She is no longer the wild girl she used to be, and everything she should do is based on the face of the Su family, instead of caring about a cloth workshop.

Su Zhiyu was very helpless when he saw this, so he returned to Du Ruonan's room without explanation.

In the next few days, things began to go smoothly in Ruoyulou, everything was on track, and the two had a chance to rest. Originally, Du Ruonan was going to settle the matter and return to the Prime Minister's Mansion.

But after dyeing cloth for the past few days, she suddenly had some new ideas.

You must know that this kind of temporary thought is quite important to them, and after some hesitation, Du Ruonan sent a companion to tell Su Zhiyu that she suddenly had some ideas and might go back a few days later.

Su Zhiyu is also quite familiar with fabrics, so he can naturally understand Du Ruonan, and the only thing he is embarrassed about is to tell Yurou about this matter. After receiving the news, he not only did not urge Du Ruonan to return home.

Instead, they also came to Ruoyu Building to help.

"Zhiyu, don't you have something to do today? Why did you come here again? ”

Du Ruonan said cautiously.

"My father temporarily told me that those things changed the time, so I am idle today, so I will simply come here to accompany you, and besides, I am already interested in fabrics than those things."

Su Zhiyu said with a smile.

He always thought that if he was not the only son of the Su family, then he would definitely run this cloth workshop with Du Ruonan, and for him, he preferred to study fabrics.

Because what he learned in the original world made him very comfortable with fabrics.

Du Ruonan told the two of them her thoughts, and it turned out that she felt that the color of the original fabric still needed to be improved, and it would definitely be brighter. After listening to her idea, the two also felt that it was feasible.

The three of them are all doers, and they do what they say.

The three of them each dyed cloth in front of a dye vat, of course, the three of them did different things, the temperature in their dye vat, and the ratio of raw materials, these are all different.

They need to figure it out little by little.

Soon the three of them dyed the fabric, but they were much disappointed.

The color of the fabric dyed by Su Zhiyu is not as good as the fabric sold by Ruoyulou at present, but the toughness is much better than the original, this can be sold to farmers, they don't need how bright the color of the clothes is, but the clothes are strong and the most important thing is for them.

The color of the fabric dyed by Su Mingyue is more beautiful than before, but it has lost its toughness, and it will break when the fabric is torn.

The fabric dyed by Du Ruonan was even more unexpected, and in the end, the fabric was dyed blue and purple, and the raw materials were not uniform at a glance, which indicated that the temperature of the cloth she dyed was wrong, or there was a problem with the matching of raw materials.

The first practice of the three obviously failed, although it was inevitable to encounter such a thing, but it still hit the self-confidence of the three people, after all, the three of them were full of experience in this area, but they still failed.

"Ugh."

Seeing the tragic situation of the three of them, Su Zhiyu couldn't help but sigh.

"You're too proud, aren't you, you've only failed once and you've been disgraced, isn't it possible that you have succeeded once in the past?"

Du Ruonan teased when he saw Su Zhiyu's disappointed face.

Su Zhiyu shook his shoulders helplessly and didn't say anything.

Du Ruonan and Su Mingyue didn't dye the cloth well, and they were just disappointed by this one thing, but Su Zhiyu was different, because he wanted to help Du Ruonan solve this problem.

But now he has failed, and he used to be a top student in chemistry.

Du Ruonan was not in a hurry to start dyeing the cloth for the second time, it was just a waste of resources, what she had to do now was to record the raw material ratio and temperature of the three people, and then analyze how to make the color of the fabric better than before.

"Mingyue, the fabric you dyed has lost its toughness, I think the water temperature is not well controlled, so the fabric will break as soon as it is torn, but the color is slightly improved compared to the previous one, and the fabric of Yu dyed is better than the previous toughness, but the color of the cloth is not very good, indicating that there are some problems with the ratio of raw materials, as for mine, the color and feel are not desirable."

Du Ruonan analyzed the failure products made by the three of them for the first time.

"But at least I've ruled out one of these situations as unreasonable, so let's move on."

Originally, Su Zhiyu thought that Du Ruonan was sad and wanted to come over to comfort her, but Du Ruonan cleaned up the old mountains and rivers and prepared to overcome this difficulty again.

In the next half month, in addition to eating and sleeping, the three of them basically spent all their time with the dye vat. They learn from the previous lessons, and then analyze the advantages of each other's fabrics, and start the next attempt.

Du Ruonan wrote a lot of things densely on the crumpled paper in his hand, although the paper was broken, but the things recorded in it were precious, enough to make many cloth shop owners rush to it.

