Soon, Liu Yan set up the array formation and activated it.
The purple six-pointed star array was emitting a purple light.
Liu Yan dripped a drop of his blood into the formation, and the Withered Tree Spirit King dripped a few drops of the liquid that looked like blood and wood shavings from the wound.
Suddenly, the purple hexagram shone brightly. It enveloped Liu Yan and the giant Withered Tree Spirit King.
After some time, the purple hexagram gradually disappeared, and they signed the soul contract.
After signing the contract, Withered Tree Spirit King became Liu Yan's pet. Liu Yan could sense the existence of the Withered Tree Spirit King, and they had also achieved a mind link, so Liu Yan could roughly understand its thoughts.
At this moment, Withered Tree Spirit King was a little happy. Not only was it happy that it didn't have to die, but it was also glad it had met a rare talent like Liu Yan.
