Global Doomsday: I Build a Mecha to Save the World

On the peaceful land of Blue Star Dragon Kingdom, a giant bloodthirsty spider 100 meters tall suddenly appeared, devouring humans and destroying the city... The Dragon Kingdom assembled millions of elite soldiers and heavy artillery to fight against the monster. Unexpectedly, the monster had an unknown shield to defend itself, and any attack was of no avail. When the Dragon Kingdom was helpless and its citizens were fleeing, a dark blue laser came from the sky and penetrated the monster's shield like a thorn. The next second, the mecha fell from the sky and removed the monster's head with one punch. At the end of the battle, light and shadow broke through the sky, the huge steel instantly disappeared, and a high-spirited young man appeared in everyone's sight. Interview: "Comrade Lu Yan, did you build the mecha?" Lu Yan: "I made it, a man-made one." Interview: "What is the purpose of building mechas? Is it just to fight monsters?" Lu Yan smiled sweetly: "What else can I do? Save the world!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
