Because...
The exalted Immortal Buddha would never care to know the name of a mere mortal.
Could it be...
that this unknown and mysterious existence Cheng Guang might possibly be an acquaintance of his own?
The Great Tang Emperor thought of this and fell into a spell of deep contemplation.
Cheng Guang did not realize that his casual remark had led the Great Tang Emperor Li Shimin to make so many connections.
The more connections made,
the less the Great Tang Emperor could guess his identity.
Cheng Guang was not overly concerned about this matter.
After briefly taking care of the Emperor's affairs, he returned to Duke Zhen's Mansion.
The task of subduing the Great Tang Emperor was now completely finished.
For Cheng Guang, the most important thing at the moment was to wait for the system prompt announcing the completion of the quest, and then to claim the system reward.
Cheng Guang left Chang'an City of the Great Tang.
