Shen Lang couldn't help but look at Tian Shisan again, because he represented the will of Tian Heng of the black-clothed gang.

When Shen Lang was making dyes just now, Jinxiu Ge Lin Mo betrayed him and sent someone to notify the Xu family to come. Tian Shisan obviously saw it, but he didn't mean to stop him, and he didn't remind Shen Lang. .

Therefore, at this time, Shen Lang was facing three behemoths.

The Xu family, the Lin family, and Tian Heng in black.

So now his smartest way is to admit that this formula is stolen, and then immediately go to implement the great cause of upgrading the soft rice, and then take revenge crazily when he has power and power.

Because Xu Qianqian agreed in front of the officials of Xuanwu City, if Shen Lang pleads guilty, everything will be forgotten.

She is a person who cherishes her reputation. If Shen Lang pleads guilty, she will definitely not attack him in person today, and will only pay Tian Heng to deal with him secretly, so that at least Shen Lang will be safe today.

But!

Want to throw this pot of dirty feces on Shen Lang's head, and let him dry himself?

Absolutely can't do it, Shen Lang will never be so useless.

Shen Lang looked at Xu Qianqian and asked, "You said that my new formula for golden yellow dye was stolen, what evidence is there?"

The head of the Xu family sneered: "You Shen Lang are just an ignorant waste, and my Xu family has been in the silk cloth business for decades, and the dyestuff is the best thing. This golden dye formula is my favorite. He Qianqian worked hard to develop it himself. I don't know how much human, material and financial resources were spent. It took a few years. We hid this secret and wanted to surprise the monarch's weaving house. However, I didn't expect you to eat Climbing things outside, not only stealing my property, teasing my maid, but even stealing the dye formula that is related to my family's lifeline."

Then Patriarch Xu said coldly, "Qianqian, how important is this new formula, why did you put it in the drawer?"

Xu Qianqian said: "I'm sorry father, I had complete trust in Shen Lang before, I didn't know he would do such a thing."

Then, she looked at Shen Lang and said, "When you were in the Xu family, there were servants who bullied you, so I whipped them and ordered anyone who dared to speak ill of you to be thrown out of the house. You were ignored in the Xu family, I I don't despise your low intelligence and stupidity. I come to talk to you every day. I'm so good to you, why do you do such a thing? Even if I abandon you for revenge, it's just revenge on me, why should you cut me off? The lifeblood of the family? Besides, if you don't do those scandalous things, how could my Xu family drive you out?"

As soon as these words came out, the officials present looked a little weird.

However, they believed half of the words of Patriarch Xu and Xu Qianqian.

The Xu family was indeed proficient in silk dyes, otherwise their silks would not be exclusively for the monarch's weaving house. They also heard about Shen Lang's reputation as an incompetent, incompetent child, so they also firmly believed that this new formula was researched by the Xu family and stolen by Shen Lang.

Shen Lang said slowly: "You have no evidence, and I have no evidence, but everyone will believe that this new formula was researched by your Xu family, and I have a hard time explaining it."

Patriarch Xu smiled inwardly: "It's good that you know."

This thing is really cool, not only did he get a wonderful golden yellow dye formula for nothing, but also justifiably sent Shen Lang to prison.

Suddenly, Patriarch Xu said coldly: "The truth has been revealed, arrest people! Under torture, I don't believe that this bastard does not confess."

"Why is the Xu family in such a hurry?" Shen Lang said with a smile: "Although it's hard for me to argue, but it's easy to prove this!"

Then, Shen Lang looked at Xu Qianqian and said, "Miss Qianqian, you are proficient in dyes, so let me ask you, which color is the most difficult?"

Xu Qianqian said: "The most difficult color is of course purple."

That's right, the hardest color to dye in ancient times was purple, not yellow.

Of course, it is not impossible to dye purple. In ancient China, comfrey root was used to make purple dye, but the color was inferior. Afterwards, use the dyed conch like violet to make purple dye, and the purple looks better.

Qi Henggong liked to wear purple clothes. At that time, one piece of purple cloth was worth five pieces of white cloth, which showed that it was expensive and rare.

In the West, seashells are dyed to make purple dye. In ancient times, the last queen of the Ptolemaic Dynasty also liked this purple very much. Not only clothes, but even sails were dyed purple.

But whether it is dyeing conch shells or dyeing sea shells to extract purple dye, the cost is extremely staggering. Just one gram of dye requires three hundred dyed sea shells.

Therefore, purple dyes were extremely rare and expensive in ancient times on Earth.

At this time, in the world where Shen Lang lives, no way has been found to extract purple from dyed seashells and conch shells, so where does the purple dye in this world come from? It is directly made by mixing blue dye and red dye.

But the dyeing effect is really uncomplimentable, because the dyes of these two colors are not very clever in themselves. Although they are mixed with purple, the effect is even more complicated. The first is uneven dyeing, the color is dull and poor, and the most important thing is that the wet fastness of the two dyes is different, so purple silk tends to fade easily.

Shen Lang said: "Is purple dye more difficult than yellow dye?"

Xu Qianqian said: "Of course!"

Purple dye is hailed as an insurmountable problem by the cloth and silk world of this world.

