Now that Zhang Yuan is not willing to find a mechanism to test the components of the residual liquid. Maybe, some secrets have been exposed inadvertently.

If things get bigger, it will be more than worth the effort.

He still understands the principle that wealth is not exposed. Just enjoy the benefits my father gives himself.

"Oh, forget it, you will know what you should know. If you shouldn't know, don't go and explore it randomly... Since my father is vague and has not explained the reason, he must have his own reasons."

Zhang Yuan suppressed his curiosity and threw this matter out of his mind.

There are many shops on the pedestrian street, including convenience stores, clothing stores, restaurants, fruit stores, etc.

The fruits here are very cheap and fresh. There is a seaweed plant called "Porcelain Grass", a new species cultivated a hundred years ago. It is called "a gift of space given to mankind by God."

This thing tastes sweet, very much like grapes. The flesh is rich in antioxidant B-group vitamins, which are very good for human health.

Long-term consumption can even directly increase the average life span of human beings.

Zhang Yuan bought a few kilograms of "Porcelain Grass", which cost 3 yuan per kilogram, and was about to go home and eat it slowly.

Next is the clothing store, which is all in one glance.

Even though logistics is very developed now and online shopping is cheap, women still cannot get rid of the bad habits of shopping. For them, online shopping and shopping are actually different things.

This is because there is no oil in this era, and clothes are a little expensive.

It takes a lot of financial expense to own a variety of clothes. In this way, women like shopping even more. For them, it is better to see and touch.

Zhang Yuan walked into a store selling underwear and bought a few pieces of underwear, underwear and socks.

"After 20% off, a total of 887 yuan!"

"It's cheaper, boss." Zhang Yuan tried to bargain.

"Sorry, don't bargain!"

The reason why there are waiters in the store is to increase employment. Even though the productivity and social welfare system of Xia State can support many idle people, if the overall unemployment rate is high, these people will do nothing and the crime rate will be high.

Therefore, it is better to add some low-end professions without technical content.

It's so expensive! Four pairs of underwear, three pieces of underwear, and five pairs of socks are not a brand, but it actually costs more than 800 yuan. The salary of an ordinary person is only 40,000 or 50,000 a month.

Zhang Yuan shrugged his nose, feeling that his bargaining level was too bad, or maybe the other party was a man.

If you are a waitress, you may be impressed by your appearance and get discounted.

However, no matter how expensive it is, these are all made of nano materials. They are of good quality and are not easy to get dirty. They will not be damaged after wearing for a few years. This is still cost-effective.

He planned to take these clothes to the spaceship for use.

When I walked out of the store, I caught a glimpse of the latest clothing advertisement of a well-known clothing manufacturer, "Nanoplastic fabric clothes, ice-like texture, unique silky enjoyment..."

I touched this white dress like stockings casually, and it was really cold.

Usually clothes are isolated from infrared radiation, but this nanocloth has no ability to keep warm at all. The nanopores in the material can help the human body dissipate heat through infrared radiation.

Of course, because the new material is thin and soft, girls will show off their figure when wearing it. The price is also quite expensive, and one piece costs more than 2,000 yuan.

Nanotechnology changes the world, including wearing.

Zhang Yuan touched it a few times and felt very good. He was thinking in his head: "It looks a bit like white stockings, quite soft."

"Oil is really a good thing. Why are clothes from the old era so cheap?"

"They actually burned oil as fuel!"

Zhang Yuan sighed.

He also recalled the people of some countries on earth who had just eaten their fill, but still couldn't wear clothes and were in dire straits.

He didn't feel much sympathy in his heart, because most of these countries were the original oil-producing countries.

They used to be the richest country on the earth, but the current situation is only one word to describe: sitting in vain.

Flowers are not red for a hundred days, and people are not blessed for a thousand days. There are too many countries that have declined in history. Whether it is an individual or a civilization, it always has its own lifespan.

Rising in crisis and declining in comfort and enjoyment is an eternal truth. When you are rich, you don’t find a way out for yourself, and now you can only suffer.

Next, Zhang Yuan went to a life insurance company and wanted to buy two additional pension insurances for his sister-in-law and husband.

Even though their family is not short of money at present, society is changing and people have good fortune and good fortune at any time. What happens in the future?

One more insurance is always good.

"...Please don't tell the parties involved first. Is it OK after two years? The fee is paid in one lump sum, and there is no need to pay in installments."

"sure!"

The beautiful waiter was extremely enthusiastic and had a flushed face.

There is a commission for selling insurance, especially for such a big deal. She is so happy. In addition, the other party is a handsome guy, and her tone is very well-educated, giving people a very comfortable feeling.

"The total cost of the two people...300,000 yuan. After retirement, each person will be reimbursed 2,000 federal dollars per month. If inflation is not calculated, the capital will be repaid in 75 months."

"Okay!" Zhang Yuan signed readily and paid the fee.

I don’t feel sorry for being a prodigal family. Even if it’s a small gift to these relatives before leaving.

After doing this, there are not many trivial matters to be troubled.

Zhang Yuan returned home and sorted out the matters at hand.

For various memorandums and for some irrelevant things, I might as well give up treatment, and now I just want to learn.

Learning with a lot of liver!

In the next few days, Zhang Yuan was happily writing various books, first trying to review all university courses, including "Mathematical Analysis", "Mathematical Analysis", "Real Variable Functions", "Modern Algebra", "University Physics", etc.

Days pass quickly day by day.

His biggest wish at the moment is to understand the articles his father left on his tablet.

These articles are a bit similar to casual notes. They should have recorded the inspiration they generated at random when my father was working, and it looked a bit messy.
Chapter completed!
