"The Celestial Curtain is a realm one can only reach by cultivating hidden weapons to their absolute limit!"
"A person who specializes in hidden weapons, upon reaching a certain level of power, can control hundreds of them at once. They are inescapable, and with a mere flick of the wrist, one can kill without a trace!"
"Cultivating hidden weapons to the Peak Realm allows one to control over a thousand at once! A single person's attack is like an army of thousands firing arrows in unison! Most importantly, you never know from which direction these weapons will strike, making them impossible to defend against!"
"For one person to control over a thousand hidden weapons simultaneously is already an ultimate achievement, because a person's Spiritual Power has its limits."
"But the Celestial Curtain... goes beyond that ultimate achievement!"
