The behavior of the Earth Rock Rat fell into the eyes of several monks present.

The two fake elixir masters didn't care much.

They repeatedly explored every corner of this path, and found very little, confirming that nothing was missing.

Tsk~

The rock rat raised its paw and lightly scratched half of the wall, causing a tooth-gripping sound.

There is a shallow crack left on the wall of the ancient building.

The hardness of the wall exceeds that of ordinary magic weapons.

Seeing this scene, Tan Zhenren's eyes flashed with a hint of sarcasm.

"The ancient building materials in this ruins are relatively hard. But they are not high-grade materials. They are the result of quenching and compressing low-grade mineral materials and casting spells."

Hu Zhenren explained slightly impatiently.

"Um."

Lu Changan had already seen this.

The buildings here, including the floor materials, are simply hard, lacking in actual grade, lack spirituality, and are not suitable for weapon refining and secondary use.

"I trust the rock rat's sense of smell."

Lu Changan smiled slightly and walked to half of the wall of the ancient building.

In fact, what the Earth Rock Rat did just now was secretly instructed by Lu Changan.

Lu Changan took out a magic weapon and a pickaxe, used his magic power, and pointed it at the wall to dig.

Seeing this, the rock rat also waved its paws and began to flap.

Bang bang! Bang bang!

One person and one mouse were tapping and tapping rhythmically in front of the wall.

The walls are peeling off and cracking bit by bit.

Tan Zhenren and the five monks had expressions that were either weird or disdainful.

Until a certain moment.

Lu Changan's pickaxe, a magic weapon, could not knock somewhere on the wall. Instead, it was shaken so hard that his palms were slightly numb.

The same goes for ground rock rats.

One person and one mouse avoided this small area.

"Huh?"

Hu Zhenren had a strange expression. He carefully explored the area with his spiritual consciousness and finally found some clues.

Preliminary judgment shows that the material of the wall is much stronger, and even the late second-level monsters cannot be hurt at all.

In addition, that area has a certain shielding effect on spiritual consciousness and can easily be ignored.

Lu Changan and the Earth Rock Rat increased their speed and knocked down all the walls around that area.

Soon, a piece of gray-white stone as big as a basin fell into Lu Changan's hands.

Parts of the gray and white stone reveal a dark metallic texture.

"What material? Can it actually block the consciousness of this real person?"

Master Tan squinted his eyes and stared at the stone in Lu Changan's hand.

"This is [Shadow Stone]! It can cover spiritual energy and shield spiritual consciousness. It is an excellent material for making concealment and shadow magic weapons."

Miss Wei, who was wearing a gauze skirt with long hair, suddenly lost her voice in surprise and her pretty eyes flashed with light.

"It's actually [Shadow Stone]?"

"The lowest grade of this stone is the third grade. This stone can deceive us many times. I am afraid that it has reached the third grade and can be used to create a mid-grade magic weapon."

Master Tan and Master Hu looked at each other with emotions in their eyes.

"Little friend Lu, it is still unknown whether this object is a [Shadow Stone]. Let me identify it."

Master Tan's eyes flickered, he raised his hand and said.

"It is indeed [Shadow Stone] without a doubt. No identification is needed. This Miss Wei is very knowledgeable. She actually recognized it at a glance."

Lu Changan smiled.

"Show it to me for a look." Master Tan said solemnly.

"Haha! This thing must be related to Lu."

Lu Changan put away the [Shadow Stone] and ignored the fake elixir spiritual pressure emanating from Master Tan.

Master Hu pressed Master Tan's arm and winked.

"Master Tan, please don't be impulsive. Although the [Shadow Stone] is rare, its appeal to fake elixir monks like us is far less than that of true elixir monks."

After hearing the message, Master Tan suppressed his dissatisfaction.

The fake elixir master can only barely use the lowest level magic weapon, and cannot exert its true power.

Common magic weapons in the world of cultivating immortals, like magic weapons, are divided into low-grade, medium-grade, high-grade and top-grade.

Suitable for Jie Dan Zhenren and most Nascent Soul stages.

Low-grade magic weapons, fake elixirs and real elixirs are mostly used in the early stages.

Middle-grade magic weapons are generally used in the middle and late stages of true elixirs.

Therefore, the appeal of this third-grade high-grade [Shadow Stone] to the fake elixir master is mainly its value and scarcity, and it can be traded with the real elixir monk.

"Forget it, let him keep this thing for a while."

Master Tan quickly figured it out.

For the two fake elixir masters, the greatest hope in the ancient ruins is the opportunity to take the fake elixir further.

This kind of opportunity is rare in today's world of immortal cultivation, and it requires the cooperation of True Monarch Nascent Soul.

However, in the ancient times of the world of immortality, the opportunity to take fake elixirs a step further was relatively easier to obtain than today.

…

"Little friend Lu, it is your luck that you found this [Shadow Stone]. I will not pursue it for the time being. If the treasure is obtained by jointly breaking the ban later, it will be distributed according to the level of cultivation and effort."

Master Hu stepped forward and reminded.

"Thank you Master Hu for your adult beauty."

Lu Changan cupped his hands and said.

He was already prepared for Master Tan to force him to hand over the [Shadow Stone].

If that's the case, Lu Changan actually doesn't care. The worst he can do is leave it to the other party to keep it for a while.

Before forming the elixir, [Shadow Stone] had little effect on him.

However, the [Shadowless Needle] and [Shadow-Split Sword] made of this stone as the main material, including some hidden magic weapons and props, are very suitable to Lu Changan's appetite.

In his previous life, when Lu Changan was in the late stage of pill formation, he spent a lot of money to obtain a piece of [Shadow Stone], which was also a third-level high-quality piece, but it was not as heavy as this one.

Because he had dealt with the [Shadow Stone] and was familiar with its characteristics, Lu Changan only discovered the clues when his consciousness swept over it just now.

As far as Lu Changan knows, the [Shadow Stone] with the highest records in the world of immortality can reach the fifth level. It is called the Shadow Stone Essence and can even be used as a refining material for legendary spiritual treasures.

"Go and search the area."

In view of Lu Changan's gains, Master Tan and Master Hu stopped and led three foundation-building monks to explore the area.

"The ancient building nearby used to have a workshop for smelting iron."

"The [Shadow Stone] discovered by Lu Changan may have been secretly hidden by the weapon refiner in the workshop."

The two real people analyzed it very clearly.

But in the end, there was nothing gained. I just found a few worthless scraps of weapon refining materials in the underground ruins.

"Could it be that Lu Xiaoyou's rat demon spirit pet has the blood of a treasure-hunting rat?"

Hu Zhenren looked at the rock rat with a smile, feeling a little jealous.

That [Shadow Stone] is so hidden that it eludes the real person's consciousness, yet it can be detected by the Earth Rock Rat.

The rock rat shuddered and hid in the corner of the ruins, ignoring him.

"Maybe it's a coincidence."

Lu Changan said perfunctorily.

The Earth Rock Rat was just a cover, and he did what he did just under his instruction.

Otherwise, Lu Changan himself discovered the [Shadow Stone], which would easily arouse the vigilance of the two real people, making them more fearful and wary of him.
