According to Immortal Taegu, the immortal Tribulation of water that Elder Niji was undergoing was called as the Three Phase Water Tribulation.
It involved the water attacking an immortal in three different phases.
The first phase was the heavy rain that would strike one's body.
The second phase was the sphere that would form around their body and try to drown them.
And finally, the third phase was what Elder Niji was experiencing right now. The freezing phase that would try to kill an immortal by freezing them solid.
One could even say that it simulated the natural cycle of water. It started with the spring rain that would fall to the earth. It would then gather into a lake in summer before freezing up in the winter.
"He… he's fine?" Immortal Taegu said in a shocked voice.
