In the bamboo forest...

There the Royal Guardians and Lariel were. Right in front of the gates made of bamboo. Billie was seen walking towards the gate. He was about to reach his hand to it to knock the door when suddenly, punches, kicks, grunts and battle cries were heard.

"It sounds like there's already a battle going on," stated Intellizo.

"But why would someone attack Kung-guó in the first place?" asked Lariel.

"Yeah. Why would they?" asked Rover.

You can see Leo's right index and thumb fingers on his chin. His eyes narrowed in deep thought as he looked for theories on what he thought was happening on the other side.

"I'm not sure, but I have a bad feeling about this. It could be..."

Before anyone else could reply, Billie slightly pushed the door open quietly. He let out a light gasp to see what was on the other side of the door.

Then, he turned his head to the others.

"Um, guys? You might wanna see this."

With that being said, everyone approached Billie's direction as he pushed the gates open wide. They — except Billie — let out a light gasp.

On the other side of the gate was a Kung Fu battle between the Kung-guó residents and the bandits.

The first thing that caught their attention was how the Kung Fu masters delivered punches and kicks to their enemies and how they evaded the bandit's martial arts delivered to them. The next thing they noticed farther ahead of them were village houses made of bamboo with roofs made of straws. There were also mini-farms beside the houses. Most likely in the front yard.

But the Royal Guardians' and Lariel's eyes were focused on the battle. Then, their facial expressions changed into a mixed expressions of seriousness and determination.

"What made those bandits invade Kung-guó and fight the Kung Fu masters?" asked Rover.

"I don't know, but we have no certain option left," said Billie.

With that being said, they all ran through the gate and began to clash the bandits. Billie was seen punching his way through several bandits before his father was finally on sight. He's also a panda with green eyes. His outfit is a light golden-brown straw hat with a red cape. A cape with two ends wrapped around his neck. He was seen delivering punches and kicks towards another lead bandit while quickly blocking his skills.

Billie then, saw another bandit sneaking up behind his father. This time, he couldn't help but alert him.

"Father! Behind you!"

With that being said, his father was about to deliver a kick when Billie sprang into action by giving the second bandit a direct punch to his stomach sending him flying backwards.

The elder panda turned to him. "Thanks, Billie! It's good to see you home again!"

"Yeah! Same here! You already had my permission to be part of the Royal Guardians!"

His father chuckled in response. "So, now that you're here, let's take down those bandits!"

"Yeah!"

With that being said, the two began to fight alongside each other as a father-son team.

Rover was seen using his flexible martial arts to take down the bandits. From time to time, he used his tail for his seductive moves on the bandits. Most especially female ones. When they became vulnerable, Rover decided to get serious and delivered kicks towards their chests.

Intellizo was seen using his self-defense skills on the bandits coming for them. He succeeded in taking several of them down from time to time, but he was also seen using his wand to do so when needed in order not to get everyone else hurt and not to ruin the whole village-like kingdom.

Both Leo and Lariel were seen fighting alongside each other. Leo used his shield to defend themselves from arrow-shooters while he used his lance to attack several more bandits. Lariel was seen using her bow and arrow to shoot through several more bandits. Soon, there were a few more arrows left. And so, she put her bow around her back and...

Her hands started manipulating fire and formed it into a ball. She then, threw the fireball on one of the bandits ultimately knocking him down.

Leo turned to her in astonishment. He had never seen this kind of power coming.

"Woah!"

As the two lions began to clash the bandits, Leo turned to Lariel with a smile on his face.

"That was great, Lariel!"

"Thanks, Leo, but there's no time for explanation!" said Lariel.

With that being said, Leo gave her a definite nod before fighting alongside her.

Soon, the muffled yelp had caught every hero's attention. They all turned to see Billie being surrounded by multiple bandits, then they all jumped at him resulting in Billie being covered.

"Billie!!!" they all cried out.

"Son!!!" the elder panda cried out.

The Royal Guardians, Lariel and the other Kung-guó residents began to fight back the remaining bandits coming towards Billie. After a few moments of delivering punches, kicks, sparks and making dodges, something boomed in their ears.

"Aargh!"

Once they turned around, they were forced to move their arms up and shield their eyes. Because a golden aura had surrounded Billie. The shield's shape started spinning as rapid as Bashiri's shield symbol did. After a few seconds, the exact same symbol seen at Shinōkoku appeared behind him.

The other Royal Guardians, Lariel and the Kung-guó residents looked at Billie in awe as his feet floated a few centimeters in the air. Somehow, a thought about Bashiri and Billie's destiny to help each other's kingdoms crossed Leo's mind. His lips stretched out a smile as Billie performed a temporal empowered move.

Billie used his hands to perform it for a bit before opening his arms.This resulted in banishing the bandits in the Underworld.
