But in his intelligent brain, there was also an improved formula from the twenty-first century. Although the main ingredients were the same, the proportions and heat were slightly different, and some other additives had been included.

However, the improved golden formula could only increase the quality by about ten to twenty percent.

The Foster Family had already obtained his formula. Chad Sullivan could win in terms of the yellow color, but he couldn't completely crush the competition.

Therefore, he needed to open up another front.

So Chad Sullivan said, “Of course, if I only beat you in golden yellow dye, it still can't prove my talent. You are an expert in dyes, so let me ask you, which color is the hardest?”

Yvonne Foster replied, “The hardest color is definitely purple. That is the pinnacle of dyeing craftsmanship.”

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

Of course, it wasn't that purple couldn't be dyed. In ancient China, purple dye was first made from the roots of purple grass, but the color was poor. Later, purple dye was made from a kind of dyeing sea snail called ziju, which looked a bit better.

Duke Huan of Qi loved to wear purple clothes. At that time, a bolt of purple cloth was worth as much as five bolts of white cloth, showing how expensive and rare it was.

In the West, purple dye was made from dyeing sea shells. The last queen of the ancient Ptolemaic dynasty was also a huge fan of this purple—not only her clothes, but even her ship's sails were dyed purple.

But whether it was dyeing sea snails or dyeing sea shells, the cost of extracting purple dye was extremely high. Just one gram of dye required three hundred dyeing sea shells.

At this time, in the Great Yan Dynasty, they still hadn't found a way to extract purple from dyeing sea shells or snails, so where did the world's purple dye come from? It was simply made by mixing blue and red dyes.

But the dyeing effect was really nothing to brag about. First, the color was uneven, dull, and clumsy. Most importantly, the wet fastness of the two dyes was different, so purple silk often faded easily.

Chad Sullivan said, “Purple dye is harder than yellow dye, right?”

Yvonne Foster said, “Of course!”

Purple dye was regarded as an insurmountable challenge in the world of fabrics and silk.

“In order to fully prove my talent in dyeing, we will not only compete in yellow, but also in purple,” Chad Sullivan said. “Your The Foster Family can use the full strength of your family to produce these two colors. I am alone, with no money, and will use the simplest and lowest-cost methods to make dye. Then, in front of the adults present, we’ll see whose dye is the best, whose silk is the most beautiful and captivating.”

“I will prove to everyone that in dyeing craftsmanship, I, Chad Sullivan, alone can crush your entire The Foster Family, making the so-called accusation of theft a complete joke.”

“Chad Sullivan, you are truly childish and ridiculous.” Mr. Foster sneered, “Why should we compete with you? Wasting our time—just arrest him, torture him in prison, and see if he still won’t confess.”

Chad Sullivan looked at the officials present and said, “Gentlemen, what do you think of my proposal?”

The officials present were usually well taken care of, and the City Lord’s Mansion had also given them special instructions.

So, when Chad Sullivan asked them, the officials acted as if they hadn’t heard, completely ignoring him.

Chad Sullivan kept his gaze fixed on the youngest official.

This young registrar was in charge of criminal cases in Xuanwu City, and he had the most say in whether or not to arrest Chad Sullivan.

At the same time, Chad Sullivan was recalling his past interactions with this young registrar, especially the things he had said.

If his memory was correct, this official would stand on the opposite side of The Foster Family.

Seeing Chad Sullivan looking at him, the young official hesitated for about half a minute.

Then, he stepped forward and said, “Mr. Foster, let him try. If he can’t beat The Foster Family, it proves his formula was stolen, and we’ll just arrest him.”

As soon as this young official spoke, Mr. Foster's gaze turned cold.

These officials were usually well taken care of and would turn a blind eye to The Foster Family's affairs. This registrar, who was in charge of criminal cases, had just taken office and hadn’t yet accepted money from The Foster Family, but the City Lord had already given him instructions.

Why was he going against the grain now? Didn’t he know that The Foster Family was about to marry into the governor’s family?

Mr. Foster said coldly, “Lord Wang, are you sure?”

The young registrar replied, “I’m sure!”

This young registrar was in charge of criminal cases, so if someone was to be arrested, it really couldn’t happen without his say.

Mr. Foster frowned, about to use the City Lord’s Mansion to pressure the young registrar, but Yvonne Foster tugged at her father’s sleeve.

No one knew Chad Sullivan better than Yvonne Foster. How could he possibly know anything about dyeing?

As for the golden yellow dye formula, no one knew where Chad Sullivan got it from, but The Foster Family had already tested Chad Sullivan's formula, and her family was far more professional than Chad Sullivan, so the yellow dye they produced was even better than his.

As for purple?

The overconfident Chad Sullivan didn’t even know that The Foster Family had just cracked a new purple dye formula, using brand new materials—a revolutionary breakthrough that could instantly outshine all the purple silk on the market.

There was no way Chad Sullivan could win; whether he lost now or later, the result was the same. To confront the registrar over such a trivial matter was extremely unwise.

Receiving his daughter’s hint, Mr. Foster frowned and said, “Then we’ll do as Lord Wang says. Let’s see how long this good-for-nothing can drag things out.”
