Xingdao County is located on the east side of Hanzhong Basin, about 130 miles away from Nanzheng. It is bordered by Qinling Mountains in the north and Bashan Mountain in the south. Twenty-two tributaries of the Han River from the north and south pass through the city from west to east. The water surface in this section is open and gentle.

, the river bed is stable and suitable for building docks and wharfs. Take a boat down the Han River for more than 20 miles and then enter the mountainous area. Along the way, there are high mountains and deep valleys, many dangerous shoals, and fast currents. It is difficult for enemy warships to go upstream and occupy the

Natural geographical advantages for the downstream.

On February 27th of the first year of Yongchang (AD 322), thousands of people set out from Nanzheng and marched toward Xingdao County. Today was the day Geng Liang returned to Jiankang. He led four of his entourage

We will take a boat in Xingdao County and go straight to Wuchang along the Han River. Yunfeng takes Liu Yueru, Yao Jing, Geng Wenjun and other women to see him off with his bodyguards.

The flowers were blooming and the atmosphere was warm. Yunfeng regarded this trip as an outing for the girls.

At the same time, and most importantly, Jiang Yan, some craftsmen, several middle and low-level generals allocated to him by Yunfeng, and the five thousand soldiers recruited for surrender also set out today to go to Xingdao County to formally establish the navy. Yunfeng naturally

It is necessary to inspect various aspects such as vessel training at the dock.

The navy training period is long and expensive. Compared with the cavalry, it is not much worse, or even worse. The 50 million Yunfeng entrusted Dou Tao to escort can only be used for infrastructure construction and training of sergeants.

, it is really used for shipbuilding. If it is a main battleship, it can be up to about a hundred ships.

There was no way, the reconstruction of Qinzhou and the capture of Yizhou required a lot of financial support. Yunfeng could only spend so much money to build a naval army. He pinned his hopes on Li Xiong. After being the emperor for more than ten years, his net worth

It should be ok?

In fact, there is the simplest and fastest way to develop a navy, which is to recruit sailors from enemy ships. Yunfeng couldn't help but be concerned about Gan Zhuo, the governor of Liangzhou. This man had a navy of ten thousand people. Since Yunfeng

The military commander of Liangzhou will naturally not let him slip away from the palm of his hand. Sima He's edict must be fully utilized!

Along the way, through Jiang Yan's introduction, Yunfeng also roughly understood the types of warships of this era, which were divided into building ships, fighting ships, stern ships and walking boats.

The building ship is a well-deserved giant on the water. It is five stories high and more than ten feet tall. It can accommodate thousands of soldiers. It looks majestic and majestic. There are spears and flags on the ship. It is heavily guarded and capable of attack and defense. It is like a water fortress. However,

, its center of gravity is high and its stability is poor. Not to mention sailing, it can easily capsize in strong winds and waves in the Yangtze River. It is beautiful but not practical. It is just a showpiece.

Fighting ships were the main battleships of this period. They were used for assault and charge. They were narrow and long in shape, fast in speed, covered with rawhide on their backs, with spear holes for crossbows, and powered by oars. They were light and fast, and were usually tied to large boats.

In the back, it is used as a reserve for transporting troops.

The whole army camped for a night's rest midway, and arrived at Xingdao County at noon the next day. After sending Geng Liang away, Yunfeng, Jiang Yan and his party arrived at the dock.

If Jiang Yanxing hadn't sworn that this was the pier, Yunfeng would really not have believed his eyes. There were sparsely uneven thick wooden piles standing on the river bank, and only a few were tied with ropes, and most of them were already gone.

It is decayed, with scattered remains of plank roads interspersed here and there. The wharf in Xingdao County was left by Jiang Wan, but after decades of wind and rain erosion, it has become dilapidated.

Jiang Yan seemed to understand Yunfeng's thoughts, and turned around and said: "General, please rest assured, it won't be long before this place will be restored to the grandeur of our ancestors."

Yunfeng nodded, but said thoughtfully: "By the way, were the ships built on the shore? Are they not afraid of being washed away by the water? Why not dig a dock?"

Jiang Yan was startled and puzzled: "What is a dock? Shipbuilding has always been carried out on the shore, and civilians guard the ships on weekdays to prevent them from being washed away by the water."

Yunfeng understood that there were no shipyards in this era, so he explained: "The so-called shipyard is to build a deep pool on the river bank that is closed on three sides, with one side facing the water, a gate installed on the side facing the water, and a set of brackets at the bottom of the pool. If you build a ship, you can

Close the gate, evacuate the accumulated water, and build a

It is better to divert water and sail into the river. To repair the ship, the opposite is done. The ship is driven on top of the support in the pool, then the gate is closed, the water in the pool is drained, and the ship is suspended on the support. In this way, it can be built or repaired, and it does not want to be washed away by the water.

Walking away can also save people's manpower, and only needs to arrange dedicated personnel to maintain it."

The more Jiang Yan listened, the wider his mouth opened. For him, this was really a genius idea. Although digging a pool was a bit troublesome, the benefits were obvious. It could be solved once and for all, and the speed of shipbuilding and repair could also be accelerated a lot. He couldn't help but praise it.

: "The general is talented and intelligent, and he can make a lot of sense immediately with one word. I admire him very much."

Yun Feng was not modest either. He smiled slightly and said: "People have their strengths and weaknesses, but we just have to make the best use of them. Besides, Mr. Jiang's naval training is beyond the capabilities of this general."

