Gao Wu's Rebirth: I Have Dual Systems That Will Push Me Through the Ages

Dual system + urban high martial arts + qi and blood + cool writing + decisive killing + upgrade flow [Introduction to the work] When his father hid the handkerchief that coughed up blood into the pillow, Lin Nan's rebirth memories were finally integrated - in this world of high martial arts, Bitcoin is worthless, and blood value is the hard currency. And he only has 0.89 Calories, a "martial arts waste" that can't even meet health standards. The martial arts test was 87 days away and the registration fee was 10,000.

The class teacher said he was destroying his future, and his classmates laughed at his stench, but no one knew - the monster cores accumulated in his system space were enough to buy half a street; underneath his 8.1 Cards of surface energy and blood, he had real combat power comparable to the sixth level of a warrior! On the day of the martial arts test, the detector exploded in front of him. The principal asked tremblingly: "How... How many have you killed?" Lin Nan wiped the wet blood on the knife and looked towards the hospital: "Not much, just enough to exchange for a pill that saved my father's life."
