"By that time, with the ample supply of resources, my strength will surely rapidly increase. Opening a few more fortresses, I might just reach the Divine Realm by the end of the fortification."
"Once I reach the Divine Realm, coupled with the merits of opening fortresses, I will definitely have the opportunity to apply for the chance to obtain supernatural fruits."
There are five major realms in the way of the Dao, and although I am only at the second realm now, Wang Wu had calculated the huge resources he could reap from opening fortresses. He felt that if he could seize this opportunity, there was a chance for him to reach that step.
Another reason is that Lord Li Ming is so strict about the distribution of the supernatural fruits because there are people around him who need them. However, the people around him, or the target group, would eventually reach the threshold.
That will inevitably relax the restrictions a lot, and that will be his opportunity.
