Fulfilling the Promise.

For the next several days, the glow of Lab Eterna never dimmed, reflecting the relentless pace at which Jack and his team worked. The breakthrough hunger pill was already a marvel, but the immortality serum was an entirely different frontier. Jack's ambition burned brighter with each passing hour, his focus unyielding as he delved deeper into the mysteries of life itself.

While the ultimate goal of creating a serum for true immortality remained in the distance, Jack knew he had a promise to fulfill. Dev Swami, the influential and enigmatic investor who had supported Jack's dreams, had been promised a gift—50 more years of life. A task that daunting might have shaken others, but for Jack, it was simply another challenge to overcome.
