Zhang Yu could only accept the two small goldfish that Xie Zhiyuan got from somewhere, then turned around and got some more items for the Xie family based on the price difference.
Later, he did two more business with the old woman who stopped him to buy grain from him.
He used the grain in his hands to exchange for some diamonds and jade from the old woman, and through her, he exchanged a lot of jade, jade, antiques from people with a similar family background to hers...
Anyway, during this period of time, he was able to let himself go, and it was a joy to be wild.
Some of the food grown in the secret space and the chickens and ducks raised in the secret space were also consumed.
Of course, he also gained a lot during this period. Not to mention the calligraphy and paintings, he received several small goldfish alone.
But compared to the little goldfish, those people prefer to trade with him using jade, jade, calligraphy and paintings, etc. Compared with these things, they feel that gold is their last resort.
Gold is easy to sell on the black market, and no matter how hard it is, you can risk going to a bank to exchange it, but for jade, jade, antiques, etc., few people will exchange it for food.
Zhang Yu was very satisfied when he saw the things in his hands. Every time he got something, he couldn't help but think about how much it would be worth in future generations. He always felt that he had taken advantage, so he always gave more or less something.
.
In this day and age, there is no one who doesn't have thirty or fifty good things. Zhang Yu picked and picked and got a lot of things.
Those who exchanged things for food were also very satisfied. They also knew that the things in their hands were valuable and they knew they were losing money, but in this era, food is more important than anything else. Only with food can they survive.
Otherwise, if your life is gone, what are you going to do with these jewels? Now that these things can be exchanged for food, it is the best thing.
They all feel that with their own abilities, they can still make money if their things are gone, but if their lives are gone, they have nothing.
Even though they offer very low prices for the things in their hands, some people who have food on the black market are still unwilling to exchange them with them. If they can exchange their goods for food on the black market, they won't get much at all.
So when they saw what Zhang Yu brought out, they were very satisfied and felt that the exchange was worth it.
In this way, the transaction was carried out to the satisfaction of both parties.
Those people received food and life-saving things, and Zhang Yu also received things that he thought would increase in value, and felt that his wallet was bulging again. This transaction was considered a happy one for everyone.
Before the New Year, Zhang Yu did not forget his sister-in-law and uncle in Beijing. He also found a reason to mail a package to his sister-in-law and the others, which contained some bacon. Each of his sister-in-law and uncle had a cotton-padded jacket and cotton trousers.
The package was stuffed so full that there was no gap left. In short, he would not miss any opportunity to dump supplies into his home.
And those cotton-padded jackets and cotton trousers were all obtained when he signed in during the Chinese New Year.
When it comes to signing in for the New Year, he still can’t forget the shock he felt at that time.
On New Year's Eve, Zhang Yu started signing in.
"The system starts signing in today."
"Ding, congratulations to the host for successfully signing in today! Because today is New Year's Eve, you got ten times the critical hit."
Zhang Yu was simply shocked when he heard about ten times the critical hit. You must know that when you sign in for something as important as missiles and secret space debris, it was only twice the critical hit, triple the critical hit, and now it is ten times the critical hit.
With curiosity and trepidation, Zhang Yu began to check the results of this sign-in.
In addition to the same New Year's gift package as last year, there are also more than 20 sets of cotton-padded clothes and trousers, and some information on weapons.
The last thing made his eyes widen. He was stunned for a long time and pinched his thigh with his hand before he realized what he was doing.
The last thing was a simulation classroom. Zhang Yu looked up the instructions carefully before he figured it out.
This simulation classroom basically covers all courses from ancient times to the future, but it is still inactive.
According to the sign-in instructions, after the simulated classroom is activated, an environment similar to the classroom will be formed. This environment only allows Zhang Yu's mental body to enter. After entering the classroom, Zhang Yu outside will become sluggish.
When you enter the simulation classroom for the first time, you can choose three courses. The classroom will choose a suitable teacher for Zhang Yu and teach him one-on-one.
If you want to choose content other than the three courses, you need points. The points vary depending on the depth of the course in Chengdu.
In this simulation classroom, points are the most important thing. Basically all activities consume points.
The way to obtain points is also very simple. After studying the course, there will be an exam. After the exam, different points will be given according to the results. If you fail, the points will be deducted.
After understanding the rules, Zhang Yu was extremely pleasantly surprised. This was simply another golden finger for him besides the system.
After having this simulation classroom, he can learn more knowledge and no longer have to worry about how to use the technology to sign in the system, but Kongshou Treasure cannot be used.
With this simulated teaching space, he can make up for the shortcomings and slowly show that he is a genius in certain aspects. Then, after everyone accepts that he is superior in certain aspects, he can slowly come up with various
Results.
Thinking of this, Zhang Yu once again searched for other rules about simulated teachers, and finally found a line of small words at the bottom of the system introduction.
It is written above that after the mental body enters the simulated teacher, do not choose courses easily. Make sure you are in a safe environment where no one will disturb you before choosing courses.
Each course in the simulation classroom will be divided into a different number of chapters according to the difficulty level, and each chapter has enough content.
Once you choose to study, you will not be able to leave the classroom until you have finished studying the content of this chapter. You can only leave the classroom after studying the content of this chapter and passing the exam.
The system introduction only contains these things, and there is no introduction about the time ratio between the simulated classroom and the outside world, so Zhang Yu is not sure when he will pass the first chapter of the exam.
If the time ratio between the simulated classroom and the outside world is too small, and he takes too long to study a chapter, it will cause him to continue to be in a daze in the outside world, and others may find something wrong.
So in Xie's house, he really didn't dare to activate the simulation classroom rashly and enter the learning state.
Another reason was that it was not convenient to do some things at Xie's house, so he thought about finding a reason to stay in his own secret space before entering the simulation classroom after returning to Beijing.
Thinking of this, Zhang Yu couldn't wait to return to Beijing.
