Five hundred kilometers is also the limit that the secret forces can block.

Lin Yu ordered his secret service brothers to do their utmost to contain the flying corpses within a 500-kilometer radius.

He then began to set up a formation along this encirclement.

This formation took two whole days and two nights to set up!

Lin Yu was almost exhausted, but thankfully, the formation was finally completed!

"Young Marshal, what is the purpose of this formation?" Feng Jiu asked with a surprised look.

Lin Yu glanced at him and said, "This formation has two functions. One is to seal off the spiritual energy of heaven and earth. When it has exhausted the spiritual energy of heaven and earth within a radius of 500 kilometers, it will not be able to obtain new oxygen, which will inhibit its growth rate! The second is that this formation will gradually shrink over time. When it shrinks to a small enough area, it will be easy to go in and capture it!"

Feng Jiu's eyes lit up, and she gave a thumbs up, saying, "Young Marshal, this formation is amazing! It's truly incredible!"

Lin Yu nodded and glanced down at his groin. "How are you? Does it still hurt?"

Feng Jiu's expression twitched slightly. "It's just that walking feels a little awkward!"

Lin Yu nodded. "That's normal. You're just talking like an ordinary person. You took too big a step and hurt yourself! You'll have to take good care of yourself from now on! Otherwise, you might lose your fertility!"

"Huh? It's that serious?" Feng Jiu panicked immediately.

Before he could say anything, Lin Yu had already turned and walked out of the woods.

"Young Marshal, where are you going?"

"I've heard that all the girls in Harbin have long legs. Come on, I'll take you to see them tonight!"

"Aren't you supposed to take good care of yourself?" Feng Jiu asked, somewhat puzzled.

Lin Yu's lips curled slightly. "Haven't you heard of the saying 'use it or lose it'?"
