"That’s right! It’s said that the ’Profound Gold Divine Marrow’ is Tier Four or even Tier Five material, and a fist-sized piece is worth as much as the entire vein!"

Fu Chao’s eyes lit up, finally responding and understanding what Li Yunjing meant.

"Old Li, you’re quick on your feet!"

Fu Chao couldn’t help but praise.

"Hehe, average!"

Li Yunjing chuckled softly, glanced at the hard ground beneath his feet, and fell into contemplation.

"What’s wrong?"

Seeing Li Yunjing looking a bit worried, Fu Chao asked.

"This is ’Profound Gold Divine Iron’! For the two of us to cut into the core of the mountain, it will probably take a lot of effort!"

Li Yunjing sighed and spoke slowly.

"Hm? Old Li, with your skills and using ’Gold Escape Technique,’ you can’t reach the core position?"

Fu Chao asked puzzledly.

To Fu Chao, Li Yunjing could do anything, but unexpectedly, he showed a bitter expression here, greatly surprising Fu Chao.

"Of course not! My ’Gold Escape Technique’ is not well cultivated! If it’s Tier Two metal, it can’t stop me; but Tier Three, don’t even think about it!"

Li Yunjing shook his head and took out his ’Yin Yang Five Elements Celestial Derivation Sword.’

"Hiss hiss hiss..."

Drilling into the mountain along the hillside again and again!

Although the "Yin Yang Five Elements Celestial Derivation Sword" isn’t high-grade, its material is extremely powerful, even more top-notch than ’Profound Gold Divine Iron’!

On this ’Profound Gold Divine Iron Mountain’, one can naturally slowly cut out pieces of ’Profound Gold Divine Iron,’ continuing to delve deeper down.

"Dang dang dang..."

Fu Chao wasn’t idle; he took out his ’Red Sun Sword’ and started cutting alongside.

The magical treasures of the two were powerful, and with the added mana, this ’Profound Gold Divine Iron Treasure Mountain,’ although hard, could still be chiseled open.

"Faster! Let’s dig directly into the depths of the mountain!"

Seeing a yard-long cave appearing, Li Yunjing whispered low and waved his sleeve, releasing four Foundation Establishment Realm Sixth Heaven ’Puppet Mechanism Beasts.’

These ’Puppet Mechanism Beasts’ held treasure artifact weapons, such as long sabers and axes, assisting with the excavation! 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

"Hey! Old Li, you’ve got a knack for this!"

Seeing four helpers suddenly appear, Fu Chao’s eyes lit up and he gave Li Yunjing a thumbs-up.

"Haha! Keep it up! I still have ’Puppet Mechanism Beasts’ and treasure artifact weapons! If the space gets bigger, I’ll release more ’Puppet Mechanism Beasts!’ Our efficiency will be even higher!"

Li Yunjing said somewhat proudly.

At this time, Li Yunjing was very fortunate to have cultivated ’Puppetry’, otherwise, he and Fu Chao would be digging until who knows when.

With the help of assistants, efficiency doubled!

As the sound of metal clashing rang out, golden lines appeared inside the cave.

These golden lines extended into the mountain.

"Follow this line and continue down!"

Li Yunjing, while sensing the concentration of ’Geng Metal Qi’ within the mountain using ’Geng Metal True Qi,’ ordered the ’Puppet Mechanism Beasts’ to dig in that direction.

Moreover, as the cave space gradually expanded, Li Yunjing could release more ’Puppet Mechanism Beasts.’

Behind each ’Puppet Mechanism Beast’ wielding weapons, they kept digging relentlessly, with efficiency as smooth as flat ground!

"Old Li, how come you have so many treasure artifacts?"

Seeing dozens of ’Puppet Mechanism Beasts’ all equipped with treasure artifacts, this scene truly stunned Fu Chao.

"Hehe! Acquired at the East Sea! Unfortunately, these weapons are not handy, affecting efficiency! When I have time, I’ll craft some hoe heads, pickaxe heads, and perhaps the efficiency of these ’Puppet Mechanism Beasts’ will be even higher."

Li Yunjing revealed a smile.

And while Li Yunjing and Fu Chao headed toward the mountain’s core, the battle outside neared its end.

Primordial Yang Dao Sect’s Master Zhu Yang fought two-on-one, the ’Red Flame Long Saber’ sweeping across, forcing the two Yin Mountain Sect demon cultivators into retreat.

"Jie jie jie... a Primordial Yang Dao Sect junior dares to be so bold here?"

At this moment, a black-robed elder stepped into the air, covered in surging demonic qi, clearly a Golden Core Realm Seventh Heaven demon cultivator!

"It’s Netherworld Ghost Sect’s Yinsha Old Demon!"

The two Yin Mountain Sect cultivators were delighted, quickly saluting.

"Useless, unable to handle a junior!"

Yinsha Old Demon snorted coldly, "I concealed my traces for greater opportunity but now, thanks to you two, I must prematurely reveal myself!"

Upon arrival, Yinsha Old Demon cursed the two elders of the Yin Mountain Sect.

"Senior is right in your reprimand! We are incompetent, causing you trouble, senior."

Wang Qian and Wang Kun’s faces turned blue then white, bending low and humbling themselves, even swallowing their pride as Golden Core cultivators, directly addressing someone of the same realm as senior.

Not that Wang Qian and Wang Kun wished so!

It’s just that Yinsha Old Demon was too fierce!

So awe-inspiring!

Even fellow demonic cultivators feared him somewhat.

"Yinsha Old Demon, do you dare intervene in our Primordial Yang Dao Sect’s affairs?"

At this moment, even Master Zhu Yang of the Primordial Yang Dao Sect saw this person and his face turned terribly grim, gritting his teeth.

At the same time, Master Zhu Yang secretly signaled those around him to retreat to prevent being suddenly struck by this old demon.

"Intervene? Hehe..."

Yinsha Old Demon laughed sinisterly, "This ’Profound Gold Divine Iron Mountain’ is a must for our Demon Dao, none of you orthodox cultivators will leave here alive!"
