Divine Seal: My Grandfather is the Demon King

The three of them continued deeper.

A cold air blew through the cave, and the air seemed slightly turbid.

They were not moving forward very fast.

The surroundings are still surrounded by dark stone walls, and there are many gems in some places.

These stone walls show no signs of artificial excavation, as if they were cracks that appeared when the mountain split open on its own.

After walking about a few hundred meters, the road ahead suddenly broke and a huge crack appeared in front of them.

The crack is bottomless.

Feng Ling swung the lightsaber and chopped it down the cliff. After a long time, the light did not go out, which shows how deep the cliff is.

What a deep cliff!

Long Haochen has always been a cautious person, and jumping down rashly is not a rational idea.

"Sister, it's so deep, do we really have to jump?"

Moreover, he always felt that his sister seemed to know this place very well.

"Yes, jump down." Feng Ling nodded.

They must hurry, otherwise, the seventh-level demon lord may arrive at any time.

There was no one outside who could fight, but with Xiaoyu's protection, they would not be hurt so easily.

But just in case, Feng Ling and the other three would better decide quickly and decisively.

Suddenly, another sharp roar was heard, followed by a series of deafening roars.

The second fierce roar is coming!

Feng Ling immediately stood in front of Long Haochen and Sheng Caier and released a holy light shield.

Although the shield doesn't play a big role, it can at least weaken some of the fierce roar.

Sensing the mournful howling sounds around him, Long Haochen suddenly had a flash of inspiration in his mind, and he suddenly felt that he had discovered some pattern.

You are worthy of being my brother!

Feng Ling nodded with relief. She saw that Long Haochen was in a state of enlightenment and did not disturb him.

Moreover, from this fierce roar, she also gained a glimmer of enlightenment.

However, it didn't take long for the shield to break!

Feng Ling immediately released a holy light shield again, silently blocking the influence of the sad howl for Long Haochen and Sheng Caier.

As the Son of Light with an innate inner spiritual power of ninety-nine, and with his extraordinary mental strength, Long Haochen's comprehension can be said to be unmatched.

The ripples of Li Xiao have a regular pattern. What if his bright spiritual power can also radiate to the surroundings like the sound ripples?

Long Haochen felt that he had realized something.

Before long, that inspiration could no longer escape and had completely turned into Long Haochen's understanding.

"Sister, let me do it!" Long Haochen stood in front of his sister.

He released a holy light shield. If you look closely, you can find that the originally light golden holy light shield has a hazy feeling.

That’s right, the holy light shield is vibrating!

And it oscillates at the same frequency as the whistling sound waves.

This is the skill that Long Haochen has comprehended, called Rippling Light.

"Sister, Cai'er, that's great. I have learned a skill." Long Haochen's eyes were shining with excitement.

"I named it Ripples of Light."

"Not bad, you are worthy of being my brother." Feng Ling praised Long Haochen for once.

It was the first time that Long Haochen was praised sincerely by his sister, and he felt a little embarrassed.

From childhood to adulthood, although his talent is unmatched, he has always lived under the shadow of the even more talented Feng Ling.

Today, he finally showed off in front of his sister!

and……

Long Haochen picked up the sword in his hand, attached the ripples of light to the sword, and slashed it towards the ground.

He found that the ground could be cut easily like tofu.

Calculating it this way, it means that he only used twice as much spiritual power, and his attack power reached ten times the usual level!

Are the skills he learned casually so amazing?

"I'm such a genius!" Long Haochen was slightly narcissistic.

Not bad, not bad, I look a bit narcissistic.

That’s right!

Feng Ling nodded with satisfaction. People should be a little narcissistic.

"Sister, Cai'er, let me teach you this skill." Long Haochen looked like a little child and was very excited.

However, isn’t Long Haochen just a fifteen-year-old child?

From childhood to adulthood, no matter what difficulties he encountered, Feng Ling would always stand in front of Long Haochen.

Although Long Haochen is now less calm and more childish, he had a happy childhood.

"Okay, brother, I'm all ears." This time, Feng Ling did not bully Long Haochen.

Sheng Caier also nodded.

"I copied the wave rules and trajectories of the howling sound waves into my own spiritual power. When the oscillation frequency of the holy light shield is consistent with the howling sound, the howling sound is completely blocked outside." Long Haochen talked freely.

Feng Ling nodded slightly, closed her eyes, and then, she casually released a vibration on the sword in her hand with the same frequency as Li Xiao.

After finding the right frequency, Feng Ling opened her eyes.

As the Saint of Reincarnation, Sheng Caier quickly learned this skill.

"Sister, Cai'er, since you all know how to do it, let's go down!" Long Haochen stood on the edge of the cliff.

"Okay." Feng Ling nodded, and after the sharp whistling sound stopped, she jumped down first.

Long Haochen and Sheng Caier jumped down without hesitation.

It was pitch black all around, with no sight of one's hand in front of one's face, and a strong smell of death.

This made Long Haochen, who had the light attribute, feel very uncomfortable. Even Feng Ling, who had the dark attribute, felt a bit disgusted by the aura here.

Only Sheng Caier, who possesses the attribute of death, feels at home here.

Finally, after an unknown amount of time, they landed on the ground.

It was cold and dark here, which made the three of them feel alert.

Looking forward, there is an open space.

This space reflects a faint gray light, giving people a sense of unreality that is dead and dreamy.

It was as if they had entered another parallel dimension.

This was not the most shocking thing. There was a tall tower in front of them.

That’s right, it’s a seven-story tower.

This tower was of an ancient style, emitting a thick grey halo from all directions, filled with deathly silence and terrifying spiritual fluctuations.

Surrounding the tall tower were countless gray-white lights and shadows, densely clinging to the outer layer of gray-white energy emitted by the tall tower.

Layers of gray halos continued to spread from the tower, and the other three people actually felt a shudder from the bottom of their hearts.

This is a terrifyingly powerful existence!

This is the Tower of Aion!

Feng Ling's eyes suddenly became solemn.

"It seems that this is the secret of the Howling Cave. Let's go into the tower and take a look!"

After saying that, Feng Ling strode forward.

Long Haochen and Sheng Caier did not hesitate and followed Feng Ling towards the tower.

However, after they had walked a dozen steps, the grayish-white ghosts finally noticed them.

In an instant, countless vengeful spirits let out long howls and rushed towards them!
