The entire ancient tower, made of unknown yellow stone bricks, is covered in numerous mysterious ancient runes. Although these runes appear random, they seem to form part of some array patterns.
The ancient tower has only one large entrance. From the outside, apart from the entrance and the runes, the stone tower appears exceptionally smooth and straight.
Standing before the door, Feng Yuan looked at the tightly closed entrance and said,
"Not sure if there are any defensive measures here. You all should protect yourselves."
As he said this, Feng Yuan swung his long-handled sickle forcefully. A black-robed phantom gathered behind him, pushed its hands towards the door. Instantly, array patterns and formations appeared on the door, but they were entirely unable to stop the black-robed phantom summoned by Feng Yuan.
Behind the slowly opening door, no blinding light emerged. Yet, to everyone's eyes, that bizarre space might not be particularly safe.
