Seeing the terrifying True Qi fluctuation in Lu Tianxing's hand, Old Master Lu took a deep breath, suppressing the throbbing in his heart, and finally shook his head and said, "Tianxing, I know you want to help me. Undeniably, the quality of your True Qi is indeed very high. Looking across the whole world, there are hardly any who can match your True Qi quality. Even once you reach the Late Stage of Mythical, I would have to be wary of you. However, you are now only at the Middle-stage Mythical, your strength is still too weak. If you could breakthrough to the Late Stage of Mythical, relying on the terrifying degree of your True Qi, wanting to help me refine this Sword Qi would be naturally easy. But now, you are far from being able to refine this Sword Qi for me."
"Grandfather, of course, I wouldn't naively think that with my Middle-stage Mythical level I could refine the Sword Qi within you. This is just the beginning. Look at this, what is it."
