"Thanks Sis for this" after their full day of training in Qi the two had decided it was time to just rest up in bed and so the two headed straight to bed mainly due to Wukong being exhausted after learning Qi-Manipulation.
....
Soon enough it was morning once again and both Wukong and Lucia were out training, but today Lucia had introduced something new to Wukong, "Wukong you see today we will be using gadgets to improve the intensity of our training and hopefully this will make us reap double the strength with half the effort, here put this golden crown on your head, this crown has no limit to the amount of gravity it can produce, as long as you give it sufficient energy to use."
Seeing this Wukong put on the golden crown upon his head and it fit nicely with his red gi. And when he put it on he could feel that the gravity was set on double the gravity of Earth.
And when he had crowned himself he came crashing down to the ground in a rapid speed and hurt himself due to the immense gravity, when Lucia saw this she began laughing, "Hahahaa" until her eyes became watery as she found Wukong' predicament quite funny.
Soon Wukong had begun crawling on the ground as he was trying to adapt to the gravity and Lucia bent down to see this, but unbeknownst to her was that Wukong was aiming for her crown on her head as he wanted to activate the gravity on hers as well.
"...SWISH!!"
And Wukong had managed to pull her crown down starting the gravity simulation on her causing her to also fall down immediately as she fell she caused the ground to crack slightly as she landed chest first, hurting her breasts in the process.
Finally he had attained revenge and when he saw this Wukong got out of his crawling phase and lied on the ground before laughing his head off in absolute delight and pleasure as he saw that Lucia had also experienced the same humiliation.
"Y-Yo-Youu, just you wait Wukong I will take revenge for this... Yep I've got it the perfect revenge plan: No food for you today, did I mention I was going to make dinosaur steak from the Tyrannosaurus Rex!" As she said she cackled in utmost fury yet also in utmost humour as well.
"Wait-Wait I regret I'm sorry sis, I won't do it again come on don't do this to me I love T-Bone Steak- please no, I can withstand this gravity but not food deprivation!" Said Wukong as he was struggling on the ground as his body wriggled about in frustration.
This merely elicited laughter from his sister, who was in the same predicament as him, and so she laughed so hard she began to cry, she found Wukong' consolations so funny she had a huge grin on her face, until her breasts began hurting due to her landing chest first due to Wukong' sly trick.
....
A week had passed:
A week later Wukong had managed to withstand two times Earth's gravity, and so did Lucia and due to his shock absorber ability his power had spiked forward rapidly going from, 50 Battle Power - - -> 75 Battle Power.
While Lucia's increased from 95 - - -> 110 Battle Power. Meaining she had the same
Battle experts strength as a Level 41 meanwhile Wukong was in the range of a Qi Novice.
But after a week of training in double the earth's gravity Wukong didn't want to subject himself to such inhuman pain anymore so he took a rest, the only actual training he did was to train his ten stances of the "Frost Fists" art, this technique mostly trained the flexibility of his arms to be fast and accurate, hitting the opponents acupuncture to gain the upper hand. Yes learning this technique allowed Wukong to learn of special pressure points within the body that could momentarily freeze someone in battle.
And to maximise his rest he also rested a bit within the Monkey King Realm, though since he had 15 days there he trained in each of his abilities and arts to aid him in battle.
....
"Sis, I don't get it just how did your family get killed, I mean you told me that your father and mother were at the peak of the Bronze Qi realm and that in their time they were quite powerful for youngsters that is, but if this was true how did they head into the otherworld."
Visibly shaken Lucia, didn't know what to say and why Wukong asked this as she thought back to that, moment when she was about 16, the day that her father had been crippled by his opponent in absolute brutality so much so that he couldn't survive the loss of all his energy, and she remembered her brother and mother heading in to attack yet, they were defeated as well.
The opponent so callously killed her loved ones as if nothing happened not a flicker of hesitation or even emotion littered his face as he killed them all like nothing. She remembered when the for turned towards her with his soulless eyes he leaped up and disappeared from the clan never to be seen again.
He had killed everyone that day as he had gone against the clans laws and stole the treasury of the clan but because the clan elder had recently passed no one could have expected this to happen as the for was hiding all his power the whole time and finally butchered everyone to death but her as she hadn't interfered nor attacked him unlike the others.
She still remembered the death glare she was given as it brought a chill to her bone thinking of it. Turning her head to Wukong she saw he was a bit angry for some reason, "Wukong are you alright you seem angry?"
"Sis, haven't I told you I'll always be with you but your face full of sadness is as easy to read as a primary school kids and this is making me feel angry I know I shouldn't have brought it up I'm sorry."
Her face shook again as she combed over his hair, "It's alright Wukong, the killer has long been killed by my hands, I'm no longer the same girl I was when he killed my family."
Hearing this Wukong face reverted back to normal as he gave a simple nod to her. He began focusing on his training again as he wondered what the outside world looked like.
