At the Beginning, the School Beauty Knocks on the Door, and Awakens to Follow the Rules

[Sweet article + Double Strong + School Beauty + Rebirth + Time Travel + SSS Sword Fairy Heroine + Spoken Words + Send Wife at the Start + System + Two-way Guard + Kill Monsters and Upgrade + Climb the Tower] My name is Lin Wan'er. In my last life, I awakened the SSS-level talent [Frost Moon Sword Immortal]. My swordsmanship is the best in the world. I broke through the 99th floor of the God Tower alone and killed four Demon Abyss Lords. I was only one step away from becoming a god. But I mistakenly believed in the jackal. When I attacked the divine realm, I was plotted by the King of Demonic Abyss and the traitor of the divine tower. The seven ninth-level peaks surrounded and intercepted me. In times of crisis, Jiang Bai, who only had SS level [100 times damage], used his weak seventh-level body to overwhelm a strong enemy, died with his bones broken, and used his life to fight for a glimmer of hope for me. I held his cold body and walked alone in the ice field for seven days, and finally died from exhaustion. Back on the eve of my awakening at the age of eighteen, I swear—— I will deal with the enemies who killed me one by one; I will never let the young man who sacrificed his life to protect me die alone again. In this life, I will hold the frosty moon sword in my hand, protect Jiang Bai and reach the top, crush the demon abyss, and reach the top of the God-conferring Tower! ... My name is Jiang Bai, a time traveler! I traveled to a world of high martial arts, where there are divine towers, demonic abyss, and the awakening of all people. The good news is that I have awakened the [Causal God System] - by consuming the causal value, I can speak Dharma Sui. The more consumed, the stronger the power. The bad news is that there is only 10 causality points at the beginning, so even soaking the instant noodles in advance requires careful planning. The worse news is that there is a girl named Lin Wan'er living next door. For some reason, she squats at the door of my house every day, with complicated eyes, and protects me in every possible way. She always stands in front of me, and she opens and talks "Brother Jiang Bai."
