These two were used for anti-counterfeiting, and she asked Boss Shen to depict them with the special pigments she provided.

Tang Jingyun had been thinking about it before, the Red Flame Flower, Snow Jade Golden Lotus, and Beast Repellent Grass were too effective, and it would be difficult for the pharmacy's business to be hot in the future.

At that time, someone will definitely hit the idea on the ointment, but I am afraid that some messy imitations will be made, which will damage her signboard.

But the ancient anti-counterfeiting signs are not easy to get, Tang Jingyun thought about it, or pinned his hopes on special pigments.

Previously, Tang Jingyun exchanged the pigment seeds of three life plants from the three planes.

One of them is the silver jade flower, which resembles the tung oil tree.

The fruit, like the animal repellent grass, contains a white powdery substance.

It looks white and is colorless and transparent when dissolved in water, but after being burned by a flame, it can permanently adhere to the surface of any object.

Moreover, when its coloring is completed, the color is pale silver, which is not easy to distinguish with the naked eye.

However, when heated, the color will deepen, the hotter the darker the color, and the lighter the color will be when cold.

This is not what Tang Jingyun values the most.

The main function of this pigment is that once it is attached, it will never volatilize, and the color shade will always be reversible.

Take it to anti-counterfeiting, very safe!

For this pigment, Tang Jingyun spent a lot of money.

However, the first batch of white porcelain boxes in cooperation with Boss Shen are not needed.

However, at this time, the reputation of the pharmacy has not yet risen, so there is no need to worry for the time being, it only takes a month, and the silver jade flower can come in handy.

Because this pigment was provided by Tang Jingyun himself, Boss Shen said that there was no problem, and he would let people send the pigment when the time came.

After negotiating the details of the cooperation, Tang Jingyun quickly paid the deposit and signed the contract.

Leaving from Boss Shen, Tang Jingyun and Zhao Dakui went directly to the county seat.

She hadn't taken a good look at her shop yet.

The workers in the store were decorating, and Mrs. Zhao was at the door directing two workers to carry a plaque covered with red cloth inside.

"Is the plaque ready?" Tang Jingyun asked.

When Zhao Niangzi saw Tang Jingyun coming, she smiled and said straightly: "It's done, no, I just sent it." ”
