The Deadly Teams Challenge**

**The Deadly Teams Challenge**

At the party, where everyone was enjoying themselves, the king of the demonic family emerged, accompanied by the Sin of Pride. The king spoke with great pride and dignity:

"Ladies and gentlemen, we are gathered here to celebrate a thousand years of our family's existence. Tomorrow, we will send our strongest trainees to the arena of deadly battles."

Then, the king of pride spoke: "In the arena, our strongest trainees will face off against trainees from other kingdoms affiliated with us. The rule is that seven individuals must survive the battles, and these survivors will become members of the Black Storm. This is no less important than the Crimson Order. The time for the battles has been set for two days from now, so I command all trainees to increase their strength and train well. We will meet in the arena in two days."

The king and the Sin of Pride left, leaving the demonic boy in a state of confusion. After the party ended, everyone headed to their rooms. The demonic boy walked with the golden boy to their rooms, as they were next to each other. The demonic boy said:

"See you in two days. Train well, for in the end, no one is strong enough to enter deadly battles."

"Of course, but I wonder who we will face and what the classification will be?"

"I don't care, but I hope we don't face each other."

"Why, are you afraid I'll defeat you?"

"You won't defeat me, for I am the strongest."

They laughed and talked a bit more before the demonic boy left the golden boy. Suddenly, Asmodeus appeared. Asmodeus took out a red book and said:

"Take this."

"What is this book?"

"This is the Book of Blood Control. Learn its contents along with the forbidden techniques. I want you to win badly."

Asmodeus then left the demonic boy and departed. The demonic boy entered his room, followed by Alexander. Alexander said:

"So, what are we going to do?"

"Let's return to our world and learn the techniques, then come back here."

"Alright, I will open a portal!"

The demonic boy returned to his world. It was one in the morning, and no one noticed his disappearance because time in the underworld passes faster than in the natural world. The demonic boy sat on the ground, took out the books, and Alexander sat before him. He opened the book given by Asmodeus, the Book of Blood Control. He found pictures of the techniques, their names, and how to activate them.

"To use blood control, the user must have already activated the red aura before using the techniques."

"Luckily, I have the aura of rage."

There was a talisman for activation. He read the talisman and continued reading. Suddenly, there were cat sounds in the place, the howl of a dog, and intense movement in the area. He ignored it and continued reading. It said:

"Spread the aura in your blood, feel every drop of your blood moving, then transfer your aura into your opponent's body. After that, you can control his blood, either stopping his heart or causing severe internal bleeding."

With each word, the cat sounds grew louder.

Then, a sound came from one of the books, a musical sound. The demonic boy looked to find which book it was coming from and found it was the one given by the girl. He opened it, and a loud scream came out, causing a ringing in his ears. He threw the book, and the pages turned by themselves, stopping at a specific page. It read:

"King Tremendor the Great, ruler of the Lunar Empire, the greatest rival of the sins.

Religion: Islam

Power: Extremely dangerous

A new mission for you, seeker: Find the Lunar Empire and search for the demonic girl."

The demonic boy, shocked, said: "How...how did I forget about the demonic girl? I forgot to search for her."

Alexander said: "We will search for her, but the most important thing now is the deadly teams. We must win."

"You're right, but I swear I will find her and uncover the mystery."

The demonic boy and Alexander trained on the forbidden techniques and blood manipulation. Meanwhile, the golden boy trained with all his might but was hiding something.

Two days later, everyone entered the arena, joined by many individuals from other kingdoms. There were many spectators from all the kingdoms, and a row was reserved for the kings. Then, the Sin of Greed stood and said:

"We are here to choose who deserves to represent the sins and who will join the Black Storm members."

The fighters are:

The demonic boy, the golden boy, and Fantine from the demonic family.

Everyone looked for the demonic boy as if they had heard the name of a ghost. The Sin of Greed continued:

"From the Kingdom of Ariana: Liana the Eternal, Mirar of the Moon, Ryan of the Sun.

From the Golden Sultanate: Damas the Invincible, Zeno, Ariwey.

And the last team, from the ruins of the Hidden Kingdom: the sole survivor of the Nazaki family, Origami Hiroshi, and Usagi the Ice Controller, and Kaio."

"The combat system: we will choose opponents randomly, and they will fight in different environments with different settings. There are no rules; killing is allowed. The last seven survivors will form the Black Storm.

The battles start now."
