Just After Our Wedding, My Childhood Sweetheart Was Forced to Become Empress

System + sign-in + empress + one female lead + one female lead + one female lead (repeating this three times because it's important)

Lin Tian's soul transmigrates to the Hongmeng Continent. His parents died when he was young, and he and his childhood sweetheart, Luo Wushuang, share a deep bond. The two have always depended on each other.

They've only just gotten married, and haven't even had a chance to hug, when Wei Yan, the chief eunuch of the Eastern Depot, arrives.

It turns out Luo Wushuang is the long-lost Princess Yuli.

Wei Yan forcibly takes Luo Wushuang away, intending to make her the empress of the Tianyuan Dynasty.

At last, the useless System awakens.

The System lets him sign in to obtain all kinds of abilities and items, even lifespan and cultivation.

See how Lin Tian becomes an invincible powerhouse step by step, crushes all opposition, wins the beauty's heart, and helps the empress build an unparalleled dynasty.
