Of course, coincidences aren't impossible. For instance, Zhouyang obtaining the "Qianyang Treasure Pearl" was an extremely coincidental event.
But when coincidences occur one after another, it certainly isn't a coincidence anymore.
The group of sand bandits that attacked the Baisha River Oasis, although none of them revealed traces of the Demonic Dao Techniques and Divine Techniques, Zhouyang repeatedly obtained Demonic Secret Techniques from their storage bags, which was enough for him to associate these people with the legendary Demonic Cultivators.
Of course, all of this is still just his speculation. The Demonic Secret Techniques he acquired can only serve as evidence for this speculation and cannot prove that the sand bandits are disguised Demonic Cultivators.
Since it's only a speculation, he couldn't directly report his conjecture as a factual result to the Chen Family Ancestor and Zhang Yunpeng.
