The Junior from My Sect is Too Talented

Wang Shuo is the only disciple of Spirit Cloud Sect's Formation Peak Master, until his old master brings back a little junior sister from his journeys. Unfortunately for Wang Shuo, his old master has no idea how to care for children, causing him to raise her on his own. Will he be able to keep the dignity of an elder brother and raise her properly while not falling back on his cultivation? Or will it be that he is surpassed by even those younger than him? His new (obsessive) junior sister seems to agree that the second path is more fitting for him.
