On their journey, wielding the magical energy of their summoned creatures, the seven remaining people carrying Aeera continued to accelerate. They had to recover and return to the Saranjana Kingdom. Furthermore, they were accompanied by two witches who had been missing: Rasya and Rania. This would undoubtedly strengthen the human forces.

During the journey, Princess Kalya, the elf, asked to return and ensure Lord Kalandra's safety. Genio was asked by Kalya to accompany Aeera to the human kingdom; he simply wanted to be alone to ensure Kalandra's safety. Genio couldn't disobey the Elf Princess's orders.

Oosh!

A deep sadness crossed Aeera's face, and she finally resigned herself to it, praying that Lord Kalandra would win the war. She realized that if she and her companions were in the battle, it would be difficult for Lord Kalandra.

Forgive Aeera, Lord Kalandra!

Several hours of the long journey had passed, and they arrived at the kingdom's gates, crossing the sky. The gatekeepers noticed the presence of the witches and immediately informed the others. The group on the mission to find the Sword of Lightning had returned.

Had they succeeded? That was the thought of each guard and all the inhabitants of the greatest of all human kingdoms.

Regas signaled for the path to open, and the magical creatures they rode alighted at the gate. Regas was the supreme commander of the Saranjana Kingdom, and it was the most powerful fortress among the nine kingdoms. When the gate opened, King Haruga immediately walked in, followed by several of his soldiers. Haruga noticed Regas was quite tired, perhaps having experienced a fierce battle earlier.

Sera released Aeera's magical bindings, and Aeera looked back, remembering only Lord Kalandra now. She hoped Lord Kalandra would return as soon as possible. Aeera still felt the energy connection, so she was certain Lord Kalandra was still alive.

"What are you thinking, Aeera?" asked King Alex. He remained in the Saranjana Kingdom out of concern for his daughter. He hadn't returned since Aeera and her team left, and he had asked King Haruga to stay temporarily in the Saranjana Kingdom.

"Master... Master Kalandra. He sacrificed himself to fight the remaining monsters alone. He didn't want anyone to get hurt."

The team with Aeera lowered their heads. What Aeera said was true.

Alex smiled, "Don't worry, Aeera. He's the strongest summon you've summoned; he'll definitely return."

Aeera turned to look at her father, a sincere smile on her face. Aeera smiled and nodded. "That's right! Master Kalandra can definitely defeat them all."

"Regas! Has the Thunder Sword been found?" Haruga asked Commander Regas.

Regas saluted with a bow, "We've found the legendary sword, King. Now Princess Aeera's summon is wielding it and fighting against the leaders of the Seven Beasts."

The leaders of the Seven Beasts are powerful, elite creatures. If the summons can defeat the elite leaders of the monsters, then defeating the Monster King and Demon King is not impossible.

"Alright, you all go inside first and rest and recover...!"

WOOOOONNGGGG!

WOOOONNGGGGG!

WOOOOOOOOOOOOOONGG!

What's that, a danger signal! What's happening?

A shouting voice came from above. It was the guards on the front tower. They were exchanging signals of danger. The voices were the sound of a great threat awaiting them.

A soldier flew in on a summoned bird, hastily descending and saluting King Haruga.

"What's wrong, soldier?"

Everyone was shocked and confused, and the soldier almost lost his voice from fear.

"Ra... King, we're under attack from the demon and monster leaders. They've come together to destroy humanity!"

WHAT!

And... a terrifying laughter rang out from afar. Two giants were leading the way, followed by countless troops behind them. The two most prominent giants were the Demon King and the Monster King. How could they possibly work together? Was this the end of the human race?

HA... HA... HA...

***

A fiery sword energy attack erupted, and the only one remaining was Cyton, the leader of the Seven Beasts. A life-and-death battle had been raging for some time in the barren, devastated wasteland. The Raktus Mountains had been reduced to fiery craters, shattered by the war.

The fierce battle had reached its end.

Cyton used his ultimate power, blazing energy surrounding his body. His army of thousands had been defeated, and he was the only one left. If he couldn't defeat the human, he would take them all with him to his death. Dying together wasn't bad. Cyton only hoped that when the summoned beast died, his leader, Horus, would be able to restore the monsters' power. That was his only hope.

Cyton extended both hands forward, the immense energy emanating from his giant hands flaring with flames. Cyton raised both hands, and the ball of energy rose into the sky. It grew larger and larger.

"It's dangerous, Kalandra. He's going to blow up everything around this area. The explosion could destroy everything within a very long radius."

The Lightning Sword looked shocked. It was a heaven-destroying force. A force that could destroy its wielder and everything around them. The monster intended to destroy everything, including itself, in the massive explosion.

"Can't we get away from here to avoid the explosion?" Kenan asked.

"It's too late. The explosion is so fast that no amount of speed can avoid it."

Kenan looked at the exhausted Princess Kalya. He had managed to defeat one of the beast leaders with his own strength. Of course, he was already extremely exhausted. If Kenan had left alone, he might have survived. However, if he had taken Princess Kalya with him, it would have been difficult for both of them.

"Die, all of you! I will take you to hell with me! I will avenge my army!"

Cyton's shout boomed, and the vast energy in the sky turned red, expanding, and it seemed as if the sky was filled with their colors. The energy began to approach, and the earth shook violently, as if experiencing a violent tremor. The ground scattered, rocks and soil rose, cracks appeared, and energy explosions began to ignite.

Princess Kalya looked at Kenan.

"This may be the end of my life, Kalandra. Thank you for saving my mother."

The elf princess's beautiful smile was etched.

Amidst the explosions, and amidst Cyton's thunderous screams and laughter, the Lightning Sword spoke, a word only Kenan could hear.

"There is one way to make you overpowered, Summoned Creature! However, there is a risk that comes with that power."

"What is that, Lightning Sword?" Kenan asked, confused.

"We're performing fusion!"

"Fusion!"

"That's right! We don't have time, I can feel it from the energy flowing from the earth. The Demon King's army is attacking the human kingdom. The Demon King and the Monster King are already on the move. They must sense a great threat from the Lightning Sword that humans have discovered. They will destroy the entire kingdom, and the girl who summoned you is in danger!"

This...

"There's no time left, no matter the cost. I will endure it, at least, let me be useful in this world. Even if I'm just trash in my world!"

Kenan's shout caused the Lightning Sword to ignite the energy of all the swords. Fusion must be performed. And the Lightning Sword will announce the risk when the two merge into one.

"Concentrate, Kalandra! Fusion requires intense concentration. We must not fail to save this world!"

"Just do it, Lightning Sword!"

BOOOOOOMMM! Fusion is done! A powerful explosion of energy erupted, blinding the eyes.
