Tang Yin had arrived very close to Treasure Bank City, he would have arrived much earlier if he did not spend time hunting down High-tier Rank 2 Demonic Beasts for Xiao Fei.
But this was worth it, he was not in a hurry. Not only was Xiao Fei evolving to become a stronger aid and companion, but Tang Yin had also accumulated a large amount of Qi within his Heaven Devouring Abyss. Although this amount was not enough to break into the 8th stage of the Physique Transformation Realm, it was close.
Tang Yin carried on heading south at a moderate speed, he killed and devoured any Demonic Beasts he met. This did not slow down his journey at all, it only increased the amount of Qi within his Martial Spirit.
A few days passed. Tang Yin was situated in a cave he had forcefully inhabited. The previous owner of the cave was a weak Rank 1 Demonic Beast, the cave was not that big.
