The Silver Knight said with a tone of disappointment as he changed into Solar element summoning his Solar Blade with Aether unsheathed his sword and prepare for battle.
Both Sekai and Aether rush towards Childe in opposing directions and bring down their weapon down on him, forcing Childe to block them with his short swords.
As the three of them begin exchanging blows for brief moment before Childe back flips away from the two of them. But he wasn't going to have any respite because both Aether and Sekai charge towards him again.
This force him to dodge and block every single attack from both swordmen. But Childe know that, they still in the phase of gauging their enemies which he knows he can take advantage of.
Childe quickly changed the situation as he now advanced forward against them changing the tide of fight by forcing both Traveler to defensive stance as he goes offence by unleashing a series of aggressive attack at them, however Sekai managed to counter strike at Childe and directly smash back of his Solar Blade handle on his face.
Sekai: Right there!
Childe: Aughh!!
Childe reels back from the bash the Silver Knight bash at him but he tried to counter back with kick on his abdomen forcing him to Solar Leap away.
Before he could catch his breath Aether emerged out, from above and unleashed his Geo powers.
Aether: Terra-smash!
Childe was barely able to dodge his attack, but Aether quickly changed from his Geo to Anemo
Aether: Wind Blade!
As he created a small green orb on his hand and fired at Childe knocking him back into a few distance, Sekai saw this opening take his chance as he Solar Leap above him and was ready to strike.
Sekai: Solar Slash!
Sekai performed an over-slash at him sending Flying Solar Energy in Blade wave from his Solar Blade and it hit Childe directly setting off small explosion afterwards.
This cause Childe to be sent fly towards sideways with great force sending him rolling onto the ground until he crashes into the very rubble he sat on.
Childe: …Wow… You're both strong.
He said before standing up adjusting himself.
Childe: When Signora offended the deities outside the Cathedral in Mondstadt, she plans to just delay Traveller and swiftly left the scene once her mission was accomplished.
Childe: But who know she would pay the price by being beat in the most humiliating way… Now I know why you can defeat La Signora, number 8 of the Fatui Harbinger!
Childe: You may have force her away, but that only because she didn't use Fatui Harbinger Trump Card. Afterall, as powerful she was, she will prioritize her mission, weigh the outcomes and consider the consequences of her actions…
Aether: Are you saying if any Fatui Harbinger get serious we can't never win against any of them?! You're completely delusional
Sekai: It's not like I ever show my trump card when dealing with her…
Childe: Ahahaha! Fighting talk, I love it! Now let's see you live up to it.
Then Childe switches to his swords to his bows and fires at the two men forcing them to separate as Sekai made a quick counter at him when he points out pistol gesture and fire solar beam back at Childe's arrows.
As both energy beam and arrows clash through mid-air, as both Sekai and Childe continue to exchange attack until he is interrupted by Aether who emerged from above again preparing to unleash another elemental skill but he manages to avoid it once more.
However, that was another bluff make by the teamwork of both travelers. Sekai appeared in front of him again then directly punch him straight on the gut with a strong force wearing Quake gauntlet, making Childe puke some blood from his mouth making a trail as he fly towards a pillar, destroying it on process.
After coughing several times, Childe force himself to recover and weep off the blood from his lip.
Childe: Not bad. Your teamwork is quite impressive… But that's about as far as you'll get.
Sekai felt something wrong, suddenly his instinct flare.
Aether: Sekai!
Sekair: !!!
Childe dash towards Sekai in attempt to strike him with the point of his spear.
Aether immediately got to his feet and summon a condensed orb of Anemo with his palm, blocking Childe's attack to shield Sekai. The Electro polearm slowly pierce through the Anemo orb, causing Aether to gasp. He slides his left leg back, ripping the marble floor apart as he reinforces his Windblade with two hands. The torn flooring beneath begins to crystalize in an amber color as Aether calls upon the Geo element, sprouting numerous glowing amber crystals beneath his feet that shot up towards Childe.
An element reaction resulted in an explosion that spew dust everywhere. Paimon found herself flailing wildly in the air as she was hurled back by the explosion alongside Aether who skillfully maneuvers himself in the air to land safely.
When the dust settles. However, Childe is nowhere to be found… only his Electro polearm remained in the crater along with large shards of crystalizing Geo.
Childe: Haha… You shouldn't do that… You just made a distraction for yourself.
Childe spoke next to the Exuvia.
Paimon: You were just playing us to get close to the Exuvia!
Childe: Oh, quite down. Stop acting like some wide-eyed recruit. You've seen this world. You of all people should know… this should have been expected.
As Childe reaches into the Exuvia
Childe: Well then, I'll be taking Moras Genosis now! …Huh?
