Teleporting behind the invader via the flying thunder God seal he placed on his back, sage mode Minato dodged the three tails and slashed his kunai towards the Invaders neck.
Without even attempting to dodge, a pitch black straight sword suddenly manifested behind the invader, blocking Minato's deadly attack! As the sword began to fall, one of the Invaders tail dexterously grabbed the blade and furiously stabbed Minato directly into heart, only for a poof of smoke to appear and a desert tortoises taking Minato's place!
Dropping his kunai to the ground, Minato rushed forward and fought using his bare hand, launching a straight left jab at the invader who tried to dodge. Despite foreseeing the attack and jumping back, Minato's fist that was a half foot away somehow seemed to connect!
This was the signature Taijutsu of the Sage Frogs, allowing one to extending their Taijutsu attack range via Nature Chakra! Not only did this Taijutsu extend their attack range, it also was invisible to those unable to use Nature Chakra even if they had a rinnegan!
While dodging the invaders greatsword and tail attacks with teleportation, Minato launched a series of quick combo attacks that pierced through the Invaders foresight, turning the one sided fight into the opposite direction! The invaders was being pummelled from all sides by the constantly teleporting Ninja and his invisible attacks.
Despite his attacks connecting, Minato saw the invader unfazed face and watched as his wounds regenerated faster than the onslaught of punches he rained down, knowing he had to deal much more damage than just punches!
The invader wasn't just brawn he had some brains, while he couldnt sense Chakra he knew that teleporting had to be very energy draining so he just played defensive and conserved his energy.
As the flowing current of punches rains down upon the invader, suddenly a ball of blue energy appeared instantaneously in Minatos hand! The rasengan looked as if it was flickering out of existence just by being close to the invader, but it resisted the Invaders negation!
Minato realized that the invaders ability didn't erase his chakra out of existence, but instead defused it and turned the jutsu back into ambient nature chakra. This was the reason why his sage jutsu imbued with nature chakra, although weakened, could resist the invaders negation ability!
"Sage art: Rasengan!"
Slamming the blue ball if chakra into the greatsword of the Demon like invader, Minato sent the invader flying from the impact. Although the strength of the sage art rasengan was much weaker, he could now utilize his chakra!
Despite this turnaround, Minato was stone faced as he panted heavily and his mind was racing a mile a minute. From what he had seen, Minato doubted his Rasengan could permanently injured the Invader even if it landed directly into his body, let alone landing on his greatsword.
'Should I attempt adding elemental chakra into the rasengan? I nearly killed myself from the previous attempt, but if I overload the jutsu with a large amount of chakra and then add element, the resulting explosion should eclipse the rasengan multiple times over.... I doubt I'll have enough chakra to teleport away...."
Minato resolved himself for death, he believed Chiba's words and thought this Invader was a hitman from the future intent on destroying humanity. Just as he began to focus on his elemental rasengan , he suddenly felt a powerful tug backwards as he flew next to Chiba.
Feeling the heat radiating off of the young boy and seeing the blood and chakra evaporating from his body, Minato couldn't help but compare Chibas current state to the technique of his only student's rival, Might Guy!
"Chiba your-" "it's fine. Just hold onto me and teleport us away, I need to survive long enough to undo my attack before...it destroys the entire planet."
Looking at the dying one armed and one legged boy, Minato felt ashamed but nodded. Placing his hand upon his red back, Minato grimaced in pain from the heat but didn't back away as he used his chakra to remain stuck to the boys back when the world suddenly went dark.
From space, a massive ball of space debri began entering the planets at insane speeds.
"How many times must I show you how futile your strength is boy! No matter how many rocks you throw at me or how badly you injure me, I'll just keep coming back no matter how damaged!"
Strained face, Chiba couldn't spare a single moment to answer him as all of the wounds on his body began to open up, too preoccupied to stop the bleeding.
The invader took a step forward to attack before stopping as moonlight washed over the cold desert once again! He watched as the massive meteor began to condense at rapid speed!
It went from from blocking out the moon to suddenly being the size of a house in a few second, continuing to shrink even further! The Invader didnt know what was happening and didnt know how to react.
As the now marble sized meteor was just ten feet above them, it condensed even further into nothingness and disappeared as Chiba collapsed to the ground, smiling happily.
Unbeknownst to the boy, he had forced his devil fruit awakening with his insanely powerful physique that the 8th gate had granted him!
The victorious smile on the boys face unnerved the invader and felt the overwhelming urge to kill him immediately but stopped as he saw something strange.
The boys missing arm and shattered limbs were still bleeding heavily, but the blood stopped falling to the ground! He watched as the blood lifted up from his bleeding wounds and into the air where the Meteorite disappeared...
It was only at this moment that he realized small amounts of sand began to go against the planets gravity and flew into the air as well...
A horrifying look overtook the invaders smug face as he watched more sand quickly fly into the air, the speed began to pick up and he watched as an incredibly tiny ball of pure blackness appeared in the sky! It sucked up everything from blood and sand, to even the Moonlight and was growing larger!
"You! What have you done!" The wings on the invaders back began to flap desperately to get away, only to be slammed back down to the ground as purple ring of gravity appeared above him.
With blood pouring out of his red mouth and nose, Chiba's face couldn't contain his smug grin as he used every ounce of will power amd strength to hold the invader down.
"You're too strong for me to actually defeat in battle, so i had to call in some help from Nature!" The invader turned horrified as he realized Chiba had just created a black hole that would suck in the entire planet!
