It took Jin hours as he strained his eyes and body to prepare everything under cover of darkness. As he placed the traps, he already planned for the next trap should one failed or the other was skipped.
Jin did not rummage through the abandoned temple for fun, and with the experience of a Dungeon Maker, the generation and execution of ideas was smooth which lead him to believe that he was successful creating the traps to the best of his abilities. However, all this could not have been done if not for the partial moonlight shining through the forest to illuminate the place, else Jin doubted he could do anything until the next day.
He was not very sure if he was going to make it through this particular 'life', but at the very least, he had marked the locations from the entrance of the bamboo forest via the river and remembered specific landmarks to reach this particular temple again.
