I hold the shield of thought I

I hold a shield "Shield of Thought I" A shield (?) found by the Adventurer's Guild in the ruins of the Demon Swordsmith's Workshop. The design is called an ancient shield by future people, and it is a barrier that confuses modern people. Some scholars from the Magic Sword Journal believe that if the sword is held in a different way, it will become a weapon, sparking controversy. It is speculated that there seems to be a lack of some kind of starting energy. Some people think that the source of this energy is related to the heart. But how to activate this "mental defense" is still a controversial issue in the academic community. Sometimes the more you explain things about thoughts to others, the less they will be understood. There are multiple photos for reference The full shield is about 62 cm long and 36 cm wide Shield material: 304 Stainless Steel https://youtube.com/shorts/0ef2UImby6I Shield holder: You Chenyuan (YCY)
