Different Kalpa Passing methods abound. One of such methods certainly involves the use of magic tools.
However, this strategy has a prerequisite - the magic tool must be a dual cultivator's invaluable treasure and directly linked to one's primordial spirit. Both will bear damage equally, reducing the Thunder Kalpa's power while also strengthening the magic tool with the Heavenly Punishment invoked by the Lightning, thus converting danger into opportunity.
It cannot be a scavenged magic tool because allowing somebody else to intervene in your Kalpa Passing is tantamount to pooling two people to face the Thunder Kalpa. Therefore, increasing its power twice as much.
