Here's a recommendation for one of my older books, "This Master Is Heartless"
Synopsis:
Monday: The containment at the Fearfish Hatchery has failed. Defense Division staff, report to the site with heavy combat gear.
Tuesday: Engineering has submitted a weapons test request. Prepare for disaster response.
Wednesday: A decontamination operation will be carried out in the underground ecological zone. Wear biological protective suits before entering.
Thursday: Yesterday's incident has been confirmed as an act of corporate espionage. The test request for the new artillery has been approved. Testing will take place at the third branch of Thor Industries.
Friday: The polar research station has come under attack by fiends. Employees receiving this notice, assemble at the landing pad within fifteen minutes.
After three years, Su Qiu had become a leading candidate for head of the Defense Division. He hoped that once he became a leader, he could climb the social ladder and enjoy a wealthy, comfortable life.
But he was always wondering whether he would live long enough to see that day.
Perilous field assignments, horrifying experimental subjects, and deranged colleagues who kept blowing up the lab...
In this brutal workplace, the only things that offered any warmth were the paycheck in his hands and the salary card in his pocket!
