Alright, the moment we've all been waiting for has arrived: the battle for the Mortal Realm is gonna start!

The following day, all our heroes gathered in the center of Gongmen City. Everything was quiet as no one dared saying one word. It was understandable: they were about to take part in possibly the biggest battle for China of all time. Nervosity was at its peak, even for the most experienced masters. Toka decided to stand up and make a speech for all his friends.

"Guys, before our enemies arrive, there's something I want to get off my chest. Master Yoshi is the bravest man I've ever met. But today, I know many other ones. And women too. Ever since Kung Fu entered into my life, everything changed. For the best. I want you to know that, should I die against the enemy, I won't have any regrets. But that doesn't mean that we won't try to survive! So give your best against all of the, no matter how strong they are! Today, we are China's final defence line and the ultimate alliance of Kung Fu! But one last thing: we don't know how long the battle will last, so try not to use all your techniques at once and unleash your best only if absolutely necessary."

The others were now motivated and all nodded, smiled, threw a fist in the air, or simply shouted to Toka. He really was a good leader.

Suddenly, a portal opened and all the eyes turned toward it. A strong aura then invaded the zone as a familiar peacock/phoenix hybrid dressed in a black vest walked out and dragged his almost uninterested gaze over all the place before looking at the heroes who all got in fighting stances.

"Made it in time?"

"Of course! Tai Lung told us about your plan and we were expecting your arrival!" Po declared with a smirk.

"I wasn't talking to you, Dragon Warrior." Lord Zhan Ju simply said and turned his head as more portals appeared around him and many people came out of them. "Is everyone present?"

"Disciple #9 Ren Jiahao present!" said a white male wolf who was dressed in a strange black and red armour with a red circle on the chest. He had puffy hair and black eyes. "Subordinates Lu Yi, Hu Chun, and Bai Jiao too." Lu Yi is a husky dog dressed in a yellow and brown samurai kimono with a yellow headband around his head and a saber tied to his side. Hu Chun is a strange purple panther guy with metal gloves on his paws. Bai Jiao is a lady swan with a geisha outfit and two fans tied to hier back.

"Disciple #6 Ranshao Xinzang present!" said another male wolf whose fur was red and blue and his eyes were yellow. He was wearing a rice hat and an open cloak. "Subordinates Fire Dancer, Snow Dancer and Thunder Dancer are present too!" Fire Dancer is a beautiful female parrot with light red feathers and light blue tips with emerald green eyes. Her attire consisted of a golden dancing top, bottom and dancing curtains. Snow Dancer is a beautiful female kirin with a snow white body and ice blue fur. She had a black dancing suit minus the curtains. Thunder Dancer is a beautiful female antelope with brown fur and a white belly. Her eyes are pink and she had on a red dancing suit.

"Disciple #5 Cris Zhu present!" Everybody recognized the four-armed bear who had one arm missing. He gave a deadly glare to Koji while announcing himself. Luckily, his three subordinates were still absent.

"Disciple #4 Daocaoren present!" said a pretty intimidating crow with pure dark feathers and green eyes that had yellow globes. "Subordinates Night Flower, Rain, and Lanuola are here too!" Night Flower is a beautiful female wolf with black fur and a light blue tummy, nose and tailtip. She was dressed in a simple white cloth around her chest and a loincloth of the same color around her hips. Rain is an ice blue female parakeet with three spiked feathers on her head and a yellow beak and purple eyes. She had rainbow-colored wings an hour glass shape, a golden top on her chest and a red cloth tied under her hips. Lanuola is a feamle peacock with ice blue feathers and turquoise tailfeathers. She was dressed in an orange pull-over that ended at her ribs and orange pants.

"Disciple #3 Surudoi Kaze present!" said a female crane with white feathers (red on top of her head) who was dressed in a half-red and half-blue jacket with a high collar, which covers the lower part of her face downward, while baring a good portion of the lower half of her large breasts. The jacket has a zipper running along its entire length, which is opened from the bottom upwards. The jacket's sleeves completely envelop her arms, terminating in black glove-like extensions at her extremities. She also had an orange lower-kimono tied by a black belt around her hips which still exposed a lot. "Subordinates Mo Ah, Zi Cui, and Xiang Xiang also presents."

Mo Ah is a female moose with dark brown fur and white horns. She had a white top on her chest and white shorts on. Zi Cui is a female lion with golden fur dressed in a red dressing gown-like robe. Xiang Xiang is a lime green female snake with purple markins on the edge of her eyes.

"Disciple #2 Duan Jianhong present!" said a large bear with dark brown fur who was dressed in a white sumo-like bottom and a red torn shirt. "Subordinates Raptor, Ajar, and Mox are present too!" Raptor, Ajar, and Mox were a brown wolf, green snake, and golden eagle respectively, all wearing what seemed to be imperial forces attires in black.

"Disciple #1 Finn present!" said a male raven with emerald feathers who was dressed in purple shorts with two strings of the same color hanging on its two sides and a strange yellow tattoo on his belly. "Subordinates Okada, Xīshǔn, and Fùyìnjī are here too!" Okada is a strange white reptile with purple markins. Xīshǔn is a kind of humanoid grasshopper with a long tail behind him. Fùyìnjī is a pink cat dressed in a red vest and pants. To be short, they were all strange.

"Commandant Gu Xinzang present!" said a guy with his face hidden by a bull-shaped skull and dressed into a strange white kimono. He also had black gloves on his paws, black boots and had a sword tied to his side.

"Commandant Zise Jiao present!" said some kind of purple goat with bronze horns who was wearing circular silver glasses around his eyes and a fire-themed kimono.

