This upgrade cost fifteen thousand taels of silver, but Xue Yao didn't feel distressed at all.

When she used to upgrade the system, she also asked for silver.

Now, after the upgrade, she can get more benefits, and she naturally doesn't care about the silver.

What's more, fifteen thousand taels of silver can make the purification system help them scan for poisonous things in advance, which greatly ensures their safety, and Xue Yao is very happy.

However, they need to wait ten days for this upgrade before the system can come out, and not only that, they can't even use the mall now.

The system has reminded them before that the system needs to be fully upgraded, so the mall will also be temporarily closed.

Xue Yao and Jiang Zhan's business in the capital has always been very good, even if the mall can't be used, the impact on them is not very great.

After the system was successfully upgraded, Xue Yao found that he had ignored some things when he was checking the mall before.

After careful observation, she realized that there were more things in the mall that looked extremely elegant, as if they were antiques.

However, Xue Yao has never studied antiques and calligraphy and painting.

Besides, this is ancient times, and even if there are antiques, some people don't necessarily spend money to buy them.

Instead, they prefer calligraphy and painting with a sense of meaning.

For them, antiques are just antiquities.

After Xue Yao saw what was inside, he immediately told Jiang Zhan about it.

She felt that these calligraphy, paintings and antiques could be put to good use.

"Ah Zhan, you help me look at these calligraphy and paintings inside, I don't know much about these!" They don't have any secrets from each other anymore.

Jiang Zhan is very clear about Xue Yao's origin, so she has no appreciation for ancient calligraphy and painting.

"These calligraphy and paintings are left by some extremely famous people!" Jiang Zhan recognized the signature on the calligraphy and painting immediately.

"Can we take it out and sell it?" In ancient times, many things were extremely avoided, especially for some things from the previous dynasties, others did not dare to ask for them.

Except for Xue Yao's relatively clear understanding of some things about the Daxuan Dynasty, she didn't know anything about the previous dynasty.

The people and Jiang Zhan did not easily mention the matter of the previous dynasty, after all, the Daxuan Dynasty had been established for hundreds of years.

Most of the people don't know about the things of the previous dynasty, and now there are just some rumors among the people.

It was not clear to everyone whether these were true or not.

As for the calligraphy and paintings left by the previous dynasty, no one dared to ask for them at the beginning.

Now, after so many hundreds of years, I am afraid that there is nothing left.

However, carefully sailing the 10,000-year-old ship, Xue Yao felt that it was better to pay attention.

"Yes, these are all items from this dynasty!" Jiang Zhan checked it carefully and found that the time of the calligraphy and painting was from this dynasty.

"It has been more than 500 years since the establishment of the Daxuan Dynasty, and these things can be called antiques!" Xue Yao completely let go of it now.

In any case, she would not miss this great opportunity, after all, they have spent so much energy and effort to upgrade the system.

"Ah Zhan, I want to take out these calligraphy paintings and porcelain for auction!" Xue Yao felt that they would definitely bring a lot of benefits to herself and Jiang Zhan.

Although they are not short of silver flowers, the more silver the better......

"What are the other differences after this upgrade?" After Jiang Zhan saw those things, a glimmer of light quickly flashed across his eyes.

In the past, something was added to the system with each upgrade, but it didn't change as much as this one.

He also dealt with the system a few times, it seemed to be a bunch of data, but it was actually precise, Jiang Zhan didn't believe that the system would have so many things at once, and they didn't have to pay any price.

"Yes, there are more things in it this time, and the purification system has also been upgraded, and most importantly, some other interesting functions have been added...... Xue Yao quickly said all the changes in the system.

Through Xue Yao's description, Jiang Zhan found that their upgrade this time was a significant improvement compared to before.

"Yao'er, I want to have a good chat with the system!" Jiang Zhan frowned.

"Did you notice something wrong?" She knew Jiang Zhan too well, and every time he showed this look, it meant that he was worried about something.

"This upgrade is different from the past, I want to ask about the system!" He said straight about his purpose.

"Good!" Xue Yao immediately called the system out.

"Let me ask you, what are the pros and cons after this system upgrade?" Jiang Zhan went straight to the point and asked the system to tell all the hidden dangers.

There is no free banquet in the world, and Jiang Zhan always feels that something is wrong.

However, Xue Yao didn't know at all, so he could only question the system.

After all, only it will know.

"What are you suspicious of, this system never lies!" The system milk is fierce, and the milk is fierce.

It was extremely unhappy with Jiang Zhan's questioning.

"You're really not lying, but you didn't tell us the pros and cons of upgrading the system in advance, am I right or not?" A sneer appeared on Jiang Zhan's lips.

He is not a system that Xue Yao trusts as much.

