A Hydrogen Atom from the Start: I Become a God Through Fusion

When other people open their eyes, they find gold or diamonds. When I open mine, I find hydrogen. The most abundant element in the universe, and the most useless. My body is soft and falls apart at the slightest touch. I can't win a fight, and I can't even hold on to my own electrons. The whole hall agrees I'm a walking time bomb, so they sent me off to write the universally ignored Element Encyclopedia. Every day, people treat me like air. No one knows that fusion is hidden inside this ridiculous, feeble body. On the Night of the Half-Life, the Imaginary Celestials came through cracks in the void. They hunt down elemental cores, but never kill anyone. What they're trying to assemble is an ultimate holy body. Once it's complete, the universe will reach heat death ahead of schedule. One senior after another disappears. This good-for-nothing keeps trading his life for others, again and again, dragging back companions who should have been erased. What are you doing? Keep this up and you'll be the first to disappear. Shut up! Just let me do something useful for once, okay? From then on, the fiery-tempered heroine, Oxygen, who had always shielded me, began to look at me differently. Mercury, the lonely night sentinel, so toxic that no one dared approach, lowered her guard for the first time. Even the temple's Law Venerable began to take another look at me, the useless one. They think my own constitution will eventually blow me to pieces. They don't know. I'm no good-for-nothing. I just haven't reached the point of burning yet. At the moment of death, chain fusion ignited. The fire consumed me, but its light shone on everyone.
