Silver Lamp would definitely not cooperate with the Natural Sect just for a few Dragon Gate Formation shopping cards.
She might not even have planned to cooperate with the Natural Sect in the first place and was simply plotting to ambush Ash and the others on a whim. Even with Ash and Harvey's Holy Sanctuary, if the Natural Sect attacked suddenly, it would be difficult for them to ensure the safety of Black Crow and the Swindler.
The sudden collapse of the ground also showed that Silver Lamp simply didn't care about the interests of the Natural Sect.
She just wanted to drive both sects into an arena and let them fight to the death to divert attention, then take advantage of the situation to seek greater benefits for herself.
From the very beginning, the Natural Sect and the Twin Sect were just sacrificial pawns in her plan.
