Professor Wang felt terrible.
However, what Lu Yu said next made him feel a little better.
"This kind of technique of making color paste usually requires people to practice it for years to learn. It's definitely impossible to learn it quickly in a short period of time.”
"However, if you want to study it, I can make a batch of color paste for you for free.”
"Blue dye is a good technique, and it has been an intangible cultural treasure of our Yanxia Empire for thousands of years. I don't wish for it to decline just like that.”
"With the current advanced technology, the finished product of the colored cream should be able to be analyzed using various instruments, right?
In this way, he might be able to analyze the dosage that the ancients could only grasp based on experience.”
Lu Yu spoke very sincerely and did not have the slightest intention of putting on a show.
Professor Wang felt a lump in his throat when he heard Lu Yu's words.
This young man was really a very good person!
He clearly had a traditional skill that only he could master, but he was not arrogant or impatient. He did not show off, but was willing to teach this skill to others without holding back.
Professor Wang was so excited that his lips were trembling. For a moment, he couldn't think of anything to thank Lu Yu.
A moment later, he typed a line of words on the keyboard:
" Aizen in My Heart: Streamer Lu Yu, thank you so much for supporting us in restoring Aizen's technology!
Blue Dye Heart: " I don't think it's a good idea to give away the color cream for free. I'm willing to pay 50,000 yuan to buy one from you."
'Although it's not much, it's just a little token of my appreciation.'
[Blue Dye Heart: If you can achieve a breakthrough in your research, I will represent the Jiangnan Weaving and Dyeing Association and apply for a reward for you!]
Lu Yu was a little surprised by Professor Wang's words.
He really didn't want to ask Professor Wang for the money, and he didn't need it.
However, since Professor Wang had already said so, it would be hypocritical to refuse again. Therefore, Lu Yu did not stand on ceremony and nodded.
"In that case, I'll make a few more red and yellow color creams for your reference.”
Professor Wang did not expect Lu Yu to give him an extra gift. He was so excited that his old face was smiling like an old chrysanthemum.
Good, good, this is great!
If he had a sample to analyze, he might really be able to make some breakthrough progress!
On the other side, after Lu Yu finished speaking, he did not have the intention to chat anymore. Instead, he sat down and continued to make the color paste.
After carefully cleaning the stone mortar with water and making sure that there was no indigo residue inside, Lu Yu began to make the yellow and red paste.
Other than the difference in the initial steps and the final proportion of the mixture, there was nothing else worth noting.
Because the amount of yellow and red paste was less, the production speed was also faster.
Even so, by the time the three color creams were finished, the sky had already completely darkened.
Taking off his gloves, Lu Yu stretched his body slightly and looked at Lee Zhengxiao.
"Let's eat first. We'll do the rest of the work after eating.”
"I'm fine with anything. Brother Lu has the final say."
Lee Zhengxiao had just eaten two oranges when he was idle, so he wasn't very hungry now.
Walking to the stone table, Lu Yu was about to pick a few bean products that Lee Zhengxiao brought back from the tofu shop in the afternoon to stir-fry when someone knocked on the door.
Hmm?
Lu Yu looked up and saw Aunt Yang Jin standing at the door with a box-like object.
Seeing Lu Yu raise his head to look at her, Aunt Yang Jin smiled and carried the box into the courtyard.
She placed the box on the stone table and said,"
"Xiao Rou came back and told me that the two of you were making blue dye and were very busy at the moment, so she specially made a meal and asked me to send it over so that the two of you wouldn't have to cook alone.”
As she spoke, Aunt Yang Jin opened the food box and took out the vegetables inside.
Lu Yu and Lee Zhengxiao stuck their heads out to take a look. Wow, good heavens, it's quite sumptuous!
Two meat dishes, two vegetables, and a soup.
This was the standard four dishes and one soup!
Liu Yuerou hadn't been back for long, but she had already cooked so many dishes. It seemed like she was quite good at cooking.
"Speaking of which, Xiao Yu, what did Xiao Rou say when she came over? Why is this girl so embarrassed to send the food over after cooking? Why must she push me to send the food over?”
Aunt Yang Jin was already so old. Of course, she could guess what these young people were talking about. However, for the sake of her daughter, she still wanted to sound out Lu Yu.
"I didn't say anything. I was just joking. Xiao Rou is shy, so I'm embarrassed.”
Lu Yu smiled.
Hearing Lu Yu's words, Aunt Yang Jin felt a little regretful, but she did not express it on her face.
The two children still had a lot of time to spend together. There was no hurry.
"Alright, I'll leave the food here for you guys first. The two of you hurry up and eat while it's hot. Don't starve yourself while you're busy working.”
Aunt Yang Jin waved her hand and left Lu Yu's house.
Seeing that Aunt Yang Jin had left, Lu Yu and Lu Li sat down and started eating.
