118: Sell ​​materials and upgrade the cave

Closing the chat window.

Mu Feng began to sort through the items he had obtained from this Great Secret Realm.

First, naturally, was the spirit eye tree.

He hadn't dared to examine it closely when he was in the Great Secret Realm.

Mainly because its Spiritual Qi was too immense.

One careless move could attract powerful Yao Beasts.

Now that he was back in his Immortal Cave, he could finally take it out and examine it carefully.

“The Spiritual Qi is indeed rich!”

As soon as Mu Feng pulled the bluestone pillar out of his Storage Ring, the Spiritual Qi concentration in the entire Immortal Cave immediately increased by several levels!

“Excellent!”

“With this spirit eye tree, I can save a lot of Spirit Stones used to activate the Spirit Gathering Array in the future!”

Mu Feng was excited.

【You can't save it. The spirit eye tree also needs to grow in a place with rich Spiritual Qi. Otherwise, once its Spiritual Qi is depleted, it will become a useless dead tree!】

“What do you mean?”

Looking at the red prompt that suddenly appeared.

Mu Feng was a bit confused.

What did it mean that it needed to grow in a place with rich Spiritual Qi?

Could it be that the spirit eye tree couldn't absorb the Spiritual Qi it released itself?

【It's simple. You can think of the spirit eye tree as a Spiritual Qi purification and conversion device. Its function is to absorb Spiritual Qi into the tree and then purify and release the absorbed Spiritual Qi.】

【If the Spiritual Qi absorbed by the spirit eye tree is insufficient, it will still release Spiritual Qi, but this will greatly damage its physiological functions, and over time it will die.】

“So, this spirit eye tree is alive?”

“I understand.”

Mu Feng nodded.

He finally understood why this stone pillar was called a tree.

Because its function was similar to that of a tree.

Absorbing sunlight (Spiritual Qi), then photosynthesis (purifying Spiritual Qi).

“Then, in that case, don't I still need to plant it in the herb garden?”

“No wonder it had roots underneath. So it really is a tree!”

Mu Feng had been puzzled when he first saw it.

At the time, he thought it was called a tree because it had roots.

Now it seemed it was originally a tree.

It was perfectly normal to have roots.

Alright then.

It seemed saving Spirit Stones was impossible.

“By the way, you just said that the spirit eye tree purifies the Spiritual Qi after absorbing it.”

“Then, if I activate a larger Spirit Gathering Array in the future, will the Spiritual Qi it releases be even richer?”

Mu Feng was suddenly excited.

Because the Spiritual Qi currently released by the spirit eye tree should be absorbed from the central area.

He knew the Spiritual Qi in the central area was higher than his Intermediate Spirit Gathering Array.

But it was definitely not comparable to an Advanced Spirit Gathering Array.

That is to say, if he had enough Spirit Stones to activate an Advanced Spirit Gathering Array in the future.

Then the Spiritual Qi released by the spirit eye tree would be even richer than it was now!

【Theoretically, yes.】

Indeed!

Mu Feng was overjoyed.

If that were the case.

As long as he had Spirit Stones in the future, he would never have to worry about insufficient Spiritual Qi purity.

This item could accompany him all the way to Foundation Establishment, Core Formation, Nascent Soul, Soul Transformation…

In the short term.

It seemed like a loss that the spirit eye tree couldn't save Spirit Stones.

But in the long run, it was a huge gain!

After all, if the spirit eye tree only had its current Spiritual Qi purity.

He might only benefit before Foundation Establishment and Core Formation.

Once he reached Core Formation, the spirit eye tree's Spiritual Qi would gradually weaken.

Now it was different.

As long as he had Spirit Stones, he could always ensure that the Spiritual Qi purity in his Cultivation area was always the best!

“Excellent!”

“Rounding up, it seems like an even bigger gain!”

Mu Feng was beaming with joy.

He walked into the herb garden with the spirit eye tree.

He chose a spot near the main hall and planted it.

Back in the main hall.

Mu Feng placed a hundred Spirit Stones into the Spirit Gathering Array.

Now that he understood the spirit eye tree's operation process.

The Spirit Gathering Array could not be stopped.

After activating the Spirit Gathering Array.

Mu Feng glanced at the wooden barrel next to the Spirit Gathering Array.

The changes in the insect eggs were not significant.

Perhaps it was because the Spirit Gathering Array here had stopped after he left.

Or perhaps it was due to the three-to-one time ratio.

It seemed like a long time had passed for him in the Great Secret Realm, but in reality, only one day had passed outside.

It was normal for the insect eggs to show no movement.

He would check again tomorrow.

Now with the spirit eye tree.

The Immortal Cave's Spiritual Qi, both in terms of concentration and purity, was several times what it was before.

He believed it wouldn't be long before these insect eggs hatched.

Speaking of hatching.

Mu Feng remembered he also had an egg to hatch.

Hmm, he'd put it in the herb garden for now.

Closer meant more abundant Spiritual Qi.

After dealing with the spirit eye tree.

Mu Feng also transplanted the seeds of the Spiritual Plants and Spiritual Grasses he had obtained in the Great Secret Realm into his own herb garden.

After watering them.

