"Takeru, are you really sure it's okay?" Looking back at what she had once caused, Emilia felt immensely emotional.

"Don't worry, it's a minor issue. However, the Black Serpent over there, though frozen, is still polluting the surroundings." Hearing her, Takeru's gaze turned toward a giant black serpent… the last of the Three Great Witchbeasts, the Vilest of Witchbeasts.

Thinking this, a massive fireball appeared out of thin air from Takeru and directly blasted the Black Serpent's location. After a huge explosion, both the Black Serpent and a large swath of earth beneath it were vaporized by the terrifying flames.

As for the tainted areas around the serpent, Takeru directly cast a giant purification skill. Soon, the toxins were all purified.

Due to continuously learning this world's magic, Takeru's previously learned healing and purification skills had surpassed the advanced level and reached the peak level, the only two peak-level skills Takeru possessed.

Arriving at the forest's center, Takeru saw many frozen elves. Casually touching one of the ice statues, Takeru could feel they were still alive, just in permanent ice-bound stasis.

"Lia, Betty, wait at the edge for a bit. I'll use my mana to remove the ice here later. If you're too close, you might be affected." Looking at Lia and the others, Takeru spoke softly.

"We understand, Takeru. Please be careful." Hearing Takeru, Lia and the others nodded obediently, then rode the giant eagle away from the center.

After their departure, Takeru used a bit of his own mana to levitate into the air. Then, he began preparing his mana.

Betty and the others, far from the center, soon sensed the immense and terrifying mana fluctuations from Takeru and watched his actions attentively.

Since Emilia used freezing magic, Takeru only needed to use reverse ice-binding magic to remove the ice here. The only trouble was that the mana Takeru released had to be stronger than the mana Emilia released back then.

But this was no problem at all for Takeru. After some preparation, mana from within Takeru's body quickly expanded, enveloping the entire Elior Forest.

"Release!" Sensing it was about time, Takeru opened his eyes, transforming his mana to eliminate the mana left by Emilia earlier. Takeru's internal mana reserves rapidly depleted.

In less than two minutes, the mana consumption exceeded ten thousand and was still rapidly decreasing.

Soon, as time passed, Emilia and the others in the distance noticed changes in the forest. First, the ice on the completely frozen trees began to melt, with green light appearing very conspicuous in the snowy world.

"Lia-nee, the trees are starting to recover!" Noticing this, Felt called out excitedly.

"Mhm!" Hearing Felt, Lia's eyes filled with joy. Betty, Ram, and the others worriedly looked at Takeru.

Though they knew Takeru's mana was immense, eliminating the mana here was also very difficult, and they worried Takeru might not hold on.

If not eliminated in one go, the area would freeze again, and the frozen people could be in danger. Of course, compared to the others' safety, Takeru was most important.

As for Takeru, although his mana was rapidly depleting, it wasn't a significant burden because his mana reserves were still over one hundred thousand. Five minutes of consumption had only used slightly over thirty thousand.

According to Takeru's estimate, consuming another twenty to thirty thousand mana would completely remove the forest's freezing.

Everything went as Takeru predicted. Another five minutes passed, and the forest's ice and snow completely melted. The frozen elves were completely freed and collapsed on the ground one after another.

Then, Takeru stopped releasing mana.

Sensing Takeru had stopped, the others quickly flew the giant eagle to Takeru's side...

"Takeru, are you alright?" Betty immediately asked, her blue eyes full of tension and concern.

"Don't worry, I could handle another Elior Forest!" Hearing her, Takeru said with a light laugh.

"Speaking of which, let's gather the villagers first. After a century of freezing, it's better to treat them a bit." Then, Takeru directly pointed at the elf villagers below.

"Mhm!" Hearing Takeru, no one had any objections. They began using their abilities to gather the relatively few ordinary elf villagers together.

Takeru then cast another group healing on them. Under Takeru's treatment, some adult elf villagers began to wake up.

"Everyone, I'm sorry!" Seeing her awakened kin, Emilia immediately apologized.

But everyone looked at Emilia with confusion. Their memories still stayed at over a century ago, when the Black Serpent invaded.

"Lia, I'll leave the rest to you." Seeing this situation, Takeru patted Lia's shoulder and said.

"I understand." Hearing Takeru, Emilia nodded seriously, then began to explain her identity to everyone, narrating how they were frozen and the changes in the outside world.

Faced with Emilia's sincere apology and partial explanation of Pandora's invasion, the villagers didn't blame her. Especially after learning Emilia's mother was Fortuna, they quickly accepted her...

Perceiving this from a distance, Takeru smiled slightly. He then continued mining the magic ore in the Elior Forest, casually killed a witchbeast resembling a snow ape, and stored it in his item slots.

The so-called magic ore is a blue crystal containing special mana. It can be used to forge weapons or armor, or for training mana and recovering mana.

Of course, this world doesn't utilize magic ore much, so it's somewhat a waste. If developed well, it could be applied in various fields. Perhaps it's also because magic ore is too rare.

Of course, Takeru didn't need to develop more uses. He only needed it for mana training. Having acquired a wealth of magical knowledge in this world, and with quite a few disciples, he knew not everyone would be very suited for Chakra Training, so this could be an additional option. 𝘧𝓇ℯ𝑒𝓌𝑒𝑏𝓃𝘰𝘷𝘦𝘭.𝒸ℴ𝓂

As for Nen, unless necessary, Takeru didn't plan to teach people from the main world from scratch.

The main world was mostly ordinary people. Training Nen would start too slowly and be very arduous.

For someone like Betty, Takeru could forcibly open their Aura Nodes to learn Nen. Betty could also master the basics of Nen in a day or two.

But for ordinary people, if Takeru forcibly opened their Nen, the result would likely be failing to learn Ten, leading to their Aura dissipating until death.

If done gradually, even with immense effort, they might not achieve results in a year. In contrast, other abilities might yield some small achievements.

Moreover, most importantly, if they truly wanted to learn Nen, they could first learn Chakra or mana basics, practice a bit, then switch to Nen, which is a good alternative.

With earth magic, peak mana control, and arguably infinite mana, Takeru's mining speed was incomparable to ordinary people, not to mention his shadow clone ability.

In one day, Takeru mined over half of the Elior Forest's ore veins, accumulating nearly ten tons of magic ore. Stacked together, it would be like a small mountain.

After mining this much, Takeru stopped, leaving the rest behind as this was sufficient.

After a day of conversation, Emilia basically informed everyone about the outside world. After discussion, they decided to stay in the forest for now. Seeing this, Takeru created a special barrier to protect the elves.

Then, Takeru and the others stayed for a few more days. During this time, something that pleased Takeru was that his left eye's Sharingan evolved from Three-Tomoe into Mangekyo Sharingan, all naturally progressing.

The new ability was also extremely powerful: time reversal, able to revert matter to its state three minutes prior.

Of course, currently Takeru's effective range was at most one kilometer, and the more matter affected, the greater the strain on himself.

Moreover, after using it once, there was a thirty-minute cooldown before Takeru could use it again.
