The Green Wolf Mountain Master wrinkled his nose. "There's a sulfur smell. It should have drifted along with the sea currents... There really was an undersea volcanic eruption some time ago. It was probably caused by that battle."
"Even if an entire volcanic range had directly burst through the crust?"
Mr. Wugou shook his head slightly. "It has only been a little over a month, yet an undersea mountain range has forcibly risen. Though the mighty power of heaven and earth is unfathomable, such force should have affected hundreds of thousands, even millions of li around it, and lingered for a long time. It might not have settled down even after three to five months. Why was there no sign of it in the intelligence?"
All three were suspicious, yet they continued to dive, only to find utter silence along the way.
The great battle before the Four Tribulations seemed to have truly left its mark until now. This place resembled a silent world of ruins even more than the ten-thousand-li mist a million li away.
Yet both Mr. Wugou and the Green Wolf Mountain Master said that it had not been like this when they came years ago. Back then, after recovering and multiplying through the Four Tribulations, the surrounding seas had formed a fairly abundant ecosystem of undersea species.
