Rubbing nuclear bombs with your hands, you say you are the weakest technology department?

[System + National Job Transfer + Game Fusion Reality + Invincibility + Funny Sand Sculptures] 　A red moon opened the era of job transfer for all.Instances, cracks, and secret realms are everywhere, challenges, risks, and opportunities coexist.Everyone is fighting monsters and upgrading to become stronger in order to deal with unknown threats in the future.And Zhou Han changed his job at the fifteenth level to become a technology pioneer.One of the weakest science and technology departments in the world.Slow skill release, low power, long cooldown, everyone hates it.Just as Zhou Han was lying flat, the scientific system suddenly appeared. "Ding! The ability to assemble nuclear bombs has evolved to the destruction level, and you can assemble nuclear bombs at supersonic speed with bare hands!""Ding! The black hole collider skill has evolved to the destruction level, and the portable dimension destroys the black hole!""Ding! The electromagnetic turret skill has evolved to a destructive level, a cluster-type billion-volt electromagnetic railgun!" 　From then on, Zhou Han started a very scientific path of skill evolution. 　Horizontal pushing dungeon, leapfrogging treasures, competitive crushing, national war to the top!Until one day, all races invaded.Standing on the shuttle-type Eclipse-class Star Destroyer, Zhou Han looked down at them, and said with a smile, "Have you eaten yet? If you haven't eaten, give me a shot first!"[The introduction is weak, please move to the text]
