"Congratulations, host, for killing the three-star villain Le Rushen and acquiring the Martial Arts Inheritance: "Heavenly Mechanism Divination Skill" (three stars) and "Boundless Dreams" (pitfall) (three stars)."
"The Heavenly Mechanism Divination Skill" uses the Dao of calculation to find the weaknesses in an opponent's Martial Arts, thus breaking through them. It's referred to as Martial Arts, but in reality, it is an application of Yi Skill.
Le Rushen's inheritance from the Heavenly Mechanic Sect was far inferior to the Yin Yang Technique of the Yin Yang Family, but his foundational knowledge in Yi Skill could save Qing Yu a great deal of time, significantly advancing his "Astrology Law" and "Heavenly Son's Qi Observation Skill."
The other technique marked as a "pitfall," "Boundless Dreams," isn't entirely a trap. After all, Le Rushen was intelligent enough not to cultivate something that was obviously deadly.
