Whether it was Wu Ming or Baili Xia, they had immense trust in Bei Fengjin's medicine-making skills.
So, Bei Fengjin took out this bottle of medicine to conduct a blood relation test for Baili Xia.
The two were fully aware that this medicine could accurately determine whether there was a blood relationship between them.
Ancient methods of blood relation tests are definitely unreliable, but in Bei Fengjin's hands, there would be no mistakes.
It was Baili Xia's first time witnessing the process of two people recognizing their kinship.
After a drop of blood was taken from her fingertip, Bei Fengjin also took a drop of blood from his own.
The two drops of blood fell into the glass bowl and quickly merged together.
If this were ancient times, the matter would probably end here.
But now, they are in the modern era of advanced science.
Bei Fengjin took a pipette, extracted most of the merged blood, and also took a drop of solution from the medicine bottle.
