Chapter 541: The Yellow Sparrow

How... do we get in?

After finding the Ancient Immortal's Cave, how to enter is another problem.

This cave, though called a cave, is actually a huge palace.

The palace's material is extraordinarily high-grade; even using holy weapons, it's hard to leave a mark on it.

Even,

Lu Xun's weapon forged from divine metal cannot forcibly break through.

This means.

The material used in this palace is almost the same as divine metal.

"No."

After some observation, Lu Xun discovered the situation.

The material outside the palace is not metal, but more like stone.

However, the stone has an extraordinarily high density.

"Good fellow, this is stone from a white dwarf, right?"

After Lu Xun punched it, he murmured.

This stone's density is terrifying.

Its mass is also extraordinarily frightening.

A fist-sized stone normally weighs about one catty.

If it were this kind of stone, a fist-sized piece would probably weigh as much as Mount Tai.

That would be hundreds of billions of tons.

A fist-sized stone weighing hundreds of billions of tons—what would its density be?

Such stone likely comes from a white dwarf, even a neutron star.

No wonder it's an immortal.

Using such stone as a weapon is actually not suitable.

It's too heavy, cannot bear force, and energy cannot flow within it.

Unless it's an Ancient God, a huge mass.

But using it for defense is perfectly suitable.

Just like now, Lu Xun's divine-metal weapon finds it hard to destroy it.

No way, although the weapon's material is high-grade, its rank is too low; Lu Xun needs to nurture it.

"The stone has been fused into a whole; what temperature would be needed to melt them?"

Lu Xun was again amazed by the Ancient Immortal's craftsmanship.

This Ancient Immortal is truly powerful.

In the universe, some things that are extremely terrifying to cultivators are like toys in the Ancient Immortal's hands.

"Completely sealed, this is not easy to enter."

Lu Xun spent some time examining the entire palace and found it completely sealed.

Wanting to enter is not easy.

"It's not impossible to destroy..."

Lu Xun thought of a method.

Gather chaos cells onto the chaos dragon's claw; the chaos dragon's claw is entirely composed of chaos cells.

Thus, the chaos dragon's claw can break through this layer of defense.

But Lu Xun currently does not have enough chaos cells.

After thinking, Lu Xun restored normal time in the inner space.

Then,

He moved the chaos cells sealing the inner space out, concentrating them all onto the claw.

"Still not enough."

Still not enough.

Fortunately, at the time of parting, Barbara gave Lu Xun one million cubic units of dark energy.

Lu Xun absorbed most of that dark energy, producing more chaos cells.

Now it's barely enough.

"Come on!"

Lu Xun moved his claw and forcibly broke open the outer shell of the palace gate.

After breaking the outer shell, Lu Xun found that the palace gate was still difficult to deal with.

The palace, together with the external octagonal block and the even more external stellar grand formation, forms a whole.

The palace itself is also extremely hard to enter.

Lu Xun did not give up.

If an Ancient Immortal's cave were this easy to enter, that would be problematic.

"Forcible entry is not impossible, but it would destroy the overall balance..."

After researching, Lu Xun made a discovery.

When the chaos dragon's claw is precisely transformed, with the claw tip completely turned into chaos cells,

the claw tip becomes extremely sharp, able to chip away a hole in the palace gate bit by bit.

The problem is,

The palace and the grand formation are a whole; if Lu Xun really did that, it would destroy the balance and cause the palace to fall into the black hole.

No,

If Lu Xun doesn't first resolve the restriction formed by the grand formation plus the palace itself, he simply cannot break the palace gate.

At the critical moment, one still has to rely on the formation.

"How complicated."

This restriction is formidable.

To Lu Xun, it feels like an immortal seal.

Combined with the stellar grand formation outside and the dark energy provided inside the palace, the difficulty of breaking it is not ordinary.

Even with Lu Xun's current attainments in formations, it is still somewhat difficult.

Lu Xun had no choice but to study it slowly.

"Lan Xing should have entered a new node by now, right?"

Another few months passed.

Lu Xun thought of Lan Xing.

He has now been away from Lan Xing for almost three years.

Lan Xing has probably entered a new node of the ancient road.

This time Lu Xun cannot make it back.

Fortunately, he has brought Chu Youqing, Murong Wan, and the other women with him.

Their cultivation is no problem.

After several months of research, Lu Xun has not made any significant progress.

Lu Xun is not discouraged; he continues his research.

In the blink of an eye, another few months have passed.

"Got it!"

At last, Lu Xun has found a way to break it.

This method is a bit risky; it could cause the palace to fall into the black hole.

But it's worth a try.

He left this place and began setting things up.

One month later,

Lu Xun returned to the palace again.

"Come on!"

Then he activated his preparations.

"Humm~"

The entire Spirit Realm trembled.

The palace likewise began to shake, swaying on the verge of collapse.

"Now!"

He used the grand formation to strike the restriction.

This move indeed worked; the restriction showed a flaw.

"Now!"

With a flick of his claw, Lu Xun burst open the gate.

After breaking it open, however, he did not enter right away; instead, with a thought, he split off a strand of his will and sent it inside.

As for Gu Yao, Lu Xun will not fully believe him.

Even if he has sworn an oath.

What if there is a trap inside?

For example,

The ancient immortal might still be alive.

Or perhaps he is slumbering within.

Lu Xun dares not gamble.

Just as his will entered,

suddenly,

Lu Xun sensed something amiss, flashed his figure, and dodged a strike.

"Not bad, quite quick!"

A cold fluctuation came.

This is a spiritual fluctuation, yet it gives Lu Xun a sinister feeling.

Unexpectedly,

And there's a yellow sparrow!

The other party did not know where it was hiding; only when Lu Xun opened the Ancient Immortal's Cave Dwelling did it suddenly pop out.
