Gene Lock Is On: I Want to Ascend Scientifically

In this world, genes are divided into grades, and bloodline almost determines destiny. Excellent people are born to sit in offices. Low-class people are born to farm, mine, and work as consumables. Destiny? Ha. The day my sister died, the CBI people were laughing. Ling Han didn't smile. He just memorized every face. He has a reagent in his hand - given to him by the old beggar before he died - that can rewrite genetic talent. Is there any danger? Smiles always appear on the faces of superior people. Ling Han didn't care about anything anymore. He just wants to make this world... Blood debts must be paid with blood. Change the rules of the entire world.
