Arknights: Starting with Rainbow Six

[System + Leveling + Rainbow Six + Harem + Anime] Zhuang Xiaolin arrived in a world where he knew nobody and nothing. He couldn't understand a word spoken here, and as a result, he was bullied by the locals, even nearly starving to death. At the critical moment, a voice calling itself the System saved him, and even provided him with a world-class counter-terrorism unit—the Rainbow Six squad. After a period of development, Zhuang Xiaolin obtained the language of this world from the System, but after acquiring the language, Zhuang Xiaolin began to feel that this world was becoming more and more similar to the Arknights he knew! Why is this becoming more and more like the Arknights I know?

In the time that followed, a mysterious squad swept across all of Terra. They had loyal believers, steadfast warriors, and indomitable spirits. Like a sharp spear, they pierced through this dark world. From Ursus in the north, Yan in the east, Columbia in the west, Iberia in the south, and Victoria in the center, their name was known to all, and their power was unstoppable. With their lives, they let all of Terra catch a glimpse of dawn. Though chaos and filth abound, a single ray is enough to awaken the entire continent. Welcome it—a brand new era has arrived!
