Although this method didn't affect the Flying Swords, it greatly increased the consumption of Spirit Power when Dong Tianyu commanded the swords. Normally, controlling swords didn't consume much Spirit Power, but during prolonged battles, any slight increase would be exponentially magnified as the battle dragged on.
Faced with such a situation, Dong Tianyu felt somewhat helpless. Ever since the calamity struck and he embarked on the cultivation path, it seemed he had never truly fought with all his might. Every battle either ended in an overwhelming victory or he easily reaped the fruits of victory through various means.
Truth be told, Dong Tianyu had never personally experienced such a war of attrition.
Regarding such evenly matched battles, Dong Tianyu deeply wanted to avoid them. Therefore, when he noticed that his Spirit Power consumption was about to exceed half, Dong Tianyu somewhat unethically fetched numerous explosives from his Storage Space.
