A series of prompts sounded, and Tatsuma increased his equip slots from 27 to 50.
With the number of equip slots nearly doubled, Tatsuma equipped more traits. Although it didn't double his strength, the increase in Training effect was maximized.
Affected by the training traits, the effects of Senjutsu and hōgyoku, which were developing his potential, were greatly enhanced. Like switching to nuclear power, the speed at which Senjutsu and hōgyoku developed his potential increased by nearly a hundred times.
Endless potential was being developed, and the thumping sounds echoed like an engine.
His skin, tendons, muscles, and bones were tempered, and [God of Devils and Dragons] was affected, erupting with even more surging energy.
A series of chain reactions were triggered, and Tatsuma felt his mind become clear, in a state better than ever before.
"This is an unexpected pleasant surprise." A thoughtful look appeared on Tatsuma's face.
The number of equippable traits greatly increased, and the training amplification multiplier stacked to an exaggerated degree.
Affected by this, traits like Hōgyoku, which could help with idle training, saw a significant increase in cost-effectiveness.
[Trait advancement successful, congratulations on obtaining the Rainbow trait: Hōgyoku.]
[Hōgyoku (Rainbow): Greatly increases the host's immortality, and fulfills the host's or target's wish under the right conditions.]
[Trait advancement successful, congratulations on obtaining the Rainbow trait: Senjutsu.]
[Senjutsu (Rainbow): A technique that manipulates Ki and natural energy. After deep development, it can explore the essence of the world and be used in many fields.]
Two consecutive prompts sounded.
Tatsuma consumed twenty Gold traits, upgrading the Hōgyoku and Senjutsu traits to the Rainbow level.
Compared to before the upgrade, the descriptions of these two traits didn't change much, but their original effects received a huge amplification.
Coupled with the training amplification from other traits, Tatsuma's idle training effect further accelerated. Basically, every minute and every second, his aura would be enhanced, profound and terrifying.
"Feels a bit too fast."
Tatsuma focused on the power within his body.
Getting stronger was a good thing for him, but there were still some things that needed attention.
For example... control over power.
With Limitless Potential, Tatsuma's control over his own power was almost perfect. However, this time the improvement was simply too great.
Especially the Senjutsu and Hōgyoku traits, after being upgraded to the Rainbow level, they began to transform his body.
This wasn't a temporary enhancement dependent on the trait itself, which would be lost if the trait was unequipped. Instead, it was a more fundamental, permanent transformation.
Turning his current stage of strength into a progress bar, Tatsuma's original improvement was 0.1, 0.2, 0.3...
Not fast, not slow, but very stable.
But now, his improvement progress was 1, 2, 4, 7, 13...
Not only astonishingly fast, but also very unstable.
Of course, the process of enhancement was controllable. As long as Tatsuma was willing, he could stop this enhancement at any time, or even restore his body to its initial state.
However, after careful observation, Tatsuma found that the enhancement from Hōgyoku and Senjutsu was not harmful. On the contrary, these two traits were enhancing his life essence, allowing his life essence, which had received the Indestructible amplification, to be further improved.
With such a good thing, Tatsuma naturally wouldn't refuse.
Raising his hand to set up a Time Barrier around him, while adapting to the new power within his body, he manually accelerated the speed of evolution.
Sun rose and moon set, time flowed, and in the blink of an eye, half a month passed in the outside world.
Under the acceleration of the Time Barrier, Tatsuma spent over forty days, finally ending his evolution.
Coming back to his senses from the depths of his consciousness, the aura on Tatsuma's body gradually became stable.
Amplified by numerous traits, his idle training effect was still as fast as it was half a month ago.
But after his life essence was amplified, his understanding and control of power further improved, and the phenomenon of aura leakage due to excessive improvement no longer occurred.
However, compared to the many effects brought about by the evolution of his life essence, Tatsuma was currently more focused on another matter.
[Ding! Host's strength has broken through to Level 6, unlocking a new function: Black traits!]
The improvement brought by the life leap was all-around.
With continuous training on a daily basis, Tatsuma's physical quality in his normal state had already approached a breakthrough.
This time, by further evolving his life essence, he finally broke through the bottleneck and entered the Level 6 domain.
Opening the trait panel, Tatsuma checked the new function.
[Black traits: Increases the upper limit of trait quality. Rainbow traits can be upgraded to Black traits. The materials consumed for upgrading to Black traits depend on the strength of the trait itself.]
As Tatsuma had guessed before, Black traits required a certain level of strength to be unlocked.
This time, with his basic strength breaking through to Level 6, he successfully unlocked the upgrade permission and could further upgrade [God of Devils and Dragons] and other Rainbow traits.
However...
The materials consumed depend on the strength of the trait itself. Does this mean the amount of materials needed to upgrade a Rainbow trait to a Black trait is not fixed?
Looking at the last sentence of the new function, Tatsuma thought for a moment and then opened the trait upgrade function, dragging the newly upgraded Hōgyoku trait onto it.
[Upgrading Hōgyoku to the Black level requires consuming ten Rainbow traits. Do you wish to upgrade?]
No.
Tatsuma removed the Hōgyoku trait and replaced it with other Rainbow traits for testing.
[Upgrading Limitless Potential to the Black level requires consuming thirty Rainbow traits. Do you wish to upgrade?]
[Upgrading Origin Fruit to the Black level requires consuming fourteen Rainbow traits. Do you wish to upgrade?]
[Upgrading Indestructible to the Black level requires consuming sixteen Rainbow traits. Do you wish to upgrade?]
A series of prompts sounded, and Tatsuma quickly tested all the Rainbow traits in his arsenal.
Compared to before, upgrading Rainbow traits mostly required over a dozen materials of the same level.
Rainbow traits with wide application and powerful effects like Limitless Potential even required thirty Rainbow traits as materials, an astonishing amount.
'The number of materials needed to upgrade Rainbow traits is not fixed, but no matter how strong the effect of a Rainbow trait is, it only counts as one material unit. This is really dark.'
Tatsuma shook his head slightly, feeling a bit helpless.
This trait panel was definitely making a profit on the difference.
Temporarily giving up on the idea of upgrading Limitless Potential, Tatsuma dragged [God of Devils and Dragons] into the upgrade slot.
Through the trait fusion function, due to fusing two Rainbow traits, [God of Devils and Dragons] only required five Rainbow traits to be upgraded.
After unlocking the equip slots and upgrading the Hōgyoku and Senjutsu traits earlier, Tatsuma still had 100 Gold traits in his hand that could be used as materials.
Taking out 55 Gold traits for fusion and upgrade, Tatsuma sacrificed the fused materials.
[Trait advancement successful, congratulations on obtaining the Black trait: God of Devils and Dragons.]
Boom!!!
Accompanying the prompt sound, a deafening roar also came.
A violent force surged from within Tatsuma's body, and the ground beneath his feet collapsed and caved in.
A terrifying aura permeated from within his body, affecting the entire Akatsuki and even the surrounding areas.
Within a radius of ten thousand miles, all sounds disappeared.
As if being stared at by some terrifying monster, whether human or animal, they instinctively held their breath.
But at this moment, Time energy swept through. Time in the surrounding area flowed back one second, and everyone, whether ordinary people on the streets or members of the Akatsuki, completely forgot the recent events in their minds.
