Chapter 557: Chapter 505: International Medical Department

When Yang Ping woke up, Xiao Su was already busy in the kitchen preparing breakfast.

Their experiment last night was quite exhausting, as it was ultimately an exploration of the origin of humanity.

It was the first time for both of them, so they couldn't help but be unfamiliar. They had to carefully explore and progress gradually.

On the bedside table, the clothes Yang Ping was to change into were neatly stacked.

In the bathroom, a toothbrush lay across a cup with toothpaste already squeezed onto it; a basin was set, with a washcloth folded in the center.

The mirror was covered in a layer of water vapor, and something was drawn on it using the water vapor.

Upon closer inspection, Yang Ping saw it was two heart-shaped figures holding hands.

"Breakfast is ready---"

Xiao Su appeared at the bathroom door, looking stunning even in her pajamas, causing Yang Ping to pause.

"Why are you staring at me? Breakfast is ready!" Xiao Su blushed, looking shy.
