You give Bai Shuang her father's belongings.

Now I wonder if we can find the door this keycard opens...

Show the Tianshi apparatus

Old Bai... Were they talking about Dad?

What were they celebrating on the day of the disaster? I don't think I'll ever find out.

I remember ... when I was a little girl, I really wanted to play with the Tianshi apparatus, but Dad wouldn't let me.

There was this time when he rushed out and left it on the table. I tried climbing and grabbing it, but accidentally dropped it onto the floor.

I thought I broke it and kept crying till Dad came home. And that was how this Tianshi apparatus got a scratch. It's right here...

So these are what he left behind... Dad, I've earned my own Tianshi apparatus... Can you see it?

Shuang... You're like the first Tianshi disciple of the yard. Uncle Bai is definitely proud of you.

Thank you... I really appreciate this...

Lifeng, did you find your parents' belongings?

Xingzhi... That's Dad's name! He was here before!

Thank you, Shuang! I spent ages poking around and didn't find anything! This is like ... my first useful lead!

And, yeah ... please don't get too sad.

I ... I'm not.

Really?! I'll go look for them now!

Yeah. Ah Sheng just told he's coming over with Xiao Ran. I think they're headed to the Arsenal of the Bureau of Swordmancers.

Mom and Dad's stuff...? I tried, but I couldn't find any leads. I don't even know where they were at that time...

I actually found this. I hope you find it useful.
