For twenty years, to prepare for a possible war with another world, humanity's major powers had focused not only on homeland defense but, more importantly, on maintaining a deterrent against the gods of the other world.
Nuclear weapons were humanity's most powerful weapons—and its only weapons of deterrence.
Before nuclear weapons were born, there had been no weapon that could compare with them—not even atomic or hydrogen bombs.
In theory, the most powerful nuclear weapon, the hydrogen bomb, had no upper limit to its yield. As long as there were enough materials on hand, one could even build a hydrogen bomb capable of blowing up the entire Solar System!
A yield of one hundred and fifty million tons was by no means the largest yield humanity had ever produced.
However, to avoid attracting more eyes toward Earth, according to the treaty on nuclear weapons testing in other worlds jointly signed by the major nuclear powers, all nuclear tests in other worlds had to be reported to the United Nations. Their yields had to be below one million tons, and they could only be detonated underground.
The one-hundred-and-fifty-million-ton Super Hydrogen Bomb detonated this time might not have been the first nuclear weapon to appear in another world, but it was undoubtedly the first in this vast region.
Within the enormous mushroom cloud that connected heaven and earth, countless bolts of lightning danced like electric snakes, occasionally mingled with wisps of strange, dazzling radiance.
With the Primal Force involved, and because the atmosphere of the other world had a higher pressure than Earth's, the nuclear bomb's power here far surpassed its power on Earth.
It had become utterly terrifying.
Several minutes passed before the storm gradually subsided. Only then did the nearby gods cautiously dare to turn their attention this way. Their
