Bai Yue opened her mouth and began to hum softly. Her beautiful, ethereal, and faint singing voice immediately caused Ye Feng's soul to tremble slightly.

However, Ye Feng's thoughts shifted, and the tremor in his soul immediately stopped.

"Indeed, this magical artifact is quite impressive!" Ye Feng laughed.

Bai Yue changed back to normal and took off the magical artifact, playing with it with great affection.

"Although it's only a fifth-grade spiritual artifact, it can transform into twenty-four kinds of demonic beasts and even unleash some of their innate divine abilities. This spiritual artifact is indeed very powerful, and the crafting technique is extremely skillful!" Bai Yue clicked her tongue in admiration, praising it without reservation.

Ye Feng laughed and said, "If in the future, all the demon beast cores on this spiritual artifact are replaced with eighth, ninth, or even tenth grade ones, that would be truly heaven-defying."

"Yes, he's practically invincible in his realm!" Bai Yue nodded.

However, Ye Feng then said, "But the higher the grade of the demon beast's inner core, the more difficult it will be to refine, and the greater the risk of failure will be. Once it fails, the entire spiritual artifact will be destroyed, so this idea is actually very difficult to realize."

"But you can definitely do it, right, cousin?" Bai Yue asked expectantly.

"We are somewhat confident that we can do it, but we are not certain that we can do it," Ye Feng corrected.

"That's already amazing! Clan brother, I'm counting on you from now on. You must help me upgrade the grade of this spiritual artifact!" Bai Yue said, and she hugged Ye Feng's arm tightly, her warm and soft breasts pressing and rubbing against Ye Feng's arm.

"Let go first. I didn't say I wouldn't help you. Why are you doing this?" Ye Feng frowned.

Bai Yue reluctantly released Ye Feng, muttering softly, "Brother, you're being too polite. In this vast world, there are probably only two dragons, you and I..."

"Stop talking." Night Wind interrupted Bai Yue.

Bai Yue's face showed a sad expression, which made Ye Feng feel a little sorry for her.

But Ye Feng didn't offer any words of comfort. Instead, he turned and left, saying, "I'm going to check on things at the mine. You stay home and cultivate. Don't be idle."

"I understand," Bai Yue said disappointedly.

Perhaps it was the attraction between people of the same kind, but Ye Feng did feel that his feelings for Bai Yue were growing stronger.

Just now, Bai Yue flirted with Ye Feng, and he even felt a surge of desire, wanting to immediately whisper sweet nothings to Bai Yue.

However, he managed to control himself.

Mu Qing and Ling Xuan are still waiting for him in the real world. How can he be intimate with other women in the Yin-Yang Great World?

Even if she is a dragon and has the mission of procreation here, it's still not allowed!

As soon as Ye Feng arrived at the entrance of the mine, he saw Wang Dachun rushing out of it in a flurry of activity. The silly boy was covered in dust and dirt, as if he had just rolled around in a pile of dirt.

"Young Master Gong, you've arrived! Just what I was looking for!" Wang Dachun said with a smile.

"Have you made any discoveries?" Ye Feng asked.

"A discovery has indeed been made, and it's a major one!"

Wang Dachun grabbed Ye Feng's hand and pulled him towards the mine.

But the night wind was faster than him, and it lifted him into the air, carrying him away through the narrow passageway.

This incredible speed terrified Wang Dachun so much that his heart nearly jumped out of his chest!

"Young Master Gong, slow down! I can't take it anymore, I can't hold on... I'm going to crash!"

Just as they were about to crash into the cave wall, Ye Feng suddenly changed direction and immediately carried Wang Dachun away in the other direction.

Before long, Ye Feng brought Wang Dachun to Wang Zongde and the others.

As soon as he landed, Wang Dachun sat down on the ground with a thud and vomited violently.

"What's going on?" Wang Zongde asked, looking completely bewildered.

Wang Dachun wiped his mouth and said with lingering fear, "Young Master Gong just flew me here..."

Wang Zongde said "Oh," and immediately understood why his silly son was vomiting so badly. Then he said angrily, "It's your good fortune that Young Master Gong took you flying. You have no luck at all. I'm so angry!"

The night wind paid no heed to Wang Zongde and Wang Dachun.

He strode over and looked down at the ore that Wang Zongde and the others had dug out.

The ore piled up haphazardly outside looked no different from the ore mined yesterday, with very little mineral content.

However, the innermost small portion of the ore was covered with shimmering purple light.

“This is purple gold ore,” Ye Feng said.

The three men smiled broadly and gave a thumbs-up, saying, "Young Master Gong has a good eye. We hadn't even said anything yet, and you already figured it out at a glance."

“I’m very knowledgeable about all kinds of refining materials, so of course I can tell,” Ye Feng said.

Ye Feng is not only an alchemist, but also a weapon refiner. Purple gold is a relatively precious weapon refining material. If he doesn't recognize the sun, he must have risen in the west!

“You’ve struck a vein of funds, which means you’re not far from the spiritual vein beneath the hills. Keep digging, don’t stop,” Ye Feng said.

"yes!"

Wang Zongde and his team immediately began digging with all their might, without stopping for a moment.

Two hours later, more and more purple gold ore was dug out, and even black tung gold ore appeared!

Black Lotus Gold is a more precious refining material than funds, and it can be used to refine ninth-grade and even tenth-grade spiritual weapons!

“This is Black Epiphyllum Gold, which is even more precious than Purple Gold,” Ye Feng said.

After a pause, Ye Feng continued, "Don't sell these ores yet, otherwise they will attract the attention of others. I'll give you some storage rings now. You'll need to bind them with your blood and store all the ores in the storage rings. When we leave here, you can sell the purple gold ore to Old Liang, but you can't sell a single piece of the black hibiscus gold ore. That stuff is too valuable."

Wang Zongde nodded repeatedly.

The three of them knew they had struck gold, and their faces were flushed with excitement. They wanted to do a few somersaults to release their excitement and exhilaration.

But Ye Feng was still not satisfied and said, "Keep digging, what I want is still inside."

Could there be something even more precious inside?

Wang Zongde and others then continued digging.

No one knows who brought down the pickaxe, but suddenly the surrounding spiritual energy became abundant.

We've finally found a spiritual vein!

If a spiritual vein is not discovered, the spiritual energy of heaven and earth will not leak out!

Not only Ye Feng noticed this, but Wang Zongde and several other martial artists also guessed it.

"Alright, you can stop now. Starting tomorrow, you'll dig somewhere else. Don't dig here anymore," Ye Feng said.

Wang Dachun scratched his head and said, "Why? There are so many good things here, why not keep digging?"

"The purple gold ore you just mined is enough to ensure you live comfortably for decades to come. Aren't you satisfied? And those black hibiscus gold ores are far more precious than purple gold ore," Ye Feng said.

Before Wang Dachun could say anything more, Wang Zongde slapped him on the head.
