Siheyuan: Returning from studying abroad, with extraordinary understanding

It can be said that this penicillin production process is a penicillin production instruction manual. As long as you follow the above steps, you can produce penicillin.

However, experimental verification is needed.

Lin Changqing doesn't think that he is omnipotent and that any plan he comes up with will definitely succeed.

Of course, the production of penicillin is divided into laboratory production and industrial production. After considering it, Lin Changqing engraved all the production processes.

Laboratory preparation is relatively simple, but industrial production requires specific equipment, and he doesn't know whether such equipment is available in the country.

This is not what he needs to consider. He has already lowered the production standards to the lowest level. If he still cannot produce it, he can only purchase equipment.

After Lin Changqing finished engraving, he looked at the time and found that it was past one in the morning.

After leaving the small world, he found that his sister had not woken up. He meditated for a while and then fell asleep.

The next morning, he woke up naturally because his biological clock kept steady.

He didn't feel tired at all. Visualization and martial arts training had greatly improved his physical fitness. Staying up late had no effect on him at all.

He got up quietly. Not wanting to disturb his sister, he took out yesterday's documents and put them in his bag before sitting down on the edge of the bed.

After taking a look at his sister and finding that she was still sleeping soundly, Lin Changqing did not disturb her and walked out of the room quietly.

Having practiced martial arts, his movements were light and graceful, and the sound made during the whole process was very small.

After washing up, Lin Changqing returned to the kitchen again and wanted to help but was driven out by his mother.

However, he still stayed in the kitchen and finally persuaded his mother to stay and help with the fire.

Watching his mother busying around and helping to light the fire, Lin Changqing suddenly felt like he was back in his childhood.

It was the same then.

Lin Changqing began to talk to his mother about his childhood, and time passed by unknowingly.

"Almost done, go wake Tingting up for breakfast."

"it is good."

Lin Changqing came to his room and found that his sister's sleeping position had changed. It was almost the same as what he saw last night, lying in the shape of a "big" character.

He came to the bed, pinched Lin Wanting's face, and whispered:

"Sister, wake up!"

"Ok?"

Lin Wanting responded unconsciously, then turned over, obviously not awake.

Lin Changqing had no choice but to increase his volume:

"Sister, sister, mother made something delicious. If you don't get up, I will eat it all!"

"There's delicious food there! I want to eat it!"

When she heard about the delicious food, Lin Wanting opened her eyes instantly and sat up immediately.

Just as he was about to get out of bed, Lin Changqing stopped him.

"Don't be so anxious, big brother won't snatch it from you."

Lin Changqing helped Lin Wanting tidy up her clothes before letting her get out of bed.

After coming out, I saw that my father Lin Fuxing had also gotten up.

After washing up, the family sat together and happily ate breakfast.

After breakfast, Lin Changqing took his sister out to digest the food.

It was only 7:30 in the morning. As soon as I arrived at the door, I saw a group of people coming in and out, some in a hurry, some leisurely. Obviously, everyone was busy and preparing to go to work.

Lin Changqing had a smile on his face the whole time, perhaps because he had promised to host a banquet yesterday. When these people saw Lin Changqing, they all greeted him with a smile.

Lin Changqing didn't say anything, just responded indifferently. He walked out and came to the front yard. As luck would have it, he saw Yan Bugui who was about to go to work.

"Changqing, good morning! Have you eaten?"

"Good morning, Teacher Yan. I've already eaten. How about you? I brought my sister out to help digest the food."

Lin Changqing smiled and pulled Lin Wanting.

Lin Wanting also said, "Hello, Teacher Yan."

"I've eaten too and am about to go to work." Seeing Lin Changqing's kind attitude, Yan Bugui also responded with a smile.

"Teacher Yan has to go to work! I won't disturb you anymore!"

"Sister, let's go for a walk."

After saying that, he wanted to pull Lin Wanting away.

As if nothing had happened, he didn't mention the banquet at all.

"Hey! Changqing, wait."

Lin Changqing paused after taking two steps, turned around and looked at Yan Bugui:

"Teacher Yan, is there anything else?"

"Yes, it's like this. Yesterday, after returning to the house, I made a list of what I needed for the banquet. Look, this banquet is hosted by your family, so I'm showing you the list."

Yan Bugui didn't receive Lin Changqing's money, and he always felt uneasy. He originally wanted to go find Lin Changqing, but he didn't expect Lin Changqing to come out.

When you see someone, you naturally have to catch him and ask him questions.

"I won't look at the list. Don't you believe me, Mr. Yan?"

Lin Changqing looked as if he could trust the person to do the job, which made Yan Bugui feel a little guilty.

But it disappeared quickly!

Guilt is nothing, he was even more heartbroken because he hadn't calculated it.

Therefore, Yan Bugui not only did not give up the idea of ​​cheating Lin Changqing out of twenty dollars, but became even more determined.

Who made you stupid!

"That won't do. You are the master, you can't not look at the list."

Yan Bugui did not feel guilty, but he still had to put on a show of pretending to be a master, otherwise he would be unjustified.

"Teacher Yan, you don't need to look. It's getting late. Don't you want to go to work? Otherwise, you will be late."

Lin Changqing reminded him kindly, but the more he did so, the more Yan Bugui wanted Lin Changqing to watch.

"It's okay to be a little late. The banquet is more important!"

Compared to being scolded for being late, cheating Lin Changqing out of 20 yuan would be more profitable, so he naturally didn't want to miss it.

"I'll leave the banquet to you, don't ask me."

Seeing that Yan Bugui never mentioned the money, Lin Changqing wanted to laugh, but he held it back.

"Teacher Yan, Lin Changqing, what are you talking about? It's getting late. Teacher Yan, aren't you afraid of being late?"

"Lin Changqing doesn't have to go to work, unlike you, Teacher Yan!"

Xu Damao came out and saw Lin Changqing and Yan Bugui, and couldn't help but stop to ask.

"We're talking about the banquet! Teacher Yan, I'll leave the banquet to you. If there's nothing else, I'll take my sister out to play."

Lin Changqing didn't want to get entangled with Yan Bugui anymore. If he said a few more words, he would probably burst out laughing.

Seeing that Lin Changqing was about to leave, Yan Bugui became anxious. He felt uneasy without getting the money.

So, I just went for it.

"Changqing! Look, the banquet list is out. Isn't it time for you to pay? Then I can arrange for someone to go shopping!"

Apparently he couldn't hold it back any longer, Lin Changqing suppressed his laughter and pretended not to understand:

"Teacher Yan, what did you say? Ask me to give you money?"

"No, Mr. Yan, when did I agree to pay?"

boom!

As soon as these words were spoken, no matter whether it was Yan Bugui, Xu Damao, or the passers-by.

When they heard that Lin Changqing didn’t give money, they were all stunned!

"Lin Changqing, didn't you agree yesterday? Do you still want to regret it? If you go back on your word like this, your family will never be able to live in our courtyard again."
