206: Advanced Cave Upgrade Voucher

Mu Feng had originally planned to show off his skills in this Secret Realm and see the full power of his Dragon Transformation.

But then he saw that there was only one Foundation Establishment Stage Puppet.

He immediately lost interest.

Moreover, this Immortal Cave didn't look very good.

It was too small.

He couldn't even fully transform there.

Bringing the two Little Lizards with him,

Mu Feng quickly entered the interior of the Immortal Cave.

The Immortal Cave space was slightly larger than the outside.

The lighting was also good.

As soon as Mu Feng entered, he saw the red upgrade voucher placed in the center of the Immortal Cave.

“Roar!”

Just as he was about to take it,

the giant tiger Puppet guarding the Immortal Cave discovered Mu Feng, the intruder.

With a roar, it charged towards him.

With his current strength, killing such a Foundation Establishment Puppet was effortless.

However, it was rare to encounter a sparring partner with decent strength.

Mu Feng decided to let the little fox gain some combat experience.

He couldn't let its excellent talent go to waste.

“Xiaoyue, go!”

After casually swatting the giant tiger Puppet away with a palm,

Mu Feng let the little fox deal with it alone.

He, on the other hand, walked towards the central position.

“Hmm, Little Lizard, you help watch from the side. If Xiaoyue is in danger, you step in and help.”

After thinking for a moment,

Mu Feng patted the Puppet Lizard's head.

He told it to help look after the little fox.

This would also foster the relationship between his two pets.

Then, he went and took the Advanced Immortal Cave upgrade voucher from the central position.

Inside the Immortal Cave,

after receiving Mu Feng's command,

the little fox immediately entered combat mode.

After a few days of growth,

it was now at Qi Refining Thirteenth Layer.

It was not far from the Foundation Establishment Stage.

It still had a good chance against a Foundation Establishment Puppet.

“Roar!”

The giant tiger Puppet in the Immortal Cave was sent flying by Mu Feng's punch, but because Mu Feng held back, it didn't suffer much damage.

Now, seeing Mu Feng trying to lay claim to the item it was guarding,

it pushed off with its two legs, ready to continue charging at Mu Feng.

However, as soon as it got up, it found its body solidified.

It was the little fox next to it, who had used its Petrification Spell.

After casting Petrification,

the little fox swung its three tails and instantly appeared on the giant tiger Puppet's face.

With two sharp claws, it immediately scratched several white marks on the giant tiger Puppet's face.

Compared to speed,

the little fox's attacks were weaker.

Especially its Physical Body attacks.

Fortunately, its Spells were powerful, which compensated for its weaker Physical Body attacks.

After several sharp claw attacks,

it directly disfigured the giant tiger Puppet's face.

The damage wasn't high, but the humiliation was extreme.

After a long struggle, the giant tiger Puppet also broke free from the Petrification's restraint.

It opened its mouth, and a ball of energy immediately shot towards the little fox's body.

Facing such a sharp attack,

the little fox dared not take it head-on.

Its body flashed,

and it dodged the fatal energy blast.

Then, it activated its Illusory Transformation.

It became invisible and entered the space, waiting for an opportunity to strike. The giant tiger Puppet lost its target.

It could only thrash around aimlessly.

“Not bad.”

Mu Feng watched the battle for a while.

He felt that the little fox indeed had combat talent.

It knew how to use its advantages to attack the opponent.

As expected,

when the giant tiger Puppet's energy was depleted, that would be the little fox's chance to win.

Seeing this,

Mu Feng shifted his attention to the Advanced Immortal Cave upgrade voucher in his hand.

Unlike the previous Intermediate Immortal Cave upgrade scroll,

the Advanced Immortal Cave upgrade voucher was simpler.

It was just like a piece of paper.

Mu Feng focused his attention, and the information of the upgrade voucher appeared before his eyes.

【Advanced Immortal Cave Upgrade Voucher: After learning, you can view the Materials required to upgrade to an Advanced Immortal Cave.】

【System Reminder: Do you want to learn?】

“It seems I still need to find the Materials myself to upgrade…”

Although the Advanced Immortal Cave upgrade voucher and the Intermediate Immortal Cave upgrade scroll looked different,

their effects were the same.

This made Mu Feng a little disappointed.

He had originally thought that this upgrade voucher could directly upgrade the Immortal Cave.

It seemed he had thought too much.

In this Cave World, everything required the consumption of resources.

It was impossible to achieve a permanent solution.

