We are aware that the flow of water in the training room at its highest level is faster than light speed. A flow speed of more than 299, 792, 458 meters per second (m/s) and a moving target at such a speed are required for all voiders with archery skills to master in the future.
Jin Dae's start of V01D's training begins at the first level, which is LEVEL 0, with normal gravity set at 50 kph for water flows. She has aced her training.
As far as Jin Dae was concerned, she was at level three of the archery training room. LEVEL 2 of the archery training room will have its gravity set at 500 kph water flows. A ten-fold qualitative increase. At LEVEL 3, there is another hundred-fold qualitative increase.
