Global Strike, I Am Refining Missiles in Another World!

Lin Feng, a missile expert from the Dragon Kingdom, woke up and became a slave from another world? Exhausted of spiritual energy? Is the flying sword as slow as a snail? Watching the gods and demons flying in the sky, Lin Feng silently took out a wrench and slide rule. "To cultivate immortality, you must also pay attention to science!" Hand-made explosives are just the beginning, including rocket launchers, surface-to-surface missiles, electromagnetic guns, space-based weapons... And even the ultimate truth - an alien version of nuclear bombs! When the floating city of the Kingdom of Holy Light covered the sky and the sun, millions of monsters in the Abyss Demon Realm roared and charged. Lin Feng just pressed the launch button: "Dongfeng Express, free shipping worldwide, mission will be achieved! Please sign for your - truth!" This is the story of a hard-core military engineer who crazily climbed the technological tree in the world of immortality and used absolute firepower to prove the "truth"!
