I saw this on MAL.
"According to Hara Yasuhisa's latest tweet, the manga is officially at its halfway point with the conclusion of the Rao Ai's rebellion arc, achieving unification within Qin. The second half of the manga will begin the week after next (from the day he tweeted) as Mr Hara needed some time plan for the second half of the manga. "

So how would you rate the first half ? I would give it a perfect score. This...
Kingdom has just reached halfway !
