So, our protagonist is a boy with abilities to communicate with animals. In this novel, I found the beasts designed for the protagonist to be quite unique in chinese novels. I think the city is called Infinite City in the mtl which is the place where tamers receives resources and obtains traits which can be used to evolve their pets. Now, the novel still does not romance but it does have hint towards romance with another powerful female beast tamer. The Infinite City also allows the protagonist to challenges secret realm of varied difficulty- Novice, Normal, Abyss, Legendary. They also has artifacts for pets-weapons, armors and equipments. The MC eventually becomes a chef likely inspired by Shokugeki no Soma even from their over the top reaction itself which is extremely similar to the anime

The MC does not have an overpowered cheat like critical return or any system. But, he does have a relic from his parents which is a broken antler from the Sacred Deer, eventually revealed to be a descendant/messenger from a divine beast, Dragon of Life. The deer is currently in slumber and requires faith of people to restore its power. MC descended from a village that worships the deer and his relic can heal the injuries.

MC is kind of like an orphan which is adopted by his childhood friend, who is a female. But, no hint of romance, seems like a platonic relationship. The girl also becomes a poison beast master with her first beast is a heterochromatic spider that is also equally powerful. I said kind of an orphan because his parents are actually alive and working for an organization that is insistent to produce necromancer beast tamer, sort of tamer of the undead. But the flaw is they consumes soul of beast and will eventually becomes maniac.
The protagonist is a fourth generation beast tamer which is quite late in their beast taming journey. First generation beast tamers had evolve their pets close to overlord level (in the mtl). The one with hint of romance with the MC is a tamer of the first dragon in the world of Blue Star meaning she had evolved the first dragon from her pet. She is a powerful tamer.
The setting is about a world which is about to undergo a global mutation. The beast master receives a black card which will be used to contract a beast of their choice. Our protagonist owns a Husky which he kind of adopts in the story. It is later revealed the Husky is actually an experimentation by people from the Blue Star intending to create a strong initial pets. Thus, it kind of have a traumatic experience which it eventually overcomes. So, the protagonist saw a post about someone receiving the black card which he eventually also obtains one.
Let begin with the first beast the protagonist used which is a Husky, that learns to use the sword. It is highly likely to be inspired by Zacian from Pokemon with the beast capable of using sword abilities. In the last chapter I read, it reached quasi legendary level after evolving and can use a domain of swords. Next one, is a mutation of possibly a red eyed lizard, I am not sure exactly what species it is but it evolved into a dragon focused on defense since it is a big coward. It is the third dragon beast from the Blue Star. Because the second dragon is evolved from the Tyrannosaurus. It is revived by Eagle Federation (essentially the United States). Hint of toxic as in racism. But, nothing much since these countries are sort of not undermined. The second beast is naturally afraid of everything since it is a lizard. It is likely to be inspired from the anime Bofuri which explains its focus on defense. Thus, I find it extremely interesting how the author adapted ideas from possibly varied types of anime to create possibly a unique squad of monsters. The third beast is a dark crow that can use curse. Not sure, where the inspiration comes but the crow came with the abilities to curse someone. I think likely to be from Naruto where Itachi often comes with its crow which I suspect to be the inspiration since Itachi also uses illusory abilities from his Sharingan. Overall, each of his beast is unique.
The comedy is each pet kind of have a self mutilation tendencies. The dog has a powerful skill when released, kind of a wind blade that will break all of its teeth. The dragon has a skill that reflects all of damage it receives. To receive the powerup, his pets will attack the dragon to maximise its attacking prowess. The crow is also a funny one. His trait is Eye of Evil God which is a powerful trait to see someone far away and curse them. The payback is it eyes will be injured. But, he will heal them with the deer antlers so like nothing too serious occurs to each of his pet.

except for that one time about his parents
