When Lucius and the others heard that, they just nodded their heads slightly and said.
"We can't afford to stop since if we do that, then we will be caught by the demon" Lucius exclaimed, his voice carrying seriousness.
They took a closer look at the demonic aura and realized that it was much stronger than before. It was growing stronger with each second.
"Move as quickly as possible" Lucius gave out commands to his summons as they started to walk forward.
They kept walking forward which caused the demonic aura to stop growing stronger. As they walked forward, they occasionally heard the howl of some beast from the distance. They ignored it and kept walking forward.
After what felt like an externality to them, they spotted an exit from the distance which probably led them to a much open area.
They hastened towards the exit, and upon stepping outside, beheld the tunnel's termination.
