What Zhang Che was looking forward to the most was how fast the Darkfiend Abyssal Dragon would be after advancing.

At that time, surpassing the speed of sound shouldn’t be a problem at all! Perhaps, if the Darkfiend Abyssal Dragon made a sufficiently big break through, he wouldn’t just exceed the speed of sound. He might even go further, reaching five hundred meters per second!

As he thought about the future, Zhang Che’s mood became incomparably beautiful. It couldn’t be described with words alone.

However, he’d only find out the end results after some time. As for now, it was better to see what good stuff was in here.

Although the Darkfiend Abyssal Dragon had sucked in the whole pool of the extremely cold creamy white spiritual fluid, the cold aura in this underground cave didn’t decrease by too much.

What did that signify? Naturally Zhang Che was clear about that. Without a doubt, that unknown creamy white spiritual fluid didn’t appear out of nowhere. Surely it was formed from the combination of the unique terrain here and some special minerals.

Minerals that could produce such spiritual fluid naturally wouldn’t be anything ordinary, either!

Done thinking, Zhang Che immediately went into motion, controlling the scarlet and white sword to slash at the pit.

The scarlet and white sword’s attack power was terrifyingly high. Even epic-quality exotic beasts couldn’t withstand its sharpness. Although the rocks here weren’t simple, they too were cut easily.

As the sword light streaked about, large pieces of rock were hacked away.

“Damn, am I possessed or what!” Zhang Che suddenly slapped his own head after controlling the sword light to slash at the rocks for a while.

After not using the Purple Crystal Tortoise to scour for minerals for a long time, and heavily relying on the scarlet and white sword’s high attack, Zhang Che actually forgot that he had the capable little Purple Crystal Tortoise to mine for him.

He recalled the sword light, then immediately ordered the Purple Crystal Tortoise to sink into the underground cave’s rock strata, digging out all the minerals hidden inside.

At this time, the elemental queen, who had been responsible for standing guard, suddenly said, “Master, there isn’t any more danger here. Can you let me leave this place first? This servant doesn’t like the environment here.”

Zhang Che turned to look at her. He saw the elemental queen’s face slightly scrunched up, looking at him in anticipation.

Right. She was a fire spirit, after all. Of course she’d feel uncomfortable in this land of extreme cold.

Previously, they needed her to be on guard against any possible danger that might appear. Now that it was clear there wasn’t a single powerful exotic beast in this underground cave, it was a given that the elemental queen wasn’t willing to remain here any longer.

“Alright. You go wait outside the underground cave. I’ll join up with you after the Purple Crystal Tortoise digs out the minerals.”

Zhang Che was naturally understanding of this. He nodded and agreed to her request.

The Purple Crystal Tortoise still needed some time to finish digging. Of course Zhang Che wouldn’t force the elemental queen to wait with him here.

“Thank you, Master!” the elemental queen let out a long sigh of relief. She bade farewell to Zhang Che and quickly ran back along the tunnel they had come from.

After sending off the elemental queen, Zhang Che was in no hurry. He stood and waited quietly. All of a sudden, the Scarlet Flame Drake let out a soft bark when it saw the elemental queen leaving.

As a fire-attributed subdued beast, the Scarlet Flame Drake hated this environment to the extreme, too. It barked as a reminder to Zhang Che, wanting its master to recall it back into his spiritual sea.

“Fine, you’re all so delicate. Can’t even take a little bit of suffering,” Zhang Che shook his head helplessly. He recalled the Scarlet Flame Drake back into his spiritual sea with a wave of his hand.

The entire cave fell into an endless darkness.

“Shit, I shouldn’t have let the dog come back!”

Zhang Che was depressed. Although there wasn’t any more danger, waiting alone in this darkness left him feeling uncomfortable.

-Forget it. I’ll go wait outside the cave too.-

Shaking his head, Zhang Che gave another order to the Purple Crystal Tortoise, telling it to meet him at the cave entrance when it was done digging for minerals. He followed the tunnel he came from and quickly retreated from the cave.

——

After returning outside, the extremely cold feeling seemed to have disappeared without a trace. Zhang Che relaxed all over, feeling much more comfortable.

He stowed his beast card armor and chatted with the elemental queen.

—-

After waiting for close to an hour, they finally saw the Purple Crystal Tortoise emerging from the ground.

However, the Purple Crystal Tortoise obviously seemed to be in a bad state. The purple armor on the surface of its body was dyed with a faint layer of white frost.

“Could it be that there are still exotic beasts in the cave’s rock strata?” Zhang Che widened his eyes. He saw the Purple Crystal Tortoise opening its mouth, and a pile of white jade-like mineral poured out from it, accumulating into a pile half as tall as a man.

As the white jade-like mineral appeared, the surrounding temperature quickly fell, like winter had suddenly descended on them.

“What a concentrated force of extreme cold!” Zhang Che finally understood why there was a layer of frost on the surface of the Purple Crystal Tortoise’s armor. The pile of mineral in front of his eyes was the cause of it.

“This thing seems to be even higher grade than the fire crystals!” Zhang Che immediately grew excited.

No matter what, this was an extremely rare mineral. It would definitely be very useful.

“Since these minerals contain such dense aura of extreme cold, I’ll call you Dark Yin Crystals,” Zhang Che casually named the minerals, before stowing them away in the Nirvana Snake King’s spatial storage.

It went without saying that their applications would only be known after he returned to Bei Du and had his father-in-law’s men conduct research on them.

At this moment, changes suddenly happened in his spiritual sea.

Concentrated rainbow light suddenly shone from above the rainbow crystal, enveloping the light that represented the Darkfiend Abyssal Dragon.

“Hmm? Could it be that the creamy white spiritual fluid wasn’t enough to let the Darkfiend Abyssal Dragon advance in quality, and so the rainbow crystal gave it a hand?”

After thinking things through, this seemed like the only possibility.

With that, however, Zhang Che looked forward to the end results even more.

“Then, since the Darkfiend Abyssal Dragon’s breakthrough in quality is a given, I wonder if he will advance in level as well…”

——

The sky gradually darkened.

Zhang Che decided to get back inside the cave, ready to set up camp here tonight.

Since the Dark Yin Crystals that emitted the extremely cold aura were already dug out, it shouldn’t be very cold inside the cave anymore.

Indeed, after entering the cave, although a tinge of coolness could still be felt, it was no longer to the extent of being unbearable.

Thus, Zhang Che prepared tonight’s roasted meat party while waiting for the Darkfiend Abyssal Dragon’s advancement.

He didn’t wait too long. When the meat was roasted on the skewers stabbed into the wall to fragrant perfection by the elemental queen, the Darkfiend Abyssal Dragon’s light in Zhang Che’s spiritual sea finally emerged from its cocoon.

His pet finally had supersonic flight speed!
