Chapter 7 Winning the Prize

As he was thinking, Gao Zhendong started to feel drunk and had a good sleep. When he woke up, it was almost time for lunch.

Gao Zhendong washed his face, rinsed his mouth with the boiled water he had boiled at noon, bought a handful of noodles, a sausage, and a cabbage, took out half a bottle of chili oil from the storage, and had a simple meal of noodles.

After eating and drinking, Gao Zhendong took out paper, pen and tools and started to draw. Yes, he was drawing the blueprint of the return air furnace in his previous life. He saw this thing at his grandfather's house when he went back to his hometown during the Spring Festival in his previous life. He felt it was very novel at the time and studied it carefully, so he remembered the structure very clearly.

The return air furnace is less common in the future cities, but it is still very common in small towns and rural areas. Based on the early iron furnace, the furnace adopts the principle of return air circulation heating to recycle the residual heat energy in the flue gas and reduce coal consumption through secondary combustion.

The advantage of this thing is that it is easy to use, simple to operate, and does not require tedious maintenance and cleaning. It is suitable for use in rural areas and small towns. It has high thermal efficiency and can save a lot of coal for the same amount of heating.

The disadvantage is also very direct, expensive! Whether it is materials or labor hours, the requirements of this thing are much higher than those of the old iron stove.

But Gao Zhendong is not worried about this. He is not selling it, but using it himself. He can afford the higher price. As for the factory or other units that think it is good and want to produce it according to the drawing and sell it, they don’t have to worry about the sales. This thing is not too expensive. For its benefits, ordinary people can still afford it if they grit their teeth.

Gao Zhendong had learned mechanical drawing quite well in his two lives. While recalling the details of each part, studying the parts that were vaguely remembered, and calculating the dimensions, he finally finished the drawing around ten o'clock in the evening.

He gave himself a thumbs up in his heart, put away the drawings, and went to sleep.

The next day, Gao Zhendong packed up and went out, carrying a big bag, and went straight to the supply and marketing cooperative.

When he arrived at the supply and marketing cooperative, Gao Zhendong bought a lot of daily necessities and then went on to buy some grain, oil and other non-staple foods.

When passing by a consignment store, Gao Zhendong saw a broken "Peony" brand six-tube radio, which was priced at 50. This is a good thing, a new one costs more than 100, and you need a ticket, which is inconvenient to buy.

Suddenly, Gao Zhendong's soul as a junkman in his previous life awakened, "I'm determined to chop this hand off!!!" Thinking of the loss of money in gambling on electronic waste in his previous life, he burst into tears.

He decided to go all out, so he wandered around the store for a while and spent another 45 yuan to buy a May Day watch from the Tianjin May Day Watch Factory, the predecessor of the future famous "Seagull".

This watch is one of the first batch of precision industrial products made by ourselves after the founding of the People's Republic of China. It is not particularly accurate, but if you check the watch regularly with the factory's timekeeping, you can tell whether it can be used. The key is not to have a ticket. Some people say that the calendar can also be explained clearly.

The morning passed like this. Gao Zhendong sent the things home and went out to have a good meal at the state-owned restaurant.

Gao Zhendong's plan for the afternoon was to buy big items. He wandered around the consignment store, coal station, and scrap collection station for the whole afternoon. He basically bought all the furniture and coal briquettes, and also bought a tin bucket for a few cents at the scrap station.

He spent some money to hire someone to deliver the things back home. On the way, Gao Zhendong borrowed a hoe from someone else and dug some yellow mud on the roadside.

After the things were transported back home, Gao Zhendong told the movers to put the furniture away. The walls of the house were still intact, and after the Third Uncle's family cleaned it up, it looked pretty clean. Gao Zhendong decided not to paint the walls, and would think about it after the wedding. If he painted the walls once now and had to paint them again after the wedding, wouldn't the walls have been painted in vain? While the workers were putting the furniture away, Gao Zhendong went to the Third Uncle's house to return the coal briquettes, and then came back to smooth things over. Don't get me wrong, he just wanted to use that tin bucket to make a stove.

Considering that he would need a return air furnace in the future, Gao Zhendong decided not to use the south room as a kitchen for the time being. He would burn the return air furnace in the corner of the living room and use it as a kitchen, which would save some coal in winter. Summer? In summer, he would move the furnace to the south room.

Before the return air furnace was completed, Gao Zhendong planned to use this iron barrel stove for a while. He thought the stove in the living room took up too much space, so he asked workers to knock it all down. As a bachelor, he was so casual. The bricks and stones that were knocked down were not wasted and were used to reinforce the outdoor pool and kang stove.

This iron bucket stove will be phased out in the future, but it can be used occasionally for emergencies. When Gao Zhendong was at the coal station, he had already seen honeycomb coal, so he made one according to the style of the honeycomb coal stove in his previous life and combined it with the current size of honeycomb coal. As for the problem of yellow mud's mediocre fire resistance and durability, he was not going to solve it, anyway, he would just use it for a while.

Time passed in a busy manner. He bought some food for dinner and asked Sha Zhu to cook it at the Central Courtyard. He then invited the workers who had been busy all afternoon to have a meal together.

Sha Zhu also laughed and joked: "Brother, it would be great if you cleaned the house every day."

On that day, Gao Zhendong met the thief Bang Geng and her older sister, two little brats, who were about the same age as Sha Zhu to join in the fun. Gao Zhendong grabbed a few Cuban candies for them, and the two kids were happy for a long time. Although Bang Geng's character in the original TV series was really unpleasant, it was not obvious now. Gao Zhendong really couldn't care about a little brat for this reason that others couldn't understand.

In the blink of an eye, it was Sunday.

This is a big day, it’s time to draw a lottery, and it’s the first time for Gao Zhendong to draw a lottery after working. When he got up in the morning, he was ready to burn incense and take a bath, to see what good things he could draw.

Gao Zhendong went out to take a bath in the bathhouse first, asked the bath master to rub the mud off him thoroughly, then returned home refreshed and boiled water to wash his hands. Although he didn't know what use washing hands would have for drawing the lottery in his mind, he just went for it.

"System! Lottery!"

There were neither sound nor light effects. The only change was that there was an extra set of thin paper materials in his storage repository.

Gao Zhendong pulled the curtains, took out the documents, and looked through them carefully under the light.

"Holy crap!!! I won the prize!!!"

"I told you, which kid cries every day?! I won't read all the bad online novels all my life. This thing is not the best, but at least it is a small best. The key is that it is especially suitable for my current situation."

After all, the return air furnace has little to do with his actual work. It can be used as a side dish for scientific research and may even be passed down as a good story, but as a main research direction and core work result, it is somewhat weak.
