Ahead, when the formation consumed the last trace of spiritual power, it finally couldn't support it anymore and disappeared between heaven and earth.

An open-air pit appeared in front of Ye Xiaoyu and Qin Yingying.

Around the crater, there were marks of tires running over everywhere.

"This..."

Qin Yingying looked at the scene in front of her, her little mouth was shocked and turned into an O self-shape, obviously very surprised.

"Yingying?"

Ye Xiaoyu glanced at Qin Yingying, the other party nodded tacitly, and then the two of them turned on the electronic devices they were carrying, and after He Qingke and the two teachers in Beicheng reported the news here, they jumped into the deep pit.

"Xiaoyu, it's so dark here, there won't be any old monsters living in the cave..."

Qin Yingying and Ye Xiaoyu walked together, the two of them carefully observed the surroundings, and kept walking towards the cave.

"Probably not, I've checked it with my divine sense, and it's empty. ”

As Ye Xiaoyu spoke, he bent down and observed the traces of the wheels on the ground.

"That's good... Look at the pitch black here... It's really crazy..."Qin Yingying has always disliked dark places, she is a person who is afraid of the dark, so even when she sleeps at night, she can only fall asleep with the light on.

But as a member of the Spirit Academy, she had a task at this time, because of her identity, she overcame her fear and chose to enter the dark hole with Ye Xiaoyu without hesitation.

"Xiaoyu, look what this is!"

Qin Yingying suddenly made a new discovery, and picked up a diamond-shaped stone from the ground, and the spiritual power contained in this stone was sensed by her.

"If I'm not mistaken, this should be a spirit stone with impure spiritual power, or a rough stone. ”

Ye Xiaoyu walked over, she looked at the spirit stone in the other party's hand, and said very seriously.

In the latest volume of "Popular Science Books", Ye Xiaoyu learned that the spirit stones circulating in the market at this stage are all spirit stones that have been artificially purified and have relatively strong spiritual power.

Before these spirit stones were refined by human industry, they were all rough stones mined from the ground.

There are many impurities in the original stone, and it can only be used if it is refined by industrial means and the pure spiritual power in the original stone is refined.

"Here... Is it a spiritual mine?"

At this time, Qin Yingying obviously figured it out, because it could be seen from the soil turned out of the cave that this place had obviously just been mined.

"That's right, I now suspect that the extraordinarily large hailstorm in Ebony Town may have something to do with the spirit mines here. Xiaoyu's IQ is still online, and after passing the analysis, he quickly came to his own conclusions.

"Xiaoyu, there's a rune paper here..."Qin Yingying made a new discovery.

"Don't touch it with your hands!!"

Ye Xiaoyu immediately reacted after seeing the rune paper, this thing is equivalent to a landmine, it will explode when it touches it!

But her reminder was obviously a step too late, because Qin Yingying had already used her hand to tear off the thunder guide talisman.

Boom Boom Boom...

As the lightning guide charm was detonated, more rune paper hidden in the black hole also exploded in a chain at this moment.

The explosion was so powerful that the entire ground where Ebony Town was located shook violently.

Qing Ke and Beicheng, the two teachers, were on their way to hurry after receiving the message from Xiaoyu, but when they heard the explosion from the target location, their hearts suddenly pounded.

"Beicheng, it seems to be an explosion from the light rain..."

Qing Ke looked obviously a little anxious, Ye Xiaoyu and Qin Yingying were her most proud students, but there must be no accidents!

"Don't worry, the two of them will be fine!"

At this time, Beicheng can only use words as much as possible to comfort his companions and let the other party not think about things on the bad side.

"Hmm!" Qingke nodded heavily, and then quickened the pace of the soles of his feet.

The scene of the explosion.

The previous black hole, due to a series of explosions at this time, the entire excavation channel was completely blocked.

With the arrival of the two teachers from Qingke and Beicheng, the students who went out on the mission also gathered here one after another.

"Beicheng, Xiaoyu and Yingying's communication equipment seem to have been completely lost..."

Qing Ke operated the high-tech combat equipment in his hand, and after he couldn't contact the two of them, he was completely panicked...

What's more, through her divine sense, she can't find the two of them...

When Beicheng heard this, he immediately fell silent, he was the teacher of the refining class, and at this time, he had already arranged for his students to dig the black hole.

He is a teacher, and he has a huge responsibility on his shoulders, so his students have to see people in life and corpses in death!

The crowd began to act.

Qing Ke was not idle, and also through his own magical powers, he was looking for Xiaoyu and the two.

The intense and efficient rescue work is being carried out in an orderly manner.

"Xiaoyu, don't have any accidents..."

Qing Ke was anxious in her heart, she didn't want her students to have an accident here.

She took the students out of school and of course brought them back to school safely!

"Let's stop for a moment!"

Beichen suddenly shouted and stopped the students from continuing to dig and rescue.

"What's wrong?"

Many people looked at Beicheng suspiciously, including Qing Ke himself.

"Thunderbolts. ”

Beichen looked at a thunderbolt talisman not far away, and said with a serious expression.

He is a teacher in the Spirit Academy, so he is not very unfamiliar with things like lightning charms.

Not only is this thing easy to carry, but it's also much more powerful than ordinary thermal weapons.

He had now guessed that so many lightning charms must have been used by criminals to destroy corpses and traces.

It's really ruthless!

"I'm coming!"

Qing Ke floated to Beicheng's side, only to see her hands quickly pinching the trick, and suddenly a gentle wind appeared, just blowing the thunder guide talisman on the ground.

When the lightning charm floated into the air, Qing Ke cast the spell again, detonating the lightning charm and successfully defusing the danger.

"How can there be so many lightning charms here? Presumably Xiaoyu and the others have accidentally detonated these things. ”

Qing Ke's face was very gloomy, and it could be judged from the explosion just now that an explosion of that scale just now would consume at least a thousand pieces of such rune paper.

You must know that at this stage on the market, each of these things is very expensive!

Criminals do not hesitate to spend such a heavy amount of blood, they must want to hide a big truth!

"Keep saving people!"

Beicheng did not rest, but directed everyone to continue digging, wanting to find Xiaoyu and Yingying quickly.

You two, you must hold on!

Promise me, hold on!