However, he come out empty-handed.
Childe: Hahaha… I see. Well, this is most unexpected.
Sekai: Ain't that karma for ya.
He said with smirks on his face as Childe went silent. Well Sekai already guesses where the real Genosis was. Afterall knowing Zhongli… with that 60++ century of experience, he will not leave something as precious as Genosis unguarded.
Then Tartaglia looks toward the Silver Knight.
Childe: You… You know it was not here, didn't you?
Childe: You already claimed it yourself didn't you!?
He yelled angrily at them.
Paimon: W—we didn't take it!
Childe: Did you simply move faster? Or… did you leak the information regarding the Golden House to me on purpose?
Sekai: Wow… look at this child… so grumpy after he didn't get what he wants… really… such a misguided brat you're huh… tshk3
Paimon: Sekai! Stop fooling around! You're making things even worse! Aether says something.
Aether: Err… "something"
Paimon only sweatdrop toward her two travel companions' shenanigans.
The silent being break by the sound from Childe direction. They looked up to see Childe floating in the air as the water started to surround his body, combining with electricity. His power started bursting then revealed himself in Foul Legacy form. Tartaglia-Childe-the Eleventh of the Fatui Harbinger
Childe: No matter. Hand the Genosis over, now! Don't make me take it from you.
Sekai: *sigh* such unreasonable child, this brat. If you want it… then you'll have to take it.
He said while he slowly touches his watch.
Childe strikes his spear at them but Sekai back flip away to dodge in midair
Sekai: Guess I have to have the chance to try my new form then… Sekai… Dual Split!
The circle appeared with two elements logo of Solar and Cyclone. He jumped out with two of himself in different clothes and colors.
Childe: Oh. You have finally decided to use a split. Well… it's doesn't matter. If you think two of you can defeat me, then go all out. I won't hold back.
Sekai (Solar & Cyclone): No. We aren't fighting with just this… but this time we will Merge as one!
Other: Huh?!
Both of them are glowing and touching their fist together
Sekai (Solar & Cyclone): Elemental Fusion!
Their combination produces an explosion of elemental energy leaving a smoke of torrential elemental energy around them.
The smoke slowly cleared to other view. A figure slowly approached Trataglia as Sekai slowly revealed himself in different outfits
Sekai: Sekai Solone!
Sekai now adorns Inazuma traditional clothing, with a mix of samurai armor. The variant colors of his outfits are blue, gold and white. He wears accessories on his hair which the emblem is place on it.
Everyone in the room is shocked at his new power.
Aether: What the…?
Paimon: What the heck is this!? He can fuse two elements together without having any elemental reaction!?
Childe: Huh? What is this? You just fused with two elements?
Sekai (Solone): This end right here. Right now. I will stop you.
Sekai said while covering half of his face with a hand fan on his right hand.
Childe: Heh. This is very interesting. Show me what you got!
Childe smirked then sprinted toward him. Sekai stated into a Light Speed Stance and dodged his attack gracefully. Childe slams his spear at him but it only hit Sekai after image as Sekai already jumps up gracefully. Sekai keeps using Solone Light Speed at different spots as Childe keeps attacking him but he only hits Sekai after image. Sekai found the opening and ready to make his counter attack.
Sekai: Solar Fan thrust!
Sekai closes his paper fan forming and imbued Solar energy at the point while boosting the speed of thrust with Cyclone element. He thrust Childe right into his gut sending his flying. He then Solone Light Speed on top of flying Childe.
Sekai: Cyclone Breeze Slap!
Sekai opens the paper fan and proceed to slap Childe cheek creating enough force to make Childe felt humiliated. But that not the end of his technique. The slap was been follow by harsh blow of cyclone throwing Childe slamming towards another poor wall of Golden Chamber.
BOOM!
Childe rise from the smoke held his chest in pain, while wiping blood on his lips.
Childe: Now we' talking!
Childe uncombined his spear into two blades. He sprints towards Silver Knight and slashes him with both sides but just like before, he keeps hitting Sekai after image and once more he was been hit by Cyclone Breez Slap sending him towards the middle of the room.
Sekai: You never learn huh.
He said while covering his mouth with fan and close it. He then closes the fan forming a handle. The close fan forms a short dagger make of Solar element. Solar Dager that look similar to Tanto.
Sekai: It's time to sleep little child.
Childe: Think you can end me. I'm just getting started!
Childe switches to bow and shoots many at him.
Sekai: Light Burst
Sekai form multiple Solar Dager that shoots towards Childe arrows. Childe keep on shooting at Sekai, only to be countered with the Hovering Solar dagger that move like homing missile. This managed to push Childe back and he feel enough was enough.
