#edit: I can't believe I completely ignored the vibe of the song and just went “[pointing] Lu Guang?!” just because it started after that

[butterfirefly]

Hang on. It seems like Mastermind isn't Lu Guang's song like I thought it was but Liu Xiao's. Lyrics below with the Chinese parts translated via Google.

Time is a hypocritical construct

Righteously it wipes out all of us

But I keep rising back from the dust

Again and again again and again

无数碎片 [countless fragments]

不停缠绕相连 [Continuously entwined and connected]

The shadows they whisper in your head

I let them linger and you will like it

You're tied on my strings like a puppet

Before you even notice

I made a deal with the demons

I crave the feel of true desire

There's nothing real 终究走向黑暗 [Eventually heading towards darkness]

Listening all your desperation sounding like a song

Destiny is just my game but is all you counting on right now

Joining the game

Killing spree I'm enjoying the game

So get ready I'm here

Get ready for it for it

Again and again again and again

Take my hand let's set this world on fire

Light it up for the show

Pain will get to you when the night arrives

Like the hunter when a prey lies

It's just how the world's like

Dadadada dadadada

Got nothing holding me back

Dadadada dadadada

Mastermind stays in the dark

Let my flame be your redemption

If you ever get helpless

Just take it in and we'll have some fun

在雷鸣之间我不计代价 [Between the thunder I don't care about the cost]

承受无限电压太蛊惑的力量 [The power to withstand infinite voltage is too bewitching]

在每个时间都呈现我推演结局 [Show me the ending of my deduction every time]

没人能改变或阻挡 [No one can change or stop]

You're down on your knees 'cause u can feel the pressure when I'm taking over

Ain't no too hard to see so u better believe

我就是唯一信仰 [I am the only faith]

一切熟悉的全坍塌 [Everything familiar collapsed]

棋盘上未知的玩家 [Unknown player on the board]

Joining the game

Killing spree I'm enjoying the game

So get ready I'm already here

Can't you see it's a checkmate uh

Take my hand let's set this world on fire

Light it up for the show

Pain will get to you when the night arrives

Like the hunter when a prey lies

It's just how the world's like

Dadadada dadadada

Got nothing holding me back

Dadadada dadadada

Mastermind stays in the dark

Let my flame be your redemption

If you ever get helpless

Just take it in and we'll have some fun
