Li Yan, an ordinary college student, has a prehistoric code that even he doesn't know running through his blood. When the spiritual energy revived, the phantoms of mountains and seas and strange beasts appeared in the sky around the world, and he was involved in a huge chess game that spanned eternity. The candle dragon pattern that appears on his left eye is not only the authority to command the ancient "ancient spirits", but also the shackles of sacrifice set by the ancient gods and demons for him and from which he cannot break free.
From the Blood Altar in Kunlun Ruins to the City of All Spirits at the Gate of Guixu, Li Yan worked side by side with Su Yao, who was burdened with the fate of the nine-tailed fox, and Ao Hai, a descendant of the dragon tribe, to fight against the greedy Soul Seeking Society, the mysterious Penglai Capital and the conservative remnants of Heaven. He gradually discovered that the power of the candle dragon in his body was the only key to unlocking the ruins, and deep in the ruins, the ultimate truth and legacy of the previous civilization's fight against the "world swallowers" outside the starry sky were sealed.
When the shadow of the "World Devourer" once again enveloped the starry sky, Li Yan faced the ultimate choice: follow his fate and use his body and Tao to become a ruthless guardian deity; or use the heart of a mortal to harness the power of gods and embark on an unprecedented path? He weaved together the power of the candle dragon, modern technology, global awakeners and the will of ancient spirits to create an active defense network called "Mountains and Seas" that covers the world.
This is a war with the earth as the chessboard and civilization as the bet. In the end, he understood that the real "mountains and seas" are not the divine power to move mountains and reclaim seas, but the immortal will of hundreds of millions of ordinary lives to protect "tomorrow". When divinity fades and legends settle into history, the oath of guardianship will be replaced by new fire.
