Lin Suqing could clearly sense that Mr. Wu from the Tianxiu Institute already harbored bias against him, yet he still managed to maintain a smile with neither servility nor arrogance, "Thank you for delivering the message in person, sir."
He, of course, knew they hadn't come just to deliver a message; there was certainly a more pressing purpose, but how could he call them out on it when he knew they harbored hostile intentions? There would be days ahead when they would have to see each other, not to mention that this man was the esteemed Institute Master.
But those Institute Masters did not appreciate his discretion, especially Mr. Wu, who took it as a deliberate mockery. As a result, Mr. Wu made their stance clear, but without directing it explicitly at Lin Suqing.
