Xuan Qing Island wasn't as simple as he had imagined.
The Three Heavenly Cities were also wary of Xuan Qing Island because of its secrets.
Furthermore, the three Heavenly Cities had been eyeing Xuan Qing Island at all times. They were only afraid of Xuan Qing Island's Array Dao, which was why they had not come to cause trouble. If Xuan Qing Island did not have a powerful Array Dao, the three Heavenly Cities would have started a war long ago.
While they were wary of Xuan Qing Island, the three Heavenly Cities had never given up on Xuan Qing Island. This was because Xuan Qing Island had a shocking secret. If they could enter Xuan Qing Island and obtain this secret, they would be rich.
It was precisely because of this that the three major heavenly cities and some supreme experts were eyeing the island covetously.
However, no one dared to attack Xuan Qing Island forcefully. If they did, Xuan Qing Island would be reduced to dust.
