The Invitation of Emperor NvWa

On the second day after he ended his secluded cultivation, Zhang Tie had received the ambassadors from Star Emperor Immortal Palace, Force Emperor Immortal Palace and Emperor NvWa's Palace. These people had been waiting for Zhang Tie for about one month in Dragon Emperor City.

Zhang Tie was crystal clear about the reason that the three top forces were eager to meet him so much. 

Superficially, the ambassadors of the three top forces were here to congratulate Zhang Tie for his military exploits in Nine Heavens Big Domain; actually, they were here to acknowledge Zhang Tie's current situation and his plan in the future out of fear.
