Martial arts: A Taoist friend, Li Mochou cried

The older policeman who spoke just now said with a smile: "My lord, this subordinate is from Dengpingfang. He once drank with Mr. Zhang's father. You can be sure that he is a native of Lin'an, and he is definitely not an accomplice of the murderer. .”

When speaking of the word 'native-born', the elder policeman's tone was full of pride.

It's no wonder that Lin'an is the capital of the Song Dynasty, and the people in the city are naturally proud of it at the foot of the Son of Heaven.

Even Tie Shou, in the eyes of many of the six gates, is nothing more than an officer transferred from another place.

At this time, Tie Shou was also quite helpless. Even though he was strong in martial arts and meticulous in thinking, he was not a god after all, and it was impossible to rely on him to track down the murderer alone.

But the gang of detectives under him can't count on it at all.

The main reason is that most of these arrests are locals from Lin'an.

It is simply unrealistic for them to search for the murderer from house to house, and it is probably just going through the motions.

After all, we are neighbors in the neighborhood, and the clan power is deeply intertwined. If we really want to conduct a large-scale search, these policemen will inevitably suffer from the eyes and gossip of the neighbors after they return home.

Tieshou couldn't help but sighed.

Fortunately, Granny Jinhua killed all people in the Jianghu, and the six gates classified this case as a Jianghu vendetta.

If ordinary people were killed, the case would be rather troublesome.

Right now, he can only temporarily put the case aside.

After all, there were too many cases in Six Doors, and he didn't have the energy to spend on this matter all the time.

As long as Grandma Jinhua shows up in Lin'an City, with the large number of spies from the six gates, she will never have a chance to escape.

"Son, what are you doing?"

Seeing Zhang Chu holding a pot of lard, Yin Li showed curiosity on his face.

She originally thought that Zhang Chu asked her to buy lard to make delicious food.

From the looks of it, it doesn't seem to be for eating.

"Make soap." Zhang Chu casually poured lard into the plant ash solution and replied while stirring.

"Soap?" Yin Li couldn't help being startled, apparently hearing this word for the first time.

Zhang Chu smiled and said, “You will know later.”

As the saying goes, there are three treasures in time travel, cement, glass and soap.

These three things are easy to make as long as you have basic chemical knowledge.

Among them, the soap is simpler, and the original soap can be made by mixing animal fat with plant ash.

Although the appearance is not necessarily good-looking, the decontamination effect is very good, at least much better than saponins.

Zhang Chu worked hard for a long time, and finally poured the mixed solution into the mold, and added some milk, so that it was a real soap.

Next, just wait for the solution to cool.

In the morning of the next day, Zhang Chu casually threw a piece of made soap to Yin Li.

"My lord, is this the soap you mentioned? What's its use?" Yin Li asked curiously, looking at the soap in his hand.

Zhang Chu laughed and said, "This is weak alkaline soap. You can wash clothes or wash your hands and take a bath."

"..."

Yin Li's face turned slightly red.

Seriously, young master, how could he ask for a bath in front of a woman at will.

But she soon became happy again. It would be great if this thing could really wash clothes, although she didn't understand what weak alkaline soap was.

Now Yin Li is most worried about washing clothes every day.

Ordinary linen clothes are fine, you can go to the river and beat them with wooden sticks.

This is the most common way of cleaning clothes in ancient times. Through the action of external force, the dirt or bacteria in the clothes are thrown out.

But if it is silk clothes, this method cannot be used, because silk fabrics are relatively fragile and can only be cleaned carefully by hand.

Now that there is another Dai Qisi, Yin Li spends a lot of time washing clothes every day.

Yin Li took the soap and came to the well, ready to try Zhang Chu's homemade soap.

Soon Yin Li discovered that not only the stains on the clothes were easily cleaned by her, and it became as clean as new, even her hands that washed the clothes became clean.

Yin Li admired Zhang Chu very much.

Unexpectedly, the young master has this ability.

…………

In the study, Zhang Chu looked at the soap in his hand, hesitating whether to sell it or not.

But he soon dismissed the idea.

There is no patent protection these days, and once the soap spreads to the market, it is estimated that it will be imitated by some big merchants soon.

At that time, he will not earn any money at all.

Forget it, let's think of other ways to make money.

【Ding!Task release: Open a store, unlimited categories]

[Mission reward: a piece of super protective clothing! 】

Hearing the long-lost system prompt in his mind, Zhang Chu couldn't help being slightly taken aback.

There seems to be something wrong with the painting style of this mission reward.

Chapter 11 The Mathematical Little Beggar

Originally, Zhang Chu thought that he would reward some kind of magic skill, such as King Kong’s indestructible magic skill, innate stellar energy and so on.

But I didn't expect to give a body protection item.

But Zhang Chu thought about it again, and this thing seems to be good.

You don't need to practice, and you won't be seen by others. What you pay attention to is a low profile.

Zhang Chu turned his thoughts to the task again.

It is not difficult to open a shop.

And you can earn some money by the way.

However, what kind of shop is better?

