The Demon Realm's development over the past two thousand years had been remarkably fruitful.
Especially with the Dream Realm and the Lesser Thousand Worlds, the Demon Realm had produced more than a hundred Demon Kings.
Counting from the birth of the Demon Realm, only a little over fifty thousand years had passed.
Those two thousand-plus years, converted into the Lesser Thousand Worlds, amounted to over twenty thousand years.
That was equivalent to half the Demon Realm's total history.
Coupled with the Dream Realm's help in "simulating cultivation," opening up the path of cultivation in advance, how could such a situation possibly fail to bear results?
Not only had Demon Kings emerged—even more than a dozen Demon Sovereigns had appeared.
Among them, some were Demon Sovereigns from the past, while others had newly advanced.
Most gratifying of all, two Demon Emperors had emerged in the Demon Realm.
They had both been Demon Sovereigns in the past. When Zhang Yang had gone all out to raise the strength of Heaven and Earth, they too had caught sight of the power of the Void Origin.
After more than two thousand years of contemplation, they had finally broken through.
Now, Zhang Yang's divine sense had alerted every expert above the King Dao Realm.
Those familiar Demon Kings, Demon Sovereigns, and even the two Demon Emperors headed for Heaven Capital Peak as soon as they received the message.
Among them, the two Demon Emperors were actually somewhat displeased.
They were already Demon Emperors, yet he was treating them so discourteously?
But when they recalled how Zhang Yang had coordinated the development of Heaven and Earth two thousand years ago, inviting countless Emperor Realm and heaven-reaching great figures to help them glimpse the power of the Void Origin... even if they were displeased, they still came.
