Chapter: 253

Lingling "cut": "Of course, do you want to show you your ID card?"

The courier nodded: "I want to show me the certificate."

Lingling was directly gagged, unable to speak for a long time. Ye Chen showed his work ID to the courier, and he handed over the mail to Ye Chen. There was no sender's information on the mail, and he walked into the research center to open the mail, and inside was a small blood.

Ye Chen's intuition told him that this blood was unusual, and the enthusiasm for scientific research quickly occupied his brain, so he immediately began to study, so excited that he completely forgot the time.

It turned out that his guess was right, and the results of the experiment surprised and delighted him.
