Sign in and get rich in farming

From the time she traveled through time until now, the system hasn't brought her much help, but it can't be said to be completely useless. After all, her brother and father's future depended on the system's sign-in.

Up to now, there seemed to be no trace, but when she thought about it carefully, it seemed that the system was really pushing her step by step.

Tan Yanlin didn't say anything. He watched the little girl close her eyes, frown, and roll her eyeballs back and forth under her eyelids, proving that she was thinking and struggling hard.

After a moment, Yu Hongdou opened her eyes and looked at Tan Yanlin intently: "Since everyone is looking for the truth, why can't it be us?"

Yes, why couldn't it be them, why couldn't it be her?

She wanted to know why she came into this world.

Did the original little red bean travel to another world, or did it merge with her?

Is this a world derived from "Tian Yi Man Man" or is it an independent world?

What was the final outcome of the fellow villager of the chemistry graduate student? Did he return home or die in this foreign land?

Yu Hongdou looked at Tan Yanlin with burning eyes. She had to find a partner, someone with background, brains and strength, to work together to deduce and find the truth of the events that were lost in history but left traces to attract people to look for them.

"I once read a sentence in an ancient book, which said: One must do something great in his life to prove that he has been here."

Tan Yanlin smiled and slowly extended his hand towards Yu Hongdou.

Yu Hongdou tilted her head and looked at his outstretched hand. She always felt that it was a bit strange, but she didn't think much about it and just clapped her hand over: "Deal!"

"So what should we do next?" Tan Yanlin withdrew his numb palm and pointed into the room.

"You find the exit, and I'll take a look at this." Yu Hongdou divided the work without any hesitation. They had been delayed here for too long, and she was afraid that her brother would collapse.

Tan Yanlin agreed and lit a candle and handed it to her. He didn't go far, but just searched around about three steps away from her.

Yu Hongdou walked to the place where the energy stone was, suppressed the uneasy feeling in her heart, looked at the 50 points after the mark, and sighed softly.

In addition to upgrading her skills, she accumulated points by doing one point a day.

She had consumed some energy in Yunruo Temple before, and she wanted to have a chance to collect some more nectar pills for her family. Moreover, she had not signed in with several Bodhisattvas in the temple, so she didn't know if they would give her any incredible treasures.

Another thing is that she has never been to a larger Taoist temple. If she were to go before the Three Pure Ones and the Four Emperors, she would have to try and see what the Taoists could give her.

So she tried to save as much as she could, just to keep some points in case of an emergency, because she still hadn't signed in for the black stone she got from the Peng family.

But the one in front of her must be signed. Yu Hongdou is 80% sure that this energy stone can give her a usable energy stone.

[Sign in successfully: Obtain 100g of energy stone. ]

Sure enough, Yu Hongdou took a look at the harvest, then looked at the light column, and found that it had not turned into a grayish white color that could no longer be signed in, nor had it turned into a light yellow color that was in a cooling state.

Above the brass box, there was still a faint, flickering green beam of light floating.

Yu Hongdou glanced at the points and touched the sign-in icon.

[Sign in successfully: Obtain 100g of energy stone. ]

Huh? It hasn't changed color yet!

Yu Hongdou gritted her teeth, raised her hand and started to touch, signing in four times in a row and obtaining a total of 400g of energy stones.

The green beam of light finally disappeared and turned into a grayish white.

Yu Hongdou looked at the square, shiny copper box without any pattern.

The creepy feeling she had just had when she stood in front of the box disappeared without a trace. She had a hunch that the energy stones inside were completely scrapped.

"There is a notebook here, and there is a door." Tan Yanlin also made a discovery.

He found a secret door under Taoist Changlin's laboratory table. When he bent down, he saw a black leather notebook stuck to the bottom of the table.

"..." Yu Hongdou took it curiously. So is this notebook distributed uniformly in the Hat Fairy Classroom?

When I opened the notebook, I saw beautiful small regular script inside. The handwriting clearly recorded the mental journey of a pure ancient person learning mathematics, physics and chemistry, especially advanced chemistry.

Mixed in between were two torn pieces of mounted paper, on which were scribbled the periodic table and some discontinuous formulas.

"I think this is what Mi Sheng got." Tan Yanlin said with certainty.

Yu Hongdou flipped through the book from front to back and was disappointed to find that it was indeed a study notebook. However, when she touched the leather cover of the notebook with the same feel, she understood.

"It seems that Master Changlin finally met the Hat Fairy and received some guidance." Yu Hongdou's tone was even more certain than Tan Yanlin's just now.

The two smiled at each other, and the timeline and character lines of the Hat Fairy gradually became clear. They just needed to find time to sort them out after they got out, and the truth would almost come to light.

"I'm afraid this door is not the way out." Yu Hongdou sat on the floor with a notebook in her hand, looking at the square door under the table.

Tan Yanlin didn't say anything. He just squatted down and crawled under the table, then raised his hand to knock on the small door.

The empty sound made the two realize that there was indeed an empty space behind the small door.

Yu Hongdou watched Tan Yanlin take out the fancy dagger again, and after hesitating for a while, she finally asked, "How did you lose the other half of your dagger?"

Tan Yanlin paused for a moment and looked back at her. He knew that she must have a reason for asking this question. It was likely that she had seen or knew the whereabouts of the other dagger.

"My maternal grandfather's family is considered an aristocratic family. Tracing back to the roots, there were famous people in the past three dynasties. The original name of this dagger was the Mandarin Duck Dagger. As the name suggests, it is a pair."

After saying this, Tan Yanlin turned around and continued to pry open the small door without stopping.

"The Mandarin Duck Daggers were a pair of lovers' daggers made by an outstanding ancestor of the clan in the previous dynasty as a token of love."

"This ancestor loved his wife all his life, but they only had one daughter, so he passed the dagger to his beloved daughter. This female ancestor was a chivalrous woman in the martial arts world. When she was traveling in the martial arts world, she met her beloved, so she gave the mandarin duck dagger to him as a token of love."

"Unexpectedly, an accident separated the two. The man took the mandarin duck dagger and disappeared in the vast sea of ​​people. The mandarin duck lost its partner. The female ancestor searched for half her life and died in depression. The famous token of love in the ancestor really became an ordinary self-defense dagger."

Tan Yanlin finished speaking in one breath, then turned back and smiled at Yu Hongdou: "If nothing else, it's quite useful."

As soon as he finished speaking, the square door popped open, revealing a dark hole inside. The wind was howling, as if there was a monster hiding inside and was about to rush out.

Yu Hongdou took a look with a tingling scalp, and was about to reach something in to take a look, but suddenly she saw a dark shadow emerging from the hole.
