MTL - Online Game: Island War-Chapter 57 insidious system

After dreaming for a while, Lei Jiu suddenly remembered another thing. It seems that the R&D investment of gunpowder is also 10 gold coins per day, for a total of 500 days?

Same as the steam engine, although it can't be said to be a free gift, considering the significance of gunpowder technology, it is really worth the price of cabbage.

Although for the volunteers who boarded the ship, things like the ratio of gunpowder basically belong to the category of common sense that must be known. However, the system really only works for 500 days, with a time limit of 16 months?

Even if it takes 5 years for steel-making technology, it will take a lot of time for lathes, milling machines and other machine tools to come out, which limits the development of firearms and artillery in disguise.

However, Lei Jiu always felt unreal when he thought that he would enter the era of hot weapons in ten or twenty years.

In the face of machine guns, cannons, armor-piercing bullets for tanks, how strong the armor is?

When he thought that the lifespan of the cold weapon era was so short, his heart was a little confused, and suddenly he couldn't see the way forward or how the military road of Huanghuang Island should be taken.

No, he needs to calm down! calm!

Lei Jiu took a deep breath after walking out of the research center. It is a pity that although the sun is about to set, the air is still full of heat and dryness when one foot steps into Huanghuang Island in summer.

Compared with the heat outside, the inside of the research center was cooler, making it easier for him to calm down.

Suppressing the thought of turning around and returning, Lei Jiu planned to go back to the office.

"Master Island Master!"

"Oh, it's Li Quan, you haven't left yet?" Unlike the Tongtian Pagoda, the access threshold for the research center is very high, and now only his island owner and Nangong Di can enter.

In the future, if there are officials responsible for scientific research, they will also be granted access rights.

Obviously, Li Quan is definitely not in this list.

So, after the research center was built, he had been waiting here?

Well, although he probably only wandered around for more than half an hour, the time was not too long, but...he has something to talk to himself alone, right?

"Well, my subordinates are waiting for you, Lord Island Master!"

"What's the matter, tell me!"

"That..., um..., actually..."

"If you have something to say, just say it. Everyone is so familiar with it. What's wrong with you?"

"Actually, I have a crush on me. We plan to get married in ten days. That..."

"Marriage? Congratulations! Okay, explain the matter to your subordinates. I'll grant you three days of marriage leave!"

Now, there are no statutory rest days or holidays on the island, so the three-day marriage leave is already considered to be a mercy from the island owner, Lei Jiu.

"No, I plan to invite the island owner to participate!"

Li Quan didn't invite Lei Jiu to be the witness, because whether it was red-haired, silver-haired or black-haired, there can only be one witness at the wedding, the great creator god, no one else is qualified, but it's a little bit. The meaning of heaven and earth as evidence.

"Do you need to say this on purpose? Of course I'll go, didn't you plan to invite me?" Lei Jiu stared, looking furious.

"How come, the island owner will definitely ask, I'm not doing this right now!"

"Yeah~!" Lei Jiu nodded with satisfaction, then patted Li Quan on the shoulder, "That's it, it's almost time for dinner, let's go together!"

The location of the R&D center is not far from the Tongtian Tower. In fact, Lei Jiu plans to build all the system buildings that do not occupy a large area here, so it is more convenient to put them together.

From here, to his island owner's office, this section will be the political center of Huanghuang Island in the future.

After dinner, it was completely dark. There was a kettle on the small stove in the backyard of the office. Lei Jiu, Nangong Ding, and Luo Zheng sat around the small stone table, with teacups and teapots in front of them.

Although there were only teapots and cups but no tea, the three of them still stared at the kettle on the small stove, waiting for it to open.

As long as the water boils, our Frost Mage, Nangong Di, can cast real magic and make it instantly cool and white.

Then, the three of them can quench their thirst. By the way, isn't today's dinner particularly salty? Why do you feel so thirsty?

When it comes to salty, it is necessary to talk about the salt that the human body must consume daily. In the world with islands all over the world, there is absolutely no shortage of materials for drying salt, and there is no technical barrier in the system for drying and removing impurities in seawater. Huanghuang Island has its own salt field.

But in view of the current land use situation, the scale of this salt field is so small that Lei Jiu is too embarrassed to call it a salt field.

In fact, cooking on the island now hardly uses salt.

Dundun only eats sea fish, what kind of salt do you put in, will you die?

It's just that a little bit may be added when drying the dried fish.

So right now, the demand for salt on the island is really not high, and the poor output of the salt farm is barely enough.

Perhaps the gazes of the three of them were too scorching hot, they boiled the water that was about to boil, and there was already thick steam rising slowly at the spout.

After waiting for a while, when the water was fully boiled, Luo Zheng stepped forward and lifted the kettle.

"and many more!"

Lei Jiu suddenly interrupted Luo Zheng, frowning, staring at the red coals burning on the stove.

"This pot of water, I'm sure I'm very full!"

Luo Zheng tilted his head suspiciously, staring at his own island owner, what are you trying to say? Nangong's magic is all ready, what's the matter?

Nangong Di also looked at Lei Jiu, not understanding what he was trying to express!

Seeing the doubts on their faces, Lei Jiu wondered, "No, won't the water boil violently? Especially when the stove is very hot and the water is full, the lid of the pot will be jumped up and down by the steam top. , the spout will also make a hissing sound due to the violent ejection of steam!"

"Who said that? Patriarch, are you sick?" Luo Zheng obviously felt sick when Lei Jiu started talking nonsense. He felt a little anxious for a while, and the title Patriarch came up again.

"Hey?"

Looking at Luo Zheng's concerned eyes, and then at Nangong Ding's searching eyes, Lei Jiu was silent!

Hey? What's going on?

Am I really sick?

Shouldn't the lid be lifted when the water is boiling?

Wasn't the steam engine born out of this inspiration?

"Cough, UU reading www.uukanshu.com that, Nangong, have your mages studied the volume change caused by the transformation of the physical state?" Lei Jiu intends to understand it from a scientific point of view.

"Of course there is! Take water, for example. Under standard atmospheric pressure, ice at 0 degrees is nearly 1.1 times the volume of water of the same mass."

Nangong Di's answer made him stunned, let me stop him, are all mages so good? The standard atmospheric pressure is all set.

However, this is better.

"Then, do you know, at standard atmospheric pressure, at 100 degrees, how much water vapor will 1 cubic meter of water become?"

"nature!"

That's fine, "How big is it?"

"3 cubic meters."

"A lot, how much?" Isn't it 1557 cubic meters?

"3 cubic meters! Lord Islander, is there a problem?"

"you sure?"

"Yes, I'm very sure, otherwise, call out the nicotine master. The masters of this basic knowledge should know, even the prehistoric ones."

"Ah! No, he has been playing crazy in the Tongtian Tower for the past two days, and now he is recovering in the magic lamp. Sorry, Nangong, it's not that I don't believe you, I'm just a little too shocked!"

More than shocking, he was about to yell at me!

1 cubic meter of water, the volume of water vapor after boiling is only 3 cubic meters? Directly shrunk by more than 500 times, this volume expansion ratio, and a hammer steam engine?

System, you are too insidious to change the rules of the world quietly?
