I am cannon fodder, but I can hug thighs

Lin Jin felt numb inside and sighed heavily: "Let's talk it over nicely. Brother, put down your sword first."

After Liu Zhengqing put away his sword, Fang Zhining immediately came out from behind Lin Jin and said to him, "I also need your Gu worm to save my life this time."

"No help!" Liu Zhengqing shook his sleeves. It was not easy to raise his poisonous insect, so how could he give it to Fang Zhining so easily.

"Then I can't tell you where to dig a well to find water." Fang Zhining had an expression of being afraid of everyone else.

Liu Zhengqing said indifferently: "It's not my people who died."

Lin Jin: “…”

I want to persuade him, but I dare not.

"I really thought you would become a better person after serving as an official for a few years. Why are you still so cold-blooded?" Fang Zhining really didn't expect Liu Zhengqing to say such a thing. "I came all the way from Jiaozhou. If these two options don't work, then this one option, just one option."

Fang Zhining raised a finger, trying to exchange it for a poisonous insect from Liu Zhengqing.

Liu Zhengqing glanced at her suspiciously: "Who is so important that you would be so humble to him?"

"It's not that the patient is important, it's mainly because of her noble status." Fang Zhining showed a bit of worry on his face, "If I can't cure her, I might lose my head."

"Keep making it up." Liu Zhengqing sighed. He didn't believe a word of the second half of the sentence. "How could I not know what important figures there are in Jiaozhou?"

Most of Jiaozhou is poor, and no one would want to go to Jiaozhou.

Fang Zhining chuckled twice. She really wasn't making this up: "Have you forgotten Princess Jing'an who is studying abroad?"

No matter what Liu Zhengqing said, he was unwilling to give his Gu worm to Fang Zhining. After all, his previous Gu King had been used as medicine. He had raised a new Gu King with great difficulty, so how could he give it to Fang Zhining for use as medicine?

"We must have the poisonous insect. Can't we use something else?" Lin Jin really wanted to dig a deep well.

"No, that disease is difficult to cure. Only his poisonous insects can be used as a medicine." If Fang Zhining could find something else, he would not come to Liu Zhengqing to ask for the poisonous insects.

Liu Zhengqing folded his arms and stood like a pine tree: "No."

"It's just saving a life. There are so many causes and consequences in the world. What if your kindness this time saves your future self?" Fang Zhining advised Liu Zhengqing earnestly, "It's just a poisonous insect. It's no big deal..."

She gritted her teeth and said, "I'll give you all the herbs I grow in my herb garden to use for breeding Gu!"

"Deal." Liu Zhengqing took out a bamboo tube from his sleeve pocket and threw it to Fang Zhining.

Fang Zhining quickly took it and nodded at him: "You are really, really a profiteer."

She definitely suffered a loss, otherwise Liu Zhengqing would not have been so straightforward.

"What you said is really interesting. You said it yourself. I didn't force you, but in the end I'm accused of being a profiteer." Liu Zhengqing's tone was full of sarcasm, and his words implied that Fang Zhining was being unreasonable.

Fang Zhining gritted his teeth and could not speak. He could only tell them where to dig the well according to the agreement: "But let me say this in advance. According to my experience, although digging a well here can provide water, you have to dig it at least 40 to 50 meters deep."

No well digger in Daxia had ever dug such a deep well.

Lin Jin had anticipated this result, so during this period she estimated the depth to be fifty to sixty meters. Although she had never drilled such a deep well before, it was not impossible to give it a try.

Now that she knew the place, Lin Jin took the opportunity to prepare the tools for digging the well and for protection while Liu Zhengqing took people to look at the terrain. Safety helmets were definitely necessary, as well as lights and the like.

The well diggers have been digging wells for so many years, but this is the first time they have heard of digging a well that is forty or fifty meters deep. The deeper the well, the more dangerous it is. However, the group of people gritted their teeth and decided to start digging after thinking about getting water.

