"Study things to gain knowledge, be honest and sincere" - this is the eight-character motto engraved on the gate of Tianqi Academy, and it is also the starting point for Chen Changan, a young farm boy, to change his destiny.
Coming from a poor family, he entered the academy to take the trial with his parents' expectations in mind, but he didn't know that he would make lifelong friends and enemies here. There is the gentle and gentle medical girl Su Mingyue, there is the heroic swordsman genius Lin Jingyu, there is the monk Yuantong who always likes to eat meat secretly, and the Taoist priest Qingfeng who is drunk all day long but hides it...
The days in the academy were as beautiful as a dream: they studied classics together, competed in martial arts, sneaked down the mountain to drink, and talked about their ideals under the moonlight. Until one day, a sudden change tore apart this tranquility. When trust turns into betrayal, when protection turns into sacrifice, when the phrase "I knew I would lose her in the end, I should have looked at her more" becomes an eternal regret, then Chen Changan understands that growth is always accompanied by pain.
