After Running Errands for a Transmigrator, My Homeland Recruited Me

Some people say running errands is undignified and dishonorable. Others say errand runners get bossed around and treated with no respect. And some say there's no money in running errands. Ying Shu has only one thing to say: Pah! After graduating, Ying Shu joins the ranks of errand runners. Then the System upgrades, and her clients become people who transmigrate between worlds. She runs an errand for a transmigrator from the cultivation world: deliver medicine to his wife, who has ALS... [Ding! Congratulations on completing the mission. You've received a Marrow-Cleansing Pill from the transmigrator from the cultivation world.] After her family takes it, they're all in excellent health and learn everything with ease. She runs an errand for a transmigrator from a disaster-ravaged world: fight for custody of his daughter... [Ding! Congratulations on completing the mission. You've received ten thousand taels of gold from the transmigrator from the disaster-ravaged world.] She immediately pays off her debts, escapes poverty, and becomes a billionaire. She runs an errand for a transmigrator from an interstellar world: restore severely polluted land to fertility and bring the earth back to life. [Ding! Congratulations on completing the mission. You've received a biological robot from the transmigrator from the interstellar world.] She turns around and hands the robot over to her country, sending its technological development into overdrive and making it the world's leading tech power. The country's leaders are astonished, and other nations are green with envy. From then on, she becomes the greatest errand runner of all, traveling between worlds to benefit the people and serve her country.
