"Sorry, the old shopkeeper is so clumsy. It turns out he is a cousin!" The shopkeeper bowed respectfully, then looked at Ling Zhirong and said, "Young Master, look, the color in this pool is a bit strange."

Ling Zhirong looked at me, frowned, turned her head to look at Qigui: "I'll go to the edge of the pond, you can stand here and watch me, don't walk away."

Qi Gui nodded, then watched Ling Zhirong lift her robe and jumped directly onto the pool of blue paint.

Her thoughts were still concentrated in what Ling Zhirong said just now, "Crazy Cousin", which implies that she is also his cousin?

Murong Chifan didn't tell her about such an important relationship!

She never knew what to call Ling Zhirong, but fortunately she didn't call her anything. If she called her wrong, wouldn't she be exposed?

I suddenly remembered Ling Zhirong, one of the people who knew the snow silk craftsmanship. She just pretended not to be interested in everything just to save her life. Now seeing Ling Zhirong is still good to her, Qi Gui suddenly thought that even if Ling Zhirong didn't let Ling Zhirong tell the snow silk craftsmanship, if she had a way to make him trust her, when he weaved the snow silk step by step, she was watching quietly. She was so smart that she should understand a general idea?

Such thoughts were hovering in Qigui's mind and could not be dissipated for a long time. She just hoped that she could get this soon, wait for Ling Xu quickly, and then the two of them would go home together!

If it is really possible, she doesn't mind, taking risks for love and going home!

Ling Zhirong walked along the edge of the pond to the next to the cloth rack, raised her hand and grabbed the white place and pulled it up, and immediately frowned: "The color is quite strange."

The shopkeeper stepped forward and said, "I originally thought, otherwise I would use this new blue to sell it. But we tried two finished products, and it faded as soon as it was put into water. The color dropped unevenly. After washing the cloth, it turned out to be a flower."

"How could this happen?" Ling Zhirong said: "I'll take a look at the dye."

"good."

Ling Zhirong jumped down from the edge of the pond, and when she passed by Qi Gui, she grabbed her hand and held her to the small warehouse where dyes were stored in front.

Qigui followed him and walked forward. After stopping, Ling Zhirong let her go and began to check the dye very seriously.

The shopkeeper even took out two pigment powders that were strictly blended in proportion to Ling Zhirong. He gently pinched some, rubbed them on his fingertips, and said, "No problem, it shouldn't be! Where did the dyes be purchased this time?"

"It's always Xu Ji. I talked to their boss in the morning. There is no problem with their dye!"

"how so……"

Just as the two were confused, Qigui's eyes lit up: "Where is the water? What about the water that blends the pigment? Is there any problem?"

She remembers that many colors have their own pH values, referred to as pH. For example, the purpleer the grape, the higher the acidity, which is not the acidic taste, but the acidic nature. In this era, most of the dyes are taken from natural pigments and have no chemical additives. Therefore, neutral water can debug these pigments, so there is no problem. If there is a large difference in pH, it will directly affect the pH value of the pigment itself, change the color, or make the color unable to neutralize.

Of course, she could only put these principles in her heart and could not tell Ling Zhirong about them.

The shopkeeper and Ling Zhirong were slightly stunned and looked at her in surprise, as if she didn't expect her to speak.

The shopkeeper smiled slightly: "Miss Cousin, this is the case. The water used in the weaving bureau's pigment mixing water comes from our own century-old well! It is impossible that there is a problem. We have used it for so many years."

"Has it rained recently? It's very heavy, but you didn't cover the well water?" Qi Gui did not give up his point of view.

Upon hearing this, Ling Zhirong looked at her with a deep look and nodded: "Yes, it was raining heavily the day before you came back, just the manhole cover..."

He turned his head to look at the shopkeeper, who admitted frankly: "Not covered! The water from the well was flooded that way, but I still covered it."

"That's right! That rain must be acid rain, with a corrosive effect. It's like the walls of the courtyard we live in, blue bricks and white tiles, and large bluestones. It looks extremely hard and the rainwater cannot be destroyed at all, but after ten or eight years, the walls will become mottled. This is what it means! Therefore, acidic rainwater destroys the quality of the original well water, which will lead to color problems."

"Uh..." The shopkeeper looked at Qi Gui blankly, his expression a little dull.

Qi Gui raised his eyebrows and said, "Don't you believe me?"

“…”

Qigui was a little unhappy, but he didn't want to argue with him. He knew: "Let's do a test, take a basin, fill it with well water, take more pebbles, put them on a plate and boil them together! Use the water from the boiled stones to mix your pigments and see if the color becomes normal!"

When Qigui was in modern times, he followed his parents in a big hotel and watched people use clean pebbles to cook soup or cook dishes. At that time, she was curious, and the waiter explained that the silicate on the stone is weakly alkaline, which can balance the acidity in the body and is good for the body.

Not far away, I looked at this place quietly in the blue mountains, and I don’t know how long I have been standing here.

After Qi Gui finished speaking, when the shopkeeper looked confused, he spoke out: "Do as the lady in the watch! Boil the stones with well water, and use the boiled water to debug the paint!"

"Yes! Master!" After the shopkeeper said that, he went to do it immediately.

Qi Gui was stunned when he heard this, turned around, looked at the man in blue who was getting closer and closer, raised his eyebrows, and Ling Zhirong beside him respectfully called him: "Father!"

"Yes." The man walked over and looked at Qi Gui's face, he was slightly stunned, obviously also a little shocked by her appearance.

However, he quickly laughed happily and said, "I think the singular and beautiful girl of a mother will definitely be charming."

Qigui lowered his head carefully and did not speak.

Her face was dull and pitiful, and her little head was spinning quickly. Both her uncle and uncle's children could be called cousin! And should the person in front of her be called uncle or uncle?

Seeing her expression of grievance and restraint, Ling Zhirong immediately approached her and said, "Don't be afraid, I'll introduce it to you. This is my father Ling Jingchuan, and your uncle!"

Qigui immediately gave a bow: "Hello, uncle!"

Ling Jingchuan smiled and said, "Okay."

While he was talking, the shopkeeper had already come over. Two people followed him, holding a small stove in his hand, and an iron basin was placed on it, filled with pebbles.
Chapter completed!
