Ultimate Class One: God rewards hard work, the best class teacher

"Fuck, where is this?" Black Dragon even cursed.

He didn't remember that the group of miners back then were able to dig such a passage under the ore vein, which was almost on the same level as an underground cave.

It is at least several dozen meters wide and several dozen meters high.

The deep passage leads straight into the distance, and it is impossible to tell where it leads to.

Rex closed his eyes, sensing the lightning power in the air, and said excitedly, "Such a strong lightning power. There seems to be something over there."

Rex pointed deep into the passage, his eyes emitting a burning light.

He only stayed in this passage for a few seconds, but he could feel that he could absorb infinite energy with every breath.

Then, just slightly activate the combat power to make it stronger.

Perhaps this power is very weak, but it is endless. If he were allowed to stay here for a while, he felt that he could increase his combat power by several thousand points.

"How weird." Wang Arthur squatted down and took a closer look.

"Black Dragon, does this passage look like it has been hit and gnawed by brute force?"

Wang Arthur touched the wall of the cave and saw traces not far above it, as if it had been bitten by something.

There were also broken pieces of stone that looked like they had been hit by an impact, and areas covered with scorch marks.

All of these indicate that this passage was opened by a terrifying giant beast, which rushed forward and then gnawed it away easily, creating this huge passage.

And these giant beasts seemed to have just escaped from being hunted by others.

"Crypt Thunder Beast?" The black dragon widened his eyes.

"Impossible, absolutely impossible. This passage must be dozens of meters high and hundreds of meters wide. How could that little underground thunder beast..."

"noisy!"

The Black Dragon immediately became alert.

He stared at the depths of the passage, feeling that a thunder beast would burst out in the next moment and open its bloody mouth to swallow him.

Indeed, such a small burrowing thunder beast cannot dig such a large passage.

But the problem was that the tiny burrowing thunder beast had obviously just passed its infancy and had come out to look for food when it encountered them by accident.

Since a juvenile crypt thunder beast has appeared in the mine, the appearance of an adult crypt thunder beast doesn't seem to be a big problem, right?

"What's wrong?" Wang Dadong was still careless.

Looking around, he asked curiously, "Rex, are there any thunder crystals nearby?"

"Keep your voice down, do you want to attract that monster?" Black Dragon said unhappily.

Damn, if he had known that this thunderstorm magnetic area would be targeted by the crypt thunder beasts, he would never have come here. He is so damn unlucky.

Wang Dadong was not worried at all and said with a smile: "Heilong, don't worry!"

"Even if there is a real-world crypt thunder beast, can't we just run away if we can't defeat it?"

"Wow, so confident?" Black Dragon narrowed his eyes and looked carefully at the three little guys, Wang Dadong, Wang Arthur and Rex.

He seemed to have thought of something, and his face darkened slightly.

He could probably guess that Lin An must have made some backup plans for Wang Dadong and the others, so as to ensure that the three of them could escape from the thunderstorm magnetic area.

But he should not have a share in this back-up plan, and this back-up plan is even designed to prevent him, the Black Dragon Demon King.

Damn, there is really no mutual trust at all?

"Go ahead, there should be good stuff!" Rex said excitedly.

Immersing himself in such a place with strong thunder attribute power really made him fascinated, especially the feeling that just breathing could increase his strength.

It was really addictive, and Rex just wanted to stay there forever.

Wang Dadong immediately said: "Let's go!"

Just now it was Black Dragon who was leading the team, but in the blink of an eye, the three of them automatically switched roles and walked directly into the deep passage.

Black Dragon was stunned for a moment, and cursed inwardly, "Damn, having a good teacher is fucking amazing!"

"Why don't I have such a good life?"

After mumbling a few words, Wang Dadong's voice came from the front: "Hey, Black Dragon, are you going to leave?"

"Here it comes! Stop making noise, or you'll be in trouble if you attract the crypt thunder beast." The black dragon hurriedly chased after it.

Now I can only follow these three kids.

Maybe if I encounter a crypt thunder beast, they will show mercy and take me away, otherwise I will just wait to die alone.

The four people walked deeper and deeper into the deep passage, but the passage became brighter and brighter.

"What a magical place! The thunder power is so docile. The further we go in, the easier it becomes. There is no more thunder striking us." Wang Dadong put away the dragon-patterned griddle.

The thunder-attributed forces along the way were extremely violent.

If it weren't for the Yuangui shell that blocked the thunder for them, they would not have been able to reach the depths of the passage, and there would have been several more corpses in this passage.

As we went deeper into the passage, it turned out that it was no longer desolate.

On the ground, patches of indigo moss grew, exuding vitality, and near the moss, there was actually an underground river flowing.

From time to time, a purple-red fish jumped out of the river, accompanied by some flashes of lightning.

"Good stuff!" Black Dragon's eyes almost popped out.

"The purple-scaled red dragon fish is one of the exotic beasts. Its meat is extremely delicious and has the effect of tempering the body, strengthening the meridians, and concentrating the spirit."

"Especially the aspect of increasing spirit, which is to enhance the potential of the supernatural walker!"

There was no need for Wang Dadong and the others to ask, Black Dragon was eager to explain.

The look in his eyes made him want to dive into the river and catch all the jumping fish with one net.

The black dragon stared at the purple-scaled red dragon fish and said, "Wang Dadong, get your teacher's turtle shell and put all these fish back!"

"Damn, even if we can't find the Thunder Crystal, these things will do!"

"Look at this purple-scaled red dragon fish. There must be at least 70 or 80 dragon-patterned scales on its body. One scale is equivalent to about three years..."

"Fuck, the Purple Scaled Red Dragonfish's ancestor!"

"Come quickly..." Black Dragon shouted for a long time, but found that there was no movement behind him.

I subconsciously turned my head to look.

The next moment, he had a dazed look on his face and uttered two words, "Fuck!"

"Where are you people?"

When I turned around, I found that all the friends who were there just now were gone. They disappeared inexplicably. Aren’t you afraid of such a terrifying thing?

Anyway, Black Dragon said he was very scared and almost peed himself.

In the empty passage, he was the only one squatting by the river, looking stupidly like an idiot, thinking about how to catch fish. Everyone else had disappeared.

This is pretty creepy, okay?

"Hey, hey, hey, where are the people?" Black Dragon shouted.

"Don't make any noise, come in quickly."

Suddenly, a head popped out from midair. Wang Dadong said to Black Dragon with disdain:

"Hurry up, why are you dawdling?"

"Otherwise, we'll take all the benefits here, and you can just cry!"

"I...shit!" the black dragon monster screamed.

"How could there be a supernatural barrier here? I didn't even notice it. You little brats... Hey, hey, hey, you little brats are so rude."

Before Heilong could finish his words, he saw Wang Dadong shrink his head and disappear in front of him.

Not caring about the many purple-scaled red dragon fish in the river, the black dragon raised its butt and rushed straight into the supernatural barrier in front of it.

In a flash, it was as if passing through a thin curtain of water.

People have already broken in.

"Can you really come in?"
