"An artifact capable of breaking formations?"
Lu Ren was startled. "Immortal-Smiting Iron, do you have any ideas?"
"Heh heh, of course I do!"
Two illusory hands appeared around Immortal-Smiting Iron's body and patted it, producing dull metallic clangs. "They set up an Eleven Heavens Killing Formation, didn't they? I, Old Iron, can stack another thirty-six layers on top of the original! I want to see what damned artifact can break my Thirty-Six Heavens Killing Formation!"
"A thirty-six-layer killing formation?"
Lu Ren's face changed dramatically.
This Immortal-Smiting Iron was far too terrifying. It had directly stacked thirty-six layers onto the eleven-layer formation.
"Thirty-six layers is nothing. If you weren't lacking materials, I, Old Iron, could stack forty-eight layers!"
Immortal-Smiting Iron continued laughing.
However, a trace of gravity flashed through Lu Ren's eyes. "But we only have one month!"
"One month is plenty!"
Immortal-Smiting Iron snorted. "For me, that's more than enough!"
A sharp glint flashed through Lu Ren's eyes. "Hahahaha, fine. Whatever materials you need, I'll give you!"
Immediately, Lu Ren handed all the materials he had for setting up large formations to Immortal-Smiting Iron.
Immortal-Smiting Iron lifted the materials with both hands and flew toward the distant mountain peaks.
Lu Ren did not hesitate either. He silently returned to the Cave Mansion.
"If Thousand Leaf Sin King truly wants to deal with me, she will definitely devise a foolproof plan to kill me in one strike, leaving me no chance to escape. So Hellfire Sin King will surely play along and enter the First Heaven!"
Lu Ren began making his calculations in secret.
However, once Immortal-Smiting Iron finished setting up the Thirty-Six Heavens Killing Formation and restrained Hellfire Sin King, severely wounding him, Lu Ren would not take anyone else seriously—even if they all attacked him together.
A month passed
