Six training sessions in one day, for a total of three hours straight!!
The people present—the four from the Black Tortoise Sect and the White Tiger Sect—were all experts at the Five Qi Tongxuan level. Although Sun Yunyong was a step below them, he had also recently begun his own training for Five Qi Tongxuan and understood its immense difficulty all too well.
In the Five Qi Tongxuan realm, one had to cultivate the internal organs step by step. Even when following the gentler path of gradually nourishing them with Qi, a single organ's training typically wouldn't exceed one hour in a day.
After all, the human internal organs were extremely fragile. Their recovery ability couldn't compare to that of muscles and skin. Therefore, not only did cultivation have to be done cautiously, but one also had to leave ample time for recuperation, waiting for the organs to recover before beginning the next session.
