First of all every doomsday portal they enter is a parallel world. All of them are apocalyptic. So why does it have to be real countries? The author could have easily made up countries but noooo.

It starts with praising the fatherland here and there. Then you start seeing that everytime anything catastrophic happens or a base falls or people f*ck up, it happens in America which servers as a reminder for our protagonist. Then some of Europe and India and other countries follow to be destroyed as the 'Fatherland' figures everything out.

When people start gaining power cause of the doomsday gate the Americans captured the guy and did human experiments but fatherland is soooo good, the most humanitarian and would never do such a thing.

Atleast the animal part of the novel was left out this crap until the giants arc. Every other animal's power is within a normal range while the panda's is mythical... Yeah, it only activates when there is extreme circumstances but come on. They are in a parallel apocalyptic world.

In the giant arc, animals start becoming bigger and bigger and the biggest ones have nucleus inside them. If other's nucleus is eaten they become even bigger. And in the end they start fighting over the nucleus and become berserk.

This could have been handled in so many interesting ways but in the novel, animals becomes as huge as a quarter continent, starts destroying everything and ofcourse other countries gets smushed. The MC becomes a huge panda and defeats all the other animals as all the citizens cheer on for their national treasure....

And towards the end only the MC and ML have the means to retrieve core fragments of the other worlds and only they know the information required and when they say it the other countries are sceptical so MC berates them (like dude they don't even know you, they don't know you have special powers and you didn't tell them that you contacted the world consciousness for the info).

Only the Chinese have cleared the highest number of doomsday gate perfectly. (Like duh. Cause the MC can turn in animals with powers. Honestly none of that would have been possible for a normal human.)

And the countries realise the seriousness after getting an earful from the MC. They try to retrieve the cores but find that it very tough for a normal person to do so. Some proceeds to be too proud while others ask for help. (I stopped reading at this point.)

Just saying, although Russia was mentioned it wasn't treated badly as the other countries. The author is very aware of the geopolitics huh.

And these are just a few from the top of my head.

the gratitude of the African soldiers and the people to Gou Fugui and Xie Tianwolf is much simpler-

All of them surrounded Fugui'er and Xie Tianwolf in the middle, and then danced around them for more than an hour in a passionate and cheerful dance, which felt like they were worshipping them as gods

Especially the husky × wolf. I can't contain my laughter every time I remember this. Iykyk.
