There is no soap in this world.

For the cleaning of clothes, it is common to wrap them in water and rub them with stones.

This is extremely damaging to the clothes and the stain removal effect is not ideal.

But if there is soap, it is very different!

The soap is very easy to make.

Simply mix the lard, salt, and alkaline plants (plant ash) and cook them until they cool and form.

Qin Zhen immediately ran to the back kitchen and began to operate.

"Eungong, what are you doing?" Xiao Daiyu followed Qin Zhen like a curious baby, and watched Qin Zhen tinkering around, feeling very novel.

"I'm making something that I can wash my clothes clean." Qin Zhen stirred in the boiling pot with a wooden stick while explaining: "That is, the soap I talked about before, with this thing, no matter how dirty the clothes are, they can look new." ”

"Is there such a thing as magical?" Little Daiyu was surprised.

"Not before, but now there is." Qin Zhen was quite excited, and his previous tiredness was swept away.

Doing laundry is tantamount to just needing!

Any business related to rigid needs is naturally a million profits!

You can imagine what it would be like for those people who were worried about the difficulty of washing their clothes when they found soap that could effectively clean their clothes! The key is that this thing can not only be used to wash clothes, but also to clean itself, with nectar, it is a completely natural perfume.

Other Qin Zhen didn't dare to guarantee it, but a lady like Miss Ying'er would definitely go crazy about it.

It took a night of boiling with his eyes open before the soap solidified.

Looking at Huang Cancan's soap like a brick, Xiao Daiyu's face was full of suspicion.

"Can this thing really wash clothes?"

"Just try it."

As he spoke, Qin Zhen picked up the tattered and filthy black clothes, and used soap to pour hot water, and soon the filth on it was cleaned up, revealing a white bottom silk.

"You're dressed in white?" Qin Zhen was shocked.

That's too much!

"Wow! You can really wash it off! Xiao Daiyu tried it herself, watching the unrecognizable clothes gradually return to its original face, she was excited in her heart, and she was even more grateful to Qin Zhen.

"The first time I made soap, I was still a little rusty. When I research and research, find a way to get a mold, and then add some nectar or something to make some fragrance out, this thing will definitely sell! Qin Zhen seemed to have seen a steady stream of gold pouring towards him.

"Engong, you know so much!" Xiao Daiyu's eyes were sparkling and full of adoration.

"I just knew about it before you, and now you know it too." Qin Zhen didn't think that there was anything great about being able to make soap, he was just standing on the shoulders of giants.

"Engong, this must not be known to others." Xiao Daiyu's immature cheeks flashed with a mature brilliance, and she knew the truth of her guilt.

Years of suffering have already tempered her mind, don't look at her young age, but her mind is already mature.

"I'll leave it to you."

"Me?" Xiao Daiyu's mouth opened wide.

"You want to get a batch of samples out these days, and I will ask Li Han to help you."

Qin Zhen, who hadn't slept all night, was sleepy at the moment, turned around with a yawn, and staggered upstairs to sleep.

Only Xiao Daiyu was left alone in a daze facing the soap.

How could Qin Zhen not know the importance of soap?

This trust flattered Xiao Daiyu.

She waved her pink fist and made up her mind: "Engong, just look at it, I won't let you down!" ”

Qin Zhen slept until the afternoon.

When he woke up, the inn was empty, and it was estimated that Li Han had taken everyone out to set up a stall.

He was just about to go to the back kitchen to find something to eat when he saw a thin figure squatting in front of the soup pot and staggering.

He hurriedly ran over, pulled Xiao Daiyu up, and blamed him with a dark face: "Go back to sleep when you're tired, put this shaking your head and shaking your head, aren't you afraid of falling into the pot?" ”

Xiao Daiyu rubbed her eyes in a daze, a little embarrassed.

"Go back to sleep, I'll keep an eye on it."

Qin Zhen waved his hand and sent Xiao Daiyu away.

I started tinkering, thinking about how to add flavor to the soap and turn it into soap.

Qin Zhen is just an ordinary person, with limited knowledge and can't cover everything, so he has no experience in this area.

It seems that because of hunger, the extraction of the fragrance made him instinctively think of the picture of boiling the hot pot base in the small video.

The base chef will put the green onions, ginger and other vegetables into the oil pan to squeeze and cook, and after frying dry, remove them, and the remaining oil will have the fragrance of the vegetables.

"Why don't I put the spices in the pot and cook them together?"

Qin Zhen muttered, and was about to try it, when he suddenly wanted to slap himself.

"Hot pot! I can still make hot pot! ”

How did you forget that hot pot is so profitable?

Fishing at the bottom of the whole lake, massaging the foot bath and listening to the drama on the street, can you still make money?

In fact, it's no wonder that Qin Zhen is not surprising.

After all, I was so poor before, and the wild vegetables were on the Guanyin soil every day, and I forgot what the meat tasted like, how could I think of this?

Of course, this has to be considered in the long run.

But in Qin Zhen's heart, a wildfire of being a business tycoon has already been ignited.

At this time, Xiao Qingwen walked over.

Compared with Daiyu, Xiao Qingwen is obviously a lot more innocent, her pink and fair face is timid, and she is still a doll with a childish voice.

"Engong, my sister asked me to help you."

Looking at the little doll that was not as high as the stove, Qin Zhen couldn't help but laugh.

"Go back and stay, don't make a mess."

"No, no, my sister will talk about me when I go back." Xiao Qingwen pouted and prayed: "Engong just let me stay here, I promise to be obedient and not add to the chaos." ”

Who can bear to refuse the request of such a simple and cute little girl?

"Okay, sit farther away, don't get splashed by the hot soup in the pot."

Xiao Qingwen obediently moved a small stool and sat down, and couldn't help but look into the pot.

"Engong, what's in the pot? It smells so good. ”

"Soap."

"What's soap?"

One big and one small are communicating, Xiao Qingwen is like a curious baby, chattering a little noisy, but it will not make Qin Zhen feel bored.

"Don't call me in the future, it sounds weird, I'm not much older than you, you can just call me brother in the future." Qin Zhen scratched his head.

"Brother?" Xiao Qingwen tilted her head, and her serious thinking looked very cute.

As if thinking of something, Xiao Qingwen hurriedly shook her head and said in a childish voice.

"No, my sister said that we are Engong's maids, we want to make cattle and horses for Engong, we must respect Engong, and we will serve Engong for the rest of our lives! How can you call Eun Gong your brother? ”
