"Gongsun Wen Tian is so ruthless!"
Those who were not from the Gongsun family gasped when they heard Gongsun Wen Tian's words. They felt Gongsun Wen Tian was too ruthless for forcing Duan Ling Tian to choose between swearing on the lightning penalty oath according to his request and death. He was even willing to sacrifice himself to achieve his goal.
Gongsun Wen Tian was not certain if Duan Ling Tian's technique was a Celestial Method or a Celestial Supreme Treasure.
