Zhang Yan, though locked in an intense duel with Lu Ge, maintained a cold and calculating demeanor in his eyes.
He could roughly surmise Lu Ge's strategy, but with a large supply of elixir pills on hand, he had no fear of exhausting his resources.
Every hour, he would take out an elixir pill, consume it, and channel the medicinal essence through his Qi Sea, refining it into energy. The 81 streams of spiritual energy within his chest rotated ceaselessly, continuously generating golden fire mysterious light. To force him to deplete his spiritual energy was an impossibility.
The two were both resilient and patient, engaging in a relentless back-and-forth as if entangled in wind and fire. After half a day, neither showed signs of fatigue or retreat, much like when they first started the battle.
