The dew in the second half of the night was so heavy that water could be squeezed out. It trickled down the rusty iron roof of the "Echo Memorial Hall" and cast twisted water marks on the monitoring screen. It was like the infusion tube winding on Lu Xiao's arm when he was lying in the constant temperature chamber. Lin Yue was wrapped in a washed-white military green coat, and her fingertips tapped softly on the old keyboard of the console, but her eyes were fixed on the central picture - inside the constant-temperature cabin. The man's pale fingers suddenly moved, as lightly as being blown by the airflow, but she could clearly see from the corner of her eye that on the monitor connected to his brain waves, the green line that was originally as smooth as stagnant water suddenly raised a sharp peak, and then fell heavily, causing a splash of fine ripples.
