If you want to lure the snake out of its hole, then you must choose bait that your enemy simply cannot resist.
Within the entirety of the Divine Wood Sect, aside from Chen Mobai and other cultivators who have already achieved Core Formation, the one who makes the enemies most wary is undoubtedly Yin Qingmei with her Heavenly Spiritual Root.

If there was an opportunity to eliminate her in advance, they would undoubtedly take immediate action to kill her.
And Chen Mobai wasn't spreading false information; Yin Qingmei indeed needed to go to Rainbow Country to adjust her Fire Vein and plant trees to treat the sand. Zhuo Ming had also visited Qingdai Mountain several times to discuss this matter with her.
Once Liu Wenbo received guidance from Chen Mobai, he immediately had an epiphany and left Xiao Nanshan to arrange this matter.
