Capítulo 1201: Cheating With A World Spark.

"According to this, a world is built with a realm heart as the foundation. Only an inhabitant of a realm who is an Origin god can see and interact with the realm heart. But only an inhabitant with a six-law concept can fuse with the realm heart to become a realm lord. So that's why Monarch High Heaven had to become an Origin god to become the realm lord despite being selected by the Mother High Heaven when he was a Sovereign."

This is the first time Legion is coming across information about the realm heart so all the clones are intrigued. The information states that the only way to acquire a complete realm heart is to become a realm lord. Even then, the realm heart won't be completely his. This is because there is a powerful Will that represents the interests of all living things in the realm and is bound by certain rules. 

The mental network of the clones increased in activity as they discussed.
