In the cultivation system of Sea Blue Star, where Spiritual Energy is in short supply and practice methods are outdated, magic spells are extremely rare. Yano Luo was very lucky to have obtained one.
Especially since this spell could greatly enhance the combat power of Ancient Martial Artists; with an entry-level Grandmaster Realm capability, one could slay mid-stage Grandmasters.
The spell that Sun Lihua was holding was the very foundation of Yano Luo's vendetta visit— the Thunder Mastery Technique.
He hid it well before leaping out of the deep pit.
As the behind-the-scenes boss of the City North Qingyun Gang in Zhonghai City, he knew better than to publicize this incident. If word got out that he had acquired the Thunder Mastery Technique, it might shake the entire Ancient Martial World, possibly bringing out those ancient martial families and powerful sect forces. A confrontation could lead to murder and robbery.
