Quickly Wear the Supermarket System to Rejuvenate the Country

[Quick travel + supermarket system + no CP + no holy mother + daily direction + country] Chen Jinxi has just finished the college entrance examination and plans to travel with his friends. During the trip, a rolling stone accidentally binds to the supermarket system 315. What kind of otherworldly journey will they embark on? 315: "Host, we need to refuel. Exchange the items from the supermarket for the refueling system, and we can go home." As a new era youth who grew up under the red flag in the 21st century, Chen Jinxi has always believed in the country unswervingly, and as flower growers, the people naturally want to revitalize the flower growers. Ancient Plane: In an era when famine and plague were raging, people were in dire straits. We used modern technology to exchange precious cultural relics such as the animal-headed agate cup with a history of more than 1,000 years ago, the red gold walking dragon, and the secret color porcelain of the Five Dynasties. Interstellar plane: never-before-eaten delicacies and the mysterious Chinese civilization have given us plasma torpedoes, transmission of light speed, and 2nm lithography machines... There are also the apocalyptic planes, the Republic of China planes, and the immortal cultivation planes... Waiting for them to explore. The heroine is kind but not a virgin. The heroine and the system have a win-win relationship. The system will train the heroine before she travels through the plane. The heroine has cooperated with the country from the beginning (the heroine's father knows the top officials of the country) and there will be a live broadcast later. (The heroine has a golden finger and occasionally makes jokes. There are very few villains and they get offline quickly. Everyone is a good person.) This is the author's first time writing a book. If there are any mistakes, you are welcome to correct them.