Zhang Chu pondered for a moment, and finally had an idea in his mind.

Just open a hot pot restaurant and forget it.

Thinking of this, Zhang Chu immediately took out a pen and paper, wrote the words 'recruitment shopkeeper' on it, and hung it outside the house.

"My lord, what do you want to recruit the shopkeeper for?" Yin Li asked puzzledly when he saw Zhang Chu's behavior.

Zhang Chu said with a smile: "I'm going to open a hot pot restaurant."

"Hotpot restaurant?" Yin Li was startled.

Zhang Chu didn’t explain, just smiled and turned to leave.

Dai Qisi on the side looked solemn, and said to Yin Li: "A Li, senior has his own plan for doing this, you can't ask the bottom line like today."

Yin Li whispered: "I'm just curious. Why do you want to be a merchant if you are so tall, you can't be short of money?"

Dai Qisi shook her head and said: "The so-called great hermit lives in the city, the senior lives here day and night, and has no source of money, it will inevitably lead to suspicion..."

Hearing this, Yin Li suddenly realized, and quickly said: "I understand, so the young master is trying to deceive people."

"That's right, that's exactly the case. Senior is thoughtful, so we naturally wouldn't think about it." Dai Qisi smiled slightly.

…………

The recruitment notice hung up for two days, and passers-by knocked on the door to inquire or apply for the job.

But Zhang Chu is not satisfied with these people.

Business ability is secondary. Zhang Chu understands various business methods of later generations, and these ancient people are completely incomparable with him in this respect.

What Zhang Chu really values ​​is the character and mathematics ability of the applicant.

Needless to say character, cheating and cheating are naturally not acceptable.

And there must be a certain ability to calculate accounts.

This aspect is more cumbersome, and Zhang Chu doesn’t want to spend all his time on accounting.

Moreover, there are differences between the checkout and payment in ancient times and modern times.

In modern times, there is no need for the boss to pay the bill, and the customer can scan the QR code by himself.

However, in ancient times, the store needed to weigh the silver before cutting it, and the fire consumption of the broken silver had to be considered, so the operation was more complicated.

Just when Zhang Chu had a headache, there was a knock on the door outside the yard.

Opening the door, a fifteen or sixteen-year-old beggar appeared in front of Zhang Chu, holding the recruitment notice he had posted in his hand.

"Is there something wrong?" Zhang Chu was startled.

The little beggar raised the recruitment notice in his hand and said with a smile, "Aren't you recruiting shopkeepers here?"

Zhang Chu said with a strange expression: "You don't want to tell me that you are here to apply to be the shopkeeper?"

"Exactly." The little beggar replied with a crisp voice.

Zhang Chu couldn’t help laughing, and said, “little brother, stop making trouble, can you read?”

The little beggar asked back: "If you can't read, how do you know that you are recruiting the shopkeeper?"

Zhang Chu choked suddenly. The little beggar was really clever.

However, Zhang Chu still didn’t think that this little beggar could be a treasurer.

He casually asked a difficult question: "Okay, let me test you, what is 350 two plus 540 three?"

Originally, Zhang Chu thought that this question would be difficult for the opponent.

After all, in the ancient world, even scholars read the Four Books and Five Classics, and few people would study arithmetic.

Let alone a little beggar, I guess he has never read a book seriously.

As a result, right after Zhang Chu asked the question, the little beggar opposite immediately replied without thinking: "It's equal to 890 five."

Zhang Chu was taken aback immediately, and then looked at the little beggar again.

He didn't expect that this little beggar really knew mathematics.

Zhang Chulue pondered for a while, and asked a few more questions, most of which were elementary school mathematics questions, and occasionally there were individual questions that required junior high school mathematics level to answer.

But Zhang Chu didn’t expect that the little beggar on the opposite side answered all of them correctly.

Seeing that Zhang Chu was about to ask another question, the little beggar smiled and said, "I am familiar with "Nine Chapters of Arithmetic" and "Zhoubi Suanjing", so you don't need to ask these simple questions."

"..."

Zhang Chu felt despised.

I am also a college student anyway, how can I admit defeat in front of a little beggar?

He decided to give the little beggar a good education.

"I will ask one more question at the end. If you answer it correctly, I will let you be the shopkeeper." Zhang Chu smiled.

"One word from a gentleman, four horses are hard to follow." A smile appeared on the dirty face of the little beggar, as if full of certainty of victory.

Zhang Chu smiled, then cleared his throat, and said: "A and B take turns to report the number. Each person reports at least 1 number at a time, and at most 4 numbers. Starting from 1, whoever reports to 44 first wins. It’s A who reports the number first, is there a winning strategy?”

The little beggar froze for a moment, and said, "Shouldn't it be enough to just report to 44?"

Zhang Chu said with a smile: "I have said the topic, it must be reported in turn, and one cannot be missed."

The little beggar frowned and fell into hard thinking. After a while, he squatted down, picked up a branch, and began to write and draw on the ground.

Zhang Chu almost didn’t laugh out loud.

His problem was a primary school Olympiad problem in his previous life.