Mu Feng also harvested some mature Spiritual Grasses that he had planted earlier.

This batch of Spiritual Grasses was what he had prepared to refine Star Light Pills.

He would refine them along with the Foundation Establishment Pills he would make later.

Anyway, he already had the Materials for both.

But before Alchemy, he still needed to process the Yao Beast Materials on him.

Exchange those that could be exchanged for soul, exchange those that could be exchanged for soul and essence of vegetation.

Those that couldn't be exchanged for anything would be exchanged for Spirit Stones.

The auction was about to begin.

It was said that mysterious items would appear.

Mu Feng didn't know what good things would appear.

However, it was best to prepare more Spirit Stones.

Lest he encounter something he desired.

But then not have enough Spirit Stones, that would be embarrassing.

Opening the Transaction Channel.

【Seller: Mu Feng.186】

【Item: Quan Quan Bear Fur】

【Demand: soul】

【Inventory: 1】

.....

【Seller: Mu Feng.186】

【Item: Bear Paw】

【Seller: Mu Feng.186】

【Alternative: essence of vegetation】

【Inventory: 4】

...

Mu Feng sold most of the Yao Beasts on him.

The remaining ones were all high-value items.

For example, Monster Strength Eagle feathers, Giant Centipede legs.

Mu Feng planned to auction these Yao Beast Materials with special Attach attributes after the auction started.

This way, he could maximize his profits.

All of Mu Feng's Materials were from Qi Refining Peak Yao Beasts.

As soon as they were uploaded to the Transaction Channel.

Everyone was shocked by his lavishness.

“Good heavens, Senior Mu Feng has gone crazy. All the Yao Beast Materials sold in the Transaction Channel are from Qi Refining Peak Yao Beasts.”

“How ruthless! I just took a look, there are at least five of them!”

“Who has soul? I'm willing to buy it at a high price with Spirit Stones!”

“soul? What is that? Are you sure it's soul and not Qi?”

“It's soul. I just tried to trade with Qi, but the trade failed.”

“Ah? Are these two different things? I thought Senior Mu Feng made a typo.”

“So, does anyone know what soul is?”

“I'm only Qi Refining Rank five, you're asking me?”

......

Mu Feng didn't know that he had once again shocked everyone.

After uploading his Yao Beast Materials.

Mu Feng conveniently searched for marble.

He was now only ten pieces of marble short of gathering all the Immortal Cave upgrade Materials.

It was as he expected.

marble was not hard to find.

In the end, Mu Feng spent five Spirit Stones to gather the remaining marble.

At this point.

All the Immortal Cave upgrade Materials were gathered.

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

【Current Immortal Cave: Ordinary Immortal Cave】

【Effect: Immortal Cave Spiritual Qi concentration increased by fifty percent, Spiritual Fields opened for planting Spiritual Plants and Spiritual Trees, Spirit Gathering Array added.】

【Next Rank: Intermediate Immortal Cave】

【Upgrade requires: marble 50/50, Nanmu 30/30, Sand 100/100, gold 10/10, wood spiritual energy 1/1, fire spiritual energy 1/1, Gold Qi 1/1, Water Spiritual Energy 1/1, earth spiritual energy 1/1, Spirit Stone 1498/1000】

【Upgrade effect: Immortal Cave Spiritual Qi concentration increased by two times, new secret room opened, Immortal Cave defensive array added.】

【System Reminder: Materials have been gathered. Do you want to upgrade the Immortal Cave?】

“Upgrade!” Mu Feng nodded.

Starting tomorrow, all Immortal Caves would be open.

At that time, both humans and Yao Beasts could enter other people's Immortal Caves.

His Immortal Cave had too many treasures, so upgrading the Immortal Cave was imperative.

With a defensive array, it would be much safer.

“Rumble!”

As all the Immortal Cave Materials were deducted.

The entire Immortal Cave where Mu Feng was located began to vibrate violently.

Because he had one upgrade experience.

Mu Feng was relatively calm.

At this moment, he was more excited about the appearance of his new Immortal Cave.

This upgrade took a bit longer than the last one.

It lasted for about five minutes.

The vibration of the entire Immortal Cave finally ended.

【System Reminder: Immortal Cave upgrade complete. Current Immortal Cave Rank is Intermediate Immortal Cave!】

A dazzling white light flashed.

When Mu Feng opened his eyes again.

The entire interior of the Immortal Cave was completely new.

The area was two or three times larger than before.

The formerly rough ground was covered with smooth marble.

It felt very comfortable to step on.

In the future, when something happy happened, he could directly slide and kneel in the living room to celebrate.

The Immortal Cave walls were upgraded again.

The walls that he had damaged last time were also repaired and became even harder.

The overall appearance also became smoother and smoother.

The bed and table also underwent a huge transformation.

They changed from stone to Nanmu tables and beds, inlaid with gold.

The main theme was luxury.

The upgraded Immortal Cave gave Mu Feng the intuitive feeling that a bare shell house had become a fully furnished house.

It looked much more pleasant.

Of course, the place he lived in had to be comfortable.

In addition to these external changes in the main hall.

A new secret room was opened not far from the original herb garden.
