Zheng Qing was not unfamiliar with the term 'disaster'.
In his freshman year, due to a recurring headache, Professor Yao helped him confirm that the root of his illness was a 'disaster', so he used the method of avoiding disaster to treat him, which was the Transformation Technique.
Although Zheng Qing later discovered that his headaches had another cause, the Transformation Technique indeed alleviated the frequency of his headaches to some extent, which could be considered a lucky hit.
The so-called disaster, according to the most widely accepted magical theories, is essentially a kind of information disturbance—understandable as a sudden rise of a reef in the River of Destiny, blocking the flow, creating a vortex, the force of which then acts back on this unsteady reef, either flipping it back into the river lightly, or crushing it by combining other external factors heavily.
