Ordinary Nine Nether Soldiers hadn't been opened up a Small World and couldn't wield Explosive Impact Arrow. But once their numbers grew too large, repeated Impact Arrow attacks alone would be enough to destroy the grand formation where Chi Xue and the others were hiding. So they still had to be killed. Fortunately, although there were many Nine Nether Soldiers, Chi Xue and the others could easily kill them by unleashing Space Shatter with all their might. Most importantly, a slain Nine Nether Soldier needed seven days to revive. In other words, if Chi Xue and the others killed off most of the ordinary Nine Nether Soldiers within seven days, they wouldn't need to worry about them anymore.
Of course, the most important point was that even if ordinary Nine Nether Soldiers formed the Buddha Kingdom World and the Myriad Sword Demon Extermination Grand Formation, their defenses still couldn't withstand the Space Shatter unleashed by Chi Xue and the others in unison. In particular, using Space Shatter twice in succession would be enough to kill many Nine Nether Soldiers. If Chi Xue and the others could also catch some Demon Soldiers and modified Nine Nether Soldiers within its range, then using Space Shatter once or twice more would be well worth it.
Just as Chi Xue and the others had reasoned, even if the technique consumed somewhat more energy, killing large numbers of Nine Nether Soldiers and Demon Soldiers made it worthwhile. This was especially true because it could mislead the Lord of the Universe and make him hesitate to launch the final battle rashly. As long as Chi Xue and the others suffered no casualties, then even if they used up more energy, it would still be entirely acceptable. After all, if he couldn't inflict casualties on them, the
