Douluo: from Black Water Turtle to Sky-Swallowing Xuanwu

[Douluo fan + soul beast perspective + swallowing evolution + dark invincible flow] Lin Xuan traveled through the Douluo Continent, only to find that he had turned into a century-old black water turtle - slow in movement and with acceptable defense. It was the best target for a soul master to hunt for rings and could become the food of a thousand-year-old soul beast at any time. Fortunately, I have awakened the [Infinite Evolution System]. Evolution points can be obtained by devouring soul beasts, soul masters, soul bones, and treasures from heaven and earth! Black Water Turtle → Black Armored Turtle → Xuanming Turtle → Prison Suppressing Xuanwu → Chaos Sky-Swallowing Beast → Taichu Sky-Swallowing Ancestral Beast... From the prey on the outskirts of the Star Forest to the emperor who rules over all beasts; from the reptile at the bottom of the food chain to the supreme being who swallows stars with a thought and destroys gods with a glance! Tang San? Those are pigs raised by this king. Kill them when they are fat! God Realm? That is my king's dining hall, and all gods are prey! Since soul beasts cannot become gods, then I will swallow up this world of gods and re-establish the rule of heaven! Since humans regard soul beasts as prey, I will let the cavalry of all beasts trample through every city and make the soul masters kneel and tremble in front of the temple of all beasts! Extremely vindictive, decisive in killing, and swallowing if you don't like it! In this life, Douluo Continent has only one protagonist—— That is me!
