Kyushu Academy of Sciences, a map of Laoshan County was placed on Li Zhen's desk.

There was a circle of people around, and Li Zhen wrote and drew on the map.

"The beach where you can land is three kilometers long."

"Master Li, it's not just three kilometers......

"It doesn't matter outside Laoshan."

"Yes."

Li Zhen turned his head and asked, "I asked you to put the alternating current into use immediately, did you start?" ”

"Master Li, it's still in the testing stage, and the voltage is very unstable. We are also now envisioning a transformer unit. ”

Li Zhen said: "No need. Immediately operational, the best layer of defense is the power grid. ”

"Huh? Power grid? ”

"A three-kilometer-long high-voltage power grid is laid on the ground, and even the gods have no way to pass through it."

"That'...... That's a lot of electricity. ”

"I don't usually open it. When it is turned on, the device is used to cycle electricity, and the flow of electricity will cause electrical loss. But these investments are negligible in comparison. ”

"Grid ...... Wouldn't the pirates use insulators to break through the grid? ”

Li Zhen smiled: "Insulation? It's just relative insulation. When a group of pirates from the sea step on the ground, even if they are wearing rubber and plastic insulated shoes, the water on their bodies will cause them to be hit by the arc even if they are several meters apart. ”

“……”

High-voltage power grid, this defense mechanism can be described as an extremely expensive and unscientific means of defense.

However, this is the only way to deal with pirates who have landed in a swarm along the coastal horizon.

The pirates of the Sea Wolf Gang are all scattered landings, and everyone has strong combat effectiveness. And Li Zhen absolutely rejects the mode of filling with human life, using energy if you can use energy, and using knowledge if you can use knowledge. It doesn't matter if the consumption is large, what is pursued is an art of total annihilation of the enemy and no loss to our side.

According to Li Zhen's theory, the bottom of this high-voltage power grid will be wrapped with a gelatinous insulator, and the top will be exposed. This kind of grid is laid on the ground like a carpet, not a thorny steel wire mesh, which is to prevent pirates from using wooden pestles to break the grid.

The people of the entire Dafengtai are all soldiers. Defensive lines began to be arranged. Copper wires were transported to the beach on a large scale and laid from the newly built alternating current power plant in the Dafeng Terrace.

The second layer of defense is the defense on the sea.

With all the people in the army, steamers finally came in handy.

Master Wang, the royal master of the Kyushu Academy of Sciences, led a group of people to build the world's first ironclad ship.

The ship weighs 10 tons and is made entirely of steel, with a streamlined shape that comes from the Kyushu Department of Physics.

When a steam turbine is mounted on an ironclad ship, the whole ship looks like a sci-fi punk feel.

Everyone came to the beach, a little worried:

"Can this ship work?"

"Can such a heavy ship really run?"

"I think...... It's a bit of a hanging. ”

"We can't rely on the wind anymore, we have to rely on the steam turbine."

"Can a steam turbine really move this ship?"

“……”

Li Zhen stood on the beach with an indifferent face and said, "You can start." ”

"Get into the water!"

With a loud trumpet, thousands of soldiers and armor used poles to pry the ironclad ship into the sea.

With a 'bang', a huge wave hit, and the ironclad ship floated steadily on the sea. Everyone breathed a sigh of relief, such a heavy pure metal ship could really float on the sea, and it was good that it could float.

Lin Xiufeng stepped onto the ironclad ship, along with many bigwigs from the armies from all over the world, and everyone stood on the deck, watching the workers shovel the coal into the combustion chamber one by one.

There is a great deal of uncertainty in my mind.

"Pull the air plug!"

'Woo woo woo woo -'

A crazy howl came out, and a chimney on the ship suddenly spewed out thick smoke, and the sound of the whole ship could be heard by the whole Laoshan Mountain.

Slowly, the ironclad ship sailed forward, but saw that the water behind the boat seemed to be boiling, and it sprayed frantically backwards.

In the water, the propellers driven by the steam turbines rotated at super-high speeds, like an angry lion.

It just wants to hurry, a little faster.

The people standing on the deck only felt the wind coming, and when they looked back, the coast was getting farther and farther away.

"Ahh How could it be so fast. ”

"Oh my God, there are such fast ships in the world."

"This ship is five or six times faster than the warship of my Kyushu Naval Division."

"It's almost like riding a fierce horse on a plain."

"With this ironclad battleship, the Kyushu Naval Division is even invincible."

“……”

Lin Xiufeng calculated the data, a flash of excitement flashed in his eyes, and he muttered excitedly: "Streamlined, this is streamlined." The draft is deep, the speed is fast, and it all depends on fluid mechanics. I understand, I understand, hahaha, I have a deeper understanding of this fluid mechanics. ”

"The ship can be retrofitted, and it should be faster. We can build a clipper, using twin steamboats, twin propellers. Reduced wind resistance area...... It's twice as fast. It will be invincible, and in less than five years, the Kyushu Mariner will dominate the world. ”

Lin Xiufeng excitedly wrote down his inspiration in the notebook, and he felt that he probably got the inspiration for the creation of airplanes. It's a pity that Liu Jinghong is not here, if he and Liu Jinghong discuss, he may think more clearly and clearly.

Brave the wind and waves.

Kyushu's first ironclad ship went to sea, shocking the world.

The day when Kyushu sailors dominate the world is not far off.

————

The Kyushu Academy of Sciences has entered a busy state, and the whole city is full of soldiers, busy making all kinds of terrifying weapons of mass destruction.

For the first time, this group of people applied science to warfare, to killing. Only then did they realize that there was such a hearty existence in it. It's a wonderful feeling that science is being put to use.

After consulting with Li Zhen, the garrison of the Laoshan County Navy Division moved the armament depot and moved into the Kyushu Academy of Sciences. Once bitten by a snake for ten years, he was afraid of the well rope, and that group of pirates liked to rob the arsenal had to be guarded against.

In order to ensure the safety of the Kyushu Academy of Sciences, the garrison also moved a large-scale garrison into the Kyushu Academy of Sciences, which ensured the safety of the arsenal and the safety of the Kyushu Academy of Sciences.

Key units gather together to save time, effort and worry.

Time flies, Laoshan County has been completely monolithic, but the pirates have not yet come. It seems that the wind and waves have calmed down, as if the flag has died down.

But the guard did not let down. On the contrary, it is more dignified.

On this day, Li Zhen received a letter from a senior.

Walking quickly into his office, he opened the letter, but there was only one line on it:

Is there a way to kill people invisibly? The way that no one will doubt? Everyone thought that he was doing it himself, and would not suspect the way in which a third person was involved......

Li Zhen's pupils shrank: "You're going to do it?" ”

After pondering for a while, Li Zhen said to Qi Zi, "You, go and call Lin Guofu over." ”
