In 1977, Zhang Feng had both kidneys removed alive by his adoptive elder brother on the operating table. Only at the point of death did he learn he was not born to the Zhang family. Opening his eyes, he was reborn back to the spring when he broke his leg. Holding the ancestral ring left by his biological parents, he unlocked a spirit spring space; the liquid in it healed his injured leg, and the space preserved all things fresh. Using this, Zhang Feng sold game, stockpiled textbooks, ventured into the black market, and grew rich while rising against all odds — he slapped back at his cruel adoptive family, stood alongside educated youth Lin Wan'er to prepare for the college entrance exam, and swore to reclaim every injustice from his past life with interest!
