The Yellow Flowered Cat went to school to pick up Jiang Yu, because taking students off the island involved certain procedures that required a walk to the School Works Committee, which gave Zheng Qing some time to consult with Mr. Wu.
But before consulting, he had to adapt to his new body first.
Just like a person putting on a brand new piece of clothing, there would always be places that didn't fit quite right. Zheng Qing tried stretching his fingers, curling his arms, trying to shakily stand up and take a few steps.
The whole process seemed somewhat comical, and a bit disturbing.
"Your body is no different from before," Mr. Wu said, somewhat dismissively at the young wizard's cautious attempts, "you've just lost some 'parts' due to the explosion... so I provided an appropriate environment for it to return to its original state, that's all."
