Zhao Hao's visit to Danluo Island this time has three main purposes: to attend the graduation ceremony of the Coast Guard School, visit the trial voyage of the new warship, and then inspect the newly occupied islands.

Therefore, on the second day of the graduation ceremony, three new warships named "Prajna", "Mando" and "Gala" in Jiangnan Shipyard were used to quietly untickle the cables in the mist and set sail.

The three giants in the security area, except for Zhu Jue left on duty, the other two went out to sea with them. Although they were trial sailing in the shipyard, from the sailors who were driving the ship to the captain who was commanding, they were all crew members selected in the security area in an established manner.

In fact, since the first piece of wood was removed, the guard area had already sent coast guard officers and soldiers to participate deeply. This would help you better understand the structure and manufacturing process of each part of the warship. In this era when it was possible to drive and repair ships, this was very important.

The escort of the trial fleet and Mr. Zhao were twenty large and small warships led by the Zhenwu. The Jiangnan Group blocked the financial path of too many forces, and the seemingly undercurrents on the calm sea surface were surging, and there was no need to be careless at all.

After the trial fleet left Chengshan Port, it sailed to the guard zone shooting range north of Niudao. Mr. Zhao couldn't wait to see the new artillery developed by his eldest nephew!

Chu Liuxiang, who was the test gunner, had already become familiar with the use of this gun in advance. He took out the key, opened the lock, and opened the wooden box covering the fire door.

Zhao Hao saw that the small hole in the cannon sound was missing, and replaced by a device similar to a flintlock bolt.

The sillock paper that Zhao Shizhen showed for Zhao Hao finally became a reality after 18 months of research and development.

In fact, if the gun is small and the cannon is big, the bolt cannon cannon cannon cannon machine of the same principle is naturally no problem. But how to perfectly integrate it with the cannon body, how to improve the success rate of flintlock, how to fire the gunner, etc., it takes time to explore. That is, Zhao Shizhen has a genius intuition. If someone else comes to research and development, he will probably not be able to solve it for a few years.

At this time, the loader completed the ammunition loading, and the deputy gunner quickly put a pull rope on the trigger.

Behind the gun machine, there is also a mountain-shaped sight with a scale. Chu Liuxiang used the sight and turned the "elevation snail" with both hands to aim for the initial sight.

After the initial sighting, the deputy gunner put the launching medicine into the medicine room, covered the air cover, then stepped back and tightened the rope, and entered the firing preparation state.

Chu Liuxiang also took a step back, stood in a safe position directly behind the cannon, and leaned over to make the final aim through the sight.

In the sight, the big white circle painted on the mountain wall two miles away rose and rose with the waves. When it was located two grids below the center, Chu Liuxiang shouted decisively: "Fire the cannon!"

The deputy gunner suddenly pulled the rope, and the hammer hit the anvil, making a cluster of Mars igniting and launching medicine. Almost at the same time, with a loud bang, the shells whistled out, hitting the bull's eye!

Mr. Zhao took the lead in applauding.

Chu Liuxiang's artillery team ignored the trouble caused by the leader, quickly cleared the barrel, reloaded, reset, aimed, and fired. Ten shells were fired one after another, all hitting the target, and seven of them hit the bull's eye!

"Okay, the design is very successful! The cannon king's skills are also superb!" Zhao Hao buzzed his ears and did not forget to cheer.

"How is it, uncle, can you still do it?" Zhao Shizhen happily came forward.

"I think it's." Zhao Hao nodded with a smile and said, "But I said it's useless, it depends on how the user experience is?"

"Then tell me, hurry up." Zhao Shizhen urged Chu Liuxiang who was standing by the side.

"This cannon is very good, twice as accurate as before." Chu Liuxiang thought about it and replied: "The flintlock device is great, but the sights and elevation snails also have a great effect. There is also the 'geometric foundation' for learning in the artillery class, and the 'plane triangle' is also very useful..."

"Good guy, you're really a man who has been separated for three days. Chu Liuxiang is so stubborn now." Wang Rulong couldn't help laughing at Jin Ke on the side, "I'm afraid I'll erase your credit."

Of course, Jin Ke didn't hear it.

"Anyway, it's definitely much better than before." Chu Liuxiang concluded.

"There are no shortcomings?" Zhao Hao asked with a smile.

"It's just that the firing rate is 2 seconds slower than before, but the problem is not big. All gun crews can easily shoot one shot within 30 seconds." Chu Liuxiang replied after thinking about it.

Because the firearm is operated by a single person, the flintlock gun fires much faster than the flint gun.

However, the artillery is operated by multiple gun groups, and the flintlock cannon is not as fast as the medlet cannon... It is mainly because the latter omits the installation of launching drugs.

However, in response to the problem that the bronze artillery fired too quickly in the previous battle against Japan, resulting in overheating, deformation and scrapping of the barrel, the Firearms Research Institute suggested that the security area modify the instrument and stipulate that "unless an emergency situation, the firing speed of one shot should be maintained for half a minute." So this problem is not a problem.

"It seems that the Cannon King's evaluation is quite high." Zhao Hao smiled and said to Zhao Shizhen: "I will remember you a merit. There is no problem after the test is finished. Let's start mass production."

"That's great. Uncle, I can reward Oda City to my nephew this time, right?" Zhao Shizhen asked happily.

