Hamar continued using his sound technique, echolocation. In the dark inside of the fleshy mutated body, he would clap and use the sound waves reflecting to orient himself.
Using the technique, he travelled up through the oesophagus and changing pathways into the lungs. At this scale the lungs were like a thick brush which Hamar could easily squeeze through.
As he travelled through the lungs into the body cavity, he could slowly see a violet light grow. As he broke through and fell through into the body cavity, he came to see the source of the light unobscured.
"Is th-" he stopped suddenly as his ear popped and a crackle picked up. Then it hissed and he heard a voice.
"Are you fine? I've recovered enough to create this line of communication."
Hamar touched his temple, "...yeah, I'm fine. Actually..."
"...hm?"
"I think I found the living core, it looks like a violet crystal and..."
"And what?"
Hamar stood up and sloshed around a small pool of blood before he touched the core he had found. It was a large violet crystal about the size of two men. He reached out his hand and felt the cold surface.
"And I think it's some sort of mutated Spirit Stone, it's violet and pulsating lightly with a violet light."
"A Spirit Stone...that's weird."
"Weird, how?" Hamar walked in a circle around the crystal observing it pulsate light.
"Without proper extraction, especially how he died, the Spirit Stone Soul should've been destroyed rather than turn into a Spirit Stone..."
Hamar remained silent and put his hand onto the stone calmly. He closed his eyes and recalled his lessons in the Nine Clouds Sovereign Sect.
'It doesn't reject me?'
"Hypothetically, how would you absorb a Spirit Stone?"
"No, whatever you're thinking, stop. You don't know whether that's safe! You said it's mutated, perhaps it's dangerous!"
"Just, tell me."
Yan sighed back on the surface. Just leant back and looked around before whispering. She excited the common way to absorb Spirit Stone, and what should happen.
"But again, think about what if anything goes wrong."
"I will-" Hamar used a small amount of aura to break the connection. He looked down at his body and felt the injuries, 'I should be recovered enough'
He took a deep breath then sat down, only has neck sat above the blood. He was completely covered. Then he placed both his palms onto the mutated Spirit Stone.
"If I'm right, then this should help me progress my next body reformation. Yi Sect is almost definitely connected for sure now."
Hamar recalled the last time he touched a Spirit Stone. Just basic contact would cause a reaction and he would feel it reject him. This Spirit Stone however accepted him.
"It must be something to do with Yi Sect! Both I and them have connections to the outside world. I follow a technique from the outer world and they wish to join that world...they must've been researching ways to escape the world's control"
Hamar could sense his increased mental capacity as he let go of using mental energy to absorb mana to increase aura to heal himself. Now he could use that mental energy for use in thinking.
"I must get stronger and if that means taking advantage of Yi Sect then that's even better!"
He started using his mental energy and injecting it into the Spirit Stone. At the same time, he used thread of aura to reinforce it.
Inside the Spirit Stone, he could feel a complex pattern. He carefully explored it, conquering the stone slowly.
After a few moments he had to stop and recover, meditating for a moment and continuing. Each time he left to regain his mental energy he would lose some footing in the Spirit Stone conquering.
It was a slow battle of forces. Eventually, above ground the sun set and rose again. A day passed as Yan continued to recover slowly and Hamar fought his battle to absorb the Spirit Stone.
Finally, after another half-day, he gained superficial control over the main Spirit Stone. For the next step, he tried to move the stone's material into his body. However as he did, something awoke.
From the very centre of the Spirit Stone. The remnant souls of the mortal victims of Zhangfu spread forward and submitted to Hamar. They recognised him as their avenger, allowing them to beat Zhangfu's soul and consciousness once he was left within the Spirit Stone.
These remnant souls used their final bits of power to carry the Spirit Stone into Hamar's body and assimilate the two.
They were mortals but after being absorbed into the special mutated Spirit Stone, they gained a special knowledge.
They had a basic knowledge of forming a physique, however when that knowledge combined with Hamar's own body and techniques they created something new.
Hamar quickly meditated and helped the remnant souls absorb the stone material into his bones. As he did, his Royal technique resonated and he gained an intuitive knowledge of what had occurred.
'They tried to give me the same physique as that man...Zhangfu. It would give me an intuitive look into Yin and Yang but after resonating with my body and techniques, all the downside have disappeared.'
He breathed roughly and the Spirit Stone in front of him shrank quickly, turning into a pin drop before shattering.
'Though the upsides shrunk as the downside disappeared too. Now I sense that when I use my golden aura inside these bones, I should be able to enter a powerful state'
Hamar held out his palm, "In that state, I should be able to reverse any law. It's an upgrade to my previous techniques where I took control of laws and shifted them." He balled his hand into a fist and smiled.
The Spirit Stone was fully absorbed and now he had gone through half a body transformation. His bones were now a form of Reversal crystal that contains profound Yin and Yang capabilities.
