I am cannon fodder, but I can hug thighs

"What's wrong with the girl?" Xunmian and Xing'er watched Lin Jin take out a bunch of poison and hidden weapons from the box, and then began to sigh.

Lin Jin curled her lips: "Fourteenth is going to the temple with her sister to worship Buddha. I always want to do it carefully and not let anything go wrong."

"I thought it was something else, but it turns out that the young lady is just worrying too much." Xunmian chuckled, "If Huguo Temple is not safe, then few places are safe. Besides, if the young ladies want to go to Huguo Temple, they must be accompanied by the family. They must bring the young ladies back safely."

But even so, Lin Jin was still uneasy, probably because of the death of the two girls. She always felt that it was a kind of reminder that even Song Shiqiu's territory was not completely safe and there would be omissions. Moreover, she had been very sensitive to such subtle changes since she was a child.

Some people call this the sixth sense or intuition, but she prefers to call it magnetic field.

"It's always better to be prepared." Lin Jin picked and chose a few more items, put all the medicines in her pouch, and a few bamboo arrows in her fan bag. Finally, her eyes fell on the exquisite little crossbow.

Although this small crossbow is more delicate than an ordinary crossbow, its shape does not make it convenient to carry. However, it is equivalent to three bamboo tube arrows. Lin Jin is reluctant to give up this essential self-defense weapon.

She picked up the small crossbow and looked at it for a long time, thinking about how to carry it without attracting too much attention. She wanted to see if it could be folded up. After pressing it carefully, she found that it could be folded up. The small crossbow looked like a wooden paperweight after being completely folded up.

Lin Jin: “!”

As expected of Tu Huaining, he can even make mechanisms.

You know, Lin Jin didn't actually have any hope at the beginning, but now it seems that Tu Huaining must have thought of it a long time ago. Such a thing is not suitable for being carried around outside, so he made this mechanism. If it is not used, no one will know what it is.

“Huaining, Huaining, you really are…” Lin Jin wanted to laugh but felt uncomfortable. On this journey to another world, she didn’t leave anything behind but she still owed so many people friendship. “You really surprise me every time.”

If the heroine didn't have the halo and system, no matter how smart she was, she would never be able to defeat Tu Huaining. Tu Huaining would not compete for the first place, but once he learned something, he would definitely learn it the best.

But how should she repay this love? From the beginning, she thought that Tu Huaining might be able to save Song Shixia. Later, it was because Tu Huaining could grow herbs. Later, she wanted Tu Huaining to be kind, but did Tu Huaining hope that she could do something?

Maybe not.

Because of the incident with the two maids, Lin Jin did not leave the Prime Minister's Mansion for several days. She just asked the housekeeper to help her check on the condition of the medicinal herbs in the medicine field every day. Then she began to think about how to improve the saline-alkali land.

She remembered that relevant knowledge was mentioned in junior high school chemistry and high school geography classes. Although it was not comprehensive, she knew the general steps.

Most saline-alkali lands are distributed in the north. Improving saline-alkali lands requires draining salt, but water resources in the north are relatively scarce, and it is difficult to implement without the South-to-North Water Diversion Project.

Groundwater exploitation. Lin Jin wrote these words and then crossed them out. Although this method is feasible, it is also inappropriate. If groundwater exploitation is successful, it will become a trend of this era, which will destroy the surface structure in advance and abuse water resources.

Seawater desalination technology. The ink spreads on the paper. Although it seems feasible and a simple distillation device can be made, she cannot guarantee whether the desalinated seawater can meet the requirements of improving saline-alkali land.

"Life is really like this, with every difficulty coming one by one, and the road ahead is long but also bright." Lin Jin held his forehead and smiled, his eyes full of fatigue and helplessness. But when he looked up at Xunmian and Xing'er who could always find something to do, he sighed and picked up a book beside him to read.

This is the introduction to mechanical engineering that she asked the housekeeper to bring back from Tianchunzhai these two days. Although we have not entered the mechanical age, perhaps we can get some ideas about the lost mechanical engineering in modern times.

Lin Jin put the book down as he read, called Xunmian and walked towards the Plum Courtyard.

Sometimes people still have to learn to make use of the resources around them. It is not enough to just bury their heads in hard work.

Lin Jin looked at Chunzao a little embarrassedly: "Sister, long time no see, how have you been during this period?"

"What are you doing here?" Chunzao looked at her coldly.

"I came to see how you are doing. Is there anything you need?" Lin Jin said sincerely. After all, she wanted to ask Chunzao for something, but she didn't want it for nothing. She wanted to exchange things with Chunzao. "Is there anything I can do to help you?"

Chunzao looked at Lin Jin sarcastically: "Then can you die?"

Lin Jin held down Xunmian who was about to speak, with a smile on her face: "My sister scared my Xunmian by saying this. Why does she keep talking about death? It's so unlucky. This kind of joke is not funny at all, baby."

"Aren't you disgusting? Who is your baby?" Chunzao looked disgusted, as if she was about to get goosebumps. "A weasel is paying New Year's greetings to a chicken. It has no good intentions."

"You can't say that. I have always been sincere. I am not that kind of person. If you say that, I will sue you for slander." Lin Jin did not admit it. Although she said she was not a good person, she had never done anything bad.

"Do you dare to say that you didn't come here to steal the things in my system?" Chunzao's eyes were filled with contempt. If the situation was not beyond her control, she would not have spoken to Lin Jin.

Lin Jin touched his nose. He couldn't refute this. It was really true: "Then I'll exchange something with you. Is that okay?"

"No!" Chunzao swore that she would not give in, "Unless you die."

Lin Jin choked, not knowing why this kid wanted her life so much: "I think you can reconsider it."

"That's fine, then you ask Song Shiqiu to let me go." Chunzao rolled her eyes.

Lin Jin: "Then you might as well let me die."

If this ancestor runs away, it will be a big disaster.

"Then why are you pretending in front of me?" Chunzao laughed at Lin Jin silently, looking at him as if he were a fool. "It seems that your status in Song Shiqiu's eyes is just like this, and your value is just this little bit."

Lin Jin disagreed with this, but she didn't argue with the kid: "Sister, we have always exchanged things for things, but you are exchanging conditions for things. This is so unfair. What's more, what I want is just a book. Your two requests are a bit too much."

"What book?" Chunzao narrowed her eyes. "You want the original novel? You're dreaming."

Lin Jin: "I really don't think much of this." She even has the manuscript sent to her by her bestie in her modern computer.

"Then what do you want?" Chunzao's eyes were full of suspicion, "Thirty-Six Strategies of Palace Fighting?"

Lin Jin laughed angrily: "Sister, your book list is a bit mixed."

What has this child watched?

Chunzao blushed a little at being laughed at: "So what do you want?"

"I want the theory and technology of planting and improving saline-alkali land." Lin Jin said what she wanted with a smile, "So sister, see if you can get it. I can exchange it with you for other things."

Chunzao frowned, but still looked at her system mall. There really was this book, but when she saw the five red nines in the redemption points column, she couldn't help but curse, "Why don't you go grab it!"

Why is such a crappy book so expensive?

Lin Jin was frightened and blinked: "Huh?"

Chunzao gritted her teeth. Even if she conquered Song Shiqiu, she would only get 100,000 points. This book was equivalent to her working in vain even after she conquered Song Shiqiu.

"No!" Chunzao glared at Lin Jin unhappily, "You did it on purpose, didn't you?"
