In the big black space
There were five boxes floating. After the five boxes appeared, Tony started his explanation "The fourth floor is very complex, filled with never-ending space, of course, above the fourth floor, the condition is same."
"This space had both function only has Dao Comprehending and Time manipulation. But unlike the first three floors, here your real lifespan will be consumed for the greater time difference. Previous one day was equal to five days, one month equal to five months and same goes for a year but now, one day is equal to one month."
"But unlike the previous time, this time you need to spend Immortal crystals to use this space. One Immortal Crystal is equal to one day inside. More importantly, here you can use the dao of comprehension and the power of time at the same time."
