Mastiff!
A Poison Spider S-rank expert.
He's also currently among the top five on the global wanted list!
It could be said that he's the only person in the world who has assassinated fifteen people without being discovered at the scene.
His danger coefficient is extremely high!
Gu Er had encountered Mastiff once!
That time, both he and Mastiff were injured in the duel!
Since then, he had never seen a trace of Mastiff again!
He couldn't have imagined that Mastiff would appear at this time!
At this moment, Gu Er's heart sank to rock bottom.
He had experienced Mastiff's terror, but Zhang Fan's current strength?
Was it enough?
"Speed up, fastest pace!" Gu Er's voice sounded a bit anxious.
Nie Yi and his group were also terribly silent.
Gu Er had long told them about Mastiff.
Even with the strength of Nie Yi, Miao Da, and Ying Yun combined, they were no match for Gu Er.
Let alone Zhang Fan's strength, which was only comparable to theirs.
