Gravekeeper of the Star Sea

In the Star Calendar era, high school student Lin Yi unexpectedly received an email from the Gregorian era. It was filled with Chinese characters he couldn’t recognize, and led him into the world of supernatural arts. From then on, he stepped onto battlefields teeming with supernatural-art war gods and mecha warships. Only later did he discover that the starry expanse where everyone fought so fiercely was actually a dark graveyard. The powers he wielded were the legacies left behind by those celestial bodies.
