The shadow explained patiently,
"The scripture your master taught you aims at distilling your flesh, which is good. However, you can't practice multiple techniques in a lifetime, because most techniques are incompatible with each other. But it's different for the devouring technique. You have the body born from all of creation, and thus can practice even the best of techniques. However, if you don't practice the devouring technique, then you can learn the technique of the Heavenly Dragon but that is all. Your body would be wasted with this technique. The mildest consequence would be that you are stuck in a lower realm, the worst would be death. Do you understand now? Even a pig could understand this."
Certainly, Xuanyuan understood immediately, he tried to give examples,
"What you meant is that even though the devouring technique appears to be a lowly ranked technique, there's no limit to its growth. However the technique of the Heavenly Dragon taught by the Yun clan would only be Tian class. That’s the limit for the person's strength development? If that's so, then I can find those with the strongest techniques and devour their power. Then I can use the devouring technique to learn the knowledge of every clan. Then I'll become the strongest man in the universe?"
"Hahaha, nice. You are indeed, quite smart. It was worth it to spend my power merging into your body. Even though you have already trained the Heavenly Dragon with Burning Scales and The Five Taloned Dragon, you can still learn the devouring technique. Fighters refine their skin, warrior refine their flesh, masters refine their bones, spirituals refine their veins. When you have your veins refined, then you can learn the method to release your fighting Qi. The more fighting Qi a technique can contain is determined by its class. You only need to devour other techniques to improve your own after you reach the wild realm."
The shadow was very happy with Xuanyuan. It is difficult to find someone like him. It took a step forward and put its hand on Xuanyuan's head and said,
"I am going to teach you the first few parts of the devouring technique, 'The Way of Absorption', 'The Way of Refining Flesh', 'The Way of Refining Bones', and 'The Way of Refining Veins'. These were all created by the first body born of all creation, the first Devouring Emperor. After I give the knowledge to you, my power will be exhausted. I will absorb part of the fighting Qi you refine, which will slow down your process, but this is the only way. Every time I show myself, it will take up a lot of my power. Unless you can find fighter stones, jades, crystals or something even purer, I won't be able restore my power quickly."
The shadow shone with a black light and merged with Xuanyuan's mind. The four ways of training suddenly appeared within his mind.
After that, the shadow became more transparent, Xuanyuan was worried asked,
"Are you okay?"
"I am fine. I will live. Work hard and go to the School of Yuehua. It'll be safer for you." The shadow smiled and summoned the sword lying on the ground. It looked at it and nodded.
"It's a nice sword and a spiritual instrument. Sacred instruments were also divided into many classes. The lowest is just a sacred instrument, the next class is spiritual instruments. This spiritual instrument is called "Sword of Swimming Dragons". The Swimming Dragon is a branch clan of the Heavenly Dragon. This sword was made from the bones of a swimming dragon. It lacks some refinement, otherwise it would have become an earthly instrument. You can use this for now."
Then it looked at the ring and released the binding on the ring. The shadow nodded and said,
"There are quite a lot of things here. You can put all of your money into this ring, it had about a single room worth of space inside. The best thing about the devouring technique was that it was made for your body. So you can train anytime. With that pearl given to you by your master, your training will be more efficient. Your master was really kind to you. The pearl is still a very useful thing even to someone of her rank, yet she gave it to you. It shows how much you mean to her.
