Past Life Returner - Side Story 2: That Day Martial Law, Kyeong-Il

Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

An intelligence error caused the Third Fleet to face an ambush. In order to divert his enemies, the imperial admiral drove the starship alone into the meteorite band, and his spiritual power fell into a coma under heavy blows.
With the help of mystical powers, he began to experience reincarnation again and again to repair his spiritual power.
Therefore, after “death”, when he opened his eyes again, he became a blind and frail young master who’s parents both died and was about to be stripped of all his property by his uncle and aunt.

He Yan: ….first get rid of this group of bad relatives then talk (╯‵□′)╯︵┻━┻

Wait… This patriach, you’re clearly not part of the plot?

- Description from Novelupdates

Guo Miao, the national treasure of the Empire, committed suicide after completing a certain grand project. Everyone had theories about her motives, but no one was aware that she was a reincarnation and had simply ended her own life because there was nothing left for her to do. She did not expect to reincarnate back to her past life when she discovered that she was the Guo family’s real rich daughter. In her last life, she did not turn down her parents who came for her, only to find that her decision left her in the abyss.

Not only did her parents play favorites, but their fake rich daughter was also ruthless, framing her for a murder and isolating her, then leaving her to rot in jail while her stepfather died from depression. Now that she had reincarnated, she no longer sought familial warmth—only survival for the sake of those who truly loved her and to live her life! She earned countless honors and innumerable scientific discoveries by turning over a new leaf.

Everyone who used to belittle her now regretted life, bawling as they begged for her patents. She coldly watched as they humiliated themselves and snapped at them icily: Dream on! In this secular world, she was the goddess to all and the most coveted person of every rich kid in the Imperial Capital. A certain man: The proudest thing I’ve done in my life is winning her love!
