The Taicang had ultimately become history; the future domain would belong to the Great Wilderness.
Just as Tian Zi had said, Taicang was no more, and the Great Wilderness would rise. Since the Heavenly Dao has been established, it naturally needed to grow stronger, making the Great Wilderness Domain more powerful.
The followers of Taicang, like Old Man Xiao, were deeply attached to Taicang and couldn't immediately accept its transformation into the Great Wilderness.
However, Tian Zi's unique status, being closer to Taicang, combined with the cultivation of the Heavenly Dao, could pave a way forward, enabling growth and the chance for revenge in Taicang's name.
With this, Old Man Xiao and others wouldn't oppose as much.
After all, Taicang was no more, and if they could avenge it, what harm was there in changing names?
