First of all, everyone knew that the star river was filled with a mysterious and terrifying energy known as Extinction.
This strange energy possessed horrifying destructive power toward all living beings. Whether it was the physical body or the soul, everything would gradually erode beneath the influence of Extinction energy.
Even someone as powerful as Li Yun would not be able to survive there for long.
If he entered the star river with his current cultivation, then under the invasion of the Extinction energy, he would completely perish within less than ten breaths of time.
From this alone, one could imagine how terrifying that energy truly was.
Only experts who had reached the Spirit Manifestation Realm possessed the qualifications to barely resist the power of Extinction and survive within the star river.
However, survival alone did not mean safety.
The star river was recognized throughout the world as one of the most dangerous regions in existence.
