When Sheng Xueqin took out the jade card from Guxin House, Shi Gan's expression changed immediately.
That jade card was crystal clear, engraved with the three characters of Guxin House, and there were special runes flowing on the jade card surface. This was a unique technique of Guxin House, which could only be performed by those of the Guxin Family's main lineage, and no one could forge it.
Moreover, Shi Gan also noticed that the level of this jade card was very high; it was at least controllable by the real high-ups of Guxin House.
He hadn't expected that Guxin House would give Chen Yuan a high-level jade card.
Some ordinary cultivators might not know the terror of Guxin House, and even Shi Gan only had a partial understanding.
But even this partial understanding was enough for Shi Gan to recognize the power of Guxin House.
