Looks like somebody's going to get their butt kicked.

Yes more Women's! Harem extended ;)

I'll add a bit of spoiler intrigue. At 3:54... say hello to fun relief all the way until the end of mortal realm and a bit further. Skeleton helmsman is one of most likeable characters in novel (well, him and his future buddy in arms... hmmm, and Fire and Ants)... it is one helluva nice and fun party. Also, with Skeleton helmsman there will be a lot of answers on ancient war

1) I think someone also manipulated the history cuz’ Demon Blood Sect was never wiped out actually. False rumors has been spread throughout the 100 Dynasties about Jade Dynasty’s fall.
2) Is Wei Dynasty now a Middle Dynasty or Upper Dynasty cuz’ King said Lower Dynasties get 3 seats while Central Dynasties get 10 seats.
3) Martial Emperor can’t enter in these secret Realm But HalfStep Martial Emperor can enter which help them to break through Martial Emperor Realm.
Just clear me 1 thing, is Is he meant Martial Emperor(9) or Martial King(7)? Cuz’ subbing was quite vague.

Sorry for late answer

1) They were wiped out. These are just survivors who either escaped the purge or survived with almost fatal wounds. Skeleton Helmsman for example is far from his best state. His boss is in healing coma. Chi Yan is in soul state, their leader is sealed in secret realm...
2) It was lower. Status is the same as level of highest Martial King (low, middle, high), so now that granpa leveled up, they can contend for middle empire. The reason why they can only get 3 seats is different. The few high empires pretty much enforce the rules (like they can send 100 people, middle 15 and low 3). Normally, Wei could get middle rank easy, but this time it is a problem because Wei upgrading means high empires can cheat less spots. How they cheat? Each of them pretty much forced 2-3 low rankers to lend them middle rank Kings, upgrade them and they take 12 spots. Wei is not their pawn.
3) Martial King(7) can enter, Emperor(8) as called in animation can't. It is a naming fuckup. Problem is that Sovereign(8) and Emperor(9) are pretty much same thing and animation took Emperor as 8... I wonder what 9 will be translated as (fun fact, tried using Google Translate and he translates both levels as Emperor)

wait. so they were just in the middle of a huge war with another country and suddenly it is over? Like yes they beat the invasion, but....that's it? the war is done? They gonna just ignore the million troops the other country has just gathered at the borders???

Considering the dean alone took out their best commander with hardly any effort, and they got a few other elders at martial king level plus each soldier is better equip than theirs, I doubt it's much of a problem.

5:38 no one riding lol

How nice of MC to try to get more seats for his followers.
