Recently, there are a lot of things in the ancient knife unit and at home, so there is no way to update it stably, but the ancient knife is still writing in my spare time, please rest assured, the story is not a eunuch.

This story is only one-tenth, and there is still a long way to go, so I hope you can endure it and wait for more.

I would also like to thank my book friends who have always supported me.

"Imperial Black Technology" about the update of the question is in hand, please wait a moment,

Once the content is updated, please refresh the page again to get the latest updates!
