Zhao Sheng did not continue.
The Huang Sha Taoist understood implicitly and transmitted his thoughts, saying, "If the overall strength of the Netherworld Ghost Realm is far less than ours, perhaps we could launch a counterattack and avenge the invasion from ten thousand years ago."
However, Zhao Sheng was not as optimistic as the Huang Sha Taoist. According to the records in the secret crypt of the Ksitigarbha Sect, the strength of the Netherworld Ghost Realm was very likely superior to that of the Tianzhu Realm, perhaps even more than just slightly.
One must remember that in the battle ten thousand years ago, it was the Tianzhu Realm that was invaded.
This could be seen from the Heavenly Burial Plain, which had turned into a land of sinister spirits within a radius of ten thousand miles.
