Davis as Machgaogamon was chasing Axeknightmon through a valley as he was making his way to another one of the artifacts.
"Howling Cannon."
Machgaogamon launched his sonic wave, but Axeknightmon launched a blizzard attack to stop it. Then he fired a dark energy blast that pushed them back.
"Now to find the entrance to the hidden valley." Axeknightmon said, but spotted an arrow heading his way. However he stopped it by grabbing it before it hit his face. "Alright what guardian is it this time." He looked over on a cliff and saw a Pajiramon.
"Not another step." Pajiramon said.
"Oh you think so." Axeknightmon said and took one step forward.
"Thunder Stomp."
She jumped down, but he grabbed one of her hoofs. He fired another dark energy blast and brought her into the cliff that opened a door way.
"There it is." Axeknightmon said as he went in. When Machgaogamon got up with the others he changed back and saw Pajiramon down and the opening in the cliff.
"Hey are you okay?" Davis said as they tried to get Pajiramon up.
"Yes thank you." Pajiramon said as she tried to get up. "I must go down there and stop him."
"No you're hurt." Kari said.
"An artifact of the sovereign is down there right?" Zane said.
"Yes. Zhuqiaomon's feather." Pajiramon said.
"We'll handle Axeknightmon." T.K. said as they made their way into the opening that lead them down under the valley. As they made their way down the path seems to have gone on forever.
"This tunnel seems to go one forever." Kari said as she wiped her forehead.
"Wew hot." Davis said.
"Davis." Kari said thinking he was talking about her.
"No I mean it's hot down here." Davis said.
"Davis is right." T.K. said as he fanged himself with his hat. Soon they were shortening their sleeves and pants.
"Hey I think I see the end." Zane said as they made it to the bottom and saw a chasm with rivers of magma. "Are in the core of the digital world or something?"
"Wherever we are we need to find Axeknightmon." Davis said as they started heading towards the artifact, but they were growing tired easily as it was so hot and hard to move so much.
"Oh man this heat is killing me. How did Axeknightmon make it through with that armor of his?" Zane said.
"Quit you're whining." Davis said.
"Watch it or I'll shove you into that magma." Zane said.
"Okay boys take it easy." Kari said.
"We're all just getting tired, but the sooner we find the artifact the sooner we can get out of here." T.K. said.
"Welcome intruders to the magma valley." They looked up and saw a transparent version of Indramon.
"Nice horsey." Zane said.
"Who are you?" T.K. said.
"I am Indramon, guardian of Zhuqiaomon's feather." Indramon said. "This little thing around my neck." He showed he had a red feather tied around his neck.
"Indramon we don't want to fight. We just want to help you because a monster named Axeknightmon is after that feather." Kari said.
"Why bother talking, these guys don't listen." Zane said.
"I'll leave you to Sandiramon." Indramon said as he vanished and Sandiramon appeared in front of Davis and the others.
"Oh man I hate snakes." Kari said.
"Oh boy four tasty looking snacks." Sandiramon said as he licked his lips.
"Now I feel disgusted." T.K. said.
"However I hate it when my food squirms. Meramon come out come out wherever you are." Sandiramon said as Meramon hopped out of the magma and as they surrounded them they felt hotter.
"We better do something fast. We can't take all this heat." T.K. said.
"I'm on it." Davis said as he used the omnitrix.
"Halsemon!"
He flew up over the others and flew behind the Meramon.
"Tempest Wing."
He spun around creating a tornado and it hit everyone. Zane, T.K., and Kari felt cooler as they felt the breeze, but soon Zane started getting hotter and saw the flames on the Meramon were growing.
"Hey Motomiya knock it off. You're making them flames bigger." Zane said so Halsemon stopped.
"Oh right we had a similar problem." Halsemon said. The Meramon started throwing fireballs, but Kari put up a force field. However in a closed space it was getting hotter.
"It's starting to get hard to breathe." T.K. said. Halsemon flew around the Meramon avoiding the fireballs while Sandiramon went to the others.
"Venom Axe."
He shot a lance from his mouth and it smashed through the force field knocking Kari out.
"If only we can get past that snake." T.K. said. Sandiramon looked ready to eat them.
"Mach Impulse."
Halsemon's blades glowed and launched energy blast that hit Sandiramon in the head. He used his lance again and hit Halsemon knocking him down. Before he could hit the ground Sandiramon grabbed him with his tail.
"I can't break free." Halsemon said. Sandiramon opened his mouth wide and bit down on him shocking T.K. and Zane. Sandiramon tried to swallow him as Halsemon struggled to get out of his mouth. He was able to reach the ultimatrix transforming into Bigmamemon. He was too big for Sandiramon to swallow so he spit him out. Bigmamemon jumped up and pounded Sandiramon.
