The big barrier was B rank, even though in theory A and S rank are harder, once MC sees first A rank evolution it doesn't take long for a bunch of S classes

The MC learning in India there is a zombie who is spreading a new super infection. And MC just ignores it. Despite the whole world ending in just a year from the original infection yet she ignores the super infection

Lin Xiwan is clinging the her sister, jealous if someone looks at Lin Jiayao, while also having the same "pe*verted starr". Also She embraces Lin Jiayaos disabled legs while sleeping and Lin Jinyao mentioned that her sister would use her as a bodypillow, if it wouldn't be to uncomfortable. There are some kisses on the forehead and a lot of hugging and princess carry

In chapters 72-76 between the massacre, the older sister is in a beastly rage induced by mothdruggs and tears her younger sisters cloths apart before falling asleep. After waking up, she only sees her stripped and bruised sister lying on her and the only thing she remembers is a "pleasurable dream". Lin Xiwan doesn't deny that she would do something but is only concerend if her sister would be disgusted of her

The washing scene a bit later is to much to write it here^^

I haven't read more but I think after their misunderstanding Lin Xiwan will become bolder, as her sister hasn't denied her approches

Lin Jiayaos zombie develops a new ability through blood crystal consumption -> Lin Jiayao can learn a related ability, e.g. Her zombie consums a sprinter (pysical strong), Lin Jinyao can learn "Vigor" to help her regenerate her energy faster

e.g. The sprinter zombies have large muscles without skin all over their body or her hive zombie girl whos eyes are gone (it is described how she lost them, nightmare fuel on it's own) and instead she grew a beehive like structure in the eyesockets, to grow little fly things that can controle other zombies, give intelligence and are a scouting device

tldr: Basically no fighting at the higher ranks and the finally enemy surrenders without resistance.

There is a typical level up system from E to S Rank with clear conditions to rank up what is fine as the stages are defined and even 5 B-Ranks can't defeat an A-Rank. At the end, to no ones surprise, Lin Jiayao becomes the first "absolute beeing" with her mental strengh maxed out and in addition to that she ranks her zombies and a few friends up to S-Rank to prepare for the final battle, that is also fine. But what I don't like is that instead of a final S-Rank clash like "Sung Jinwoo vs Thomas Andre" or "Sung Jinwoo vs the Monarchs", we get a complete surrender of the enemies without even a bit of resistance. Bjt that isn't even the worst, after Lin Jiayao and her Zombies become A-Rank or above there is basically no fighting anymore, just rushing to S-Rank and the end. It took Lin Jiayao very long to get her Zombies slowly leveled up but at the end 5 are done in 1 chapter, no struggle for ressources at all.

tldr: The gl is to much to ignore it and to less to appreciate it.

Lin Jinyao is completly indifferent to romance, even after all her problems are resolved, she ignored everything from anyone. Now let's start to go into detail:

Like I said before, the sister Lin Xiwan has an extreme sister complex, that goes way far over sisterly love. A few examples she dresses her sisters up in the typical le*d outfits (maid, japanese swimsuit, etc). They hug, kiss and have a very intimate close connection (remeber this is still chinese, so they have more restrain in their culture than we westerners xD) She wants to destroy her sisters and her own "reputation", so that they can't get married. Lin Xiwan dreams about her sister and if it was innocent, she wouldn't be ashamed of them and there are many other things.

But that is just the sister, we could easily add a harem tag to this novel, when we already keep the gl and in*est one, as they all stay in the same limbo of could be or is completely wrong.

I will list every girl that has "special" feelings for our MC (hope I don't forget anyone)

1. The sister, Lin Xiwan (no surprise)

2. The daughter, Hua Yibai (mentioned more than once that it could be also to "reproduce" and mushrooms have another sense of this situation than we have.

3. Japanese cult girl, Ruxue Feihong (first sees her zombie as a god, afterwards wants to bear Lin Jiayao child, thinks she got pregnant by a kiss (jup she is a child that never got a proper education because of the apocalypse))

4. Blue Snake (wants to lay eggs with Lin Jiayao (way more innocent than your thoughts^^))

5. A+ Rank cultivator girl from another world, Yunina (hope the name is right, mtl makes it difficult, I have read at least 5 different variations of the name) (they nearly got married because of a misunderstanding but Yunina still has feelings and looks forward to the future with her "wife")

6. Indian beauty, Sharma (She got saved by Lin Jiayao, in zombie form and afterwards sees her and wants to marry her or if it is not possible just be her dog)

7.+8. Black and beige mushrooms, cookie and cheese (get charmed by Lin Jiayao and want to get closer, but are stuck at the maid rank, and like Yibai, they think differently to us).

Now we have them all, and despite all the feelings thrown her way, Lin Jiayao does nothing and in the end she just goes traveling the universe with her sister and Yunina but there is no development, maybe a few extra chapters to clarify would have been nice than this limbo of suspension. I just don't like it when you have all these romance feelings/plot strings thrown around and they don't lead anywhere, don't show them in basically every interaction chapter or have them connect in a some way at the end.

romance and a final fight
