High in the misty mountains, Monk Tang Sanzang traveled west to find sacred books of wisdom. By his side were his loyal friends: the brave Monkey King, Sun Wukong, who could chase away any monster; Pigsy, who loved food; and Sandy, who carried their bags. They journeyed together, guarding one another through the long road ahead.

In a dark cave nearby, a wicked white-bone demon watched them through her crystal mirror. She longed to catch the monk, believing that consuming his essence would grant her eternal power. “Those travelers look tired,” she whispered. “If I trick them, they’ll never see me coming.” Her eyes flashed with wicked light as she began to change her form.

Moments later, a pretty village girl appeared on the mountain path, carrying a basket of fresh buns. “Dear travelers,” she called sweetly, “please rest and share my food.” Tang Sanzang smiled kindly, but Wukong frowned. His golden eyes saw through lies—and he spotted a faint shadow of bone beneath her face! With one swing of his magic staff, the girl vanished into a swirl of white smoke.

Tang Sanzang gasped. “Wukong! Why did you make an innocent girl disappear?” “She wasn’t real, Master!” cried Wukong. “That was a demon in disguise!” But the monk shook his head sadly. “You must learn compassion, not anger.” The Monkey King sighed. His master didn’t believe him. Still, he stayed to protect him.

In her cave, the white-bone demon stamped her foot. “That monkey ruined my plan!” She turned herself into a frail old woman with a walking stick and went out again. “Kind monk,” she said, pretending to cry, “have you seen my daughter?” Tang Sanzang felt sorry for her. But again, Wukong’s sharp eyes gleamed. He spun his staff—and poof!—the old woman disappeared into another puff of smoke.

“Enough!” said Tang Sanzang. “You have made two innocent people disappear!” “Master,” Wukong pleaded, “it’s the same demon! Please believe me.” But the monk was gentle and too kindhearted to see evil’s tricks. Wukong bowed low. “I’ll protect you anyway,” he said quietly.

The demon grew angrier still. “He’s too clever! I’ll try one last time.” This time, she turned into a white-haired old man with kind eyes and a cane. When she approached, even Pigsy said, “She looks harmless, Brother Monkey.” But Wukong’s magic sight saw through her once more. He leapt into the air, twirled his staff, and broke the spell—the demon’s true form, pale and smoky, appeared for an instant before vanishing with a wail.

Tang Sanzang was frightened and angry. “You’ve done it again! Leave us, Wukong. I cannot travel with someone so violent.” A golden band around the Monkey King’s head tightened painfully—punishing him for disobedience. He bowed, his heart heavy. “Master, I only wanted to keep you safe.” Then he flew away on a cloud, disappearing into the red sunset.

Days later, without Wukong, the road grew quiet and lonely. One night, a cold wind blew—and the white-bone demon returned! She swept down like a shadow, trapping the monk in her claws. Pigsy and Sandy fought bravely, but her magic was too strong. Tang Sanzang finally understood—his Monkey King had been right all along.

Far away, Sun Wukong heard the monk’s cry. He rode his cloud back through thunder and storm, his golden eyes blazing. “Demon!” he shouted, striking with his shining staff.

With one final flash, the white-bone spirit was gone forever. Tang Sanzang knelt before him. “Forgive me, Wukong. I doubted you.”

Wukong smiled. “That’s all right, Master. A true friend protects, even without thanks.” As dawn rose over the mountains, the travelers set out again—together, wiser, and stronger than before, continuing their journey to the west.
