Let You Earn Tuition During the Summer Vacation, and You Will Become an Arms Dealer.

Lin Yun traveled to a parallel world and worked as a summer job in a toy factory in order to earn tuition! As a result, the toy dogs produced could not be sold, the capital chain was broken, and the factory was on the verge of bankruptcy. Seeing that the tuition money he earned was going to waste, Lin Yun, who had awakened the most powerful weapons system, stood up resolutely. "Since toy dogs can't be sold, let's change our thinking!" "First use iron sheets to reinforce the whole thing, and then use the latest infrared rays to add a rotatable compass on the back of the toy dog..." "As long as you purchase this product, you can get a modification manual as a gift!" "Hey! Don't talk nonsense, this is not a weapon! It's just a DIY toy that supports a high degree of freedom!" No one buys a toy dog that costs RMB 100, but after modification, it sells for RMB 10,000 and the supply exceeds demand! … Many years later, a mysterious boss in the military industry said that I really just wanted to earn tuition at the beginning!
