Transmigrate as Li Chengqian, and It Turns Out to Be Journey to the West?

Synopsis (serious version):

After transmigrating, he becomes Li Chengqian, the crown prince of the Tang Dynasty, whose rebellion has just failed. Li Er is holding him accountable when a dragon’s head suddenly descends upon Chang’an!

Isn’t this the Jing River Dragon King who gets executed at the start of Journey to the West?

What? I’ve also been bound to a Recognition System? If I can earn the approval of characters from Journey to the West, I can draw their cultivation, spiritual treasures, and divine abilities?

I have to find a way to hitch a ride on this Journey to the West!

Li Er, you wouldn’t want to earn a reputation as a father who killed his own son, would you? I’m willing to go west to fetch the scriptures and leave the center of political power for good!

Tathagata, you wouldn’t want the scriptures to gather dust in the Tang Dynasty, would you? With the Tang crown prince personally joining the scripture-fetching project, you can rest assured.

Synopsis (silly version):

Tang Sanzang covers his face. “Your Highness, why did you hit me again? Huh? You say chanting the tightening spell to abuse animals would make the Tang Dynasty lose face? Your Highness does have a point. I didn’t think it through.” (System notification: M-as-in-masochist Tang Sanzang’s approval +3)

Sun Wukong hisses. “Your Highness, these are the ginseng fruits I stole. Hurry, eat up. We’re good pals, so of course I’d share the good stuff with you.” (System notification: Sun Wukong’s approval +5)

Zhu Bajie chokes up. “Your Highness, this old pig finally got to enjoy the good life too. The girls at the Yihong Courtyard are so lovely! Let’s hurry back before the old monk finds out we were out all night.” (System notification: Zhu Bajie’s approval +10!)

Sha Wujing is ecstatic. “What? The leaders will see all my hard work and won’t let me down? Loyalty!!!” (Notification: Sha Wujing’s approval +20!)
