This dungeon has mushrooms growing on it.

Chapter 4 4. Magic Crystal
The mushroom garden is backed by rock walls on both sides. These rock walls look like skeletons gnawed by giant beasts, and the dark gray rock surface is covered with honeycomb-shaped erosion holes.

Dark purple crystal clusters condensed in certain depressions, scattered throughout the entire rock wall, and the concentration of magic power around these amethysts was always higher than at other locations.

The so-called mining area is where these amethysts are collected.

Although inserting this purple crystal into the soil will not directly turn into nutrients, it can attract the free magic power in the surrounding air to gather and improve the efficiency of mycelium in collecting magic power.

There are many Puji equipped with the Chitin Shell skill in the mining area. They form a thick shell on the mushroom cap and then use it to chisel out the crystals in the rock wall.

To be honest, the shell of the skill is only level 4 and the hardness is not enough, so the mining efficiency is quite low. Puji can easily be killed by its own shock. But the conditions are limited, so it is good enough to be able to mine it.

Inanna set her eyes on a fist-sized amethyst that she had mined, and held it tightly with her short legs.

"What are you doing?"

"Lin, Lin Jun?"

The pink Puji trembled violently and tripped over the purple crystal under her feet.

"Don't talk in your head all of a sudden..."

"Do we have other ways to communicate? Get used to it soon."

Inanna thought about it and it was true, but she still felt that she might not be able to adapt to someone talking in her head anytime and anywhere...

"You have so many magic crystals here." Picking up the purple crystal again, Inanna couldn't help but sound excited.

"Magic crystals? You mean these amethysts used to fertilize the fields?"

"Fat...fat field?"

A green-capped mushroom jumped out and used its short legs to lift up the cap of a large mushroom nearby. Underneath it was a purple crystal half-stuck in the soil.

"You, you, you actually used magic crystals to fertilize the fields?"

"if not?"

"This is magic crystal! This is magic crystal that can be used to make magical items, as the base of a magic circle, and even small pieces can be used as materials for casting spells! How can it be used to fertilize the fields?"

Inanna looked heartbroken, making Lin Jun feel like she was wasting a gift from heaven.

"Have you forgotten this is a dungeon? But it does have other uses besides fertilizing the fields."

A tentacle made of mycelium stretched out from the bottom of the mushroom, activated the skill [Entangle LV3], rolled up a piece of purple crystal half the size of a palm, and tied Puji and the magic crystal together.

Then, a steady stream of magic power poured into the magic crystal, and the magic crystal changed from dull to shiny, and then from shiny to sparkling. The excessive magic power inside caused the entire magic crystal to be in an overloaded state.

When cracks appeared on the magic crystal and it let out a mournful cry of being overwhelmed, Puji jumped wildly onto an open space with the magic crystal.

boom--

exploded.

The aftermath of the explosion caused Inanna to fall again.

"It's very powerful, right? This thing is very useful against monsters."

Rolling to the ground, Inanna didn't know what to say.

A C-grade magic crystal, which could be used as the main material for a silver-level adventurer's staff with a little processing, was treated as a disposable item in front of her eyes, releasing an explosion with a power equivalent to that of a LV4 level Pyroblast.

Even the most ignorant upstart in the Federation would not waste these precious magical materials like this!
You know, even her own magic wand is only inlaid with a B-grade magic crystal.

"By the way, you haven't told me what you want the magic crystal for."

The sudden return to the topic made Inanna, who was still cursing Lin Jun for being a spendthrift in her heart, unable to react for a moment, and she directly stated her purpose:

"I want to use it to cast a spell."

After saying this, Inanna felt guilty again, because she didn't know whether Lin Jun would regard the ability to cast spells as a threat. If Lin Jun felt that she was a threat, her life would be in danger...

"Oh? Didn't you say you can't cast spells after turning into a Pooji?"

Lin Jun didn't seem to consider the threat at all, and his words were full of curiosity.

