After returning from the Lu State front line last time, Song Yuanli had only stayed home to nurse his wounds for a while before voluntarily heading back to Yinfeng Ridge to help the family guard the mine there.
Since the mine at Yinfeng Ridge lay deep within Yunwu Mountain, with no human habitation around it, it was frequently attacked by nearby demonic beasts. Thus, both the Song Family and the Carefree Sect attached great importance to its protection.
Not only had they set up a Grade 2 High-grade Defensive Great Formation at Yinfeng Ridge, but two or three Foundation Establishment Cultivators and over a hundred Qi Refining Cultivators guarded it year-round.
Even so, whenever they encountered a demonic beast rampage in Yunwu Mountain and the Yinfeng Ridge mine came under a mass assault from beast hordes, they would send word to the nearby Song Family for aid.
However, near Qinghe County, Yunwu Mountain was basically populated by Level 2 Demonic Beasts. In the past several hundred years, no Level 3 Demonic Beast or stronger had ever appeared. Whenever they sent the Song Family a request for aid, Song Yuanfang would handle the arrangements, and it was rare for the matter to reach Song Qingming, the family patriarch.
That was why Song Qingming had felt a trace of confusion upon hearing that the urgent letter had come from Song Yuanli.
Could some formidable Level 3 Demonic Beast have appeared near the mine?
Thinking that another crisis had emerged at the Yinfeng Ridge mine, Song Qingming picked up the letter Song Yuanli had sent and opened it. After one glance, his expression shifted several times, and he looked up at Song Xuanfeng before him.
"Have you confirmed that this letter came from Yinfeng Ridge?"
