Whoa, whoa, whoa!

Available now!

Did not expect it!

The competition is so fierce that there are better recommendations, and the results are close, so it's on the shelves.

Thank you all for your support all the time!

The new book period is neither long nor short.

In particular, I would like to thank the book friends who voted and rewarded me every day.

Please subscribe!

In addition to feelings, writing a book also requires food. Science and technology books are different from fantasy cities. There are almost no third-party channel royalties, and they all rely on subscriptions.

Therefore, your subscriptions are very valuable, I beg you not to watch pirated copies!

I hope that the first order will be 2000, although I feel that it may not be reached, but what if there is?

If there are 2000 first subscriptions, I will guarantee 3 updates every day from now on, and I will add one more chapter for each additional 100 subscriptions.

Hope you guys make my dream come true.

Finally, please subscribe, please subscribe, please subscribe!

Love you guys!
