In such a situation, even though Northern Zheng and Jin Country had temporarily submitted to Tang Xu, playing the role of puppet emperors,
it was impossible for the Two Countries to easily devour Yuzhang.
The only way for them to consume Yuzhang was to imitate Wei Country.
With overwhelming strength, they would gradually nibble away until all forces within Yuzhang were eliminated, achieving the goal of taking control of Central State.
Currently, Northern Zheng and Jin Country's submission was merely to stabilize the two strong adversaries in The North temporarily, removing the threat to their own northern borders.
At the same time, they sought to use the opponent's power to actively attack Nanzheng in the south, to gain more living space and strength.
Then they would turn around to face the two strong adversaries in the North in a decisive battle to the death.
The contradictions between Both Sides were irreconcilable.
