Darton Thompson was making a phone call to Harold Hannes.
He knew that contacting one more person would possibly expose what he had done.
But he couldn't suppress the panic in his heart.
If it were discovered what he had done, maliciously causing the future princess consort to become infertile, then his life would certainly be ruined.
So, he had to confirm something, to make sure he was completely safe.
Harold picked up his phone quickly.
"It's rare for you to call me," Harold said happily on the other end.
However, Darton went straight to the point.
"Senior brother, I've been thinking about something since I got back," he said in a coquettish tone.
"What's that?" Harold asked.
Darton immediately replied, "It's about the drug you guys developed. I want to ask, will the lab rats have any adverse reactions after being injected with that drug?"
