A Divine Dragon Descends? That's My Summoned Spirit

【Spiritual qi revival + beast taming + urban supernatural powers + one heroine + progressive power growth + divine sequences + plot-driven + no System, no rebirth + unconventional, invincible protagonist】 Thirty years ago, humanity harnessed the power of demonic spirits to revolutionize technology and built a city in the sky. Eighteen years ago, Qin Yan’s birth sealed away the vast majority of the demonic spirits, ushering Blue Star into an era of peace. Now, the sealed demonic spirits are suddenly reviving, returning after years of silence. On a crimson, rain-soaked night, Qin Yan awakened a lightning-type spiritual meridian and summoned the strongest demonic spirit: the Yinglong of the Classic of Mountains and Seas! What? You’re saying I can only use it on a trial basis after I just summoned it? No problem. His spiritual power had peaked at birth, after all, so defeating monsters and leveling up was a piece of cake. First-tier spiritual power, second-tier spiritual power, third-tier spiritual power… He leveled up at an absurd pace, a true genius! He killed every demon he encountered and slew every god, each strike hitting home! Don’t waste the gods and demons you’ve slain. Coat them in flour and toss them into Qin Yan’s world of consciousness until they’re golden brown, no, wait, sign a contract with them! Xingtian, Xiangliu, Gonggong, Luwu… All the divine beasts of the Classic of Mountains and Seas could be summoned. Even the seventy-two demonic pillars of Solomon lined up to bow and pledge their allegiance. “If there are no gods or Buddhas in this world, then I will save all living beings!”
