[8] In 1383, the minister persuaded the 15-year-old prince that Maha Dewi was planning to put her lover Maru on the throne, and that he would fully support a rebellion by Nwe.
When Maha Dewi finally ordered an expedition to Dagon in October, Zeik-Bye led the rearguard army, and undermined the attack.
[15][16] In the following years, the young king, who faced several internal and external threats, valued court ministers who could also take the field.
[note 4] By 1388, two ministers Dein Mani-Yut and Byat Za, who had proved themselves as successful commanders, had overtaken Zeik-Bye as the chief advisers of the king.
He was part of the embassy led by Byat Za and Dein to Siam to receive a white elephant for Razadarit presented by the king of Ayutthaya in the early 1390s.
