"Travel + System + Beast Ear Girl + Evolution + Single Female Protagonist + Classic of Mountains and Seas"
In this world ruled by orcs, humans are regarded as unfinished embryos and cannot awaken their bloodlines.
Duan Yunian traveled through time and became a human son-in-law. He originally thought he would survive by clinging to the thigh of his fox demon wife.
Until he awakened to the [gene editing system].
As long as the blood of all beasts is extracted, the genetic sequence can be analyzed and the "evolution serum" can be produced!
"It is detected that the host has obtained the blood of the white tiger. Should we consume 500 evolution points to eliminate the 'bloodthirsty rage' side effects and integrate the 'king's pressure'?"
"It is detected that the host encounters a strong enemy. Should we urgently synthesize the [Falcon Eye + Rattlesnake Venom] temporary serum?"
...
"You said humans can't practice?"
Duan Yunian pushed up his reflective glasses, and the needle in his hand shone with a faint blue light.
"In my genetic map, there are no useless genes, only quacks who don't understand genes."
When the orc laughed at him for being a humble human being, Duan Yunian silently took out the syringe:
"I heard that your bloodline is very strong? Let me study it."
As a result, a frightening "blood-draining demon" appeared in the orc world where the weak and the strong prey on each other!
This is very beautiful, waiting for the update
