I Bound a Cultivation System in My First Year of College, Then Handed It Over to the Nation

[An Entire Nation Ascends to Immortality + Cultivation + Spies + Campus Beauty + National Support] I had just started my freshman year when the System insisted I join the Demonic Sect, the Joyful Union Sect. It even told me to forge a bond with a celestial maiden glowing with golden light. The rewards included immortal spells, talismans, elixirs, and all kinds of cultivation techniques. So I turned around and handed myself over to the country! The nation helps me win over the goddess! From then on, while other countries focused on developing technology, Dragonland used cultivation to overtake them by taking a shortcut. Other countries are struggling to build humanoid flying machines. Ever heard of flying on a sword? People in other countries each carry five grenades. Dragonland's soldiers carry talismans by the sackful. Other countries are developing interceptor missiles. Dragonland simply activates a grand formation to protect the nation, complete with a Tribulation of Immortal-Slaying Swords: billions of blades rain down and shatter mountains and rivers. The Countries Can Stick to Their Tech, I'll Cultivate Golden Immortals for Dragonland
