"Actually…. The reason my house is in this state is because-" In the end, he had decided to tell Feng Chen about how he had ended up blowing up half his house due to refining a demonic medicinal potion.
Of course, him suddenly confessing that he had been refining a demonic medicinal potion made Feng Chen shocked… But after listening to Elder Song explaining the reason why he had decided to make such a thing, Feng Chen's shocked expression slowly turned into one of worry.
The fact that Elder Song had sacrificed his own lifespan to make the demonic medicinal potion instead of using a live human sacrifice that most demonic potions or other kinds of demonic concoctions required, while it was a good thing in Feng Chen's eyes, as it meant Elder Song had not ended up becoming a demonic cultivator but was also something that caused Feng Chen to worry for Elder Song's health.