"Let's get going." Bigmamemon said. T.K. picked up Kari and ran off.
"After them." Sandiramon said as he and the Meramon went after them.
"How come Axeknightmon avoid these guys and we're stuck with them?" Zane said.
"Whoa hold up." T.K. said as they saw gas shooting out of the ground. "Whatever you do, don't breathe into that."
"What about Kari?" Bigmamemon said. "She can hardly breathe in this heat."
"Guys walking candles and a giant snake heading our way." Zane said as they almost had them.
"I got an idea." Bigmamemon said. He jumped up and crashed into the ground. "Quick get on." Zane and T.K. hopped on them, but Sandiramon was just about to bite them. That is until the gas released under Bigmamemon shooting him in the air and Sandiramon accidently breathed into it with him coughing and his sight becoming blurry. They were shoot so far and landed on the ground with Davis changing back.
"That was real risky you know. What if we breathed into that stuff, then what?" Zane said.
"Worry later right now we got to get Kari some help." T.K. said. "She needs some air."
"Alright set her down." Davis said as T.K. placed her on the ground. Davis then got next to her and gave her mouth to mouth.
"This isn't a fairy tale. I know she seems like a princess to you, but come on." Zane said.
"No he's giving her mouth to mouth." T.K. said.
"Yeah I know he's kissing her." Zane said.
"No half of CPR." T.K. said, but he still looked confused. Davis kept going until Kari came up and Davis was panting.
"You okay?" Davis said.
"Yeah thanks." Kari said as she was blushing.
"Now we need to get to the artifact." Davis said.
"Actually I think we're here." T.K. said as they saw a giant statue of some kind of bird a few miles away. They started walking until they reached it.
"Now that's what I call big bird." Zane said.
"Amazing, most don't make it this far." They looked ahead of them and saw Indramon.
"Indramon please give us the feather." Davis said.
"You'll have to take it from me." Indramon said as he had the horn on his back float in front of him.
"Horn Of Darkness."
He blew into the horn and launched a sonic blast that blew all of them back.
"We have no choice. We have to fight." Davis said.
"But Davis we can't fight in this heat." T.K. said.
"We have to try." Zane said as he absorbed the ground. He turned his hands into spike maces and tried to fight, but Indramon blocked him and pounded him. He was covered in stone for a few seconds, but was already getting hotter.
"Zane you can't fight in stone, it's only making you heat up more." T.K. said.
"Yes, those who do make it can't last against me." Indramon said as he pounded Zane again. Zane tried to get up, but he was too exhausted he fell down. "See what I mean." He faced the other three and started blowing into his horn, but they moved out of the way.
"How do we beat him? He's too powerful and we're too exhausted." T.K. said. Indramon blew his horn at him, but T.K. wobbled out of the way and caused a rock slide on Indramon, but he broke free.
"Mehemuso…." Kari tried to cast a spell, but she was standing on her hands and knees and didn't had the strength.
"I know who can beat the heat. Agunimon." Davis said as he tried to use the ultimatrix and transformed.
"Tyrannomon, who I didn't want."
"Wait Davis, Tyrannomon has fire attributes. He isn't affected either." T.K. said.
"Hey you're right I feel better." Tyrannomon said.
"Even so you can't beat me." Indramon said.
"Well I'm about to get stronger." Tyrannomon said as he hit the ultimatrix.
"Tyrannomon digivolve to….Mastertyrannomon"
Indramon was about to blow in his horn, but Mastertyrannomon hit him with his tail and grabbed a rock.
"Put a rock in it already." Mastertyrannomon said as he shoved it into his horn.
"Master Fire."
Mastertyrannomon blasted him with his fire and pushed him back and made him drop his horn. When Indramon got up he was mad, but noticed the artifact is gone.
"The feather where is it? Indramon said, but was blasted in the back.
"Thank you again Motomiya." Mastertyrannomon looked ahead and saw Axeknightmon and he had the feather. "I would have never got this without you're help."
"Axeknightmon!" Mastertyrannomon said as he ran at him, but Axeknightmon held his hand out at him stopping him. He raised his hand and blasted the ground above him and the whole place started to cave in. Mastertyrannomon got a hold of the others and made a run for it. Mastertyarranomon was able to make it to the entrance and made it out with the others before the entrance collapsed with the others regaining their strength.
"What happened?" Kari said.
"Axeknightmon did it to me again." Mastertyrannomon said as he changed back.
"So he got the artifact." Zane said.
"Yeah so now we only have one last chance." Davis said.
