I run a farm in another world

Chapter 201

After learning how to play boomerang, these people left one after another to show off in front of their friends.

The boomerangs also sold out very quickly. In a short time, more than 500 boomerangs were sold out. This was all the carpenters at home had made in the past few days.

Those who didn't buy it were secretly annoyed and regretted missing Du Wenkai's "starter", so people began to buy it at a high price. In just half a day, the price of the boomerang more than doubled by more than ten times.

After selling the boomerangs, Du Wenkai went back. Although they were sold very quickly, the total price was only five hundred silver coins, and it would be far more than this amount to cultivate a strange flower by himself.

He mainly opened up a market for the family and made the boomerang an industry of the family.There are hundreds of thousands of residents in Donghai City, so it is not a problem to sell it for [-] yuan, and this thing is just a piece of wood, which is easily damaged.

Moreover, the family has trade relations with Mote City and Nanyang City. When the time comes, this thing will be labeled by the family and sold to major cities.

"Next, I want to study how to make those people build telescopes faster." Du Wenkai started a new plan.

······
At the East China Sea Auction, Qin Han took a boomerang and looked at it carefully for a while.

"Do you know how this thing can be thrown out and then flew back?" Qin Han put the boomerang on the table and asked the butler in front of him.

"This subordinate doesn't know." The butler bowed deeply and said with a wry smile.When the boomerang first went on sale, he ordered someone to buy one from Du Wenkai.

He also studied it carefully himself, but he still couldn't see through the doorway above it. He didn't understand why it looked like an ordinary piece of wood, and why it had the effect of being thrown back and flying back.

"Frankly speaking, I don't know either." Qin Han was speechless for a while. When he was in the hot air balloon, he could still see some tricks.When the air is heated it becomes so light that it floats up, just as wood floats on water and iron sinks.

But after seeing the boomerang, he was completely stunned, unable to understand the principle of this thing at all.

"This fourth young master of the Du family is really a magical guy." Qin Han smiled half-heartedly, "In the future, pay more attention to the movements of the Du family. Maybe this young master will continue to provide us with some surprises."

Of course, Qin Han didn't expect that after a few days, something even more surprising appeared.

······
"Crack!" Ling Lei crushed the teacup in his hand, with an angry expression on his face.Originally, Du Fu was completely suppressed from the exotic flower business, and he was a little complacent. As a result, he had no plan to fight him in this aspect at all, but instead found another shortcut to develop the family business in other aspects.

Judging from the popularity of Boomerang, it will become a very important industry for the Du family in the future, and it can also go out of Donghai City and easily move into other cities.

There was a boomerang on the table in front of him, and Ling Lei played with it carefully. In addition, he also bought a hot air balloon at a high price.

"How did this kid make these things?" Ling Lei thought about it but couldn't figure it out. If Du Wenkai's super fast cultivation speed and super high success rate of cultivating strange flowers all depended on that ninth-level monster What about the hot air balloon and boomerang?

It is absolutely impossible for this thing to be made by a ninth-level monster, not to mention that when the hot air balloon appeared, that kid Du Wenkai hadn't known the ninth-level monster yet.

Ling Lei would never have imagined that these things are all products of the 21st century. If it were not limited by his own knowledge level, Du Wenkai could make more magical things.

"No matter what, my goal will not change. I must continue to suppress the Du Mansion, so that I can complete my plan as soon as possible." Ling Lei secretly made up his mind that as long as he can get the ninth-level monster, no matter how much he pays. worth it.

······
Du Wenkai took the telescope lenses polished by those carpenters and looked at them again and again. Some of these lenses had uneven surfaces, and some had many scratches, which could not be used as telescope lenses at all.

"Could it be that I am the only one who can make this thing?" Du Wenkai was speechless for a while, if that was the case, it would be better to cultivate two more exotic flowers.

No matter how rare and profitable the telescope is, it is absolutely impossible to compare with the exotic flower, so Du Wenkai will never waste his time to make this thing on a large scale.

Suddenly, Du Wenkai slapped his forehead and said: "Oh, why am I so stupid, I am not the only one who has fighting spirit, I can definitely find those warriors."

As soon as he thought of it, Du Wenkai pulled Du Wenying, Chen Junhao, Du Chun and Du Hao over.

"Hey, what are you bringing us here for?" Du Wenying asked first.

"Teach you how to make telescope lenses." Du Wenkai said, "I want telescopes to become an industry in the family just like boomerangs. In your spare time, you can polish and polish the lenses with fighting spirit to make telescopes."

People like Chen Junhao need an additional salary increase, but the direct children of Du Wenying and his family, for the sake of the family's development, naturally do their part.

"Why, let us be coolies?" Du Wenying curled her lips, a little dissatisfied.

"Those lenses polished by ordinary people can't be used at all, so they need to be polished by warriors with fighting spirit. You should be able to see that the gardener named Ling Lei is targeting our family intentionally or unintentionally, so for the development and continuation of the family, Each of us has to do our part." Du Wenkai said solemnly.

Hearing this, Du Wenying didn't continue to complain, and Du Hao and Du Chun both nodded.

Then, Du Wenkai turned to Chen Junhao and said, "Brother Chen, don't worry, we won't let you work for nothing, and we will pay you another salary according to the qualified lenses."

"You're welcome, Fourth Young Master." Chen Junhao smiled naively.

"Okay, now let's take a look at the lens of the telescope." As he said, Du Wenkai took out the lens of the monocular in his hand, a concave lens and a convex lens.

"One is concave inward, and the other is convex outward, and try to keep their curvature at a glance, otherwise it will be very awkward to force them together." Du Wenkai began to explain.

He thought about it. With the level of these people, it is very difficult to create a concave lens and a convex lens with the same curvature, but there is another way.

Just put all the lenses they made together. As long as the quantity is large, it is not difficult to find ones with similar curvatures, and you can also put them together with similar magnifications to make binoculars.
