Chapter 324 The Original Sin of All Tragedies

"No, no, sister, I don't want your bone marrow! I... I just sensed you were in distress, that's why I came over..."

Yan Jinsi had barely heard his elder sister say the match was successful before he hurriedly interrupted her without fully understanding the meaning—

The anxious Jinsi paused, puzzled, and looked up at his sister and brother-in-law, who were leaning in close together.

Yan Jinsi blinked, asking hesitantly: "Umbilical cord blood?"

Don't blame him for being so confused, it's because the term Zhang Shan Ni used really bewildered him. It's only the late 1970s after all, and medical science has not yet advanced to the research of 'umbilical cord blood'.

Even if there were studies underway, results had not yet emerged. So, not to mention military doctors, even the public and private hospitals outside had no idea what 'umbilical cord blood' was.
