In the Tang Dynasty, I Made Hundreds of Officials Crazy by Practicing Evil Writing

Xiaren traveled through the Tang Dynasty and became the second son of Cao Guogong Li Ji. Before he could figure out his new identity, Li Shimin's imperial edict came. All the descendants of civil and military officials must go to the Ministry of Civil Affairs and accept the assessment of Changsun Wuji, and those who pass will be directly promoted to officials. But Li Ji had offended Changsun Wuji in his early years. Seeing the obviously malicious sneer that Changsun Wuji looked at him, Xiaren knew that there was no room for change in this assessment. In order to gain a foothold in the Tang Dynasty, he had no choice but to abandon the righteous path and embark on the path of evil cultivation.
