Never before had Du You felt that his path to advancement was so difficult. Initially, some of the nodes were relatively easy, but the later stages became more troublesome because finding nodes was increasingly challenging.
Moreover, every node's establishment required Du You to carefully deliberate and continually calculate.
Now, the framework being constructed was an eighth-tier one, because afterward, this web of laws would continually extend with numerous branches, constantly building nodes, which is a process of elevating oneself to the eighth tier.
Similarly, these lines need to be as dense as possible because gaps will affect subsequent advancements.
The best method is to finally construct a complete sphere, so the current framework must be perfect. Any issue would inevitably lead to large gaps in this sphere in the future.
Although the materials don't show much, Du You knows this would affect the progression to the ninth tier.
