For Shen Hao and the Human Civilization, this form of trial is also a first.
However, it's actually quite normal.
The higher level the war, the more straightforward and brutal it becomes.
There's no need for overly complicated tactics.
Sometimes, merely a technological breakthrough can completely turn the situation around.
Especially in the Extraordinary Domain.
Each life level evolution, or even each level's difference in extraordinary levels, brings a transformative change in power.
Frankly speaking, in such a situation, victory or defeat hinges on just one or two such changes.
And it is quite clear that the enemy indeed has some excellent hidden tactics.
At least, after Shen Hao initially surveyed the entire world, he found nothing, even after searching the depths of the world's Da Yuan.
After thinking it over, Shen Hao directly released all the other Level 9 warriors from his personal world.
