Granddaughter's Birthday Banquet Gift of a Mecha Drives the Scientific Community Crazy

Xu Fan, a student and welder, received an order to weld a 500cm tall mecha—the more futuristic, the better! It was a birthday gift from a beautiful female client to her scientist grandfather, and she assured him the money was plentiful. The difficulty was too much, and he was about to give up when he activated a super-powerful technology system, and the mecha was successfully built. On the day of the birthday banquet, the mecha made its debut, its cool and sharp design stunning everyone. The beautiful client was dumbfounded: "I think I added an extra zero to the height requirement!" Just when people thought it was just a model, the mecha's engine spewed out azure flames, and a powerful blast of air exploded throughout the venue, blowing the guests off their feet!
