Fengshen: I Am a Fisherman, What Happened to Fishing Kunpeng?

Traveling to the prehistoric world, at the end of the Conferred Gods period, Zhou Yuan became an inconspicuous disciple of the Jie Sect. At this time, Jie Jiao's robbery was just around the corner. Many disciples on Jin'ao Island have chosen to run away. Fortunately, Zhou Yuan has awakened the fishing system. As long as he fishes on Jin'ao Island, he can get unexpected harvests. I caught a piece of scrap iron, which turned out to be the Dinghai Shenzhen, which helped me hear Zhongda Poyun Neutron. I caught a small fish and it turned out to be the reincarnation of the Dragon Emperor, who helped the Dragon Clan prosper and fought against the Saints with Jie Jiao. After catching a corpse, he unexpectedly obtained the law of swordsmanship and helped Tongtian perfect the Immortal Killing Sword Formation. Fishing out a Kunpeng Daozu... No, I, a fisherman, isn't it normal to catch a Kunpeng?
