"Well we're finished for the day." Madara said, as he clasped Jack's hand a pulled him up. "Thank you teacher." Jack replied as he bowed. "No problem, from now on this will happen every day apart from Sunday, you'll know more during class tomorrow." Madara explained.
"Great, then, how do I get back?" Jack asked, not sure how he was gonna get back in a reasonable time. The sun had already set, and darkness had descended.
"Don't worry, didn't I bring you here?" Madara answered as he grabbed the cape of his armor. "Consider this durability training." Madara continued before running to academy, at speeds faster than hypersonic speeds.
'I'll just protect his body with some chakra.' Madara mused, as he defended his student a bit from the impact of the wind. Jack was still getting pounded though as he continually hit into the ground.
'I will get you back for this, porcupine mother fucker!' Jack thought, as they reached the academy. "We've arrived, well I'll be going home, you can make it back to your dorm I assume?" Madara voiced, as Jack nodded.
"Then I'll see you tomorrow." Madara said as his image flashed before disappearing. 'I guess it will take me a while to beat him up.' Jack thought, before walking around the academy and up the steps.
After that he reached his dorm. Inside it wasn't empty this time. Conner was sat on the sofa, his arms bandaged, and Bill was strewn around his bed, completely out of it. "So how was it?" Conner asked as he looked towards Jack.
"Fine, yours?" Jack replied as Conner smiled. "Mine was, great to say the least." Conner said, as he smiled. 'Whitebeard, is great, not only that but he's so strong too, I got really lucky!' Conner thought in happiness as Jack watched him.
"Mhm, whatever, I got Madara." Jack replied, with a bit of disappointment. 'Well at least he taught me how to absorb energy.' Jack thought, before sitting on his bed. "I am going to be training, don't disturb me if possible." Jack stated before sitting on his bed in a lotus position.
"Okay, I think I'll also train." Conner replied before sitting on his bed. At this point Jack had already closed his eye, but if he was looking right now, he would see Conner continually flex and relax his muscles.
A few minutes later Jack was lost in his meditation, and began to collect the energy within his body, as he did so he began to contemplate his powers.
'So if my full power, is my raging power, then what is Meteoric Burst?' He thought to himself as his body continued collecting energy.
As he did so the veins within his body continually filled up, bit, by bit, by bit. 'This, it seems too slow.' Jack contemplated as he meditated. 'I have a 5x booster and Boros genetics, shouldn't this be decently fast? Then again I have no way of telling how old Boros was and how long he trained before he arrived on Earth.' Jack thought as he stopped meditating.
'It feels as if I have to drill through my hands and feet every time. Lets think about this logically, the energy pools around my abdominal eye right? And the veins all seem to connect via my head's eye. So what if, I tried to absorb energy from there?' Jack theorized before getting back into a meditative posture.
'Feel the energy around me, now feel the energy entering my eye, feel it.' He believed as energy began to trickle towards his eye bit by bit, increasing every time, till a stream of energy continually flowed into Jack's body.
This rate of increase, it was at least 20x greater than before. 'This, is amazing.' Jack thought in joy as he watched the stream flow into his body. His strength was increasing much faster than before.
'At this rate within the year, I'll be as strong as Boros if he had all his energy filled!' Jack was delighted by this outcome and he continued to train, not aware of his surroundings, till, morning came.
As he woke up, so did the others, at some point in the evening Kurt had made it back and slept, and now he was completely fine. "Fuck, I am still sore from yesterday." Bill said as he stretched his tired arms.
"My rest was great!" Jack said as he felt his body, he had at least doubled in power from yesterday morning. "I am also a bit drained, but I recover quite well." Conner replied with a smile on his face.
Kurt said nothing though as he looked completely fine. A few seconds later, Jack pinched his nose. "Guys we smell, have any of us taken a shower or anything?" Jack asked, as all of them shook their heads.
"Okay, well we've got about half an hour, if we all take a shower quickly we'll be fine." Conner said, as he gazed at all of them. "So who's first?" He asked.
"Me!" "Me!" Bill and Jack shouted one after the other. "What do you mean you? I had the idea." Jack declared as he gazed at Bill furiously. Soon an argument ensued, and Conner just moved towards Kurt.
"With how long they're going to take, you can shower first." Conner whispered as Kurt nodded. "But do we have any soaps or anything?" Kurt asked, hearing this Conner was stumped.
They then looked inside the bathroom and realized it was empty. "Damn it." Conner said as they walked out of the bathroom.
"So guys, there is no soap to shower anyway." Conner voiced as he rubbed his head. Hearing this, Bill and Jack both stopped arguing. "Look at you, having the idea and then we have no soap, shameful!" Bill said as he glanced at Jack in disdain.
"Y-You, fuck off!" Jack said as he went to the door. "I am going to see if they serve breakfast." He continued before leaving. "Hmph! He thinks he can hog all the breakfast to himself?" Bill replied as he went after Jack.
'What a, wait is there a word for that?' Conner thought as he gazed at Kurt. "I guess we just follow them?" Conner said. "Ya, I don't mind some breakfast." He replied as he grabbed the sword from his bed, and walked out with Conner.
