Chapters 319-321 A Stone's Throw_5
Xin Yun had a reason for carrying all four Treasure Swords on his person: three days ago, he had originally planned to take only one, the Executing Immortal Sword. However, over the past three days, after receiving the insights from the Four Great Sword Souls, Xin Yun had come to understand that while using the swords separately did not reduce their power, the energy consumption was particularly immense.
If one used a single sword, a vast amount of energy was required to sustain it. But with all four swords together, once one sword was wielded, the other three would automatically cycle through earth, water, fire, and wind to replenish energy; Xin Yun only needed to provide a trace of energy for guidance.
