"COME ON!!!" Luffy screamed with ferociousness as he met with Kronos's flame attack. BOOM! The Earth beneath him shattered as Luffy's body was buried into it.
At this moment Ace and Sabo appeared on both sides of Kronos lifting their iron pipes towards the sky before swinging down with a great swiftness. Kronos suddenly felt the oxygen particles within his area shift, obviously disturbed.
Sensing this, it caused a swift reaction from Kronos as he tucked both his fists in at his abdomen taking a quick horse stance before sending out two flaming fists that felt as though they had spawned from the depths of hell.
A bright blue hue overtook the two boys who were unfortunate enough to receive the hellish attack. "Puhhh!!!" Their breathless groans came out in synchronization as Kronos's blue fists dug into their guts.
Bang!! Their bodies shot back like bullets once again before slamming into nearby trees. "A-Ace, SABO!!!" At this moment Luffy forced himself out of the hole whilst bearing the pain of several fractured bones with gritted teeth.
"FUCK, WE'RE NOT GONNA LOSE TO YOU FOREVER KRONOS!!" Luffy's blooded face was twisted into a maniacal one yet his eyes drowned with determination as he threw such a bold remark towards Kronos.
At this moment Kronos understood that Luffy had forgotten the purpose of this match and so did he. Coming to this realization Kronos dispersed his Blue Flames and gave a low sigh whilst looking at the damage he had caused upon his brother, his friends and the beautiful land.
Soon however Kronos would come to regret lowering his guard at this moment as a small fist came flying towards his face. With its sudden appearance Kronos didn't have time to activate his flames nor did he have time to move out of the way.
With that being realized Kronos stood there glued to the ground taking the full swing of the punch. Bang! Kronos was then abruptly seen flying backwards before slamming into the ground.
"Damn.." Kronos spat under his breath. He tried to get up but before he could Luffy pounced on him and started pounding his fists into his face. After twenty minutes of making Kronos his personal punching bag, Luffy noticed that his punches were barely doing anything to his brother.
In the end he got tired and frustrated and rolled off Kronos laying at the side of him. "Hah…. happy?" Kronos then broke the built up silence with a sarcastic ass question whilst even revealing a face of pure mockery.
Luffy glimpsed over and scoffed whilst snarling angrily at his brother. "Shut up. You better apologize and train Ace and Sabo with your best!" Kronos rolled his eyes before getting up onto his feet. "Of course I would, you idiot." He said as he suddenly tossed Luffy over his shoulder as if he was a rag doll gaining him a small grunt of pain from Luffy.
"Let's go get them and head back home so grandpa could patch them up." Kronos then walked towards Ace and Sabo. Reaching them he woke them up taking the most damaged of the two boys which was Sabo and throwing him over his other shoulder before telling Ace to climb onto his back.
Thanks to their height difference it was quite easy for them to coordinate with each other and pull off the action Kronos had executed just now. With them all being carried by him he headed towards his home.
It took an hour for them to arrive and boy oh boy did they receive a scolding from Garp. Kronos received far worse than them all as he was the perturpeter. Garp decided to punish him physically.
Two heavy fists landed on the boy's head raising two comically large bumps on each side. Kronos cursed under his breath while he winced in pain. Taking his two punches knowing he deserved it he allowed Garp to see after the boys before he went off into the distance earning him the displeased words of Garp once again.
"OY! YOU LITTLE BRAT COME BACK HERE AND LOOK AFTER YOUR BROTHER AND FRIENDS!" However Kronos just lifted his right arm and waved, walking away with a rather nonchalant attitude, shocking Garp as he knew how much Kronos cared about Luffy.
However this Kronos had no sort of attachment to Luffy and the boys so it was rather difficult for him to care so suddenly though he would be lying if he said that Luffy, Ace and Sabo weren't growing onto him.
As Kronos continued on his little walk he gathered his current thoughts and re-evaluated himself. He came to a standard understanding that his strength was far stronger than kids his age but was weak when compared to real strength.
It was impressive in the least. With that being settled, Kronos then went on to rearrange his schedule and put into place a heavy intense training routine.
He took the logic of being an otherworldly being with a body far more stronger than an average earthling's own and decided to push beyond muscle failure for his entire body. That was the plan.
And with that being the plan he delayed no further as he settled himself in a rather tall grassy field deep within the forest, starting his intense training immediately.
He looked around the area and gathered the heaviest of rocks he could find. There were only three and with the smallest one which was actually two meters in height, he could barely lift it over his chest.
The other two which were coincidentally next to each other were impossibly heavy for the boy to carry so he decided to make things easy and just move the one which he could only barely move and put it next to the two titanic like boulders.
With the current boulder Kronos took on a horse stance before forcefully gripping it with his slightly rough hands. Then, using all of his current strength he lifted it as veins began to bulge all over his arms and while his face turned blood red.
Lifting it only slightly above his lower chest he threw it into the air only managing to get it slightly over his head before having it drop its full weight of its entire being back into his arms.
