At the start of the Nesser Dynasty, Garcia, who had just advanced to the Archmage realm, went to the capital city of the Nesser Dynasty, but he ended up clashing with a Pure-blooded Elf, and soon after he left the capital city, he ended up being chased by three 7th Rank Archmages. 

But Garcia let everyone experience the terror of a Master of Mantras, as a 1st Rank Archmage, he sadistically killed three 7th Rank Archmages.

It was later revealed that Garcia had received the inheritance of a first-rate Master of Mantras and possessed countless mantras. Just the Silent Curse could make the three 7th Rank Archmages unable to chant a single character.

As he used more and more High Tier Mantras, he achieved the feat of killing three 7th Rank Archmage on his own.

When Garcia, who hardly had any attacking Mantra, reached the 9th Rank, there was almost no one under the Heaven Rank willing to face those High Tier Mantras...
