When Cao Bao learned that Kong Rong was dead, he felt much more relaxed.

At least the person who used him died before him, and although he suffered a lot, he now has hope of returning to Xuzhou!

Of course, before this, Cao Bao felt that it was necessary to expose Kong Rong's sinister face.

So, Cao Bao told Pan Feng all the things about how he agreed with Kong Rong and how he finally lost contact, and said in the end that he did not forget to say that Kong Rong bullied me too much!

Pan Feng sighed as if he had known Kong Rong for the first time: "I didn't expect that Kong Beihai, who is famous all over the world, is such a person. Fortunately, General Cao is safe and sound, otherwise wouldn't it be that the hero will succeed in tears!"

"In order to wish General Cao to escape from danger, we should drink a big cup!"

As he said that, Pan Feng raised the wine cup.

Cao Bao also raised his glass, his eyes full of emotion: "I am fortunately rescued by the general today. If there is any need in the future, Bao will definitely help you!"

After the words came, Cao Bao raised his wine cup and drank it all.

"Hahaha! General Cao is out of here. With such a hero as General, I, Pan Feng, only regrets that I met too late. Today I am willing to meet General Cao and get out of trouble again. It is the time when the two happinesses are coming."

"Come on, today I will not return without getting drunk!"

"Don't go back if you don't get drunk!" Cao Bao replied loudly.

Cao Bao's alcohol capacity was not good. I don't know if it was because he didn't drink often or something else. After drinking a few drinks, he started to turn red and fell drunk on the table.

There was no choice but to send someone to send Cao Bao down and ask someone to wash and clean him up, and come to see him when he wakes up.

After Cao Bao was carried down, the matter came to an end.

After the conversation with Cao Bao just now and the grace of saving his life, I should be of some help when I have ideas for Xuzhou in the future. If I don’t help, I can use Cao Bao to conquer other counties after conquering Xuzhou. Isn’t that much more convenient than the soldiers using their lives?

In the days that followed, Pan Feng's life returned to normal.

In addition to playing a few times a day with the familiar touch, I also provide some suggestions and suggestions to the navy soldiers trained by Taishici.

Because Taishici has no experience in commanding and training the navy, there is no way to start in many places. Instead, Pan Feng has gained the insights of his previous life and gave tips in some key places, so that Taishici's training will not be stumbling.

In this way, the days passed day by day until the shipwrecks transferred from Bohai came to Huangxian.

In order to allow boatmen to start researching the manufacturing of pointed-bottom ships after they arrived in Huang County, Pan Feng had someone to build a new dock by the beach very early, and when the boatmen were in place the construction of the dock was approaching.

Because of the stability of the pointed-bottomed ship, Pan Feng did not only focus on the inland lake. He also wanted to use the advantages of the sea to launch unexpected raids from the coastline, and all this was inseparable from naval forces and ships.

The disadvantages of flatbeds compared to pointed-bottomed ships are relatively obvious, and the stability of the plungers is destined to be inseparable from the range of the coastline.

However, the pointed-bottomed boat is somewhat advanced in this era, so even though Pan Feng has handed over the drawings, the boatmen still have a lot of doubts.

Look, the shipmaker found Pan Feng as soon as he arrived in Huang County.

Because Pan Feng is the provider of drawings and the conceiver of the sharp-bottomed boat, the ship craftsmen instinctively believed that Pan Feng should know more than them. Before, because Pan Feng was not in Jizhou, and the ship craftsmen in Bohai County could not leave at will under Pan Feng's order, they could only keep their doubts in their hearts.

Now that Pan Feng was about to dispatch personnel, the chief foreman among the ship craftsmen took the initiative to request to go to Huangxian to develop the ship.

Of course, his purpose was to let Pan Feng solve his doubts.

"General!" The ship craftsman saluted respectfully after seeing Pan Feng.

Pan Feng remembers that the foreman was Zhang Chong, an old craftsman with an old face. His thin and chapped hands were covered with scars of time. You can tell at a glance that he was an old craftsman. Pan Feng chose him as the foreman because he had some reputation among the boat craftsmen in the Bohai area, and on the other hand, because of his only talent.

Structural analysis: When studying the same type of creation for a long time, the analysis ability of this creation structure can be deepened, and the ability to improve by no more than 50%.

This talent can improve Zhang Chong's analysis ability of ships. Pan Feng felt that it would be better for him to supervise the construction of a pointed-bottom ship than others.

The practical things were as Pan Feng thought. He only gave the appearance drawings of the pointed-bottom ship and the important component of the keel. The rest were basically found by Zhang Chong himself. According to Pan Feng's latest news, Zhang Chong had built several pointed-bottom ships in the docks on the Bohai Sea, but some of the technical problems had not been solved.

Obviously, this time Zhang Chong came over to ask questions.

Pan Feng was not surprised to see Zhang Chong coming.

"What's the matter with Mr. Zhang?"

Zhang Chong saluted again: "General, although I had built several pointed boats when I was in the Bohai Sea, a problem that has troubled me in the past still exists."

"Ship entering the sea is mostly caused by shellfish erosion in the sea water. If a fishing boat is made simply and easily replaceable, the general's warship hull is huge and complicated. It takes a lot of money to make a ship. It would be a pity to give it up because of sea water erosion. But I still can't solve it if I try my best to solve it. I don't know that the general..."

Having said that, Zhang Chong looked at Pan Feng, obviously wanting to know if Pan Feng could solve the problem of the shellfish adhesion.

