[Rebirth at the end of the world + paid purification + base management + double strong 1v1]
In his previous life, Xu Yanqiu was the only purifier in the city. Everyone came to her for help, but no one asked her how long she could live.
She exhausted her life and fell on the purification table, only to realize that she was never a purifier, but a battery raised by the White Tower.
When she opened her eyes again, she returned to the twenty-four hours before the black rain fell. She first snatched back the epidemic prevention center left by her father, and established a rule: save emergency cases first, and settle the expenses later; if she has no lifespan, she will pay for it with supplies, man-hours, and information.
Until the polluted body Pei Du, who was wanted by the White Tower, broke in - what he owed was not a few days of life, but the entire city's 6,740 years old debt.
In this life, Xu Yanqiu wants to save people and let everyone know who should pay for this life.
