National Destiny: He created his own "Covering the Sky" technique and started by forcefull

[The National Fortune System descends into reality, creating a self-developed cultivation system to withstand the monsters, anomalies, and all other terrors that will descend in seven days.] Lu Ran thought, "I know this like the back of my hand!" After being a bookworm for so long, this is the time to step in! However, the prerequisite for participating is that Lu Ran kisses the school beauty, which he's more than happy to do! As the saying goes, "If I don't go to hell, who will?" During the creation phase, Lu Ran uses the Heaven-Covering Technique to stimulate the body's own potential and open five great secret realms! Let the entire nation of Dragon Kingdom know the power of this Heaven-Covering Technique! The five great secret realms are: the Immortal Platform Realm, the Quasi-Emperor Realm, the Great Emperor Realm, and the ethereal Mortal Immortal Realm! ...Seven days later, spiritual energy recovers, and monsters and anomalies descend. The various nations look on with dismay at the cultivation systems created by their contestants! Eagle Nation: "Wait, shouldn't mages be the strongest? Why is this Dragon Nation's Heaven-Covering Technique ridiculously powerful?!" Sakura Nation: "Ninjutsu is clearly invincible, so why aren't they afraid of demonic beasts and monsters?!" Korean Nation: "Contracted mecha girls don't sound as impressive as this Great Emperor!" Bear Nation: "Arcane magic can't compare to the Heaven-Covering Technique, so why?!"
