Zhao Hai really did know about this matter. He had already broken down one of the divine Secrets Gu and obtained a large number of arrays from it. He had also added these arrays into the spatial spear. The spatial spear was now even more powerful. With the new gunpowder and the new arrays, the spatial spear was definitely much stronger than the divine Secrets Gu of the divine Secrets sect.
However, Zhao Hai didn't plan to tell the two elders about this. He couldn't show that he was too well-rounded. If he did, not only would he not win the favor of the two elders, but he would also be reprimanded by them. The two elders were the kind of people who only wanted to cultivate. They didn't want Zhao Hai to waste too much energy on these things.
Hence, Zhao Hai could only nod and say, " "Yes, master, I understand."
