Zhang Yu considered it. If he started from the principle of causality, Li Fuyuan would inevitably be involved.
If Li Fuyuan acted once more, there was a certain chance he could break this thing.
But this differed from the previous situation. Earlier, they had been in Origin Void, and that strand of qi had also collided to some extent with the chaotic qi drawn toward it, so Li Fuyuan himself had faced no real danger.

If he went into the Great Chaos, he might be dragged in himself and merged into one with it. Thus, while there was a chance of breaking this qi, the likely price would be Li Fuyuan falling into the Great Chaos.
Not to mention that Li Fuyuan undertaking such a thing was by no means certain to succeed—even if he truly could accomplish it, Zhang Yu would not let him do so. Li Fuyuan recognized Celestial Xia and could be considered one of its people; naturally, he was a fellow Daoist. Given a choice, Zhang Yu would never allow a fellow Daoist to make such a sacrifice.
He had to seek another method.
If he continued to ponder along the principle of causality, he did see one possibility.
Changes in things generally went from simple to complex. The earliest changes were exceedingly simple, but later they became increasingly complicated, with more and more variables involved, until there were countless tangled threads, difficult to sort out.
For instance, when Heaven and Earth were opened, one could initially say, "One gave birth to two, two gave birth to three, and three gave birth to all things." Yet one could see that the further things
