Card: If you have the right technology, you can do everything

Two bullets penetrated Mo Tianlao's body, and his basic points returned to 0.

"Damn it, I won't let you go, sir, I won't..."

Before Mo Tianlao could finish speaking, his body dissipated, and a silver key fell on the ground.

"Huh, it doesn't look like much. Oh, by the way, you're okay." The black-haired young man turned his attention to the three of them.

"It's okay. Are you..." Asuka asked.

"Oh, my name is Yadi. I am an adventurer. I got involved here because of an accident." Yadi said.

The three of them were a little surprised. The young man in front of them seemed to be about 18 years old at most. He could be an adventurer at such a young age.

After several people chatted, everyone learned about Yadi's situation.

His right hand is actually a mechanical prosthesis that can change freely.

"Hey, your arms are fake. They look just like the real ones." Tenjoin Fubuki said curiously.

"Brother, it's so rude to say that."

"Sorry, sorry, I'm just curious."

Yadi shook his head and said

"It's okay. This was all caused by the car accident when I was a child. The doctor said that if the leg is not amputated, it will be life-threatening."

"But compared to the other things I lost, this hand is probably the least valuable. My family members were all in that car accident..."

As he spoke, Yadi fell silent.

"Sorry, I didn't expect to arouse your sadness."

"It's okay, it's been so long, I've already gotten used to it."

While a few people were chatting, several figures walked up to the edge of the mountain. It was You Yu and others.

Marufuji Sho and they met at the foot of the mountain and walked towards the top of the mountain together.

"Hey, Professor, we are here." Misawa Daichi waved.

The three of them also introduced Yadi.

"Thank you for saving my student." You Yu extended his hand to express his thanks.

"It's okay, Professor You Yu, I just did what I should do." Yadi waved his hand and seemed a little flattered.

"Huh? Do you know me?"

"Yes, you are a famous duel king. I often hear your name when I travel outside."

"That's it."

You Yu took his hand back.

Although this boy named Yadi saved Asuka and the others, he always felt that this boy's appearance was a bit strange.

They and Marufuji Sho came from two directions respectively, and neither wave of people saw the boy.

If this young man had been on the mountain all along, why couldn't Old Mo Tian find him?

If you think about it this way, the appearance of this young man is a bit strange.

Of course, there is another possibility, that is, they saw it by mistake while on the road. After all, this place is so big, it is possible to miss it.

"By the way, did you see a key after you defeated that guy?" You Yu asked.

"Key, are you talking about this key?" Yadi took out the silver key that Mo Tianlao had dropped.

"Yes, that's it."

After You Yu took the key, he took out two more. Now all three keys, gold, silver and bronze, were in his hand.

"According to what that guy said, there should be a gate on this mountain." You Yu said.

"As for the door, I saw a door in the cave over there." Yadi pointed to the distance and said.

"Then let's go and take a look first."

Yadi led everyone to the cave, where a dark door stood in the cave.

The door is covered with twisted patterns, and behind the door exudes a terrifying dark power.

"You guys stay away. If something goes wrong, leave as soon as possible. Do you understand?" You Yu said.

"Professor, you have to be careful too."

You Yu nodded and inserted the three keys into the door.

Click, click, click

The door slowly opened, and the dark atmosphere gradually began to spread.

The door to the dark world slowly opens

"I didn't expect you to come here. It seems I really underestimate you."

A huge demonic dragon stepped out of the darkness.

[Dragon God Grafa of the Dark World]

You Yu frowned after seeing the other party's true form.

It wasn't that he was afraid of the guy in front of him, it was just that he felt something was a little wrong.

The star rating of the total card in the elf world represents the level of the monster.

The previous [Mysterious Execution God] was a ten-star monster, but the [Dragon God Grafa of the Dark Realm] in front of me also bears the name of a god, but it is only an eight-star monster.

The level difference between the two is too great.

"Are you the Four Dark Kings?" You Yu asked.

"Exactly, today is the day you die." Grafa snorted.

"Stop talking nonsense, if you want to kill me, you have to have that strength." You Yu said disdainfully.

No matter what the problem is, the most important thing at hand is to defeat this guy first.

"Then it's as you wish."

Grafa stamped his foot, the ground cracked, and a huge stone platform rose up from the crack. On the stone platform was a set of dark cards.

[Special status: [Gate to the Dark World] is always activated. 】

"duel."

"duel."

"It's my turn to attack first. On my turn, draw a card." Grafa drew a card from the deck.

"I activate the magic card [Dark Corridor] and add 1 [Dark World] monster from the deck to my hand. Choose 1 card in your hand and discard it."

"I add [Cerulli, Tutor of the Dark Realm] to my hand, and then discard [Cerulli, Tutor of the Dark Realm]."

"The effect of [Ceruli, Mentor of the Dark Realm] is activated. If this card is discarded from the hand to the graveyard by the effect, this card is Special Summoned in Defense Position on the opponent's field."

"And this card is activated when it is successfully Special Summoned by the effect of the [Dark World] card. The opponent selects 1 card from his hand and discards it."

Graffa said.

"Hey, if the opponent's field is Special Summoned, and then the opponent discards a card, doesn't that mean that this card is Special Summoned by Professor Yu Yu, and then he discards a card himself." Sho Marufuji thought for a long time. Finally figured out the relationship.

"The other party must have some purpose in doing this. The Four Dark Kings are not simple characters." Yujo Judai said.

He had fought against the [Xuanhua Execution God], who was also one of the Four Dark Kings, and knew that the opponent would not do such a stupid thing at his level.

"I activate [DD Crow], discard this card from my hand to the graveyard, and banish 1 card from the opponent's graveyard. This effect can also be activated during the opponent's turn."

"I will exclude [Ceruli, the Mentor of the Dark World] from your graveyard."

A crow flew out of the space of another dimension and picked up the card in the opponent's graveyard, and then flew into the other dimension again.

Since the card is excluded, the mentor cannot be specially summoned to his field, and subsequent effects will not continue to resolve.

This card is one of the few usable hand traps in the existing card pool.
