Jin was unsure if he should feel relieved about the State Agent's ignorance on the matter, but he decided to play along to learn the extent of how much Kong Rong actually knew. Perhaps, he might not know of the existence of the System at all, and that itself would be a great relief for Jin.
"I did not expect the Royal Zodiacs or even the Ministry of State Security to even know- hmm no, you surely know of our existence. More like wasting resources and allocating manpower to track our existence, if what Kraft said is true about you. We are basically dead in your eyes since we have no strength nor power to fight you guys. Why do you bother to look us -erm me up?" Jin queried even though he initially wanted to play dumb.
Yet, knowing Kong Rong, it was useless to do so and might actually be counterproductive. Thus, Jin decided to acknowledge the fact that he was indeed part of the rumoured Royal Panda Clan.
