Yang Song was cultivating in the White Dragon Abode as usual.

As morning came, Yang Song opened his eyes slowly and let out a long breath.

"It's still far from there," Yang Song then muttered.

It had already been a few days since the abyssal demons' incident, and he had been cultivating in the White Dragon Abode nonstop. However, he still had not been able to break through to the 8th stage of the Foundation Building Realm.

Yang Song felt that this problem had something to do with the purity of the Spiritual Energy between heaven and earth.

Thinking of this, he decided to ask the system, "System, why is my cultivation so slow even with such a high talent in cultivation?"

[As the Host thought, there is a problem with the Spiritual Energy of this world. After the detection, the system found that the Spiritual Energy between heaven and earth at the moment is actually the residual Spiritual Energy of several eras before. Therefore, the purity of the current Spiritual Energy is not so high.]

Hearing this, Yang Song frowned and asked, "So based on your words, it means that there were also immortal cultivators on the Blue Star several eras before?"

But the system stayed silent as if it did not hear Yang Song's question.

Yang Song was used to the system's cold attitude and guessed by himself instead. There should be immortal cultivators on the Blue Star several eras before, but they disappeared somehow.

Yang Song was not sure about the specific time of one era, but based on his knowledge, although an era was a span of time defined for the purposes of chronology or historiography, it should still be extremely long for an era.

So after a rough estimation, several eras should be equivalent to tens of thousands of years or possibly hundreds of thousands or even millions.

After such a long time, it was understandable that the Spiritual Energy became impure.

But there was one thing that Yang Song did not understand.

That was, based on the Immortal Cultivation Secret Manual, Spiritual Energy actually came from the void and was absorbed by the Spirit Vein of the planet. After that, the Spirit Vein would feed the planet back with the Spiritual Energy that it had absorbed.

This process was actually like an instinct of the planet.

The Spiritual Energy that came from the void was not pure Spiritual Energy, it was in fact a type of energy called "Chaos Energy". After the Spirit Vein of the planet absorbed the Chaos Energy, it refined the Chaos Energy and turned it into the Spiritual Energy.

Actually, there were also grades for Spirit Vein on each planet. The higher the grade of the Spirit Vein was, the purer the Spiritual Energy would become after the refinement.

Hence, it also made Spiritual Energy have grades too.

So now, since the Spiritual Energy of the Blue Star was not so pure, did it mean that the Spirit Vein of the Blue Star was low in grade or what?

But Yang Song had a hunch that it did not have anything to do with the grade, but the Spirit Vein itself was damaged…

Why did he say this? Simple, because in Yang Song's estimation, there should be many cultivators and other mystic beings in the past, so since such a world could give birth to so many supernatural beings, was the Spirit Vein low in grade?

No, on the contrary, the Spirit Vein of the Blue Star should be a good one.

But why did Yang Song dare to say that there should be many supernatural beings in the past?

It was also simple.

Yang Song was originally a writer when he was young. Since it was so, it was natural that he had done a lot of research regarding the mythology of this world.

Therefore, with that research, Yang Song found that there were so many supernatural beings in the past and this world also had a lot of similarities with the Earth.

To some extent, Yang Song guessed that this Blue Star was a copy of the original Earth. The only difference was that this world had real supernatural beings; he himself was a prime example.

So after the Spirit Vein was damaged, the supernatural beings of the past left the Blue Star or they went into hiding?

Speaking of supernatural beings, Yang Song also met a few in the abyssal demon incident a few days ago – the mages and ability users.

The Wind Master was a public figure and Yang Song had seen the other party on the news in the past. However, it was the first time that Yang Song had seen mages.

Mages, they were mystic beings who could command various elements.

As for ability users, they were not just limited to that. Ability users were like mutated humans who gained strange abilities.

Just like the group of people Yang Song had met in the White Mountain forest not long ago. One of them could smell like a dog, one of them could detect the breath of any human.

And the Zero Green District Base also had ability users. They could control fire, detect soundwaves, control the earth, blend in with the surrounding, and so on.

