Stranger's Handbook - Chapter 28: Journey to the Imperial Capital

Dimensional Rifts permeate throughout the Chaotic Universe, bringing with them immense dangers… as well as innumerable treasures.

In a small Realm, a destitute boy awakens the Idle Gaming System.

Countless Dimensional Rifts later, he lazily raises his head to realize… he is invincible!

The clock struck midnight when Ruelle heard the echo of footsteps. She tensed, the fine hairs on the back of her neck standing on end in the cool night air.“You shouldn't be here,” Ruelle whispered, her voice a breathless murmur. The silhouette finally came to stand under the moonlight, his dark red eyes watching her and his inky black hair ruffling.“Shouldn't I?” His voice was a dark caress, and she stood there captivated by the danger he exuded like perfume.“I haven’t seen you for the last two days,” his tone low. His hand reached out, fingers brushing against the silk of her nightgown, tracing the trembling outline of her collarbone. “Tell me, were you avoiding me, or perhaps... entertaining other offers?”Ruelle’s heart raced, her breaths shallow. She declared, “I don't belong to anyone.”“A bold claim,“ he murmured, his breath a tantalising chill against her skin as he leaned in. ”Yet here you are, pulse racing, your body tensed as if in anticipation of my touch.”His fingers gripped her chin, tilting her face towards his. The moonlight caught his eyes, revealing a glint of predatory intent. “Or must I remind you whose touch you truly crave?”

When Ren Sheng is being hunted, in order to not fall into the hands of his enemies he decides to jump into the crack of space and time. Unexpectedly, he crossed into the future and was forced to substitute as a bride while he was still in a coma.

When he wakes up, he actually has a husband… Ren Sheng is extremely satisfied.

Such a delicious nourishment, this is his first time seeing it! Really want to root up ah ah ah!

As a result Lord Marshal, who was sick in bed, had a “little wife” who has been touching him all day and drooling over him.

Kyle woke up in a land of fantasy and magitech. The usual 'I died and woke up' bullshit, skip all that.

Except he used to be a crime lord, and society here is missing that extra kick.
