Master Wen, like Erlang God, has three eyes, and the middle eye can distinguish faithfulness and treachery and see through people's hearts. He is an intercepting disciple, a disciple of the Virgin Dolly in Biyou Palace. Most of his disciples were trained by animals. While da ji was possessed by a fox, Wen Taishi actually felt the need of da ji, but because of her identity, she could not directly call her a monster, otherwise it would be easy to offend her classmates. And at that time, he didn't have much energy to take care of da ji's affairs, because Shang Zhouwang was obsessed with beauty and didn't ask about the failure of state affairs, and Wen Taishi was suppressed by internal rebellion in Shang Dynasty to seek the Western Expedition. At this time, the Shang dynasty was already a soldier at home and abroad. So a surname Wen has no time to take care of da ji's funeral. He just kept trying to persuade Shang Zhouwang, but he didn't succeed.
Moreover, da ji was sent by Nu Wa Empress to deliberately confuse Zhou Wang. If Dan Tai Wen resolutely expels the goblins, it will be fate. Moreover, da ji's troublesome harem is not under the jurisdiction of Master Wen. Shang Zhouwang was obsessed with the beauty, fatuity and cruelty of da ji. Although he was angry, he still believed that Shang Zhouwang could handle the harem affairs well. And the king's harem, detained also inconvenience to intervene, so deal with da ji have to be executed by Shang Zhouwang. Although he was a loyal minister, he witnessed that Bigan, who wanted to get rid of da ji, was poached. He did it to save himself. So he can only earnestly persuade Shang Zhouwang, in addition, there is nothing he can do.
In a word, Master Wen has never practiced distinguishing da ji from being possessed by a fox, but he can't judge that da ji is a demon just by the evil spirits he has identified. Moreover, da ji is protected by Shang Zhouwang, so it is difficult for him to get rid of this disaster, otherwise it will hurt himself. So for the sake of the overall situation, he can't get rid of his demons. In a word, Master Wen knows that da ji is a monster, but he can't see that she is possessed by a fox.
