Online Game: Island War

After having a sweet dream for a while, Lei Jiu suddenly remembered something again. It seems that the investment in research and development of gunpowder is also 10 gold coins per day, a total of 500 days?

The same as the steam engine, although it cannot be said to be free, but considering the significance of gunpowder technology, it is really cheap.

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

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

However, Lei Jiu always had a sense of unreality when he thought that he would really enter the era of hot weapons within ten or twenty years.

In the face of machine guns and cannons, armor-piercing bullets for tanks, so what if the armor is made stronger?

Thinking of how short lifespan was in the cold weapon era, his heart was a little confused, and suddenly he couldn't see the way ahead, how to take the military road of Huanghuang Island.

No, he needs to calm down! calm!

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

Compared with the hot air outside, the inside of the research center was cooler and it was easier for him to cool down.

Suppressing the thought of turning back, 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 Tower, the research center has a very high entry threshold, and now only he, the island owner, and Nangong Chen can enter.

In the future, if there are officials in charge of scientific research, they will also be given access rights.

Obviously, Li Quan is definitely not on this list.

So, before the research center was built, he has been waiting here?

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

"Well, this subordinate is waiting for you, Lord Island Master!"

"What's the matter, tell me!"

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

"Just speak up if you have something to say, everyone is so familiar, what's wrong with you?"

"Actually, I have someone I like. We plan to get married in ten days. That..."

"Married? Congratulations! Okay, explain the matter clearly to my subordinates, and I will grant you three days of marriage leave!"

Right now, there are no such things as statutory rest days and holidays on the island, so the three-day wedding leave is considered a great mercy of Lei Jiu, the island owner.

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

Li Quan did not invite Lei Jiu to be a witness, because no matter if it is red-haired, silver-haired or black-haired, there can only be one witness for the wedding. The meaning of heaven and earth as evidence.

"Do you have to say it on purpose? Of course I will go. Don't tell me you haven't planned to invite me?" Lei Jiu stared, trying to get angry.

"How come, the island owner must invite you, I'm not doing this right now!"

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

The location of the research and development 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, and it is more convenient to put them together.

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

After dinner, it was completely dark, the backyard of the office,

There was a kettle on the small stove, Lei Jiu, Nangong Yu, 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 all the time.

As long as the water boils, our ice mage Nangong Fen can cast real magic, making 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, we have to talk about the salt that the human body must ingest daily. In a world full of islands, there is absolutely no shortage of materials for drying salt, and the system does not have any technical barriers to drying sea salt and removing impurities. Huanghuang Island has its own salt farm.

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

In fact, cooking on the island does not use much salt.

You only eat sea fish, why do you put any salt, will you die?

It's just that when the fish is dried, it may add a little bit.

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

Perhaps it was because the gazes of the three of them were too hot that they boiled the water that was about to boil, and thick water vapor slowly rose from the spout.

After waiting for a while, when the water was fully boiled, Luo Zheng was about to step forward and lift the kettle.

"etc!"

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

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

Luo Zheng tilted his head in doubt, staring at his island owner, what on earth are you trying to say? Nangong's magic is all ready, what can we say when we are full?

Nangong Qi also looked at Lei Jiu, not understanding what he wanted to express!

Seeing the doubts on the faces of both of them, Lei Jiu wondered, "No, wouldn't the water boil violently after boiling? Especially when the stove is very hot and the water is full, the lid of the pot will bounce up and down on the top of the steam. , 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 a little anxious when Lei Jiu started talking nonsense, maybe he was sick, and the title patriarch popped up again.

"Why?"

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

Why? What's going on?

Am I really sick?

Shouldn't the lid be lifted when the water boils?

Wasn't the steam engine born from this inspiration?

"Hey, that, Nangong, have you masters studied the volume change caused by the transformation of the state of matter?" Lei Jiu intends to understand it from a scientific point of view.

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

Nangong Yu's answer made him dumbfounded, I'll fuck it up, are mages all this powerful? The standard atmospheric pressure is adjusted.

However, it is easier to do this way.

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

"nature!"

That's good, "how big?"

"3 cubic meters."

"How much, how much?", isn't it 1557 cubic meters?

"3 cubic meters! My lord, do you have any questions?"

"you sure?"

"Yes, I'm very sure, otherwise, call out the great mage Nicotine. All mages should know this basic knowledge, even if it is prehistoric."

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

Not only was he shocked, he was about to yell at me and fuck me!

1 cubic meter of water, the volume of water vapor after boiling is only 3 cubic meters? It has been directly reduced by more than 500 times, with this volume expansion ratio, and a steam engine with a hammer?

System, you are too insidious to change the rules of the world without making a sound?
