Ren Suo still didn't go to take a look at Zhao Zili in the end.
He even began to vaguely regret why he had entrusted Xie Qiansi to investigate.
Luckily he didn't use the Tactical Bureau system to conduct the investigation, or else he would have left traces and would be in trouble now. However, things aren't much better now—at least Xie Qiansi and his uncle are now aware that 'someone is looking for Zhao Zili'.
Ren Suo could only say that Zhao Zili had swindled his money and the like, which, given Zhao Zili's background, seemed somewhat plausible. Whether or not it could deceive them would depend on his luck.
But even if Xie Qiansi had the wildest imagination, he wouldn't be able to think of anything; at most, he would later be surprised and wonder 'how did Ren Suo just happen to encounter Zhao Zili'.
Did Ren Suo have any leverage? No.
