Powerful Google

This website is just published days ago, and when I search site:bai.uno on google, I found the searching result is like the below:

I insert the robots.txt to disallow all the search engines to index my site.

User-agent: *
Disallow: /
Disallow: /404.html
Disallow: /404

Sitemap: /sitemap.xml

So there is no descriptions on the results.

And I did not public the link in other sites, except my github’s Readme.

So what I want to say is google’s technology is really powerful.
