I continued to buy treasure chests.

"Open."

Open the treasure chest directly.

"Ding, congratulations on obtaining 100 catties of Green Willow Spirit Crystal Stone (Green willow crystal stone, mainly used as pigment, containing rich spiritual power. When used to grind ink and paint on a painting, it can give the painting a touch of life)."

Look at the crystals that were obtained this time.

Gu Xuan nodded in satisfaction.

This is a willow-green crystal.

It also looks beautiful when used as a pigment.

But most importantly, using it will make people feel a sense of life.

Moreover, the plants on the Xuan paper look as if they have come to life.

Gu Xuan was very surprised by this.

I'm also very curious to see what the effect will be.

At this moment, Gu Xuan looked at the painting on the table in front of him.

Then I looked at the paint on the interface.

"I really have to try it out later and see what the effect will be."

Gu Xuan also became looking forward to it.

Store the Green Willow Spirit Crystal in your system space.

Then I continued looking at the interface.

"Another treasure chest, please."

Continue buying treasure chests.

Restart.

"Ding! Congratulations on obtaining 100 jin of Yellow Crystal Spirit Ore (a yellow crystal pigment with a wide range of uses. It also contains strong spiritual energy and can enhance the beauty of paintings)."

Pigment ore was found again.

Gu Xuan was still very excited.

He directly added it to the system space.

I didn't look at it much.

"My luck has turned, so I'll try another color."

Then continue opening treasure chests.

"Ding! Congratulations on obtaining 100 catties of Moonstone Crystal Ore (Moon-white crystal ore, which has absorbed the essence of moonlight for a long time, making it very lively. Using it to paint will make the painting even more lively)."

See the items in the treasure chest.

Gu Xuan said with a smile.

"continue."

Purchase the Golden Treasure Chest again.

Open it directly.

"Ding! Congratulations on obtaining 100 jin of Azure Crystal Spirit Ore (a type of blue crystal ore with a strong concentration of spiritual energy within it. Its color is extremely pure, making it a top-grade blue crystal)."

Gu Xuan smiled slightly when he saw that he had won the color this time.

"continue."

Gu Xuan continued to buy treasure chests without even thinking.

"Open."

I couldn't wait to open it.

"Ding! Congratulations on obtaining 500 catties of Immortal Crystal Rice (top-grade Immortal Crystal Rice with a very unique flavor)."

This time, it wasn't pigment ore that was mined.

Upon seeing this, Gu Xuan knew that his luck had run out.

However, I was relieved this time.

"Not bad, five colors are enough for now."

In fact, Gu Xuan also had a premonition.

After all, having drawn five colors in a row, one's luck is pretty much exhausted.

I glanced at the interface.

Gu Xuan has no intention of buying any more treasure chests.

I turned to look at the system repository.

Five kinds of pigment minerals are placed inside.

Then they took out one piece of each of the five types of ore.

Each piece is perfect and extremely pure, making them very rare mineral pigments.

Now, however, some steps are required, such as grinding ink.

The good thing is that these ores are very pure and are spirit ores, so they don't require many processing steps.

It doesn't need to take too long.

It can be used directly after it is made.

This is also why we chose spirit ore.

Gu Xuan took out five different colored ores.

This piece can be used to make a lot of ore.

These ores can be used for a very long time.

After the ore was removed, some other tools were then used.

These tools are used for grinding and making pigments, and of course, you also need spiritual spring water.

This time, Gu Xuan used the Immortal Spirit Spring Water directly.

This will produce better results and allow for more vibrant colors.

After setting everything in place, begin making the paint.

It's only been a short time since we started making it here.

Fang Shiqing and Nangong Jin then brought Wanwan over.

Fang Shiqing called out.

"Why are you here so early?"

Gu Xuan looked up at the three of them.

"You guys are up quite early. I thought you were going to rest for a while."

Nangong Jin said.

"We slept so comfortably here that we were fine lying down, so we came over."

The three of them came to Gu Xuan's side.

Just sit down.

He looked at Gu Xuan with curiosity.

"What are you doing?"

Before Gu Xuan could speak, Wanwan spoke up loudly.

"I know."

Fang Shiqing and Nangong Jin looked at her.

"Wanwan knows, then tell me what your brother is doing."

"My brother is making paint."

The two became even more curious after hearing what Wanwan said.

He turned to look at Gu Xuan.

Fang Shiqing asked curiously.

"Is Wanwan right?"

Gu Xuan nodded.

"Yes."

Nangong Jin became even more curious.

"pigment."

He casually picked up a piece of ore from the side.

"Isn't this just ore? Are you going to use it as pigment?"

Gu Xuan smiled and then looked at Wanwan.

Wanwan smiled when she saw Gu Xuan's gaze.

"Sister, you're so silly. The paints we use for painting are made from ground minerals."

Nangong Jin looked incredulous.

"No way."

He then looked at Gu Xuan.

Gu Xuan nodded.

"Yes, we used mineral pigments before."

"When using this to paint, is it possible to use a ready-made good one?"

Gu Xuan explained.

"Actually, the best is still pigment minerals. The colors are pure, and they won't change or fade after painting. They are the most perfect pigments, and they are not cheap."

Fang Shiqing said.

“I’ve heard of this too; many famous masters are looking for this kind of pigment.”

Gu Xuan nodded.

"Yes."

Nangong Jin stared at Gu Xuan.

"I'd like to see just how amazing it is."

"good."

Then the group helped Gu Xuan with the production.

The pigment ore initially requires crushing and grinding, which is quite troublesome.

It is also very physically demanding.

Gu Xuan did all of this.

After Gu Xuan went through more than a dozen grinding processes, he handed the ground pigment to a few people and asked them to put it in water and start stirring. This was to remove impurities. Although these minerals were very pure, he could not guarantee that there were no impurities at all.

Of course, it's also necessary to remove those colorless crystals.

This step also takes time.

But the group had a lot of fun.

We chatted while we worked.

After they finished, Gu Xuan came next.

The pigment contains a high amount of water.

Moreover, ordinary ores require sedimentation.

But these ores don't need that, because they are made with Fairy Spring water, which can be heated directly to make them evaporate.

This is no different from letting it settle and then drying it.

After completing this step, we will add something else to make the color even brighter.

Of course, the things that were added had already been purchased.

Gu Xuan did all of this.

Adding it completes the color creation.

Then place it in a porcelain dish containing pigments.

All five colors are now complete.

The final products were all made by Gu Xuan, and the three of them were very curious about them.

They all gathered around to take a look.

They were all stunned when they saw such a beautiful color.

"This color is so beautiful. You can see its brightness and beauty even in the porcelain dish. It's amazing. What kind of mineral is this?"

"This is a rare mineral, very rare, and a single piece can cost hundreds of thousands."

When Gu Xuan revealed the price, the two were even more shocked.

"I never expected that."
