Chapter 577: Is Ning Fan Dead?_1

Lin Haifeng had been observing Ning Fan's strength during this period and he discovered something that terrified him.

In just fifteen short days, Ning Fan's power had at least doubled!

This was a terrifying figure, for once one entered the Great Grandmaster Realm, it was as difficult as ascending to heaven to improve even one step further.

Yet, Ning Fan seemed to be able to keep getting stronger, as if there were no limits!

To be the enemy of such a terrifying person would be a lifelong nightmare!

Lin Haifeng gathered his mind, not daring to think further, and also approached the light screen, launching an attack against it.

Four powerful attacks struck the light screen, causing the entire screen to tremble.

The ground beneath their feet also rumbled continuously as if it couldn't withstand such terrifying power!

…

The outside world.
