As a person of significance in the Three Realms, being suppressed by a junior like Ksitigarbha to such an extent, you can imagine the frustration in Patriarch of the Nether River's heart. He had originally planned to stealthily replenish his Sea of Blood, only to encounter someone like Lu Yu, a brash young man, who dared to make a move under his imposing pressure.
This also ignited a nameless rage within him; otherwise, with his current status and position, it would be beneath him to strike against someone like Lu Yu.
After suppressing Patriarch of the Nether River, Ksitigarbha turned to Lu Yu and said, "Patron Lu can close the rift here to prevent the aura of the Sea of Blood from polluting the Mortal Realm."
Lu Yu was startled. How did this Bodhisattva know his identity?
