[Two powerful leads + both pure-hearted + quasi-infinite-tower adventure + supernatural horror + devoted 1v1 romance]
As a competent undercover agent, Sheng Lian had endured almost every hardship imaginable, both the ones he should have faced and the ones he shouldn't. He tried to die but failed, and ended up as an "experimental subject" instead.
With the intervention of three "forces," two acting openly and one in secret, he spent a brief period recovering through missions themed around "transmigrating into a book."
Returning to reality, still wanting more, he was greeted not only by a strange pair of brothers, but also by a world of the uncanny that couldn't wait to pull him in.
Sheng Lian once had a System, and it gave him "experiments";
he once had a little red umbrella, which he gave to Qi Ji;
he once had a library, which became his castle...
He sank deeper and deeper, almost ready to give up fighting, when his light appeared once more... His memories slowly began to return.
