There are many such novels ~ I recommend a few! "Divine College: Seraph Rebirth,""The Universe Master's Growth Plan,""Starlord: The Path of Pledge,""The Long Way of Naruto,""Skill Becoming a Saint,""Carefree Movies,""Almost Invincible,""The Legend of Marquis Wen at the End of the Han Dynasty,""The Proud Spark,""I'm a Big Boss in Fantasy" are all good choices. These novels don't have stallions. The main characters are mature and definitely won't disappoint you. I hope you like this fairy's recommendation. Muah ~😗