Shen Lang said: "It's very simple to prove whether I stole this golden yellow dye. Let's conquer the purple dye together. Your Xu family uses the power of the whole family to make purple dye. I only have one person and no money. I use the simplest and lowest. The cost of making purple dye, and then in front of several people present, to see who made the most beautiful purple? How?"

As soon as these words came out, several officials present nodded in agreement with this method.

Xu Qianqian and Xu Patriarch looked at each other, they wanted to directly put Shen Lang in prison, and didn't want to compete at all.

Suddenly, the Xu family sneered: "Why should we promise you? Waste our time, take it directly, and if you don't believe it, you won't confess in prison."

If there are no officials present, then Shen Lang's method will not work, but there are several officials present, and officials still need some face, especially one of the officials, Shen Lang has a memory and understanding of him.

So, Shen Lang kept looking at the youngest official. If he remembered correctly, this person was in charge of the prison in Xuanwu City, and he had a little bit of energy on his body not long after he was raised.

Seeing Shen Lang's gaze, the young official said: "Patriarch Xu, let him try it out, if he can't make a better purple fuel, it proves that he stole the golden yellow dye formula before, just grab it directly. That's it."

As soon as the young official opened his mouth, the head of the Xu family suddenly turned cold and took a serious look at the official.

However, even if he is unwilling, it is not easy to refuse, after all, the official has already spoken.

And he never believed that Shen Lang would dye anything, and no one knew Shen Lang better than Xu Qianqian. This yellow formula may be from which corner Shen Lang got it. In this regard, the Xu family is the most professional, so Shen Lang will definitely lose, and die sooner or later.

"That's Lord Yilin's." Master Xu said, "How long can this waste be dragged on?"

Shen Lang said: "If the purple dye I made at low cost is better, what does that prove?"

Xu Qianqian said unwillingly: "That proves that you didn't steal the golden yellow dye formula, but we wronged you."

Shen Lang said: "Then you will have to admit the slander, and you will have to apologize to me."

Patriarch Xu said coldly, "Let's talk about it when you win."

Shen Lang said: "That's good, it's limited to three hours! After three hours, we will compete with each other, and the truth will be revealed!"

"Yes!" said an official present.

The head of the Xu family said: "Go to the house immediately, select the best master workers, and Qianqian will sit in charge and create the best purple dye incomparably."

"Yes!" Xu Qianqian said.

This time, the Xu family will use the power of the whole family.

And Shen Lang was still alone, and said to Lin Mo, "Boss Lin, I'm going to borrow your kitchen again."

"Of course." Lin Mo said.

...

After Shen Lang entered the back kitchen, he took out his secret weapon.

The best source of purple dye, litmus lichen.

This is a kind of moss, it is everywhere, it is worthless at all, but the purple made of this material is the most vivid, lively and beautiful.

In eighteenth-century England, Cuthbert stumbled upon a bryophyte that could make purple dye, and it worked incredibly well.

Since then, this purple dye extracted from litmus lichen has dominated the dye industry for more than a hundred years. It was not until the chemical industry developed by leaps and bounds that there was a lower-cost synthetic purple dye.

So why did Shen Lang prepare litmus lichen in advance?

Because this is his preparedness.

Although the possibility of Lin Mo betraying him is very small, it is not that he has not made such mental preparations before, so he secretly prepared a killer, and now he really uses it.

Shen Lang crushed the dried litmus lichen and boiled it with coal ash and urine.

A sheer purple color was quickly obtained.

Next, brighten with alum.

Quick, low cost, but beautiful and wonderful purple dye is out.

Compared to the purple dyes in this world, I don't know where Gao Ming has gone.

Then, Shen Lang picked up a piece of colorless silk and dyed it in the dye. After dyeing, he put it in the sun to dry it.

Soon, purple silk appeared.

What a wonderful purple, so bright and vivid, noble connotation.

Completely killed the purple silk of this world.

However, what Shen Lang wants to do is not just purple.

Just a purple color can win the Xu family, but it's not good to be slapped in the face.

He seized all the time and directly used the materials of Lin Mo's house to create seven kinds of dyes, to dye the most gorgeous, mysterious, and magical rainbow silk!

That is, the colors of red, orange, yellow, green, blue, indigo and purple are dyed on the same piece of silk. Using the method of dividing and segmenting for dyeing, if the speed is fast enough and the movement is accurate enough, the resulting rainbow silk will be extremely stunning and elegant.

Although he is not a professional dyer, he is indeed a dye enthusiast, but when he was in the Silk Museum, he played for more than half a month, completely indulging in a very interesting interest class for a long time.

When Shen Lang joined the Xu family before, he saw workers dyeing cloth every day, leaving relevant memories.

The most important thing is that the alien notebook computer in Shen Lang's mind has information, and every step and every material is written clearly.

Therefore, although he can't be the most professional and best, it is enough.

Three hours later, Shen Lang's purple silk and rainbow silk were all dyed.

Purple silk is enough to win Xu Qianqian.

And this rainbow silk is completely a killer.

This is something the world has never seen before. This amazing effect is enough to crush the silk of the Xu family into slag!
