This small Luban lock actually consists of thirty-six strands.

It is divided into two layers in total, with the outer layer having twenty-four strands.

The inner layer is twelve.

The outer layer must be cracked first before the next layer can be unlocked.

Moreover, there is an isolation formation on the wood on the inner layer, and I can't see through it at all.

It seems that this level is a test of intelligence.

Do you want to try using violence?

Looking at this big Luban Suo, this idea came to Lin Yu's mind.

Thinking of this, Lin Yu stopped caring about anything else, and the Tianling Needle appeared out of thin air in his hand!

He mobilized his spiritual power and instilled it into the Tianling Needle. Holding the wooden box, he controlled the Tianling Needle with his thoughts.

Bang!

With a thought, the Tianling Needle pierced the Luban Lock.

There was a sound of metal and stone colliding.

The next second, Lin Yu felt an arrogant force hitting him out of thin air.

With a bang, the Luban Lock fell off Lin Yu's hand, and his whole body was hit by this arrogant force and flew backwards, and then hit the wall of the fourth floor hard.

A mural hanging on the wall was also knocked off the wall by Lin Yu's body.

After being beaten to a pulp, Lin Yu endured the pain and stood up holding on to the wall, not daring to use any more spiritual power.

The force just now was obviously the force with which he hit the Luban Lock with the Tianling Needle.

Unexpectedly, it was returned directly to me.

The Luban Lock was lying quietly on the ground without any damage.

At this moment, Lin Yu suddenly noticed the painting that he knocked to the ground.

I saw a line of small words written on a corner of the hanging painting.

Hidden, hidden, really hidden, hidden in Zhenwu General, with three souls in the left palm and seven souls in the right palm.

Seeing this, Lin Yu quickly wrote it down, and then ran to other paintings hanging on the fourth floor wall.

Read them one by one.

I saw a line of small words on the paintings on the walls.

Where to hide? Hidden in the Baltic Sea Village. The sky covers the earth and the earth covers the sky.

Clear away the clouds and look at the blue sky. Thousands of evil masters cannot find you.

...

Looking at these carvings, Lin Yu finally had a clue in his mind.

I had never noticed these inconspicuous paintings before.

But I didn't expect it to contain a mystery. If I hadn't been knocked into the wall, I would have carelessly ignored these hanging paintings.

Immediately, Lin Yu came to the center and picked up the Luban Lock that had fallen to the ground.

Immediately, I observed the Luban Lock again with the help of perspective.

Corresponding to the formula memorized in his mind, Lin Yu began to operate.

One pull, one push, one turn, one twist.

...

After a while, Lin Yu pulled out the last piece of mortise and tenon wood, and the outer layer of Luban lock instantly loosened, revealing the true appearance of the twelve layers inside.

Lin Yu wiped the sweat on his head and sighed.

It’s really not easy!

If I hadn't had clairvoyance, even with this recorded formula, I would certainly not have been able to unlock the Luban Lock so easily.

But now Lin Yu looks at this core Luban Lock and is in trouble again.

Lin Yu had read all the paintings on the wall just now.

There were only those formulas, but all the formulas were still used to unlock the twenty-four Luban locks previously.

After thinking for a moment, Lin Yu put down the Luban Lock and observed the scene on the fourth floor.

With the perspective open, everything is exposed.

After a while, Lin Yu discovered a secret on the table leg in the center.

Lin Yu then squatted down and recited these words carved on the wooden table legs.

The law says that the innate Bagua, the middle Taichi diagram is the middle earth, the middle part is the lower part, and the back part is the Bagua. The middle Taichi diagram is the sky, and the middle part is the upper part. If you draw on the sky plate and the beam, you must reverse the diagram.

....

After a while, Lin Yu slowly stood up.

The corners of his mouth raised slightly, a smile appeared on his face, and he already had a certain decision in his heart.

Immediately, the Nine Palaces and Bagua Formation appeared in Lin Yu's hand.

Putting the Luban Lock in the center of his hand, Lin Yu started to twitch according to the formula.

After a moment, there was a crash, and all twelve Luban mortise and tenon locks were scattered on the table.

"Haha, I didn't expect it to be so easy!"

Lin Yu couldn't help but sigh.

But he had forgotten what he had been thinking about with his brows furrowed earlier.

If he hadn't learned the Nine Palaces and Bagua formation, how could he have unlocked the twelve Luban mortise and tenon joints in the core.

Even if you find the formulas written on the table legs, it won't work.

Only someone who is proficient in the Nine Palaces Bagua can understand what this is.

After untying it, Lin Yu opened the wooden box without hesitation.

After opening it, a piece of brocade silk appeared in front of me.

After picking it up and spreading it out, I saw a formation carved on it!

It was similar to his own Nine Palaces Bagua Formation, but just looking at the formation diagram, Lin Yu could feel a powerful murderous intention.

And there are a few small words embroidered on this formation diagram.

Qing Ling Meteor Killing Formation.

After thinking for a while, Lin Yu decided to practice now.

But the next second, the phantom old man appeared in front of Lin Yu.

Seeing this, Lin Yu was dumbfounded!

...

This time Lin Yu didn't want to hear what the old man Xuying said, and said bluntly: "I want to enter the next level!"

Hearing this, the old man Lin Yuxuying nodded, and then with a wave of his hand, a staircase appeared in the corner.

Walking straight up, Lin Yu arrived at the fifth floor.

Before his eyes, Lin Yu appeared outside a volcano.

The ground was hot, and the scarlet lava seemed to be roaring.

Seeing this, Lin Yu quickly took out the Prince Ning Sword.

As soon as King Ning held the sword tightly in his hand, a fire spirit appeared in front of Lin Yu.

The whole body shows a scarlet color, which is completely condensed by these magma.

"What a monster has violated my territory!"

Just listen to the giant lava beast roaring towards Lin Yu.

After saying that, the lava beast punched Lin Yu.

Wherever the fist passed, magma flew away.

Fortunately, this lava beast was relatively busy, so Lin Yu could easily avoid it.

After avoiding it, Lin Yu also took the opportunity to slash away with his sword.

With a bang, the sword intent exploded on the lava beast's body.

In an instant, an eye-catching wound appeared on the lava beast.

But the explosion caused by the collision also caused the magma on his body to fly in all directions.

The moment it flew out, the magma turned into small lava monsters and attacked Lin Yu.

Lin Yu didn't expect that the magma on this lava beast could be like this, and he suddenly lost his composure.
Chapter completed!
