Cultivation knows no years, at least for Ye Feng and his companions currently in the Tower of Time, this was indeed the feeling they lacked.
One man, five beasts, and a divine medicine plant, all deeply immersed in cultivation, felt their cultivation levels growing incessantly.
Moreover, with the energy support from strong individuals like Xu Yan, Xu Shi, Xu Mi, and Xu Qing, the boundary breakthrough journey for Ye Feng and his beasts became much simpler.
Given Xu Yan's height, the profound mysteries of the Dao contained in his power were like a massive tonic for someone like Ye Feng, who was several realms below him.
Especially since Ye Feng himself possessed five Imperial Beasts with extremely strong talent potential, his own aptitude and potential were also incredibly robust. What he lacked was merely time for cultivation.
Now, in such a rare cultivation environment, he soared even more rapidly.
Ten years, twenty years, fifty years, ninety-nine years!