"Don't worry, the time is not yet. We won't go to the Japanese islands to mix together this time. We will only patrol our small islands during the trial voyage, and then go back." Mr. Zhao was so angry.

It is now the fifth year of Longqing, 1571 AD, and the second year of the Motokaku in Japan. Oda City’s husband, Nagamasa, only betrayed the alliance with Nobunaga Oda last year and will be attacked for two years.

My husband in Ashi is still alive, so I want to get him at this time. Although it is very exciting, it is really not suitable... and I can't do it either.

Zhao Hao had no choice but to continue painting cakes for his eldest nephew and said, "Wait a little longer, at most two or three years, this matter will be done."

"Oh, okay..." Zhao Shizhen sighed in disappointment.

In fact, he is the same age as Zhao Hao, and he is only eighteen. Mr. Zhao doesn’t know how anxious he is?

This is what an uncle is. A full man doesn’t know that a hungry man is hungry...

~~

After watching Chu Liuxing fire, Mr. Zhao prepared to go back to the cabin.

Chu Liuxiang led the members of the artillery team to salute Mr. Zhao.

"Yeah, I'm already a policeman, it's not bad." Zhao Hao looked at his training uniform with a thick red bar embroidered, and smiled with relief: "It's progressing very fast."

Chu Liuxiang then grinned honestly, then hesitated for a moment, took out two eggs from his pocket and handed them to Zhao Hao.

"Is this?" Zhao Hao took it and saw a small word "Happy" on the egg. "Happy egg? Did you give birth?"

"Well, today is exactly one hundred years old. Please invite the young master to eat the wedding eggs." Chu Liuxiang smiled happily and said, "This is freshly cooked this morning."

"Have you eaten?" Zhao Hao asked Jin Ke and others beside him with a smile.

"I'll eat it in the full moon." Wang Rulong and others laughed and said, "This kid is worthy of being the King of Cannon. He hits the starter and becomes a father for ten months! And he is a pair of twin sons."

"What a good guy, you really have it." Zhao Hao smiled happily and said, "Have you named it?"

"One is called Chu Zhongzhao, and the other is called Chu Fengzhao." Chu Liuxiang quickly said with gratitude: "Let them never forget everything in the Chu family, including their lives, is given by the young master!"

"Oh, don't say that, it's mainly the result of your own efforts." Mr. Zhao waved his hand modestly and smiled: "We didn't help much."

~~

After returning to the cabin, Mr. Zhao held an equipment meeting and announced that the flintlock cannon was classified as the highest confidential level.

This means that all flintlock guns and gun machines must be numbered and kept confidential and no one is allowed to leak information. After the gun machine is damaged, it must be transported back to the base. The old can be exchanged for new ones, discarded or intentionally damaged, and all must be punished severely.

In addition, flintlock cannons are only installed on the main battleship and must be locked and stored when not in use. If a shipwreck occurs, the flintlock mechanism should be demolished. In short, it is necessary to copy the imitation of competitors as much as possible to maintain this advantage for a long time.

In addition, Zhao Hao also sought the opinions of the main generals and agreed to Zhao Shizhen's report on equipping with larger caliber artillery for a new type of warship.

In the past year and a half, Zhao Shizhen also tried to attack the problem that Yongle cannons could not penetrate thick boards of Western warships 300 meters away. He completed the test of two large-caliber artillery artillery 148 mm and 163 mm, which significantly increased the power of the artillery. The shells of these two types of artillery artillery reached 8.3 kg and 11.6 kg respectively, and both could break the defense of the Galen ship at a distance of 300 meters. Especially the latter, after being shot into the hull, it would cause great damage.

Previously, due to the limited structural strength of traditional Chinese sailboats, even the strongest Wanhu Wuwei boat could only be equipped with 117-caliber Yongle cannons, and they could not exceed 20. Otherwise, there would be a risk of disintegration as many volleys were fired.

Now that there is a stronger hull structure, this limitation is lifted, the larger the caliber of the gun.

Of course, the consumables of the two large-caliber cannons are amazing. The copper material required for a 163-caliber cannon can cast two Yongle cannons.

Fortunately, Jiangnan Group is now well-off and can afford this money!

Zhao Hao named the 148mm cannon as the Super Yongle cannon. As for the 163mm heavy cannon, it was named the Hongwu cannon.

As for how many doors are best to install, we need to slowly explore them in actual combat.

~~

In fact, the gun test is not the focus. The top priority of this test sailing is to test the actual effects of the three types of sailing equipment.

In the next few days, the three ships conducted sail equipment tests together.

As Yang Fan expected, when the wind was down, the Mando, which installed the cross sail, took the lead. When the wind was up, the Boruo, which used the sail, was far ahead. The Gala, which combined the two sail tools, won two second places.

In the following steering test, the operation of the Boruo signal is very simple, and the steering is the most flexible.

In the strong wind test, the Poruo sailing is the easiest, and the crew only needs to stay in a safe rear cabin and do not have to risk slippery dangers to work on the front deck in the wind and waves.

Damage and maintenance tests, the superiority of the sail is incomparable. Not to mention, the sail only needs one-tenth of the sail driver of the Western sail...

Finally, the people who served as judges gave the sail a very high score.

But the two Flang judges, former Portuguese Navy Colonel Pinto, and former chief ship craftsman Blanco, had different opinions.
Chapter completed!
