Some say that Marquis Zhenguo is the bloodline of the former emperor, the flesh and blood that the former emperor once lost among the common folk. And before the former emperor passed away, he had already included Marquis Zhenguo on the Imperial Decree, only missing the final announcement to the public when he unexpectedly ascended to immortality.
Some say that even the death of the former emperor was deliberately caused by someone, with the purpose of preventing Marquis Zhenguo from recognizing his ancestors and returning to the clan!
Some say that the reason why the current emperor has dispatched various Great Armies to deal with Marquis Zhenguo is to silence him by killing him, in order to firmly secure his own throne.
