Natsuya woke up, and He was no longer pinned against the wall. The front gate was open, meaning he could get out of this temple.
Natsuya: "It Worked! I'm finally free!! I survived death."
His hand and leg are fully healed, and he darts across the front gate. The seven swords awaken again from the well, forming a cone to impale him from the back while running, ending his life.
Natsuya: "I guess... this is the end for me."
Was it the end? He woke up again, resting on the same well, and his injuries had recovered without a scratch.
He went running to the door again, and the seven swords did the same, forming into a cone chasing after and killing him. Again, the same thing happened. He died, then recovered.
Natsuya: "*Running to the front gate again* I WON'T GIVE UP!"
Then, the swords ended his life again.
And again.
And again.
And again.
And again.
And again.
Natsuya: "*Sprinting in high speed, as fast as a cheetah, close to the front gate* ALMOST THERE.... DON'T KILL ME NOW!!!!!"
Then...
The swords killed him again.
At one point, Natsuya kept running to the gate, the swords killing him before reaching the exit. He tried doing it one last time after 99 times. The swords killed him again, and after that, the swords pinned him to the wall, just like after lighting the torches, meaning that he couldn't move or escape. At this point, he lost consciousness.
Hours later, a group of administrators from the corporation dug up the large pile of rocks that Sang-guk made to abandon the team ran to where the temple should be, still it disappeared without a trace, just a large, hollow cave that used to be Natsuya's nightmare, leaving his body on the ground, with the swords disappeared, and his hand and leg was fully regenerated, like nothing happened.
Administrator #1: "A non-hunter... why is he resting in an S-Rank realm?"
Administrator #2: "No clue, he might be the only survivor!"
Administrator #3: "*Checks for his heartbeat, beating a little* He's alive, his heart rate is slowing, quickly take him to the corporation hospital!"
The administrators transport Natsuya's body to the corporation's hospital, where it rests for a few days.
Natsuya's trauma from the realm was so severe that he suffered a few days in a coma. The screaming from the temple strained his vocal cords and required recovery. The Corporation noticed this quickly and gave him the ability to access The Hunter System. After inserting it, it needed time to awaken and wouldn't turn on few days for an unknown reason. Natsuya may be alive, but he is currently in a critical condition.