Inanna, secretly relieved, quickly explained, "Just trying it out. Perhaps using the magic crystal to cast a spell can circumvent the limitations of Puji's body."

"Then try it."

Another tentacle stretched out from under the mushroom, swept up the magic crystal next to Inanna, and stretched it towards her. Faced with the sudden approach of the tentacle, Inanna instinctively took two steps back, but was still entangled, and the magic crystal was tied to the top of her mushroom cap.

"Be careful, these tentacles are very fragile, don't break them."

After all, it is a stolen skill, and if you use it forcibly with mycelium, you can't expect it to really bind tightly.

After hearing this, Inanna didn't dare to move and focused her energy on casting a spell - Glimmer, a spell that even an apprentice could easily cast.

A ball of orange-yellow light appeared above Inanna's head, flickering as if the magic power that maintained it was unstable.

After flickering for a while, Inanna seemed to have found the trick and the brightness finally stabilized.

"It worked! It really works!"

Inanna was so excited that she actually jumped up on her short legs.

Snapped--

The bound tentacles broke instantly, the magic crystal fell to the ground, and the glimmer magic was extinguished - the mycelium tentacles were really very fragile.

"Hug, sorry..."

Lin Jun didn't care about the wasted mycelium at all. All his attention was focused on Inanna's spell.

"Try casting it again now."

"It can't be released without the magic crystal."

"It doesn't matter if you fail. Just let it go. I'll see if there's any difference."

have a look?

Inanna didn't quite understand what Lin Jun meant, but she still tried to cast the glimmer spell on her own.

Then, unsurprisingly, it failed, just like she had tried countless times before.

But Lin Jun, who had been observing her, saw more.

【Magic Perception LV4】

This was taken from a magic vine called Noctis's Whiskers that originally lived in the mushroom garden area. They rely on magical perception to find prey and then strangle them with vines. It is worth mentioning that the entanglement skill was also obtained from them.

Although these magic plants are of a high level, they cannot move and are no different from food in Lin Jun's eyes. They are now extinct in this area.

Lin Jun felt a little regretful about this. Both skills of Noctis's Whiskers were quite practical. However, at that time, he was only thinking about getting a piece of land and didn't think too far ahead. Otherwise, he could have left some seeds and raised them like the rolling beetles and slimes in the breeding area, and slaughtered them regularly to extract their skill proficiency.

In the magical vision, Lin Jun observed that the flow of magic power when Inanna cast the spell was indeed smooth in the initial stage, but the energy flow was blocked at each node and could never form a complete closed loop, as if the way she cast the spell was wrong.

Inanna had just used the magic crystal to cast the glimmer spell, so it was impossible that her casting method was wrong.

In Lin Jun's opinion, this is more likely due to the different body structures of humans and Puji - simply put, the hardware and system do not match and cannot run.

The magic crystal is an independent environment that can better match the way these magics work.

It feels a bit like the fact that you can only use the corresponding skills after you transform the Pujis.

"So can you use other magic now?"

Lin Jun knew that she was a dual-element level 4 mage, and he also wanted to see more spells.

"Um, I'm afraid I need more practice. I'm not very familiar with using my body to output magic power. Also, this magic crystal has not been polished and some cloudy areas inside will interfere with casting. I need to get used to it."

"Turbid? The purer the magic crystal, the better?"

Lin Jun really had no idea about this. He only knew that sticking it in the soil could gather demons. He thought some of the different effects were just a matter of size. As for using it to self-destruct... its purity didn't seem to matter.

"Of course. It's said that Archmage Zorya's staff is inlaid with a completely pure S-grade magic crystal. Any spell cast through that wand will be tripled in power!"

"S-level? There are different levels... Wait a minute."

After a while, while Inanna was puzzled, two Puji came to her together, carrying a large piece of crystal clear magic crystal.

"A...A-grade magic crystal? And it's the size of an arm!?"
