Whose System Is Windows?

I've traveled through time. It looks like a recruitment scene during the Spring and Autumn Period. Wait, why is the recruiting officer asking them one by one what level of Qi refining they have? What about the system? Shouldn't there be a system for time travel? Good news, yes. Bad news, other people's systems issue cultivation bases and magic weapons, but my system only reports errors. And I don't even have login rights. Shen Xu looked at the window that just popped up in front of him and fell into deep thought. No. Whose system is Windows?
