There is no doubt that that is the location of the Cold Sky Nail, and the power fluctuations coming from there are very similar to the thing on the top of the snow mountain.

"Ah? Are you on your way again?"

Before he could take a few breaths, Beidou shook the corners of his eyes.

If Ying was spending his elemental power as a pilot before, then as a passenger, Beidou had to tighten his body all the time in the air, which consumed several times more energy than Ying.

"What? Are our Captain Beidou tired? If you want, you can take a rest here."

Seeing the playful look on the young man's face, Beidou complained in his heart.

This brat has a really bad character.

"Ah ah ah, let's go, let's go, I'm not that delicate yet."

Beidou frowned and waved his hands indifferently, looking like he was giving up on himself.

Having said this, she looked at Shen He beside her a little strangely, but found that there was no fluctuation on his face and his breathing was very steady.

This is strange. As a 'passenger' in the air, this guy doesn't look tired at all.

You must know that before, he had crossed nearly half of the rocky abyss, and he was still hanging in the sky.

Is it possible that the physical fitness of immortal disciples is much stronger than that of ordinary people? It seems not.

However, what Beidou doesn't know is that the reason why she spends so much energy is that she needs to constantly tighten her body in mid-air and be ready to deal with danger at any time, while Shen He directly puts his entire safety in the hands of the boy holding her, completely

I didn't exert any effort, so naturally I'm not that tired now.

Just when Beidou was still wondering about this matter, several people stepped across the passage in front of them and arrived at the depths of the cave.

Blue light filled the entire underground, and a huge nail with the texture of a night stone floated in the air. It was the Nail of Hantian that Bai Qiyun had once met.

It's just that this nail looks more complete than the one on the snowy mountain, but it is surrounded by black and red mist.

That kind of fog gave Bai Qiyun a very bad feeling, just like the mud he had seen before.

The mist was like chains, locking the Cold Sky Nail in the air, preventing its own power from dissipating at all.

"Is it possible..."

Seeing this scene in front of him, Bai Qiyun had a conjecture in his mind.

This Hantian Nail seems to have different functions from the one on the Snow Mountain. The Nail on the Snow Mountain directly caused the environmental changes in the Snow Mountain, while the one here is suppressing the generation of that kind of filth, which seems to be beneficial.

Human things.

"In other words, if those things are purified, the underground matter will be over, right?"

After telling everyone his thoughts, Beidou drew the black rock sword behind him, looking eager to try.

If it weren't for the fact that everyone was still quite far away from Hantian Nail, Bai Qiyun would have been afraid that this guy would rush directly towards him.

Looking around, Ying's duck-oval face swayed back and forth, as if she was trying to determine the source of the mist.

After a while, the girl's voice rang in everyone's ears.

"Having said that, how to purify those things is a question. Are the Lumen Stones in our hands really enough?"

You must know that the Lumen Stone is completely useless against the sludge under the hanging city they have seen before.

And here is the source of the mutation. Will something like scraps really work for a being of this level?

However, Bai Qiyun is not very worried about these. In addition to the Lumen Stone, he has his own support.

At worst, just use the power of the stars to crush them head-on.

But before that, I carefully discovered something unusual at the roots of those 'mist chains'.

From a distance, it looked like there was something buried underneath the piles of lumps that looked like they were wrapped in mud, but it was really hard to see clearly from this distance.

Without saying anything else, Ying took advantage of the wind and flew to one of the places.

Sure enough, there was a very delicate-looking instrument placed under the mud.

She activated the power of the Luminous Stone in her hand and cleared away all the mud around her.

But after the sludge wrapping the instrument disappeared, the 'mist chain' connected to the Cold Sky Nail did not disappear, and was still hanging brightly in the air.

Seeing this, his throat moved slightly.

Could it be that she guessed wrong?

But before she could take any action, she suddenly felt that the power of the Lumen Stone in her hand was constantly draining away, and the destination was the device with unknown meaning in front of her.

Every time the Lumen Stone loses power, the device in front of it lights up by one point.

Soon, the power in the Lumen Stone was exhausted and turned into a handful of dust and disappeared into the world. However, the device was obviously not filled up yet and was still dim.

"Come here quickly!"

Facing the girl's gaze, Bai Qiyun and others took out their own lumen stones under Ying's persuasion.

Sure enough, the moment they took it out, the lumen stones in their hands began to send power towards the device.

In a few moments, the device was completely filled, and a crystal blue light lit up in the dark cave. If you like Genshin Impact, the Spear is Still Still in your collection, please collect: (https://www.bajiewx.com) Genshin Impact, the Spear is Still Still Searching Novel Network Update Speed
