The Western Heaven Battle Emperor did not hold back.
Though he did not know Lu Yuan's true strength.
He knew Lu Yuan's identity and position.
Strictly speaking, kings did not meet kings—a principle that applied throughout the Myriad Heavens. The reason such a saying existed, and why it was accepted across the Myriad Heavens, lay in the tangled web of forces throughout the realm. It was a reluctant compromise.
A king.
By the definition of the Myriad Heavens.
Was the strongest individual within a faction.
And also that faction's trump card.
Before the trump cards entered the field, conflicts between any factions would abide by the basic rules of the game. In other words, those below fought those below, while those above did not move. Even if they remotely directed their subordinates into battle, what they competed in was still the art of command.
Including their grasp of every opportunity.
After all, uncontrollable factors often arose in such conflicts.
It could be said that the "king" in kings did not meet kings existed as a safeguard.
To ensure that, after a defeat, there would still be a chance to rise again.
Of course.
The premise of kings not meeting kings was that both sides were on the same level.
Take the Luo God Clan and the Blood God Clan, for example.
Why had Xue Lingzi stationed Xue He, a Lower Earth Supreme, along the northern defensive line, ensuring that if Luo Tianshen headed south, he would receive word in time and swiftly respond?
Because if kings met kings, one of them was bound to die.
Either Luo Tianshen died.
Or Xue Lingzi himself died.
Or both died together, with one dragging the other down with him.
Therefore, to avoid such an extreme outcome.
When facing opponents of the same level.
