High Alchemy

The hydrogen bomb was a second-generation nuclear weapon that comprised two stages, using fission power to trigger nuclear fusion. As such, its explosive power was hundreds to thousands of times stronger than an atomic bomb, which solely used nuclear fission power.

At its core, its peak energy output would reach 100 million degrees Celsius, four to five times hotter than the sun.

Even the power of Rank 7 Divine Beings would be inferior to such explosive power.

But despite such great explosive power, the nuclear weapons weren't practical in killing Rank 6 Divine Beings, let alone ones that were Rank 7. Its destructive power was too widespread and instantaneous.

Nevertheless, it was still more than enough to give Abaddon the scare of his life.

When Vaan's hydrogen bomb detonated right before the Asura Domain, it lit up like a newborn star, radiating blindingly throughout the space region.
