The Adventures of an Overpowered Knight in Another World - Chapter 36- Gwendolyn Elvina Odessa

The mighty void dragons are on the brink of extinction due to a strange condition. Their bodies have suddenly started rejecting their kind.

Due to that, Arad's mother dropped his egg into a forest where he could hatch safely, leaving him with a fragment of her consciousness and informing him of the condition of their race.

From that point, his goal became clear. To save their race by either mating a lot or finding a cure for their condition.

But, sadly, nothing is ever that easy. Arad is still practically a newborn and cannot tap into the terrifying might of his race, and his rarity makes him a prime target for mages and scholars seeking to study the dying race.

Son of the Senior Chancellor, Luo Wei, loved the wrong person in his past life. This mistake caused his entire family to be wiped out, and in the end, he was cast down as a pleasure slave, and died in the wilderness during the depths of winter.

Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

God plucked one of his creations from his first Earth and gave him a second chance in another one of his Earths...surprise it is in DxD! Now reincarnated as a perverted side character how will our poor protagonist handle his new identity? Well he probably wont make the choices you will want him to, that's for sure!
