The formation started shining and brought Long Chen to a different place altogether.
He appeared in a different place, and he noticed the guards surrounding the formation. As his shadow transformation was activated, he was not only invisible, but his aura was also non-existent.
He stood right behind the guards, but they couldn't feel him. The only way Long Chen was going to get caught was if he deactivated his Shadow Transformation or if he thought about killing the guards and his killing aura leaked. Since Long Chen didn't want to target the guards, he didn't have any killing intent towards them. As for his Shadow Transformation, he still had some usage left.
The formation was once again heavily surrounded. He understood that this was probably more guarded because this was the formation of the Twenty-Fourth floor. No one wanted anyone to go to that floor. Long Chen had noticed that the formations of the 23rd to 26th floor were the most guarded.
