(It’s not like Kent is a lazy guy who escapes studies. Most of Kent’s meridians were locked down by a curse.)Suddenly on the same day, Kent received a Raven from his maternal aunt. “Are you really my aunt?” Kent questioned with a doubtful gaze. “Yes, Kent… I have sent 5000 gold and Heavenly elixir to remove your meridian curse. Don’t mind asking me for more money. Your mom left a huge fortune for you.”From that moment Kent’s life changed as he brought a new flying pet equal to core disciples, new weapons, Villas, Fancy meals, and whatnot. Soon, his powers sore and he became a Supreme Arch Magus.
