I just thought of a better title, but unfortunately, I can't change it: After the Immortals' Destruction: Rebuilding, a Plan for Gods and Humans to Coexist
(Modern urban fantasy + multiple love interests, no female lead + reborn + a little comedy. The blurb doesn't do it justice, so read the novel!)
A destined wielder forges the vault of heaven; a tempered heart and resolute will shape the world.
Shen Ye is unexpectedly reborn, only to discover that this is not merely the ordinary world of fifteen years ago, but a world where the Dao has vanished in the wake of the Day of Annihilation.
With the Heavenly Dao's constraints gone, the immortals and demons who were lucky enough to survive the Day of Annihilation interfere in mortal affairs. The human world has become filthy and corrupt, and its people suffer terribly.
By chance, Shen Ye obtains the most powerful technique of the Ten Great Immortal Sects, the Supreme Art. Wielding his Frost Sword, he slays demons and vanquishes monsters, obtains the Sea Emperor's Pearl, and embarks on a journey to fight the uncanny and rebuild order.
At first glance, it seems that the author has life experience, a new and experienced author, the plot is twists and turns, and the language is smooth, but the writing is a bit slow.
It's okay, it's a bit logical, not mindless. But it would be better if the protagonist was more awesome and ruthless
