I'm in Marvel

Traveling through Marvel, Russell awakens his attribute panel, and can improve infinitely by absorbing energy.
Talent 1 [Energy Absorption]: Can absorb any energy and convert it into [Lifespan] (attribute points).
Talent 2 [Attribute Transfer]: [Lifespan] can be converted into [Constitution], [Perception], and [Spirit].
Just when Russell thought that his fate was numerical crushing and becoming a one-punch man, he found that there was something wrong with his talent 1 [Energy Absorption].
Light energy, electrical energy, thermal energy, kinetic energy... and various magical energies.
Under the guidance of Master Ancient One, Russell began to harm the demons of various dimensions.
Russell: "Mephisto, I forgot to collect the interest on the last compensation. Let me settle it."
Russell: "Beast? Just a primitive demon, watch me refine it in an instant."
Russell: "Dormammu, I'm here to negotiate."
... And e=mc^2, mass can also be converted into energy... Multiverse, you smell so good.
