The pit formed by the eye sockets of Underworld Venerate's skull indeed seemed bottomless. Dao Zhun had been flying downward for three Chinese Hours and still hadn't reached the bottom. However, the destructive will in the atmosphere became increasingly intense. Even Dao Zhun felt extremely uneasy, as the aura of destruction was like invisible snakes roaming in the air, all trying to burrow into his body through his 36,000 pores. As a result, Dao Zhun had to constantly circulate his spatial attribute spiritual power to block the invasion of that destructive power.
When Dao Zhun had been flying downward for a quarter of a Chinese Hour, his surroundings had turned into complete darkness, with only the light from the entrance behind him shining like a luminous pearl. After three Chinese Hours, Dao Zhun didn't even know how far he had flown, only feeling that the oppressive power of destruction was becoming as substantial as if he were struggling through a quagmire.
