Exception

The incarnation of Sasuke Uchiha's dark side was growing stronger and stronger; it had even brought out Susanoo.

If this continued, there could be a major risk.

At this point, it was already too late for Sasuke Uchiha to shatter the mental space created by the Waterfall of Truth through brute force.

Although the dark-side incarnation opposite him was still weaker than Sasuke Uchiha, it had gained enough ability to resist. Empowered by the Waterfall of Truth, it was growing stronger and stronger.

If Mizuki had been here, he might have concluded that although Kumogakure's forbidden ground differed somewhat in nature, its function was actually rather similar to the Mangekyō Sharingan technique of Kabuto Yakushi.

It determined one's own combat strength according to the enemy's mental state.

This special ability to grow stronger against stronger opponents was indeed a devastating weapon when used well.

However, the Waterfall of Truth's limitations were simply too great. It was far less useful than Kabuto Yakushi's Mangekyō Sharingan. The ocular technique Sukunami was nowhere near as slow and difficult to activate as the Waterfall of Truth.

The Waterfall of Truth had virtually no practical combat value; it could only serve to temper one's character.

Since the dark-side incarnation opposite him had revealed the power of Susanoo, Sasuke Uchiha could no longer afford to be distracted and halfhearted. A similarly pale-purple Susanoo appeared, but it was taller and more complete than the one across from him.

The moment the two giant warrior phantoms appeared, their first violent collision sent a considerable tremor through the Waterfall of Truth's mental space.

"What are you still hesitating for? If I help you, your power will definitely increase greatly. With war about to break out, you can absolutely achieve your goal and make everyone fear the Uchiha clan's power."
