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

"Bah, bah, bah~"

Breaking into a sunken underground mine entrance, several people were spitting out sand from their mouths frantically, their bodies shaking and swinging back and forth wildly.

Strands of electric light wrapped around their bodies, making crackling sounds.

After a while, several people fell to the ground with tired and dusty faces, groaning softly, their whole bodies still shaking.

"Heilong, is this the mine?" Wang Dadong asked tiredly.

"Yes, the mine... the mine, the mine is right underneath. This place was dug by Lei Long and I back then... ahem, back then."

"My dad?" Rex fell silent.

"Hmm..." Black Dragon also fell silent.

It seemed that he remembered the glorious past of the Military Arbitration Office, and also remembered those old brothers, whose hearts should have been as hard as stone.

It's inevitable that a trace of regret arises.

However, Black Dragon quickly suppressed these thoughts and looked around the mine.

After a careful observation, he found no signs of newly mined mines. It seemed that no one had ever discovered the mine that he and Lei Long had dug out.

I guess...

Deep in the mine, there should be real thunder crystals.

"Hey~"

Wang Dadong jumped up, his fighting power index soaring.

Then, he laughed loudly and said, "Okay, I'm fine. My internal injuries are healed!"

The laughter was so loud that the entire mine cave was shaking slightly, and some dust was shaken off. Rex and King Arthur were so scared that they immediately held him down.

He covered Wang Dadong's mouth roughly and fiercely, and hit him hard on the forehead with his fist.

"Wang Dadong, are you really going to kill us all?" Heilong punched him on the head, causing Wang Dadong to burst into tears.

"Fuck, you megalomaniac, are you going crazy?" King Arthur said viciously.

"If the mine collapses, we'll be finished." Rex also broke out in a cold sweat and carefully observed the walls of the mine cave.

Fortunately, after Wang Dadong's mouth was covered, the cave stopped shaking.

The three of them breathed a sigh of relief, feeling that they had escaped a disaster.

They almost, almost got taken to hell by Wang Dadong. They were still weak and the mine really collapsed.

No one can escape, they will be buried alive in the mine caves.

"Wuwuwu~" Wang Dadong struggled.

The moment Rex let go of him, Wang Dadong threw his head to the ground, holding his head, "It hurts, it hurts, it hurts... It hurts so much... Wuuwuwu..."

In those few attacks just now, Black Dragon, Rex, and King Arthur all held back.

In addition, Wang Dadong trusted his brothers, so he did not use his fighting power to protect his body or his head, but directly took these fierce punches with his head.

I almost smashed his head, it would be strange if it didn't hurt.

It was visible to the naked eye that there were several lumps of flesh on Wang Dadong's head, with a hint of heat coming out of them. It was painful just to look at them.

After mumbling for a while, Wang Dadong stood up with tears in his eyes.

"Hahaha~" Black Dragon laughed while holding his stomach.

"Little friend Wang Dadong, you look just like those bald donkeys in the water space-time. If they saw you, they would definitely tie you up and worship you like a Buddha."

"Quack quack~~~"

The black dragon almost laughed like a duck.

With a forehead full of lumps, he looks no different from Buddha.

"Black Dragon..." Wang Dadong gritted his teeth. He had hit this guy the hardest just now. Subconsciously, he grabbed the dragon-patterned griddle, ready to have a fierce fight with this guy.

"Pfft~"

Coincidentally, two laughs were heard from the side.

Wang Dadong immediately looked over with resentment, only to see Wang Arthur and Rex's cheeks twitching as they pretended to look expressionless.

To show that the laughter just now definitely did not come from them.

"Ahem~" Rex coughed lightly and suppressed the smile that was difficult to conceal.

"Everyone, hurry up and recover. Going down to the mine to find the Thunder Crystal is the most important thing. Dadong, see how much of the Yuangui shell has been swallowed?"

"3%..." Wang Dadong said unhappily.

"Teacher, this thing is amazing. It swallowed so many thunderstorms, but it only has this little energy reserve. How much does it need to eat to be full?"

All the way to the mine, starting from stepping into this space-time gap.

They were struck all the way to the mine, and were hit by at least two hundred lightning strikes as big as buckets.

Except for a small part that escaped, ninety-nine percent of the thunderstorms were swallowed by the Yuangui turtle shell.

As a result, it only absorbed 3% of the thunderstorm energy. If it wants to fill it up, it will have to endure at least thirty or more thunderstorm attacks?

They were almost exhausted just from withstanding these two hundred or so thunderstorms.

Who dares to hold on any longer?

The black dragon stared at the Yuangui shell with greedy eyes. Only then did he realize that this thing was actually a treasure that could swallow so much thunderstorm energy.

If it is released one by one, will it have the same effect as the Thunder Pool Liquid?

Robbed him?

After thinking about it in his mind, Black Dragon put the idea aside. He still remembered that Lin An said he had left a tracking mark on him.

Although he didn't find the mark, he suspected that Lin An was deceiving him.

but...

It is better to believe it exists than not to believe it. He, Black Dragon, does not want to become a time and space wanderer. For the sake of a so-called treasure, he will not even dare to go back home.

Besides, he was afraid that if he snatched the things and ran away, Lin An would take his anger out on Hong Long.

"Those thunders are the energy dissipated from the entire thunderstorm magnetic zone. Because of the influence of the thunderstorm magnetic zone, natural thunder forces are formed." Black Dragon took a breath and began to explain.

"Go down..."

The black dragon pointed deep into the mine.

"As long as we can find a Thunder Crystal, let alone two hundred thunderstorms, even five hundred or one thousand thunderstorms cannot compare to a Thunder Crystal."

"His father dug out a real thunder crystal from here, and only then did he succeed in breaking through from master to grandmaster."

The black dragon nodded and pointed at Rex.

In fact, the Lei family also has the opportunity to become a supernatural family and stand out in the Golden Time and Space. After all, Lei Long is a master-level supernatural practitioner.

Unfortunately, before he could bring the Lei family to its true peak, they were attacked by a mysterious dark force.

Not only did he fall from the Grandmaster level, but he was also severely injured by the possessed black dragon. He eventually died after being bedridden for several years.

The group of people stopped chatting and quietly returned to their own state.

The one who recovered the fastest was Rex, who was a user with thunder-attribute abilities. The mine was filled with endless thunder-attribute energy.

This not only allowed him to recover extremely quickly, but also improved his strength.

Next came King Arthur and Wang Dadong. Black Dragon recovered the slowest. He was a practitioner of magic and supernatural powers, and the thunder energy was the most restraining to him.

Therefore, recovery requires slowly refining those thunder attribute factors like peeling off layers of silk from an onion.

"Are you all recovered?" asked Black Dragon.

"No problem, Lao Hei, just lead the way!" Wang Dadong said casually.

"Old Black?" Black Dragon's face suddenly turned black, and he cursed with an ugly face: "You are Old Black, your whole family is Old Black, don't compare me with those Heimer people."

"Noisy, do you believe I'll kill you?"

“Okay, okay, okay…” Wang Dadong said in a cowardly manner.

He had dealt with Black Dragon many times, but this was the first time he saw him lose his temper like this.

Could it be that this guy has some rift with that group of black men, or some deep hatred? It seems like I have to go back and ask Duanchangren about it.

Seeing that Wang Dadong was scared, Heilong didn't hold on to this point. He snorted coldly and walked deeper into the mine.

Seeing this, several people shrugged and followed.

The mine passage is very spacious and stable, and the deeper you go, the more stable it becomes.

The thunder attribute energy became increasingly dense and sticky.
