But this oath was not only to restrict the loyalty of Old Zeng. Its bigger purpose was to act as a merit of contributing service and pushing forward the cause.
When the immortal spirit of Immortal Gou Chen rushed over before, he shouted for Immortal Monarch Wei to save him. The title of Immortal Monarch, is not used casually, especially in special circumstances.
At this moment, it was like the founding emperor of the mortal world who has conquered a vast territory. But Wei Cheng himself did not comprehend this, or even if he understood, he couldn't proclaim himself to be an Immortal Monarch.
What would that look like?
Qi Mei and others knew even less about this.
So they wouldn't call out that title either.
The old chap Gou Chen wanted to act as a loyal minister, but he ended up dying. Now, it's Old Zeng's turn to be that loyal minister.
Therefore, this oath of heaven and earth is not only for Old Zeng but also for the reality of Wei Cheng being an Immortal Monarch!
