Operation is stopping…

Nan Hua looked at the screen in front of her and her fingers were clenched tightly for a moment before it was released. 

'So, it's still here.'

She was originally planned to hack it and it might take more than 5 minutes to crack everything, which would put those outside in more danger. But this permission was not removed and still there. 

Nan Hua understood it very well.

This was the backup her teacher prepared many years ago….

Taking a deep breath, Nan Hua calmed down again and then her fingers began to operate on the screen. After the operation was stopped, what followed next was…

"Self destruct order code 013," Nan Hua said slowly.

Di! Di! Di!
