The night wind swept through the corridor, causing the windows to make a slight noise.
Dean Li's finger jabbed at the DNA double helix structure diagram, his knuckles turning pale from the pressure. Under the dim light, his eyes behind the glasses locked onto Lin Wan Yi like a hawk.
"Where did you see this diagram?"
His voice was low, yet carried an undeniable authority.
Lin Wan Yi didn't look at the diagram. She faced Dean Li's gaze with a calm expression, even managing a faint smile.
"Dean, I didn't see it anywhere."
Dean Li's brows knitted into a knot.
"I drew it myself." Lin Wan Yi continued, speaking neither too fast nor too slow, "Some time ago, I went to a recycling station and found an old journal brought back from abroad before liberation. The paper was brittle. It had an article about molecular structure conjectures with no diagrams, just a few descriptions. I found it very interesting, so I tried to draw it based on my understanding."
Her words were flawless.
