First Day

Using the microscope he was familiar with, Ling Ran gently connected the small part of the patient's thumb together to the rest of her thumb together.

If a layman did not consider the importance of a fingertip, then finger replantation would most likely just be a very small surgery in that layman's eyes, since the surgeon was really just suturing the finger together.

However, in the world under the microscope, the difficulty of a finger replantation was like an architecture trying to reconnect a building that was broken into two.

And the surgery would only become more complicated if the surgeon wanted to ensure that the replanted fingers retain their dexterity.
