After relying on the motherland, my supermarket has become more and more prosperous.

Long before, Jiang Wanwan already knew that the system could be upgraded.

However, after that, the system started the new world step by step, and there was no other movement.

Jiang Wanwan didn’t think too much about it, thinking that it would take a long time before the system upgrade was available?

But I didn't expect that this incident would come so suddenly and without any warning.

The trial, which determines whether the system can be successfully upgraded, is the top priority of this matter.

At this moment, Jiang Wanwan was in the room, listening attentively to 007's explanation.

"This system is a trading system for all worlds. The upgrade trial is naturally centered around trading. The host needs to travel to the trial world and complete as many transactions as possible to obtain resources."

Complete the transaction and obtain resources?

Isn’t this similar to what Jiang Wanwan did in the previous six worlds!

Or in other words, the first six worlds are actually trial experiences given to the host before starting the upgrade trial?

If this is the case, then the routines in the trial world should be similar to those in the previous six worlds, right?

Thinking of this, Jiang Wanwan's originally anxious heart relaxed a little.

While thinking, he asked tentatively: "Can you tell me the type of trial world? Or the criteria used by the system to select worlds?"

This somewhat overstepping question made 007 pause for a moment before he answered again.

"The background of this trial world will be selected from the history of the host planet itself. Eras with major turning points are more likely to be chosen!"

Hmm...hmm? Jiang Wanwan couldn't help but widen her eyes.

She was just asking tentatively, but she didn't think 007 would really answer.

Moreover, 007 not only answered, but also revealed extremely crucial information.

This is totally unlike the stingy 007 of the past.

It seems that 007 also hopes that the system can be upgraded successfully. This is a good opportunity!

Jiang Wanwan didn't think about it anymore and carefully analyzed the information 007 told her.

The history of the host planet itself? Do you mean the actual historical background?

As for major turning points, the founding and demise periods of each dynasty should all be included, right?

However, Jiang Wanwan was more curious about another question.

"From the historical context, we choose an era as the trial world. Is it the real world? Or is it a technological virtual world?"

Since it is called history, it is naturally an era that has passed. So is this trial world real or fake?

If this is true, could it be that a Level Nine technological civilization has already mastered the method of returning to the past?

If it is virtual, then are the resources obtained from it also fake?

These two completely different results will affect Jiang Wanwan and lead to a series of issues that she will need to consider later.

"Of course it's the real world!" 007 answered without hesitation.

Then, he explained in simple and easy-to-understand words: "But it doesn't mean you can go back to the past, but travel to another dimension, which is similar to the existence of a parallel world."

What is another dimension? Jiang Wanwan is not a scientist and cannot fully understand the meaning.

But when they talked about parallel worlds later, she immediately understood and had a rough idea in her mind.

Anyway, it’s just another time and space, a real world formed according to the course of history!

In other words, if Jiang Wanwan is lucky, she might even meet a famous person in history in the trial world?

My charming ancestor, Ying Zheng? Li Shimin, the great Tang emperor who drew tributes from all nations? Wu Zetian, the first female emperor in history? Zhu Yuanzhang, who started with a bowl? And the great man who founded New China? ...

Figures flashed through Jiang Wanwan's mind one after another, and she felt that no matter which one she met, it would be worth it!

It took her a long while to finally suppress the wild fantasies in her heart.

Jiang Wanwan had thought about it. Why not just ask 007 which era he would travel to?

But in the end, it was not done.

Judging from the way 007 is letting the water out today, if it could say it, it would have said it just now.

Since it wasn't said, it certainly couldn't be said, or it didn't know either.

So why bother asking further? There are still many problems to come, and we all rely on 007!

For example, Jiang Wanwan opened her mouth and asked the doubts that had just arisen in her mind.

"In the real historical world, there shouldn't be any resources worth trading, right? Are we supposed to be trading antiques or something like that?"

It’s not that antiques are bad!

Antiques are certainly valuable. They can be used to study history and culture, and they can be collected...

The key point is that the resources Jiang Wanwan obtained in the six worlds she had previously traveled through were all special and unique.

Such as crystal cores, thousand-year-old herbs, martial arts, water-repellent beads, high technology, merit, faith, luck, lifespan, etc.

These resources do not exist on Earth and obviously did not exist in the historical world.

Although antiques are valuable, they are not on the same level as these resources.

The previous worlds were full of special resources, but in the Trial World, there are only antiques? That doesn't make sense, does it?

It's clearly a trial to upgrade the system level, so why are the materials obtained downgraded?

"Host, please be aware that in the trial world of upgrading the system, the resources obtained are not physical objects and cannot be brought back to Earth. They will all belong to the system!"

What? Jiang Wanwan's eyes widened again, not daring to believe what she heard.

Originally, resources were obtained from other worlds, with half of the system and half of the rules being their own.

Once you enter the trial world, all resources will directly belong to the system?

So, she provided manpower and goods, worked hard to open a store, spent time and energy, but in the end, she got nothing?

Well, Jiang Wanwan might still gain something.

If the system can be upgraded successfully, she will at least get a system with many new features.

If the system can be successfully upgraded, then the free manpower and material resources invested during this period will be worth it!

Furthermore, the trial world is a historical background, and the guests there can all be considered ancestors.

The goods that were brought over eventually fell into the hands of our ancestors, so it wasn't a loss at all.

Thinking of this, Jiang Wanwan suddenly felt much better.

Without further deliberation on whether it was worth it or not, she thought for a moment and asked again.

"So, what are those resources in the Trial World that cannot be brought back to Earth?"

It's not a physical object? Could it be a knowledge resource?

For example, the bronze ware production process, medical books lost in the long river of history, personal works, recipes, incense books, etc.?

"It's the national destiny factor!" 007 said a completely unfamiliar name.

Jiang Wanwan was naturally puzzled and asked, "National Destiny Factor? What is that?"
