Big Ivan?
This was the name of the famous super hydrogen bomb in the former Soviet Union during the Cold War.
Huo Shaoheng had once explained to her that Big Ivan was the largest, heaviest, and most powerful bomb in the history of mankind.
Its maximum explosive yield was equivalent to 100 million tons of TNT. However, the Soviet government was worried that it would have a serious impact on the environment, so it halved its power, it changed the explosive yield to 50 million tons of TNT.
Even though it was halved, Big Ivan was still awe-inspiring.
Compared to the two atomic bombs that the United States dropped on Japan at the end of World War II, "Little boy"and "Fatty", Big Ivan's explosive yield was 3,800 times that of "Little Boy", it was 2,300 times that of "Fatty".
