Supreme Grandpa

Fortunately, his storage space contained a lot of Inner Cores obtained from killing abyssal demons during this period of time, and the True Energy in his body could be more or less replenished to catch up.

But even so, it was not a good choice to consume it like this.

His current advancing speed was too slow. At this speed, when he rushed to the core zone, the purpose of the abyssal demons might have been achieved long ago.

After hesitating again and again, he finally decided to give it a go.

He immediately took out the Blue Bolt Sword and flew high into the air, then, he swiftly operated the ability of the Blue Bolt Sword – Sky Thunder! This name was given by Yang Song.

Suddenly, a large expanse of cloud centered around him, making the sky gloomy, and countless arcs of thunders swam around crazily.

"Go!"

With a thought from Yang Song, many bolts of thunder rained down in a huge area, and many abyssal demons in the air were blasted to the ground by the powerful thunder.

In the air, it became clear.

Why didn't he use this ability in the first place?

Simple, because it consumed too much True Energy. With this quick attack, it consumed half of his True Energy already.

Previously, when he used this skill to scare the top nine families in Martial City, he actually only operated a small part of it.

When Yang Song went to the core of the abyssal demons this time, he also had to face two S-level abyssal demon "bosses", and he had to save a certain amount of strength "on the road".

Seizing the opportunity to clear the air, he restored his True Energy and headed towards the core area and advanced at full speed.

He originally thought that the closer to the core, the denser the number of abyssal demons, but the actual situation was a bit beyond Yang Song's expectations.

When he broke through the enclosure of the outer abyssal demons and came to the core area, he was surprised to find that it was extremely empty.

However, being empty did not mean that the defense here was bad.

A huge red energy shield was presented in the core area.

In the center of this energy shield, the two S-rank abyssal demons who had just fought Yang Song outside were there.

At this time, they were surrounding a huge purple energy magic ball.

And the ground below this magic ball was continuously releasing powerful space element energy toward the outside world.

Obviously, this magic orb, or something under the ground under this magic orb, was the target of the abyssal demons this time.

"They sent such a big battle for this thing?"

Yang Song didn't know what was the use of this thing, but since the abyssal demons had to get it at such a high price, even thinking about it with his ass knew that it was definitely not simple.

Inside the energy hood, the two S-rank abyssal demons had discovered Yang Song, but they did not take any other actions, and were still focused on continuing to output a weird energy on the magic orb.

Under their strange operation, the magic ball actually slowly sank toward the bottom of the earth!

"In this case, their goal is something underground."

These two abyssal demons were not Yang Song's opponents. Now Yang Song was catching up, but they were not nervous at all, all relying on this red shield around the core area.

Well, Yang Song tried it, only to find that this hood was far stronger than he thought. 

He tried some common skills, but there was no obvious effect.

"I'm afraid that only the true attack of the Ten Thousand Returning Swords Art could break it open forcibly."

However, the two abyssal demons inside were not just for show either, and they were still S-rank. It was still necessary for him to maintain his own state. If he used that technique in this way, his True Energy would be consumed greatly.

After thinking for a while, he muttered, "Maybe, it can be like this."

Advanced-rank talisman – Lesser Past Revealing Talisman.

This was a type of talisman that Yang Song took interest in and used a great deal of True Energy to refine it.

To refine this single talisman, Yang Song had to use more than 80% of his True Energy, which could show how magical this talisman was.

As its name suggested, it was a talisman used to see the past event of a certain place, person, animal, and many more.

However, this was a "Lesser" version, not the true version, therefore, the past couldn't be fully revealed at all. At most, it could only reveal the past even of the half-day before.

But this was more than enough.

Yang Song swiftly activated the talisman.

Soon, the scene of the arrangement of this energy hood appeared like a video in Yang Song's mind.

"I was wondering how could these two abyssal demons arrange such a powerful energy shield, so that's how it is."

In the manifestation, in order to arrange this energy shield, the abyssal demons actually used eight spatial cracks.

These spatial cracks were not used to transmit abyssal demons, but to transmit energy to arrange this huge red shield in the core area!

After seeing this past, Yang Song even doubted whether the peak move of the Ten Thousand Returning Swords Art could really break the red cover...

However, in Yang Song's plan, he did not intend to use it to break through.

According to the actual situation, the time for the arrangement of this red hood was not long.

"If so, is it possible to..."

Yang Song focused on the part of the red hood in front of him.

Then, he swiftly went to arrange two formations – Innate Blood Demon Killing Formation and Innate Mirror Formation.

With the previous experiences and preparations in advance, Yang Song finished drawing the symbols of the two formations before long.

"I don't know whether it will work."

As Yang Song waved his hand, 16 formation flags flew in different directions and disappeared.

Yang Song had two main flags in his hands, and with a thought, a rumbling sound appeared, shocking the two abyssal demons.

Yang Song let out a grin, "It really works. Two different formations can be used together, and the source of the energy that supports the red energy cover is really cut off…"
