Impossible!
Soon, Song Jiangxing ruled out this guess. There was no other reason. Zhu Wuyang was too weak.
He was just a cultivator who had just advanced to the Nascent Soul stage. Even if he had the help of talismans and spirit weapons for breaking formations, it was impossible for him to sneak in here silently and poison nearly a million female cultivators with the Drunken Night Incense.
Therefore, the poisoning incident was definitely not Zhu Wuwan's doing. It should be done by some Soul Formation Realm cultivators who were good at poisoning.
According to the information they had received, although Zhu Wuan was a newly promoted Successive Crown Prince and the mountain range he was in wasn't very good, he was very good at recruiting people. In just a year or so, he had managed to establish a force that was not inferior to some of the older Successive Crown Princes. He had many capable people under him.
