Chapter 1645

The next morning, Su Xiao woke up very early. He checked his mana and it had recovered to 7,026 points. As his real intelligence attribute increased, his mana recovery speed was also increasing. Moreover, there was the bonus effect of Xiang Ignoring Bubu Wang's Ice Goddess Aura, which recovered an additional 5 mana points per minute.

After weighing it repeatedly, Su Xiao prepared to go and risk improving a certain ability. Because of the rapid increase in his strength, that ability was already somewhat unable to keep up with his pace.

If he improved this ability by normal means, there would indeed be no risk, but Su Xiao used unconventional methods. For the cost others paid to improve by 1 level, he could improve by 3 to 5 levels, or even many more.

Bringing along the 'mobile blue buff' Xiang Ignoring Bubu Wang, Su Xiao headed straight for the Skill Upgrade Hall. This shattered Xiang Ignoring Bubu Wang's thoughts of going out to play; improving that ability also required quite a bit of mana.

Soon, Su Xiao arrived at the Skill Upgrade Hall, familiar with the path, he came to the inner side of the Skill Upgrade Hall and found an unoccupied skill upgrade pod.

Pshhh~

Steam surged, the skill upgrade pod locked, and Xiang Ignoring Bubu Wang lay in the corner of the upgrade pod, starting to catch up on sleep.

【Please select the skill you need to improve.】

Su Xiao chose the 'Breath Release' ability because, due to a certain accident, he hadn't improved this very practical ability for a long time.

【Selection complete. To improve 'Breath Release lv. 18', you need to pay 50,000 Paradise Coins. Yes/No to pay.】

"Pay."

As soon as Su Xiao finished speaking, a sense of teleportation struck him. When his vision recovered, he was already in an ancient battlefield.

The ground was dark red, as if soaked in fresh blood. The corpse of a giant dragon lay prone on a low hill, holding a black heart in its mouth. Not far from it was a giant wearing red armor, with an empty chest.

The corpses of powerhouses from various races were scattered across the ancient battlefield. Because there were corpses of the Demon race, the ancient battlefield was filled with a sulfurous smell. Just smelling this scent made one feel dizzy and lightheaded.

Scarlet mist drifted across the ancient battlefield; this was the blood aura of countless powerhouses during their lifetimes. Perhaps even slaughtering a million living beings wouldn't produce such a dense blood aura.

Compared to a mere butcher, the blood aura of the ancient battlefield was more solid and purer. This was already a type of energy that could be used as a weapon. This place was once a prosperous place within the Void, and it was only after the decisive battle between the Law-Breakers and the spellcasters that this ancient battlefield was formed.

For the races of the Void, this was a forbidden zone. Something extremely 'crazy' once resided here, and even though that thing had now moved to the deepest part of the Black Abyss, no one was still willing to come here, except for some wandering treasure hunters.

Su Xiao had entered the Void, but he could return to Reincarnation Paradise at any time. This time, he was just here to improve his ability, not to carry out a mission in the Void.

As soon as Su Xiao appeared, the blood aura of the surrounding ancient battlefield surged toward him. These blood auras had extremely strong corrosive properties; once they invaded the human body, the consequences would be endless, unless one could return to Reincarnation Paradise as soon as possible.

The normal process for improving Breath Release should be for Su Xiao to use his own aura to resist the blood aura of the ancient battlefield, thereby training his own aura to achieve the effect of improving Breath Release.

And last time, Su Xiao's brainwave was amazing: he converted his mana into Qing Gang Ying energy, used Qing Gang Ying energy to form a 'temporary devour core' outside his body, and used the absorption of this devour core to purify and refine the blood aura of the ancient battlefield, thereby using it to improve the strength of his own aura.

In this way, it was the temporary devour core that was corroded by the blood aura of the ancient battlefield. Su Xiao only needed to deactivate this thing to prevent the blood aura of the ancient battlefield from invading his body.

Undoubtedly, Su Xiao's hypothesis was perfect, and after practice, this hypothesis was very successful. But who would have thought that last time, just as he was devouring the blood aura, a blood-colored giant hand suddenly appeared in the ancient battlefield.

