There are some errors in the text, which have been revised.
Today, when the author was reading the previous chapters, I found that thest request to upgrade to an intermediate kingdom mentioned in the chapter on upgrading the Summoning Gate was written as "Conquer 2 elementary kingdoms that are not under the scarlet lord (0/ 2)'', this is a mistake of the little author, it should be ''conquer 2 primary kingdoms under themand of the scarlet lord (1/3)''.
That is to say.
Next, the protagonist only needs to conquer two primary scarlet kingdoms to advance to the middle-level kingdom.n/o/vel/b//in dot c//om
It has been modified now, just refresh it.
In this month, the author will add more updates to this question.
I wish you all good health, smooth career, harmonious family and happy mood.
(It’s even worse in the past few days, because I have to apany my father-inw to Changchun Hospital to see a doctor.)