So the whole Spirit Realm Army arrived...

"Hum? I didn't expected all of those guys to be present. How did they knew about our arrival?" Ranshao asked with adjusting his rice hat.

"It's Tai Lung who told them everything." Lord Zhan Ju answered.

"I knew we shouldn't have taken this moron into the army." Surudoi remarked with her wings crossed which angered Tigress, but Po putted a paw on her shoulder to make her calm down.

"Listen to me, Zhan Ju!" Toka suddenly screamed. "I don't understand why you want to destroy our realm! You're a living being like all of us! Why would you want to destroy the world where you lived before?"

The phoenix/peacock suddenly gave an angry glare instead of his usual cool look. "Why I want to destroy this world?! I'll tell you why: it's because all the living beings are lost! Instead of all standing together, they fight each other day after day after day for the dumbest of things like money and power! People like you give the power to cowards who hide behind armoured tools they call guards and have no mercy for even the weakest beings and only cares about their own interest! It's too late to change this, except if I can destroy this whole realm and rebuild it at my own image as its god. By killing this world, all those injustices will die with it for a better one!"

Everybody looked in shock at those revelations. "What?! You want to destroy our world because of some's mistakes?" Po said in shock. "dude, that's not a reason! Think about all the good things you're gonna destroy!"

He rose an eye brow. "Like what?"

Po started counting on his fingers. "Well, there's all the good food that took generations to create, the beautiful landscapes that have grown naturally, love, friendship and so many more that I don't have enough fingers to count them all."

However, Zhan Ju simply scoffed. "Enough with this crap: ATTACK THEM!"

"Looks like the confrontation is unavoidable." Toka remarked. "LET'S GO, GUYS!"

With that, our heroes dispatched and engaged the battle with the Spirit Realm Army.

The first fight was opposing Yang and Tongo Tonga against Hu Chun, the purple panther guy. This last one jumped in the air and shot small shots of Chi at the snakes who slithered to avoid them. "I'm gonna squash you like the stupid reptiles you are!" He shouted with overconfidence before keeping the shots with his wrists.

As they were dodging, Yang and Tongo remembered a conversation they had with Karasu, when he came to their world.

FLASHBACK

"So? What did you wanted to talk to me about?" The ninja raven asked the snakes as they went a bit farther from the lake to talk in privacy.

"Mister Karasu, we want to become stronger." Tongo said with a calm yet serious tone. "Toka and the others are getting stronger every day while the two of us are slowly fading as useless fighters. We don't want our friends to lead all the fights without us. Koji told us you helped a lot to improve. Can you do the same for us?"

The raven rubbed his chin before answering. "Actually, yes, I think there's a way for you to become stronger. Wait." He opened a portal into which he jumped before coming back and handed Tongo a box containing three bubble gums - one red, one yellow and one green.

"What are these?" The big snake asked, holding them in his tail.

"Those pills have been created by the Viper Clan and can power up a reptile being. You must only use them in case of emergency. If that's the case, pick the green first, then the yellow, and if - but I strongly do not recommend it - use the red in last."

They then switched the conversation to Yang as he explained the power he felt, during his fight against Critica, during his travel to the Samoan islands.

"What did you felt when this power came to you?" Karasu asked.

"I don't know." The snake kid replied. "I just saw all my friends were helpless against Critica and I wanted to defend them. It's then that this power came to me."

Karasu smiled. "I think I understand: you possess the Spirit of Youth. It's a spirit that gives its power to a kid warrior and make sure this person remains young for very long and ensure he can defend the world as long as possible. Looks like you're the one to have it in your world."

"Really?" Yang asked in surprise. "But how can I use its power?"

"I'm gonna teach both of you everything you need to know."

FLASHBACK ENDS

Yang jumped on Tongo's back and mixed a jet of poison to a huge gust of wind both with their mouth. "POISON CLOUD!"

Hu Chun jumped in the air and shot many Chi shots which touched the two snakes, hurting them a lot. "Running, running, the cat!" He exclaimed with a laugh as he landed down.

"He's fast..." Tongo groaned. "We're gonna need to be faster, if we are to win!"

Yang nodded and closed his eyes, focusing his energy. Pushing a piercing scream, he suddenly exploded with a jade green energy that nobody ever saw him use before. Once the energy faded, Yang now had a jade aura around him and had strange golden tattoos marked all over his back. His eyes turned golden as well and reflected his determination.

"JADE YOUTH MODE!" He shouted.

"Huh? What's that?" Hu Chun asked before taking back his serious glare. "No matter!"

He shot more Chi shots which Yang blocked with his Jade Barrage. Tongo took out his green bubble gum and putted it into his mouth to chew a bit before he suddenly exploded with orange energy. He jumped in the air and swung his big tail at Hu Chun who dodged, letting him smash the ground, creating a crater.

"Damn! How can they have powered up so fast?!" Hu Chun gulped before shooting more at the two snakes, but Yang again blocked him.

"Time to finish this!" The young snake said before slithering under the purple panther and uppercuting him under the chin with a Chi charged tail, sending him in the air. "Tongo! Finish him off!"

The big orange snake charged his own tail with energy. "TAKE THAT!" Swinging his tail, he smashed Hu Chun right into the ribs as he came back down, sending him to crash into a near building. The purple panther was out for good.

Yang returned to his normal form. "We won! We won! We defeated a Spirit Realm Army member!" He cheered as Tongo smiled at his little brother.

"Yes, we did, little bro." He patted his head with his tail. "Let's go see if anyone else needs help before the effects of my bubble gum stop."

Yang and Tongo won their first fight! However, it was only the first one of the list. Let's hope the others will win as well.
