Two days ago, The Shang Clan's prison tower,
Han Wuji was looking into the distance with a lost expression, his gaze devoid of hope. His clothes were torn, revealing his wounded skin. His body lay without any life on the ground.
At this moment, a guard came and knocked on his cell door: "Prisoner Han Wuji, Young Lord Ashen is here to see you. Get ready and come out."
He was then brought to the guest room where Ashen waited while sitting on the couch.
This prison tower had a formation around it that sucked all the qi from inside, making this tower devoid of any qi.
Any prisoner inside couldn't use qi to use their arts and as for the qi in their core, it only lasted a few days inside the formation before being depleted.
This rendered even the emperor realm prisoners helpless. The only way to escape from this prison tower was on the first day when your core could support the use of high-level skills.
