Mu Jinyu once again followed the space rift back into the hidden mountain behind Mount Tai.

The seven people, led by Wang Tengfei, looked at each other, wondering in their hearts what Mu Jinyu was trying to do.

Was he going to use them to trigger some restriction or what?

Despite their doubts, they still felt that Mu Jinyu probably wouldn't do such a thing, right?

After all, he just said that their strength wasn't enough to trigger the restrictions.

Thus, they also stepped through the space rift and entered the actual mountain body, folded by restrictions.

"Dragon Master…"

Once inside, they saw Mu Jinyu already standing before the wall of light fog, holding a long spear magic treasure, probing forward.

"Dragon Master, no!"

"That's dangerous. Touch it and you'll almost certainly die!"

Wang Tengfei and the others were terrified by Mu Jinyu's actions and quickly tried to dissuade him.

When they first arrived at Mount Tai, they saw the folded mountain range behind it was cut into small sections. They had also wondered why Mount Tai was different from other famous mountains.

Consequently, some attempted to pass through that wall of light fog to directly reach the surrounding, sectioned-off but still connected areas.

But without exception, those who dared to try ended up dead.

Seeing Mu Jinyu's actions, they were all startled, and those hoping to gain some benefits from Mu Jinyu at Mount Tai naturally didn't want him to just die like that, so they all began to persuade him.

However, just when they thought Mu Jinyu would heed their advice and stop his actions, like he did before.

This time, Mu Jinyu didn't listen to their advice and continued recklessly with the long spear, pushing it into the light fog.

"Zzzz!"

"Crackle!!"

Instantly, countless obscure runes intertwined in the light fog wall, beginning to corrode the spear, turning it to ashes while rapidly spreading upwards.

The speed was very fast, and before Wang Tengfei and the others could react, the rune had already reached Mu Jinyu's fingertips.

Unexpectedly, just when they thought Mu Jinyu was surely doomed, Mu Jinyu let go of the spear just as the runes were about to erode his hand.

Mu Jinyu watched another spear magic treasure disintegrate, silently noting those strange runes, then turned to Wang Tengfei and the others, asking, "Did you ever try this light fog wall? Can it connect to other areas?"

Hearing Mu Jinyu's words, Wang Tengfei and the others snapped out of their shock.

They gulped hard, casting disbelieving glances at Mu Jinyu before speaking in a choked voice, "Someone tried before, but all died, so we don't know if it connects to other areas."

Mu Jinyu asked again, "About higher up, like folded spaces on the mountainside, are the light fog walls there more powerful than those in the lower areas?"

"Uh…?!"

Hearing Mu Jinyu's words, Wang Tengfei and the others pondered, then uncertainly said, "Seems stronger than the ones down here?"

"Alright, got it."

With their answer, Mu Jinyu nodded, then asked a few more questions.

After obtaining their responses, Mu Jinyu felt more confident.

He saw no need to leave this folded space and climb to the mountainside for research.

He planned to directly force his way through.

Then, Mu Jinyu systematically pulled out dozens of ordinary magic treasures from his storage bag to experiment with the light fog wall, studying the hidden runes that emerged.

His actions stunned Wang Tengfei and the others.

At first, they thought Mu Jinyu was courting death and advised him against it.

After all, one can succeed in courting death countless times but can't bear the consequences of failing even once.

Yet after a dozen attempts with Mu Jinyu still unscathed, they began to wonder if the light fog wall's erosion could indeed harm Mu Jinyu.

Or maybe Mu Jinyu was confident in dancing at the edge of the cliff without trouble, hence his relentless attempts?

They didn't know but all fell silent, no longer advising Mu Jinyu against courting death.

Another magic treasure was destroyed as Mu Jinyu memorized the runes and took out another treasure.

He actually felt a bit annoyed after sacrificing over a dozen magic treasures already.

If possible, he really wanted to test the Dragon Spear, a heaven-reaching spiritual treasure, to continuously trigger the wall's runes for uninterrupted observation instead of stopping to check each time.

But he didn't dare recklessly try.

After all, it's a heaven-reaching spiritual treasure; if it got destroyed in testing, he would be deeply distressed.

Better use ordinary magic treasures.

After sacrificing five more treasures, Mu Jinyu's eyes gleamed with excitement.

He finally succeeded in mastering one rune.

Then Mu Jinyu stopped attacking the light fog wall and brought out a small magic treasure, engraving that rune onto it.

Wang Tengfei and the others continuously watched Mu Jinyu's actions and saw when he engraved the rune on the treasure, their pupils shrank sharply.

"This is…"

In their senses, the treasure in Mu Jinyu's hand still had spiritual power fluctuations.

But as the rune appeared, the degree of those fluctuations greatly decreased, and unless observed closely, it seemed just like an ordinary weapon under their divine sense.

Then Mu Jinyu engraved a second identical rune.

In Wang Tengfei and the others' perception, the treasure utterly turned into a normal weapon.

And after he engraved a third rune, they found that just by divine sense, there was nothing in Mu Jinyu's hand at all.

"This…"

Wang Tengfei opened his eyes, looking at the treasure indeed present in Mu Jinyu's hand, feeling chills run down their spines.

This was when they finally understood why Mu Jinyu stayed in this seemingly worthless folded space repeatedly attacking the light fog wall.

He had discovered the immense value of these runes.

Mu Jinyu then engraved a fourth rune on the treasure.

But nothing happened.

It seemed three runes were sufficient.

Mu Jinyu frowned slightly, then crouched down, digging a small hole and burying the treasure inside.

No one's naked eye or divine sense could detect that there was a treasure buried beneath this pit.

However, Mu Jinyu knew that some people are born with special eyes like the Double Pupil, Heavenly Vision, Eyes of the Netherworld, and those with such heterochromia might be able to see through the rune's concealment.

But he didn't mind much; the rune's value is immense, and such people are quite rare.

Thus, Mu Jinyu continued to crack the light fog wall, further learning various runes within.

Finally, after half a day.

Mu Jinyu comprehended all the forbidden runes in the light fog wall.

Then with a wave of his hand, the light fog wall dissipated automatically.

Revealing the other folded space behind it, originally sectioned-off, forming another whole.

Wang Tengfei and the others were dumbfounded seeing this scene.

Was this even possible?!
