The improvement of strength is undoubtedly an unexpected joy.

For Lin Yang, this is not just a threshold for the fourth level of the Golden Pill.

More represents the third level of Linyang Golden Pill, the second level of the golden elixir, which is the continuous improvement of the hidden dangers left behind!

Sure enough, the power of heaven on the altar suppressed, tempered the body, and the illusion tested and honed the mind, and the puppets appeared and stimulated their potential! In addition, the pursuit of Jing Wuxiu and others made Lin Yang's potential explode.

"hiss……"

After being delighted, Lin Yang took a deep breath and felt relieved.

"Now, let me see what the opportunity I got this time!"

Thinking of this, Lin Yang's eyes flashed.

"Come!"

With a light shout and a trembling wrist, Lin Yang sacrificed the opportunity in the storage space!

Just like a coffin, there are some differences.

This object is like a coffin and is very exquisite.

However, compared to Lin Yang's height, it is smaller. It is made of Vajra, carved with ancient patterns and inlaid with colorful gems!

These colorful gems are densely packed and covered with iron coffins. If you look closely, you can see that these gems seem to be chaotic, but they have formed some rules!

"This iron coffin is an extremely precious thing, right?"

Lin Yang murmured softly.

"What exactly is it contained in it? Why has it become the core of the entire ancient ruin?"

Lin Yang frowned.

Thinking of that altar and the boundless underground world, Lin Yang's doubts became increasingly greater.

Obviously, this ancient ruin is somewhat unusual.

Especially that underground space.

Why connect all directions?

It seems that it is to lead everyone into that underground world.

You know, at that time, there were at least two thousand people who fell and were still alive. After that, monks arrived one after another.

All of this seems to be a thrust of energy pulling in the dark.

Plus the abandoned ancient city, the touching puppet, the weird altar...

This made Lin Yang look at the iron coffin in front of him a little more solemn.

"open!"

Finally, Lin Yang shouted with a serious look in his eyes.

At this moment, next to Lin Yang, the unfinished sword formation was placed, but the flowing light flying sword, the white light sword and the all-spirit seal!

Even the last Tianbeng Jade Talisman was sacrificed.

Lin Yang wants to make sure that if an accident occurs, he can save himself as soon as possible!

Rumble...

Under the urging of Lin Yang's vitality, the closed sarcophagus made a low sound, like thunder roaring, and finally slowly opened.

The entire time and space seemed to be shaking and trembling in the low roar.

The sound was like traveling through the eternal sky and experiencing the prehistoric times.

Time stagnates at this moment.

Space is frozen at this moment.

Lin Yang widened his eyes, afraid of missing any link.

Wow...

Finally, as if a century had passed, the tightly closed iron coffin was opened.

It is hard to imagine that the lid of the small iron coffin is so heavy? It is like a mountain.

Even Lin Yang couldn't help but breathe heavily when he opened the lid of the coffin.

"This is……"

When Lin Yang looked into the open iron coffin, his pupils shrank and his eyes widened.

There seems to be another world inside the coffin!

White mist is shrouded in and cold air is overflowing, like a trap?

A rich spiritual energy burst out, making the entire underground world more exciting.

"Inside the iron coffin, is the eternal ice soul actually used as the material?"

Lin Yang couldn't help but exclaim.

As white as jade, cold air is everywhere, and it remains unchanged forever.

What is this not the eternal ice soul?

Rumor is that the eternal ice spirit is a precious material that was born in an extremely cold place when chaos first opened and the world first appeared.

If this object is used to refine magic weapons, the magic weapons will be full of spiritual energy and form a lineage, and the cold energy will hit people. If a monk is injured by such magic weapons, the wound will be frozen instantly, and the tendons and veins around his body may even solidify. Cold poison enters his body, and those with poor strength will instantly turn into an ice sculpture and die in the underworld!

This is the material that countless monks dream of.

And the other biggest function of this thing is storage!

Elixirs, medicinal materials...

Any precious thing will remain unchanged for thousands of years and the effect will not fade away!

So this is also the container that countless alchemists dream of!

In addition, this object has another function.

It is said that this object is used as a burial object and will be buried in it for thousands of years. It can even retain the three souls and seven spirits one day and be reborn.

Therefore, there are too many legends in the ten thousand years of ice soul.

However, with the changes of the times and the passage of time, the ten thousand-year ice spirit has become extremely difficult to see, and it is really something that is hard to find.

Unexpectedly, the inner layer of such a large iron coffin is actually the ten thousand-year-old ice soul?

Not to mention anything else, just this ten thousand-year ice soul is enough to make it difficult for many monks to control, right?

"Is it really a human being that is sealed here?"

When Lin Yang came to his senses, the corner of his mouth twitched.

He thought of Yan Luo!

Isn’t Yan Luo just breaking out of the coffin and rebirth?

I thought I had a huge opportunity?

And this time Yan Luo appeared here again...

This forced Lin Yang to think about some more things.

Especially when Lin Yang did not forget what Zi Silk said.

At that time, Zi Siw once said that there was a ray of fairy aura in that underground space! It was the breath of a fairy.

And that breath came from the iron coffin without any surprise.

If this is the case, if someone really lies in the iron coffin, wouldn’t he be an immortal?

Lin Yang felt suffocated.

Seeing the lingering cold air gradually dissipating, Lin Yang frowned and looked inside carefully.

"No! This is..."

Finally, when the cold air that had been deposited for thousands of years gradually became thinner and the truth in the iron coffin was revealed, Lin Yang's pupils shrank and his face changed again.

What he was worried about was never happening.

There was no one lying in the iron coffin!

However, there is a blue ancient lamp left in the pinch of the iron coffin.

The ancient lamp stands, as if it records the breath of time. The complex patterns carved are like traces of time.

The entire ancient lamp even gives people an old feeling.

If it is placed in an ordinary place, it will not even attract too much curiosity?

"Inside the iron coffin, seal the ancient lamp? Why is this?"

Lin Yang is a little messy.
