I, the villain, trained the loser into a dark boss

For the half-orc maid who once lived in the System family like a slave, she is strong enough to support herself, and has the freedom that the System family is willing to give her. In the eyes of outsiders, it is impossible to forget the past. The present moment may be her best choice.

Frankly speaking...

She came here to persuade Yi Aier... to step out and become a true "independent adventurer". The important thing is the word independence.

But now...

"Although she is really strong now, even strong enough to make many adventure teams go crazy..."

"It seems understandable. From our point of view, it is difficult for her to live for herself, but for her..."

"Living for that 'young master' must be the meaning of her life."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"This Flame Dragon...well, is this what it is?"

Yi Aier uncovered the information about the Flame Dragon BOSS in the Burning City. This was an exclusive secret from the White Castle, and it was extremely rare in the entire Adventurers Association.

"The reason why we need a very powerful ice-type Holy Shield is because of the special characteristics of the burning city where this flame dragon is located..."

The Burning City is just as its name goes. Of course, Yiel also knows that according to her young master’s analysis, there is no underground city in the world that is “not as good as its name”.

In this underground city, there are natural grease-like flammable substances on the ground. Therefore, the entire dungeon will be more critical to explosions and burning than other fire-attributed dungeons.

As the BOSS, Yanlong has a skill that naturally takes advantage of the terrain, and that is its tail with its own burning flames.

After entering, as long as it wakes up, there is no way to control it by force. The flame at its tail will touch the grease on the terrain and burn instantly.

"Hmm... If it's just the burning of the field, it should also be achieved through long-range skills... Oh, is this the reason why it can't succeed?"

Turning to the next page, Yiel understood why this move was not feasible.

However, it was still a flame dragon that was "not good at flying". During the entire battle, no flying skills were observed on it. In other words, it is still very timid and will always hide behind the burning flames in the field to attack. The archers who can restrain the flying dragons now have a blank slate, because they still need to resist in order to pass the long corridor of the dungeon BOSS room. The bow and arrow that held the flame didn't even have much damage left.

"Then, according to the "Rules to Remember in Killing the Fire Dragon"...also known as the "Charmander Revenge Strategy", it should be like this..."

Yiel temporarily simulated a set of his own processing methods on the scratch paper.

Her handling method did not even give the people behind her a chance to "attack". She planned to go on alone and finally use her shield to physically knock Yanlong to death.

When the clock struck twelve, she stopped writing and looked up at the moonlight outside the window.

"It's...already so late? It turns out...studying things in dungeons can also make people forget time..."

Looking at the notes under the candlelight, Yi Aier suddenly remembered that every night, she saw the young master taking notes through the crack in the door.

Now she is the person sitting in the room.

but……

The scenes she had seen before would never happen again.

She looked back at the closed door of the room and sighed deeply.

"Actually... Yi'er knows better than anyone else that you will not come back, young master..."

"Yiel is just... just completing the tasks you left behind, tasks that will not be updated, tasks that have no explanation, tasks that will eventually end..."

"Deceive yourself over and over again... You didn't abandon Yi Aier by means of 'death', which proves that you definitely need Yi Aier now..."

"...That's all."

Chapter 390: Crusade on Easy Difficulty

Burning city, level 39.

The skilled White Castle team reached the end of the 39th floor with almost no consumption. A mature adventure team will usually check their respective status before entering the BOSS room and confirm the fighting method after entering.

"Well... the supplies are very complete, and the back row is in good condition. After entering, keep this position for the time being... Then... Yi'er?"

Peflan finished counting, stood in the middle row, and looked at Yiel who was standing in the front holding a shield.

Yiel turned her face sideways and nodded.

"no problem."

"Then let's set off—"

"OK."

This battle is also a unique encounter for experienced adventurers in White Castle.

After entering the house, they saw the true meaning of Yiel's "unsolvable frost"——

Yiel, who had been standing in the front row since entering the room, inserted the shield into the grease-like burning object on the ground without any hesitation.

Immediately afterwards, the most difficult part of this dungeon began. The moment she just completed this action, a violent "explosion" and "burning" swept across from the place where the Flame Dragon was sleeping.

"Su Bing array·spread out."

The black maid, her tail swayed in the hot wind, just because it was blown by the wind, making every hair move with the wind.

She was actually very determined, with her ears erect, like a firm compass amidst the explosion and hot wind.

Wow——

The moment the shield came into contact with the grease-like substance, the substance on the ground was directly "frozen" by her, as if freezing magic was released on the vast lake, freezing the ground hundreds of meters in front of her. Severely dyed ice blue.

On the crimson-red BOSS level of the Burning City, where every brick and tile seemed to be burning, and everywhere was filled with "explosions", a beautiful ice-blue flower bloomed on the ground. For example, the snowflakes that just fell from the sky cling to the ground, forming a formation called "snow".

Using the so-called "shield" and "defense", he controlled the entire scene with a cold taste. The adventurers present were all experienced, but this was the first time they had seen the Shield Master operate like this.

As the BOSS, Yanlong will not stop there.

It was fully awake and could hear the muffled sounds coming from its mouth.

It ignited the flames on its tail fiercely, and in order to recover from the unfavorable start of not igniting the entire grease-like ground, it increased its firepower.

Its flames are still expanding crazily, with the momentum to completely destroy Yiel's ice flowers.

"Ice wall."

Yiel did not give this chance, she said the most basic defensive measure.

What is displayed in front of everyone is not just a simple "ice wall".