In fact, this point is not solved now, even in the era when Pan Feng lived. However, the ship materials at that time were much more advanced than they are now. In addition, there were paints and other paints, shellfish would not have much impact on the ship for a while. As long as regular cleaning and maintenance are carried out, the bottom of the ship can be ensured that the ship is not affected.

But not now!

The ships are all made of wooden. Although the bottom of the ship is polished and oil-soaked, it has become a good place for shellfish to live in. The strength of these wooden hulls is far from the steel hulls of later generations. If they are eroded by a large number of shellfish, it will probably take less than a year or two to drag the hull down. Will another ship be built then?

You know, it costs a lot of money to build a warship even the lightest gantry, let alone a large warship.

At that time, Han Fu will probably have a long pain in his heart.

So, after discovering this problem, Zhang Chong couldn't wait to find a solution, otherwise there would be no turning back when the large warship began to be built!

Not to mention, Zhang Chong’s problem has made Pan Feng difficult.

To be honest, he really didn't know much about ships, and there was no way to remove the shellfish that Zhang Chong said. The only thing he could think of was to clean it regularly.

However, unlike later generations, it is not that easy for large ships to get ashore, let alone clean up shellfish at the bottom of the ship.

Could it be that someone dived down to clean it up? That wouldn’t it cost someone’s life?

This is very embarrassing.

Pan Feng and Zhang Chong looked at me, and I looked at you, but didn't say anything again.

After a long time, Pan Feng sighed: "You go back first, wait for me to think about it before going to find you. In addition, you can also go to the nearby fishing village to ask if anyone knows some folk remedies that can solve the erosion of shellfish. If there is any, it will bring me a look."

"No!" Zhang Chong bowed and retreated.

......

After Zhang Chong left, Pan Feng fell into deep thought.

If you want to solve the problem of shellfish, you cannot start by eliminating shellfish. After all, this is a problem that cannot be solved in later generations, and it will be even more difficult to solve with the technology of this era.

Since we cannot start with eliminating shellfish, we must find a way out of prevention.

Is there any way to prevent ships from being eroded by shellfish? How to reduce the impact of shellfish on ships?

Thoughts flashed through Pan Feng's mind, but they were soon denied by him.

The ships sailing at sea are different from those of inland rivers. The ships sailing outside the sea must not only beware of various shell creatures, but also beware of the corrosiveness of seawater. At that time, there will be fewer shellfish, but they will be corroded by seawater.

In fact, Pan Feng had not thought about using copper or iron to build ships.

But it is almost impossible to use current technology to make a ship built entirely of copper or iron, and copper-iron warships consume more than a wooden warship. More importantly, the power of the ship is insufficient now, and it is very difficult to rely on sails or manpower oars to drive a copper-iron warship.

The key is that the speed is not fast!

If you really encounter a light sailboat, you will probably be able to follow others and eat nonsense!

Moreover, copper can be corroded in the sea, but the corrosion rate is relatively slow.

Since the possibility of copper and iron has been denied, what other materials can be used?

Pan Feng fell into deep thought.

This thought took several days, and Pan Feng couldn't eat well and couldn't sleep. Until Zhang He came to the door again, Pan Feng still didn't find any feasible solution.

In fact, Zhang He has been quite depressed these days.

Because he followed Pan Feng's words and believed that high-end training methods were inseparable from the simplest basic exercises, he had been practicing puncture with his spear at home these days. In order to make his exercise better, he also hung a stone on the tip of the spear to increase the pressure on his arms.

As a result, I have not had much effect in practicing sunrise and resting every day in the past few days, at least not as fast as Pan Feng’s improvement.

If you insist on the effect, Zhang He felt that his muscles became stronger when he used his arms, and there was no change other than that.

He didn't understand what was wrong, so he thought about coming to Pan Feng for a question.

As a result, when Zhang He met Pan Feng, he was stunned.

Pan Feng, who was majestic and mighty a few days ago, is actually a little depressed now!

That's right, it's depressed!

Zhang He swears that he had never seen such a situation in Pan Feng. In the past, Pan Feng was either majestic or mighty, or was imposing. As for now, it seemed to be exhausted by exhaustion of energy, physical and mental fatigue.

Zhang He didn't understand why Pan Feng was exhausted at first, but he suddenly thought that he had sent six singers a few days ago, which immediately understood Zhang He's thinking!

"Ahem, brother, you have to grasp the same degree in everything. Although women are good, they should not be too greedy, otherwise they will eventually hurt themselves." Zhang He whispered beside Pan Feng.

Pan Feng was thinking about the boat, but he was stunned by Zhang He's interruption, and looked at Zhang He for no reason.

Zhang He sighed in his heart, his brother seemed to have a little discomfort.

"Brother, too much is too little!"

At this point, Pan Feng finally came to his senses from the ship matter. As soon as he heard Zhang He's words, Pan Feng laughed out loud.

"Good you, handsome, do you think I'm exhausted for your singers? Fart! I'm for the great cause of the navy!" Pan Feng cursed with a smile.

Seeing that Pan Feng had finally recovered some energy, Zhang He immediately smiled: "Yes, yes, yes, brother is naturally working hard for the great cause of the navy. That... did the brother's habit of using singers before? If you are tired of it, I will send you a few."

Pan Feng was amused when he heard this.

What a guy, Zhang He is going to take over all his future singers? He also gave him one batch? Why don’t you say you’ll change another batch?

Suddenly, a light of inspiration flashed through Pan Feng's mind.
