A Mysterious Creature

Having soldiered on for a long time and reaching the end of the Tomb, the soldiers and cultivators were all tired. And yet, when they saw the final door, they all felt a newfound wave of motivation flowing through them.

"Let's open it!" The cultivators said, 

"Wait! We have to check it first!" The commander spoke before turning to a specific group in the back. "Formation masters." He called.

Four cultivators walked out of the group and checked the door with their different methods. Some used spirit tools, and some used their own skills. Regardless, they all had a frown on their face by the time they were done.

The commander and the rest saw this and knew something might be wrong.

"What's the issue?" The commander asked. 

"Yeah, is there some trap there?" The others asked as well.

"No… rather there is nothing here… no trap or even a normal formation." One of the formation masters spoke.
