Jiang Yi did not take the second or fourth pathway, but the seventh one!
He jumped off the cliff quickly, not because he was seeking death, but because he found a big problem. Earlier, he had steered two Sword Emanations Race beings into the spatial zone turbulence. The two Sword Emanations Race beings were immediately reduced to dust.
There was nothing suspicious about that, but there was a problem with the dust. Since there was dust, it must have been suspended in midair. However, when Jiang Yi tried to feel the dust, they all disappeared. Nothing was left behind.
Dao Feng and the others did not smell any blood and realized that something was amiss. Jiang Yi's senses were even sharper while he was in the State of the Union of Heaven and Man. The dust should have existed in the world. Although one probably would not be able to spot dust with their naked eye, Jiang Yi should have been able to while in that state.
