Sign in and get rich in farming

Yu Hongdou looked at Yueming who had already walked to the edge of the small pond, opened the system interface and quickly took a look in her backpack.

The first thing that caught her eye was a colorful scene. Yu Hongdou blinked and then saw clearly that the brilliant color represented a dagger in the last three compartments of the backpack.

The dagger is sharp at the front and curved at the back. The base of the dagger near the handle is decorated with blue patterns, and red and green gems are inlaid on the patterns.

The gorgeous burnt blue pattern spreads back to cover the entire handle. On the front of the handle is a pair of pink tourmalines, and on the top of the handle is an emerald as big as a fingernail.

This dagger is so gorgeous! Yu Hongdou's eyes were almost straight. She signed in and got many things, but the most dazzling thing was probably the dagger in front of her, except for the Duobao Ruyi.

Even in the same backpack, this dagger is more eye-catching than the Ruyi, simply because the burnt blue color is brighter than the gold!

Although she was tempted, Yu Hongdou still remembered to warn herself and to hold back as this was a matter of life and death.

She moved her eyes to the other two backpack compartments and caught a glimpse of "Chen's Notes". The cover of the notebook was written in small regular script, and the handwriting was elegant and soft.

Although it was written as "Chen's Notes", the signature below was "Chen Xing Taoist".

It seems that this favored concubine also misses the past when she lived with her master and senior brothers.

When I opened the cover, I saw a short preface. In the preface, Chen did not describe too much about herself, but instead wrote about the injustice and malice of the world towards women.

Chen wrote that if women had the opportunity to learn to read and write, debate, travel, and broaden their horizons, they would be able to do no worse than men. In fact, because women are more attentive, their achievements in certain areas may even surpass those of men.

The preface is straightforward and sharp, and one can tell that Chen has a somewhat cynical mindset.

The sarcastic remark and the profound mockery in every word made Yu Hongdou's blood boil and he felt admiration for her.

Judging from this preface alone, Chen can be regarded as a pioneer of female awakening in this era.

Yu Hongdou quickly read the preface twice, savored it twice, and then turned to the main text.

In the main text, Chen did not mention her legendary story of how she suffered, rose up, dominated the last emperor's harem and escaped safely. Instead, she used a soothing prose-like tone to mention the rising and setting of the sun and the moon, and the positions and appearance patterns of the stars.

Yu Hongdou widened her eyes in surprise and quickly flipped through the book, only to find that it was actually a notebook of "scientific common sense" written by Chen!

The book is divided into several chapters. The first chapter talks about nature. It simply explains the sun, moon and stars, and teaches people how to find directions, judge time, and even predict weather based on the sun, moon and stars.

Chapter 2 talks about the weather, and describes some signs of the coming of wind, frost, rain and snow, as well as how to avoid and use lightning.

This section is interesting. Chen gives examples on how to properly attract lightning, how to place flammable materials at the place where lightning strikes, how to set a fire through lightning, how to save yourself during a fire caused by lightning, etc.

Combined with what she had heard from her brother before, that the Chen family, to which Chen was descended, was destroyed by a thunderstorm, Yu Hongdou reasonably suspected that this paragraph was an example given by Chen himself of his own thoughts and actions.

"Miss~" Yueming had already found a seat. When he turned around, he found that the young lady was gone. He was shocked. When he looked back again, he found that the young lady was standing on the side of the road in a daze.

"Hey~ here I come." Yu Hongdou was brought back to her senses by Yueming. She suddenly remembered where she was standing. She responded and turned over a few times hurriedly.

When she saw the words "one nitre, two yellows, three charcoal" written on the back of the notes, she couldn't help but pause for a moment. She glanced at the notes and was so shocked that her eyes almost popped out of their sockets.

Oh my god, Chen is actually a chemical engineer, no, a scientific genius!

This chapter actually describes how to make and increase the power of gunpowder.

Firecrackers actually already exist today, but they are mainly used in auspicious and festive ceremonies.

Teacher Mo told Yu Hongdou the day before yesterday that he once used the explosion of firecrackers to activate a mechanism, and used the sound to set up a formation and a trap to divert attention.

What Chen described in her notes were not firecrackers, but real gunpowder. She even wrote that sugar could be used to increase the power of the explosion!

Although he knew that gunpowder was the greatest weapon for time travelers, to Yu Hongdou it was not as useful as a record about saltpeter mixed in the description of gunpowder.

"Salt stone is wall frost. When the weather is clear and crisp in autumn, cover the ground and wall corners with it, add water to soak it, filter it, boil it and dry it in the sun to make crystals. The crystals of salt stone can dissolve in water and become ice."

When seeing this sentence, Yu Hongdou wanted to jump up and kiss this Chen's notebook!

She said, why does it feel like something is missing?

The weather has been gradually getting hotter. It may not be known elsewhere, but there is no one selling cold drinks in Wuan City right now.

When Yu Hongdou heard that the heroine's aunt opened a restaurant, she was looking forward to it. If she couldn't have ice cream, shaved ice would be fine.

She knew that saltpeter could be used to make ice, but Yu Hongdou couldn't remember where the saltpeter came from.

After all, saltpeter is rarely used in the daily lives of ordinary people.

Yu Hongdou closed the system interface, slowly grinned, and ran towards Yueming, wondering what kind of surprises Chen's notes would bring her.

When I walked over to Yueming, I suddenly remembered that there was one item I had not checked in. It would not be good to leave one of the three "unearthed" items behind...

Yu Hongdou glanced at Yueming who was putting corn balls into the gauze net, clicked on the system interface again, and hurriedly looked at the "Notes on Clearing Wrongs" in the last slot of the backpack.

"Every case must have cause and effect. Finding the external causes to unravel the internal situation, speaking up for the wronged, and redressing the grievances of the dead is the original intention of clearing up injustices..."

Yu Hongdou opened the notebook and was a little confused when she saw the first sentence of the preface. If she understood correctly, this was a notebook for solving criminal cases?

Her father had just been promoted to county lieutenant, and he let her get this notebook about criminal law and solving cases. It must be God's favor to her!

The crossbow in front has been discovered by her father and is no longer useful. She is worrying about what to give her father for his birthday!

It's like giving a pillow to someone who's falling asleep! Yu Hongdou smiled like a little mouse and decided to give this book to her father as a birthday present.

"Miss, look!" Yueming didn't know that the lady standing next to him had been distracted and wandered away, and was still excitedly pointing at the gauze for Yu Hongdou to see.

When Yu Hongdou closed the system interface again, seven or eight shrimps had already crawled into the gauze.

The water in Taoxi River is a little cold, and the shrimps are not big, the largest one is only half a finger long, and their bodies are transparent. They look delicious. Yu Hongdou, who had had enough fun, finally turned his attention back and drooled at the shrimps in the gauze net.

Take these small shrimps home, wash them twice with clean water, marinate them with onion, ginger, garlic, white wine and seasonings, and it is best to eat them raw.

The net is square, with straw sewn on the four sides and lines pulling the four corners. When the net is almost full of shrimps, the line is lifted up quickly, and the net breaks through the water...

"We caught him!" An excited shout came from the other end of the road, causing Yu Hongdou to ignore the gauze net in Yueming's hand and trot over there.
