In terms of resource comparison, Zheng Yichen could never surpass the Dusk, even if he found the Primal Stone World, much less considering he still hadn't found it in the final moments.
As for spending a long time accumulating resources, that's just wishful thinking. No matter how much time he spent, even if he had a thousand years, the resources he could accumulate wouldn't compare to finding a Primal Stone World.
Therefore, when facing the Dusk, he could only use small to overcome great. In this process, the Oath Power he grasped, the Pain Feedback, and even powers like Oblivion and Life Creation, were cards to complete the final resource exchange.
What truly determined the final outcome was the abilities Zheng Yichen initially possessed.
In such a battle, his initial abilities were of no use, yet his extraordinary abilities were essential for completing the resource exchange with the Dusk.
If he didn't complete this exchange, he truly had no chance.
