Li Moulian, 36, dragged Xu Fan, 21, out of her bed and bundled her into the back of his car before carrying out the vicious attack in Huizhou City of Guangdong Province, southern China.
The pair ended up side-by-side in hospital beds as surgeons battle to save their lives, but, despite the mother-to-be’s horrific injuries, her unborn baby managed to survive.
She fell pregnant by mistake after a one-night-stand, but the pair decided to stay together and moved into to a house in Mazhuang New Village.
Sixth months into the relationship, the pressure seems to have been too much for the father-to-be.
Moulian attacked Fan while she was asleep and dragged her out of her bed, telling her he planned to kill her.
He bundled her into the car and drove around the town before police were able to spot him.
