Lin Shen's energy depletion was far greater than that of the Ximen Swordsman, but he didn't care.
The Ximen Swordsman wanted to wear him down, but he likewise wanted to deplete the Ximen Swordsman.
No matter how effortless borrowing and converting force could be, it ultimately still required some expenditure of strength and stamina.
If the Ximen Swordsman had faced someone other than Lin Shen, trading two or three percent of his own battle damage for dozens of times that of his enemy would indeed assure victory without loss.
However, Lin Shen was willing to trade dozens of times his own battle damage for merely two or three percent of the Ximen Swordsman's; Lin Shen could endure a loss dozens of times greater, while it was uncertain whether the Ximen Swordsman could last to the end with just a two or three percent loss.
What Lin Shen was banking on was his profound foundation and strong endurance.
