Before this, Han Yi had already been informed of the things he should and shouldn't do when the foreign swordsmen went up Sword Mountain.
The things he should do were simple: go up Sword Mountain, choose a place, perform his swordsmanship, sword moves, and sword secrets, and this would stimulate the mountain's response, which would then guide the formation of Sword Marks on the mountain.
What he shouldn't do was use skills other than sword-based ones. Of course, this did not include investigative magic skills like Qi Observation Skill. Sword Mountain was open to swordsmen from all over the world and did not fear being spied upon.
However, if he were to use other skills, such as suddenly using the Spirit Void Finger or the Spirit Flame Skill, Sword Mountain would consider it an attack by a cultivator, and would counterattack automatically. Even though the power would only be ten percent, it would be enough to give a Nascent Soul expert a hard time.
