Summary/disclaimer: Time for another chapter of Blue and Red Flames. Enjoy the 1100- word chapter. I don't own Avatar, Nick, Michael Dante DiMartino, and Bryan Konietzko do.

(Earth Kingdom, Fissure Base, takes place during The Earth King.)

Diyu watched before firing a bolt of lightning and hitting the Earth Kingdom soldier, killing the man as he fell to the ground, joining his slain men as well as Diyu's non-bending infantry charged past him, swords, spears and bows at the ready as Diyu watched a squadron of Tundra Tanks drive back the Earthbending soldiers as Diyu's non-bending soldiers engaged the non-bending Earth Kingdom soldiers.

"Finish off the rest of them then prepare to move out, we're almost done here."

Diyu said as he turned to face a charging Earth Kingdom soldier as the man launched a boulder at the Fire Nation officer as he dodged to the side before launching a fireball at the soldier, Diyu watched him block it with an earth wall.

"Well, I'm glad the Earth Kingdom's army can still challenge us, it makes me understand how you're still managing to fight the Fire Nation."

Diyu mused as he flipped over a line of quicksand before launching a beam of fire which was blocked by mud before Diyu hit the man in the chest with a flame whip as he fell to the ground, Diyu started to approach him before Diyu was hit by a massive boulder as the attack grazed his arm, causing him to wince.

"Well, your good."

Diyu mused as the man tried to stand before a plume of fire hit him, slaying the soldier as Diyu climbed to his feet and gripped his arm.

"Ow."

Diyu mused as he turned to see his soldiers finishing off the rest of the Earth Kingdom soldiers, hauling away the ones who surrendered as Diyu rubbed his arm as he turned and sighed before he looked up as a caw split the air.

"Fenghuang, what are you doing here?"

Diyu asked as the Messenger Hawk landed on his arm as Diyu pulled a scroll out of its pouch and read the message. Even without looking, Diyu knew it would be from Azula as he read the message.

'To Lieutenant Colonel Diyu….'

Diyu read before clearing his throat and read the rest of the note.

'If Fenghuang was able to deliver this, I'll be brief…. Me, Mai, and Ty Lee were able to fool the Earth King into thinking we are the Kyoshi Warriors…. I haven't spotted the Avatar yet but I have a few other thoughts for now…. I'll keep you updated… But continue your assaults, the less soldiers in the city, the better….'

Diyu read in his head as he read the final part,

'Sincerely, Princess Azula… Well, at least I know all these assaults outside the city have a bigger purpose…'

Diyu thought as he pulled out a quill and turned to Fenghuang.

"Looks like we still have a lot of work to do, eh, girl?"

Diyu asked as he pet the hawk's head.

'Dear Azula.'

Diyu started before looking at Fenghuang and continuing.

'Fissure Base is dust…. Small victory, I know but I'm guessing you have a plan, you always do, I'll march on the next base and send Fenghuang to tell you when it is done…'

Diyu put before finishing the letter and patting Fenghuaang's head.

"If anyone can get this letter to her, it's you, girl."

Diyu muttered as the Messenger Hawk cooed before flying into the air and taking off as Diyu became lost in thought.

'Reminds me of that time me and Azula beat Mai and Zuko in that double duel when we were kids.'

Diyu thought as he remembered the duel as if it had occurred yesterday.

(3 Years ago, Fire Nation Royal Palace courtyards, 2 years before Zuko's banishment.)

12-year-old Diyu flipped out of the way of the flame kick Zuko had aimed at him, he launched a fireball which the prince blocked before Diyu flip kicked him backwards, knocking him into Mai as Azula dodged a round of knives tossed at her.

"You really think you're going to beat us, Zuzu? I've been training dear Diyu myself… Which means we're better then you."

Azula snared as Mai launched a wave of shuriken at the duo, Diyu melted them with a heat wave as Azula grabbed one as if she was catching a ball.

"Seriously, Mai, you're not going to beat us if tossing sharp toys is your only attack."

Azula said, smirking evilly as she melted the throwing star to shards and crushing it under her boat as Zuko growled and charged his sister with fire daggers.

Azula merely smiled as she sidestepped and knocked her brother to the ground with a kick as Diyu hit Mai on the wrist with a fireball, causing her to wince as she tried to throw a sai.

"Nice try… But Azula is right, pointy things and good aim don't win battles."

Diyu said with a smirk as Zuko stood up.

"No, but a little fire might!"

Zuko said as he launched a beam of fire and stream of fireballs at Diyu.

Diyu blocked the fireballs but the heatwave burned his arms as it grazed his sleeve, causing him to fall over.

Azula's smirk vanished.

"Diyu!"

Azula screamed before she turned to Zuko with hatred.

"Your going to pay for that, Zuzu…"

Azula said before her smile returned as she dodged a fire ball before grabbing Zuko's wrist, hauling him to his feet before she twisted his arm behind his back.

"Let me go, Azula!"

Zuko groaned in pain as Azula looked over at Diyu as he nursed the blisters forming on one arm.

"Sure, go play with your girlfriend, Zuzu!"

Azula cooed as she kicked Zuko's foot out from under him, sending the 14-year-old sailing towards Mai as she and Azula sent several fireballs at Mai, knocking the knives out of her hands as Zuko slammed into her, knocking them over.

"That's what you get for hurting, Diyu!"

Azula purred as Zuko groaned.

"Shut it, you're just mad I hurt your boyfriend, Azula."

Zuko groaned as Azula growled in anger.

"He isn't my boyfriend, he's my friend and my servant!"

Azula said, briefly losing her composure as she helped Diyu to his feet.

"Come Diyu, lets get that burn looked at, the royal doctors will be glad to assist you… Zuzu, make yourself look good for when mother gets here."

Azula stated with a sadistic grin as she gently carried Diyu off the courtyard and towards the medical room.

Author Notes

Phew, first of the flashback chapters done! I wanted to post this chapter first to give you a taste that Azula was soft on Diyu… As for why? Next chapter will give some insight into that… Next chapter will take place during The Guru and will explain why Azula cares so much for Diyu and is soft on him. Until Saturday, Lighting Wolf out!
