Arknights, the Commander Leads the Team into Terra

As a high-dimensional creature, Chu Yuan had been looking forward to the day of retirement for a long time. When he was happily imagining his retirement life in the high-dimensional space, he was "kicked" by his superiors and took his "retirement gift" - a system, directly to another time and space. Originally, Chu Yuan was quite excited when he heard his superiors said that he was going to be sent to the "World of Terra". After all, as a member of the high-dimensional service team who had traveled to dangerous areas at different latitudes for many years, he would not have to live a wonderful life in that place where big guys fight each other, tearing apart Tzeentch with his hands, kicking Tzeentch, burning Nurgle alive, and marrying Slaanesh! Not to mention more, Huang Pizi had to consider his record of killing the world of Cthulhu with his cold dragon spear. Then he heard the broadcast the moment he landed: "At present, the integration movement has been completely repelled by the Ursus Empire. Citizens of the Ursus Empire, the integration movement is just a bunch of rabble. The relevant departments have been prepared to deal with it. Please don't worry..." Wait a minute... Integrated movement? Which Terra is this? PS: This is my first time writing, so my writing is not good, so please bear with me. In addition, the author tends to go crazy, Froststar must be saved, and it remains to be determined whether Mephistopheles will survive.
