Let's attack!

Xu Beihan was frustrated and irritated. Not only because of the murder cum suicide case also because of the fact that their department was now considered as the lowest performing department and there might be chances that their department would be dissolved soon. 

 Even if they were working on the case in the background they were unable to inform the higher-ups. 

 In case if they do so and are unable to turns result things might turn worse. And if luck favors them and they get results there will always be a threat of leaking out information. 

Xu Beihan was on a tight spot. 

 As if things were getting piled up on him. He was still unable to find out the person who helped Zhi Ruo at that time. 

Hearing Xu Beihan gives permission, Zhi Ruo entered the cabin and greeted him, "Senior!"

Looking at Zhi Ruo standing all safe and sound in front of him, his heart relaxed and all of his irritation and frustration went away.
