After he left, old turtle opened his eyes and looked in the direction where Su Yu had left. There was some doubt in his eyes.
There was something unusual about Su Yu.
Old Turtle had seen the power of his bloodline. It wasn’t any special power. However, it was almost impossible for Su Yu to complete the 72 iron-eating forgings.
The seventy-two casting of iron was the most powerful technique of the iron-eaters.
Even with the bloodline and talent of the iron-eaters, very few people could truly complete the seventy-two casting. It was hard to say if there was still one. How could Su Yu complete it?
Also, how did he transform this body-forging technique into a body-forging technique that was suitable for human cultivation?
Also, that battle technique with divine runes was unusual.
Also... Many things were actually unusual.
