Just as the three girls were thinking hard about solutions to the problem, a creativity emerged from Chen Zhe's head.

The cheongsam is too transparent, not just because the silk is too thin.

Of course, there is indeed one reason why silk is too thin, but there is another reason why this cheongsam is too transparent - that is, the silk itself is white.

White clothes are the most difficult to cover, especially when they are penetrated by strong light, the darker part of the clothes will be revealed immediately.

Xiao Qiao's embarrassment just now also has a certain relationship with the white color of the cheongsam itself.

So as long as the white cheongsam is dyed, this problem can be solved.

"I have a way..." Chen Zhe cleared his throat and said, "If we could dye these cheongsams, then these cheongsams would not be so transparent."

"Dan, dye?" Yan'er didn't think of this. After listening to Chen Zhe's words, she suddenly felt that her thoughts were opened by Chen Zhe.

Da Qiao nodded repeatedly and said, "This is a good idea. The white clothes do not block the light and look transparent. If the white cheongsam can be dyed with some darker colors, the cheongsam will definitely not be so transparent."

After listening to everyone's analysis, Xiao Qiao said nervously: "Dyeing... This sounds like a good idea. But is the plan to dye it on the island feasible? Chen Zhe, will you dye it?"

Chen Zhe smiled lightly and said, "It's just finding natural dyes to dye the clothes. This is the most technical thing I have done since I came to the island."

Da Qiao also smiled and said, "Yes, Chen Zhe can even make black gunpowder and dye his clothes with color. Do you think it's difficult to get him?"

"Uh...well, it seems that my worries are unnecessary." Xiao Qiao said with her tongue stuck out.

...

After confirming the solution, Chen Zhe began to take action.

If you want to dye silk, the first thing you need to look for is natural dyes.

Many plants in nature are rich in pigments and can be regarded as natural dyes. For example, the mulberries that Chen Zhe and others usually pick can be extracted after pressing them.

However, it is more valuable than using mulberries as food. Chen Zhe is certainly not stupid enough to make dyes with precious fruits. After all, getting food on the island is more important than dyeing clothes. He can only prioritize it.

Carrying a blood-drinking knife, Chen Zhe was strolling in the forest, and his eyes were looking around the flowers in the bushes.

Yan'er and the Qiao sisters also followed him. The three girls could find some brightly colored flowers from time to time, but these flowers were either too small to scale or were not easy to decolorize and could not become natural dyes.

If you want to find the right materials, you have to work hard.

Fortunately, the tropical islands are rich in plant resources, and flowers and colored plants are everywhere.

After walking a kilometer forward, Chen Zhe discovered some magical plants.

It was a pink, surrounded by small petals, which looked a bit like a colored dogtail grass. They grew in groups, densely spread across the grass.

When Chen Zhe saw these flowers, he smiled.

Regardless of whether these flowers can serve as suitable pigments, at least they are in sufficient quantity.

At this time, Yan'er and the others also discovered these magical flowers, and the three girls quickly chased after them.

"Chen Zhe, what kind of flower is this?"

"These flowers are so beautiful, pink and tender. Can we use them to make dyes?"

Chen Zhe nodded, then leaned over and picked a flower.

He didn't know what flower it was now, so he had to use the system to tell the girls.

Soon the system gave a prompt:

【Detected item: a high-quality polygonum vegetation.】

Seeing this, Chen Zhe suddenly realized and smiled and said, "Oh, the name of this kind of flower is Li Lan."

"Liang Lan?" Yan'er nodded and said, "It's a nice name."

Da Qiao asked, "Lipo-lani? Is it a kind of orchid?"

"No." Chen Zhe smiled and shook his head, "The blue of the lily blue is blue."

"Blue blue?" Da Qiao became puzzled, "But they are obviously pink flowers, why are they called 'blue'?"

Chen Zhe explained: "In fact, this kind of flower can extract a commonly used color for ancient drifting and dyeing - indigo, so it is called podocus. It actually has another name, which is called indigo."

After systematically distinguishing the types of Polygonum, Chen Zhe remembered its efficacy and origin.

In a film and television work in my last life, Chen Zhe came into contact with the role of the small boss of a dyeing workshop. Indigo is one of the very important colors, and the lye is just the raw material for refining indigo.

However, after hearing Chen Zhe's popular science, the girls became even more curious.

"Brother Chen, are you talking about these pink flowers that will get blue after being refined?" Yan'er asked with a pair of charming eyes.

Chen Zhe smiled and shook his head and said, "Of course not. Pink is always pink, no matter how it is refined, it is pink. The dye used to extract indigo blue is made through its stems and leaves.

We must first chop its stems and leaves and put them in the bucket, stir thoroughly, and wait until the stems and leaves rot and peel off, and then add lime to the bucket, so that we can extract the indigo dye we need."

"So that's how it is." Yan'er suddenly realized, "The indigo pigment does not come from the flowers of Polygonum, but from their stems and leaves."

"Yes." Chen Zhe nodded.

At this time, Xiao Qiao asked again: "But Chen Zhe, what else do you want to add to Lilan... lime? We don't have lime here."

Chen Zhe said: "It is okay to have no lime, volcanic ash. Don't forget that last time I brought back a lot of volcanic ash to make cement mortar."

"That's how..." Xiao Qiao's doubts were completely dispelled, and he nodded and said.

Da Qiao next to him looked at Chen Zhe with admiration and asked in surprise: "Chen Zhe, why do you know so much about making dyes? It seems that you have made dyes by yourself...

Like what kind of Polygonum, what parts of Polygonumum are used to make dyes, and also adding lime to the stems and leaves...

Without work experience in this area, it will be difficult for ordinary people to understand, right?”

Chen Zhe smiled softly. Of course he couldn't tell Da Qiao that it was because he played a small boss in a dyeing workshop in his last life, so he knew all this.

"Because I prefer reading some popular science books, one of which has been introduced in it." Chen Zhe said with a smile.

Da Qiao did not doubt Chen Zhe's statement and nodded in praise: "You are so knowledgeable..."
