The serum is the genetic database on the right -clicking of the experimental desk

Then burn the attribute you want through the sequencer (the sequence after the PCR processing is from extremely weak {16 -minute sequencing} to strong {4 minutes sequencing} can shorten the sequencing time and so on)

This will appear in your database you will have the attribute you have burned

Right -click the experimental desk to open the database to obtain the attribute you burned through the empty serum bottle

Note: Take one air hemorrhage bottle, and multiple air blood bottle cannot be extracted directly

Select an empty blood bottle to drag to the attribute you want to left -click to get the corresponding attribute

The attributes obtained can be used to increase the number of times through PCR
