The Tongshen Realm can infinitely approach the Wanxiang Realm, but it can never surpass the Wanxiang Realm.
The reason the Wanxiang Realm is the Wanxiang Realm is because there is a qualitative difference from the Tongshen Realm.
The hardness of ten thousand sheets of paper stacked together can never surpass an iron knife.
Perhaps, when ten thousand sheets of paper are stacked together, they can resist the chop of an iron knife and not be instantly cut through, but the paper can never cut an iron knife.
The Tongshen Realm might be able to fight against the Wanxiang Realm, but it can never kill the Wanxiang Realm.
This is the qualitative difference between "paper" and "iron".
This is the perception brought about by a deep understanding of the Heaven and Earth Law.
Lu Yu possesses more than thirty thousand beginner-level laws of the Heaven and Earth Law, which may not be comparable to only a few laws but deeply understood at the peak of the Tongshen Realm.
