Every supreme powerhouse from each faction had already run through the process of proving their Dao and becoming a True Immortal countless times, prepared numerous rehearsals, and even calculated every possible problem that might arise, while also devising contingency plans for those potential issues.
Just like at this moment, the supreme powerhouses of the Buddhism School were uniting to prove the Dao, hoping to achieve the Arhat Fruition through this. If the Power of Incense Fire supported a single powerhouse, it would naturally be sufficient. However, when several supreme powerhouses from the Buddhism School attempted to advance and prove the Dao together, their collective strength was somewhat insufficient.
Therefore, they had long prepared a contingency plan, which was to emulate the Pioneer of Buddhism. It was said that during the Buddha's Dao certification, he made great vows, with the operation of "boarding first and buying tickets later" to prove the Dao.
