Lone: The Wanderer - Chapter 33Book 2: : Level-2 Contract and The Tunnel

In a world ravaged by radiation and the remnants of war, Dylan is far from a classic hero. A lieutenant with a tainted past, he's just trying to survive the ruins of a dying world... until the day he wakes up bound and surrounded by the mutilated corpses of his comrades.Captured by monstrous creatures, he soon realizes he’s been transported to another world. A world far more dangerous, far more brutal—where only the strong survive, and even monsters are hunted. Saved in extremis by Maggie, his commanding officer, he begins a desperate escape. Their only hope may lie in their encounter with Élisa, an elf abandoned by her kin, and their discovery of a mysterious power: anima gems—stones imbued with spiritual essence that can enhance body and soul, and unlock the path to awakening.No One under 18 admitted

Wei Lan accidentally transformed into a cannon fodder girl of the era. She was dissatisfied when she went to the countryside for her brother and broke up with her family.

Because he was greedy for the male protagonist’s “beauty”, he was framed by another cannon fodder’s female partner, and successfully married a second-rate man in the brigade. In the end, he died in a foreign country. It can be said that he was a master of death!

Wei Lan, who is familiar with the plot, said who the male protagonist loves! Please let me be beautiful alone!

(The heroine has a delicate setting, she doesn’t like to stray in, her daily purpose is: sweet, sweet, sweet!)

Note: There is another male protagonist, not the male protagonist in the original book.
