PS: I'm sorry, I went on a business trip yesterday, and I dealt with more urgent things at the end of the year, and I didn't even bring a computer, the first update.

On the earth, the great development of agriculture is inseparable from machinery, among which the most widely used is not a seeder, nor a harvester, but a pump.

In terms of agricultural planting, the decisive influencing factor, first of all, moisture, rain is not good to interfere, even with greenhouses, continuous rain will cause a variety of viral infections of plants.

As for seeds, fertilizers, and pesticides, this is actually arranged behind the water, no matter how good the seeds are, in the event of drought, the buds will not come out, and the fertilizers will not work without water.

The advent of pumping machines has added a safety rope to agricultural planting.

The steam engine pumped water, Luo Heng decided to use mature technology, in fact, as long as the height of the pumping machine is not too high, then the cost of the flat spread is very low.

Kuisen led people to follow Luo Heng to the valley behind the territory, which was the safest place, because this was the territory of the Giant Ranch.

For giants, there will be no threatening creatures in their territory, not even dragons.

Quison looked at the huge metal machinery that was more than one person tall, and immediately judged that this was an ordinary machine.

A dam has been built with stones under the valley, after all, this is a pasture in the future, and the water source of the pasture is also the first, and the installation of a pumping machine here is also a service for the pasture here, pumping water in times of drought.

Luo Heng opened his mouth and said, "Let's add water first." ”

The water in this pumping machine designed by Luo Heng is recycled, and the steam is cooled directly in the dam with pipes.

The advantage of this is that it takes less time to replenish water and is easy to operate.

Of course, it's not very complicated to manufacture, it's just some valves.

Of course, the pressure gauge was wanted, Luo Heng commanded the two giants to directly use a large wooden barrel to draw water, and Luo Heng lit the fire on the side.

"It took a long time to start. Luo Heng said.

Wood starts with dry wood, then semi-dry, and wood that is too dry burns too quickly.

It took nearly an hour for the pressure to be almost reached.

Luo Hengyou commanded the giant's other water pump to fill and divert water, and then opened the valve.

The powerful steam pressure began to push the pistons, which drove the huge flywheel, and between the flywheel and the pump, the world replaced it with a similar gear.

Woooooooooooooooo

After the flywheel reached a certain speed, Luo Heng directly pushed the gear of the water pump up.

All of a sudden, the pump whined.

"Look over there. Luo Heng pointed to the hillside hundreds of meters away, and soon a column of water erupted out.

The magician beside Quisen's eyes lit up, and even Quisen's eyes lit up.

Why didn't Luo Heng sell the steam engine pump himself?

Because it's difficult, because local protectionism here is too strong.

Quison scanned it with his mental power, and after half an hour, Quison understood the principle.

"Cheney, only you dwarves can build such a sophisticated metal machine. Quison exclaimed.

Don't underestimate this steam pump, just this steam pressure tank, the average blacksmith really has no choice.

The other is the bearing, the bearing used on the pump, which is also not made by ordinary blacksmiths.

"Cheney, how about weaving and spinning thread?"

"Brother Quison, I've thought that too, but this will bankrupt a lot of civilians, so the steam engine must be limited to other things. Luo Heng said.

Hearing this, Quisen nodded and said: "Those nobles are vampires, I agree with you, don't worry, this steam engine is in our Wizards Association, and no one dares to use it without permission." ”

"Brother Quisen, I only authorize the authorization of the steam engine to the pump, and Brother Quisen, I think that the Magician Guild and the dwarf kingdom can unite with the dwarf kingdom and establish a water pump association, we can set up pumps all over the world, and then charge according to the pumping time, otherwise such a pump is in the hands of those noble lords, I am afraid that it will be charged harshly." Luo Heng said.

When Quison heard this, he pondered for a moment, and then asked, "How much area can this pumping machine cover?"

"One thousand acres is no problem, if a reservoir can be built at a high place, then three or five thousand acres is also possible. Luo Heng said.

Luo Heng saw on the earth that in some mountainous areas, just dig a few mountain ponds, and a pumping machine can cover a large area.

"The amount of money involved is huge. Quison pondered for a moment and spoke.

"The benefits are also very considerable, and as long as this thing is well protected, then there is no problem with twenty or thirty years. Luo Heng said.

Quisen nodded: "Okay, I'll send a determined team over, and the Pump Association is also a good suggestion." ”

"And the profitability of the Pump Association is one thing, and the other is word of mouth. Luo Heng said.

"Cheney, why don't you start an agricultural association with pesticides?" asked Quison.

Luo Heng shook his head and said: "Don't, many civilians have no knowledge at all, making pesticides is making poisons, there will be some people who can't figure it out." ”

When Kuisen heard this, he didn't say anything, and Luo Heng made it very clear that civilians would be very afraid of the water pump.

In fact, according to Luo Heng, this is a fool, pesticides themselves are poisons, some people drink pesticides and die, and some people actually scold the ...... who study pesticides.

The Wizards' Guild has a strict evaluation body, and there are very few that can register intellectual property rights in the Wizards' Guild.

"Cheney, you know what, you changed our thinking. Quison said as he watched the water jet from the pump.

"What kind of thinking?" Luo Heng asked curiously.

"In the past, magicians have set their sights on the field of magic, but you also know that magic experiments and magic research are very costly, and the things you have come up with in the last two years are actually not very esoteric principles, but each one has been a great success, and the method of white sugar purification is actually much simpler than the purification method in potions, but the white sugar purification method has been quickly promoted. There are also seeders, harvesters, threshers, flour grinders, etc., the principle is not very complicated, but the income brought to you by these things is very considerable, even the most demanding magicians, think that you are successful, and now some magicians have also turned to study your kind of things. Quison spoke.

"Is this okay?" Luo Heng asked.

"Of course it's good, but from the yarn to the sweater to the pump, I knew that no one else could make it. Quison spoke.

"How did you come up with this steam engine?" asked Quison.
