Supreme Treasure! Embryonic Form of the World! The Worry of the Lightning Tribulation!

Liu Yiyi's voice was filled with shock.

The reason for that was because she had just seen the peanut-sized transparent crystal quietly floating in the middle of Chu Feng's Heavenly Water Domain.

Upon closer inspection, one could see that there seemed to be countless floating shadows inside this small transparent crystal.

If it was magnified a hundred million times, one might be able to see that the countless afterimages were like the real world!

An incomparably vast world!

The Realm Heart was originally the seed of a world! The embryonic form of a world!

The Elementary Realm Heart was the best!

It was no wonder that Liu Yiyi was shocked.

Chu Feng looked at the Realm Heart in his domain in confusion.

"This thing… is so precious?"

Chu Feng felt helpless.

Although this was the only divine-grade reward on the Domain Golden Ranking List, he really did not feel that it had any use.
