He carefully stepped around the scattered wires on the floor and soon found the part Bulma needed.
For the next half month, Tang Yangbing assisted Bulma with the construction of the time machine almost around the clock.
They worked day and night without rest, and the laboratory lights often remained on deep into the night.
Tang Yangbing handled the heavy lifting and calibrated the mechanical arms, while Bulma focused on assembling the intricate circuit boards and energy core.
They went through several near-explosions along the way, but their seamless cooperation always pulled them through safely.
Finally, on a star-filled night, Bulma pressed the final button.
With a low hum, a dreamlike blue glow began flowing across the surface of the time machine.
The sleek machine resembled an enormous water droplet, its surface covered in countless fine energy patterns that shimmered with a mysterious light beneath the laboratory lamps.
"It's finished." Bulma let out a soft breath and wiped the sweat from her brow with the back of her hand.
She walked over to the time machine and stroked its smooth shell, then looked at Tang Yangbing with a complicated expression. "This time machine should be able to send you back twenty years. Good luck." Her voice was quiet, yet carried an indescribable loneliness. "Once you go back, don't come here again. There's... nothing left here worth holding on to."
Tang Yangbing opened his mouth, wanting to say something, only to find that his throat seemed blocked by something.
Looking at Bulma's somewhat haggard face, he recalled the days they had spent fighting side by side, and an indescribable emotion surged through him.
For a while, only the hum of the machinery remained in the laboratory, and the air was filled with a faint sense of parting sorrow.
In that silent moment, Bulma suddenly seemed to remember something and added, "Oh, right. The time machine may not have enough fuel. Materials were limited, so I could only get the bare minimum of antimatter fuel. Whether it can get you back twenty years on time will depend on your luck." Tang Yangbing's mouth twitched slightly at her words.
You've got to be kidding me, right?
A trip through time actually depended on luck?
If the fuel ran out halfway through, who knew what time and space he would get thrown into?
He could practically see the tragic image of himself trapped in a rift in time and space.
But things had already come this far. There was no turning back.
Tang Yangbing took a deep breath and walked toward the time machine emanating its blue glow.
The hatch slowly opened, revealing precision control panels within that gleamed enticingly.
He knew that a journey through time and space, one tied to the fate of the universe, was about to begin.
In the deep, boundless universe, stars glittered like diamonds as a colossal spacecraft, vast enough to blot out the sky, tore through space at a terrifying speed. Its hull was covered in cold metal armor that reflected a chilling gleam beneath the light of the stars.
Like a slumbering giant beast, it sped toward the blue planet slowly rotating in the distance—Earth.
Inside the spacecraft, the control room was as spacious as a plaza, its surroundings filled with control panels glowing dim blue and holographic projections.
The three great leaders of the Frost Demon clan—King Cold, Kuriza, and Frieza—stood before the main console.
King Cold wore dark golden armor, his crimson cape fluttering despite the absence of wind. Elegantly swirling a goblet in his hand, he watched the blood-red wine ripple within, reflecting his cold and arrogant face.
His gaze pierced through the viewport and settled on the gradually enlarging blue planet, a cruel curve lifting at the corner of his lips.
"Father, that is Earth." Frieza's voice was icy and piercing, carrying barely restrained killing intent.
Though he had returned to his final form, his body was covered in grotesque mechanical patches, metal and flesh intertwined as though he were a killing machine forcibly pieced back together.
Revenge burned in his eyes, and his scarlet lips moved slightly. "This time, I'll crush those damned Saiyan monkeys into cosmic dust!"
Kuriza stood beside him with his arms folded, his four cold eyes narrowing slightly with contempt and mockery.
"Saiyans who pushed you to such a state? You've made me rather curious." He snorted softly, his silver-white tail slowly swaying behind him. "If it weren't for the family's honor, insects in such a remote star system wouldn't be worth my personal intervention."
Frieza abruptly turned his head, his mechanical joints producing a harsh grinding sound. "My dear brother, you'll soon witness for yourself how those vile Saiyan monkeys defiled our glory with their filthy tricks!"
His voice trembled with rage as his sharp nails dug deeply into his palms. "Especially that Son Goku... I swear I'll tear apart every inch of his flesh and drink every drop of his blood!"
King Cold slowly drained the red wine in his glass, then casually crushed the crystal goblet into powder. "Super Saiyans..." His deep voice echoed through the control room, carrying suffocating pressure. "Such a bloodline should never exist and must be completely eradicated. Destroying this planet would be effortless, but only by crushing their bones with our own hands can we quell the fury of the Frost Demon clan."
Frieza gave a savage grin, and terrifying purple energy erupted around him. The mechanical patches on his body buzzed under the impact of that power.
"Father is right! After this period of enhancement and modification, our power is no longer what it once was. In this universe, there is no living creature left capable of standing against us! Let Earth become the Saiyans' final grave!"
Outside the viewport, Earth's outline became ever clearer, its azure oceans and emerald continents woven into a beautiful tapestry.
Yet beneath that peaceful scene, a bloody storm destined to sweep across the stars was silently drawing near.
Frieza's tail, covered in deep-purple scales, slowly swayed behind him like a venomous snake poised to strike, every movement carrying a heart-pounding rhythm.
His sinister gaze swept over the holographic displays in the control room. A cruel smile curled across his lips as he spoke in a low voice brimming with killing intent. "Right in front of that ignorant wild monkey, I'll personally crush every last insect on Earth. I'll make him watch helplessly as they all howl in despair and slowly die in endless agony!"
Kuriza stood nearby with his arms folded, undisguised pleasure appearing on a face similar to Frieza's but even more vicious.
He narrowed his scarlet eyes slightly, as if he could already picture rivers of blood, his voice carrying an almost pathological satisfaction. "Watching the weak struggle to survive, hearing their screams before death—that is the most beautiful symphony in the universe." Perhaps due to some unknown disturbance in time and space, the river of history had veered from its original course at this moment.
The spacecraft that should have carried only Frieza and King Cold on their journey of revenge now had an additional passenger even more terrifying—the one known as the "Ice Demon," Kuriza, who gazed at the gradually enlarging blue planet beyond the viewport with a bloodthirsty smile.
Accompanied by a deafening roar, the silver-gray spacecraft crashed heavily into the ground like a meteor.
A violent shockwave spread outward from the landing site, kicking up dust that filled the sky as withered grass and shattered stones whirled wildly in the raging air currents.
The spacecraft's hull reflected a cold gleam in the sunlight. Before its hatch had even opened, a suffocating pressure already blanketed the entire region as though it were tangible.
At the far end of the barren plain, Earth's warriors, led by Son Gohan, were already waiting in full battle formation.
Krillin clenched his fists, fine beads of sweat forming at his temples. Tien Shinhan's three eyes were all fixed on the distant spacecraft, his muscles taut as a drawn bow. Yamcha unconsciously swallowed, his legs trembling slightly. Piccolo's green skin seemed especially grim beneath the sunlight. And though Vegeta, standing behind the others with his arms folded, put on a composed front, his tightly pressed lips and flickering gaze betrayed the turmoil in his heart.
"This is... unbelievable." Yamcha's voice shook visibly as he stared at the spacecraft radiating an ominous presence, sensing the three bottomless, abyss-like energies within. "On Namek... you fought monsters like these?"
