What was it that made him lose his mind like this?

Lan Wangji was asking himself after the vigorous session. He was already up and took a shower and now he was watching Wei Wuxian sleep soundly on the bed with his brows furrowed, as if thinking of serious matters, and lost in his train of thoughts.

How come the Phoenix Blood amulet did not hurt him?

The Phoenix Blood amulet was a condensed version of the real phoenix blood, which contained more than ten drops of highly poisonous dark phoenix blood. 

For an ordinary human, being in a close vicinity of the amulet would give them nausea, headache, vomiting like radiation poisoning. Closer than that would give them cancer and worse than death condition when it was worn on the person. 

This was an entirely different league from the ordinary phoenix blood which had the rumored capability to resurrect anyone by trial by fire.

But for the mythical beasts, it had a very high value and it was very sought after. It had the capability to heal wounds, protect the owner, and resurrect the dead, if you could form a pact with it. Beasts would kill their own flesh and blood for the ownership of the amulet.

And it was refined from Xiao Hei's parents' blood. 

It was supposed to be a protection and mostly a sentimental memento for Xiao Hei, and he just easily gave that to Wei Wuxian for some unknown reason.

And the strangest thing was, Wei Wuxian didn't seem to be affected, although he was supposed to be human.

Supposed to be human.

What if…

He'd probably need to go through a lot of ancient records about what exactly happened behind the night of Xiao Hei's family massacre. The conspiracy, the plot, the betrayal, all that happened a hundred years ago. 

That was the only thing that he ever regretted in his life, not being able to save them, the last blood of the royal phoenix celestial beasts.

Now, seeing Wei Wuxian; a mirror image of Xiao Hei; and the ones behind him, he started to get a clear idea about what exactly happened.

Fuck he really needed to talk to Xichen, there's no way out of this now. He dreaded the thought of going back to the mansion and seeing Xichen and hearing his unending nagging about everything under the sun.

He groaned inwardly.

"If you're staring at me like that, soon enough you'll bore a hole in my head and I'm not gonna be able to be much of a use for you."

Lan Wangji was so deep in his thoughts that he didn't see Wei Wuxian had already woken up.

"Ugh, you're such a beast. I got marks everywhere, and I'm really really sore. Can't you at least restrain yourself next time?"

Good question. 

Could he?

"Anyway, I really need to get back home." Wei Wuxian started to stand up and gather his clothes. "My roommate will be worried if I don't. By the way, you ripped my pants."

"Right. I guess that million dollar cheque will cover that."

Wei Wuxian paused in the middle of inspecting his pants, the he looked at Lan Wangji with an obvious contempt in his eyes.

"You know what? You really are an asshole, Lan Zhan. You insulted people then threw money on them, for what? Buy their silence? Cover your insolent behaviour?" He put on the pants and the shirt in haste. "Could you at least be a decent human for once? Oh wait, never mind, you're not a human anyway, you're a beast. It suits you." Wei Wuxian suddenly flared with anger, hearing those money words from Lan Wangji. He put on the rest of his clothes and went out of the door in three minutes flat. But before he went out, he turned around and spoke to Lan Wangji in a cold voice.

"By the way, I never cashed your cheque. I was planning to rip it and throw it on your face. Just you wait." He then proceeded to slam the door loud enough to wake anyone asleep.

Lan Wangji waited a beat before he threw himself on the couch, hands rubbing his face in frustration.

Why was it that everytime they met, it always ended up with him putting his own foot in his mouth?

He sighed.

Guess it didn't matter if you had lived for a couple of decades or millenium, human relationship was the hardest to navigate. In the olden days he preferred to enslave humans or stayed away as far as possible from them. They were just like this annoying pests who kept coming even though he either killed or avoided them like a plague.

He wondered why he invested his time for this… strangely intriguing human. 

Who made him weak.

Literally and figuratively.
