Ah guys the True Longinus doesn't belong to Issei, it is still owned by Cao Cao as to why the Truth Idea didn't work is because the God's will chosen Issei's dream thats all. As it's ability to destroy the world, the author never stated that, it is just that the True Longinus is the first Longinus to be made as to why it is called the strongest Longinus is because it is the first and only Sacred Gear/Longinus to successfully kill a God. None of the past possessors of the 12 other Longinus has killed a God before.
