Training consumed a lot of energy.
Xu Tui became a little flustered when he did the calculations. He had consumed two of the ten Level E Energy potions that his father had given him. From yesterday night until now, Xu Tui had consumed five bottles of Level E energy restoration elixirs.
That was 25,000 dollars.
Of course, the reason he expended so much energy was that he had some free time today. He needed to sleep during the day to recover his mind power.
However, even if he started lessons during the day and trained for one to two hours at night, Xu Tui estimated that he would consume two to three bottles of Level E energy restoration potion every night.
Three bottles cost 15,000 dollars.
At this rate, he would spend all his money in two months.
