I didn't enjoy the chapter. I have seen a lot of "Vampire" type of books and this one didn't reach the level of a "Good" unfortunately. and if you are reading my comment right now please try these ones these ones are better:
"Vampire Overlord System in the apocalypse" OR
"My Vampire System"
Found a typo in the section after Kevin hears about the diving project on the news - I'm assuming "the project deeper" is supposed to be "the project keeper"
another thing . if you introduced a person on the top.. part of a scene.. wag mo ulit ulitin... like vladimir ordered burger... vladimir took a bite and liked it..
tenses of the verb.. using the same words... redunduncy...
try checking for possible synonyms... avoid filipinism... instead of putting why not use placing... yan po napansin ko sa first chapter... hope na ma improve mo sya
