When he mentioned the word "invisible", his heart suddenly moved.

"Actually, the principle of invisibility is quite simple. The reason why people can 'see' is just because light shines on objects and reflects into people's eyes. Understand this, I only need to create a kind of light that will not refract.

The effect material allows light to travel along this material... and the invisibility effect can be naturally achieved."

After this idea was derived, Baili Qingfeng immediately put it into action.

At this moment, a deafening roar suddenly came from a mountain peak.

Immediately afterwards, a terrifying aura powerful enough to make people tremble went straight into the sky, swept by the strong wind, and surged from a mountain peak. Even though it was several kilometers away, Baili Qingfeng could clearly feel the aura on its owner.

The life force is so powerful that it far surpasses the strongest.

Not only that.

This roar stimulated Jingshan, who was already extremely vigilant. The entire Jingshan seemed to have poked a hornet's nest. Powerful auras rose rapidly and surged towards Baili Qingfeng. The number...

Hundreds and thousands!

"Discovered again!?"

Under the mountain peak, Baili Qingfeng was slightly startled.

He has obviously mastered the art of hiding and sneaking to the extreme, so why is he still...

"Wait, why did I say again?"
