Facing Madara Uchiha in battle required tremendous nerve, even with a group of fairly capable comrades at one's side.
Even though Mizuki had acquired the Byakugan early on, he had no means of combining a large number of Byakugan to form a Tenseigan, nor was it realistically possible to forcefully enhance the Byakugan with an enormous amount of chakra.
Even if he had possessed the means, spending it on the Byakugan, which was not a core source of power, would have been less worthwhile than improving Dreamplay and completing the system of rules within it sooner.
Thus, from the very beginning, the Byakugan had been destined to serve only as an auxiliary power and could never become the focus of Mizuki's development.
And now, Shinzhen could not evolve the Byakugan into a complete Tenseigan either.
However, with the Caged Bird working in conjunction with it, destruction before rebirth was possible. As long as the Cursed Seal was forcibly shattered, the Byakugan could receive an enormous enhancement.
Tenseigan Chakra Mode was a power no weaker than the Rinnegan. Though it was less versatile than the Rinnegan, its destructive power was even greater.
In Tenseigan Chakra Mode, the Golden Wheel Reincarnation Explosion and Silver Wheel Reincarnation Explosion were terrifying secret techniques capable of ravaging the moon itself.

If time passed and the Byakugan continued to grow stronger until it ultimately reached the level of the Tenseigan, then naturally none of this would