However, the abilities of ability users generally came with a fixed grade. Hence, it was hard for ability users to upgrade their strength.

As for mages, they had manuals and scrolls to practice just like the cultivation of the immortals.

But overall, in the current world, martial artists occupied the majority, and what came after that were ability users, mages, witches, etc., and immortal cultivators should be in the last place.

After a sigh, Yang Song shook his head and expressed that he did know what to do with his slow cultivation helplessly.

But it was not like there were completely no solutions.

That was… he could complete the tasks issued by the system and get the rewards. Not the recent task of unifying the whole world issued by the system a few days ago, but the task of becoming the number one family in Martial City.

Previously, when he had just conquered the Li Family, it allowed his family to jump to the 100th position among all the families in Martial City.

Now, after dozens of days, the Yang Family's ranking in Martial City was already in the 67th position.

So Yang Song thought of conquering other families and other forces in Martial City

With this thought in mind, Yang Song started drawing his plans right away.

…

Night, Martial City, Li Family's mansion.

A white-haired figure flew over with his sword calmly.

The person who came was naturally Yang Song.

Compared to the calm Yang Song, Li Wanjing and his subordinates were frightened when Yang Song came so suddenly.

But quickly they recovered their calmness and went over to greet Yang Song enthusiastically.

They bowed to Yang Song and Li Wanjing took the initiative to say, "Master, what can I do for you?"

Looking at the cautious Li Wanjing, Yang Song was quite satisfied with him. When he conquered this guy not long ago, Yang Song could also see through his mind. He knew that this Li Wanjing wanted to serve him well so that he could get those mystical rewards from him.

After that time, Yang Song deliberately ignored him and tried to see what he would do afterward.

He indeed did not fail to impress Yang Song. After that day, the Li Family actively supported the Yang Family unconditionally. Now, the Yang Family also had a base in Martial City.

What's more, with the help of the Li Family, the process of building the base here went smoothly without any troubles.

So finally today, Yang Song decided to put the Li Family into use.

Yang Song beckoned to Li Wanjing, "Let's go inside first and talk."

Li Wanjing immediately led Yang Song to the secret room in the mansion.

After sitting down on the main position, Yang Song took a cup of tea and slowly said, "I plan to conquer all the families in Martial City, and I need your help."

Li Wanjing, who was also drinking tea, almost squirted out tea on the spot and he asked shakily, "What? Conquer all the families in Martial City?"

Yang Song frowned and looked at Li Wanjing, "What? Do you have a problem with it?"

"No, I just…" Li Wanjing gulped slightly and calmed down, "I don't have any problem with it. But this task is too… difficult, right, Master?"

Yang Song did not answer the question right away, but he asked leisurely, "Say, with my strength and ability, do you think I am weak?"

Li Wanjing naturally quickly shook his head in denial, "No, Master, you are very strong. In the entire Martial City, your strength and ability should be at the top…"

Yang Song suddenly interrupted him, "Only Martial City?" Yang Song asked, "Have you seen the video about the Sword Immortal slaying the abyssal demon circulated on the internet?"

Hearing this question, Li Wanjing suddenly thought of something and was stunned, "Master, you mean… that Sword Immortal is you?"

"What do you think?" Yang Song narrowed his eyes at Li Wanjing and took a sip of tea.

Li Wanjing swallowed his saliva. So that was why he thought the Sword Immortal on the internet looked quite similar as if he had seen that person somewhere.

It turned out that the Sword Immortal was no one else but the expert who almost slapped the Li Family into dregs not long ago. In other words, he was the old patriarch of Tong City's Yang Family – Yang Song.

But his appearance… well, when Yang Song came that day, he was in an old man's appearance, not his original appearance. And today, he was also in that old man's appearance.

With his magical ability, it was not strange that he could change his appearance at will. But what Li Wanjing felt astonished about was that he should be the only person who knew this truth.

Because in these several days, Martial City was in a jumpy state as many people were trying to find the Sword Immortal. But unfortunately, even those giant organizations were not able to find the person in question.

But who knew that a family leader like Li Wanjing actually knew the Sword Immortal and it was not just limited to that…
