When Dr. Zhu was ecstatically rummaging through the "waste products", Xu Shiji was also called away because of an extremely strange incident in the city.

"City Lord, City Lord, this is it, we were building the city wall just now, and those bricks and tiles suddenly became harder after being protected, and it seemed that the materials had changed, which frightened us all."

A crowd of people surrounded the battlements of the wall, and the bulge was completely distinguishable from the other masonry and even spreading, glowing black and blue, like the glow of metal.

Xu Shiji also frowned, reached out and knocked on it, making a thumping sound, he couldn't destroy it even with a little effort, you must know that the power just now was difficult for even B-level evolution warriors to parry, and this weird masonry actually withstood it.

As far as the eye could see, it was still spreading around, and it was about a meter in size, like a shield.

"Where did this stone come from?"

Xu Shiji asked with a frown.

"This is mined in the back mountain, have we found any difference from other stones!"

The men exchanged their heads and finally said.

"What about the color? There is nothing out of the ordeal. ”

He looked at the black and cyan patch, which seemed to have stopped spreading and reached about two meters.

"Color? It looks like it's cyan! It's really not quite the same as the other stones, but the color of those stones is darker. ”

"Quick, take me to the place where the stones were dug out."

Xu Shiji's breathing suddenly became short, because he thought of something, and suddenly a flash of inspiration.

A stone the size of a book would have strengthened the stone wall of about two meters as hard as armor, and if the whole city was covered with such stones, or if the city was built into a large castle or something.

How exhilarating it was to be able to defend the entire city with only a small number of men under the strong defense, and the thought of this made him feel like a grand plan was unfolding.

A group of several people hurriedly came to the back mountain, and the place where the bluestone was mined, the ravines were vertical and horizontal, and the gravel was everywhere, all of which were caused by a large amount of rough mining.

A few people walked like flying, how could the footsteps of the evolution warriors be blocked by a few small stones, and on the very complicated mountain road, they walked on the ground.

"City Lord, this is it, because the stones here are harder than those in other places, and the erosion is not so serious, so we have traveled a little longer to mine here."

Several people squatted down to find it, and the middle-aged man who had reported to Xu Shiji at the beginning continued, pointing to the pile of stones under his feet.

"This is it!"

Xu Shiji's eyes were like torches scanning the surrounding rocks.

But after searching for a long time, they didn't find any stones like that, and some of the big bluestones were also very light in color, and not as dark as that one.

"Didn't you say you found it here? Why not, it can't be just that stone! ”

Xu Shiji looked at a few people with a hint of scrutiny, and the things in front of him could be said to have poured cold water on his original enthusiasm, and the joy and sorrow calmed him down.

"How come, city lord, how dare we lie to you!"

"Yes, yes, we don't dare!"

The two of them also said in unison, a little sincerely afraid, afraid that Xu Shiji would mistakenly think that they had deceived him and be punished.

"What the hell is going on here?"

Xu Shiji carefully turned over the pile of stones, but still didn't find any clues.

Just when they were at a loss and ready to leave without any hope, the middle-aged man who came with them spoke up.

"No, there should be more than that, you see, this place should be caused by a landslide, and the pile of rocks piled up here, look, it should be the missing piece." The middle-aged man pointed halfway up the mountain.

Although the traces there are not obvious, a closer look can still show that there was indeed a part of the mountain that had fallen and defected in the past, and this is not a problem for the stone underneath.

"That's right! I really hit a dead end just now, you guys wait for me here, I'll go up and have a look. ”

Xu Shiji patted his forehead fiercely, his thinking had been imprisoned by Tianya Villa all along, and he had fallen into pattern thinking, if he hadn't been told by the middle-aged man just now, maybe he would really not have remembered it.

With that, his body trembled, and when he looked at it again, he was already flying into the air, flying halfway up the mountain.

As a peerless master-level powerhouse, of course he would not be stupid enough to climb the mountain, if it weren't for the ordinary evolution level of those guys just now, and they would lead the way, he wouldn't have taken so many unjust roads.

In just a few seconds, in the blink of an eye, he was flying to the landslide, where there should have been geological activity before, which caused a large landslide, and the pile of rocks did indeed slide down from here.

He floated in the air to inspect the wound of the mountain, inch by inch, and it was a careful one, as if he were looking at the woman he was infatuated with.

Because he knows how much impact this thing will have once it comes out, the butterfly effect may affect the change of human beings, such a strong wall, in the eyes of any person in power, is not a priceless existence, if this kind of stone has a large amount, what a great wealth.

