Clarification - if someone is a Martial Grandmaster and becomes a Martial Expert their lifespan increases by 100 years and when they reach Martial Lord it increases another 150 years so to find out their new life span it would be: Original lifespan+100 (from their breakthrough to Martial expert)+150 (from their breakthrough to Martial Lord) NOT Original lifespan+150. Original lifespan refers to their lifespan if they had not reached the level required for their lifespan to be extended.
