Apocalyptic+Collect+Synthesize
Traveling through the apocalypse, he awakened the most rubbish talent in the power system. He carried bricks and picked up rubbish every day, and was treated like an ant by the elite warriors.
But they don't know...
When they were fighting for a fine steel knife, I used two pieces of scrap metal to synthesize the Hundred Refining Divine Weapon.
When they spent all their money on a healing elixir, I synthesized a marrow-cleansing elixir from two weeds.
When they laughed at me for knowing only exploration, I had already used the materials I found to synthesize the world-destroying mecha, and by the way, I turned their goddess captain into my exclusive bodyguard.
Don't ask me who I am, I'm just an ordinary "little transparent".
