She only wants to do infrastructure construction

Chapter 10 Really Just Digging a Hole
Therefore, it is best not to use explosives, at least not before she establishes a safe haven. After all, explosives are one of the trump cards for self-protection.

However, Taihe Prefecture's iron smelting technology is not up to par. Without explosives, mines cannot be dug, and without gold, the debt problem cannot be solved, let alone the establishment of a dream town.

In summary, Li Yewu can only take the risk of adding explosives in advance.

According to the novel, he went to Xiao Jiuxi and never returned to the fiefdom until he died. If he was optimistic, as long as he was careful about the explosives and concealed it better, Xiao Jiuxi probably wouldn't know.

As long as he didn't know, the imperial capital would still be in chaos, whoever should die.

As long as it doesn't affect the direction of the story, it should be fine for her to blow up mountains here, right?

And to be honest, bandits and bandits are rampant here, and she really needs something to defend herself as a weak woman fighting against the five scum.

Not to mention anything else, carrying a few grenades with you is much safer than servants.

After all, you can only be a princess by relying on others, but you can be a queen by yourself.

All in all, Li Yewu was determined to toss the explosives.

When it comes to making soil explosives, how can an excellent infrastructure engineer not?

It is said that "one nitrate, two carbon and three sulfur" is the secret recipe for making explosives. In fact, there are many secret recipes for soil explosives. In addition to the above, there are other three most commonly used.

One is nitrate, sawdust, diesel; the second is nitrate, wheat sugar, sulfur; the third is nitrate, sawdust, and salt.

It can be seen from this that the core of soil explosives is nitrate.

Speaking of nitrate, it can not only be used as explosives, but also can be used to process animal hides and hairs for longer preservation, and can even be used as fertilizer to improve fertility, and soy milk can be used to make tofu, etc.

In ancient times, there were also specialized craftsmen who made a living by making and selling nitrate, and they were nitrate makers.

Of course, this is ancient China, and as far as the original owner's memory is concerned, there is no such occupation here.

Right now, as long as Li Yewu solves the nitric acid problem, the rest will be easy to handle.

The ancients generally boiled it in caves, because the soil in caves is rich in sulfate and nitrate, and the nitrate content will be greatly increased when boiling nitrate.

However, there are too many bandits around Taihe City, and it is obviously unrealistic to rush to the caves in the suburbs.

Li Yewu set his mind on the cave in Xiao Jiuxi's back garden.

……

Speaking of which, there is a rockery in the back garden of King Shang’s Mansion, and there is a culvert in the rockery. This culvert is amazing, and there are a pair of mandarin duck pools in it, one left, one right, one cold and one cold facing each other far away.

This is also Xiao Jiuxi's favorite place, soaking in hot springs in winter and cold springs in summer, not to mention enjoying it more.

At this time, Li Yewu, who had returned home to eat and drink, found Xiao Jiuxi's most precious place with a shovel on his back.

Zi Cui was also traveling with her.

Seeing that Li Yewu was about to dig a hole in the culvert, Zi Cui was very disturbed.

"Little madam, do you really want to do this? Will the master be unhappy?"

"Don't worry, I just dug a hole in the open space here, and I didn't fill in his hot spring. It's okay." Li Yewu replied very simply.

"But... if you want to soak in it, just go in, why bother digging another pool."

Of course, the most important thing is that although the master is easy-going, he is also picky. He pays attention to the ultimate symmetry in everything he does. Didn't you find that the size and position of the pool here are all symmetrical?
If the harmonious symmetry here is broken, I'm afraid the master will be furious.

Li Yewu raised his eyebrows: "You think I'm digging for fun? If it wasn't for paying him back, would I have to work so hard?
If I dig it now, I can pay back the money in a month. If I don’t dig it, Xiao Jiuxi won’t even be able to touch it in a month. Do you want to dig it or not? "

"Ah?" Zi Cui's eyes widened, dare the little lady is still trying to solve the master's affairs?

"I'm sorry, little lady. I was too stupid to see your good intentions. Now that I know, I will do my best to help you dig a hole together."

Now the whole family is working hard to pay off the master's debts. As the most heartfelt little girl, Zicui certainly can't hold her back.

Li Yewu couldn't help laughing at the little girl's ignorant appearance that day.

It is said that the ancients had many eyes, but it seems that this is not always the case.

Or in other words, it's just that the servants in Xiao Jiuxi's mansion are different, everyone is very simple and everyone is a talent.

After persuading Zi Cui, Li Yewu rolled up his sleeves and started digging holes.

Although Zi Cui didn't know that there was any necessary connection between digging a hole here and repaying the master's debt, but the old housekeeper said that everyone in the house must fully cooperate with the little lady, so she just cooperated.

Soon the two dug two large pits, the second of which was much deeper than the first.

Then Li Yewu told Zi Cui to go to the kitchen to straw, the more the better.

Zi Cui nodded without hesitation and ran away, when she came back with a large pile of straw, the little lady was busy working in the second pit.

Zi Cui went over to take a look, and saw that the little lady was digging out the cave, her hands and clothes were all muddy, and she was very embarrassed.

But the little lady didn't care at all, she climbed up slowly after dredging the two pits.

Seeing that Zi Cui came back, he gave her a bright smile: "You're back? Thank you for your hard work!"

Zi Cui was taken aback, this was the first time a master expressed kindness to her, it felt like her sister...

Zi Cui pursed her lips in embarrassment and smiled, shaking her head silently: "It's not hard work, Zi Cui should do it."

"Okay, let's continue!"

Li Yewu nodded at her, picked up the shovel again and filled the first pit with straw, one layer of straw and one layer of soil, tamping back and forth and repeating.

Zicui understood and helped.

About half an hour later, the big hole dug by the two of them was filled back again.

After that, Li Yewu took a wooden bucket and began to pour water into the filled pit layer by layer. After watering four or five times, she made sure that the soil layer was completely drenched, and then she was ready to go back to the house.

"Little lady, what are we going to do?"

Now Zicui is even more puzzled by Monk Zhanger.

At first I thought my wife was going to dig a hole to soak in the hot springs, but later I thought my wife was going to be an organ, but after a long time, my wife just wanted to bury straw?
Li Yewu smiled mysteriously: "You will know in the future, go to rest quickly, and we will come back when we are young."

"Is Zishi still coming?"

Zi Cui's curiosity is completely full, but Li Yewu is determined to keep it mysterious, Zi Cui can only give up.

But also because she was so curious, Zi Cui didn't rest for a moment. When it was midnight, she ran to call Li Yewu like a bird telling the time.

The master and servant set out to the backyard again with lanterns lit.

Although the Shangwang Mansion has bare walls, the framework here is still there, the garden and corridors are all available, and there is still a certain distance between the two of them from the bedroom to the cave in the back mountain.

Walking in the corridor with a lantern, you can still hear the chirping of insects and birds around you, which feels quite quiet and deep.

Although the moonlit night is beautiful, honestly, without Zi Cui by her side, she would really feel scared.
