In order to save his seriously ill sister, courier Lin Mo gritted his teeth and signed a "brother-in-law" contract and became the contractual husband of Bingshan CEO Su Wanqing, suffering all the humiliation. Until one day, he delivered a mysterious package with the addressee "Lin Mo". At the moment of signing, majestic memories poured in - that was "myself" who had reached the top in the blood and fire of the parallel world. Since then, his express delivery system has become a bridge connecting all worlds. In the main world, he is a useless son-in-law that everyone despises; secretly, he keeps "signing" for "his" inheritance from countless parallel worlds: the muscle memory of a martial arts master, the business acumen of a financial giant, the war art of an interstellar commander... When the wealthy families in the main world bully him too much, when his wife's family is the conspiracy to seize power, The plot came to light, Lin Mo silently clicked on the order to be delivered marked "SSS level" in the system, and whispered to himself: "This time, should I deliver 'Doomsday' or 'Myth'?" Su Wanqing, who was just using him at first, looked at the man in front of her with an increasingly profound aura, and for the first time she felt uncontrollable panic.
