Deliveryman from Two Circles: the Country Forces Me to Support Eight Hundred

Zhou Dayong, 46 years old, owner of a car repair shop. The mother is paralyzed, the wife is getting divorced, and the daughter runs away with Huang Mao. Forced by life to reach the rooftops, he accidentally awakened the [Two Worlds Traveling System]. Opposite is the Sihang Warehouse built in 1937. The national soldier with a broken arm was crying: "Is there any medicine? I can give it to someone who stutters..." Zhou Dayong handed over his mother's iodophor in exchange for 5,000 yuan. His eyes lit up - this thing can make you rich! Antibiotics, instant noodles, body armor... He resold like crazy, counting the money until his hands cramped. Until one day, the cephalosporins he passed on were seized by the Japanese army. Japan's Super High School followed the lead and locked the coordinates of the crossing. They are preparing to travel in reverse and capture the "future people" alive. Late at night, while Zhou Dayong was counting money, the door of his room was kicked open. "Ministry of National Security! Do you know that you almost put the Japanese into 2024?" The officer patted the table and gave two options: Either cooperate with the country to clean up the mess, or be punished with treason. Zhou Dayong was scared. From then on, he was "recruited" by the country and forced to become a material courier between the two worlds. Xie Jinyuan asked him: "Who are you?" Zhou Dayong smiled bitterly: "An unlucky guy who originally wanted to make money, but now he is forced to save the country." Our ancestors shed their blood to protect our country, and we are forced to save our ancestors. This time, with the support of the country, not one of the eight hundred heroes can be missing!
