After Draining the Strongest, I Became the Strongest!

One day, you transmigrate, and the transmigration god asks what kind of golden finger you want.

You ask, with a faint air of despair: Can I get something for nothing?

The transmigration god says: Pick something else.

You ask again: Then can I just sit back and enjoy the benefits?

The transmigration god: ...Try asking for something a little more positive.

You say: I want to get twice the results with half the effort.

The transmigration god is out of options: Are you seriously just looking for synonyms?

Then it kicks you into another world.

Your golden finger is: a dodder vine.

Congratulations! As long as you find a Host, you can get something for nothing, sit back and enjoy the benefits, and get twice the results with half the effort!

But because your parasitic abilities are so powerful, a weak Host will die soon after you latch on.

So, the Hosts you choose are...

The strongest demon in Heian-kyo, Ryomen Sukuna; the strongest modern sorcerer, Gojo Satoru; the God of Shinobi, Senju Hashirama; the Madara of the Ninja World, Uchiha Madara...

You think that from here on, you'll have to fawn over them, swallow your grievances, and grovel... But as a plant, you have unlimited regenerative abilities.

You: Huh?

And then you rush over and slap Ryomen Sukuna across the face (not really).

Theme: With hard work, you can build a beautiful life!
