A Boundary Stone was a stone left behind when a cultivator with a vast Small World perished under the assault of Dao Dissipation Power. It contained incomparably pure Dao Dissipation Power. A cultivator who refined a Boundary Stone could not only master Dao Dissipation Power, but also expand the scale of their Small World. Most importantly, controlling their Small World would become far more effortless. Ling Tian and the others had known this for some time.
Now, after comparing notes, everyone naturally understood that the reason Ling Tian, Fairy Meng Shang, and the others had Small Worlds much larger than those of ordinary cultivators was that they had refined Boundary Stones.
"Exactly. It must be because of the Boundary Stones," Po Qiong said, his tone certain. "A Boundary Stone is originally formed from a cultivator's Small World, compressed into miniature. It contains the rudiments of a Small World. Once it's completely refined and fused with one's own Small World, the Small World's scale naturally increases greatly, and controlling it becomes much more effortless."
"Then why hasn't Little Book sensed a limit, when Aunt Meng Shang and Uncle Wu Ling have both faintly sensed one?" Mo Lei asked, puzzled.
"Besides the fact that my cousin refined a Boundary Stone, it's naturally because the way he cultivates is somewhat different from ours. His control over his mind has always been stronger than ours, so it's only normal that his Small World is larger," Mo Yu said gravely.
"Looks like that's it." Everyone nodded. Then they began thinking about Boundary Stones. After all, refining one brought many benefits.
"Though refining a Boundary Stone brings many benefits, you first have to get one. These things are rare treasures that can only be found by chance, and even the Nine Great Superpowers rarely obtain them,"
