Su Ping shifted his focus back to the Little Skeleton. According to the process described in the Antiquity Pet Contract, he bit his finger and slowly painted the Little Skeleton's forehead with his blood.
The Little Skeleton was still sitting there, absent-minded. It seemed to be oblivious of everything around it, but then the Little Skeleton reacted to the smell of blood on Su Ping's finger; a faint scarlet color appeared in its hollowed eye sockets.
The Little Skeleton slowly lifted its arm to reach toward Su Ping's hand, although the latter retracted his hand right after he finished painting the contract.
An intricate blood pattern was engraved on the Little Skeleton's forehead.
As Su Ping lowered his hand, the blood pattern disappeared bit by bit as if the Little Skeleton had absorbed it.
In the next moment, Su Ping felt an additional line in his consciousness that was linked to an external consciousness.
