The Mutant of the Thunderbeast

Within the cave, bolts of lightning swirled around, looking rather illusory.

Su Tong could feel the chaotic thunder-attributed spiritual energy and also exited his cultivation state.

"Little Thunder?"

Su Tong then looked towards the inside of the cave behind him.

He discovered that the Thunder Crystal Beast was currently emitting arcs of lightning from its body.

These lightning bolts were different from the previous purple ones.

They were actually red lightning.

"After the Thunder Crystal Beast devoured other demon spirits, it actually obtained a trace of mutation?"

After just a glance, Su Tong understood.

At this time, because the Thunder Crystal Beast had devoured other demon spirits, it produced some mutations.

This trace of mutation also caused the lightning of the Thunder Crystal Beast to change from purple to the current red.

"Roar!"

At this moment, the Thunder Crystal Beast also let out a low roar.

Then it controlled those red lightning bolts and absorbed them back into its body.

"Peak of the Returning Void Realm, not bad!"

Looking at the Thunder Crystal Beast's strength now, Su Tong nodded satisfactorily.

The strength of this Thunder Crystal Beast had already stepped into the peak of the Returning Void Realm.

Earlier, when he had obtained the Thunder Crystal Beast, the elder of the Crimson Rainbow Sect had said before.

The strength of the Thunder Crystal Beast at its peak could reach the Returning Void Realm.

That meant the peak of the Returning Void Realm should be the Thunder Crystal Beast's most powerful state.

But the current Thunder Crystal Beast had already mutated.

So Su Tong also knew clearly that the Thunder Crystal Beast's strength in the future would definitely not just be limited to this.

"There is still one demon spirit left, but...forget it, we'll talk again after you break through to the Spirit Void Realm!"

Su Tong hesitated for a moment.

In the end, he did not take out the last demon spirit.

The Thunder Crystal Beast had already stepped into the peak of the Returning Void Realm.

If he used demon spirits to boost its strength, it would be somewhat inappropriate.

So Su Tong also planned to directly let the Thunder Crystal Beast use demon spirits to break through.

Bottlenecks also existed for demonic beasts.

Therefore, Su Tong decided to give it the last demon spirit after the Thunder Crystal Beast naturally broke through to the Spirit Void Realm by itself.

"Roar!"

At this moment, the Thunder Crystal Beast darted out of the cave, appearing by Su Tong's side.

It roared towards the sky, and the animals in the surrounding forest scattered away.

Su Tong looked at the Thunder Crystal Beast beside him. Its height had already grown to nearly two meters tall.

And there was no need to mention its length.

Because of the mutation, the Thunder Crystal Beast's body that was originally purple had now become a dark red.

"So big, bringing it around will be troublesome!"

Looking at the Thunder Crystal Beast beside him, Su Tong was also a little helpless.

Being so huge, bringing it into the city would be quite troublesome indeed.

"Roar!"

As if understanding Su Tong's words, a red glow flashed over the Thunder Crystal Beast's body.

Then the two-meter tall Thunder Crystal Beast gradually shrank down.

In the end, it had shrunk to only the size of a small cat.

"As expected of a demonic beast!"

At this time, Su Tong also knew why demonic beasts were called demonic beasts.

After stepping into the Returning Void Realm, they could control their own body size.

Their intelligence was also close to that of demons.

Once the demon spirit was born, their intelligence would become even higher.

"Let's go!"

At this time, Su Tong directly picked up the Thunder Crystal Beast.

"Now we're going to Fallen Maple City. Since the Evil Spirit Sect has not come looking for us, we'll go find them instead."

For such an unscrupulous sect,

Su Tong did not want to let them off at all.

These past few days, his strength had also improved somewhat, though he had absorbed quite a lot of Nourishing Spirit Pills.

Cultivating with Nourishing Spirit Pills was indeed much faster than absorbing spiritual energy from heaven and earth.

Su Tong took a step forward.

In an instant, he appeared ten-odd meters away.

Then the tips of his feet touched the ground and he rose up into the air.

Not long after, he was outside Fallen Maple City.

At this time, strict defenses were in place outside Fallen Maple City. It seemed like someone had taken over this place.

"Looks like the Evil Spirit Sect should be waiting for me!"

Su Tong let out a cold laugh.

Then he directly headed towards Fallen Maple City.

From afar, he saw a portrait, which was none other than himself.

"Not bad!"

Seeing it, Su Tong nodded satisfactorily.

Then he went straight towards the obstacles set up by the Evil Spirit Sect.

"Stop right there!"

Just as Su Tong walked over, a man directly blocked his path.

"Haha, no need to check, I'm the one you're looking for!"

Su Tong laughed.

Then his hand gently patted over.

"Pfft!"

That man directly spat out a mouthful of blood and was sent flying away.

Seeing this, the others surrounded Su Tong.

"You're not my match. If you don't want to die, get out of my way!"

Su Tong did not attack directly.

The strength of these people was only at the Refining Spirit Realm.

Su Tong was too lazy to make a move against them.

Just now he only struck out to avoid trouble.

Seeing their companion laying on the ground either dead or alive after being slapped away by Su Tong,

those people were also somewhat panic-stricken.

After exchanging glances with each other, they actually all retreated.

"Humph!"

Su Tong humphed coldly, then directly entered Fallen Maple City.

This was Su Tong's second time coming to this city.

Previously, he had not taken a proper look, so now Su Tong also looked around here and there in the city.

He did not immediately go to find the Evil Spirit Sect. After all, he knew that now that he was in Fallen Maple City, the Sect Master of the Evil Spirit Sect would definitely come looking for him.

Su Tong walked along the streets.

There were people coming and going here, unlike within the Crimson Rainbow Sect.

It was also very different from the Northern Territory.

When he was in the Northern Territory, there were only sects, and no cities like this.

So Su Tong had not seen streets like these before.

"Pill Seeking Hall?"

At this moment, Su Tong was attracted by a scent of medicinal pills.

Looking up, he saw an ancient multi-storied tower.

A plaque hanging on it read 'Pill Seeking Hall'.

Without hesitation, Su Tong walked right in.

Having just entered the ancient tower, Su Tong saw many counter-like places displaying all kinds of spiritual herbs.

"Would you like a Wind Poison Rare Mushroom? Only ten Spirit Stones!"

At this moment, a man came over and asked Su Tong.

Su Tong shook his head.

This Wind Poison Rare Mushroom was a first-grade spiritual herb, and also relatively common.

Unless he needed it, not many people would buy it.

Su Tong looked around. These were all third-grade or lower spiritual herbs and pills.

They were of no use to Su Tong at all.

And here, there was also a second floor.

Su Tong looked and then directly headed for the staircase.

"Wait, going up to the second floor requires ten Spirit Stones!"

At this moment, someone stopped Su Tong and said.

Su Tong felt it novel that he had to pay Spirit Stones just to go upstairs and take a look.

But it was only ten Spirit Stones. Su Tong could afford it.

Then he directly headed upstairs.

The moment he stepped onto the second floor, a strong pill fragrance instantly assailed his nose. "Someone's concocting pills?"
