Lingxiao

When he and the other Sacred beasts were mortally injured he was entrapped by a group of people and could not leave or they would be notified and he along with Yunyao, Tianqiong, and Chi would be put into even more danger.

Not long after being trapped by the runes the Xia Family Ancestor found him and under the orders of finding his friends he used his Martial Honor cultivation to helping the Xia Family grow to their status today.

When Old Master Xia finally found Yunyao and Tianqiong he was almost at the end of lifespan because the runes turned him into a normal Martial Honor (Divine Beast lifespan is much longer) so Gu Ruoyun gave him a Longevity Pill to survive until Zixie was strong enough to break it.

Tian Gu came to the Xia Family at the request of Gu Ruoyun to expose Xia Qi, after doing so she used Tian Gu's strength to replace Xia Qi inside the matrix so he could be freed of the punishments that the matrix creator (Lin Yun would randomly give him.

When Gu Ruoyun returned to the Xia Family he was on the brink of death because Lin Yun found out about Xia Qi so Gu Ruoyun tried to free him from the formation but Lin Yun tried to stop them only to have Qianbei Ye redirect the attack back on him.