Since several people must have been in contact with the dye to dye the cloth, this piece of paper is not only crumpled, but also colorful on it.

"Bang."

There was a loud noise, and when Su Zhiyu heard that it was Du Ruonan from here, he immediately turned around and looked at her.

It turned out that Du Ruonan's dye vat was blown up, but why the dye vat was blown up still needs to be further investigated by the three of them.

"Ruonan is fine."

Su Zhiyu and Su Mingyue asked with concern.

Du Ruonan smiled and shook his head, indicating that he had nothing to do. However, she looked very embarrassed, and the water in the dye vat splashed on her due to the explosion of the dye vat. 8090 Chinese

She now looks like a big cat.

"What does it smell like?"

Du Ruonan asked with a frown.

Su Mingyue sniffed and smelled a mushy smell.

"Ahh

Su Mingyue screamed and ran to her dye vat, and found that the fabric she had dyed was already paste, and she picked it up with a wooden stick like a puddle of mud. This is also the reason why people cannot leave when dyeing cloth.

In such a short period of time, the fabric was pasted.

And Su Zhiyu's accident is really already confused. But he didn't care very much, what he was most concerned about was Du Ruonan's safety, as long as Du Ruonan was safe, nothing else was a big problem.

Needless to say, the trio's attempt failed again this time. Although they inevitably had some disappointments, no one was discouraged, and they believed that they would succeed.

"It's getting late, so let's get here today."

Su Zhiyu saw that the sky was dark, and said to the two.

Du Ruonan saw that the hour was not early, although she was unwilling, but this kind of thing was in a hurry, and she still understood the truth that if you want to hurry, you can't reach it.

"Ruonan will leave this kind of thing to me in the future, if I don't leave it to the guys, you still don't want to do it yourself."

Su Zhiyu said with palpitations.

This time she was lucky, she didn't blow up or burn Du Ruonan, but no one can guarantee that she can be so lucky every time, so Su Zhiyu is still very worried in her heart.

"Don't worry, I'll be careful, besides, you're very experienced in this dyeing cloth, just say that you don't practice fake tricks, if you don't practice it yourself, how can you know if it's suitable or not."

The meaning of Du Ruonan's words is naturally that she must still dye cloth.

Su Zhiyu persuaded for a long time, but was finally persuaded by Du Ruonan.

After the dye vat was blown up, Su Mingyue asked the guys to clean up the place, and the three of them had a rare rest for half a day. The next day, they put their energies into dyeing cloth.

However, this time Su Zhiyu was very careful, of course, not very careful about the cloth she dyed, but kept paying attention to Du Ruonan's situation, for fear that she would be in danger again.

"It worked."

Du Ruonan took the dried fabric to the two of them and said excitedly.

"This fabric is really good, the feel and color are the best choice, it seems that you have made some things out this time."

Su Zhiyu touched the fabric that Du Ruonan brought, and commented very truthfully.

The three of them are very familiar with fabrics, so there is no need for him to fool Du Ruonan by saying nice things.

"Now that it's decided, let's try it again and see if there are any other problems, if not, we can make and sell it in large quantities."

Du Ruonan said to the two.

Although she had just taken the fabric back to show that she had succeeded, they had to do it again to make sure nothing went wrong, in case the cloth was accidentally successful by a blind cat and a dead mouse, and then they would find out that it was not feasible for the guys to start making it in large quantities.

At that time, a lot of raw materials will be lost, and it will also cause a waste of manpower, Du Ruonan doesn't want this to happen.

"It's exactly the same as last time? Why did it fail? ”

Du Ruonan looked at the fabric dyed by the three of them, and said with a frown.

There was no doubt that the cloth dyed by the trio according to her previous usage and usage did not work very well. And it takes her a lot of time to dye the fabric again and again.

Although Su Zhiyu didn't urge her to go back, she was still very anxious in her heart, she didn't go back for so many days, I was afraid that Yurou would be angry again.

Thinking of this, Du Ruonan couldn't help but be a little anxious.

"Ruonan, don't worry, think about it and see if you missed any important steps."

Su Zhiyu comforted Du Ruonan on the side.

Du Ruonan carefully recalled the only time he succeeded, and felt that he had recorded all the steps, and there should be no omissions.

"Could it be because of this?"

Du Ruonan muttered to himself, as if he had thought of something.

"Do you know why?"

As soon as the two heard Du Ruonan say this, they immediately leaned over and asked.

It turned out that the last time Du Ruonan was dyeing fabrics, she soaked the raw materials in water for one night, and she didn't think it was an important thing, so she didn't care.

Now that I think about it, it seems that this was the key to her last success.
