The temporal elasticity between the Heavenly Realm and reality was seven days. This meant that Yan Liqiang could only stay in the Heavenly Realm for seven days at most before he had to exit and return to reality, just like a save point in a game. If he prolonged his stay, the Heavenly Realm would 'collapse', as how Fu Guang described it.
This was the first time Yan Liqiang had stayed a full week in the Heavenly Realm ever since he had come to possess it. He'd always stay a day in each realm to preserve the balance of temporal distortion between the realms. The Heavenly Realm had always been exactly four years, four months, and eleven days ahead of reality. However, Yan Liqiang had unknowingly reached the upper limit — which was a week in the Heavenly Realm this time.
