App Profile: Mountain digger

A long time ago, there was an old man named Yugong. Two big mountains at the door of his house blocked the cell phone signal, which greatly affected his life. So he decided to work hard to have more children to remove the mountain, but was ridiculed by the wise old man. Yu Gong didn't care and insisted on having children to continue moving the mountain. Yugong's persistent spirit moved God, and sent a little fairy to help him. . .
