This is not a serious novel, it is full of nonsense.
The protagonist lives every second? Doesn't exist.
Time travel, multi-universe link, with a bit of fantasy.
I am an unknown prince and grandson, who was involved in the internal strife within the royal family due to the Maweiyi Incident.
To quell the Anshi Rebellion and ignore Tang Suzong and Li Heng, it doesn't matter who the emperor is.
I am the real emperor of the Tang Dynasty, and I am the thigh that the powerful people of the Tang Dynasty hug tightly.
It's also good in some Anshiwen
