Boom.
Lin Feng tried to nurture a Chiliocosm Sovereign-level Boundary Stone. He had never nurtured a Chiliocosm Sovereign-level Boundary Stone, but Boundary Stones no longer held any secrets in Lin Feng's eyes.
Coupled with the rough description of some Chiliocosm Sovereign-level Boundary Stones, Lin Feng already knew the approximates of the Chiliocosm Sovereign-level Boundary Stones. Hence, this time, he mobilized the entire small chiliocosm to give it a try.
As Lin Feng mobilized all the rules in the entire small chiliocosm, immediately, the rule power and the small chiliocosm power began to vaguely nurture something.
However, just as Lin Feng was about to attempt nurturing it, he felt his internal small chiliocosm shake violently. In that brief period of time, the remaining little amount of small chiliocosm origin in his body had been exhausted. If this continued, he would probably damage the small chiliocosm.
