Sign in and get rich in farming

Yu Hongdou swore that the experimental instruments she used when she was in school were not as complete as those on the two long tables in front of her. After all, her major had nothing to do with chemistry.

When this scene appeared in this background, Yu Hongdou really felt as if she was in another world.

"Alchemy?" The scene was enough to shock Yu Hongdou, but Tan Yanlin delivered another critical hit.

"Your brain would be worth digging out and studying in the eyes of some weirdos." Yu Hongdou was really impressed by the genius brain with such terrifyingly strong logic.

She was absolutely sure that Tan Yanlin was a pure ancient person, but Yu Hongdou felt that he always hit the nail on the head about these things that she couldn't even tell whether they were fantasy or science fiction.

"...Do you know that what you said is a bit scary?" Tan Yanlin glanced at her speechlessly, walked to the table and lit the candle.

Yu Hongdou looked innocent and she was telling the truth.

"It seems that two groups of people have been stationed here." Tan Yanlin raised the candle and looked around the space again.

The space is not big, about six zhang long, thirty zhang and thirty centimeters wide, and less than two zhang high.

The walls were plastered with mud and covered with a layer of felt, on which a lot of sheepskin and silk were nailed with wooden spikes.

The silk had weathered and become brittle, and the writing on it had disappeared, but most of the sheepskin and the writing on it were still well preserved.

"Is it cement?" Yu Hongdou walked to the wall. She originally wanted to see the sheepskin and silk on the wall, but when she got to the wall, she found the gray wall.

She also said that with so many fellow villagers, it’s impossible that there isn’t one who makes cement.

"Cement?" The lyrics touched upon Tan Yanlin's blind spot in knowledge. He thought that Yu Hongdou saw it from the sheepskin on the wall.

When I walked behind her, I just saw her reaching out to touch the wall exposed where the felt was torn.

"A relatively strong building material." Yu Hongdou did not give a direct answer, but she did not hide it either. She only knew that cement was made of crushed stones, fired at high temperatures, and then mixed with something else.

She had no idea about the specific materials, proportions, or production methods.

Tan Yanlin seemed to be thinking about something but did not ask any more questions. He only looked at the sheepskin with relatively clear handwriting, pointed at one of the pieces and asked Yu Hongdou: "Can you understand it?"

When Yu Hongdou looked over, a string of complicated formulas came into view, making her dizzy.

"I only know a little bit." I only know the basics, but I have already returned the rest to the teacher.

But she could guess what these formulas were for without having to understand them.

From all the things that happened before, and... Yu Hongdou moved her gaze to the end, where there was a huge copper box.

On the copper box, a green label clearly reads [Raw Energy Stone].

Yu Hongdou passed the two test tables and walked straight to the back, but stopped in front of an object covered with a black cloth.

She looked at the round black mask, then hesitantly reached out her hand and grabbed a handful in the air.

[Sign-in location: For scrapped parts, do you need to spend 5 points to sign in? ]

[Successful sign-in: Obtained 1 energy reactor. ]

Yu Hongdou's hand froze in mid-air for a moment, and then she reached out to pull at the black cloth cover that was made of some unknown fur.

"Let me do it." Tan Yanlin took the first step and lifted the cloth cover before her.

The two of them took a breath at the same time and took two steps back in an instant.

"It's so scary~" Yu Hongdou touched his head to make sure his soul was still there.

She was mentally prepared. Usually in such an environment, the things being covered would be either dazzlingly beautiful, extremely ugly, or... terrifyingly frightening.

She was almost scared to death.

Under the black cloth is a round crystal ball. The ball is so black that even when a candle is shone on it, it does not refract any light.

And in the middle of this pure black there is a golden eye floating.

That’s right, it’s the eyes, the standard almond-shaped eyes with a round black pupil in the middle, which looks like a dark round hole.

Yu Hongdou frowned, endured the uncomfortable feeling all over, stretched out her finger, and poked her pupil through her sleeve, and it was solid.

"It doesn't look like they are one. There's a hint of gold in the black." Tan Yanlin pulled her hand back and put the candle close to his pupil. A ray of fire and two blurry figures gradually appeared on his pupil.

Yu Hongdou opened the system panel and only looked at the last grid behind the system. A round, pitch-black crystal ball was silently lying there, like an exquisite crystal ball.

[Energy Reactor (intact): A device that can stimulate energy stones. ]

How could they reproduce a perfect one?

As Yu Hongdou read the introduction, the weird feeling became stronger and stronger. She had a feeling that although the system did not do anything, it was still pushing her in a strange direction.

But she couldn't care too much about it now. She had no choice anyway. Yu Hongdou was about to close the system panel when her eyes suddenly swept across a flash of white.

She was stunned for a moment, staring at the night pearl in the grid that was signed from the ancestor of the Peng family, and had a bold guess in her mind.

Yu Hongdou looked up at Tan Yanlin and said, "Will this place also be sealed or destroyed after we get out?"

Tan Yanlin watched her change from a dazed state to a bright look, and as he recalled the past few times, he had already realized something in his mind. He was afraid that she could see things that ordinary people could not.

"Of course, some things are not suitable for too many people to know." He pretended that he had discovered nothing and answered Yu Hongdou's question seriously.

"Will the sealed person continue to search for the truth?" Yu Hongdou continued to ask, although she knew that Tan Yanlin might not know the answer.

"Yes, one is for protection, and the other is greed." Tan Yanlin told the truth. No emperor could really stay out of matters involving the "immortals".

"Oh..." Yu Hongdou responded and fell silent.

Tan Yanlin also remained silent for a moment, then suddenly asked, "What are you thinking about?"

Yu Hongdou raised her head and looked directly at the boy who was a head and a half taller than her. She felt conflicted when she saw that his eyes were calm and he showed no sign of panic or fear.

Tan Yanlin was not in a hurry. He just looked into her eyes and waited for her to figure it out.

In Yu Hongdou's heart, two little red beans were fighting each other:

White Red Bean: I don’t care about the hat fairy or the flying fairy from the sky. It has nothing to do with you. Now you just need to be an innocent little girl waiting to be rescued.

Black Red Bean: What are you thinking about? Is this something you can just give up? If you could, you wouldn't be trapped here. Everything is destined, and you are destined!

White Red Bean: Bullshit! Nothing is difficult in this world. As long as you are willing to give up, you can still be that ignorant little girl in ancient times, work hard in farming and business, and become a pure heroine.

Black Red Bean: Hehehe, you’re just wishful thinking. If this is really a story where the heroine is the main character and does farm work, then why would I give you a system?

What does the system... do? Yu Hongdou thought about this question seriously for the first time. What did the system bring to her? What did the system want her to do?

Could the purpose of the system be related to everything that has been discovered so far?
