The Whole World Knows That I Will Be the Emperor

This article is expected to be published in v on October 7th, and will be updated in v three times. Please support me, little angels! Copywriting: "Emperor Renzong Xiaozhao, taboo Yuanxun, Taizong's eldest son. His mother, Queen Renxiaowen..." - "Book of Zhou·The Chronicles of Renzong" Qi Yuanxun, the male protagonist of Renzong's Ancestor and an emperor by profession, should be a well-deserved winner in life - after all, history books are the last word! As an emperor with a beautiful posthumous title, Qi Yuanxun should die without regrets. But the problem is that the current Qi Yuanxun is a fourteen-year-old boy. The person sitting on the throne now is not his descendants, nor the emperor of the new dynasty who ordered literati to compile the history books of the previous dynasty, but the founding emperor of the Great Zhou Dynasty and his imperial grandfather Emperor Xuanwu. Qi Yuanxun, whose face was spoiled by the light curtain that suddenly appeared in the sky and could be seen by the whole world, was not happy at all. In the twenty-fifth year of Xuanwu's reign, the prince's uncle passed away. After a series of squabbles among the elder princes who had vassaled the princes, the prince's eldest son reaped the benefits and was appointed as the emperor's grandson. Question: His father is a vassal king, and he is the son of a vassal prince. Under what circumstances can he become the emperor one after another after the heir has been determined? Qi Yuanxun, who was obviously just entering the palace and attending the palace banquet in the 26th year of Xuanwu: It's so difficult for me! Ps: The male protagonist will marry a wife, but there will be no emotional scenes, so no cp is decided. Intention: Practice is the only criterion for testing truth
