After obtaining the Spherical Heaven Chessboard, Shen Tian immediately felt that this wasn't a loss.
But then, he thought of a serious problem.
After being in seclusion there for 180 years, the Supreme Sky Tree World had long closed.
The Supreme Sky Tree World would only open for 100 years. By then, the cultivators inside would be automatically pushed out.
Then, the entire Supreme Sky Tree World would disappear into the void and would only appear after another 8,000 years.
As a result, no one had ever remained stuck in the Supreme Sky Tree World.
However, Shen Tian was currently inside the Spherical Heaven Chessboard.
This was a separate dimension from the Supreme Sky Tree World.
The problem was that the Supreme Sky Tree World was closed. How could he get out?
Shen Tian inquired, "Senior Immortal King, how should I leave?"