He then focuses his elemental energy on the ground. The ground is covered with water and something is coming out. It's a big whale.
The whale is falling on Sekai. Sekai concentrates combination of Solar and Cyclone on Solar dagger.
Sekai: Solar Dagger Slice
Sekai makes vertical Slash cutting the whale cleanly separating it into two crashing down between Sekai bursting the area with smoke. Childe is looking around to find him, but he is already move in front of him with Solone light speed.
Sekai: Solar Wind Blast!
Sekai thrust the closed fan right into Childe face with the force of cycle blast, which knock him over the wall again creating a crack sound and his transformation is reversed back to normal. Childe got out of the wall then he is on his knees breathing hardly. The group walked toward him.
Childe: *panting*
Paimon: Look! Childe's back to normal again.
Childe: Ugh, well then… time to cool off. It seems the burden of the Foul Legacy Transformation was too great for my body. I lacked the opportunity to think this through…
Childe: And now that I consider the matter more carefully, you never had any chance of beating me to the Genosis. You had no connection to the Genosis, no matter where it had been taken.
Paimon: That's right! we tried to tell you we didn't take it!
Childe: You. That ability earlier. It is really strong. Your strike injured me heavily. Tell me, how could you have these kinds of power?
Sekai: I wonder what his reaction if he knows I was holding back. As evil as he is, I didn't want to go all out for kill. Afterall, this issue not only about us, it about both Liyue and Shneznaya nations.
Childe: I see. But if that is a secret you both wish to keep, I guess I'll just have to curb my curiosity. The battle has already left me satisfied. Anyone who strive as I do to grow stronger shall be called a friend, even if our friendship can only be shown in battle against one another.
Paimon: Pretty sure that's not the normal way to make friends.
Sekai: Who want to be friend with a child!
Childe: Ahahah… unfortunately, I must bring this amiable conversation to an end. My quest still beckons. Given the Genosis wasn't taken by anyone, then we must look once again to beginning. Perhaps it was never in the Exuvia to begin with. In fact, it might be the Exuvia was just diversion of sorts.
Childe: Yes, it appears so. Interesting to say the least…
While Sekai just gives him a neutral expression, knowing the whole truth. But he still thinks something was missing… it's like there one jigsaw puzzle that missing from the whole puzzle.
Childe: Its seems that the guardian deity of the capital of commerce is also well-versed in the little maneuvers beyond the boundaries of contracts. As such, we must now look to our backup plan.
Paimon: Back up plan?
Childe: I had hope it would never come to this, for the weak will be swept away in the process. The truth is, the world belongs to those who pursue strength. I seldom willingly involve myself with the weak. Unfortunately, we cannot be picky about out methods as Fatui. Children must learn to eat their vegetables sometime.
Paimon: So, what are you planning?
Childe: I will awaken the god that lies dormant beneath Guyun Stone Forest.
Paimon: A god!?
Childe: Osial, Overloard of the Vortex, who was defeated by Morax the Hep Archon in the Archon War, and who has remained pinned beneath the waves by Geo Archon's stone spears ever since/
Suddenly Sekai grabs Childe on his collar and glare at him.
Sekai: What the hell! Are you planning to kill innocent people of Liyue!!
Childe: Using the power of ancient gods in such situation fails to interest me and is largely against my principles. But knowing that such an action will not only force the Geo Archon to show its hand, but you as well… that makes matters a little more intriguing.
Sekai: You bastard…
Childe then summons a swarm of Sigils of Permission forcing Sekai to release him as the Sigil circle around him.
Sekai: Damn it… we all playing in his palm since we meet the adepti.
Paimon: Oh, Paimon remember now! The Fatui have been researching them….
Aether: You've been trying to duplicating them since then.
Childe: Indeed. The one that was—
Sekai didn't give Childe any chance and release his most devasting move.
Sekai: I warn you… but you didn't heed my warning…. Now receive your punishment~
He said in cold tone…
Childe feel cold from his spine and tried to escape by flies out with water surrounding it… Alas… unfortunately Sekai can just Solar leap behind him, readying his close fan with cyclone element.
Sekai: Secret forbidden jutsu, 1,000 years of pain!
And with that word, he thrust his folded fan directly on Childe bottom…. The world went silent for a second. Until Childe shout with disturbing sound.
Childe: Aahhh~
Then the blast of cyclone blasts him from his bottom sending him flying like an arrow head toward Liyue direction….
Sekai hover down only to be greet by Aether thumbs up gesture which he replied with his grin. Paimon seeing this reprimand him for teaching Aether bad things.
…
