A novel that seeks to be reborn into a beast in another world (not the cultivation world)

In a novel, the protagonist was originally a human or other creature in another world or a parallel universe. Later, for some reason (such as an accident or man-made operation), he was transported to another world. The creatures in this new world were very different from the humans or other creatures in this world. The protagonist had to adapt to this world and gradually grow into a powerful creature to carry out various adventures and battles. The following are some recommendations for novels about rebirth: 1. Full-time Mage series. The main character was originally an ordinary human, but he accidentally transmigrated to a magical world and became a powerful mage. 2. Battle Through the Heavens series. The main character was originally an ordinary person, but for some reason, he was transmigrated to a fantasy world and became a powerful martial artist. 3. The Douluo Continent series. The protagonist was originally an ordinary human. Later, for some reason, he was transmigrated to a soul master's world and became a powerful soul master. 4. Infinite Horror series. The protagonist was originally an ordinary human, but for some reason, he was transmigrated to an infinitely terrifying world and became a creature with infinite power. 5. The Sword Comes series. The protagonist was originally an ordinary human, but for some reason, he was transmigrated to a swordsman's world and became a powerful swordsman. These novels were all excellent otherworld novels with strong plots and character creation abilities, allowing the readers to immerse themselves in them and enjoy reading them.