As soon as he raised his eyes, Yunfeng saw boatmen repairing the ship not far ahead. He immediately called out: "Come on, Mr. Jiang, let's go up and have a look."

When a group of people came closer, Jiang Yan was about to order the boatmen to greet him, but was stopped by Yunfeng with a wave of his hand. Instead, he observed with interest. The boatmen didn't pay attention, and they were all busy, as if they were not aware of the people coming behind them.

Judging from the body shape, this should be a stern, one of only a dozen boats that have been collected. The exterior is not covered with rawhide. The hull is damaged in many places. Some parts have been unloaded. It can be removed from the ship's warehouse.

Looking from one end to the other, it seems that the board is ready to be reinstalled.

Yunfeng looked at it and felt that something was wrong. There was something wrong with the structure of the ship. Why was there no keel? He couldn't help but squat down and asked, "My father-in-law, can you excuse me?"

"What's the matter?" an old boatman asked without raising his head while fiddling with his work.

"Why is there no keel in the ship's warehouse?"

"Tsk~" The old boatman turned around and saw that Yunfeng was wearing casual clothes, not in a very luxurious style. He immediately sneered and said: "Dragon bone? Is this gentleman kidding? Has anyone seen a dragon's bone? Where is it?

?”

"Bold! How dare you commit the following crime in front of Liangzhou Mu and Nanzheng Marquis?" Jiang Yan said angrily.

The boatmen quickly turned around and saw a dozen sergeants in soft armor standing behind them, and one in a general's uniform. This man was naturally Jiang Yan. They all stood up, not knowing what to do.

Seeming at a loss, the old boatman even knelt down in front of Yunfeng and begged: "I deserve to die. I am blind and ignorant. Please punish me."

Yunfeng shook his head, held on to his support and said: "I'm sorry, sir, please get up. I'm not a young man. Besides, it's my fault that I didn't make it clear. I shouldn't be offended, haha."

The old boatman thanked him repeatedly, but he no longer dared to squat with Yunfeng and stood aside timidly.

Yunfeng had no choice but to think about it. People in ancient times were like this. They were afraid of officials like tigers. They could only slowly change in the future. He stepped forward and said kindly: "I am afraid I have misunderstood. What I said is that the keel is nothing more than the skeleton of a ship."

, plays a load-bearing role, can strengthen the hull and improve the ability to resist wind and waves."

"Oh? General, can you elaborate?" Jiang Yan asked doubtfully, and there was also a hint of confusion in the eyes of the other boatmen.

"Please wait for a moment." Yunfeng then ordered his guards to get paper and pen.

Not long after, the guards returned with paper and pen. Yunfeng took it and explained it while drawing pictures. Everyone was an experienced boatman and quickly understood the structure of the keel. Everyone, including Jiang Yan, looked shocked.

, Needless to say, the purpose of the keel. With it, the warship not only greatly increased its sturdiness, but also increased the deck area. They couldn't help but look at Yunfeng with an incredible look in their eyes. They couldn't understand this.

How could anyone have such a genius idea?

In fact, Yunfeng has long been accustomed to this kind of gaze. Maybe he would have been complacent a few years ago, but now he can no longer make any waves and is numb. Next, he drew a structural diagram of the watertight warehouse, and another

Wonderful idea!

Jiang Yan's brain was in a state of panic! What Yunfeng said today subverted his lifelong shipbuilding concept. There was no way, it was too advanced. These things would only appear one after another hundreds of years later. But he felt more in his heart

In order to inspire, wouldn't a ship built in this way be invincible in the rivers and seas?

Yun Feng poured cold water on his head and reminded: "Mr. Jiang, everyone, please keep this method strictly confidential and don't let it get to the downstream."

Everyone also knew that the matter was of great importance and hurriedly agreed.

Yunfeng glanced over unintentionally and saw a pile of bamboo nails on the ground, so he asked Jiang Yan: "Are bamboo nails used to fix the hull of the boat?"

Jiang Yan saluted and said: "General, what do you think?" He somewhat sensed Yunfeng's temper. This person did not ask or express his opinion, but expressed his agreement. Once he pays attention to a certain aspect, it means that there is a problem in that aspect.

Yunfeng nodded and said, "How about using iron nails instead?"

Jiang Yan was startled and suddenly realized: "Good advice, General, I understand."

There was a hint of sadness in Yunfeng's heart. He originally planned to spend 50 million yuan to build a hundred main warships, but after so much trouble, it would be great to be able to build ten ships. There are shipyards, blacksmith workshops, and various supporting facilities.

Facilities cost money, but fortunately there are Qinling and Daba Mountains near Hanzhong, so the timber is safe.

At this moment, a bodyguard came running up on horseback, dismounted and saluted: "General, there is a monk (monk) in Nanzheng who is seeking an audience. He calls himself Zhu Faya."

There was confusion on Yunfeng's face. He had never heard of this name.

Jiang Yan explained in due course: "Zhu Faya is a famous Taoist in Jie Zhao, and he studies Buddhism under Qiuci Taoist Fotucheng." Then he frowned and said: "Could it be that the general suppressed the Buddha? If so, the general can get it

He is easy to deal with, and this person is quite famous in Jiangdong."

Yunfeng cupped his hands and said, "Thank you, Mr. Jiang, for reminding me." He then ordered to his bodyguard, "Let him wait for now so that he can keep an eye on Zhu Faya, and give orders to move around as he pleases. Contact with the people is strictly prohibited until the general returns."
