Things will not change with changes in people's ideologies. It does not mean that you can do whatever you want.

Any scientific invention and creation is achieved through summarizing experience after countless failures.

Quantitative changes will lead to qualitative changes. This is a very simple philosophical thought.

Failure is the mother of success, this saying explains this truth well.

However, if you deviate from the direction from the beginning, you will never succeed and will only go further and further away.

Just like Xiao Qi, if the convex lens is not successfully made, it will never be made into a microscope.

Zheng Changsheng actually wanted to tell her not to work in vain, but seeing Xiao Qi's obsessed look, he couldn't bear to break Xiao Qi's dream.

As long as people have dreams, even if they are unrealistic, they are better than living in confusion.

Quan should find something for Xiao Qi to do. It's better than having her idle Five Spine and Six Beasts coming over to harass him, right?

Regarding the preparation of penicillin, he only remembered a simple method, and he didn't know whether it could be done.

First, collect the culture solution of penicillin, use rapeseed oil to dissolve the lipophilic substances, filter it with activated carbon, and wash it with distilled water.

Use vinegar to make an acidic solution, and seaweed juice to make an alkaline solution. Wash and filter.

It's easy to say, but not so easy to do.

If anything is to be successful, it cannot be achieved overnight, especially the refining of a drug like penicillin. How can it be so easy to succeed?

Not all time-travelers have golden fingers, their tiger body shakes, their domineering energy leaks out, and everything can be done easily.

take it easy

The afternoon sun shone lazily on people's bodies, and Zheng Changsheng wandered around in the yard bored.

When we go to the big man's place, the snoring of this guy's nap can make the tiles on the roof shake off.

Xiaoqi was tinkering with her microscope. Although the shape was ready, wouldn't it be in vain if you didn't have a convex lens? But she was still experimenting. She tried countless times on the rice paper in the study and the film on the bamboo.

As long as she likes something, she will put it on the bamboo tube of the "microscope" to test it. Despite repeated attempts and failures, her indomitable spirit is really admirable.

As for my mother, she was hiding in her room counting money.

The huge kang hole was almost filled with money.

When she saw Zheng Changsheng coming in, she stopped counting the money and said, "Son, you see our money can't fit in the kang hole. Tell me, what should we do?"

I don’t know if she is showing off or if she is really worried about storing money.

"Mom, why not let the big man dig a silver vault? It will save you the trouble of hiding money every day."

"Well, my son has a great idea. Where's the big guy? Call him over quickly. We'll just do it."

Let me go, when will my mother's habit of listening to wind and raining rain change?

I just said it casually, but she took it seriously. Sorry, I'm sorry for you, big man. I'm afraid you are too tired.

The big man Zheng Keunshuo was woken up by his mother in his sleep.

I don’t know why this guy is so good-natured. When he heard that his mother asked him to dig a cellar to hide the money.

He just wiped a handful of saliva, picked up the pickaxe and started working without saying a word.

I couldn't sleep on my mother's kang, so I guess I would have to sleep with Xiaoqi at night.

The big man lifted up the wooden board and started digging.

"Well done, dig deeper so that our family's money can be hidden more tightly." Mother encouraged beside her.

Alas! Zheng Changsheng can't leave either. It's him who took care of this. He has to be there to give guidance.

The son is a child prodigy and the inheritor of the profound knowledge written by the ancestors of the Zheng family. Of course, what he said makes sense.

This must be done well under the guidance of my son.

This is Li Xiuying’s true inner thought.

On the afternoon of the next day, a five-foot-square hole was finally dug. The big man was panting and sweating from exhaustion: "Woman, do you think this is okay?"

"Son, do you think this is okay?"

Zheng Changsheng was speechless, "Okay, as long as I can let go of your treasure."

"Well, that's alright. Big man, come up and have a rest."

After completing his mother's plan to hide money, the big man was almost exhausted from exhaustion, and he was going crazy from boredom, but his mother was happy and happy.

Finally, she fished out a piece of silver from her sleeves for a long time and said, "Here, take it, big man, don't tell anyone what happened today. All our money is hidden here.

If people find out, it won’t be safe, you know?”

The big man held the broken piece of silver in his hand, giggled and nodded vigorously.

Zheng Changsheng knew that even if this matter got into the big man's belly, even if you beat him to death, he would not tell anyone about it.

Mother hid the money, restored the fire kang, and breathed a sigh of relief.

"Big man, you have to pick out the soil dug out of the house." This was my mother's new order.

Well, the big man found a bamboo basket, cleaned up all the soil and put it in it, ready to take it outside and dump it.

Zheng Changsheng picked up a piece of soil, looked at it, twisted it in his hand, and rubbed it. It was fine clay.

"Wait a minute, big man, this dirt can't be poured down."

"Well, Master, this is some ordinary soil. We have a lot of it here. If you want to play with mud, I will find you some soil that is finer than this. I will ensure that you have a great time playing."

Li Xiuying was a little dumbfounded when she saw the solemn expression on her son's face. Could it be that this child had imitated Lu Shenxian?

Isn't this just earth and mud? Could it be used as a magical elixir?

Zheng Changsheng slapped his thigh: "Big man, do you think we have finer soil here than this?"

The big man Zheng Genshuo was confused by Zheng Changsheng's question: "Well, Master, don't you know that this is the kind of soil we have here?

The fields and slopes are all filled with this kind of soil. How much do you want? As long as you tell me the number, it won’t be a problem for me to dig out a mountain for you.”

Clay is an excellent material for making porcelain and bricks. Now it is sitting on a mountain of gold, haha.

"Mom, we are going to get rich, we are going to get rich."

Li Xiuying was confused. She walked a few steps and came to Zheng Changsheng. She stretched out her hand and touched his little head, and then touched her own forehead.

"This kid talks nonsense and doesn't even have a fever. How can this dirtbag make a fortune? Don't bully my mother because she doesn't read as much as you do. She still understands this."

"No, you don't understand. This soil is an excellent material for making porcelain and bricks."

"What? You said that the porcelain pots and bowls in our house and the bricks and tiles used to build the house were made from this kind of soil?"
Chapter completed!