"But even if water is dug out of the well, you can't pump it out." Fang Zhining frowned, always feeling that they were too naive. Even if there was water, it had to be used. If the water was found but couldn't be pumped out, that would be truly hopeless.

"Don't worry about it. This is not your business." Liu Zhengqing replied to her bluntly.

"You don't know good people's hearts."

Lin Jin naturally knew that it was difficult to draw water from a deep well, so she got out the pumps for the water pressure well. After systematic testing, they were completely usable. She is now drawing the blueprints of the water pressure well and will have it built next to the well.

We have finally found a place where we can pump out groundwater. We cannot fail here.

The well digger dug a well for several days, but he didn't see any water until he reached a depth of more than 40 meters underground. "It doesn't look like there is water here. We are already more than 40 meters deep, almost 50 meters. If there is water, the mud can't be so dry."

The mouth of this well is two or three times larger than the previous wells dug, and it's dug so deep, but there's not even a drop of water to be seen. Isn't this just a hassle?

Liu Zhengqing looked at Fang Zhining: "There is no water."

"Impossible, there must be water. Dig another ten meters down, and you will definitely find water at most." Fang Zhining's face froze for a moment, and then he was very confident in his experience, "Big Brother, just dig another ten meters, there must be water."

Liu Zhengqing took a deep breath and said, "Listen to her and keep digging."

The well digger glanced at Fang Zhining, then looked at the bottomless well mouth: "Forget it, we have already dug more than 40 meters, so another 10 meters won't make a difference!"

If water could really be dug out, the people of Taiyuan Prefecture would be saved.

As evening approached, Lin Jin had people carry specially made iron pipes and cement powder over here: "Did you find any water? I have everything ready."

Just as Liu Zhengqing was about to say "no" he heard some movement from below. The others quickly pulled up the well digger with ropes: "Water, we found water! There is really water below!"

Fang Zhining breathed a sigh of relief. Her father's reputation was saved. She raised her chin towards Liu Zhengqing and said, "I am definitely honest and I can't lie to you."

"You still haven't settled the score for deceiving me half a year ago." Liu Zhengqing reminded her not to forget that there was the life of the Gu King between them.

Fang Zhining secretly moved a few steps towards Lin Jin and quickly changed the subject: "What is this gray thing?"

"This is cement. It's used to make a water pressure well." Lin Jin spread out the blueprint and showed them the internal structure of the water pressure well. "Just make it like this, and then you can use the water pressure well to pump water up directly."

The structure of a water pressure well is actually very simple and not difficult. Most of the people here are veterans. Although they have never used the cement that Lin Jin mentioned, they quickly mastered the skills with Lin Jin's guidance.

A water pressure well was quickly repaired. Fang Zhining looked at the so-called water pressure well and asked, "Can this pump water up?"

"Yes, but we have to wait a few days for the cement to dry, otherwise it will easily fall over." Lin Jin only got the cement powder out today, otherwise he would have brought people over to repair the well a few days ago.

Fang Zhining looked at the remaining wet cement on the ground and twisted it with his hand: "It seems to be no different from mud except that it is a little darker."

"The difference is huge. You'll know in a few days." Lin Jin looked at her seriously. "The wall built with this thing and red bricks is very strong. The road built with it is also strong. It's different from a mud road. Even if there is heavy rain, the road surface will not become muddy and difficult to walk on."

"It's so magical, do you still have this thing?" Fang Zhining thought of the road to the Valley of Divine Doctors, and she didn't want to say anything more. People said that the Valley of Divine Doctors was a paradise on earth, but only they themselves knew how difficult that road was to walk on.

"I've only made this little bit in a few days." Lin Jin didn't plan to make this thing anymore. "I still have the recipe, but I don't have more raw materials."

If you want to make this cement again, you have to find the raw materials. What the system provides is not enough.

Fang Zhining stretched out his hands and blinked: "Beautiful, kind, smart and witty Lady Liu Jin, can you give me a copy? I can buy it from you!"

Lin Jin: “Uh…”

This lackey is... the Immortal Doctor?
