The Black City where the Black Tortoise of the North is residing could be seen safe as the people of Kami could not enter it as freely as they thought. The mysterious city where everything is shrouded in mist and fog became a death trap for those that wanted to kill the Black Tortoise of the North. The entrance to this very city is guarded by the Black Tortoise of the North which means exiting it also needs its authority.
The forces of Kami managed to infiltrate the city, but they could not exit it. As soon as they forcefully used a hidden entrance, they were met with a dense fog instead of a city. In this dense fog, the soldiers of Black City were all invisible to the forces of Kami. The forces of Kami died without even having known the faces of their killer.
