Whether in the East or the West, purple was a noble and expensive color in ancient times. The reason was that purple had few dyes and purple was not easy to color.

The purple dye in plant dyes is generally purplish, and the roots are dyed. Multiple purple colors with different shades can be dyed, with rich colors.

But the staining of purple grass has great disadvantages... Books flashed through Wang Kang's mind, and finally he determined the method.

In 1758, a London copper smith accidentally discovered a dyeing workshop using several lichen plants to make purple dyes.

The method discovered by the coppersmith is a method of making lichen dyes in ancient Greece. It is made of Mediterranean lichen and is refined with urine (ammonia).

What is lichen? It is actually a bryophyte, and the source of the purple dye is litmus lichen.

This kind of bryophyte is everywhere and is not worth anything at all, but the purple color that is purified from it is the best.

According to the method in the book, Wang Kang found lichens and added urine and other ingredients to make them, and soon proposed a pure purple color.

Next, alum was added to brighten, which is also a very critical step. The fabric silk of this era was rigid and even darker, and the big reason was that it did not undergo the brightening process.

Then Wang Kang found a piece of pure white and colorless silk and began to dye it. In his way, it was naturally evenly dyed.

The next step is very simple, just wait until it is dry. Fortunately, the sun is very high today, and purple silk appears soon.

Wang Kang compared the purple silk he dyed with the one he wore, and it was obvious that the purple silk clothes he wore were just a slag.

Under the reflection of the sun, the purple silk exudes a bright light, precipitated and deep, which is the noble purple.

At this moment, in the backyard of Fuyang Buzhuang, a room dedicated to rest, Lin Yuyan, Xu Changlin and Manager He were sitting opposite each other.

"Daichi Xu wasn't it. Master Kang is really a waste of money. He can't just say so much information..."! Manager He complained.

"It's very difficult for me to configure this once. There is still a batch of silk to dye it soon, which delays the construction period. Isn't the loss of our Fuyang cloth shop?"

"That's fine, he said arrogantly that he had a better dye formula? It's such a big joke." Manager He said disdainfully.

"Old He, you are also an old man from the Earl's Mansion. You can't pay attention to what the young master looks like. It's not our turn to say anything!" Deacon Xu said with a slight angrily.

"I'm blaming me for saying more?" Manager He snorted coldly, "If he can really make a better dye formula, I won't even call him Young Master, I can call him Grandpa!"

"Oh? Who wants to call me grandpa?" Wang Kang, who was walking into the door, asked when he heard this.

"This..." The gossip behind the scenes was heard, and Manager He was so embarrassed that he didn't know what to say.

"Young master is out. I've been waiting here for a while. There are still many things to deal with in the Earl's Mansion, so let's go back first!" Xu Changlin said hurriedly.

As for the dye formula, he didn't even mention it, just because he was afraid that Wang Kang would be embarrassed.

"I wonder if Young Master Kang can prepare a better dye formula?" At this moment, Manager He asked.

"Shopkeeper He...you?" Xu Changlin glared. He just didn't want to mention this matter so he led it elsewhere. You should not open the pot of the pot.

I am so blind and don’t know what happened to Manager He today, so I resisted Young Master Kang.

Wang Kang was also a little angry at this moment. Manager He spoke sarcastically and did not have the young master in his eyes. Combined with the previous incident, Wang Kang instinctively felt that there was something wrong with this guy.

Wang Kang looked at Manager He deeply and used his identity to interpret it. In an instant, the information of this person appeared in front of him.

He An, the shopkeeper of the Fuyang Buzhuang South Street Branch, has been bribed by Dong Gan... In an attempt to find a better dye formula for him and help the Liu family open a dyeing shop...

I really don’t know if I don’t look at it, I’ll jump when I see it!

Although Wang Kang's expression remained unchanged, his heart was already in a state of great turmoil. This shopkeeper He had been bribed by Dong Gan.

If he remembers correctly, Dong Gan is the eldest son of the governor Dong Yiwu, and the reason for the purchase was that the Liu family also wanted to open a fabric shop...

The amount of information here is a bit large. As the shopkeeper of the branch, He An not only knows a lot about the business of Fuyang cloth shop, but also knows the dye formula...

If this is leaked, it will be a big blow to the Earl's Mansion.

And more importantly, I wonder if there are still people like He An in the Earl's Mansion who have been bribed?

Wang Kang's eyes quickly turned around and he thought of a counterattack. It would be better to just use a trick!

"Why doesn't Young Master Kang speak?" He An asked again.

"I'm thinking about a question," Wang Kang said to He An Zhenzhong.

"What's the problem?" He An asked subconsciously without understanding.

"You just said that if I really made better purple dye, just call me grandpa. Does that count?" Wang Kang asked.

"Young Master Kang, you..." He An's expression stagnated, and then he said, "Of course I count."

You, a prodigal son, can you make a better formula? I don’t believe it if you beat him to death. He An was disdainful. He knew that he must have offended Wang Kang today.

But he was not afraid at all. As Wang Kang knew, he had been bribed by Dong Gan and went to the Liu family, and in the future he would become the shopkeeper of the Liu family's cloth shop.

"Okay!" Wang Kang nodded, "Deacon Xu, you heard it, you need to be a proof!"

"Young Master, this..." Deacon Xu looked difficult. I heard it, but the premise is that you have to take out something, but he can't say this.

"If you really made the recipe, I can call you grandpa, but what if you don't have one?" He An glanced at Wang Kang and said.

"Although Mr. Kang is the Count, you must be unreasonable!" He An said sarcastically: "If Mr. Kang can't come up with the recipe, I don't ask for anything else. As long as you, Mr. Kang, apologize to me!"

"Shopkeeper He!" Deacon Xu's voice was already cold and said: "What an identity is the young master? Please pay attention to your attitude!"

He An ignored him and still stared at Wang Kang.

"Wang Kang, let's go quickly..." Lin Yuyan also spoke at this time. This prodigal son is really not embarrassing enough. What can he do if he can do it?

If he really apologized to Manager He in the end, it would reduce his prestige, and the last thing he lost was Bo Fu Yang's face.

However, before she finished speaking, she was interrupted by Wang Kang. He looked at He An coldly and said, "Since you are so impatient to call me grandpa, then I will satisfy you!"

Wang Kang said, and took out the purple silk he dyed and placed it in the place where the sun shone through.

The purple silk was noble, grand, profound and lively, emitting a dazzling brilliance. As soon as they saw it, they were attracted to it and could not move their eyes away...

However, Wang Kang ignored the dull reactions of several people and said directly to He An: "How about Manager He? Are you going to call him grandpa?"