As he caught it his feet sunk into the grassy field and even caused the dirt hidden underneath to explode out. At this moment veins even bulged on his neck and face as his teeth were suddenly gritted together with a frothy line of saliva streaming out of his mouth.
Under all this pressure and strain he still managed however, to mutter a single thing, "1…!!!!!" His first rep was then counted. Soon he continued to repeat his earlier actions while vigorously counting his reps. "2! 3! 4! 5! 6!"
And like so it continued before he completely lost all strength from his arms to his shoulders and even his upper back. His legs felt sore as well but he didn't even consider all of these things only focusing on his now determined highest rep number for this exercise.
The number was 18. Yes, such a low yet high number, however, Kronos did not even consider the quantity of his reps as he sat on the ground gasping for air, drenched in sweat. He looked back to his form and quality of technique as he scolded himself internally.
If he had not ran out of strength and stopped at 18 he would have surely injured himself. Looking at his form he knew that the reason it was so incorrect was because he lacked strength.
And, as he lacked strength his arms couldn't take the load alone which was why his shoulders and upper back were strongly playing a role as he did the exercise.
Now, even if he had the strength, his shoulders and upper back were still going to get a workout from him doing the exercise but it wouldn't be as major as its current effect which made it so easy for Kronos to discern the issue with his form.
Taking a 30 minutes rest break and finally feeling that the burning sensation in his arms, shoulders, upper back and legs had retreated he decided that he won't train with these three massive boulders as of yet. He got up and walked around in search of a rock that was as big as a toddler.
Finding what he searched for he put to test a theory he had thought of in his previous life and that he had mentioned a bit earlier.
Although he didn't know if the current world he was in was an anime world, he still decided to test his theory from his previous life.
Looking back to how Goku, Killua and other anime characters went through hellish training that would most definitely kill the average Earthling from his previous world, the anime characters who trained with such intensity not only survived but also had their physical prowess rise greatly along with their physical body's capabilities and limit.
He thorised whether it was just plot armor or the anime characters' body that was far more versatile and adaptive than his previous world's people.
He lay on his back with his legs now balancing the toddler sized rock at the soul of his feet. He hesitated a bit but just ignored his hesitation before abruptly launching the boulder into the air and swiftly turning over quicking getting into a push up position.
This would most definitely be the most idiotic and maniacal method of training Kronos might have executed as of now.
Feeling the heaviness of the boulder before it even touched his back Kronos gritted his teeth and readied himself for unbearable pain. BAM As it came slamming down onto his back Kronos could have sworn he heard the sounds of bones being snapped.
His eyes sprung open intensely as he suddenly began swallowing the oxygen of the surrounding area through his pores.
As he circulated the oxygen within him he suddenly felt himself being able to breathe better in his current situation while he felt his back relieve itself of some of the pain.
Remaining in a pushup position for a few seconds he then proceeded to do pushups albeit slightly struggling as he counted his reps.
''1, 2, 3, 4, 5…..'' He counted as he continued his exercise. Soon he reached the number twenty five. There he stopped and tilted his body slightly to the right allowing the boulder to slide off and fall upon the ground.
He was then seen gasping for air as he allowed himself a five minutes rest, proceeding to then sit in a lotus position. His thoughts slowly began to drift. 'I've completed the first set, three more sets to go before moving onto the next exercise. But that aside, I had no idea that I could relieve the pain of heavy impacts from just circulating oxygen throughout my body. Interesting…It kinda reminds of those breathing methods from Demon Slayer. Wait..what if I was to actually implement a proper breathing method for my ability to manipulate and form oxygen? Would the effect it had earlier become even greater? Let's give it a go right now actually.'
Kronos then began to once again draw in the oxygen within the area as he inhaled properly through his nose and exhaled through his mouth. Soon the oxygen began to flow throughout his body in a structured manner affecting his flow of blood whilst greatly impacting his bodily reactions.
He felt as though he was merging with the oxygen surrounding him as the pain from his back completely vanished even feeling as though his entire back, arms, shoulders and legs recovered and gained new strength.
Kronos jumped around within his heart as he enjoyed the wonders brought by his ability. He soon went back to training as this time he decided to maintain the breathing method while doing the exercise.
This time he managed to perform the exercise faster than before as he quickly hit the 25 rep mark he previously struggled to reach. Considering his current achievement he decided to do more in this one set as he struggled at a new rep number of 50.
But he knew that he could still do more. He then proceeded to continue until he felt as though his triceps and chest were going to fall off stopping at an incredible number of 75. He once again tilted and let the rock fall onto the ground before once again getting into his previous lotus position whilst feeling an abrupt rush of power within.
'Hahaha! At my current speed of improvement there is no lie in saying that I'm this world's beloved MC!' Kronos shamefully proclaimed himself as, feeling loved by the world and by that 'being' for having such incredible improvement speed. Unbeknownst to Kronos however, he would soon come to regret saying such words.
