Invicinble Colorless Butler

Two pillars of light, one blue and the other gray, pierced the sky and collided with each other. This phenomenon was seen not only in the territory of the Rubelia Kingdom but also throughout the Clorius continent. The two gigantic aura blades made a long space tear in the sky and looked like they were splitting the continent.

"Aaaaaaahhhhhhhh!"

"Aaarrrrggghhhhh!"

Ziel and Archaic Knight roared and thrust their swords at each other. They destroy everything around them, and it continues to extend several miles from their location.

"I don't have much time! I must kill him immediately!" Ziel's face became grave under the pressure of the Archaic Knight's attacks and the passing of time. Almost thirty minutes had passed since Azalia was injured, and Ziel only had less than five minutes to kill his opponent.

"Aaaaaaahhhhhhhhhhhhhhh!" Ziel forces every cell in his body to work to its full potential. He released all his remaining strength, and his vision became blurry from using the power of the two continent guardians beyond his body's limits. But Ziel didn't care about that.

The size of the giant gray pillar suddenly increased significantly and suppressed the blue pillar. The Archaic Knight gritted his teeth and tried to fight back. But his efforts ended in vain. His aura blade was pushed out entirely and then cut off.

"Hahaha!" The Archaic Knight laughed in satisfaction when he saw his attack cut off. A gigantic gray aura blade fell on him and sliced through everything in its path.

Booooooooooooooooooooooooooooommmmmmmmmmmmmmmmmmmm!

When that aura blade clashed with the ground, the entire Clorius continent shook violently. Fortunately, the attack fell on the earth dragon desert. If not, then the casualties and the damage would be terrible.

Ziel's aura blade carved scars in the sky and on the ground. The attack split the earth dragon desert in half and created a vast chasm hundreds of kilometers long. His battles with the continent's guardians always changed the terrain around him. But Ziel didn't care about that. He walked closer to the location of the Archaic Knight. It didn't take him long to find his opponent's whereabouts because the other party spoke first when he saw him.

"Hahaha... you won! You're amazing. No wonder the other two guardians died at your hands." The Archaic Knight laughed with satisfaction. His current condition was pathetic.

The Archaic Knight blocked Ziel's attack head-on, and half of his body disappeared. Right now, the Archaic Knight spoke only with his upper body. He didn't have extraordinary regeneration abilities like the nine-headed imperial dragon and the Sacred Demonel. Therefore, his current state was the same as waiting for his death.

"Did you enjoy the battle?" Ziel asked weakly. He forced himself to maintain his consciousness even though his entire body screamed in pain and barely had the strength to stand up. After confirming the Archaic Knight's death, Ziel still had to go to Azalia's place and treat her.

"Is that so?" Ziel smiled. He didn't have a bad impression of the Archaic Knights compared to the other continent guardians. If not for what he had done to Azalia, he would not have wanted to fight her to the death. But Ziel knew that was impossible.

The Archaic Knight was the guardian of the continent, and he had to hunt down the irregulars. If the people the Archaic Knights targeted had nothing to do with Ziel, he wouldn't care about him. Unfortunately, Azalia and Lilith were on that list. What's more, Ziel was also the one the continent's guardians had to eliminate. So the situation where he had to fight against the guardians of the continent to death was impossible to avoid.

"Of course. It's time you killed me. Otherwise, your little sweetheart might die. But before that, allow me to give you a warning. The last guardian of the continent is powerful. Even if the three of us joined forces, we were no match for him. That's all I want to say to you. Do it now." The Archaic Knight closed his eyes slowly.

Ziel's face changed when he heard the Archaic Knight's words. But that was only for a moment as his expression quickly returned to normal.

If the Archaic Knight's words were valid, it would be impossible for Ziel to defeat the last continent's guardians with his current strength. Ziel, Azalia, and Lilith would die if that creature appeared in this world. But he quickly shook off that thought because there was no point in worrying too much about something that hadn't happened yet. It was a problem in the future, and he would find a way to solve it once his business was done.

The most important thing right now for Ziel is to save Azalia. Just like what the Archaic Knight had said, a little too late, Azalia might die. Ziel looked at his opponent indifferently.

"Goodbye." Ziel swung his sword and cut off his opponent's neck. After the head was separated, the Archaic knight's body turned into blue light particles and entered Ziel's body.

Ziel was silent and let the light particles enter his body. He accepted it calmly because it wasn't his first time. The same thing happened when he defeated the other two continent guardians. But Ziel still doesn't know why it happened and intends to find out in the future.

After all the light particles were absorbed into his body, Ziel quickly went to Azalia's location. He flew with all his might. Even so, his speed was slow because his remaining strength was limited, and he would use it to treat Azalia.

Ziel's face was pale, and his breathing became even more labored as he was still exerting himself after the heavy battle. It didn't take him long to reach his destination.

"Ken..." Azalia quickly noticed Ziel's presence. When she saw him, Azalia's chest hurt because Ziel's current condition was terrible. Even though his body was intact, just by looking at it, she could tell that Ziel also felt the pain that was no less than her or maybe more. Ziel forced himself to walk to that place just for her. His actions made Azalia feel both happy and guilty.

Aghares looked at the scene with a complicated face. First, he was surprised that Ziel managed to defeat the Archaic Knight. Second, his current state looks terrible, and that's because Ziel fought to save Azalia.

