"What method?" Ye Mo asked impatiently. "Stop with the suspense and just tell me."
Saving Gu Xingyue was also saving himself. If Gu Xingyue's strength dropped immensely, even if they passed the passage, Invincible Ta Ba wouldn't let Gu Xingyue go. Invincible Ta Ba had always been oppressed by Gu Xingyue. Now that Gu Xingyue's cultivation had weakened, it would be a good chance for him to make a move against her.
Also, the brothers Man Tianhao and Man Tiancheng wouldn't want to let her go either.
"Do you have to ask me that?" Hong Ling gave a nasty laugh. "I already told you, if you want to know what to do, you need to think back to what you did inside the Demonic Cultivation Gourd."
Ye Mo suddenly remembered the words of Hong Ling. Fusing the Blood Spear Qi and the Black Spear Qi would create a powerful Spear Qi.
What had to be done was of course the so-called Conjoint Training.
