Versatile Mage: Lord of Wind and Rain

When he woke up, Wang Yu, a civil engineering worker in his previous life, traveled to the magical world of a full-time mage and became a poor young man in an orphanage in Bo City. Fortunately, as a time traveler, he possesses the two natural attributes that every time traveler across the world must have. Originally a foreigner, he just wanted to use magic to improve his life. Wang Yu never expected that his magic talent was so powerful. No more pretending, I'm showing my cards, I'm going to change this fucking world! Later historians wrote in their papers: A small step taken by Wang Yu is a giant step for all mankind. In fact, Wang Yu just used his imagination and took risks in this wonderful world. As for why the temple, the holy city, the sea monster, and the ice emperor are so well-behaved, that is really fictional history!
