In a parallel world, this story explains many of the world's unsolved mysteries, including the origin of species, the Bermuda Triangle, the coffins of Barbados, and whether souls exist. How reliable those explanations are, however, remains to be investigated by Ji Han, the acting director of Shanhai Street!
Ji Han has lived on Shanhai Street since childhood, and occasionally takes a stroll around Shanhai Residential Complex. After the hiring requirements were raised, he had no choice but to pursue graduate studies under the formidable Yan. Together, they use the most "scientific" approach to unravel the world's unsolved mysteries.
What a wonderful pen, give a dive bomb as a reward!
