After this time, the world was in a state of silence for a while, and each country was busy reconstructing the damaged properties.

Likewise, Martial City was severely damaged, and the officials were currently trying to best to restore the economic situation of Martial City as soon as possible.

For some people whose properties were damaged by the abyssal demons or in the fight between the abyssal demons, the government voluntarily compensated them fairly.

Yang Song spent several days absorbing the Spiritual Energy in the 20 A-rank Inner Cores.

When he stopped cultivating, he was overjoyed to find out that his cultivation base had advanced by leaps and bounds.

If it was before, Yang Song felt that he should need at least one month to advance to the 9th stage of the Foundation Building Realm. But now, he would only need a few more days at most.

At the moment, he had no more Inner Cores. Therefore, his priority was to get more Inner Cores.

After he broke through to the 9th stage of the Foundation Building Realm, Yang Song would visit the Black Wolf Gang and search for information regarding the Zero Green District Base.

But that did not justify that he would really get clear information about the Zero Green District Base. Maybe the Black Wolf Gang did not know much about that organization at all, but it was still necessary to visit them.

Speaking of it this way, Yang Song became unsure when would he get to destroy this Zero Green District Base completely.

Yang Song waved his hands slightly and three huge corpses of the abyssal demons appeared in the spacious cave.

These three corpses were the corpses of the three great abyssal demons that appeared previously and were killed by the Innate Blood Demon Killing Formation's Blood Demon.

At that time, when the corpses of these three abyssal demons disappeared, people thought that it was like that because they died.

No one knew that the three corpses had actually been stored away by Yang Song instead.

After taking out these three abyssal demon corpses, Yang Song took a clear look at them and found that their bodies were unusually hard. However, this level of hardness was still considered weak in the face of the Blue Bolt Sword.

Since these guys were the boss-level abyssal demons, their Inner Cores should at least be A-rank.

But if it were to really be A-rank, then Yang Song would be quite disappointed. Now, Yang Song estimated that he would need around 30 A-rank Inner Cores more to complete the breakthrough.

There were only three abyssal demons here, which was equivalent to three A-rank Inner Cores.

But Yang Song obviously could not care that much now, it was fine even if there were only three Inner Cores.

With this thought in mind, Yang Song took out his Blue Bolt Sword and slashed the white fluffy ball-like abyssal demon.

The Blue Bolt Sword cut a straight vertical line on the body of this fluffy abyssal demon. Yang Song did not exert strength too much since he was afraid that he would accidentally damage the Inner Core.

Inky black blood flowed out frantically and dyed the white abyssal demon black.

For the abyssal beasts, their Inner Cores were in the middle of their brains, but after Yang Song inspected the head of this white abyssal demon, he found nothing.

Yang Song then shifted his gaze towards the chest of this abyssal demon and used his sword to rummage the internal organs of this demon.

Without seeing anything special here, he went further to the abdomen area. This time, as Yang Song stirred the internal organs with his sword, he suddenly bumped into something hard.

Yang Song quickly cleared up the way and finally found a colorful bead inside.

When he saw this thing, he was shocked and overjoyed.

He was overjoyed because he finally found an Inner Core, and he was shocked because… this Inner Core was unusually big.

It was many times bigger than the A-rank Inner Cores he had just used up in the morning.

If those A-rank Inner Cores were the size of a golf ball, then the one in front of him currently was as big as a bowling ball.

"Is this Inner Core above A-rank?" Yang Song speculated.

However, when Yang Song plunged his Spiritual Sense into this Inner Core and inspected the purity level of the Spiritual Energy inside, he was disappointed that, except for the size of this Inner Core and the amount of Spiritual Energy inside, the purity level was nothing new.

In other words, this Inner Core should still be in the range of A-rank. It was just that this Inner Core was roughly equivalent to 10 normal A-rank Inner Cores.

Yang Song shook his head slightly and put the Inner Core of the white abyssal demon aside, then he proceeded to take out the Inner Core of the next great abyssal demon and the one after that.

Soon, Yang Song put the abyssal demon corpses back into the storage space and gathered three bowling-sized A-rank Inner Cores, which was the same as having thirty normal A-rank Inner Cores.

With this, Yang Song was doomed to advance to the 9th stage of the Foundation Building Realm in a few days.

...

Four days later.

A loud bang resounded inside Yang Song's body and a sense of looseness appeared inside Yang Song's body.

Yang Song opened his eyes slowly and exhaled a gentle breath.

A stream of white mist flowed out of Yang Song's nostrils and lingered around him. The scene looked extremely ethereal as if this place was a place of the higher heaven where mystical existences resided in.

The white mist was nothing else but residual Spiritual Energy that Yang Song inhaled when he was cultivating.

At this moment, Yang Song couldn't help smiling.

He had successfully broken through to the 9th stage of the Foundation Building Realm, the very peak of the Foundation Building Realm itself.

The next breakthrough would be the Core Formation Realm.

At this time, Yang Song felt that his body was significantly different from before.

His original gray hair became mostly half gray and half black. His wrinkles also vanished a lot.

To sum it up, Yang Song's current true appearance was no different from a handsome middle-aged man. But who knew that this middle-aged man was 100 years old?

But Yang Song was used to his old appearance, so with a thought, his appearance changed and looked like before again.

Except for the changes on the surface, the changes inside his body were also not bad.

Now, his Dantian became much bigger and he could store more True Energy than before.

The overall quality of his True Energy also became much better. And not only that, his scope of Spiritual Sense also increased by 10.

Now, the area with 190 meters could not escape his perception at all.

In addition, his speed of drawing talismans also turned faster than before. And this had something to do with the improvement of the quality of his True Energy.

Last but not least…

Yang Song moved his thoughts and activated the Ten Thousand Returning Swords Art.

600 sword clones of the Blue Bolt Sword manifested in the cave and made the cave lit up in blue.

Yang Song nodded in satisfaction and put away the 600 sword clones.

Now, what he had to do next was drawing more talismans and visiting the Black Wolf Gang.

It took Yang Song another day to draw all the necessary talismans. After drawing, he simply life the White Dragon Abode and flew to Martial City with his sword.

After arriving at Martial City, Yang Song first went to Li Wanjing and inquired about the location of the Black Gang Paradise District.

After he got a clear understanding of it, he left without a word.

…

Black Gang Paradise District, Black Wolf Club.

As usual, the atmosphere in this place was noisy and full of the breath of disorder. The colorful light of this place was in complete contrast with its name.

A figure leisurely landed at the entrance of the Black Wolf Club, however, no one seemed to be able to see him or notice his presence at all.

This visitor was Yang Song, of course.

After landing, he entered the Black Wolf Club without any sense of discomfort at the sight of various unruly and unscrupulous actions inside.

Before coming, Yang Song only got to know the boss of this place, called Lang Ping, and this place's businesses.

As for the structure of this place, Yang Song did not need to know in advance at all because with his Spiritual Sense, it was as simple as drinking water if he wanted to explore this place.

After entering, Yang Song spread his Spiritual Sense and found that, indeed, there were secret rooms in this place and several hidden figures too.

When Yang Song spotted them, he was a bit surprised to find that they were not simple martial artists at all. All of them had psychic energy on them!