Aghares is simply at a loss for words. He felt he had to leave that place to give Ziel and Azalia alone time. He would entrust Azalia to Ziel because he was sure that Ziel wouldn't hurt her after seeing his battle for Azalia.

"Ken..." Azalia mumbled his name again, and tears spilled from her eyes. She struggled to move her hand in her weak state and reached out toward Ziel. But suddenly, she lost her strength, and her hand fell. Ziel quickly reacted and caught her.

"I've killed him. I'm sorry for making you wait." Ziel smiled and squeezed her hand gently.

"I know you can do it." Azalia was taken aback by Ziel's actions but smiled broadly like a blooming flower and squeezed his hand back.

"I will heal you." Ziel looked at Azalia's wound and said seriously. Azalia nodded in response and entrusted her soul and body to him.

[Time Rewind]

A giant spirit circle appeared behind Ziel and rotated. Then Azalia was enveloped in the warm gray light and the wound on her chest slowly healed.

"Thank you, Ken." Azalia said with a big smile and raised her body slowly. But she found it strange that there was no answer from Ziel. When she looked at the man in front of her, Azalia saw Ziel's body stagger and suddenly fall on her.

"Ken! Ken! What happened to you, Ken!" Azalia shouted in a panic, and Aghares, who were moving away from them, quickly returned.

Ziel heard Azalia's scream, but he didn't have the strength to reply. He had used his last power to treat Azalia. After he confirmed that Azalia was safe, Ziel felt calmer, and his body could no longer endure his terrible state.

"Ken… Ken…" Ziel could still hear Azalia screaming his name, but his consciousness slowly faded and sank into the darkness.

***

"Ugh!" Ziel slowly opened his eyes and tried to move his body. But what he felt was excruciating pain. Ziel's external injuries had been healed, but the muscle trauma and side effects from using the two continent guardians' powers that exceeded his body's limits still hadn't completely disappeared.

When Ziel opened his eyes fully, he saw an unfamiliar ceiling and could tell he was lying in a room. According to his last memory, he should have been outdoors, not far from the border between the Rubelia Kingdom and the earth dragon desert.

When Ziel tried to get up and check the situation, he heard the door opening. He saw a beautiful white-haired woman enter the room carrying a tray with many plates of food on it. That woman was Azalia and had cared for Ziel since the other party lost consciousness.

"Ken! You're awake!?" Azalia hastily placed the tray in her hand on the table and then trotted over to Ziel.

"Azalia? Where am I now?" Ziel tried to get up from his bed.

"You shouldn't move your body much for a while. We are now in a lodging near the borders of the Rubelia Kingdom and the earth dragon desert." Azalia said worriedly and didn't want to see Ziel push himself again. But Ziel insisted on lifting his body and checking his current condition.

"I'm fine. You don't have to worry about me." Ziel smiled at Azalia, and it calmed her down. After Ziel managed to sit up on his bed with Azalia's help, he closed his eyes and started examining his body. Azalia knew what Ziel was doing. Therefore she kept quiet so as not to disturb Ziel's concentration.

"Haa..." Ziel let out a sigh of relief after knowing that nothing serious had happened to his body. Then he looked at Azalia, sitting on his bed with their skin touching.

"How is your condition?" Azalia looked at Ziel with a worried face. Even though she had checked his condition, it was only external wounds and some of his vital organs. Azalia was afraid that there would be abnormalities in Ziel's body after being injured in that battle.

"My body doesn't have any abnormalities and will recover soon after I use my skills. How long have I been unconscious?" Ziel released a giant spirit circle, and his body was enveloped in the gray light. The pain from the side effects of excessive use of the continent guardians' power slowly dissipated, and Ziel's pale face became rosy.

"You were unconscious for six hours." Azalia looked at Ziel with concern.

Ziel raised his eyebrows after hearing Azalia's answer. It was already nighttime outside if he had been unconscious for six hours. After his body fully recovered, Ziel got up from his bed. He had to return to Kalya and the girls because his business there was done. He didn't want the girls to worry about him.

When Ziel stood up, Azalia grabbed his arm and gripped it tightly. She looked scared that Ziel would leave her and tried to stop him. But Ziel misunderstood her actions.

"Ah, I forgot about that." Ziel took two world altar fragments from his space storage and handed them to Azalia. He remembered that before separating from her in the Beast Kingdom, Azalia had said she would take the world altar fragment from her when they met again, and Ziel had almost forgotten about it.

"Eh?" Azalia was surprised because she didn't mean to ask for the world altar fragments but to prevent Ziel from leaving her. She didn't know how to respond and feared that Ziel would misunderstand her. If she accepted it, it would be the same as confirming what Ziel was thinking.

"Hmm? Why don't you take it? I'm sorry that I forgot about it. Please take it. I must return to the Aurelia Kingdom immediately." Ziel gave the two World Altar fragments into Azalia's hands, but the other party suddenly released them, and the two objects fell to the floor. Her actions made Ziel confused. But before he could question it, Azalia finally opened her mouth.

"Do you have to go back now?" Azalia looked straight into Ziel's eyes. Her eyes were teary, and she looked like she could cry any moment.

Ziel was a little surprised when he saw Azalia's sad face and couldn't immediately answer her question. After a long silence, he sighed and finally spoke. Ziel had to return immediately and check on the girls' situation. Even though he knew they were not in danger, he had to confirm with his eyes. But before Ziel could open his mouth, Azalia suddenly hugged him tightly.

"Am I not important to you?" Azalia looked at Ziel with tears flowing from her eyes.
