An old man wearing a white gown slowly descended from the sky. His wrinkled face was frowned, revealing intense displeasure. With his hands clasped on his back, he paused and continued, "Just because you can defeat my disciple, you think you are already mighty, Pang?"

The old man's face was expressing full of mockeries.

"I did not expect that the Castle King will come into being." Old Pang was surprised, he thought that things were now getting out of hand. He clearly knew that he was not a match with this Castle King. After all, the latter was already at the ninth stage of Emperor Realm! A little bit and was about to reach the legendary Overlord Realm!

"But of course." Castle King snorted and revealed his disdain, "You hurt my disciple, you think that I will lie low while watching you beating my disciple like a pig?"

"Well, that's true." Although Elder Pang was not a match against Castle King, it did not mean that he will cower in fear. In fact, he was still maintaining a calm and composed attitude. But of course, inside was a violent torrent of emotions, he then said, "But your disciple here was the one who started everything, isn't it justifiable that I only defended? I guess, as the Castle King, you know this."

"You have a point. However, you still hurt my disciple, so if I don't get revenge, I will not be the Castle King!" Castle King flicked his fingers, and a sword appeared.

Whooosh!

After which, Castle King threw his sword like it was a spear! It turned into a white streak of light dashing towards Elder Pang.

Elder Pang's body shook, surprised. He did not expect that Castle King would attack immediately without hesitation! Furthermore, it seemed like he was unafraid of getting into conflict with the whole Royal Castle! He gritted his teeth and would try his very best to block this attack. But even he successfully blocked it, the attack would still leave a grave injury in him. But what's his choice? He could not evade since there were a lot of people behind him!

Clang!

However, when Elder Pang was already prepared to receive the attack, a familiar figure stood in front of him blocking the sword.

With a dashing dragon-robe and a heroic cape, Elder Pang already knew who this was! His eyes sparkled as his heart felt warmth. This person was the protector of this world, the one who loved and cared for his people so much.

Royal King Zao Dong!

"Callum, I never expected that you will come into being. You, a person who never cared about mundane matters, is now here causing trouble. I wonder if this is a declaration of war against my Royal Castle?" Zao Dong said as he caught the sword from Castle King. After which, he threw it to the side with a trace of disgust in his movements.

"Zao Dong oh Zao Dong, so what if I am?" Callum, the Castle King, sneered, "My White Castle is not afraid of falling out with you. Even you still have a living ancestor buried underground, it won't help."

"Oh, seems that you got some huge backing?" Zao Dong smiled, not even showing a slight of a frown, as if he was already expecting this, "Then, let's not talk anything else."

Whoosh!

Zao Dong dashed towards Callum, taking the offense. Along the way, he summoned his emperor-armament, a green-colored whip, and whipped it against Callum who was in a reachable distance!

"Hmph. Petty attack." Callum snorted and revealed his golden blade, an emperor armament and slashed!

Clang Clang Boom Boom Boom!

The whip and the sword clashed in a very fast manner that ordinary eyes could not see even the afterimages. This confrontation shook the entire ground, making every spectator watching to flew in distance.

Rumble!

Rumbling sounds could be heard as the ground could not endure the fluctuations any longer as it revealed several pits around the two figures fighting!

This stalemate battle dragged too long that the two figures were already getting impatient. However, for the people watching, this battle was so marvelous that it even took their breaths away!

"Such an awesome fight! The two kings are definitely and evenly matched." A Sky Realm cultivator showed his amazement and adoration towards this fight.

"Of course, it is the battle of two beings who were only a step away from the legendary Overlord Realm. What do you expect? Even though they were only exchanging blows without moving from their spots, it is already awesome enough. Only those people like them can achieve this kind of fight." An Emperor Realm cultivator commented.

"However, as you see, since the Castle King is getting impatient, he is occasionally showing defenseless spots. If this continues, he will be at a disadvantage." An old man joined.

"Isn't it good news? After all, the White Castle is hostile against the Royal Castle." Everyone thought the same as the Sky Realm cultivator said this.

Thirty minutes had passed, and still, the two figures were still fighting evenly.

Callum, who was getting more and more impatient, gritted his teeth in indignation. How was that possible that he was evenly matched with this Zao Dong? Take note, Callum was already 86 years-old, while Zao Dong was still a bit young. So even though they had the same cultivation, as an older being, he should have the advantage in terms of experience! After all, he tempered his body with thousands of trials and tribulations.

He refused to believe that Zao Dong was his match. Thus, he flew in a distance to prepare his emperor-class technique!

"You're now going all out?" Zao Dong smiled faintly. Although he had a smile, he could feel a terrible feeling of numbness in his right hand caused of continously whipping without stop. In fact, even his breathing was greatly affected. However, he still maintained his calm composure.

Byukaria and the Royal Knights, who were behind him, wanted to help. However, they knew they were not a match against Callum. Only Zao Dong had the power match him.

"Zao Dong, it seems that you are already about to breakthrough to Overlord Realm, right?" While preparing his all-out attack, Callum gravely said. He was sure about this since he was also about to breakthrough.

The people who heard these words were shocked. Breakthrough to the legendary realm, Overlord Realm soon? They sucked a mouthful of cool air. This was truly shocking!

Zao Dong did not respond this, keeping his mouth shut. He was more focusing and thinking what kind of technique the old man would unleash.

"Whatever, as I am already here, I will not let it happen!" Callum howled. He was now in the final stage of preparing this emperor-class technique when the void shook violently, resulting in his channeled qi getting dissipated.

"Grug!" As he was disturbed, the backlash attacked him as he spat a mouthful of blood.

The void suddenly revealed a crack, and two figures appeared from it. One was a youth, and one was a middle-aged man.

Their eyes were roaming as if they were searching for someone.

"Space Manipulation..." Zao Dong had a grave expression. He felt an indescribable danger stemmed from his instinct. It was telling him to run away because the opponent was too strong. There was only one realm that could grant this kind of power...

"Immortal Realm!" He blurted in horror.
