Shen Yi did not intentionally kill his opponents, but in his nature, even when catching a rabbit, a lion will exert its full strength cautiously.
The three individuals led by Du Weiguang, although they had saved their lives, would have been considered crippled if they had been in another power.
But after they were sent into the grand hall,
the group of Baiyu Capital Cultivators from the Ban Shan Sect did not appear too worried.
After all, practicing Spiritual Physique Technique involves close combat, making injuries more common compared to other Immortal Sects during sparring. If they didn't have any healing methods, probably 90% of the Sect's disciples would have been lost long ago.
Of course, aside from this,
the Body Refining prowess shown by Shen Yi was also a major reason why they were so calm.
As far as they knew, not to mention the Seven Sons, even the entire Southern Hong lacked any Sect specializing in Body Refining.
