When Xu Feng thought that there was a lurking sentient being overseeing their actions, he wasn't being paranoid.
After all, the symbols that involved the usage of Mana-Bane Thistle and Veilroot Essence essentially eliminated all those attempting to solve the puzzle without any prior knowledge or experience in Herbology.
Since Xu Feng had been exposed to both and was familiar with such herbs. Then naturally, its effect couldn't affect him in contrast to Carmen and Crimson Heart.
And this was what made Xu Feng suspicious.
Unless the puzzle somehow knew there was one experienced Herbalist here, then such a puzzle wouldn't have appeared as an obstacle to them.
As harsh and despicable as the Divine World was, it had always been fair to its players, ensuring that every obstacle was doable as long as the players gave their utmost effort.
