After many inquiries, Young Master found out that there were four donors whose sperm had been taken during that time.
After investigating the other four donors, the most likely one to have been confused with Young Master's was the late Second Young Master of the Reed Family, Robert Taylor.
Young Master slightly frowned and asked in a low voice, "Robert Taylor? His sperm was taken after he had died, which means someone else took it on his behalf. Have you found out who this person is?"
The Assistant replied, "Young Master, we have found out. The person who took Robert Taylor's sperm is likely to be Richard Robinson, the Third Young Master of the Robinson Family."
Upon hearing Richard Robinson's name, Young Master seemed to think it all made sense now.
He was also one of the people in the know about the relationship between Richard Robinson and Robert Taylor.