The ground with six snowflakes as the core extends from the center to the corners of the snowflakes. A huge but extremely transparent ice wall is erected at each corner.

She expanded the "ice blue" on the ground into the air in a three-dimensional manner, forming an existence similar to a city wall.

The flames that spread and burned were blocked by such a wall, and spread flat along the direction of the walls that expanded to both sides.

"Boss, this... what is this? I... we should only need a Holy Shielder with an ice wall... that's enough?"

"It's different from the ordinary straight upright ice wall. The angled ice wall seems to have built a maze tailor-made for the burning flames on the opposite side..."

Pevlan was a little surprised.

At least……

A few months ago, when she picked up Yi'er and took her to the capital to find someone, she didn't have such a strong ability at all.

Now, not only is she as decisive as Frost and does not allow anyone to change, but the ability and judgment of an adventurer she displays are also as insoluble as Frost.

Decisive and correct.

"The contact surface between them and the ice wall has been extended, making the contact surface of the burning flame larger. It will not be breached at a certain point like the previous ice wall..."

At this point, Pevlan realized a problem, something she felt the little maid with animal ears might ignore.

"Wait a minute, Iel, if you freeze the grease on the ground and erect it as an ice wall—"

Just as he said these words, everyone's ears already heard a slight explosion coming from the ice wall.

Yiel's ice wall is not simply made of water. She deliberately froze the grease-like substance under her feet. It looks particularly clear, but it is easier to ignite.

"Don't worry, nothing will happen."

Yiel, who was standing in front of Peflan, replied. Peflan looked at her fingertips pressing on the shield, which were already coated with a thick layer of frost.

She was using her defensive magic like crazy.

"In other words, this is how we can ensure that we can kill this little fire dragon without any risk."

The cracked ice replenished at a completely unpredictable speed, and the entire snow-flaked ice wall seemed to be pumping grease-like substances on the ground into the wall before burning them, consuming it like crazy.

"You...you want to..."

"Wait a moment and you can attack."

"Boss!? Isn't it time to attack now? No matter how you look at it... no matter how you look at it, it's the most appropriate time!"

"If I remember correctly, Miss Pevlan, you promised me that until I block the first wave of burning on the other side, you will continue to advance along the ice wall. You see, the other side is still exerting force, so it is not over, right? "

There was no smile on Yi'er's face, but her tone was much more "confident" than before. She seemed to be sure that she could win the entire battle on her own.

Pevlan understood...

Yi Aier wanted to use the fire on the opposite side to cooperate with her ice wall to suck up all the grease on the ground!

This is a truly risk-free attack. After all, in such a "crazy burning city", even if there is an ice wall blocking the flames in front of you, any spark falling on the ground will cause a massive explosion.

To accomplish this, a continuous supply of energy is required - this requires strong endurance and physical fitness. In addition to continuous energy supply, it also requires precise control of heat.

Yiel did it.

A fighting method that had never been seen before, a fighting mode that no one had ever tried, and a fighting strategy that no one had ever dared to apply were displayed under her hands like clouds and flowing water.

The Flame Dragon on the opposite side didn't seem to realize that this was a huge trap, and was still heating up its own flames and burning continuously.

Her hand rested on the shield, and the wagging of her tail became weaker and weaker. The "hot wind" brought by the opposite side was disappearing little by little, and then, her animal ears began to sway to both sides to match the previous one. Completely different direction.

Her ice wall gradually took control of the situation.

Then--

"I've done what I should do. Next, please start--"

When the burning on the opposite side could no longer ignite any drop of the grease-like ground, Yi Aier turned around and, as if she had finished a very delicious dish, extended her hand to invite the other people in the White Castle.

Chapter 391 An Unsuccessful Invitation (3k)

"Is the person sitting there the White Castle? Did they recruit that... Flame Dragon Killer?"

"It's not surprising to recruit the Flame Dragon Killer, right? After all, the maid in black will gladly accept any job related to the Flame Dragon."

"The Flame Dragon Killer is indeed worthy of its reputation. Who would have thought that she could turn the tables when the terrain was completely disadvantageous and the opponent had all the advantages?"

...

Yi Aier felt a little strange when listening to the words around her.

She rarely came into contact with the Adventurer's Association. She usually went to the Adventurer's Association to look through the commissions and the appearance records of the nearby Flame Dragon BOSS.

In the past...

If Will hadn't brought her in for dinner, she wouldn't have walked into the Adventurer's Association.

Sitting here, she could hardly understand what the adventurers nearby were saying, so she could only eat delicious barbecue, delicious fried banana skewers, delicious grilled fish...

She looked at the empty table. The people of the White Castle raised their glasses to toast the tables of the Adventurer's Association for this celebration banquet.

So...

She was the only one left here "watching the table".

Thinking of this, Iel took a bite of barbecue. This was the first time she had eaten such "unhealthy" fried meat in the past month.

"It's surprising... It's not delicious at all."

She used to like it very much, and because Will liked it very much, she also learned how to make barbecue better.

But now, the food in front of her no longer tasted the same as before.

"Hello, Flame Dragon Slayer! Are you listening?"

A voice seemed to be calling her in the noisy voices next to her.

"Hmm...?"

She raised her head, and a dungeon adventurer who looked more "luxurious" appeared in front of her. There were three men and one woman in the group, one of whom was wearing a huge witch hat. Iel recognized him at a glance because of Leah.

One of the men was blond, and his descent should be half-elf. Because he had inconspicuous pointed ears. Iel learned this from Treya.
