Boom boom boom.

The sudden earthquake startled the workers in the cave. They thought the cave was going to collapse, so they rushed out.

Tang Heng, the second-class expert, appeared outside the cave in an instant, shocked and angry, "What's going on?"

The other two arrived shortly afterwards.

"I don't know, was there an earthquake?" Tang Zongping, the weakest one, asked in surprise.

"Don't talk nonsense, how could there be an earthquake in the mountain and sea disaster area!" Tang Yu, who had the third-class cultivation level, scolded.

There hasn't been an earthquake here in hundreds of years. If there was an earthquake, it wouldn't have happened during this time period.

Tang Heng immediately stood on a high ground and finally saw the cause of the earthquake.

It is hard not to see it. The red wavy patterns and hundreds of red-haired beasts moving in unison are enough to shock anyone who sees it for the first time. Even Tang Zongping, who had only been there for less than half a month, was shocked.

"What is this? Why are there so many mutant creatures?"

It was the first time he saw such a spectacular scene and he was deeply shocked.

"The red-haired beasts are the largest species of mutant creatures in the mountain and sea disaster area. They should have lived on the next hill. Why did they appear here?" Tang Heng said with a cold face.

Tang Yu took a closer look and said, "It's their leader, and it seems to be chasing a few mutant creatures."

Many social creatures have a leader. The leader's every move has an impact on his subordinates, and it can be said that a single move can affect the entire body. Now the problem obviously lies with the leader of the red-haired beast.

"The eyes of the red-haired beast leader are red." He suddenly took a breath.

When the red-haired beast's eyes turn red, it means that it has entered a manic phase. It is very difficult to calm a red-haired beast in a manic phase.

While they were talking, the group of red-haired beasts had already rushed into the area they had planned.

The seven workers were very weak. When they suddenly saw a group of terrifying red-haired beasts rushing towards them, they were immediately frightened and ran around with their heads in their hands. After a while, they ran away. One of them was hit by the horn of a red-haired beast, and his abdomen was immediately covered with blood.

Tang Heng frowned and said, "You guys go down and rescue them. I'll subdue the leader of the red-haired beasts. Be careful and don't let them rush into the cave."

"Yes." The two of them responded and rushed down immediately.

If there were more people, perhaps the situation could be controlled, but there were only three of them, and the workers would only cause trouble, so it was inevitable that some fish would slip through the net.

Without noticing, several red-haired beasts were pushed to the front of the cave.

"Zong Ping, go stop them. Guard the entrance of the cave and don't let them rush in. Also, don't see blood, otherwise they will go crazy." Tang Yu immediately shouted to the young man upon seeing this.

"good."

After Tang Zongping finished speaking, he rushed forward. A red-haired beast was right in front of him, and its body suddenly exploded.

Blood and organs splattered everywhere, and Tang Zongping, who was closest to them, was inevitably covered in them. The smell of blood instantly spread all around, and the red-haired beasts nearby smelled the blood, their eyes instantly turned red, and they stared at him in horror.

Tang Yu thought it was Tang Zongping who did it, but he lost his temper just after he finished speaking, and said angrily: "Damn it!"

The mad red-haired beast's combat power is at least doubled.

Tang Zongping's strength was only at the fourth level, so he could handle two or three red-haired beasts that were not crazy at the same time. But now there were five or six of them, and they were all crazy, so he was immediately in a panic.

"Uncle Yu, I can't stand it anymore."

The young man's face turned pale, and he flew out spitting blood as soon as he finished speaking. The entrance to the cave was instantly knocked open by the red-haired beast.

In a place where no one was paying attention, Gao Han, who was hiding on a red-haired beast, entered the cave.

Ignoring the red-haired beast, he quickly rushed into the depths of the cave.

In addition to the naturally formed space inside the cave, there is also a newly dug stone cave with some daily necessities placed inside. Those people probably slept here at night.

In addition to this place, there is a stone house next door with a small black door on it. If he hadn't had sharp eyes, he might have missed it.

In a hurry, they were able to lock the small door, so the things inside must be extraordinary.

Gao Han broke the lock of the small door without hesitation. As soon as the door opened, the light inside rushed out. The silver lizard in his arms had already rushed in impatiently.

The space inside the door is not big, with a table and some instruments, and the corner is filled with sparkling spirit stones.

Some of these spirit stones were still covered in dirt. There were large and small ones, but the largest one was no bigger than an adult man's fist.

Knowing the coldness of the Lingshi Mine, I was certain of one thing after seeing this scene.

It seems that this spiritual stone mine is really not big.

No wonder the Tang family only hired seven workers to mine. If there were more people, the efficiency might not be improved much, but it would increase the risk of exposing the existence of the spirit stone mine.

If it was a large spirit stone mine, the largest size of these irregular spirit stones would be larger than an adult's fist, and should be at least as big as a head.

These instruments should be used by them to refine irregular spirit stone ores.

When some spirit stone mines are just dug out, they contain impurities and are not pure enough. If they are absorbed directly, the impurities will be absorbed into the body, which is not conducive to later cultivation. Therefore, after the spirit stone mines are dug out, they need to be refined with instruments, and the final form is spirit beads.

The Tang family concentrated the excavated spiritual stone ore in this stone room, cleaning and refining it at the same time.

Gao Han looked around but didn't see the refined spirit beads. There was an empty box next to it. The refined spirit beads should have been put away by them.

The silver lizard picked up a spirit stone that was half its size. Its tongue was hanging out and saliva was all over the floor. It opened its mouth to take a bite, but its claws were empty.

The spiritual stone mine was taken away by Gao Han. "Now is not the time to eat it. I will give it to you when I get home."

