Starting Today, I'll Work as a City Lord.

The most famous of these is the Tianjian series of sniper crossbows. Now there is the first generation of Tianjian No. [-] sniper crossbow, which is transformed from a bed crossbow. It is used for sky-to-ground sniper killing and will be installed on sky fortresses in the future. The enemy's weapon, that is, the airship.

It is made of all fine steel, and a two-meter-long spear is used as a crossbow arrow. When shot out, it can tear several horses apart, and even the horse can fly.

In addition to Tianjian No. [-], there is also Tianjian No. [-] in an ideal state, that is, No. [-] under design, with a dense arrow array on the ground, throwing spears from high altitude, and accelerating the spears to kill the enemy through gravity. Sprinkle it once over densely packed enemies, nailing people and horses to the ground.

The scientific research department is working on weapons like this, mainly because Liu Feng provided ideas. He has watched a lot of anime, so he modifies them according to some of the ideas in the anime.

Gunpowder can be used or not. Cold weapons are the best way to solve the problem. After all, cold weapons alone are no longer his opponents. He doesn't want to start a war with hot weapons too early. There are too few people and too few mouths. , Can't stand the toss of gunpowder.

"Can you give me a hand? I want to kill that dragon." Leia stepped forward emotionally.

"It can't be carried by one person." Liu Feng shook his head, the Tianjian series are heavy and big, at least it takes several people to carry them.

For large prey, he is really not afraid at all, there are too many ways to deal with it, the premise is that he is prepared.

He asked people to study the Tianjian series, mainly to prepare for going to sea in the future. There are many huge monsters in the ocean, and there are some ships. As long as a few sticks are attached to the wall of the ship, the ship can completely sink in the water.

"I can let a few people carry it." Leiya said quickly.

"No, there is a better way to kill the dragon." Liu Feng shook his head, using the Tianjian No. [-] sniper crossbow, maybe he could kill the dinosaur.

But the Tianjian No. [-] sniper crossbow is still being modified, and some redundant components have been removed, so it can't be put into actual combat.

"What way?" Leia asked eagerly.

"Use a large military crossbow. Three people can use it. Two people carry it, and you operate it alone. With a strong anesthetic, it can completely bring down the dragon." Liu Feng said lightly.

This method needs to be grinded slowly, and then after the dinosaur is brought down, find a way to kill it.

"What is an anesthetic?" Leia wondered, it was the first time she had heard of this thing.

"Pharmaceuticals that can make people faint and immobile." Liu Feng said lightly, as long as the strong anesthetic is enough, it can completely bring down a dinosaur.

"Really?" Leia's green eyes lit up.

"Of course, this time you take someone out to help me get some things from the volcano. You can also investigate the situation. I will allow you to bring weapons next time." Liu Feng said lightly.

"Okay." Leia agreed.

Chapter 0740 new alloy?

At twelve o'clock at night, the Sky Fortress Research Institute of the Scientific Research Department is brightly lit.

At this time, the dwarf Yuffie was still working, wearing linen clothes, and the little man was staring at the stove. His previously delicate face was now covered with dust, and he looked as if he hadn't bathed for a few days.

"This time the ratio should be fine." Yuffie's pink eyes were full of light, she clasped her hands in front of her chest, and muttered, "It must be possible, it must be possible."

After she went shopping with An Li and the others today, she immediately returned to the research institute. She hadn't left the research institute for the past three or four days. If An Li hadn't come to look for her, she would have stayed here to study successfully, and she would study until two or three nights every day. point.

That's it, when Liu Feng knew about it, he ordered Fox Erniang to go shopping in La Youfei, so that she could have a little rest.

I went out to play around today, and came back with a glimmer of inspiration, and immediately researched it according to the alloy ideas provided by Liu Feng.

Air fortresses, that is, airships, need very light materials, so that they can fly high, and the danger will be greatly reduced. If iron is used as the material of the airship, it will be difficult to fly alone, and the volume will also be large.

Liu Feng can provide some alloy formulas, but he can't get the ones that are too confidential. He can only get some popular alloy formulas, such as lead alloys, copper alloys... and so on.

And some alloys are made with the technology of this era, so don't think about it, it still needs a large amount.

In particular, some ores have not been found yet. Not all ores are located around Xiyang City. The ores used by the research institute are all transported from other places.

Liu Feng has reached cooperation with the major city lords and nobles, including ore transactions. Each lord will collect some ore and transport it to Xiyang City.

Now most of the ore is sent to Yuffie, and she requested it herself. She wants to make a very light alloy, so that she can fly to the Aoli dwarf kingdom in one go.

"Huhuhu..."

Yuffie quickly increased the firepower, then threw a few pieces of coal into the stove, looking at the three ores of different sizes that had been slowly melting.

I don't know the name of these ores, they are all newly shipped, there is no iron ore in them, she found that if iron ore is used as the raw material of the formula, the weight will generally not decrease, but the volume will shrink instead.

"Molten!" Yuffie shouted excitedly, her pink eyes filled with anticipation.

She has experimented hundreds of times, at the beginning of random experiments, and occasionally experimented with new alloys that are large in size, high in hardness, and light in weight.

Then she slowly experimented with the proportions of the three alloys according to the alloy she obtained by chance. The more she experimented, she found that the hardness was getting harder and the weight was getting lighter, which made her very excited.

"It must be possible." Yuffie's gray face, under the light of the stove, made people feel like a faithful believer.

"It's all melted." After Yuffie saw that the three pieces of iron ore were all melted, he immediately took the refined steel rods on the side and stirred them, and then went through a few more steps...

Time slowly came to one o'clock at night, and Yuffie poured out the molten alloy material to cool and solidify.

Another half an hour passed, and Yuffie got a piece of gray alloy. Holding the alloy, she suppressed her emotions and began to take the test.

Holding the alloy, she scanned the ground for ores and discarded alloys, and immediately found a steel of about the same size, and immediately carried it to the workbench.

"Weigh it first." Yuffie skillfully took a scale, immediately began to weigh it, and started writing in a notepad.

"Great, it's four times lighter than fine steel." Yuffie shouted excitedly, at this time she got the lightest alloy.

"The next step is to test the hardness of the two." Yuffie collided with the two alloys.

"Clang clang..."

The sound of metal clashing was heard far away in the middle of the night, causing the soldiers patrolling outside to shake their heads in admiration of the little girl's madness.

"Hahaha... the hardness is also harder than fine steel, which is great, could it be a success?" Yuffie was stunned, staring blankly at the new alloy in her hand.
