I’m in the Tang Dynasty, and You’re Giving Me a Cultivation System?

After transmigrating to the Tang Dynasty, Li Chengqian becomes Li Shimin's legitimate eldest son, the Prince of Qin.

Li Chengqian isn't fazed when he learns he's transmigrated, because a cultivation idle System bound itself to him the moment he was born.

The only odd thing is the System's activation condition: he has to wash Li Shimin's face.

With no other choice, the newborn Li Chengqian activates the System by peeing all over Li Shimin.

And so begins his path to immortality.

By the fourth day of the sixth month in the ninth year of Wude, Li Chengqian has reached the peak of the Golden Core stage when he receives his first System mission.

“Ding! Host, proceed to Xuanwu Gate and change how events there unfold.”

“Rewards: one Peak Mahayana Trial Card, usable for two hours; one Substitute Puppet; and one Nine Heavens Resurrection Talisman.”

For the sake of the rewards, Li Chengqian has no choice but to stop hiding his abilities. He uses all sorts of spells to strengthen the Tang Dynasty and transform it into a supreme immortal dynasty.