After saying that, he put the spirit stone ore in the corner into the Yayoi Ring.

There were also a few spirit stone ores in the bucket at the door. They were covered with more dirt and looked a bit black, as if they contained more impurities. He did not miss any of them and accepted them one by one with a smile.

After sweeping all the spirit stone mines, Gao Han carried the somewhat emotional and pouting silver spirit lizard out, and suddenly turned back to look at the instruments inside.

After getting the bargain, the man and the beast did not go inside again.

Gao Han returned the same way he came. Less than five minutes had passed since he went in, and the battle outside was not only not over, but was getting more and more intense.

After Tang Zongping was besieged by several red-haired beasts, Tang Yu killed a few more red-haired beasts in order to save him. As a result, the smell of blood became stronger and stronger, and more and more mad red-haired beasts became involved, and finally the situation got out of control.

In order to solve this trouble, Tang Heng showed his power directly, killed the leader of the red-haired beast, and then swept all the way.

The other red-haired beasts were scattered by him, and the red-haired beasts that lost their leader were completely in chaos, and the herd scattered in all directions.

Gao Han took the opportunity to follow a red-haired beast out and forced it to run to the periphery.

Until I could no longer see those people from the Tang family.

After letting go of the red-haired beast, he did not stop and headed straight for the exit.

There are only a few days left before the end of the training.

…

More than half an hour later, Tang Heng and Tang Yu finally controlled the mad red-haired beasts. Most of the red-haired beasts ran away, and only a few were left nearby, which could no longer pose a threat to them.

Tang Zongping was slightly injured, three workers died, and the other four would have died if they had not dodged quickly.

Looking at the messy cave entrance, Tang Heng's face was gloomy and terrifying.

After this fight, the crisis of the red-haired beast was resolved, but these corpses and the strong smell of blood in the air could not be hidden. Other mutant creatures nearby would quickly come over as soon as they smelled the blood.

As for the several mutant creatures being chased by the red-haired beast, they had long since disappeared.

"Tang Yu, you and Zong Ping deal with the corpses of these red-haired beasts and try to get rid of the bloody smell. I'll go in and take a look." After saying this, Tang Heng turned and went into the cave.

After a while, Tang Heng's roar of shock and anger was heard from the cave.

"Damn it, who is it, who did it?!"

Tang Yu and Tang Zongping were startled and ran over immediately. Seeing Tang Heng standing in front of the stone house with an extremely angry expression, they both had a bad premonition.

Could it be... that there is something wrong with the spirit stones in the stone room?

The two of them walked quickly to the door, only to see an empty stone room. Not only were the spiritual stones in the corner gone, but even the priceless instruments had been moved away. Their heads buzzed and their eyes widened in disbelief.

Tang Zongping stammered, "How could this happen? Could it be that someone deliberately lured those red-haired beasts here?"

Tang Yu gritted his teeth. He finally understood. "It's not a possibility, but a certainty. The red-haired beast that suddenly exploded was the work of the other party."

Tang Zongping still couldn't figure it out, "But how did they get in right under our noses?"

Tang Heng's face was as gloomy as water. "It was those red-haired beasts that rushed into the cave. He must have hidden on one of them, taking advantage of the chaotic situation to sneak through, and then used the same method to escape from the cave."

Tang Yu made a prompt decision, "This person just left not long ago, he must not have gone far, let's go after him now!"

"Chase, how to chase, do you know who he is? Do you know which direction he went, and do you know that he must be alone?"

Tang Heng asked three questions in a row like a barrage of artillery fire, making Tang Yu's face become more and more ugly because he couldn't answer any of them.

How can they chase if they don’t know anything?

Tang Zongping said unwillingly: "Are we going to have to bear this loss? Those are spirit stones that can be refined into spirit beads. With so many spirit stones, we can refine a lot of spirit beads."

Naturally, no one present was willing to accept this.

It is difficult to refine spirit stone ore, otherwise they would have refined them all into spirit beads long ago, and the stolen spirit stones were the bulk of them.

If it weren't for this accident, the remaining spirit stone mines would have been mined in two days.

This mine is just as Gao Han guessed, it is just a small mine. Because it is a small mine, the purity is not high, which is why it is difficult to refine. However, it can also refine a lot of spirit beads, which will be the foundation of the Tang family.

With these spirit beads, the Tang family will be able to cultivate more powerful people. In time, it will not be difficult to become the top family in the imperial capital.

Tang Heng closed his eyes, then opened them again, a fierce look burst out, "That person must still be in the disaster area, block the exit of the disaster area, from today on, only people are allowed in, not out, everyone who goes out must be searched!"

"But the people in the disaster area are not only the young people of the Tang family who are training, but also spirit refiners from other forces. Will this offend them? Moreover, we discovered that this spirit stone mine is a secret of the Tang family. If we do this, will it be leaked out?" Tang Yu was full of worries.

Tang Heng's face was gloomy. "That person's behavior is sneaky. I'm afraid he's not from a powerful position. If he is, there's no need to worry about the consequences. We can discuss it later if something happens. As for the body search, just find an excuse to get away with it. Even if they want to suspect him, they have no evidence!"

Tang Yu thought about it and realized that this was indeed the only way.

The matter of the spirit stone mine is too important. We must not let the other party leave the disaster area, otherwise, there will be no hope of getting those spirit stones back.

"If I knew who it was, I would skin him alive and pull out his tendons!" Tang Zongping gnashed with hatred.

Not only him, if they knew it was Gao Han, the entire Tang family would probably want to skin him alive.

The spiritual stones he stole were not only spiritual beads for cultivation, but also the glorious future of the Tang family.