Although he was a little disappointed, Mu Feng still clicked to learn.

【System Reminder: Learning successful. You can view the Materials required for the upgrade on the Immortal Cave panel.】

Opening the panel, Mu Feng clicked into the 【Immortal Cave】 page.

【Current Immortal Cave: Intermediate Immortal Cave】

【Effect: Immortal Cave Spiritual Qi density increased by 200%, Spiritual Field opened for planting Spiritual Plants and Spiritual Trees, Spirit Gathering Array added, Insect Room and Defensive Spell Array opened.】

【Next Rank: Advanced Immortal Cave】

【Upgrade Requires: void spirit stone 1/5, dream stones 0/3, Any Millennial Spirit Wood 1/5, wood Spirit Orb 0/1, Fire Spirit Orb 0/1, Gold Spirit Orb 0/1, Water Spirit Orb 0/1, Earth Spirit Orb 0/1, Jade 0/10, High-Grade Spirit Stone 11/20, Mid-Grade Spirit Stone 0/300, Low-Grade Spirit Stone 16500/50000】

【Upgrade Effect: Immortal Cave Spiritual Qi density increased by five times, new Immortal Cave space opened, Teleportation Spell Array added, Immortal Cave scale expanded, can name the Immortal Cave.】

“Ah, this…”

“Does it have to be this exaggerated…”

After reading the Materials required for the Advanced Immortal Cave upgrade,

Mu Feng was completely stunned.

Not to mention other Materials,

the total number of Spirit Stones alone would be 100,000.

He had originally thought he had a lot of Spirit Stones.

But he didn't expect that it only met a little more than a quarter of the requirement.

Whether it was High-Grade Spirit Stones or Mid-Grade and Low-Grade Spirit Stones, he didn't have enough of any of them.

As for the other Materials,

Mu Feng only had one void spirit stone obtained from the Heaven Crystal Ant.

Everything else was completely missing.

Oh, and he also had one piece of Millennial Spirit Wood.

That was the soul nourishing wood he had just obtained.

However, Mu Feng was reluctant to use it to build an Immortal Cave.

His Millennial soul nourishing wood had other important uses.

As for the millennial golden fruit tree he had picked earlier, Mu Feng had cut it down.

However, it was not Millennial Spirit Wood.

The cut wood could only be used as ordinary wood.

Fruit trees and Spiritual Trees were still different.

“void spirit stone, dream stones, Millennial Spirit Wood, five Five Elements attribute orbs, Jade, and a huge amount of Spirit Stones.”

“Alright, I'm back to being a pauper again.”

Mu Feng had originally thought that the Spirit Stones he had were enough for him to splurge for a long time.

He had hoarded many Materials and didn't plan to sell them.

He didn't expect that upon checking, he was still missing so much.

It was truly a return to square one.

It was too difficult to escape the status of a black slave and achieve financial freedom.

Indeed.

Wealth, companions, Spells, and land, wealth, companions, Spells, and land.

There was a reason why wealth was ranked first among the four major principles of cultivation.

While Mu Feng was looking at the Materials required for the Immortal Cave upgrade,

the battle on the little fox's side was also nearing its end.

Although this giant tiger Puppet was a Foundation Establishment Puppet,

its mobility was too poor.

Its speed was simply not on the same level as the little fox's.

Although the damage was like scratching an itch,

scratching it enough times was still effective.

After being petrified once again,

the giant tiger Puppet was directly dismantled by the little fox.

“Ying ying!”

Successfully defeating the giant tiger Puppet,

the little fox was very happy.

The joy of fighting above its Rank made it extremely excited.

“Not bad, not bad.”

Mu Feng stroked the little fox's fluffy tail.

He praised it.

Being able to fight above its Rank showed that the little fox indeed had combat talent.

Once he refined the Spirit Nurturing Pill,

and raised its Rank further,

it could help him in battle.

Having defeated the giant tiger Puppet,

and taken the items from this Secret Realm,

Mu Feng was about to leave.

Suddenly, a red prompt appeared before his eyes.

【Did you not notice that there was something else on the giant tiger Puppet?】

Something on the giant tiger Puppet?

Seeing the prompt,

Mu Feng was stunned.

He had just been busy praising the little fox and hadn't noticed anything on this Foundation Establishment Puppet.

However, since the System prompted him,

it meant he must have missed something.

Immediately, Mu Feng squatted down and began to search for items on the giant tiger Puppet.
