Tao Zhiyue tried to teach the straight male netizen some coquettish manipulations of rejecting other people’s love, and the effect was remarkable, and he successfully strangled the other party’s peach blossoms!

Later, the netizen, who he had an increasingly ambiguous relationship with, invited him to formally meet him, and he went to the appointment with a throbbing heart.

The tall and handsome man stretched out his hand nervously, blushing: Hello, my name is Huo Ran.

His familiar school had become a mystical school that teaches magic, encouraging everyone to become a mighty magician.

Outside the city, many wandering magical beasts and monsters attacked and preyed on humans.

However, Mo Fan found that when most people could only practice a single major element of magic, he was a Versatile Mage!