He is not afraid that he will not be able to protect it, he knows the surrounding future cities, there are no stronger than himself, there are almost a few, most of them are much weaker than Tianya Mountain Villa.

When the mecha legion is developed, no one in this future city should have the strength to compete with Tianya Villa, Jun Invincible was repelled by his sister, and I am afraid that he will not dare to invade rashly in a short time.

He is now in power, he understands the thoughts of this class, and the loss this time is so huge, even the person who has no power for a while is afraid that he will be very distressed.

At least if it had happened to him, he might not have eaten for three days.

Thinking of this, his breathing became rapid again, and he was very excited.

Those eyes were like the sharp edge of a divine eagle, and he swept over but did not find the bluestone he imagined, which made him very disappointed.

I think today's luck is terrible.

"How could it not be! This kind of thing shouldn't be just one piece! ”

Of course, Xu Shiji wouldn't believe that there was that stone in such a big mountain, it should be that he didn't find it, otherwise there was only this one where it came from, it must have been an ore vein growing.

Ore veins!

That's right, just do it.

He instructed the people below to stay away, and he was to forcibly smash the surface of this mountain, and there must be a vein of such a stone here, which is inevitable, there is no love for no reason, there is no hatred for no reason, and there is no stone for no reason.

Unless it's the second Monkey King.

"Let's all go farther, I'm going to start, don't let the gravel hurt you by mistake for a while."

Xu Shiji rolled off his sleeves, rude and manly.

A few people hurriedly left, and they probably guessed what Xu Shiji planned to do.

"Tomahawk Battle!"

Xu Shiji's hand was shaking, and his axe appeared in the ground, as if it was magic.

"Slash!"

As soon as the words fell, an invisible sword qi broke through the air, making a piercing sound that resounded through the valley.

Boom!

Bones! Bones!

With the fall of the tomahawk's blow, the cliff was cut out of a ravine that stretched for a hundred meters, several meters deep, extremely destructive, plus his strength at the same level is super strong, just one kick away from breaking through to the SS level, and now with the tomahawk to improve the strength, in fact, the blow just now is not worse than the blow of the SS-level powerhouse.

"Boom!"

Countless boulders rolled down, and the few people below were a little away again, and the dust filled the air, covering the realization, and Xu Shiji waited for the moment to disperse before starting to search.

The emperor lives up to his wishes!

Just as he had found a third of the way, he made a discovery, a dark cyan stone reflected in his eyes.

Xu Shiji's eyes suddenly lit up, and he hurriedly fell there.

If you look closely, the black and blue stone is actually a kind of jade, because the color is too dark to look like metal, in fact, if the light hits it, you will see a crystal clear jade.

He hadn't heard of this stone, and he hadn't seen it before, and it should have been mutated due to the coming of the end times, which was really breathtaking.

With a wave of his hand, it was like a hurricane sweeping through, and the rubble on the surface was swept away.

Leaving a bare mountain, the kind of stone is actually distributed in large areas, especially in deeper places, more often.

How many are there, exactly?

He looked at the mountain under his feet, as if he were looking at a mountain of gold.

Volleyed into the air again, the giant axe swung, and once again destroyed part of the mountain, which was still black and blue, and the deeper it was, the more it was.

He now figured out why there was no gravel in the pile of rubble underneath, because where it was really badly eroded by the wind, it was all waste rock, and it covered the surface, and the landslide fell down to a layer of skin on the surface, and the actual treasure was hidden behind this layer of skin.

Xu Shiji was overjoyed, what a big mountain this is, it won't all be made of this kind of stone, it's too terrifying.

However, the more he became, the happier he became. Like, who would be afraid of money.

He remembered that before the end of the world, the boss of a certain Baba company said that if he was given another chance, he would never create a certain company, which was pure nonsense.

I am afraid that he didn't think about the consequences when he said it himself, or pretended to be limitless.

Xu Shiji shook his head and threw this idea out quickly, he didn't know why he suddenly thought of this, probably because he wasn't very interested in that person, or his words made him very "helpless"!

"Come here!"

Xu Shiji flew to the ground and beckoned to several people.

He whispered a few words in the ears of several people, and several of them left in a hurry.

He stayed here, staring intently.

The wind was gusting in the valley, but he didn't feel the cold, not because he had a strong body, but because of the excitement in his heart, his body was hot and resisted the invasion of the cold.

It's a strange force that no one can explain.

After a while, the men returned.

It was followed by a mechanical team, forklifts, earth-pulling trucks, and a large number of young and strong laborers.

Mining rough stones, right now, now is the time to strengthen the city walls, and these stones come in handy.
