Inside the XY Building.
There were no obstructions on the staircase leading to the second floor.
Only, at the junction where the staircase met the second floor, there was a thick, pure black stone door.
In the middle of the stone door, there was a concave slot about the size of an infant's fist, with rows of dense characters etched beside it.
The general meaning was that pushing open this stone door required at least the strength of the Immortal Emperor Stage. If the person entering was not at the Immortal Emperor Stage, they could drip fresh blood into the concave slot.
If their talent was strong enough, they could temporarily take control of the XY Building, and wait until they had the strength of the Immortal Emperor Stage to try pushing the stone door open again.
It seemed that the stone door had the ability to test talent, and Shen Feng was completely confident in his current talent. He was certain he could eventually return to the Immortal Emperor Stage.
