"Full-blooded brothers? Same father, same mother?!!!" Jiang Xinli's pupils constricted. Her mind went blank with a deafening ROAR.
She stared blankly for a long moment. "But you two... one's a snake, and the other's a tiger..."
The two of them never acted like brothers. Their personalities and appearances were completely different as well.
'Besides, if she recalled correctly, most snakes lay eggs, while tigers give live birth...'
Sheng Tianze gently kissed the back of her hand.
"Many years ago, Beastmen underwent scientific genetic modification. So, as long as the father carries a cross-species gene bank, it's possible for the gene fragments for both snake and tiger to be activated."
But only the Imperial Royal Family possessed the ability to carry such a cross-species gene bank.
To be precise, it had to be the legitimate eldest son with the right of succession.
This ensured both the purity and diversity of the Imperial Royal Family's genetic lineage.
