Li Yuanqing did not leave after dealing with the Patriarch and Goddess of the Wings Clan.
He had obtained the Demon Sealing Sword Formation and could seal this catacomb.
A place like the catacombs could not be opened at all. It should be completely sealed and checked from time to time.
Therefore, Li Yuanqing spent the rest of the time setting up the Demon Sealing Sword Formation in the catacombs. From time to time, he would even think about how to strengthen it.
Ordinary people did not dare to enter because this cave was the holy land of the Wings Clan. Therefore, Li Yuanqing stayed inside for a few days until he had set up the sword formation and completely sealed the catacombs before leaving the cave.
Li Yuanqing remembered that the Patriarch of the Wings Clan and the Goddess had once said that there would be three chances to loosen the catacombs. He should come over and guard these three times to prevent any future troubles.
