Chapter 226 Chapter 225 Stranded

Some cicada monkeys live underground for one or two years, some for three to five years, and even more than ten years, and then emerge from the ground to metamorphose, completing their missions of mating and laying eggs in one summer, and entering the next reincarnation.

Cicada monkeys that grow in the land of China are eaten and farmed to reproduce, as are grasshoppers, scorpions, crayfish, etc., which is a bit embarrassing for the insect race.

The unbroken cicada monkey has the highest protein content and is also the most delicious. Once the shell is broken, the taste will be greatly reduced. When it transforms into a cicada, the tail will be basically empty, and only the wings will still have some meat.

Due to night blindness and the lack of popular flashlights, not many people come out to touch monkeys at night.

Some children like to go to the grove early in the morning to pick up cicada sloughs. These are Chinese medicinal materials that can be sold for candy.

Some children choose to make glutinous rice during the day. They put a handful of wheat in their mouths and chew it repeatedly. After chewing it into a thick paste, they put it in water and rub it to remove the bran. The sticky wheat glue is ready, and the wheat glue is ready. Put the glue on the long bamboo pole, hold your head high, follow the hoarse cry of the cicada to find the target, and slowly bring the glue closer to the cicada. Once it sticks, the cicada cannot run away.

Tang Zhitong doesn't plan to take classmate Xiao Wang to cicadas. This kind of activity is too taxing...

Since it was not yet the peak time for the cicada monkeys to be unearthed, after more than an hour, the flashlight ran out of power and I couldn’t touch many cicada monkeys. However, Xiao Wang had a great time playing. After all, he was only 18 years old. Half a young girl...

The most delicious way to eat cicada monkeys is deep-frying or frying. A few of them cannot be eaten. Tang Zhitong used the space to scan the ground and decided to let the cicada monkeys develop for a few more days and then harvest them when they are at their most plump. It tastes better.

When they went home in the evening, the two did a deep body cleansing. When they were reviewing old knowledge before going to bed, Tang Zhitong found that classmate Xiao Wang's hair was not dry.

No wonder most married women choose short hair. They already have a lot of housework after get off work, and washing their hair is difficult and delays things.

Tang Zhitong had seen a large hair dryer in a barber shop, which looked like alien technology. There was no small hair dryer in it, not even in the Wangfujing Department Store.

Tang Zhitong wanted to try out a handheld hair dryer. The market for this thing is huge.

When he went to work the next day, Tang Zhitong didn't forget to bring eggs to Wan Xiangyang. There were twenty eggs, so he saved some to eat until the end of the college entrance examination.

"Brother Yang, go back and marinate some of it and eat it slowly." Of course the eggs are in the space, but it's hot now, so it's enough to leave them at room temperature for about ten days. If you leave them any longer, they will probably go bad.

"No more words, thank you!" Wan Xiangyang didn't expect Tang Zhitong to give so much at once. Now he can't even buy chickens, let alone eggs? Even if it occasionally exists, it is not something ordinary people can buy or afford.

"You're welcome, I wish you a good name on the red gold list." Adding icing on the cake is not as good as giving someone timely help. The purchase price of these two kilograms of eggs is only one yuan a piece. It can save a piece of college students' love, which is very valuable.

As for how much eggs can be sold for on the market now, Tang Zhitong hasn't paid much attention, and he thinks they are definitely not cheap.

Hospitals have begun to subsidize meat for blood donation. I guess only if there are people in the family who need nutrition and the allocated meat tickets are not enough, the family members will donate blood for meat, right? This is similar to donating blood in exchange for school district points...

After saying goodbye to Wan Xiangyang, Tang Zhitong went to Fangyuan's office, but Fangyuan was not there again.

Tang Zhitong didn't have his own office, or even his own desk. He had to make do with Fangyuan first.

Using the work paper, Tang Zhitong used a pencil to write ideas and plans on it.

The simplest hair dryer consists of a motor, a fan, a heating wire, a switch, and a casing. The core components are the motor and the fan.

There are two types of motors: brushless motors and brushed motors. The prototypes have been out for many years, and the general principles can be found in the physics textbooks I learned before. Forget about brushless motors. This thing requires a circuit to control the magnetic coil. It cannot be miniaturized for the time being. The main direction is to use brushed motors.

The brush motor has a simple structure and can be circumvented by experts at home. When Tang Zhitong was a child, there was a cartoon called "4WD Boy". At that time, the streets were full of boys playing with four-wheel drive vehicles.

Tang Zhitong begged his grandfather to sue his grandmother. Fortunately, he had one. After playing with it for a short time, it broke. He cried and fussed over it and refused to buy it. This made him depressed for a long time.

Later, a sun hat with a fan appeared on the market.

This kind of hat has a fan and battery on the front, so it is easy to sink forward, and the wearing effect is not ideal.

Tang Zhitong's classmate at the time had one. After showing it off for a few days, he found it was not practical and left it idle.

Tang Zhitong used a few pieces of candy in exchange for the fan on his hat, because he found that this thing was similar to the motor on his four-wheel drive!

In this way, Tang Zhitong successfully repaired the four-wheel drive vehicle, and the broken motor was not wasted. He pried it open and observed it, which was his first attempt to understand the motor.

Tang Zhitong knew the appearance of various handheld hair dryers, but he didn't know the internal structure.

When I was a kid, I liked to take it apart and look at the parts. When I got older, I liked to take it apart and touch the parts... these are two different things.

Although Tang Zhitong had never studied fluid mechanics or aerodynamics, he probably knew what type of fans had strong wind power, and even what types of submarine propellers he had seen, but the motor was blind.

At a voltage of 220V, should the heating wire and motor be connected in series or in parallel? Does the motor require a transformer? What type of magnets and copper wires can meet the requirements? How many circles do you have to go around?

Why haven't I seen a small one? Is the motor miniaturization technology immature? What are the key points inside? His eyes went dark...

When he actually wrote the plan, Tang Zhitong discovered that inventing such things, especially industrial products, was much more difficult than when he imagined it.

At this moment, Tang Zhitong even envied those protagonists who had systems, workshops and other things. They could just do whatever they wanted to produce. It was so easy, unlike him who had been tired for most of the day and couldn't get out...

There were too many difficulties in front of him, so Tang Zhitong planned to put it on hold for the time being. When he had the opportunity, he would first go to Jiaodian Sales Department to see if there were no suitable raw materials there.

If that still doesn't work, take the opportunity to take a letter of introduction to the electrical machine factory.

If there is really no other way, just wait until school starts. If students have any questions, they can always ask the teacher, right? It’s not like my employer didn’t help me pay my tuition!

The reason is that you must tell the truth to your own people, and it is not wrong to love your wife.

If you speak to the public, you must have a noble and high-sounding reason, such as: caring for the health of female compatriots so that they don’t catch cold after blowing in the morning; contributing to improving the spiritual outlook of women; using this kind of sugar-coated cannonball to attack the evil imperialism, and for The country earns foreign exchange and so on.

Which one to use will depend on the situation.
