The Wang family's mineral vein.

"This is the Wang family's mineral vein. The unfinished profound crystal stones that these laborers shuttling back and forth are carrying. After being sent out from the cave, they will be collected by people sent by the Wang family. Then they will be processed and finally turned into the profound crystal stones we usually use." Seeing Fang Chen stop and observe back and forth, Wan Yuxuan explained.

"So that's it. For this profound crystal stone vein, each of your four families occupies one place. Up to now, what is the highest grade produced?" Fang Chen looked at the busy laborers and asked expressionlessly.

"Of course it's top grade." Wan Yuxuan said it as a matter of course. Then, as if thinking of something, she continued, "However, I heard that there seems to be a higher grade of profound crystal stone above top grade. But I'm not sure if it's true. After all, I haven't seen it."

"Oh." Fang Chen responded faintly. Lei Wa said that the heavenly-grade profound crystal stone is nearby. But the spreading profound crystal stone vein in front of him is so huge...

"I'll go over there and take a look. Wait for me here."

Seeing Fang Chen leave after saying that, Wan Yuxuan raised her right hand and wanted to say something. Her lips moved a few times but in the end, she only said, "Okay."

Although the relationship between the two of them is much stronger than before, it is still far from being at the point where they can be completely honest with each other. Wan Yuxuan is still very clear about this.

At least, it's a good start, isn't it? Looking at Fang Chen walking farther and farther and finally disappearing at the foot of the mountain, Wan Yuxuan's heroic eyebrows stretched and the corners of her mouth slowly rose in a light smile.

Walking faster and faster. It wasn't until he looked into the distance and couldn't see any people around that Fang Chen released Lei Wa.

After walking for so long, Fang Chen suddenly found that this profound crystal stone vein seemed endless. Wherever he went, it spread. After thinking for a while, he still decided to find a more hidden place and let Lei Wa find it.

"Wow, master, did you miss me?"

Seeing Lei Wa, who was just released and was hugging his leg with a playful smile, Fang Chen couldn't help but twitch the corner of his mouth. Then he stretched out his finger and tapped Lei Wa's little head and said, "Didn't you say there is a heavenly-grade profound crystal stone here? Try and see if you can sense the specific direction."

Hearing this, Lei Wa was slightly stunned. Then he looked around. "Wow, master, you've come to the profound crystal stone vein!"

After dancing around for a while and seeing Fang Chen's face slightly change, Lei Wa quickly said, "Okay, I'll sense it now." After saying that, Lei Wa closed his eyes. The blue light on his body surface, like a flame, began to jump.

Not long after, Lei Wa opened his eyes. Staring blankly at the towering mountain peak not far away. After being stunned for a while, he then turned to look at Fang Chen and said in surprise, "Master, there really is a heavenly-grade profound crystal stone. There really is!"

Seeing this, a look of joy couldn't help but appear on Fang Chen's face. He picked up Lei Wa and put him on his shoulder. "Show the way."

Under Lei Wa's guidance, Fang Chen carefully looked around and walked towards the mountain not far away. Lei Wa was also not idle. He kept sensing the specific location of the heavenly-grade profound crystal stone.

"This is it." After a long while, Lei Wa finally pointed at what was in front of him and said.

"Here?" Feeling the heaven and earth profound energy slowly overflowing from the mountain under his feet, Fang Chen squatted down. Took out the Guiyuan sword and thrust it hard. Even with the sharpness of the Guiyuan sword, without using profound energy, the sword body only barely penetrated less than half.

Seeing this, Fang Chen couldn't help but frown and say, "Is it deep?"

"Very deep." After continuing to sense for a while, Lei Wa nodded thoughtfully.

"How deep?" Fang Chen was stunned for a moment. Then he looked at Lei Wa.

"Well... it seems... in the central part of the mountain." Lei Wa frowned. After pondering for a moment, he stared at Fang Chen with a pair of innocent big eyes.

"Oh." Fang Chen stood up and took back the Guiyuan sword. After looking around for a while, he found that the place he was in was almost at the top of the mountain. After thinking for a while, he asked, "Can you sense the situation inside the mountain?"

"Yes." Lei Wa raised his little head, looking like he was the strongest. "There are many people down there. But for some reason, they all avoided the location where the heavenly-grade profound crystal stone is."

"Avoided?" Fang Chen touched his chin in confusion. When mining this profound crystal stone vein, wherever there is profound crystal stone, there will more or less be fluctuations of profound energy. If there are top-grade and supreme-grade profound crystal stones, not to mention people with high cultivation levels, even ordinary people can clearly feel the obvious overflow of profound energy.

Logically speaking, where the vein is mined must be determined after being sensed by people with high cultivation levels first. The profound energy contained in the heavenly-grade profound crystal stone is the purest. Such a situation shouldn't occur.

Right, the laws of the Great Dao! The heavenly-grade profound crystal stone contains the laws of the Great Dao! Fang Chen suddenly remembered. In his previous life, he had also seen heavenly-grade profound crystal stones. If he didn't see it with his own eyes and touch it in person, he would definitely not be able to sense what was different about this heavenly-grade profound crystal stone.

Lei Wa said that this heavenly-grade profound crystal stone is in the central position above the mountain. Then when the Wan family mines, avoiding it can only mean that they feel that there is no fluctuation of profound energy here and that if they dig here, it will collapse.

Thinking of this, Fang Chen couldn't help but feel a bit troubled as he touched his chin. If he forcibly punches through from here to take the heavenly-grade profound crystal stone, it will definitely cause the mountain to collapse. In this way, not only will it kill the people inside, but the commotion will also be too great. Once it attracts the attention of the strong people of the Wang family, it will be difficult for him to escape.

Then, Fang Chen looked up at the top of the mountain. A thought flashed through his mind and he took Lei Wa and walked up.

"Here? Which place is closer to the heavenly-grade profound crystal stone, here or the place just now?" After reaching the top of the mountain, Fang Chen asked.

"This place is closer." After sensing for a while, Lei Wa looked at Fang Chen in confusion.

After hearing the answer, the corner of Fang Chen's mouth slowly curved up. Then he circulated his profound energy and thrust a sword downward. The sword body instantly completely penetrated into the mountain.

"Not bad. This is feasible. And the mountain will not collapse. But for your current strength, it is still a bit difficult." The spirit of the artifact, who had been watching all this from the beginning, immediately understood after seeing Fang Chen's action.

That's right. The method Fang Chen thought of at this time was to use great force to open a passage from the top of the mountain down to the place where the heavenly-grade profound crystal stone is. This way, it is not only time-saving and labor-saving but also the mountain will not collapse because of it. Once he gets it, even if it attracts the attention of the strong people of the Wang family, he will have enough time to escape.

"So I need your help." After saying that, the smile on Fang Chen's mouth became even stronger.

The spirit of the artifact couldn't help but twitch the corner of his mouth. So you were waiting for me, right? Thinking of this, he couldn't help but say helplessly, "Okay, then I'll help you."
