Si Lingxi underestimated the ability of the Mind Jade Seal in Lu Zheng's mind.
With the triple blessing of Phoenix Dual Cultivation, Flame World, and the transformation from the Jade Seal, Lu Zheng's cultivation advanced rapidly, shortening the cooldown period drastically and enhancing his strength impressively.
Si Lingxi thought Lu Zheng could only last ten days, but he actually endured for almost a month before reaching his limit. Moreover, the energy absorption speed surpassed Si Lingxi's expectations.
Until now, even dual cultivation and the Jade Seal could no longer help Lu Zheng increase his cultivation.
At this point, Lu Zheng's Dao Practice is nearing three thousand years.
Ten years of cultivation, three thousand Dao Practice, terrifying indeed!
Lu Zheng opened his eyes, divine light flashing within, and fire igniting in his pupils; his Phoenix Power was dense and pure, seemingly tangible.
