He no longer resisted the assault of the Dao Tower's power with his own Tao Domain as he had before.
Instead, he attempted to merge with it, continuing to evolve the mutual generation of the Five Elements of heaven and earth.
There was no mutual overcomning.
That was because the intense energy of the Five Elements of heaven and earth mutually overcoming each other was too fierce for Su Yu's Divine Soul and current realm to bind and control.
If it were only the embryonic stage of the Tao Domain, it would have been fine.
The moment Su Yu had begun experimenting with the great accomplishment stage of the Five Elements' mutually overcoming forces of the Tao Domain, he nearly obliterated himself.
Afterward, in the subsequent layers of the Dao Tower's space, he only dared to evolve the Five Elements' mutual generation of Taoist powers.
There was no obstruction or bottleneck whatsoever.
