In the first year, he signs in the Web of Darkness, whose agents are everywhere and whose intelligence is always accurate.

In the second year, he signs in the Sword Sect and takes control of the martial world.

In the third year, he signs in the Mirage Ship. It sails the oceans, bringing Western crops and seeds back to the Central Plains in an endless stream.

It is the ninth year of Wude. Tensions between Li Er and Crown Prince Li Jiancheng escalate.

The poisoned wine sent by Crown Prince Li Jiancheng fails to kill Li Er. Li Er begins plotting the Xuanwu Gate Coup, preparing to kill Li Jiancheng and Li Yuanji and force Gaozu to abdicate.
