Douluo Dalu 2: The True God King - Chapter 172: [DD2]:

“There is no greater sorrow than to recall happiness in times of misery.” — Dante AlighieriThis is a quote that dictates my life perfectly. Ever since I was a young boy, I enjoyed playing games, so much so that I carried that passion even into my sophomore years, all the way to my death.My story in life isn't all that tragic compared to the more unfortunate out there. I am your typical game creator. I made indie games and visual novels for a living.Naturally, being out of passion and an unknown solo developer, I tried my best to get my work out there, working additional jobs, doing side hustles, both online and locally, all just to survive, and all just to sponsor my work.However, in a world where competition is vast in the game industry, everything I make only ends up at the bottom rank. Because of this, I never gave up, but as I went into my thirties, this passion of mine separated me from my family.These days they don't even talk to me anymore. Depressed, alone, and on the verge of a mental breakdown, I lost all hope, and it didn't help that I had two months of rent due and bills that needed to be paid.But all that changed one night when I got a mysterious message that suddenly appeared on my laptop screen:“You who despair! Would you like a second chance at life? If yes click and offer up your life worth's negativity to me, if no forget this message completely!?”At that time, I clicked Yes by accident.But as the message said, I died due to a heart attack and reincarnated into the World of Purgatory. This was the greatest mistake of my life, as it changed it forever. However in this world I came with the power called the Administrator — a power I gained as a newborn Negative Spirit.With this power I exist as an Entity of Dreams, but even without a physical body, I was determined to make my wish come true: to be a game creator. But unlike other devs, my dreams are different. I can create scenarios in the dreams of men, forcing them to play my game. If they win, they walk out of here as an Awakened Spirit Warrior; however, if I win, the abilities they would have gained in my trials go to me. In this game of mine, anything could be wagered. In reality I have nothing to lose as the Administrator. But to the players, what they wager could be a matter of life or death.

Jacob Steve, an Old Man, died at 116 after living a whole life.

But Jacob always had a dark side, which he always suppressed and hid from others.
However, in the later years of his life, when death was inevitable, he understood there wasn't any point in having wealth, knowledge, or desires if you couldn't have a life to enjoy them.

He became obsessed with fabled immortality and devoted his reaming life to extending his fleeting lifespan, but just like any other failed.

However, he mysteriously got another chance at life and found a way that led to fabled immortality.
But he was also forewarned that the way led to it was filled with blood and darkness!

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!
