Just as the three girls were struggling to figure out how to solve the problem, an idea popped up in Chen Zhe's head.

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

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

White clothing is the most difficult to cover, especially when exposed to strong light, which will immediately reveal the darker parts of the clothing.

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

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

"I have a way to ......," Chen Zhe cleared his throat and said, "If we can dye these cheongsams with color, then these cheongsams should not be so transparent." ”

"Dyeing, dyeing?" Yan'er didn't think of this, after listening to Chen Zhe's words, she suddenly felt that her thinking was opened by Chen Zhe.

Da Qiao also nodded again and again, and said: "This is a good idea, the white clothes themselves are not shading and transparent, if you can dye the white cheongsam with some darker colors, then the cheongsam will definitely not be so transparent." ”

After listening to everyone's analysis, Xiao Qiao said with some apprehension: "Dyeing...... That sounds like a good idea. But is it feasible to dye on the island? Chen Zhe, do you know how to dye it?"

Chen Zhe smiled lightly and said, "It's just to find natural dyes to dye clothes in color, this is the most untechnical thing I've done since I came to the island." ”

Da Qiao also smiled and said: "That's right, Chen Zhe can even refine black gunpowder and dye his clothes, do you think it will be difficult to get him?"

"Uh...... Well, it seems that my worries are unwarranted. Little Joe stuck out his tongue and said.

……

After determining the solution, Chen Zhe began to act.

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, which can be used as natural dyes, such as the mulberries that Chen Zhe usually picks, and after pressing, they can be refined to produce purple pigments.

However, mulberries are more valuable as food than as dyes, and Chen Zhe is certainly not stupid enough to use precious fruits to make dyes, after all, getting food on the island is more important than dyeing clothes, and he has to score clearly and prioritize.

Carrying a blood-drinking knife and wandering through the forest, Chen Zhe's eyes searched for the flowers in the bushes.

Yan'er and the Qiao sisters also followed him, and the three girls could find some brightly colored flowers from time to time, but these flowers were either too few in number to be large-scale, or they were not easy to decolor and could not become natural dyes.

Finding the right materials requires a lot of hard work.

Thankfully, tropical islands are rich in flora, with flowers and coloured plants everywhere.

After walking another kilometer, Chen Zhe found some magical plants.

It was a pink, clustered, small-petaled flower that looked a bit like dyed dog's tail grass, growing in groups and densely spread across a patch of grass.

When he saw these flowers, Chen Zhe smiled.

Whether or not these flowers can be used as suitable pigments, at least there are enough of them.

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

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

"These flowers are so beautiful, they are pink, we can make dye out of them, right?"

Chen Zhe nodded, then leaned over to pick a flower.

He doesn't know exactly what kind of flower it is, but he has to use the system to take a look at it before he can tell the girls.

Soon the system will give you a hint:

[Item detected: A high-quality indigo.] 】

Seeing this, Chen Zhe suddenly realized, and said with a smile: "Oh, the name of this flower is indigo." ”

"Indigo?" Yan'er nodded and said, "It's a nice name." ”

Da Qiao asked, "Is it a type of orchid?"

"Nope. Chen Zhe shook his head with a smile and said, "The blue of knotweed is the blue of blue." ”

"Blue blue?" said Da Qiao, confused, "but they are all pink flowers, so why are they called 'blue'?"

Chen Zhe explained: "In fact, this flower can be extracted from an ancient bleaching and dyeing color - indigo, so it is called indigo, and it actually has another name, which is called indigo." ”

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

In a film and television work in the last life, Chen Zhe came into contact with the role of a small owner of a dyeing workshop, indigo is one of the very important colors, and indigo happens to be the raw material for refining indigo.

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

"Brother Xiao Chen, are you saying that these pink flowers will get blue after refining?" asked Yan'er with a winkful pair of eyes.

Chen Zhe shook his head with a smile and said, "Of course not." Pink is always pink, and no matter how you refine it, it's still pink. The dye used to refine indigo from indigo is refined through its stems and leaves.

We first chop the stems and leaves and put them in a bucket, stir them well, wait until the stems and leaves rot and peel, and then add lime to the bucket to refine the indigo dye we need. ”

"I see. Yan'er suddenly realized, "The indigo pigment does not come from the flowers of indigo, but from their stems and leaves. ”

"Yes. Chen Zhe nodded.

At this time, Xiao Qiao asked again: "But Chen Zhe, what did you just say you want to add to the indigo...... We don't have lime here. ”

Chen Zhe said: "There is no lime, volcanic ash is also possible, don't forget that last time in order to make cement mortar, I brought back a lot of volcanic ash." ”

"That's ......" 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......?

Like what kind of indigo, what part of indigo is used to make dye, and add lime to the stems and leaves......

If you don't have experience in this area, it's hard for the average person to understand, right?"

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

"Because I prefer to read some popular science books, there is a book that introduces it. Chen Zhe said with a smile.

Da Qiao did not doubt Chen Zhe's statement, and nodded approvingly: "You are really knowledgeable......
