Of course, what Zhang Che is most looking forward to is that after the Xuansha Halong is advanced, the flight speed will definitely be greatly improved.

At that time, there is no problem in breaking the sound barrier anyway.

Maybe, as long as the power of Xuansha Minglong is enough, it can not only break through the speed of sound, but also greatly increase it to a speed of more than 500 meters per second.

Thinking of this, Zhang Che's mood was so beautiful that she couldn't describe it with words.

However, it will take some time before we know what the result will be.

Now, let's explore what is good in this place.

Although the pool of milky white spirits emitting extremely cold air has been absorbed by the Xuansha Hades, the cold air in the cave has not been reduced much.

What this represents, Zhang Che is naturally clear.

There is no doubt that the milky white spirit that did not know its name was not born for no reason. It must have been born of the special terrain here, combined with some special minerals.

Then, the minerals that can give birth to this kind of fluid are naturally not ordinary things.

Thinking of this, Zhang Che immediately acted, Yu Shi Chibai Jianguang, and slashed away toward the pit in front.

The attack power of Chibai Jianguang can be called horror. Even the epic quality beast can't resist its sharpness. Although these rocks are not simple, they can't resist at all.

As Jianguang flew, large chunks of rock were chopped down.

"Damn, I'm stunned!"

Just now Yuchi chopped Chibai Jianguang for a while, and Zhang Che suddenly slapped him on the head.

He has not explored with amethyst turtles for a long time, and has relied on the powerful attack power of Chibai Jianguang for a long time. He even forgot that he still has a small mining expert in his hand.

Withdrawing Chibai Jianguang, Zhang Che immediately ordered the amethyst turtle to sink into the rock formations of the burrow and excavate all the mineral deposits below.

At this time, the elemental queen responsible for vigilance suddenly said:

"Master, there is no danger here, can you let me leave here, and slaves don't like the environment here?"

Zhang Che turned her head and saw the elemental queen wrinkled slightly, looking at herself expectantly.

Yes, after all, she is a flame elf, in this extremely cold place, it must be very uncomfortable.

In order to prevent possible dangers before, she now found that there was no powerful alien beast in the burrow, and she was definitely reluctant to stay here.

"Okay, you go out and wait outside the cave, wait for the amethyst turtle to dig out the minerals below, and then I will go out to meet you."

Zhang Che naturally understood, nodded and agreed.

It will take a while for Amethyst to mine, and of course he will not force the Queen of Elements to accompany himself to wait here.

"Thank you!"

The element queen was relieved for a long time, said goodbye to Zhang Che, and quickly ran along the passage when she came.

After sending away the Queen of Elements, Zhang Che was not in a hurry, so she stood quietly waiting.

"Woowang!"

I don't know, Chiyan on the side saw the element queen leave, and couldn't help barking softly.

Well, as the royal beast of the flame system, Chiyan Cunning also extremely hates the environment here, reminding Zhang Che that he wants the owner to take it back to the sea to know the spirit.

"Well, you guys are really delicate, you can't afford this bitterness."

Zhang Che shook his head helplessly, and waved Chiyan back to recover the spirit.

Then, the entire cave fell into an endless darkness instantly.

"I'll go. I knew I wouldn't let the dog go back!"

The depression in Zhang Che's heart, although there is no danger here, but waiting alone in the dark, there is still something in my heart.

Forget it, wait outside the cave yourself.

Shaking his head, he gave an order to Amethyst Turtle, after he had dug into the ore, he went outside to the cave to join himself. Zhang Che also fumbled out along the road when he came.

Going back to the outside, the extremely cold feeling disappeared in an instant, so Zhang Che could not help but relax, and felt that the whole person was a lot more comfortable all at once.

He withdrew the beast armor of the beast on the surface, and chatted with the element queen without saying a word.

After waiting for nearly an hour, I saw the figure of the amethyst turtle digging out directly from the ground.

However, the amethyst turtle at this moment was obviously slightly embarrassed. The purple armor on the body surface was stained with a layer of pale frost.

"Are there any strange beasts in the rock formations of that cave?"

Zhang Che could not help but widen his eyes, and then saw the amethyst turtle open his mouth, a pile of minerals like white jade dumped out, and a half human height piled up in front of his eyes.

With the appearance of this pile of white jade-like minerals, the surrounding temperature suddenly dropped rapidly, as if directly coming to the cold winter.

"It's so intensely cold!"

Zhang Che finally understood why there was frost on the armor of the amethyst turtle's surface.

This pile of minerals is the culprit.

"This thing seems to be higher than the grade of Huoyuan Spar!"

Zhang Che's heart got excited immediately.

Anyway ~ lightnovelpub.net ~ This is an extremely rare and rare mineral, and its use is definitely not small.

"Since these minerals contain such a strong cold atmosphere, call you Xuanyin spar."

Zhang Che gave these minerals a name casually, and he waved them and put them into the cave storage space of the King of the Snake King.

What I didn't say, what is the role of this thing, you have to wait until you return to the northern capital, and let the technical staff of Laozhang people study it before you know it.

At this moment, a sudden change occurred in the spiritual consciousness.

On top of the colorful crystals, suddenly there is a strong colorful light shining down, completely covering the light group transformed by Xuansha Helong.

"Well, is it because the milky white spirits are not enough for the evolution of the Xuansha Heilong, so the colorful crystals are helping?"

Want to come and go first, only this is possible.

However, as a result, Zhang Che's heart was even more anticipating.

"Then, the next promotion of Xuansha Minglong is the nail-biting thing. I don't know if I will also improve the order at the same time."

It was gradually darkening.

Zhang Che simply returned to the cave, ready to camp here tonight.

Anyway, the pile of Xuanyin spar that emits extremely cold gas has been taken away, and it should not be too cold in the cave.

Sure enough, after entering the cave, although there is still a little coolness, it is no longer unbearable.

As a result, Zhang Che was preparing today's barbecue dinner, while waiting for Xuansha Halong to advance.

He did not wait too long, when the meat skewers inserted on the rock wall were roasted by the elemental queen with a strong aroma, the light group transformed by the Xuansha Hades in the spirit was finally broken into a butterfly .

This pet finally has the ability to fly at supersonic speed!