After tasting a little of each dish, Lee Zhengxiao was a little surprised.
"Sister Xiaorou's cooking is not bad. Although it's still a little bit worse than Brother Lu's, it's much better than the average person.”
After saying that, Lee Zhengxiao winked at Lu Yu slyly.
"Brother Lu, are you really not going to consider Sister Xiaorou? She was beautiful, kind, and good at cooking. Where could he find such a girl?”
"You said that. You can't just say it like that. Feelings have to be cultivated.”
Lu Yu glared at Lee Zhengxiao.
"If the female colleague you get along with every day confesses to you that she likes you, wouldn't you have to think about it? Besides, Xiao Rou didn't express that intention.”
"Besides, I just came back and have a lot of things to do. How can I have time to date now? Do you want me to accompany you to climb mountains and ridges every day and carry a hoe to the fields?”
"That seems to be the case."
Lee Zhengxiao scratched his head and said after thinking for a while.
On the other side, Liu Yuerou, who was hiding in her room and watching the livestream, stomped her feet in anger when she heard Lu Yu's words.
Did he really not understand or was he pretending not to understand?
Did he really have to take the initiative?
Her friends always told her that if a girl was too proactive, the boy would not cherish her.
But, but if she did not take the initiative, what if someone else took the initiative first?
After all, her Brother Yu was so outstanding!
While Liu Yuerou's imagination was running wild, Shen Qingmei stomped her feet in anger.
Seriously…he actually forgot about Liu Yuerou's existence!
When he first met Liu Yuerou, she was still a little girl. Her body was covered in dust and her face was covered in dirt. Her skin was also tanned.
Now, she had actually grown up to be so beautiful…
It seemed like a huge threat.
Shen Qingmei gently bit her lips.
However, Lu Yu's words reminded Shen Qingmei.
Lu Yu's live broadcast room had just started, and his popularity was still rising rapidly.
There were still many things that needed to be dealt with at home.
There were still many things to do.
If she continued to pester him at this time, it was very likely that it would have the opposite effect.
A truly sensible woman should understand the other party's needs.
If he blindly clung to the other party, he might end up being annoying.
Thinking of this, Shen Qingmei was relieved.
Although she couldn't be by Lu Yu's side and see him all the time like Liu Yuerou, she could still help Lu Yu in many other ways with the many resources she had in the Imperial Capital.
Naturally, Lu Yu didn't know what Shen Qingmei and Liu Yuerou were thinking about. He hurriedly finished his meal, washed the dishes and chopsticks, and put them back into the lunch box. He asked Li Zhengxiao to run an errand for him to send them back to Aunt Yang Jin's house. Then, Lu Yu continued to work.
Lu Yu had already placed the three color creams that he had prepared into a small porcelain jar. They were placed neatly in a row, looking a little cute.
Lu Yu mentioned the bucket of soybean milk that Lee Zhengxiao had brought back.
There was already a thin layer of oil on the soybean milk. This layer could not be used.
He carefully removed the oil skin and poured it into a large pot. He placed it over the fire and boiled it.
Lu Yu turned around and returned to his room, bringing over the cotton cloth that he had made earlier.
Then, under everyone's watchful eyes, he threw the cotton cloth into the soybean milk pot.
Everyone in the live broadcast room was confused. Countless comments flew across the bullet screen.？？”
What was Brother Lu doing? Dyeing cloth? Why did they use soy milk to dye cloth? Shouldn't he use colored water?？
I was stunned. For a moment, I didn't know whether I should feel sorry for the cloth or the soybean milk…
He felt that the texture and taste of the cotton cloth would be quite good after the soy milk was boiled…
Looking at how everyone was enthusiastically discussing how to eat the cotton cloth that had been boiled with soybean milk, Lu Yu couldn't help but burst out laughing.
"The cotton cloth can be eaten, but it can only be eaten once in a lifetime. If he was lucky, he might be able to eat it two or three times.”
Hearing Lu Yu's words, the live broadcast room burst into laughter again.
I just found out today that Brother Lu is quite good at telling cold jokes.
After everyone finished laughing, Lu Yu continued,
"Using soybean milk to boil cotton cloth is actually a kind of ancient wisdom.”
"If we use modern techniques to analyze it, it means that after the cotton fiber is coated with protein, it can be colored more easily.”
"In this way, the cotton cloth that may need to be repeated seven or eight times to be perfectly colored only needs two or three times after boiling the soybean milk. It can greatly reduce the workload and working time.”
Lu Yu smiled." Actually, sometimes when I think about it, I also admire those ancient people."
How did the first person who came up with this idea find out that cotton cloth could be colored better when it came into contact with soybean milk? Could it be that he really wanted to use soy milk to cook cotton cloth to eat?”
While they were chatting, the kitchen timer that Lu Yu had placed at the side started to beep.
The cotton cloth was already cooked.