After all, when she came to her, she relied on the instructions of the system, and the system did help her when she needed it the hardest.

In this case, Xue Yao believed that it was inevitable, and it would only tell Xue Yao about the benefits of upgrading every time, but the disadvantages were not mentioned at all.

Today, if he hadn't seen those precious calligraphy and paintings, Jiang Zhan would not have been suspicious.

The exchange price of such a valuable thing is not very high.

Jiang Zhan was suspicious all of a sudden, so he decided to find the system to make it clear.

Since the continuous upgrades, the system has become smarter and more cunning......

"Don't worry, this system won't harm you!" The system doesn't want to say more.

"In that case, why do you keep avoiding the important?" It still wants to deceive itself with that little trick?

Jiang Zhan was too lazy to communicate with the system before, after all, he had to go through Xue Yao every time, and he felt a little troublesome......

"Me!" The system didn't expect Jiang Zhan to be so persistent.

"You don't really have something to hide from me, do you?" Xue Yao's eyes narrowed slightly.

At first, she thought that the system would tell Jiang Zhan everything directly.

As a result, it kept talking about him left and right, and Xue Yao suddenly became suspicious.

"You are my host, if something happens to you, I will not be able to survive, I will never harm you!" The system was dissatisfied.

"I didn't say that you would hurt Yao'er, I just asked you to tell the evils, you are so secretive, it can't be that there is really some ulterior secret, right?" Jiang Zhan's eyes were cold.

"Nonsense, what secrets can I have, I'm a system!" Although its tone was still as flat as ever, Jiang Zhan could hear that his heart was empty.

"If you don't say it, I'll just block you, and I won't let you out in the future!" Xue Yao was furious.

She's always hated it when someone hid it from her, especially from the beginning when she said she was going to help her.

For so long, she has always treated the system as a friend.

Maybe she had the intention of using it at first, but after a long time, she gradually developed a trace of affection for each other......

"You guys are so annoying, you guys are teaming up to bully this system!" The system is starting to be coquettish.

"Hehe......" Jiang Zhan rewarded him with a sneer.

"When did you become a dramatist?" The corners of Xue Yao's eyes twitched.

The system simply ignored them.

"Don't think that silence can fool things over, you know my temperament, once you anger me, I will do anything!" Xue Yao continued to rub her palms.

The attitude of the system is really too easy to be suspected.

Compared with the system, she is naturally the person who believes in her pillow more.

Jiang Zhan was devoted to her, and he was reluctant to hurt her at all.

However, the system is not very personal data, and it only values upgrades......

The system had no choice but to tell the truth.

"You have gone too far, hurting my innocent and young heart!" The system complained in a cute little milk voice.

"Hey, don't do this, I'm getting goosebumps, and where did you learn these words?" Xue Yao said.

"This system has been with you since the 21st century!" The system said angrily, "Actually, after the upgrade, it really doesn't have any impact on you, but the mandatory tasks that need to be completed in the future will increase!" ”

"What else?" Xue Yao felt that the system's words were not finished.

"Each upgrade costs more, and the difficulty of the missions keeps increasing!" It didn't mean not to say it, it's just that it knew Xue Yao's temper too well.

If she knew these things, she wouldn't necessarily choose to level up.

It's hard to get enough points, and if you don't upgrade her intelligence, you can't get to grow, and of course the system won't be happy.

Therefore, it will talk about the benefits of upgrading and let Xue Yao upgrade as soon as possible.

Now that the raw rice is cooked, it is too late for them to regret it.

However, the system didn't expect that the first person to find the clue would be Jiang Zhan.

"You shouldn't have anything to say yet!" Jiang Zhan said indifferently.

"Okay, you're getting better and better now, and you actually play word games with me?" Xue Yao gritted his teeth and said, "Believe it or not, I won't need the system in the future!" ”

"You won't!" Once the system is tied, no one can untie it.

"Don't worry, I don't plan to die with you, anyway, your existence will not affect me, I just don't touch the things in the mall again!" Xue Yao's words made the system almost explode.

If you don't have points, it will fall asleep after a long time.

Although it will not die out completely, it will also do great harm to it.

The most annoying thing is that Xue Yao will not harm herself if she does this.

"You're amazing!" The system told Xue Yao and Jiang Zhan about the drawbacks it tried to hide in the end.

It turned out that after it was upgraded, Xue Yao might get a box when he completed some tasks.

This is an additional gift from the system.,But the system isn't sure.,After opening it, the contents are good or bad.。

After all, this is the person who made it, and it was set up in the first place, and even if it was a system, it couldn't change the object inside.

After Xue Yao heard this, she silently breathed a sigh of relief, although the upgrade did have drawbacks, it was just not as powerful as she imagined, so she planned to let go of the system generously and no longer pursue it......
