Just became the disciple with the highest seniority, but the Age of the Dark Mist descended, and the sect plummeted into a land plagued with raging demons.

Shen Changge who had already written his suicide note suddenly awakened to a Check-in System.

[Check-in at Sword Lord Statue, Success, acquired: Empyrean Sword Manual]

[Check-in at Training Ground, Success, acquired: Cultivation Base*50 years]

[Check-in at Sword Clout Mountain, Success, acquired: Sword Clout of Destruction*1s]

…

In the Age of the Dark Mist, demons were rampant, and an impenetrable mist veiled the empyrean. By vanquishing demons, the mist could be dispelled, and new check-in locations could be unlocked. By doing so clandestinely, Shen Changge became a Sword Saint.

When a demon broke into the Empyrean Sword Sect, everyone in the sect was powerless. People were in despair, until they met that young man in white who had just checked in at the Empyrean Peak. The young man’s eyes were ablaze.

“Submit, demon.”

There’s SIS in great Britain, CIA in the US. In Huaxia, there’s Dragon Division, known as the mysterious power of the East.

When a soldier that originally failed to be selected to join, appeared on the Dragon Division’s list again, no one noticed, that this inconspicuous and humble looking guy was actually the Dragon King of the division, the one that’s most difficult to deal with.

He was a man, whose appearance gave every one existential crisis, including a fly that was consecutively caught by him with a pair of chopsticks.

Of course, this story is hilarious as well.
[Shen Yao laughed. “You think I would help you? For what reason?”

Xu Cheng sighed. “Shen Yao, to be honest, you are really pretty.”

“Humph.” Shen Yao snorted coldly, “Can you elaborate on that for me?”

“I don’t know how to get into details, but I can only say that when I accidentally tore your skirt today, I got a boner.” ]
