Jiang Ning's eyes became extremely sharp, and he directly volleyed into the air, and a punch slammed out.

The blue dragon pierced the air, containing furious energy, and rushed straight towards the Iron Devouring Beast.

The Iron Devouring Beast was originally the end of the strong crossbow, and after Jiang Ning cast a Heavy Heavenly Xuan Seal, his strength increased greatly, and this blow hit the Iron Devouring Beast's chest, directly piercing it.

The Iron Eater's giant claws were still held high, but they were powerless to swing them at this point, and finally fell to the ground with a bang.

Jiang Ning stepped forward and put his hand on the Iron Devouring Beast's body, feeling that it had no breath at all, before he relieved himself and lifted the Heavenly Xuan Seal.

Jiang Ning then condensed the spiritual power between his fingers to form a sharp knife, and then gently slashed it at the belly of the Iron Devouring Beast.

Between his fingers, an arm-sized piece of copper ore appeared in front of him, and the feeling was extremely familiar.

"Red Flame Iron Mine!"

Jiang Ning exclaimed in surprise, he didn't expect this Iron Devouring Beast to give birth to such a precious ore, which was a high-grade material for making spiritual treasures.

Jiang Ning stretched out his hand and took out the Chiyan Xuaniron Mine, and I could feel the spiritual power contained in it flowing on the surface of the ore in my hand.

"What a treasure. ”

Jiang Ning sighed, originally just wanted to find out, but he didn't expect to get such a good thing unexpectedly.

After wrapping the Chiyan Xuaniron Ore in a cloth, Jiang Ning was about to turn around and leave, but after thinking about it, he turned his head and glanced at the Iron Devouring Beast.

"Alas, since this is your domain, rest here in peace, and no one will disturb you again. ”

Jiang Ning sighed helplessly, this Xuanbing Black Iron Mine Cave must have been discovered by the Lu family, and then they sent someone to mine it, and in the process of mining, they found the Iron Devouring Beast and imprisoned it.

Thinking of this, Jiang Ning suddenly understood.

This Lu family must have discovered the secret of the Iron Devouring Beast, and knew that feeding the Iron Devouring Beast could make it produce more pure ore in its body, otherwise it would be impossible for the Lu family to raise such a hidden danger.

"Could it be that the Jin Chan knife of the first generation of the Lu family head was forged from the Chiyan Xuaniron ore?"

Thinking of this, Jiang Ning showed an excited expression on his face, his palms clenched into fists, and he looked like he was bound to win: "This knife, I'm going to decide!"

After Jiang Ning finished speaking, he turned around and suddenly swung out a palm, and the corpse of the Iron Devouring Beast was blown backwards and slid directly back into the hole.

Due to the drop of this cave of several tens of meters, the corpse of the Iron Devouring Beast smashed down to the bottom of the cave, forming a strong concussion, and the entire mine trembled.

"Not good. ”

Jiang Ning frowned, seeing that there was a crack on the rock wall, which he had never seen before.

"Run, this mine is going to collapse. ”

Jiang Ning shouted at the miners, and then quickly pulled them towards the secret door.

At this time, there was a mess outside, and the guards were completely unguarded after they fled, but these miners were just chattering and arguing inside the miners, and no one dared to run outside.

Because they were all already afraid, the rule that they couldn't leave here was so deep in their bones that they didn't dare to run out even without the guards' watch.

After Jiang Ning passed, he found Lao Tian and Zhang Yan, and when he saw that they were fine, Jiang Ning was relieved.

"Let's go, this place is about to collapse, we need to get out of here. Jiang Ning said, and then found Lao Zhang's figure in the crowd.

"Brother Zhang, hurry up and organize everyone to go out, this mine is about to collapse, you must hurry. ”

"What the hell is going on? Can I get out? What if the guards come back?"

Lao Zhang looked at Jiang Ning suspiciously, although he had completed the 10-year period, it also meant that he had been in the mine for 10 years, and the rules in the mine had been deeply imprinted in his heart.

"The guards won't come back, Elder Deng is dead, the mine is about to collapse, hurry up and organize everyone to evacuate!"

Jiang Ning grabbed Lao Zhang's collar and yelled at him loudly, then pointed to the rock wall next to him.

"Look, this rift is getting more and more, it's too late if you don't leave, are you going to kill everyone?"

Jiang Ning's words were like a thunderbolt from the sky, looking at the rapidly expanding cracks on the rock wall, Lao Zhang also reflected, and then quickly found the captains of the other teams, and then began to organize the evacuation of the crowd.

The reason why I want to ask Lao Zhang for help is because he has prestige in the mine, and everyone else will listen to him, if Jiang Ning is directly a big man and tells everyone that the mine is going to collapse, it will inevitably cause panic.

In the event of a larger riot, the scene will become uncontrollable, and everyone will rush to the top, not only will the speed of going out be slower, but there will even be stampedes, causing unnecessary casualties.

Under the organization of several captains, the personnel quickly evacuated outside, and the guards guarding the door outside had also run away, losing the deterrence of Elder Deng, and no one was willing to give their lives to the Lu family.

Just when the crowd was almost out, Jiang Ning was about to leave, but saw Lao Zhang suddenly walking back, and he actually returned to the mine.

At this time, it was already the last few people, and the people inside had been evacuated, and the entire mine had become fragile, with stones constantly falling, and there was a danger of collapsing at any time.

"Grass, this damn thing. ”

Jiang Ning gritted his teeth, rushed quickly to the mine, and came to Lao Zhang's side as fast as he could.

He knew what Lao Zhang was doing in there, some of the ore that Lao Zhang hid last time, if it collapsed, the ore would not be found, so when Jiang Ning saw Lao Zhang enter, he knew that Lao Zhang wanted to take out the ore before the mine collapsed.

"You don't want to die, is this thing so important?" Jiang Ning grabbed Lao Zhang's collar and stared at him fiercely.

"You let go of me, it's my thing, I've worked here for so many years, just pointing to this thing for some money. Lao Zhang struggled and struggled to reach for the ore, but was caught by Jiang Ning, and his hand was not long enough to reach it at all.

"You really want money and don't want to die, you haven't thought about it, what if you take this ore, what if you can't get out and are buried in it?"

Jiang Ning reprimanded him, then stretched out his hand to take the ore in his hand.

"Let's go!"

The rockfalls in this mine cave became more and more numerous, and Jiang Ning grabbed Lao Zhang and brought him out as fast as he could.

"Something, my thing, give it to me, give it to me. ”

Lao Zhang got up from the ground and quickly came to Jiang Ning's side.

Looking at Lao Zhang like this, Jiang Ning shook his head helplessly, and then handed the piece of ore to him.

Lao Zhang held the ore in his hand, his hands trembled, and he showed a happy smile.

Boom! Boom!

At this moment, the mine behind him collapsed in an instant.

Due to the Lu family's over-exploitation of the mine, this collapse caused a chain reaction, and a small half of the southern side of the entire Yannan Mountain slid down with a bang, and this scene looked very shocking.
