Zhou Tian had a True God's Treasure of the Spatial System in his hand at the time. With the ability of that piece of clothing, if Zhou Tian needed to, he could return to his Divine City in an instant. As long as he didn't encounter an irresistible situation that would cause his Divine City to be annihilated instantly, Zhou Tian believed that if his Divine City faced a crisis, he should have no difficulty in providing rescue.
It was precisely because Zhou Tian had the ability for instant teleportation that, despite knowing that leaving his Divine City might invite attacks from enemies, he ultimately didn't take those external threats seriously.
Of course, even though Zhou Tian had the courage to leave his Divine City at that time, as he left the city, he unconsciously made some simple disguises. He didn't expect the enemies to recognize him immediately, but at the very least he didn't want his identity to be easily recognized.
