[Crossover] Call Me the First Qin Emperor

Years later, after returning to the martial world, master and disciple sit together under the moon, drinking. Yang Duyou says, "My experiences are unlike those of my junior brothers and sisters." Yang Qingyue asks, "How so?" Yang Duyou replies, "I've seen Dongmu beneath a sky filled with flames, walked through a future where humanity itself was incinerated, survived the brutal Beast Front, witnessed the ninja wars of the Warring States period, and visited Heian-kyo, where humans and ghosts lived side by side." Yang Qingyue, thinking to himself: What places are these? Yang Duyou continues, "Oh, and I brought your future son-in-law back, too. Would you like to meet him?" Yang Qingyue: "!!!" *Special bulletin! Senior Sister Duyou's love interest has arrived at Changge Sect! The big shots of Changge Sect ponder for a long while. Han Feichi: Come here. Listen to my Illusory Demon Melody. Feng Xiyan: Come here. Listen to my One Heart, Two Minds. Yang Yifei: Come here. Take my Immortal-Breaking Sword strike. Love interest: QAQ Please spare me. Yang Qingyue, Changge's Strongest Voice, Master Tiger: Come, my dear disciple's love interest. Master Tiger will play you a song~ Han Feichi, Feng Xiyan, and Yang Yifei: Let's go, let's go. Looks like there's no need for us to step in. Love interest, deceased. [Reading Guide] 1. This is a self-indulgent story, a self-indulgent story, a self-indulgent story, a self-indulgent story (with echo). 2. The author's imagination has split the heavens. Please don't nitpick the details. 3. The female lead is an NPC from the Changge Sect in Jian Wang 3, and she's just as overpowered as ever [shrugs]. 4. The pairing hasn't been decided. Anyway, he's a handsome guy... probably?
