For a modern person, it is easy to know that blue and red mix to form purple, but it was different in ancient times. Just for this point, you don't know how many times you have to experiment.

"Have you never tried using other methods to extract purple?" Wang Kang couldn't help but ask as he watched shopkeeper He carefully adjust the proportions.

Although this kind of mixture can produce purple, it is much worse when used to dye cloth. The most obvious thing is that the color reception is uneven and the proportion is difficult to adjust. If it is slightly wrong, the color may be different.

Moreover, the humidity of the two dyes is different, which causes the dyed purple cloth to fade easily.

"Of course I have thought about it. I once tried to use comfrey to extract the purple color, but the extraction process was too troublesome and extremely unstable. I couldn't find a suitable washing and rinsing time..." Shopkeeper He said subconsciously without raising his head.

"Hey, who is asking?" After he answered, he realized something was wrong. The voice was unfamiliar, and ordinary people were not allowed to enter this important dyeing workshop.

"Are you Master Kang?" After seeing Wang Kang's face clearly, Shopkeeper He stood up and exclaimed.

"Do you know me?" Wang Kang asked doubtfully. This was the first person in this cloth village to recognize him.

"Shopkeeper He has been with the earl for a long time, so he has naturally met you, young master." At this time, Xu Changlin came over and said with a smile.

"Deacon Xu!" Shopkeeper He greeted Xu Changlin. When he saw Lin Yuyan behind him, his eyes stayed for a while longer.

"I'm bringing the young master here for a visit today. You are busy with your work..." Deacon Xu ordered.

Then he said to Wang Kang: "Master, let's go elsewhere and take a look. There is a lot of miscellaneous smells in here, so don't choke you."

He was deeply afraid that Wang Kang would play tricks and affect the operation of the workshop.

"Just here." Wang Kang said impatiently, this guy was afraid that he would cause trouble.

He's here to deliver the formula.

"By the way, I wonder if Shopkeeper Hu has developed a better purple formula?" Shopkeeper He asked at this time.

"You are talking about Lao Hu," Xu Changlin said with a smile: "It is said that the number of rinsing times for comfrey to improve the color has been found. You should work harder."

"Ah, really? Then I have to study!" Shopkeeper He's eyes lit up and he said hurriedly.

"What to learn," Wang Kang said, "Dyeing with Lithospermum is too troublesome. It often needs to be bleached and dyed dozens of times before it can be dyed, and the color is not long-lasting after dyeing."

"I have a better method, do you want to learn it?" Wang Kang asked again.

"Master, do you know about Lithospermum? Do you also know the disadvantages of Lithospermum dyeing?" Shopkeeper He asked doubtfully.

He is an old man from the Earl's Mansion, he knows Wang Kang quite well, and he even knows what kind of person Wang Kang is.

This young master knows how to spend money and never cares about business matters. How could he know these things?

But listening to this voice, it seems that this is not the case. What this young master said seems to be very professional!

This surprised him very much.

Lin Yuyan also looked at Wang Kang in surprise. She made silk cloth at home, so she knew something about this.

They also participated in the experiment of purple dyeing formula, and the one they used was comfrey. After all, this is a common plant that can produce purple.

It's just that the extraction was not smooth, and the difficulties encountered were the same as what Wang Kang said.

"Is this weird? I just know it, and I also know a better formula?" Wang Kang said matter-of-factly.

"This is impossible!" Hearing this, Shopkeeper He's face changed. "I have been looking for the purple dyeing formula for a long time. I have tried countless materials and methods. If there is a better method, I will definitely find it."

"Shopkeeper He, this world is very big," Wang Kang looked up at him and said, "Besides, can you be sure that you have tried all the materials?"

"This..." Shopkeeper He was speechless. He was really not sure about this.

Seeing that Wang Kang and Shopkeeper He were fighting, Xu Changlin had a headache. He knew that this was the situation and that this man was going to cause trouble again.

Many craftsmen have not found a better formula, but you, a prodigal son who only knows how to spend money, still boast that there is a better formula. Isn't this a joke?

"Master, why don't I take you to the Jade Workshop? You will definitely be interested in the things there. If you like something, you can take it away!" Xu Changlin said hurriedly.

"Hey, you don't believe me, right?" Wang Kang said angrily.

None of them spoke, but the meaning in their eyes was clear.

"Okay, today Master Japan will open your eyes!" Wang Kang flicked his sleeves.

"Thanks to the fact that there are so many craftsmen trying to find it, this young master alone is enough!"

"Master Kang, you..." Shopkeeper He's face turned ugly, and even Xu Changlin looked extremely unnatural.

Wang Kang ignored them. He was always distrusted and he had long been impatient.

"You all go out, I am going to make a recipe!" Wang Kang said.

"Master Kang, please think about it again..."

Xu Changlin said with difficulty, what he was most worried about happened.

"I'm still brewing dye here. If I stop, it will all be wasted,"

"Besides, you, a young master who only knows how to gamble, don't know how to prepare dyes." Shopkeeper He said coldly.

"What did you say?" Wang Kang stared at Shopkeeper He.

"I only know how to spend money," Shopkeeper He added hurriedly.

"Get out!" Wang Kang pointed at the door. Seeing that no one moved, his voice also turned cold, "What? What I said doesn't work, does it?"

"But what material?" Shopkeeper He asked again.

"It's just that it's useless. Can't I, the Earl of Fuyang, afford it?" Wang Kang shouted coldly.

Waiting for him to prepare a better dye, what's the use of this?

Lin Yuyan looked at Wang Kang in disbelief. He finally saw the true face of this prodigal son. So many precious dyes were thrown away at the drop of a hat.

Moreover, she was so unreasonable that Lin Yuyan was so angry that she turned around and ran out.

"Let's go, Shopkeeper He, listen to the young master!" Xu Changlin sighed and pulled Shopkeeper He away. In the end, only Wang Kang was left in the room.

Wang Kang stared at Shopkeeper He's back with deep eyes. He heard clearly just now that Shopkeeper He said that he was a young master who only knew how to gamble.

gamble!

He recently gambled money at the Liu Family Gambling House. Although this incident was rumored at the time, the momentum has passed.

Moreover, after his commotion in Zuixianju, the Liu family also calmed down. Why did Shopkeeper He bring it up casually? Wang Kang instinctively sensed something was wrong.

It's a strange feeling.

I don’t think about it for now. Shopkeeper He will find out later. Now he needs to make the purple dye formula first.

He had just checked the books in his mind and already knew the formula of the dye.
