At nighttime, Jacob had been at Water Mediation for three hours, and he was quickly approaching the fourth hour.
Not only was he completely fine under 30-G force he wasn't feeling any urge to breathe. On the contrary, when the oxygen starts to enter his body and pours on its own like it usually does, the suffocation of holding his breath no longer irritates him.
Especially when the third hour started, the oxygen's absorption was getting stronger. With his Epic body, Jacob could feel it as clear as day that something was stirring inside him as he performed the Water Mediation.
Furthermore, the water stream no longer even budged him as he was completely attached to the river bed now.
Just like that, 4th-hour passed, and then the 5th, and finally it was the 6th hour, and now Jacob was under 60-G force, and the water was now started to swirl around him as the oxygen absorption was now as clear as day, and even faint cold steam was starting to rose from the river stream.
