Chapter 721: Chapter 721: The Destruction of the Four Strongest Shinobi Sects!

"Where did that kid go? He's not here anymore?"

Fūma Katsumi asked suspiciously.

Kurohane Ryūga sneered, "With the attack we just launched, that kid must be nothing but ashes now!"

Fūma Katsumi nodded, thinking it made sense.

They had performed their strongest killing move, making it impossible for anyone to withstand it.

However, at this moment!

A resounding voice came down from the sky!

"Who did you say was reduced to ashes?"

Hearing this voice.

Fūma Katsumi and Kurohane Ryūga looked up into the sky.

Unexpectedly, Boris Moore had leapt up to the high altitude above.

Moore glinted with purple shimmer, his clothes whipping in the wind, his medium-length hair floating behind him – he looked like a genuine immortal.

Although Moore couldn't yet fly, he managed to momentarily hang in the air; although, it would last only a few minutes.

To truly learn to fly, one must become a real Earth Immortal.

"Last move. Prepare to die!"
