After Zheng Sheng finished reading it, he didn't understand the meaning of these words for a while. What changes the trend, what achievements, what official openings, what conditions can be exchanged, what are these things?

So many strange things suddenly appeared. Zheng Sheng thought to himself: "What the hell is going on? Can you explain this to me? ”

"Absolutely." A familiar voice came from behind.

Zheng Sheng's spirit was shocked, he turned around and looked at her in shock: "Sniff!" How did you end up here? ”

Zheng Sheng felt a tingling of his scalp, how could she appear here? Could it be that she also crossed over?

"I'm a ...... to help the host use this system. The assistant is not Liu Wei'er known to the host, but because the person who is most impressed by the host is her. That's why I became her. ”

Zheng Sheng felt a lot more relaxed, looking at her appearance, he felt awkward again, so he waved his hand and said, "Can you change your appearance?" You're what she looks like, and I can't quite accept it. You'd better be someone I don't know. ”

"Liu Yan'er" had a strange expression of surprise on her face, and then she instantly turned into a young man who was completely unfamiliar to him.

Zheng Sheng nodded with satisfaction, no matter what magical things were discovered in this place, he could no longer be surprised.

Zheng Sheng touched his chin and said to himself: "Let me sort it out first, are you a system assistant?" ”

"Yes."

"This time, it was because I defeated the Yellow Silk Thief that the system was officially opened?"

"Not exactly. After the host defeated the Yellow Silk Thief, Shi Chong gave up the idea of continuing to plunder the merchants and dealt with his subordinates. All of them can be regarded as slightly changing the trend of the world. ”

"Changed the trend of the world, is it a condition for the system to be officially opened?" Zheng Sheng asked.

"Yes."

"That's not right, I've exchanged so many things before, and I've had a lot of impact on this world, aren't those considered changes in direction?"

"Not really. Those items changed the world to a certain extent, though. For example, the diamonds exchanged by the host are extremely rare in this country. But how many diamonds can the host redeem? After the death of the host, all that is left in the country is these things. It has no impact on the general trend at all. Like a ripple of wind blowing across a lake, it can only exist for a short time. ”

"Without the yellow silk thief, will it really have an impact on the general trend of this world? What are the implications? Zheng Sheng asked.

"The host defeated the Yellow Silk Thief as if he had thrown a small stone into a lake. As for what the impact is? He smiled and stopped talking.

"Why did I change the trend and you showed up?" Zheng Sheng asked.

He was equally smiling and silent.

"Can't tell me about this either? Well, then you tell me, what can I do now? Zheng Shengdao.

"Come and see." He walked up to the screen and pointed at the screen with his hand, "In the future, the host doesn't have to meditate on the exchanged items in his mind, and can operate on this screen." ”

Zheng Sheng looked at his operation and found that after returning to the main interface, in addition to the icon of the badge, there was a small icon in the shape of a scale.

"Click on it and you're good to go."

Zheng Sheng nodded, "So, is it still the exchange three times a month?" Hey? No, no! ”

Zheng Sheng suddenly thought of something, "Shouldn't it be the night of the thirteenth today?" Thirteenth, how did I get here? ”

"Because...... The system is officially on. In the future, the host can come here every day. Of course, there are still only three basic exchanges a month. However, the host can choose the time of redemption at will, not just on the three days of the month. ”

"Why is it being upgraded today? How many days ago did I defeat the Yellow Silk Thief? Zheng Sheng suddenly thought again.

"The host should find out the reason for this tomorrow."

Zheng Sheng thoughtfully: "The system is officially opened, can I exchange for more advanced things?" ”

He shook his head and said, "What the host can exchange before, it can still be exchanged." What you can't exchange before, you still can't exchange anything. ”

"So what's the use of this system being officially opened?" Zheng Sheng said angrily, "Just one more screen and anthropomorphic assistant?" ”

"It's more than that. And this. He smiled.

I saw a balance icon that was exactly the same as the previous one appeared on the screen, but below it were the words "conditional exchange".

"Conditional redemption?" Zheng Sheng was a little puzzled.

He clicked on the icon: "The so-called conditional exchange means that after the host meets a certain condition, the host will be given a chance to exchange any item. ”

"Any items?"

"Yes, any item."

"On what terms?"

"Host, please look."

Zheng Sheng looked at the screen.

1: Earn a first-class title in any of the following countries: Jin Empire, Roman Empire, Sassanid Kingdom.

Zheng Sheng was a little confused, first-class title? Rome and the strange country behind, not to mention whether he can be lucky enough to set foot there in this life, just talk about the first-class title of the Jin Kingdom, it should be the king of the county!

Moreover, it is impossible for a person with a foreign surname to obtain the title of county king, and the highest title that a person with a foreign surname can obtain is only the county duke.

But whether it is the king of the county or the prince of the county, it is inevitable that he is too far away.

2. Serve as the chief executive of the first-level administrative region of any of the following countries: Jin Empire, Roman Empire, Sassanid Kingdom.

3. Commander of 30,000 soldiers in any of the following countries: the Jin Empire, the Roman Empire, and the Sassanid Kingdom.

Zheng Sheng finished reading it with a dull gaze, didn't dare to think about any thoughts, and continued to look down.

Four: Create 100 texts that will last for thousands of years (2/100 of the current progress).

Zheng Sheng's spirit was shocked, "Progress two? Is it a thousand-character essay and the Peach Blossom Spring? Copyed, too? ”

"Count."

"This condition seems to be ...... It's not feasible. Zheng Sheng's words became deeper and deeper the more he spoke, a hundred words that have been circulated for thousands of years? It's a rhythm that drives him crazy!

Where does he remember hundreds of famous articles?

Zheng Sheng continued to look down, he read it hastily, and the conditions behind it were all the way to the twelfth, but they were not something he could easily complete!

And the last one, it seems that there is still a possibility to do it: to slightly change the general trend of the world (whether it is achieved or not is determined by the system).

"It's hard to redeem this condition." Zheng Sheng frowned.

He whispered, "As long as the host works hard, it will definitely be achieved." ”

"But that's not something I can do anytime soon!" Zheng Sheng said angrily.

"Don't worry, host. Because the host has completed the official opening of the system. I can give the host a free conditional redemption. ”

Zheng Sheng's face softened slightly, "This is a big gift package?" So, I'm ready to redeem it now? ”

"Yes."

"I want a medicine that can cure Liu Wei'er's condition." Zheng Shengdao.

"Okay. However, there are too many such drugs. So, I recommend to the host a 'panacea' from your past life memories! ”

"Panacea?" Zheng Sheng was stunned.

"Penicillin."

"Penicillin!" Zheng Sheng suddenly realized that this was a name that he had almost forgotten. But undoubtedly, this is a very good choice. In his previous life, he remembered reading about penicillin in books and in movies. In those stories, it's almost like a miracle cure.

"Okay, I'm going to redeem it."

"As you wish." He smiled.
