With the two women in tow, Li Su moved swiftly, directly breaking the sound barrier.
By his calculations, they had already been out for two shichen. The battle at the ancient city had taken a little over nine shichen from start to finish.
In other words, they had spent more than eleven shichen in the Immortal Prison.
Less than one shichen remained before the day ended.

That was why Li Su had to hurry back. Even the natives would suffer the punishment so long as they remained outside the ancient city.
But if they suddenly woke up and all returned to the ancient city just as the punishment descended, the situation would undoubtedly become extremely troublesome.
The Immortal Prison's punishment was severe.
Why had the natives been so confident that these outsiders would inevitably slaughter one another? It had a great deal to do with that punishment.
