It's definitely not "The Hidden Dragon in the Mirror", the lyrics don't even match. It should be "Yu Long Wushuang" by Xu Liang, LZ will know the lyrics:

A long time ago

A girl is by my side

Close to me On my shoulders

Our love is so direct

Suddenly overnight

My world is in flames

Wearing superimposed swords

People call me General Risk

I look left and right and I am unstoppable.

But I am a little sad. .

You are a hero

A lonely empty city with a lifetime of heartache

Who will miss me

But being alone is not the loneliest thing

Your face is deep in the back of my head, how can I not feel heartache

The more I think about it, the more intense it becomes.

Fangtian Huaji is in my chest. Who dares to laugh at me

After a long, long time

When it comes to the sunrise, nothing will be left behind

I will be waiting for you

Also Being quietly taken away by time

I tried my best to kill the enemy generals with a sword but did not kill them

How could it be a familiar look? . .

You are a hero

A lonely empty city with a lifetime of heartache

Who will miss me

But being alone is not the loneliest thing

Your face is deep in the back of my head, how can I not feel heartache

The more I think about it, the more intense it becomes.

Fangtian Huaji is in my chest. Who dares to laugh at me

You are a hero

A lonely empty city with a lifetime of heartache

Who will miss me

But be alone The soul is not the loneliest

Your face

How can I not feel heartache in the back of my head

The more I think about it, the more intense it becomes

Fang Who dares to laugh at me if I have a halberd in my chest?
