Li Er of the Tang Dynasty: Ancestor Xie Is Here!

(The copy of Ming Dynasty has been opened, starting with Chapter 154) In the sixth year of Yonghui, Li Shimin, who was taken through time by Li Qing, stood in front of the Zhengzheng Hall, looking with affectionate eyes full of anticipation for the ceremony of canonizing his youngest son as queen. The moment he stepped into the Li Zheng Hall, Li Er completely broke his defense. "Child slave! Why are you with Mei Niang?!" Li Qing, who obtained the system, received a systematic task. As long as he can take the twenty parallel planes of the Tang Dynasty to complete the achievement of "there is only one Tang Dynasty in the world", he can become an immortal instantly. Li Qing said that becoming an immortal is secondary, and I want to have fun first. This is a story about leading Li Shimin to violently beat up the ignorant kings of later generations.
