In the end, Peter Brown still bought the Extreme Fire Divine Thunder. Besides that, Peter is now nurturing the Soul-Breaking Spear in his brain, and nurturing the Star Energy Shield below his navel. This Star Energy Shield is also a great thing, refined by a Quasi Saint, and it can fully withstand attacks from anyone below the Quasi Saint Level. Having such a lifesaving item, Peter really isn't too worried about anything now.
Now, Peter even regrets a little. If he had known that such items were available here, there would have been no need to hide the fact that he possesses faith energy. If he had purchased it earlier, he wouldn't have been so passive on the battlefield.
When the shopkeeper saw Peter buy so many materials again, he reminded, "Peter, the Star Energy Shield indeed is a good thing, but you must never face anyone above the Void Saint Level. If they attack, it would only take three strikes from a Void Saint to destroy it."
