Swallowing energy, the [level] skyrocketed! Bite! Devouring success! Obtain the skill [Corrosive Saliva]! [Ding! Blood purification! Unlocking the racial evolution route - [Iron-beaked Sparrow] → [Hundred Poison Hunting Sparrow] →... → [Destroying Poison Phoenix]? [Ding! Eat [Ancient Thunder Core] and get the talent [Thunder Devourer]! The useless bird that was once ridiculed began to evolve towards the indescribable God of Devouring under his feeding!
