The basic battle prowess of the golems was the same. In other words, whether they were Mystery Realm Tier or Extreme Bone Tier, there wouldn't be much difference in power after fusing with the golems.
The difference lay in their own tier surpassing battle prowess. The higher the value of their strength, the greater the golem's power.
Ling Han first had to get used to every move after fusing with the golem. This was called compatibility. It was like a person riding a horse, and if he didn't get a good compatibility with the horse, he would very easily fall off the horse. No matter how fast the horse was, could it run?
Moreover, he had not entered into the palace anyways, and there was no death-light. Furthermore, he could only cultivate for half an hour a day, so he was completely in no rush.
It was unknown what material this golem was made of. When his body touched it, the rock was like water, soft and without force. His whole person sank in.
