It's time to learn

Even now, Zhang Yuan is unwilling to randomly find an institution to test the composition of the residual liquid. Perhaps some secret was accidentally exposed.

When things get big, the gains will outweigh the losses.

He still understands the principle of not revealing wealth. He can enjoy the benefits that his father gives himself.

"Oh, forget it, what you should know will always be known. Don't explore what you shouldn't know. Since Dad is vague and hasn't explained the reason, there must be his own reason."

Zhang Yuan suppressed his curiosity and left the matter directly behind.

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

The fruits here are very cheap and fresh. There is a seaweed plant called "Portuguese grass", which is a new species cultivated a hundred years ago and is known as the "space gift from God to humanity".

This thing tastes sweet, much like grapes, and its flesh is rich in antioxidant B vitamins, which are very beneficial for human health.

Long term consumption can even directly increase the average lifespan of humans.

Zhang Yuan bought a few pounds of "Portuguese grass" for 3 yuan per kilogram, ready to go home and eat slowly.

Next up is the clothing store, which is everywhere at a glance. Even though logistics are well-developed and online shopping is cheap, women still cannot change the bad habits of shopping. For them, online shopping and shopping are actually two different things.

This is because in this era, there was no oil and clothing was a bit expensive.

To have a diverse wardrobe of clothes, there is a significant economic cost to pay. As a result, women enjoy shopping even more. For them, it's also good to take a look and feel.

Zhang Yuan walked into a lingerie shop and casually bought several pieces of underwear, underwear, and socks.

"After a 20% discount, the total is 887 yuan."

"Cheaper, boss, "Zhang Yuan tried to negotiate Sorry, no bargaining!

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

So, it's better to add some low-end professions with no technical content.

How expensive! Four pairs of underwear, three pieces of underwear, and five pairs of socks, which are not brand goods, cost over 800 yuan. An ordinary person's salary is only four or five thousand yuan per month.

Zhang Yuan shrugged his nose, feeling that his bargaining level was really poor, or perhaps because the other party was a man.

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

However, it's expensive. These are clothes made of nanomaterials, which are of good quality and not easily dirty. They won't be damaged even after wearing for a few years. In this way, it's still cost-effective.

He plans to take these clothes to the spaceship for use. As I walked out of the store, I caught a glimpse of the latest clothing advertisement from a well-known clothing manufacturer, which read, "Nanoplastic fabric clothes have an icy texture and a unique silky enjoyment."

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

Normally, clothes are insulated from infrared radiation, but this nano garment has no thermal insulation ability 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 look very slim when wearing it. It's also quite expensive, costing over 2000 yuan per piece.

Nanotechnology changes the world, including clothing.

Zhang Yuan touched it a few times and it felt incredibly good. He thought to himself, "It looks a bit like white stockings, it's quite soft."

"Oil is really a good thing, how could clothes from the old days be so cheap?"

"They actually burned oil as fuel! "Zhang Yuan sighed.

He also associated with the people of certain countries on Earth, who have just had enough to eat, but still cannot put on clothes, and are in deep water and heat.

He didn't have much sympathy in his heart, as most of these countries were original oil producing countries.

They used to be the wealthiest country on Earth, but now there is only one word to describe their current situation: sitting back and eating nothing.

There are too many declining countries in history, whether it is individuals or civilizations, there is always a lifespan of their own.

The principle of rising in crisis and declining in comfort and pleasure has never changed. When I was rich, I didn't find a way out for myself, and now I can only suffer.

Next, Zhang Yuan walked into a life insurance company and wanted to purchase two additional pension insurance for his sister-in-law and her husband.

Even though their family is currently not short of money, society is changing, and people have unexpected misfortunes. What should happen in the future?

An extra insurance policy is always good.

"EE... Could you please not tell the parties yet? Two years from now, is that okay? The fee is paid in full in one lump sum, without installment payment."

"Of course you can!"

The beautiful waiter was exceptionally enthusiastic, with a flushed face.

Selling insurance has a commission, especially for such a big deal, she couldn't be too happy in her heart. In addition, the other party is a handsome guy with a very cultured tone, giving people a very comfortable feeling.

"The total cost for the two is... 300000 yuan. After retirement, each person will receive a monthly refund of 2000 federal dollars, and if inflation is not calculated, 75 months will be paid back."

"Okay! "Zhang Yuan signed briskly and paid the fee in full.

Losing the family doesn't hurt, even if it's a small gift given to these loved ones before I leave.

After finishing this, there aren't too many trivial matters to bother with. Zhang Yuan returned home and organized his current affairs. For various memorandums and for some unimportant matters, simply give up treatment and just want to learn now.

Explosive liver learning!

In the next few days, Zhang Yuan happily painted all kinds of books. First, he tried to review all college courses, including mathematical analysis, mathematical analysis, Real Variable Function, Modern Algebra, College Physics, etc.

The days passed quickly day by day.

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

These articles are somewhat similar to casual notes. It should be that my father casually recorded the inspiration he generated while working, which looks a bit disorganized.

But Zhang Yuan has no doubt about its value.
