After seeing the reaction of those cultivators she does not want to take a risk it is best to hide the real color of her hair still she gets strong enough to deal with those who have any problems with her.After that, Gu Hua sprayed some famous brand fragrance taken out from her space on her clothes to hide her smell. Since Nether Fire Bull can easily locate its prey by its smell. So it is best to hide her smell first and after stealing the golden dragon tree she would just change her clothes so that Nether Fire Bull would become confused when he won't be able to find her and she will take advantage of this opportunity to kill the Nether Fire Bull.After hiding her smell just when Gu Hua was about to go to steal the golden dragon tree. Suddenly, a thought flashed Gu Hua's in Gu Hua's mind, faint guessing a possibility in her heart.
