"Sister Gong, what does this man mean? It was still menacing just now, but it ran away in a blink of an eye! ”

“…… I didn't understand either, I'll ask Sister Chu later. Alright, don't stand here, do whatever you want. ”

Gong Xiaoran pondered for a long time and decided to send a flying letter to Chu Yu first.

It's very rare that Chu Yu didn't return in seconds, which is not the same as before.

Busy?

Gong Xiaoran put this aside in advance and began to think about the contact with the Steel Dome Company.

——

Chu Yu is indeed busy, and she is at a critical moment of breakthrough.

In the No. 1 shaft of the Beishan Mine, the wind is howling and the sound is like a ghost's cry.

Chu Yu sat in the place where he used to retreat with his senior sister, and bursts of yin qi ingested the dantian qi sea under the operation of the spirit technique.

The depleted spiritual power in her body had been replenished, and her goal now was to reach the next small realm as soon as possible.

Then she sighed, and the exercise came to an abrupt end.

Reasons for sighing...... It is that her realm can now be said to be the peak of the three-level Qi refining half-step Great Perfection, in short, it is almost a loss.

Qi refining is a process of accumulation, the higher the realm, the more spiritual energy is needed, and in the end, it will come naturally.

"Too little!"

This branch vein was deep enough, but the yin qi contained in it seemed to be only enough for her to cultivate to the third level of qi refining.

It's okay to stay here all the time, but it takes more time, and the most precious thing for Chu Yu now is time, and it is impossible to waste it here.

It occurred to her that the blocked main road, and perhaps she should go there and take a look.

Just do it, Chu Yu got up and patted the dust on his clothes, and walked in the direction of the main road while replying to Feixin.

"Vacuum cleaner-like instrument ......"

Gong Xiaoran speculated that it was used to detect traces of spells, and Chu Yu was very similar to what she thought.

But that's just speculation...... On this trip, in addition to trying to break through, Chu Yu has two other places to go:

One is the base of the security team located in the mountains in the north, and the other is the center of Tianhai City, the Qihang Building of the Yali Company.

She didn't want to go through it a second time. Instead of passively hiding, it is better to take the initiative to explore the reality of Yali Company.

Don't pop out of a black mirror one day and beat yourself to death, even if you die, you have to die to understand!

As for that Shen Yu, Chu Yu was sure that this person must have discovered the identity of a psionic person, but he didn't do it for some reasons.

"I see. Beware of the one surnamed Shen, Maoyantang's eyeliner in the city has also developed more. Feel free to report to me if you have something......"

Chu Yu typed words as he advanced, and it didn't take long to reach the main road blocked by rocks.

Is it really impossible to get through?

She put away her phone and carefully examined the crevices of the rocks; I joked with my senior sister that she was going to blow it up, but she didn't dare.

After taking a closer look, Chu Yu found something wrong.

There are radial cracks in the stone wall above, which are obviously not naturally formed.

This place is deliberately blocked by stones blown out of explosives!

This discovery surprised her, who had thought that it had been blocked because of a landslide, but now it seems that this is not the case.

What happened here?

A main mine can bring hundreds or thousands of yuan stones to the mine every day, and the chief of the company in charge of the mine should also know about this.

What made them give up such a big profit, but also give up this mining road?

However, if this is the case, it means that not all of them are blocked......

Chu Yu's eyes rolled, and he already had a plan in his heart. The spell was cast, and he walked directly through the wall technique.

After a few seconds of darkness, it suddenly became clear that the long main road stretched towards the bottom of the vein.

Sure enough, there was a road ahead.

Chu Yu walked inside with brisk steps.

Although she couldn't see her fingers, Chu Yu no longer needed a flashlight now, and with her cultivation, she could see at night, and everything in the cave could be easily seen.

The railroad tracks, which had fallen into disrepair, were rusty, and the wooden sleepers smelled of decay, mixed with the humid air of the cave.

Chu Yu walked for a long time, and faintly noticed that something was wrong.

It seems too quiet.

In the first half of the unplugged period, she could occasionally see animals such as rats and bats, but there seemed to be nothing in them, and she couldn't hear any sound.

Only the sound of her footsteps echoed in the vast cavern.

Moreover, this No. 1 mine is inevitably too deep, and No. 4, which she has been to before, does not seem to be so long.

Chu Yu took out his mobile phone and took a look, and sure enough, there was no signal.

It's kind of weird......

She was a little vigilant in her heart, but she had no intention of retreating.

After cultivating for so many years, what danger has she never been to? If this is scared away, it will make the disciples laugh at it.

And then something even weirder came.

Not far away, she saw a skeleton.

Only the skeleton remained, and the clothes on his body were also tattered, judging by the slave ring that was still intact at the neck position and the condition of the clothes, it should be a dead mine slave.

He maintained a posture of crawling outward, leaning on the ground, one arm stretched forward, as if telling the unwillingness of death.

If it was just an ordinary corpse, Chu Yu didn't care too much, the problem was that he was not ordinary.

She saw that the upper half of the skeleton was intact, but the lower half of the body was gone, the place of the pelvis had been broken, and the gray bone was shattered to the ground.

Cut off? No, look at the hideous cracks on the bones, it should have been bitten alive by some creature!

Chu Yu was vigilant, and moved forward with his breath, trying not to make too much noise.

The further you go, the more bones there are.

And none of them looked like people, some had no heads, some had no legs, some had no arms, and some had only one piece of clothing left.

Their mining pickaxes and sacks were scattered all over the ground, and Chu Yu saw that some of the bags still contained a lot of Yuan Mother Stones.

Monsters?

After coming to the Celestial Society, it seems that she has never encountered a creature such as a demon beast, and she still thinks that there is no one on the Lingyuan Star.

But the bones all over the ground reminded Chu Yu that there was not only one here, but it was probably a big guy.

She now understood why the mine was sealed.

Chu Yu continued to move forward, the railroad tracks had long been broken, and the cave became narrow.

More and more bones remained, piled up haphazardly.

If ordinary people saw this scene, they would have been scared and fainted, but Chu Yu didn't.

She, on the contrary, was a little happy.

That's right, happy.

Because there is a lot of yin here...... It's just right for her to practice.

She closed her eyes and felt the yin qi here, and the intensity was more than ten times higher than that of the previous retreat!

Boom ...... It doesn't matter what kind of monster you are, obediently make room for this ancestor!

Chu Yu showed a signature smile on his face, but before the smile was over, he saw a black shadow, which suddenly flashed out from the corner and pounced in front of her!
