In the frozen highlands, there are more demon goblins and demon minions, and demon minions are the same monsters as demon goblins, but because their levels are different, demon minions are level 33, so their names are somewhat different, and the experience is not very clear, after all, the lone demon minions last time were too close to the monster group, and we didn't dare to chase them.

Following the crooked road guided by He Tian, we really encountered some scattered demon goblins, but this number is not much, there are two or three people who are alone, we even started to be unrestrained when we fight, and directly charged over, facing this demon goblin is a knife, although the demon goblin in the vertiginous state will also teleport, but the rest of the attack we will give the circle remotely. It's a pity that we don't see any lonely boss-level demon goblins.

But even so, our upgrade is not slow, because the experience value of the monsters here has a fight with us in the River of Flames, although there are few monsters here, but the River of Flames is calculated according to the month, and here it is by the day, I don't know how many times the cost-effectiveness.

I've been working on this mutated fireball technique along the way. From what I've gotten from my data eye, this mutated fireball technique must have been centuries ago, when the first generation of humans appeared. It's a pity that only the skill of hellfire has been passed down so far, and the fireball technique has only been passed down with a huge burst, which ensures his attack range, but in terms of power, I think it should not be as powerful as this fireball with a tail.

What is it exactly? How should this be changed?

These demon goblins can't give me the magic structure of the mutated fireball, all of this needs me to explore slowly, even when I encounter a battle, it is they who attack, and I am observing, I know that these monsters are not a threat to our team, it is better to quickly study it thoroughly, so that not only can my fireball go to the next level, but for Chloe and Chastity, I can tell them the experience, so that they can strengthen their spell skills without detours.

"Why are they all fireballs, but there is such a big difference? One for scope, one for speed? Speed, yes, it's speed! ”

I suddenly remembered that the speed of the fire bomb technique has increased because of compression, and that kind of direct compression belongs to it, what if it is a spiral? Isn't the velocity up, and it works for this fireball, because the speed caused by the spiral makes it look like there's a tail behind the fireball.

I slowly changed the structure of the magic in my hand so that the fireball in front of me remained the same, adding a spiral structure to the advancing structure so that it could spin.

When the fireball came out, it didn't change on the outside, it was still a round ball, but the inner magical structure had changed for me.

"Go!"

I threw the fireball technique directly, this fireball technique is crooked and doesn't go in a straight line, it looks very funny, although the speed is there, but this accuracy is really worrying.

"Boom!"

The fireball exploded when it landed, but unfortunately it was still 5 meters away from the target I set, which was really a bit powerful.

"Uh, boss, please."

He Tian said pitifully in front of him.

"You say."

I'm still thinking that the fireball must be caused by the spiral structure not being structurally stable.

"That is, when your fireball is not well experimented, don't put it into the battlefield."

He Tian didn't want to be in the middle of a battle, and suddenly one of my fireballs hit his sadness, it was too dangerous.

"Don't worry, I'm not stupid and I'm not stupid, this is just an experiment."

I smiled and shook my head and continued my experiment.

"Look, there's a fence there."

After a few days of walking, we found a place surrounded by monsters on the outside, but in the middle was a fenced area, and it was impossible to see what was inside.

"Avila, can you see clearly?"

We had to turn to Avila, who had the best view.

"Well, there seems to be a sealing light curtain there, I can't see it clearly, I can only see that there is probably a vague figure inside, which looks stronger than He Tian."

After reading it very carefully, Avila said with a lot of certainty.

"That's right, this should be those captured barbarians, and I don't know what the monsters think, so they didn't kill them."

He Tian slapped his right hand towards his left hand, as if to confirm the news.

"Don't talk nonsense, what we need now is rescue, why didn't we kill, you can ask them if you save it in a while."

I gave up experimenting with the mutated fireball, and now the mission goal is in front of me, and I will talk about it when this matter is solved, although this spiral fireball has no eyebrows, but I can tell Avila about my experience later, so that she can also understand the spiral arrow.

······

"Investigate, on the left is a group of servants."

"On the right is a group of demon goblins, but behind them there is a huge contraption, and I don't know if it's a beast or a machine."

He Tian and Avila each reported the results of their close investigation.

"Okay, then let's attack the servant demons on the left first, Chastity, you use the War Tree Man to lure these servant demons over, and you can attack them."

For the task of seducing the Servant Demon, I handed it over to Chastity, after all, the Treant can be summoned again if he loses compared to his teammates.

"Smack!"

The War Tree Man is also a kind of monster in general, and his proximity naturally did not cause the active attack of the Servant Demons, but the whip of the War Tree Man directly blinded one of the Servant Demons.

After the War Tree Man finished this whip, he immediately began to retreat, not caring about the movements of the servant demon at all.

These servant demons are quite united, and naturally they came together towards the side of the war tree man, and in the process of pursuit, we found that there was a blue figure among these servant demons, and half of the servant demons were brown, and it seemed that it was a monster at the level of a leader or above. I didn't expect us to sneak attack, and we went directly to the highest guard here.

The speed of these servant demons is very fast, and the tree whip of the tree man is a long-range attack, but the tree man only took two steps before being surrounded by these servant demons.

This made us lose the ambush farther away, and we had no choice but to get up and approach these servants.

We were able to attack after a few steps forward, and He Tian also used a jump to quickly enter the battlefield, and the Charge Shield Strike was used continuously, knocking out the two servants.

"Vine entanglement."

"Bombardment!"

"Fireballs, guns!"

Our attack avoided the blue servant demon, and killed these ordinary servant demons first, what I didn't expect was that even a simple servant demon had more blood than the servant demon we encountered in the bloody hills, and we didn't care about it, thinking that it was just a little higher level, and at this time we didn't think about it at all.

It wasn't until we killed the rest of the Servant that when attacking the blue Servant, I noticed that the Blue Servant was not the leader of the Servant, but a Corrector - a strange Dark Gold Servant, its characteristics are extremely fast, no wonder, otherwise how could it be so fast to besiege the War Treeman.

It's a pity that their talents, if there was an Overseer in the middle, or if they were with the demon goblins over there, we wouldn't have raided so easily, this dark gold servant demon was so aggrieved that we were killed, but the loot given was a big disappointment, except for a necessary key, the rest was thousands of gold coins and a few bottles of potion, and not even a piece of equipment was exploded.

"It seems that this key is the one who opened this sealing light curtain."

Avila handed over the key to He Tian, and we moved on to the other side, a group of demon goblins were not worth mentioning, but in the chaos of the battle, one of the demon goblins took advantage of our inattention to the huge beast behind it.

When we got closer, we confirmed that it was a beast, called the Heavy Pressure Beast, a mutated beast that these monsters had specially domesticated in order to attack the city.

However, because there is only this one left, it is difficult to support it alone, and it will eventually die together with the Treants, after all, this full-level hellfire has not been carried by anyone in our team except me.
