Fang Daozi is the first born son of the First Generation Fang Clan Patriarch. He was one of the Fang Clan's best and brightest, until he betrayed his clan to join the Ji Clan during the war for the position of the Lord of the Ninth Mountain and Sea. This wasn't because he was a traitor, but because Lord Ji planted a karmic seed inside him. This required a significant amount of Lord Ji's cultivation to succeed and to escape the detection of the First Generation Fang Clan Patriarch. Fang Daozi's betrayal incited chaos amongst the ranks of the Fang Clan and allowed the Ji Clan to win the war for the lordship of the Ninth Mountain and Sea.
Still, the First Generation Fang Clan Patriarch couldn't bear to execute his own son, so he punished him by making his soul forget his current memories and be reborn each time in a new body. Eventually, he regained his former self and started plotting the overthrow of the Fang Clan.
Eventually, with the help of Fang Xiushan, Fang Heshan, and the Ji Clan, he managed to incite about 50% of the elders of the clan into rebelling. Hundreds of thousands of lives were lost and it seemed the rebellion would succeed. However, the First Generation Fang Clan Patriarch's clone had cultivated the One Thought Stellar Transformation to completion. This allowed him to become planet East Victory and undo all the deaths that took place. He could even choose to kill the traitors and save the innocent, which he did. Afterwards, Fang Daozi learnt the truth about himself and left.
