The changes to his body.

The pain started out as a slight prickling sensation, but it quickly magnified, turning into a torrent of lava that surged throughout all of Yao Jun's body. He lost all control over his body, slumping down onto the ground and curling up into a trembling ball.

Before Yun Yantian could step forward, a white light seeped out from Yao Jun's chest, quickly covering his entire body in a cocoon of light. The cocoon didn't just cover Yao Jun, it also expanded to cover Little Gray and Little Thunder, obscuring their bodies and preventing Yun Yantian from seeing anything.

"Why does it have to be so abnormal? Isn't it just reaching the first level?"

Yun Yantian muttered to himself as he tried touching the cocoon of light that was covering Yao Jun and his pets, but the light sent out a strange type of energy that pushed his hands away. Since he couldn't touch the cocoon or even see through it, he had no choice but to sit down next to it, standing guard for Yao Jun.

Inside the cocoon, Yao Jun felt like he had dropped into the deepest pits of hell. Energy coursed throughout his entire body, constantly baptizing and strengthening his entire body. The energy felt like molten lava coursing through him. He wanted to scream and cry out, but he felt like something was pushing down on his chest, preventing him from even breathing properly.

The pain was especially bad around his heart and head. His eyes felt like they were being plucked out and sown back into his eye sockets repeatedly. If someone could see his situation, they would see that his eyes were completely red, blood dripping down from the corners.

"Ahhh, once more we return to the world, to reign supreme and eternal."

As Yao Jun was suffering through the pain, an ancient and dreary voice rang out in his mind sounding out with a loud sigh, but before he could find out where the voice came from or ask any questions, the voice faded away.

After the pain around his heart and head started fading and Yao Jun thought he was reaching the end, his forearms and back started burning with the same pain. Blood seeping out from his skin and dripping down onto the ground. When the blood hit the ground, it flashed with purple lightning before suddenly vanishing, not even leaving behind a mark on the ground.

While Yao Jun was enduring the pain within the cocoon, a strange aura started seeping out from his body and into the world around him. The first one to notice this aura was Yun Yantian. The aura was tyrannical and mighty, seeping into his very bones and filling him with a sense of awe.

Yun Yantian was shocked at this aura, but what he didn't know was that the Demonic beasts located within the forest around him had all stopped whatever they were doing, shivering and trembling beneath this aura.

The pain continued coursing through Yao Jun's body for almost an entire hour before he was finally released from its grasp. He wearily opened his eyes and found himself lying on his back, his entire body drenched in sweat.

As he looked up at the sky, he noticed that his vision had increased greatly. He slowly turned his head, looking into the forest not far from him. He was shocked that he could see much further into the forest like the trees weren't even there. Without putting any energy into his eyes, he could already see to a distance of 25 kilometers. If he circulated some Qi into his eyes, the range would increase to 50 kilometers.

Yao Jun couldn't help but exclaim out loud. This was much more than just a great increase in vision, this was on an entirely new level. Despite how dark the forest ahead of him was, he could see everything as if it was in the middle of the day. If it was within 10 kilometers, he could even count the legs on the bugs he saw. If his vision was like this, his survivability would greatly increase, allowing him to see many threats before they could even spot him.

"You finally decided to wake up."

While Yao Jun was immersed in the experience of his increased vision, Yun Yantian's relieved sigh came from his left. Yao Jun slowly sat up and turned his head, his eyes falling on Yun Yantian. As he looked at Yun Yantian, he was shocked once more.

As he looked at Yun Yantian, the clothing on Yun Yantian's body slowly turned transparent. After his clothing vanished, so too did his skin, giving Yao Jun free sight into the inner workings of his body. Yao Jun could see a glossy metallic energy coursing through Yun Yantian's body, permeating every inch of him. The source of this metallic energy was a small sword that floated above his heart.

Yao Jun didn't need to think too much to know what this was, this energy was the Qi within Yun Yantian's body. And the floating sword was the source of Yun Yantian's power, his inborn power.

Yao Jun was shocked to discover that his eyes had been strengthened to such a degree, even allowing him to look at the inner workings of a person's body. As he kept looking, he suddenly felt a stabbing pain in his eyes. He quickly closed his eyes and stopped circulating Qi into them.

When he opened his eyes again, he could no longer see into Yun Yantian's body, it seemed like he had to pour Qi into his eyes to see into peoples bodies. Yao Jun didn't mind this too much, if he was constantly looking into peoples bodies, it would be easy for him to just see everyone as bones and piles of flesh.

While Yao Jun was looking at Yun Yantian with a shocked expression, Yun Yantian was also looking at him with a shocked expression. After emerging from the light cocoon, Yao Jun had several changes.

The changes Yun Yantian immediately noticed was that Yao Jun's once pitch black hair now had several dark purple strips, looking like lightning bolts in the night. On his back was a piece of crystalline gray armor, two wings engraved where his shoulder blades were.

Two crystalline purple gauntlets decorated his forearms. The gauntlets covered his entire forearm, even his hands. The tips of the gauntlets were pointed and sharp, looking like claws. There were small black lines that meandered around the gauntlet, giving them a fearsome appearance.

But the change that shocked Yun Yantian the most was Yao Jun's eyes. Yao Jun used to have pitch black eyes that shimmered in the light, looking like two gems in the night. But his eyes had suddenly changed, becoming a shade of gray that seemed to drag at Yun Yantian's consciousness, giving Yao Jun a mysterious charm.

When Yao Jun looked at Yun Yantian, Yun Yantian felt like all his secrets had been laid bare before him. He had seen people advance to the first grade before, he had even seen people advance to the second and third grade before. But he had never seen anything change as much as Yao Jun had.
