The System Forces Me to Bring Disaster to the Tang Dynasty and Create a World Where the Sun Never Sets

Time travel to Li Shimin, who has just experienced the Xuanwu Gate Incident, and faces the first task of the system: to kill Li Jing (or another important minister) to establish his power. In extreme pain and fear, the protagonist relies on modern conscience and understanding of history to resist the electric shock punishment, and chooses to forgive and even subdue Li Jing. A strange phenomenon (thunder) from the sky causes the system to temporarily shut down or bugs appear, making the protagonist realize that the system is not absolutely irresistible.
