At that time, "Lightpulsar Dragon" was sent from the field to the Graveyard, and activated its effect to Special Summon a Level 5 or higher DARK Dragon-Type monster, and "Raigeki Break" was chained targeting "Spell Canceller". In this scenario, while the effect of "Zombie World" will be applied once again, treating all monsters in the Graveyard as Zombie-Type monsters, can the effect of "Lightpulsar Dragon" still Special Summon the targeted monster?
