Zhang San initially just smiled when he heard what Lady Yu said, but soon, he could not smile anymore.
What Lady Yu had just mentioned was not "Kaihuang" but "Yang Jian"!
This was actually the taboo name of Kaihuang; who would dare to call him that directly?
Yet his sister had just called him that directly.
Could she be Yang Jian's concubine?
Zhang San had heard that Kaihuang and Empress Gudu were deeply in love.
When they had their grand wedding, Kaihuang had pledged his fidelity to only the Gudu Clan for this lifetime.
Was his sister really that audacious?
That couldn't be right!
If that were true, how could Empress Gudu possibly refrain from taking action while allowing the Yu Family's business in the Capital to grow so large?
For a moment, Zhang San was unsure of what relation his sister actually had with Kaihuang.
"By the way, brother, I recently met a Taoist who predicted that I would face a disaster of fire soon. Do you know any way to ward it off?"
