At this moment, Xu Yun, dressed in everyday attire, was mistaken by a scholar with the surname Ou as a member of the numerical calculation group, who then asked:
"Brother, what are your insights?"
"Me?"
Xu Yun paused slightly, and after confirming that the question was directed at him, he pondered for a moment and said:
"I dare not claim any profound insights, but I can barely judge the correctness of the direction of the problem-solving."
The scholar with the surname Ou exchanged a glance with the scholar surnamed Zou. They did not underestimate Xu Yun's age, as anyone who could enter this courtyard was no novice:
"Problem-solving direction? Please, brother, elaborate."
Xu Yun thought for a moment, gesturing the shape of a combustion chamber:
"According to the engine's design drawings, it is known that the intake port and the interface are level."
