What episode does Xiaofeng wear glasses at the beginning of "The Legend of Pinball"?

Maple and thunder fire continued on the mountain, and all the food was only half a baked sweet potato. Just as they were about to share, they saw an old man with a white beard lying in the middle of the road, starving to death. Xiaofeng and Lei Huo endured hunger and kindly gave the baked sweet potato to the old man with white beard. The old man thanked them, knowing that they were going to find the marble fairy, guiding them to cut corners and saying that he would go with them. Xiaofeng was very happy, but Lei Huo thought the old man was mysterious.

The weather in Zhuxian Mountain is unpredictable. It suddenly began to snow halfway up the mountain. They can't escape. Xiaofeng injured her arm to save the old man with white beard. They were trapped by the big ice, and the thunder fire fired marbles with a flaming lion, but the ice just kept falling, and someone needed to send marbles on the other side to balance it.

Xiaofeng's arm was injured, and the marbles playing chasing birds deviated too far; The old man with white beard picked up a barrel on the ground and handed it to Xiaofeng. Xiaofeng had a brainwave and installed a first-class gun tube on the bird chaser, which made up for his shaking hands and fired accurate marbles. Xiaofeng and thunder fire broke the ice together; Xiaofeng wondered how there could be such a suitable gun barrel for chasing birds on the ground.

They finally found the marble fairy's small stone house on the mountain, outside which were the Tsing Yi boy and the girl in white. Xiaofeng knew that the bearded old man was Haji, a marble fairy. Xiaofeng was surprised that he accepted him as an apprentice so easily. In fact, the previous vigorous fighting, giving food and crossing the snow-capped mountains were all tests for Haji, but he humorously emphasized that he was an elusive fairy. In fact, he felt the power of "marble fighting spirit" in Xiaofeng and Lei Huo, and Jack, a young boy in Tsing Yi, has been helping the master to inspect him.
