The hole was only the size of two fists, and the two of them looked a little blurry, and there was a golden-red light underneath, and they could only see about a meter down, and there was nothing within a meter range.

"What the hell is underneath this, and how deep is it?" Tang Xiao seemed to say to himself.

I don't know how deep it is, and I can't see it.

"Young Master, this is like the energy of an energy crystal!" Iron Hand said.

"I feel it, this energy is purer than the energy spar, I don't know how many times. Tang Xiao nodded, he naturally felt it.

"If you want to know what's down there, you have to go down and see, you can't see anything here. ”

"Then go down, wait, I'll widen the hole ......"

After Tang Xiao finished speaking, he continued to put his hands on the two fist-sized holes.

Iron Hand stepped aside and began to wait patiently.

......

"Young master, I'll go down first, if I don't give you a signal, you won't go down, it's dangerous!" Tie Shou wanted to go down first, but was stopped by Tang Xiao.

"I'd better go down first!"

"I can't help it, young master, you are now the leader of the entire Savior Alliance, in case there is a burden of the entire alliance with three long and two short, who will resist?" Iron Hand jumped down directly after speaking.

Tang Xiao was a little moved, Tie Shou said so much, in fact, he was still afraid that something would happen directly, and as for saying so many reasons, it was just a cover-up.

It took about a minute or so for Iron Hand to hear the sound of something heavy falling on the ground.

Listening to the sound of the ground, it is definitely not moving forward, and if it is such a big hole, it will be difficult to come up later.

"Prepare ......"

Tang Xiao thought about taking out a large coil of rope from the storage space, one part was tied to the outside, and the other end was thrown down. "Iron Hand?"

Tang Xiao shouted at the hole, but there was only an echo of his own, not the slightest sound of an iron hand.

Tang Xiao couldn't help but be a little worried. "Iron Hand, what's next?"

Still no one responded.

At this moment, Tang Xiao was even more panicked. "Don't get an accident!"

Tang Xiao thought to himself and yelled towards the entrance of the cave.

"Young master, come down, it's okay, it's so shocking and stunned!" Iron Hand's voice came from the cave.

At this moment, Tang Xiao breathed a sigh of relief. "You kid waited for me, you scared me to death!"

Saying that, Tang Xiao jumped down.

When I jumped down, I felt the energy around me suddenly come alive, and it was like a large stone stalactite cave.

Tang Xiao looked at everything around him, he now knew why the iron hand didn't speak for a long time after it fell, and he was really shocked.

Peng......

landed on the ground, and the iron hand hurriedly came up. "Young Master, are these all high-grade materials?"

Iron pointed to the materials all over the ground, these stones have a hint of red in the gold, and they look crystal clear like jade. "This ...... What is it?"

Tang Xiao picked up a piece on the ground and held it in his hand and looked at it, this stone was crystal clear, if it was all gold, it would definitely be an energy crystal, but now this gold was mixed with a kind of red.

"Isn't it?

Tang Xiao began to let the system scan with a guess.

While the ingots were scanning, the two of them circled around, this is simply the underground of the entire Dark Duchy, there are such gold and yellow stones everywhere, and lava steel in the center of the earth is also everywhere.

These two materials actually grew together, Tang Xiao didn't know what was going on. "It's a vein here......"

At this time, Tang Xiao confirmed his thoughts even more.

The Juggernaut is here for this vein, and if they use war machines to attack, it is likely to backfire, and if this vein collapses, it is estimated that the entire Duchy of Darkness will sink.

Once the Dark Duchy sinks, the Domination will not get anything, thinking about Tang Xiao nodded secretly.

"Back to the master, these materials are ten times that of high-grade energy crystals, and the energy stones of these energy crystals are ordinary energy crystals. ”

After Yuan Bao finished speaking, Tang Xiao held the high-grade energy crystal in his hand and was excited, this small piece of high-grade energy crystal in his hand turned out to be ten times that of ordinary energy crystal, what kind of concept is this? What is the concept of ten times?

In other words, with one square meter of energy spar and ten square meters at the top, wouldn't such a big vein be issued in front of his eyes?

"Iron hand, let's send it, this is a high-grade energy crystal!"

"High-grade energy crystal?" He had heard of the energy crystal, but he hadn't heard of the high-grade energy crystal, but it sounded very powerful.

"Yes, high-grade energy crystals. The energy of this energy crystal is ten times that of an ordinary energy crystal!"

After Tang Xiao finished speaking, Tie Shou actually laughed, and then stuffed the energy crystal into his pocket.

"What are you doing?"

"Loading energy crystals, can you do it?"

Iron Hand said as he filled all the places on his body that could hold things.

Tang Xiao couldn't cry or laugh a little, this iron hand is too funny. "If you pretend to be like this, can you still get out of that hole?"

After Tang Xiao finished speaking, he patted his head with his iron hand: "That's right, then young master, you quickly collect these high-grade energy crystals." ”

Tie Hand took out the energy crystal in his pocket again and stuffed it to Tang Xiao.

"Just like you, let's follow me to do big things, look at it, people who do big things are like this!" Tang Xiao said with a smug smile, and with a wave of his big hand, a piece of high-grade energy spar on the ground was put away.

Iron Hand's eyes fell to the ground, and he directly threw the energy spar in his hand, it is really better than people to die, and goods have to be thrown away!

Iron Hand feels uncomfortable thinking about it.

"The young master is really a person who does great things!" Iron Hand gave a thumbs up.

"Of course, let's talk about it around the place. Tang smiled and walked forward.

It's so big that it's roughly two-thirds the size of the entire Duchy of Darkness.

You can imagine how big it is.

If this is the case with this entire ore vein, doesn't it mean that there are countless high-grade energy crystals and geocentric lava steels here, and if the level of the system is increasing a little, how powerful the mecha would be to use these materials to make mechas?

Tang Xiao couldn't imagine it anymore. "It seems that the juggernaut has been dealt with. ”

Tang Xiao secretly made up his mind in his heart that he must move more materials out later.

The two of them continued to walk forward, and the more they walked towards the center, the larger the high-grade hedron became, and the small fragments were basically no longer visible.

It's all big here, and a piece weighs at least a few hundred pounds.

The core lava steel is interspersed on the surface, coming and going.

There are even large chunks of geocentric lava steel on top.

With such a large outer shell alone half a meter thick, this amount of geocentric lava steel is enough to make a lot of war machinery, and the war machinery made from geocentric lava steel is definitely not to be underestimated.

Tang Xiao thought as he walked, he thought about how to improve his strength in all aspects, and then resist the master.
