Jiang Qiao's Fureya was not injured; the real reason the Holy Spirit team forfeited was that Thorne disappeared.
Although the Four Knights were nominally Thorne's teammates, in actuality, Jiang Qiao also intended for the Four Knights to monitor Thorne's every move on the Path to Ascension.
However, Jiang Qiao ultimately underestimated Thorne's ability to escape; the Hornet Knight had been tracking him across Biland Island, but an hour later, Jiang Qiao learned from the Hornet Knight that they had "lost track of Thorne."
This female knight wanted to apologize to Jiang Qiao, who casually punished her to go learn a random craft and then shifted his focus to where Thorne might have gone.
Combining the intelligence brought back by the Hornet Knight, it was deduced that Thorne had hidden inside the Ascension Tower.
What did he intend to do by hiding on the Path to Ascension? This thought emerged in Jiang Qiao's mind, and he checked the access he had to the Path to Ascension.
