The Devil's Fiance Is The Alpha's Mate
[Warning: This is a BL novel, and mature scenes ahead!] Chen Ming, an ordinary twenty-five-year-old office worker, falls into a pit one day right on his face. The next moment he opens his eyes to a little chick flapping its little wings on his face. "Yo, I'm your system, Chick, and I'm a reverse harem system." The chick flapped his wings as if doing a happy dance. "Congratulations user, since you have fallen into the pit, consider yourself lucky because now, you'll be granted a wonderful opportunity to be done by two men!" "Wait, I'm straight," replied Chen Ming straightforwardly as his face remained cold and composed. "So what?" The chick waved his non-existent hair back as he said, "You don't want to be done by two men? I can offer you more if you want." "What if I want to refuse?" "You'll die." "....." The boring life of Chen Ming suddenly changed, especially because he wasn't fucking bent in the first place!
A War!
Chen Ming continued to follow the man once again. He didn't know what he was about to gain from this, but at the very least, after a few more days, he finally realized why Liu Song was so strange at every turn. Why the man seemed to be extremely human and another second a person with extreme vigor.
One simple word: Liu Song probably had multiple personality disorder.
Of course, Chen Ming couldn't be sure because he didn't get to interact with the Emperor other than a handful of times, which wasn't enough really.
Thus, he decided to continue to follow the man at the same time, he started learning the martial arts guidebook that the system gave him along with the weapons. Although this guidebook seemed ordinary, there was nothing around that. With every turn, he was able to experience those moves just like that without even having to practice it.
