On the first day, they were all sold, and they made a net profit of more than 1,000 yuan, counting all kinds of other expenses, and buying the raw materials for the second day, Li Hang calculated that the profit was still quite considerable, and this was a pure profit, plus as long as it was a morning, the afternoon time could be used to do other things at home.

Li Hang carefully bought some alkali stone and got some plant ash, and he wanted to experiment and make some things.

Baking soda, baking soda, and caustic soda.

These are very easy to make.

Grass ash dissolved in water and then boiled is a trona solution, as long as it is filtered and crystallized, it is baking soda, and after filtration, a large amount of carbon dioxide is introduced and then close to baking soda.

If lime slurry is added to the trona solution, the two reactions can give a caustic soda solution and calcium carbonate. Commonly known as limestone.

In this way, as long as you can get enough caustic soda and baking soda, you can make a lot of things, such as a lot of soap, or make more delicious food.

This is the most important thing for Li Hang.

Making money is the first priority, and the ghost of the house needs to be well cared for, at least like a new home.

With the newly earned money, Li Hang bought a fish and bought some green onions, ginger and garlic, and ate steamed fish tonight!

Steamed fish with green onions, ginger and garlic to remove the fish, and finally drizzled with hot oil, the taste is ......

Carrying his things home, he spent the afternoon cooking a pot of trona in a separate jar in the back kitchen, and then began his preparation process.

The cheeks were about to blow out, and it took this large pile of baking soda to come out, plus those caustic soda crystals, and Li Hang also put the limestone aside.

That's what he did in an afternoon.

The next thing is to put these things in your own jar, and then put them away, and put all those things out of the reach of your sister-in-law, which is the real thing to watch out of.

In the evening, in order to celebrate, Li Hang personally cooked, steamed a big fish, and then copied a fish roe.

"Isn't it delicious?" While eating, Li Hang looked at his eight-year-old sister-in-law and asked with a smile.

And his wife Zhou Yurong was smiling reservedly on the side and eating reservedly, but the speed was not slow at all.

"Good times!" The sister-in-law said excitedly, she is a child, and she has no resistance to this kind of food.

Garlic leaves and stir-fried fish roe, the fragrance can literally waft out for ten miles, Li Hang also found a problem, that is, ancient fish are not as heavy as farmed fish, and they are relatively more delicious.

That's why Li Hang wants to do this kind of thing.

Chemicals are an essential part of what you eat.

At least baking soda is needed for a lot of pasta, and with this fried stall of your own, you can change out a lot of new tricks.

At night, Li Hang hugged his daughter-in-law, and he made a lot of money today, as long as he maintained this momentum, let alone what copper coins he had, he could earn silver.

The next day, Li Hang took these finished cakes and continued his own business.

This time he made a hundred cakes and asked the carpenter next door to make a mold that could cut them into standard 10-centimeter squares. In this way, it can be divided into nine, and it is easier to sell a little.

But this time, as soon as he played a song, Li Hang saw a vendor selling steamed cakes blocking his original stall.

As soon as he was about to find another stall, this guy came over with his little cart.

"Huh?" Li Hang gave him a strange look.

"Li Xiucai, you are powerful, but you didn't pay the money!"

"Paying the money? What do you pay? Li Hang frowned, there is nothing to say about the city management at this time, these small merchants and hawkers are basically in a state of no one to manage, and if they want to enter the city to buy and sell, they have to pay the head money, but what kind of place is this Donglin Port, a small place can no longer be small, what else can be taxed in this place, so there is no poll tax in this kind of place, pay money? To whom?

Li Hang was still thinking about this, when he saw that the peddler had taken two steps back after finishing speaking.

Behind him, a few sturdy guys were walking towards him, and the appearance of the dragon and tiger was a little embarrassing to see Li Hang.

Who is this? Some little gangsters?

At this time, Li Hang could be considered to react. Nima! Underworld!

From ancient times to the present day, this profession has never disappeared.

Li Hang looked at this strong man at the head, and he knew that he would never surpass this in terms of force value, so no matter what, it was impossible for him to clash head-on with this guy at this time.

"Li Xiucai, doing business here has to abide by the rules here, five hundred dollars a day!" The strong man walked over, his eyes full of disdain.

Five hundred wen a day, why didn't Nima grab it?

These people see that their business is good, so they want to ask for a sky-high price, it is obvious that these small traders on the side will be their little accomplices, this gang of people probably also see that their business is good, and it is estimated that their own business will also steal their business, so they also cooperate with this gang of gangsters.

"Your Excellency?"

"Sour! Sour Xiucai, Lao Tzu is the king of Matou Mountain! Who doesn't call me Brother Li here, everyone here pays me money, if you don't want to, this place is not allowed for you to practice stalls! Wang Dali said with his hands on his chest, and the tendon flesh on his body looked quite impressive.

"Five hundred wen a day, okay!" Li Hang agreed, and then retreated to the side.

At this time, Wang Dali didn't expect that this guy would give money so simply.

After thinking about it, this domineering leader on the dock looked at Li Hang with a cold face. "A thousand texts!"

"A man speaks with a word, and saying 500 is 500!"

"I'm up to the cracks here!"

Wang Dali sneered and walked over holding his chest.

Do you have to make inches? Li Hang shook his head. "I won't give it!"

At this time, Wang Dali clenched his fists with both hands and crackled, in his eyes, scholars were just scholars, as long as they showed their fists, they would give in. When the time comes, you can let him give the business to himself, and then sell it himself, hehe, give him a hundred Wen, that is worthy of him!

"Looks like I can't do this business!" Li Hang sneered, these people seemed to think that they had settled on themselves.

Wang Dali sneered. "In this Donglin port, all coolies have to listen to me, do you want me to go to your house! I want to beat you up in front of your mother-in-law, and she will give me this business, a scholar, beat you up in front of your mother-in-law, and you will have a better life in the future! What do you think? ”

"You can beat me up!" Li Hang's face turned cold.

From ancient times to the present, these pranksters are not good characters, and it is not a good thing to be entangled by them.
