This Black Iron Shield was a treasure he found early on while traveling in the Longyuan World.
However, its function is quite singular, with only a protective ability.
It cannot channel Star Power or Soul Power, but when it comes to defense, it is truly the top protective treasure the black shark had seen in tens of thousands of years.
No matter what kind of attack, it cannot break this shield.
Just now when facing Lu Lin's attack, he actually didn't even think of using this shield.
Lu Lin naturally also saw that his attack did not cause any damage to the shield, and couldn't help but let out a slight exclamation.
"Lu Lin, wait."
The black shark shouted loudly, "You are heading to the Longyuan World next. I have twelve secret bases there. If you spare my life, you can take any of my treasures after arriving in Longyuan World, how about it?"
The black shark didn't believe it. Even if Lu Lin didn't care about humans, he couldn't be indifferent to treasures.
