The spirit field wasn't destroyed or spoiled in any way. It was just that an extremely beautiful girl was standing at the edge of the spirit field, looking in much like a child staring through the window of a toy shop at the treasures inside.
Liu Qingshuang used the Whispering Secret Technique to report to Meng Yu about what had happened to the spirit field.
When this girl arrived and saw the spirit field, she became so excited she practically bubbled over with joy. She circled the field several times, like an angler who had found the perfect fishing spot or a horseman who had discovered a steed of legend. Her eagerness and desire to enter and observe were clearly apparent.
However, she firmly refused to let Liu Qingshuang take her inside. She expressed that as a fellow farmer, she could tell just how much effort Meng Yu had put into it. It was an honor to be allowed to see it, but it would be improper for her to enter.
