Chapter 691 Copper Bottom Boat

It took less than two days from Lu Fengmei's idea of ​​installing copper plates on the bottom of the ship to making the copper plates.

A total of ten copper plates were produced this time. Lu Fengmei used the method of splicing and fixing the copper plates to the bottom of the ship one by one, instead of directly forging a whole copper plate that could cover the bottom of the ship.

There is no doubt that this method is more time-saving and labor-saving, and the requirements for abrasive tools are simpler, which is suitable for mass production.

Before the copper plate is installed on the bottom of the ship, there is another test, which is to use a shark to conduct an actual test.

In order to test the strength of the copper plate, Lu Fengmei came to the water pit where the sharks were imprisoned.

Along with Lu Fengmei, there is also an equation that is concerned about this matter.

In the beginning, Lu Fengmei came to the puddle with the copper plate, put the copper plate on top of the cage, and tried to let the sharks attack the copper plate.

However, the merman was imprisoned for these days, and he seemed to understand something. He knew that Lu Fengmei had deliberately let him attack the copper plate, but he just couldn't be fooled.

Seeing that this method was not feasible, Fang Fang called Lu Fengmei and replaced him to fight in person.

Sure enough, the merman should have put all his hatred on the equation, and when he saw the equation approaching, he immediately became agitated.

In order to lure the merman to attack the copper plate, Fang Fang put the copper plate on his chest in advance, and then winked at Lu Fengmei to let him open the cage.

"This can't be done, it's too dangerous."

Lu Fengmei didn't dare. If something went wrong, Li Qingman and Song Zhixi wouldn't chop him up.

"Don't dawdle, hurry up."

Equation could not wait any longer and kept urging.

There was really no other way, so Lu Fengmei had no choice but to listen to the formula and open the cage.

The moment the cage was opened, the merman in the water jumped up and rushed towards Fang Fang.

To be honest, Equation was also quite frightened at that time, he didn't expect this guy to jump up so fast, seeing that hideous and terrifying face getting closer and closer to him.

"Fuck you uncle!"

Fang Fang tightly held the copper plate with both hands to block the door of the cage.

The merman was only thinking about revenge, completely ignoring any obstacles in front of him, and with a muffled "bang", he hit the copper plate heavily.

The momentum was so strong that it almost knocked the equation over, but fortunately, Lu Fengmei pushed against the equation behind her.

"Old Lu, good job."

"Let's stop playing, I'm afraid!"

"It's okay, it's okay, it can't come out, let it hit it a few more times."

"I……"

Apart from being frightened just now, the following equations have adapted to this mermaid's routine, which is nothing more than a sudden rush from the water, as long as the copper plate is used to block it, there will be no problem.

After repeated impacts, many impact craters were left on the almost two centimeter thick copper plate, but the force was far from breaking through the copper plate.

On the contrary, it was the merman who was beaten to the head and bled, and still looked like he was not going to die.

"Okay, okay, big brother, don't bump into it, just stay inside."

Like waving a fly swatter, Fang Fang swung his arms fiercely, and slapped the oncoming shark back with a copper plate.

Lu Fengmei took advantage of the situation and locked the cage, finally heaving a sigh of relief.

……

Under Lu Fengmei's personal supervision, the first boat with copper plates on the bottom appeared on the island.

On the shallow seashore, the new version of the boat goes to sea for the first time. Compared with the previous boat, the only difference is the draft.

Because the bottom of the ship is equipped with copper plates, the overall weight of the ship has increased a lot.

There are gains and losses, and if you get a solid bottom, you will naturally lose some speed.

Tried sailing back and forth a few times in the shallow sea, Lu Fengmei showed a happy look on her face.

The boat docked, and Lu Fengmei jumped off the boat.

Fang Yi rushed forward and couldn't help but high-five Lu Fengmei, "Old Lu, it's done!"

Lu Fengmei smiled and said: "The effect is better than I thought. After adding the copper plate, the stability of the hull seems to have increased."

"Okay, with this method, we can finally go to sea safely."

"I'm afraid not."

"Not yet?"

Lu Fengmei said: "Now it's just to prevent the sharks from smashing through the bottom of the boat. If they don't smash the boat, but turn the boat over, it's still very dangerous."

Fang Fang gritted his teeth: "I didn't expect this, it would be really dangerous if the boat capsizes."

"We'll have to think about it again."

"Too……"

It is indeed very difficult to deal with these sharks in the water. In the water, bows and arrows are useless, swords and axes cannot exert their power, and spears are not suitable for fighting in water.

A Yue put forward his own suggestion to the equation, "Why don't you try Harpoon?"

"Yeah, Harpoon!"

The most suitable thing to use in the water is the harpoon, which has low resistance after entering the water. It is equipped with a sharp barbed fork head. As long as it can stab those mermen, it will definitely make them bleed.

Fang Fang looked at Lu Fengmei excitedly, "Old Lu, it's not difficult to get a harpoon, right?"

Lu Fengmei said: "Half a day is enough."

"Okay, then half a day!"

On Lu Fengmei's side, she said she was going to make a harpoon and went right away.

Half a day passed, and sure enough, a special harpoon was brought.

This harpoon is in the shape of a trident, each halberd has an undercut, once the fork hits it, there is no way to escape without tearing off three pieces of meat.

The shaft of the harpoon is made of thin bamboo. Compared with the traditional harpoon, the length has been greatly enhanced. A piece of bamboo is at least five meters long. It is so long that it can attack sharks at the bottom of the water. people.

After the first harpoon was tested successfully, Lu Fengmei continued to make more harpoons.

The new and improved Harpoon has suddenly become the most popular weapon on the island.

……

On this day, Equation, who owns a copper-bottomed boat and a modified harpoon, is preparing for a shallow sea trial.

It has been a long time since I went to sea, and the islanders of Wan Guocheng came to the shore one after another for this trial voyage. Everyone is looking forward to this time to go to sea. They want to witness the power of the copper bottom boat and the special harpoon.

Originally, Equation wanted to go to sea in person, but was unanimously opposed by Li Qingman and Song Zhixi.

Under the current situation, even with a copper-bottomed ship, it is still very dangerous to rush to sea, and they don't want any mistakes in the equation.

And as far as the entire Wan Guo City is concerned, no one can live without the equation, and it is absolutely unacceptable for the city owner to take risks.

Fang Fang wanted to go on the boat to meet those sharks himself, but seeing Li Qingman and Song Zhixi's fierce opposition, he had no choice but to give up and agreed to stay on the shore.

After self-registration, the personnel who will finally go to sea are drawn up, including Lu Fengmei who must personally test the voyage, Blake who is brave and good at fighting, and six other soldiers.

Just as he was about to go out to sea, Tang Guo pointed to the sea and exclaimed, "It seems that a boat is coming."
