The Nine World Yggdrasil was a special type of pocket dimension that Caelum bought in the system. It is capable of innately growing alongside Caelum despite not being his true Inner World.
To put it simply this pocket dimension was separate yet connected to Caelum that was created by purchasing it from the system.
He had longed to make it into a haven where his family could live occupying the Asgard realm at the peak of the Nine Realms.
While the other realms are occupied by different races either came from the Yggdrasil in Draconic Deus(DxD) or produced from natural energy that Caelum made.
Though it was not the same scale as the God Domain from Apotheosis, it was at least a million times bigger than the Earth universe and galaxies.
'Fortunately, I didn't try to connect it to my Great Zenith Universe or else everyone would have died.'
Caelum flew into the sky after spending his time with his mother and headed out to the sparring place. He arrived at the large auditorium whereupon entering met with the barren wasteland that had countless large craters.
At the center of it, all were two individuals shrouded in thick aura with one pure darkness enveloping the surroundings while the other was miasmic red that disintegrates everything including the darkness.
"So it's been 100,568 ties, 0 loses, 1 win?"
The red-haired smugly said He had short hair wearing martial art theme clothes showing his muscle despite his small frame.
His words caused the long dark-haired young man who was shirtless with only a long sleeve that covered his hand and buggy pants.
"Screw you! I thought we agreed that we would only use physical strength and not our innate ability!?"
"Tch! I told you I didn't use my Power of Destruction! How about we settle for another round!?"
"Good I'll pummel you for breaking our agreement!"
The power-up that shook the ground from the sheer power they were releasing. It was already amazing to see them standing when space is heavily restricted, having rules that increase the gravity and weaken them to a minimum level.
Caelum watched to the side bringing some popcorn seeing his son progress. Their overall prowess without restriction would be around mid to high True God of apotheosis and Empyrean God from Desolate Era.
A massive explosion resulted in a massive mushroom cloud form reaching the clouds as the two collided perfectly deadlock their first into each other's faces.
The two growls then headbutt each other and shatter the ground and form a small ravine. These two sons of his are rivals in Martial Art proving who was superior.
Though he dislikes conflict within his family, sibling rivalry does help them grow stronger.
Qing Yan took a step back before delivering an elbow strike into Urizen's abdomen only to be caught by his hand then hold tightly before twisting his body that caused Qing Yan to fall due to the offset of the center of gravity.
He then felt his face slam into the ground when Urizen did a roundhouse kick. Urizen smirked, still holding Qing Yan's arms.
However, it was short-lived when Qing Yan grabbed his hand pulling him then slammed him to the ground causing him to let go.
This allowed Qing Yan to take a step back, seeing Urizen standing up from the rubble made him smirk.
"How does it taste brother? Are you giving up?"
"Yeah right! I'm just getting started!"
Without a moment of rest, he appeared behind Qing-Yan who barely caught the speed pushing him a few meters away. Qing Yan took it more seriously and vanished, moving faster than the speed of light and hardly seeing their figure.
Caelum saw it all with each strike perfectly canceling out pushing a powerful shockwave. It took them a whole 3 hours before both grew breathless faster, overexerting their power.
They ended up passing out at the same time gaining the same thought as they fell to the ground.
'Tie again.'
The two were completely disappointed at the result of their endless match that always ended in a tie. Both only use their physical strength and the vitality they had tempered.
Caelum appeared between the two having a proud smile witnessing their growth and using his power to heal their wounds and moments later both stood up ready to fight against only both were hit by a karate chop.
Both wanted to curse whoever did it only to shudder to see them before them menacingly smiling.
"F-Father, is there anything you need? I thought you're away training?"
"Hey dad, were you watching us fight? What did you think?"
"You brat did great but still lacked discipline and flow into your movement. Both of you rush like a War God without thinking. Yan Qing won in physical strength while Urizen won in technique and flow. Overall both of you won."
He gave an honest assessment without placing a favorite. The two were slightly disappointed but their fighting style had the same straightforward manner but the technique and strength was vastly different.
"Bleh next time I'm still not satisfied!"
"Want another round!? Then you're on!"
The two were flaring their aura stupidly forgetting their father was standing in front of them to receive another karate chop.
"Stop fighting! The reason I'm here to bring you with me to the world I'm currently in is. This is the place you two always wanted to be."
"Father, is this place where dogs eat dogs? Where strong means right?"
Urizen asked with hidden excitement from hearing his father's words. His burning desires to fight stronger enemies and trampling them down his feet was the path he had chosen. A Demonic War God.
"Fuxk yeah! Let's head out now! My blood had been boiled for a fight!! Those deity rank Demon Beast were too easy!"
His brother shares his opinion ready to pummel some expert having the raging ambition to finally fight and explore.
"Hold on, tell me what rank is your soul, body, and energy?"
"I'm at peak Supreme rank in the soul, my body is Empyrean God and my energy is at the Upper Divine Transformation Realm."(Urizen)
" As for me, My soul and body are the same but my energy is at Lower Realm Lord."(Qing Yan)
"Tch you only surpassed me this time but that won't be long!"(Urizen)
"Wanna bet!?"
'This two…'
Caelum ended up scolding the two again before they headed to get Ryuu from the deep mountain where he crouched down before the forest was precisely sliced in half letting them see the person responsible.
It was a young man with short dark hair breathing deeply holding a hilt of a Katana that had its blade shattered. However, movements later the fragment started to hover and assemble itself at the hilt.
[A/N: Scissor Seven Mc that's Ryuu]
"Damn Ryuu! You almost chopped our heads clean off!"
The two barely manage to sense the danger and are inches away from getting their head sliced. Though they won't die from it and would still gain the pain and the sensation is unpleasant unless in a fight.
"Oh Father you here? I can see that you need something??"
"Yeah, I thought of bringing you three to the current world I am at to help you grow."
"Is that so? Then I'm going since my blades need some blood and find some worthy opponent."
Unlike the two, he had a calm demeanor knowing how to properly act but still had a ruthless personality who could easily slice a Mid rank True God in a single strike.
He gained the talent in the sword from his Father and had refined it to become his own style. Ryuu even made his own Sect in Dou Di and Wu Dong Qian Kun verse. It focuses primarily on assassination and killing.
"Like these two, tell me what your overall prowess is?"
"I'm at Emperor Soul, My body is Peak Void Immortal and my energy is Mid Realm Lord."
For someone who focuses on the blade, this is the reason why his soul was higher than the two and has a weaker body. He was still stronger than two if they ever spar.
"Show-off!"
"Screw you, Brother!"
Caelum facepalmed at the two battle maniacs while Ryuu remained indifferent.
'Is this how my enemy feels when I'm talking?'
Caelum sighed before giving a proud smile that alright felt jealous.
"You're doing great, young Ryuu!"
"Father, that's cringy."
"...*Cough* Well we are heading tomorrow and don't bring anything else as I won't be taking care of you once we reach the God Domain."
