?His Mind's Eye was where his soul qi was stored. Over time, it had evolved from a world of golden fog to one filled with a thick ocean of what looked like melted gold.

With the exception of when Dyon activated his halo, his soul didn't have bottlenecks like what his qi did with his meridians. However, this was because he directly expelled his qi from his Mind's Eye, to his surroundings, and only then manipulated it into the technique or array he wanted.

It was impossible to do this with normal qi because it wasn't as pure. In addition, qi techniques required very specific circulations within the body. If it was expelled first, it would be very crude. This was because, once again, normal qi was not as pure and as such could not communicate with the heavens as easily as soul qi could.

'Wait my halo.'

Dyon's mind grinded to a halt as he finally found a solution. He kept thinking about increasing the volume of his meridians and blood vessels. But, why not focus on increasing its surface area simultaneously?

The square cube law only applied if the same shape was maintained while size increased. But, what if Dyon didn't bother maintaining the same generic tube shapes of his meridians and blood vessels?

When Dyon managed to reach this line of thought, he acted immediately, thanking his soul halo.

He had managed to reach this conclusion in a rather roundabout way. When Dyon formed his soul halo, was he not pouring soul qi into his brain? Why was it that his people's minds could withstand soul qi, but if other species attempted, they would be essentially committing suicide?

Dyon remembered how panicked he became when his little girl poured her soul qi into her mind for the first time. He had never been so scared in his life.

It was only after he calmed down and investigated that he understood. The folds in the brains of his mortal people were far beyond that of normal humans and even the Sapientia Clan. As a result, their ability to withstand on hold qi in their minds was at an unprecedented level!

If Dyon thickened the walls of his meridians and blood vessels, widened their passageways, and manipulated their shape to increase their surface area by several fold

The results would be beyond his wildest imaginations!

Dyon didn't hesitate. Taking inspiration from the folds of his brain and even some from his digestive tract, he remolded his meridians and blood vessels from the ground up.

By the end of it all, he had only widened the passageways of both by about ten times, reaching a single centimeter. But, the space within was as if he had expanded them to ten centimeters instead.

These matters only took a short time to describe, but it took Dyon another ten years just to lay this proper foundation down.

At the moment, where his and Junior's bodies once stood, there were only a beautiful mesh of shimmering diamond meridians and blood vessels.

In addition to maximizing their surface area and volume, in the middle, near where Dyon's belly button would be, there was a deep red ruby-like structure. With a single glance, any expert could tell you that it was a dantian.

Dantians were an existence only Immortals had. However, Dyon had technically had one for a very long time thanks to his Inner World. In fact, his Inner World was far more functionally useful in comparison to a normal dantian.

However, Dyon didn't simply want to disregard his dantian entirely. Since he was so close to perfecting his mortal body, unlocking his dantian was as easy as breathing.

Still, he wouldn't do something as useless as using it for his qi. There was simply no point. However Why not give his dantian over to his blood vessels? Since vital qi was so limited without ability to evolve or come from the atmosphere, this was the best method Dyon could think of to fully maximize its power.

Like this, Dyon gained two dantians. One with his Inner World, and another for his body cultivation!

By this point, Dyon was finally content with this layered foundation and moved onward, starting to build up his skeleton.

The motes of light from Junior's Death God Body surged building up Dyon's now deep black bones.

Dyon didn't want to change much about his new skeleton structure and didn't particularly care that it was now black. It wouldn't shine through to the surface regardless. In addition, these bones were already perfected to the pinnacle of the mortal limits of Death God Body.

However, Dyon did want to make a small shift.

Combining his Eternity's Balance constitution's ability to equilibrate and his Silver Mirror Constitution's reflective abilities, Dyon extended his defensive abilities from just his qi.

Now, any strike that managed to land on his body was disperse through his whole skeleton. In addition, it would be reflected back by a certain percentage depending on its power. Like this, the Death God's skeleton's defense prowess raised by several folds.

Like this, a skeleton of black, standing at almost 6'10, manifested itself. The beautiful structure of meridians and blood vessels penetrated deeply within it, the rest of the mesh network hanging like a gorgeous work of art from its frame.

The colors of black, red and diamond looked particularly enticing.

With that, yet another 10 years passed.

Dyon then turned his attention to his flesh. Organs were always the most sensitive part of the body. They simply couldn't be freely turned into diamond or tough flesh as easily both because of their sensitivity and the fact they wouldn't function properly if their properties were changed too much.

The best body refinement techniques could account for both factors, changing the function of organs such that they wouldn't miss a step. This was something Dyon now had to consider for himself.

In the end, he decided on a few things.

Firstly, he increased the robustness of his digestive system. From their normal smooth muscles, he replaced them with strong, robust muscles.

[Author Notes: The short of it is that smooth muscles function with conscious action of a person. You can't tell your digestive system to digest with your mind, for example]
