Inside the Heavenly Principle Tower.
"I've already breached the sixty-ninth floor, yet I still can't get out..." Lin Yun had just fought a bloody battle with a group of powerful combatants and his body was drenched in blood. He looked up at the murky sky above and sighed softly.
The passage of time within the Heavenly Principle Tower was not easy to calculate accurately, but he could roughly figure out that a year and a half should have passed outside the tower if he hadn't miscalculated.
A year and a half had gone by without leaving the tower; what could have happened in the outside world during that time?
He had a premonition that if he didn't leave when he should have, the events unfolding outside could potentially develop in an unfavorable direction.
