Hacker's Rise 21

Hacker Tessa fell into a coma after inhaling a new type of poison released by a software and accidentally traveled back to the late 1990s, possessing the body of a wealthy young master named Jonny. Jonny was the second son of the local wealthy Owen family, but due to his weak personality and frail health, he was controlled by his adopted older brother. Upon waking up inside Jonny's body, Tessa decided to leverage her knowledge from the future to take down her enemies, successfully dismantle the new poison manufacturing group, rise to become the new master of the Owen family, and marry a genius doctor.
