I'm a food delivery driver, and from the start I obtain a divine weapon to fight off an invasion by world-ending monsters. In the third year before the River Styx era, a seemingly endless horde of unknown creatures attacked this world. Everything they encountered was devoured. Cities and people alike were ravaged in a very short time, and countless lives were lost. At this desperate moment, a small number of humans suddenly awakened different supernatural abilities and began fighting the monsters later known as the Jiugao monsters, named after the city of Jiugao where they were first discovered. They achieved some victories, slowing the monsters' gradual encroachment on human territory to some extent. But as the enemy's attacks grew more ferocious, by the final year before the River Styx era, the surviving humans had all gathered on the western bank of a river called the Huangtang River.
The humans who had awakened their powers also gathered there, making it their base as they continued to resist the Jiugao monsters. Unfortunately, as the monsters' attacks grew increasingly fierce, countless awakened fighters fell one after another, and the pressure on the defenses west of the Huangtang River steadily mounted.
At last, during an exceptionally fierce assault, just as the Jiugao monsters were about to break through the Huangtang River defenses and invade human territory, an awakened fighter named Qi Ming stepped forward. At the cost of her life, she created a barrier across the river, separating its western and eastern banks and preventing the Jiugao monsters on the east bank from crossing over in the near future. It is said that she lost her physical form and became a great bird, secretly protecting humanity.
