that the military government would prepare three, four hundred grain ships for each hundred households."

"More grain ships require more excellent captains, and they also have to bear the risk of ship drifting, but fortunately there are advantages of more ships and guns; but that was when the ship was equipped with General Zhenshuo's guns in the past. Now the enemy we are facing is Western Yi. Most of the time, the five-jin cannons can no longer penetrate the enemy's ship's hull."

"When Chihai-class warships are equipped with forty guns, most of them are five-pound cannons, and even many two-pound small cannons are mixed with them. If they are replaced with ten-pound cannons and five-pound cannons, they can only be equipped with eight ten-pound cannons and eighteen five-pound cannons. If they are replaced with twenty-pound cannons and ten-pound cannons cast by our gun factory, they can only be equipped with six heavy cannons and twelve ten-pound cannons... This is not because the ship cannot load it, but because there is no place for more shells to be placed in the cabin."

General Zhenshuo used thirty-three times the diameter, which was long and heavy. The larger the shell, the heavier the shell, the heavier the artillery.

Chen Mu nodded slowly, and Yang Tingxiang seized the key to the powerful combat effectiveness of the shark ship because their ship sacrificed the cargo load and the relatively smaller artillery.

"What you said makes sense. After all, when designing the shark boat, we only had two kilograms and five kilograms. Later, it developed too fast - what are your plans, let me see."

On the map of the Spanish ship brought back by Yang Tingxiang, the large ship, which is roughly estimated to be 3,000 to 4,000 materials, was only equipped with more than 30 artillery pieces, but the thirty artillery pieces are different from the 40 artillery pieces of the Chihai Ship. The largest heavy gun with a diameter of six inches on the bow is calculated according to the lighting system, which is a heavy gun that uses more than 40 kilograms of shells.

Even ordinary bow guns can still match the Ming Dynasty's twenty-pound heavy guns.

However, perhaps because of the Lin Lai naval battle, the Spanish did not seem to have learned the lesson of the volley of the strait guns. What they valued most was the bow gun.

"The ship diagram has not been designed well, but the general direction is already there, mainly to increase the waterline width and cargo warehouse, reduce the carrying of sailors, reduce the number of artillery, increase the weight of artillery, and also toilets." Yang Tingxiang said with a smile and said, "There are no toilets on the ship. The corridors of Western ships on the outboard side of the ship are very good. They can be used to arrange several toilets, which can effectively improve the environment for long-distance navigation."

At this moment, the military officer entered the hall to report: "Master, Du Qianhu is back."

Du Qianhu was Du Song. He led his servants to live in Qianhu. Chen Mu sent him to Beijing to find out the news in the court.

After getting Chen Mu's permission, Du Song entered for a moment, glanced at Yang Tingxiang, and whispered to Chen Mu.

"Shishuai, Master Ge's father, passed away."
