Gu Zhen Ren
Tao Zhu's looking to be a good subordinate for Fang Yuan, dude has perseverance second only to Fang Yuan himself. And with his inheritance, Fang Yuan's battle abilities should become more variant and fluid as rule path seems to be a good supporting path to have.
On the downside, this Ba dued wont be one of the 4 rank 8 southern border invaders..fy needs to also consider northern and southern plains regarding their war against heavenly court. Hopefully western can contribute more.. given fang clan is being ****ed over by fy that seems hard. As for eastern, fy can potentially gain 4, no, 5 rank 8 powers in the 4 enslaved rank 8, the gu house itself and di zhang sheng, but duke long is a massive issue... He really needs to consider the power of the 4 regions when plundering since without enough support he is ****ed against HC unless some even more drastic advantage is gained to shadow sect/variant human forces.
With this I think FY is now at least Grandmaster in all 5 Demon Venerables paths. Rule Path Great Grandmaster for Limitless, Transformation and Strength Grandmaster for Reckless Savage, Time Quasi-Supreme Grandmaster for Red Lotus, Theft Great Grandmaster for Thieving Heaven, and Soul Grandmaster for Spectral Soul (I think I read he raised it with a Dream Realm, can anyone confirm?). Hopefully he has time for Crazy Demon Cave now.
