One Piece - I Am A Different Luffy! - Chapter 518 - 516 - The Arrival of Those Bound to the Past.

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!

Lu Yu came to a strange beast-monitoring world where evil gods peeped in and ancient taboos revived from the depths of time.

In this world, birds, beasts, mountains, rivers, and even elements can be born and turned into pet beasts spiritually. Among them, the powerful ones themselves are ecological niches, radiating out ecological secrets such as the secret realm of the underworld, the kingdom of bones, the lair of succubi, and the kingdom of heavenly trees, giving birth to countless Dependents.

The beast master makes a contract with the beast, cultivates it, and controls the spirituality.

After witnessing the [Forbidden Sun] incident, Lu Yu gained the ability to extract materials from all things in the world and edit [Secret Food].

Evolve the secret food, with [Broken Twilight World] + [Ancient Dragon Dead Egg] = Final Banquet, after the royal beast eats it, it evolves into the Final Dragon God, the twilight realm erodes the world, and becomes the God of Doomsday.

The skill secret food is the skill of controlling beasts to plunder all things, to become omniscient and omnipotent, to sacrifice secret food to intercept taboo time, to sacrifice ancient existence, and to blaspheme the gods.

And his style of painting the beast has also become weird.

There is the dream of weaving all living beings, the spider shadow that entwines the ancient dragon with spider silk, and the Crimson Lord that pollutes the multiverse, and there is the Devourer of Worlds that feeds on the world…

In this regard, he explained: “My beast masters are just a little weird, they are really not evil gods!”
