Since the end of the Battle of Planet Tuffle and the resolution of the Black Star Dragon Ball crisis.
Earth—or rather, two Earths in different timelines—are both experiencing a rare period of peace.
For Son Satoshi, this period was both fulfilling and "busy".
He is like a ferryman traversing the river of time, living a "double life".
West City, Capsule Corp ( Main Timeline ).
The morning sun shines on the huge hemispherical building, and the fountain in the garden reflects a rainbow of colors.
Good morning, honey.
Bulma, dressed in a loose silk nightgown, curled up lazily in bed like a cat, watching Son Satoshi emerge from his wash-up routine, her face flushed with happiness.
On the other side of the bed, the blonde Android 18 was fixing her hair in front of the mirror. When she saw Son Satoshi walking over in the mirror, a faint smile unconsciously appeared on her lips.
"Good morning, darling. Are we going 'over there' again today?"
Android 18 asked, his tone carrying a hint of concern, but not much jealousy.
In this family, or rather, in this family maintained by Son Satoshi's absolute strength and charisma, there were no melodramatic palace intrigues.
Bulma's intelligence and tolerance, and Android 18's aloofness and devotion, are perfectly balanced by Son Satoshi's "powerful" physique and meticulous care.
"Um."
Son Satoshi walked over and lightly kissed each of them on the forehead.
" Goku over there is a worthy opponent. Sparring with him will allow me to see some things I've overlooked before."
"What a martial arts fanatic."
Bulma gave him a reproachful look.
"Honey, you're already the strongest, yet you're still pushing yourself so hard."
"Martial arts have no limits."
Son Satoshi smiled.
"Moreover, in order to protect you, I must always remain at the forefront of the battle."
After a brief moment of tenderness, Son Satoshi went to the backyard of the Capsule Corp.
There is a clearing here specially set aside for him, where no one will disturb him.
"Call..."
Son Satoshi adjusted his breathing and gently placed two fingers between his eyebrows.
The God Ki within his body began to surge, resonating with the [ Rabbit Talisman ] that had seeped into the depths of his soul.
Time-space jump initiated.
"Whoosh!"
With a distortion in space, his figure vanished into thin air.
The next second.
GT Timeline, Mount Paozu, Son Family Old Residence.
Although the timeline here is more than a decade later than the Main Timeline, the scenery of this mountain forest has remained almost unchanged.
"Hey! Bro! You're here!"
A boy who looked only eleven or twelve years old was hanging upside down in a tree, eating an apple. When he saw Son Satoshi appear, he immediately jumped down excitedly.
It is GT Goku after he shrunk.
" Goku, you seem to be in good spirits today."
Son Satoshi looked at the "younger brother" in front of him, a hint of admiration flashing in his eyes.
Although he looks like a child, the aura he possesses is as steady, profound, and unfathomable as steel that has been forged through countless trials.
This is why Son Satoshi often chooses to travel through time and space to spar with GT Goku.
In the Main Timeline (the original Dragon Ball Super ), Goku's mastery of basic martial arts is still inferior to that of GT Goku, who has experienced countless life-and-death battles and lived for more than a decade longer.
In its normal state, GT Goku is a true "monster".
That was to cultivate the Saiyan's mortal body to a level where it could withstand anything.
During the Super 17 arc, he easily outmaneuvered Cell and Frieza in Hell using only his normal state.
"Hehe! Because I feel like I'm going to learn something new today!"
GT Goku finished the apple in a few bites, tossed it aside, and struck the classic Turtle Hermit Style starting stance.
"Brother, I spent all night figuring out your ' Deflection Technique ' move yesterday. I'm going to show you how to break it today!"
"OK."
Son Satoshi also took off his jacket, revealing a black, tight-fitting training suit underneath.
"Then let me see how much you've improved."
"Haa!"
Without any unnecessary words, the two figures collided instantly.
The wind howled as the fist struck, its energy surging and spreading.
Neither of them transformed into Super Saiyan; they were simply engaging in a pure martial arts exchange in their normal state.
Even so, the aftershocks from each collision create visible ripples in the surrounding air.
This high-intensity combat training is the best whetstone for Son Satoshi.
It helped Son Satoshi gradually solidify the God Ki within his body, allowing it to settle into every cell.
Three months later.
Main Timeline, West City, late at night.
The moon was bright, the stars were few, and all was quiet.
The bustling city has fallen asleep, and the residential area of Capsule Corp has long been dark.
However, deep underground at the Capsule Corp, in the specially modified Gravity Training Chamber, the lights were on all the time.
"Buzzing--"
The enormous Gravity Generator was running at full power, emitting a deep, suppressed roar.
The red alarm light flashed wildly on the control panel, and the numbers on the display were alarming: 10,000 times.
Ten thousand times the force of gravity!
What does this mean?
Ordinary Earth rocks would instantly crumble into powder under this gravity; steel would be directly crushed into a disc.
Even Frieza in his Final Form back then would probably be unable to move a single finger under this gravity.
However.
In the center of the training room.
A black-haired young man, shirtless and wearing loose-fitting workout pants, stood there quietly.
Son Satoshi.
Faced with this terrifying gravity powerful enough to crush mountains, his body not only did not bend in the slightest, but instead appeared unusually upright and relaxed.
Sweat dripped down his strong muscles, only to be crushed by gravity the moment he hit the ground.
"Drop--"
" Simulation Combat System activated. Difficulty level: Highest. Target locked: Son Satoshi."
As the mechanical electronic sound rang out.
Hundreds of dark gun barrels simultaneously emerged from the walls surrounding the training room.
In addition, dozens of high-tech Floating Cannon, each only the size of a fist, were suspended in the air at extremely high speeds.
"Start."
Son Satoshi did not open his eyes.
He simply uttered those two words.
Whoosh whoosh whoosh whoosh----!!!!!
In an instant.
The entire training room was transformed into a sea of lasers.
Countless high-energy laser beams, with irregular trajectories, shot towards Son Satoshi in the center from all directions, without any blind spots.
These lasers travel at the speed of light, but under the special force field interference of the Gravity Chamber, their trajectories become even more unpredictable.
Faced with this relentless attack that would surely result in certain death.
Son Satoshi a move.
More accurately, it was his body that moved on its own.
