It was Xiao Yan who helped the inner court solve the problem of exhaustion of carditis caused by the fall of the natural gas tower. When he returned to the ground where he found his fallen heart, Xiao Yan was chased by underground monsters, and finally fled to the space blocked by Mr. Yao with the power of fighting, and was saved by Mr. Yao. Mr. Yao was seriously injured when recovering from collapsed carditis, but his soul did not die. It was not until Xiao Yan arrived that he was finally brought out of the ground by ZSZSZSZ, but because he had been there for many years.
Mr Yao appeared in chapter 878! ! You can go and have a look.
