Seven days later.
Inside a temporary cave abode amid the remote mountains of Seven Star Commandery.
Within the space enveloped by the Grand Formation's light barrier, Gu Chenfeng sat cross-legged at the center of the cave abode.
At this moment, silver threads wreathed Gu Chenfeng's body, forming dense, heavy Profound Baleful Armor.
Now the silver threads spread again, resembling countless mysterious runes as they covered the entire suit of armor.
The energy armor, which had radiated dense Yin Baleful Qi and been as thick as heavy plate, now began to contract rapidly, like droplets seeping into the earth.
