Kraken

According to Anna, the discovery of the ruins was a coincidence.

At first, the search team went to investigate a cave in the deep mountains, but they fell into an underground river by accident. The search team was a Knight, so they didn't die in the undercurrent. About ten minutes later, they were washed by the underground river to the valley.

At that time, the search team was also injured and was ready to leave. However, when he reached the valley, they found that it was foggy, but he was not afraid and was ready to go through directly.

And then he got lost.

He was in a daze and didn't understand what was happening. When he reacted again, he was outside the valley. In the fog, there seemed to be snake-like creatures rushing toward him.

Although he was in a daze, he still subconsciously ran away. He ran out of the valley and finally hid in a rock to avoid a giant snake.

"Giant snake?"
