On the day Lu Chen left the profession, his master sealed 90% of his medical skills and left only one sentence:
"Your mother is waiting for you at the bottom of Lake Baikal. Don't use all your strength until you find her."
Twenty-three years later, he stood in front of the guidance desk of Jiangcheng Hospital, guiding the elderly like a newly graduated intern. No one knew that the moment his fingertips touched the pulse, he could see through the terminal illness disguised as medicinal gas; no one knew that every time he saved someone, he was one step closer to the destined "catastrophe".
