Li Xiaoya was so cautious because traveling alone through the Thirty-Three Greater Star Realms was indeed extremely dangerous. It was not merely because there were so many powerful cultivators, but because of a vague, inexplicable feeling. After all, Li Xiaoya was already a Great Cultivator of the Great Void Stage. In the Human Realm, he would have been no less than a true immortal. Especially after his vitality had increased dramatically, he kept feeling as though some danger was drawing near. He somewhat regretted agreeing to Huang Huatian's invitation to participate in the Yellow Territory Immortal Assembly, but since he had given his word, he would naturally keep it. He had several things to take care of on this trip. Upgrading the Fire Dragon Sword was one of them. Second Better had also said that he had made some progress in studying the Upper Realm's Artifact Refining techniques, so this was a good opportunity for Li Xiaoya to find him some materials to work with.
Although Li Xiaoya could have asked Huang Huatian to help find materials, he did not want to reveal too much about himself to Huang Huatian and the Yellow Ridge Gate, especially the fox-clever Fairy Cang...
There was another matter: Li Xiaoya had begun to feel a little afraid of the Fire Dragon Sword. This sword could upgrade itself by absorbing dragons' soul essences. It was already a Heaven-Opening Treasure, so what rank of treasure would it become if it advanced again? He had never heard of any treasure more powerful than a Heaven-Opening Treasure. He had asked the Five-Element Rainbow Ganoderma, but the Ganoderma did not know either.
Li Xiaoya had a feeling that upgrading the Fire Dragon Sword this time would cause a tremendous disturbance. He could not say why; he simply felt it.
