The translation is mostly correct, but there are a few minor improvements and adjustments that can be made for better clarity and flow. Here's the refined version:
Qin Muyan's eyes were tinted with a faint smile. "Send someone back to the Great Wei Dynasty and bring the imperial chef who specializes in making desserts to the palace."
Wei Jue was shocked by his words.
Seriously? Just because she said it was delicious, you went all the way to bring the imperial chef.
The imperial chef felt like crying.
He felt like crying too!
Time passed by quickly. The sky had already darkened, and many young noble ladies had left. Even the chess officer began to yawn.
"Boom!"
As if it were the final verdict, Su Yingxue placed a chess piece. After the chess officer moved the piece onto the board, he rubbed his eyes. "Win... Miss Su wins this round!"
"Phew..."
Everyone present gasped!
Su Yingxue won again!
