He had trained for three hours under twenty times gravity.

"This round of training used up a total of thirty-eight kilograms of energy fluid..."
Su Yuan glanced at the empty test tubes before him.
So-called energy fluid was the essence energy contained within various potent and ancient medicines, extracted through external means and refined into liquid form.
This was not only convenient, but also easier to absorb.
After all, those potent and ancient medicines contained impurities. If swallowed directly, the waste and impurities inside still had to be expelled.
When he had first begun cultivating, Su Yuan had not had the means to refine ancient and potent medicines, so he could only swallow them directly. Now, there was naturally no need for such trouble.
