After hearing this, Goku and the others understood a little more.
"Marshal Canopy and Goku happen to be able to absorb baleful aura, which is why the Curtain-Rolling General fought you," Uchiha Shin continued.
Now that everything had been explained, everyone understood.
Although what Curtain-Rolling had done was not ideal, it had been unavoidable. Otherwise, how could they have him eliminate the baleful aura?
There were very few people in the Three Realms who could absorb baleful aura. Finding two here was already quite fortunate. If they continued to nitpick and delay, they would only endanger the Curtain-Rolling General's future and his life.
"Curtain-Rolling, what is this Heavenly Tribulation Array above the Flowing Sand River?" Goku asked.
"I'm not too sure either. There was no Heavenly Tribulation Array here before. It only appeared in the last couple of days, and I don't know who set it up," the Curtain-Rolling General said.
"Then this is troublesome. The heavenly tribulation has been set up here, making it difficult for us to fly across. And not even a feather can float on this river's water, so crossing through the water will be difficult as well," Goku said.
Although they could enter the river and swim, it was far too wide and vast. Swimming across it would be extremely difficult. Moreover, this was Weak Water—the longer one remained in it, the greater the drain on one's strength. They might drown from exhaustion before even reaching the halfway point.
Marshal Canopy and Little White Dragon had lived in water for years, so they could hold out longer. But even for the two of them, crossing this river would still be difficult.
Though the Curtain-Rolling General also lived in the Flowing Sand River, he merely slept there. Most of the time, he stayed outside the river.