This time, Su Xiao was prepared to stop while he was ahead, improving as much as he could. However, what he didn't know was that the owner of that blood-colored giant hand, that monster with white hair and a withered body, had already been casually crushed to death by the Blade Demon. In other words, as long as the Blade Demon didn't come, the ancient battlefield was no longer dangerous. As for the Blade Demon, he was currently in the deepest part of the Black Abyss, lying in the Life Flower Sea in a daze.

Blood aura surged around Su Xiao. His eyelids drooped; it was very difficult to resist the blood aura of the ancient battlefield with his own aura, and in the process of resisting, he also had to shape a simplified version of the devour core.

Light blue energy surged in Su Xiao's palm. Considering that the blood-colored giant hand might appear again at any time, he only converted 1,000 mana points into Qing Gang Ying energy to form a simplified version of the devour core.

A few minutes later, a simplified devour core appeared in Su Xiao's hand. An energy line as thick as a little finger linked the simplified devour core and Su Xiao. Don't underestimate this energy line; this thing contained fifteen ultra-simplified small devour cores. Su Xiao's devour core had already had its upper limit increased once, and after resolving the hidden danger of the Blade Demon's energy, he could fully manipulate the devour core within his body without any usage restrictions.

The simplified devour core floated above Su Xiao. He took a deep breath, and the dozens of small holes on the simplified devour core opened, instantly sucking the blood aura of the ancient battlefield within thirty meters around him into it like a long whale drinking water.

Crack crack crack...

Cracks gradually appeared on the simplified devour core. Su Xiao wasn't surprised; this thing could only be used temporarily, and it was precisely because of this that it was safe, so as to avoid Su Xiao being corroded by the unrefined blood aura of the ancient battlefield, leading to mental confusion.

After a large amount of blood aura was sucked into the simplified devour core, the simplified devour core began to operate, purifying and refining these blood auras.

Soon, a pale red energy surged out from within the simplified devour core. At this time, the simplified devour core was already blood-red, full of blood aura impurities.

The pure blood aura was transmitted to Su Xiao along the energy line. The fifteen even more simplified devour cores within the energy line began to operate, purifying this blood aura time and time again.

In the end, the blood aura had been purified to be almost transparent, with only a faint red color visible.

The blood aura, purified sixteen times, merged into Su Xiao's aura, and his aura began to grow rapidly.

The reason why Su Xiao had a dense blood aura on him was not because he killed too many people; that was only a small part of the reason. Except for battlefield-type worlds, his number of kills in other worlds was limited. The reason he had such a heavy blood aura on him was entirely because he had devoured the blood aura of the ancient battlefield.

Last time, after Su Xiao absorbed the blood aura in the ancient battlefield, his aura was terrifying. This was also the main reason why his charm attribute couldn't exert its effect.

After the stabilization of multiple worlds, the blood aura on Su Xiao had gradually faded. Perhaps after a few more worlds, the blood aura on him that made people shudder would dissipate. But now he had come to the ancient battlefield to absorb blood aura again, which brought the blood aura on him to a new height.

Perhaps when his blood aura was strong to a certain extent, using Breath Release could even achieve the effect of Conqueror's Haki. Of course, this required a very high level of Breath Release.

Su Xiao sat cross-legged on the dark red soil. He sensed that his own aura was increasing at an exaggerated speed, and above him, due to the adsorption of the simplified devour core, a blood-colored vortex had already appeared.

Su Xiao was not addicted to the rapid increase of his aura; he always remained vigilant. Once the situation was wrong, he would immediately let the blood aura of the ancient battlefield corrode him, thereby triggering the teleportation mechanism.

However, Su Xiao absorbed blood aura in the ancient battlefield for a full ten minutes, and no abnormalities appeared around him.

With a 'crack' sound, the simplified devour core shattered, and the blood aura vortex enveloped Su Xiao. He was instantly teleported back to the skill upgrade pod.

With a miserable shriek, Xiang Ignoring Bubu Wang was startled awake. The fur on its back stood up, and its hind legs trembled uncontrollably.

In front of Xiang Ignoring Bubu Wang, Su Xiao, with red patterns all over his face and blood-red eyes, was looking at Xiang Ignoring Bubu Wang.
