Divine fortune teller and traditional Chinese medicine doctor

"Amu, did you find something?"

Seeing Li Mu walk straight to the right front, Zhang Jie quickly chased after him and asked.

"I've discovered there might be rare metals underground ahead. Let's go investigate."

Li Mu responded.

"Rare metals? Are they metal ore veins?" Zhang Jie asked again.

"I'm not sure, we'll find out when we go down."

"Even if you manage to mine metal ore, refining it is very complicated. Spirit stone ore, however, is worth mining. Brother Mu, do you really need rare metals?"

Zhang Yu asked curiously.

There's nothing wrong with her asking that.

Metal mines are usually mined by sects or families because the projects are generally large-scale, and the mining process involves refining, which is quite complex.

Therefore, individuals will not mine any metal ores.

Cultivators need rare metals, which they usually buy.

Spirit stone mines are different; they directly extract the purest spirit stones, which can be used immediately.

Therefore, Zhang Yu found it rather strange that Li Mu was so excited about discovering the metal mine.

"Yes, rare metals are also very precious natural treasures. Moreover, what's buried here might not be metal ore, but rather finished metal materials?"

Li Mu responded and then went to where Wu Xing was.

"Finished metal materials? Then it can't be natural; someone must have buried it here. Could there be a treasure underground?"

Zhang Jie made a bold guess.

"Treasure? My goodness, if there really is a treasure, we'll be rich!"

Upon hearing her brother's words, Zhang Yu immediately became excited.

"But it's strange, I couldn't detect any metallic scent at all. I probed the ground with my spiritual sense and found nothing but soil, rocks, and tree roots. Amu, are you sure there's some rare metal down there?"

After exploring underground for a while, Zhang Jiechao asked Li Mu with a puzzled look.

"Yes, I'm sure." Li Mu nodded firmly.

In fact, he couldn't detect any metallic scent underground, nor could he detect any metallic materials.

However, Wu Xing firmly believed that rare metals were hidden deep underground.

As a metal-devouring beast, Wuxing's sensitivity to the aura of metal is definitely unmatched by them.

Moreover, Wuxing's strength is far greater than theirs.

"Don't hesitate any longer. The metal is deep underground. Go down and investigate. If it weren't for the fact that I exhausted a lot of my primordial spirit power teaching you the non-Five Elements cultivation method, I would have gone down and dug it myself."

Seeing Li Mu and the other two standing there hesitant and doubtful, Wu Xing directly transmitted his voice to Li Mu.

"Oh? Teaching you cultivation methods has taken a toll on you?"

"Yes, and it directly depletes my primordial spirit power, so my main body needs some time to recover. Of course, if I can find high-quality metal, it will greatly benefit my recovery."

"Alright, then you can focus on your recovery."

Without further hesitation, Li Mu dived directly underground.

Zhang Jie and Zhang Yu followed closely behind.

For cultivators at the Divine Realm, escaping underground is a very common supernatural ability; moving underground is almost the same as moving in water.

Whoohoo!

So the three of them went underground.

The terrain beneath this desolate trial ground is basically composed of soil, gravel, and some tree roots.

Therefore, this type of soil moves relatively faster than in mountain rocks and rock layers.

Moreover, when they burrowed to a certain depth, the tree roots disappeared. However, the texture of the soil and rock did not become softer; instead, it became harder.

However, as long as there are no barriers or restrictions underground, Li Mu and his two companions can travel freely without hindrance.

When they dived to a depth of about three or four hundred meters, Li Mu and the other two discovered that there seemed to be a restriction beneath their feet.

Because array formations and restrictions usually also release a certain amount of spiritual energy. However, this spiritual energy is very weak, so it cannot dissipate to the surface. This is why they couldn't sense or detect the deep underground restriction at all on the surface.

Even deep underground, the range of soul perception will still be somewhat hindered.

When they discovered the spiritual energy emanating from the barrier, their souls followed this faint spiritual energy to explore and sense it deeper underground.

Whoohoo!

However, just as Li Mu and his two companions were cautiously continuing their descent towards the location of the restriction, a sudden change occurred.

Suddenly, a powerful devouring force surged from the depths of the ground, engulfing the three of them.

Startled, Li Mu immediately tried to use his teleportation ability to escape, but this underground space seemed to have been locked by an invisible force.

His body completely lost control, and he was rapidly pulled downwards by the force of being swallowed up.

Zhang Jie and his sister Zhang Yu were much weaker than Li Mu, and they had no way to escape this powerful devouring force.

Moreover, as their bodies were pulled deeper into the earth by this devouring force, they sank with increasing speed. The deeper they sank, the faster they went, until finally they lost all awareness of their surroundings.

Finally, the three figures disappeared completely into the dark depths of the underground.

He didn't know how much time had passed, but when Li Mu regained his senses and slowly opened his eyes, he found himself in a dry and very bright underground space.

Zhang Jie and his sister Zhang Yu woke up almost at the same time, and the three of them looked around in astonishment.

Although this underground space was secluded, it was brightly lit as daytime by an unknown source of light.

The spiritual energy was also very rich, with no feeling of stuffiness at all.

Li Mu saw that the secret chamber was surrounded by smooth stone walls. But upon closer inspection and examination, he discovered that the surrounding stone walls were not made of stone, but of some kind of metal.

Li Mu didn't recognize these metals, but they were clearly not ordinary metals.

He wondered if the metallic aura that Wuxing sensed was the metal on the stone walls of this enclosed underground space. The underground space was empty and very quiet.

When Li Mu and the other two woke up, they were all in a state of great shock and no one spoke.

"Ah, Amu, what is this?"

Zhang Jie broke the silence first, his voice trembling with fear.

"Brother Mu, what just happened? What swallowed us up here?"

Zhang Yu stared at Li Mu with horrified eyes and asked.

"I don't know either. But it seems we've stumbled into some kind of secret realm. The restrictions we detected earlier must be the restrictions outside this secret realm."

Li Mu shook his head in response.

His mind was completely blank at that moment.

"A secret realm? Logically speaking, aren't the outer barriers of secret realms supposed to prevent living beings from entering? How come it's actively sucking us in?"

Zhang Jie looked very surprised and suspicious.

"Yes, it's really strange. Are you two injured?"

Li Mu asked with concern, and then helped Zhang Yu, who was next to him, to her feet.

Feeling warmed by Li Mu's concern, Zhang Yu seemed less afraid.

"We're alright, Brother Mu, you..."

shhhhhh!

Before Zhang Yu could finish speaking, three figures suddenly appeared in front of them!
