First of all, I apologize to my friends who have interfered with reading. The specific reasons are as follows, because the original title of this book is "I am antivirus" and then three chapters have been updated, namely "Dark Prologue", "Demonic Spirit", and "Plant Gene Fragments". But later the book was renamed "Endless Pursuit", so there were some changes in the plot, so I deleted the above three chapters, and the official plot started with the two chapters of "Night Watch" and "Mutation". However, some readers reported that the first three chapters still exist in the mobile version of the starting point, which really makes me feel helpless, because I did delete them in the computer version. It is hereby stated now. Thank you all for your support.
