Zhang Jiangbei's suggestion was indeed comprehensive, but regretfully, it was of little use.
Han Zheng knew that a covert investigation was certainly the safer approach, but the problem was they didn't have that much time.
This place was Taishan Prefecture, and they were Xuanjia Guards of the Kui Character Camp, unable to stay here long-term.
Moreover, if Tang Jue and his team completed their mission first, it would make Han Zheng and his team appear to be dallying uselessly.
"An undercover investigation definitely won't work, we don't have the energy, nor the time.
Rather than waiting for the opponent to slip up, it's more reliable to investigate personally.
Zhang brother, please write me a visiting card. I need to go to Asking Sword Manor and see for myself."
With Han Zheng so persistent, Zhang Jiangbei did not offer much persuasion and immediately wrote a visiting card.
However, Ye Liuyun frowned as he looked at the nearly cautious and humble tone of the visiting card.
