As soon as Yoze activated Iron Skin his skin turned a light gray metallic color causing him to resemble an iron giant. His muscles seemed to hold a hidden power to be capable of defending against even the strongest weapons.
Taking a deep breath and exhaling a stream of hot steam Yoze activated his modified Blood Fist that pushed his body to its limits.
"Crack crack crack"
The sound of Yoze's body cracking from his body being forcefully expanded due to his blood boiling was even audible through his walls. If it wasn't for the fact that no one lived in any of the rooms near his except for Jewel and his father then he would have had to do some explaining.
Due to his body temperature reaching so high that he could cook an egg in his hands, the light gray metallic color on Yoze's skin began to be overwhelmed by a red hue. After ten minutes the resemblance of an Iron Giant was gone and he looked more like a burning giant or a pillar of red hot steel.
The temperature of his room grew so hot that the air twisted and the floor that was made out of extra-strong concrete began to melt.
"Yoze! What's going on?" Being alerted from his nap Leah woke up feeling as if he was inside a sauna.
"Don't worry about it, just training. I'm almost done." Yoze said calmly.
The intense pressure and heat that his body was generating were sending his Iron Skin body cultivation into overdrive. He was trying to create more Iron Skin Inner Vigor to increase the density of inner vigor in his skin.
This way the defense of his skin increases and if it went the same way as when he broke through Big Golem his control over Iron Skin Inner Vigor should increase.
After several minutes Leah looked at Yoze with horror on his face. He had just remembered why he didn't like hanging out with Yoze for too long since it was a danger just being around him.
Leah ran to the farthest corner away from Yoze and the coolest in the room and waited until Yoze was finished. Eventually, between his muscles and flesh new tough metallic Inner Vigor was squeezed out.
The moment this Iron Skin's metallic inner vigor was created all the metallic inner vigor in Yoze's body went into chaos. The gray color on Yoze's skin quickly faded and was replaced with his regular skin color.
Yoze didn't panic however and knew that he had made the correct step. He kept stressing his body and kept up his intense body temperature to keep creating more of Iron Skin's metallic inner vigor.
[Iron Skin (Level 3: 110%)]
With every strand of tough and metallic inner vigor, his body produced the remaining became more chaotic, and each strand increasingly crashed into every nook and cranny of his body with more and more violent force.
[Iron Skin (Level 3: 175%)]
Eventually, the amount of metallic inner vigor inside his body grew too much for the metallic inner vigor to handle and one strand of inner vigor entered his skin.
With a strand creating a path to solve this metallic inner vigor crisis the rest of the inner vigor followed suit. From one strand entering his skin to five strands entering his skin every second.
At such a fast pace of Iron Skin inner Vigor fusing with his skin, Yoze noticed that underneath his skin was a metallic shine. Even without the gray color following suit, he could tell that his skin was just as strong and able to defend against attacks as when he activated Iron Skin at full force.
[Iron Skin (Level 3: 190%)]
Soon the last strand of Iron Skin's metallic inner vigor fused with Yoze's skin but he knew that he wasn't finished yet. To reach the next level he needed to completely saturate his skin before he could replenish his storage.
So he kept up the heat and started the process to complete a Blood Fist. By the time Yoze reached halfway to completing the Blood Fist his arm began to swell. His arm nearly doubled in size and threatened to produce so much destructive force that it would destroy the entire Ten Ton Inn.
However, he wasn't worried about destroying the Inn since he never planned to complete the Blood Fist in the first place. He was merely using it to stimulate the production of Iron Skin's metallic inner vigor.
Just as he expected the pressure and the drastic increase in temperature inside his body ramped up the number of strands of metallic inner vigor his body produced by nearly triple the quantity.
It didn't take long before his skin was completely saturated with metallic inner vigor. Once the saturation process had been completed it meant that every new strand would become the inner vigor that he could activate to increase his defense.
[Iron Skin (Level 4: 5%)]
"See I told you it wouldn't take too long. I don't understand why I didn't just do this earlier. It took me less than two hours to take Iron Skin to the next level." Yoze turned around to face Leah who had hidden in a corner.
"Stay away from me, I don't want to accidentally be turned into burned meat." Leah shook his head and tried to turn Yoze away since he was making everything unbearably hot.
"Fine, but you are going to be staying with my Dad for the next few days to protect him and alert me if anyone attacks him." Yoze stopped in his tracks and said to Leah.
"Is it because of the people that are in the other corners of the room?"
"Either way, I was planning on staying with him since there is no way for me to rest in this hot room." Leah stood up before sitting back down when he noticed that the floor near Yoze was melting and decided to go to Drew's room later.
