Inventory trick

"How much time is left?" Li Ling asked as he looked at his sister. 

Li Ying looked down at the timer on her screen before she answered, "Barely six minutes left." 

Li Ling gulped in worry, "Let's go. I'll drive." 

Li Ying and Liang Feng nodded in unison as they followed after Li Ling who had already turned to leave the place. 

"I don't know man, I'd prefer to use my own car but if you are that eager to drive me-" Tian Xifeng stopped as she saw that everyone had already left her behind, "Damn it... At least wait for me!" She shouted as she ran after him. 

Huang Zhi Juan sighed as she saw everyone leave. She was the only one left behind with the rest of the staff who worked in this research facility. She looked around and felt hopeless. There were no computers or systems working properly in the place and she was sure that even if she went outside the research center, the condition would be the same.
