Inside the great hall of Qiankun City, the illusory river above Chen Fei's head appeared for a moment before slowly fading away.
Chen Fei had fully condensed the Time Subordinate Rule [Past]. With that, he had finished cultivating all three known time subordinate rules, condensing them into an incomplete Time Rule Crystal within his soul.
