The Great Elder was well aware of his plight; it wasn't that he didn't want to withdraw his sword, but his sword seemed suddenly glued to Li Yifei's branch, making it impossible to tear apart. To stop, he had to let go, or he'd be dragged around by Li Yifei.
Li Yifei spun faster and faster, as if there was a gale whipping up on the spot. He spun in place, while the Great Elder suffered; in less than half a minute, he felt his stamina being drained.
Though skilled in Martial Arts, he was old and hadn't reached the Innate Realm. Therefore, in the end, it was all in vain. Dragged along by Li Yifei's formidable strength, the Great Elder couldn't catch his breath yet refused to let go of his sword - to a swordsman, the sword in hand is life and dignity, he couldn't abandon it.
Others watched anxiously. Some elders wanted to step in and separate them, but before they could take action, the Great Elder kicked them away.
