Jian didn't know that when he had started refining the core, Wei Tengfei had disappeared. He didn't stop. He continued to refine, and after six hours, he was done refining it.
As he had completed the refining. He saw people inside the tomb. He was able to see every layer of the grave. He opened his eyes and saw that no one was there except him, so he understood that Wei Tengfei's soul had dissipated.
Jian then stood up and kept the score in the ring. He moved towards the remains of Wei Tengfei and started to dig a grave. He has decided that he will bury Wei Tengfei before leaving the tomb.
Jian didn't use his Qi while digging the grave. In refining the core, all his Qi was gone, but still, he had decided not to use his Qi to bury Wei Tengfei.
Jian took half hour to dig the grave and bury Wei Tengfei's remains. After planting, he bowed and sat down to recover his Qi.
