Thousand-Face Mask

Today, the night sky was filled with dark clouds while icy winds were blowing and the clouds were rumbling occasionally. 

Everyone knew it was going to be a stormy, rainy night, but the Ocean Demon City was bustling with activities as those cultivator demons didn't feel the cold of winter. 

Ace was currently walking on the ocean demon city's streets in stealth, and no one could see him at all as he passed them. He looked like someone on a stroll. 

'This city is more than twice the size of Iron Demon City, and there's a strong defensive formation surrounding it. Livy used it last time to entrap us. I also have one of their legacy formation in my hand, but my run crafter rank is too low to repair it.' Ace thought as he scrutinized the city.
