Dr. Gu was one of the doctors alongside Devyn Nam who was part of creating the drug. All of them worked for Lavro Yanovich. At first, Dr. Gu was not aware of what they were formulating but because he was threatened, he did not have any other choice but to cooperate. Eventually, he just treated it just like another project. But unlike the doctor who got away, he was there the entire time until the drug was finished.
They were all paid with a hefty amount and it made him think that he was compensated more than enough. So even though he knew the effect of the drug, he did not bother.
Daniel's expression turned from shock to furious in a split second. "What?" He bit out. The look on his face scared the doctor out of his wits.
