I'm not sure which novel you're referring to because I don't know what exactly you're referring to by the "Primordial Dragon". If you can provide more information, I will try my best to answer your questions.
If the male protagonist had a flood dragon and nine tails, it usually described a character with a special physique or talent. The flood dragon was a legendary divine beast that was usually believed to have great strength and special abilities. The Nine-Tailed Fox was a mysterious demonic beast that was said to possess infinite strength and intelligence. These creatures were often regarded as representative characters in novels with powerful and mysterious abilities. If the male protagonist had a flood dragon and nine tails in his body, it might trigger some special events and challenges. For example, he might have powerful strength and special abilities to deal with all kinds of difficulties and dangers. They might also face threats from divine beasts and demon beasts and need to rely on their own ability and wisdom to deal with them. The description of a dragon and nine tails in the male protagonist's body usually involved some mysterious elements and special physiques, which brought a lot of imagination and fun to the readers.
It's not like I haven't learned anything about novels. However, according to common knowledge, a dragon soul usually referred to a supernatural power or creature that was commonly seen in novels. The protagonist might have obtained this power in some way and become the corresponding dragon soul.
The protagonist of a fantasy novel had an ancient dragon, which was usually a supernatural existence with extremely high strength and intelligence. Ancient dragons were usually powerful mythical creatures or mysterious existences with powers and abilities that surpassed humans. In some novels, Ancient Dragons might become the protagonist's pets or companions, providing help and support to humans. The existence of an Ancient Dragon usually brought many difficulties and challenges to the protagonist, but at the same time, it also brought many unique experiences and rewards to the protagonist.
I recommend the "Berserk Dragon Slaying System". The male protagonist, Su Long, transmigrated to the Holy Dragon Continent. His body contained the power of an ancient dragon. He held the Dragon Slaying Tower and carried the Dragon Whip on his shoulder. He slaughtered the dragon and began an intense adventure with the female protagonist of different races such as the Fire Red Dragon. I hope you like this fairy's recommendation. Muah ~😗
I recommend the book, Orc Arena, to you. The protagonist of this book is very similar to the novel you mentioned. He also transmigrated into the body of a green-skinned orc and obtained the Gladiator System. He obtained their abilities by defeating other orcs. There was also a scene where after the fire dragon was defeated, the protagonist accidentally burped and released a dragon breath. You can take a look at this book. You might like it.

If the main character in the online game novel had blood poison in his or her body, it might mean that he or she had experienced some form of poisoning that caused some kind of damage to his or her body and thus infected with this poison. In the novel, this blood poison could be a malicious plug-in or a drug in a game that had some magical effect. The protagonist may need to seek medical help to treat his/her symptoms of poisoning. This might cause the protagonist to encounter other players in the game and develop some poison-related plots. At the same time, the health of the protagonist would also have an impact on the game. He might lose some skills or props and need to fight or negotiate to make up for these losses.
I didn't know that the dragon in my body had awakened.
I recommend "Godly Doctor and Soldier King". The protagonist of this urban supernatural novel is a small farmer who accidentally obtained Shennong's Mystic Jade and embarked on the peak of his life. There was still a dragon living in his body. If she liked it, she could go and take a look. I hope you like this fairy's recommendation. Muah ~😗
