These five men were very fast; Jiang Yi had followed them for a while and soon lost them. He did not dare to use his Power of Heaven and Earth recklessly; the last time he had used it, he had suffered the side effects for several hours. If it wasn't for the yellow sand worms protecting him, he would have been killed then.
He also didn't dare to bring Xiao Leng out. It wasn't because he couldn't trust Xiao Leng; he just didn't want too many people knowing that he could control the yellow sand worms. If not, that would attract many formidable martial artists' unwanted attention to him. Furthermore, Xiao Leng's injuries were pretty severe. Jiang Yi decided to let Xiao Leng recover inside the Chaos Essence Pearl longer.
