"You think you can stop me? You are simply overestimating your capabilities!" Zuo Ci glared angrily: "Khalid, you have been corrupted by the power of evil. We must stop you today!" After that, he waved the soul-suppressing flag, trying to disrupt Khalid's mind. Khalid snorted coldly and waved the bone blade in his hand. The Witch King's army instantly dispersed and surrounded the four people in a fan shape. The soldiers wearing meteorite armor had blue flames beating under their faceplates, exuding cold murderous intent. Fairy Qingyin was the first to take action. She raised her jade hands lightly. Although the guqin was destroyed, she condensed invisible sound waves with her fingering skills and shot them towards the Witch King's army like a sharp blade. Wherever the sound wave went, cracks appeared in some soldiers' meteorite armors, and the blue flames flickered. Master Ziyang waved the green bamboo, and the remaining bamboos burst out with fierce sword energy, cooperating with the sound waves, and rushed towards Khalid. Khalid did not dodge, however, and swung his bone blade, blocking the sword energy one by one, causing sparks to fly everywhere. Taoist Master Kunlun activated the power of the stars. The stars twinkled in the sky, and several meteors dragged their long tails and fell towards the Witch King's army. With a powerful impact, the meteors made large craters in the desert. Many soldiers were hit and dissipated into black smoke. Zuo Ci took advantage of this opportunity and used all his strength to control the soul-suppressing flag. The runes on the soul-suppressing flag glowed brightly, trying to pull Khalid's soul out of the control of the inner demon. Khalid's body trembled slightly, and there seemed to be a sign of struggle, but soon, the power of the inner demon took over again. He let out a roar, and the black light on the bone blade surged, slashing towards Zuo Ci. Zuo Ci quickly dodged, and the bone blade scraped against the corner of his clothes, leaving a deep mark. In the fierce battle, the four gradually felt powerless. Their mana had been exhausted in the previous battle with the men in black robes. At this time, facing the crazy Khalid and the Witch King's army, the pressure was increasing. The strong wind of the desert carried the gravel and blew across the faces of Zuo Ci and others like sharp blades. The protective barrier barely supported by the four people was crumbling like a candle in the wind and rain under the impact of the Witch King's army.
