Spellcasting is a permanent addition and my skills are all forbidden spells.

Listening to the movement in the factory building, Lu Cheng was a little surprised.

In the factory, muffled thumping sounds could be heard from time to time, occasionally accompanied by the roar of monsters.

Lu Cheng sniffed the tip of his nose and smelled a faint smell of rubber.

In the factory, there is probably a level six rubber monster!

Lu Cheng's eyes lit up.

For him, this is great news!

He farmed the silver-backed poisonous insects here just to lure the elite and black iron boss-level silver-backed poisonous insects back from the monster tide.

Now, the Silver-backed Poison Insect King has been alerted, but it will take half an hour to come back.

This half hour is equivalent to a waste. The silver-backed poisonous insect is a level five monster. When he reaches level six, the experience of farming the silver-backed poisonous insect will be much less.

That was his original plan.

You have to kill the Silver-backed Poisonous Insect King here before you can find the next monster.

There's nothing you can do about it. If you don't kill it in time, the Silver-backed Poisonous Insect King will return to the monster tide.

There are rubber monsters in the factory now, which saves him a lot of time looking for monsters!

Lu Cheng estimated the time in his mind, cleared away the poisonous insects around him, and walked towards the factory.

There are still more than twenty minutes left before the arrival of the Silver-backed Poison King.

During this period of time, he can swipe dozens or hundreds of rubber monsters without any problem!

Going around to the small door at the back of the factory, Lu Cheng blasted the door panel with a fireball.

"Bang!"

With the light of the fireball, Lu Cheng could clearly see the scene in the room.

Inside the room were large groups of humanoid monsters, at least two and a half meters tall, covered in black, and with unusually thick limbs and torsos.

He didn't rush in, so he made a fireball and threw it into the house.

"Bang!"

The fireball exploded and a monster fell to the ground.

[Ding, you killed the rubber monster (level 6) and gained +121 experience points. 】

After confirming with his eyes, it was the rubber monster.

"It's a pity. If you have high-level fire skills, you should be able to ignite it."

Lu Cheng said sincerely.

Rubber itself is flammable, and these rubber monsters are only level six, far from being able to escape their own special designation.

However, the Fireball Technique itself is of a low level and does not have the ability to ignite rubber monsters.

"Roar!!"

The companion fell to the ground, and the rubber monsters in the factory all paid attention. After discovering Lu Cheng, they roared.

However, they were crowded at the door.

The rubber monster is huge and has little intelligence, making it difficult to squeeze out of the small door.

For a while, rubber monsters were stuck at the door, one after another, unable to move forward or retreat.

"Isn't this comfortable?"

Lu Cheng was happy.

This method of blocking monsters can only be used in the early stages of Cataclysm.

In the later stage, if a stronger monster comes along, the factory will be demolished by you.

Facing a large group of rubber monsters stuck in the room.

Lu Cheng had some free time and stood there slowly rubbing fireballs, which was easier than brushing silver-backed poisonous insects.

Fireballs shot out one after another.

The proficiency of his skills continues to rise.

[Endless Drain] proficiency has exceeded 600 points, and the superimposed spell damage has exceeded 6,000.

The upgrade threshold of 1,000 proficiency levels is getting closer and closer.

There are also energy shield and fireball skills, each of which has been upgraded to one level after several hours of high-intensity monster spawning.

The energy shield reaches level 2, which adds 30 points of durability, which is better than nothing.

The fireball technique has been upgraded to level 3, and the proficiency level has been saved by nearly half. It is expected to be upgraded.

In addition to the special effect of [Deadly Caster] fireball level +1, the damage of level 4 fireball is only 55 points, which is pitiful.

However, Lu Cheng was quite interested.

Because every five levels of spell skills, there is an opportunity for enhancement.

You can increase damage, add certain special effects to skills, or reduce CD... You can choose the direction yourself, which is equivalent to a wave of small evolution.

"However, the fifth-level fireball technique should be quite rare..."

Lu Cheng laughed.

As a skill that comes with it right from the start, Fireball is justifiably weak.

Whether it is damage, range, mana consumption, or growth, the legal system ranks at the bottom.

so.

For mages, finding skills to replace fireballs is particularly critical.

Lu Cheng was like this in his previous life.

At level 3, he spent almost all his money in exchange for a [Ice Arrow] skill book.

At the same level, Ice Arrow's mana consumption and cooling are twice that of Fireball, but its damage is four times that of Fireball. It also has a chance to have a freezing effect.

The same goes for other mages. The first step to get out of the cage is to replace the fireball spell.

but……

For Lu Cheng now, there is no such thing.

Although the damage of Fireball is extremely low, its CD is short and it is quite comfortable to use to increase passive layers.

More than twenty minutes later.

Guessing that the Silver-backed Poison King was coming soon, Lu Cheng walked out of the factory.

The consumption of brushing the rubber monster is very small. A few minutes are enough for him to return to full state and face the BOSS.

really.

Within a few minutes, a giant poisonous insect came into view.

This poisonous insect is so fat that its body is bulging like a small oil tanker.

At first glance, it locked onto Lu Cheng.

Lu Cheng looked back, and the attributes of the Silver-backed Poisonous Insect King emerged.

…

【Silver-backed Poisonous Insect King】

[Level 5, Black Iron BOSS]

[HP: 87000/87000]

【Physical attack:? Magic attack:? 】

[Physical resistance:? Legal resistance:? 】

【Skill:? 】

[Special status: Being summoned by the monster tide! 】

…

The BOSS in the monster wave has full attributes, and the Silver-backed Poisonous Insect King has a full 87,000 HP.

But it doesn't matter to Lu Cheng. He is now passive at 6,000 levels and has little pressure on output.

"hiss……"

The silver-backed poisonous insect king hissed and rushed over.

From the perspective of conventional attack methods, this black iron BOSS is not much different from ordinary monsters. It mainly relies on body collision and mouthpart bites.

Lu Cheng took his time and rubbed the fireball with his hands.

"Bang."

-

3015.

A fireball was thrown, and Lu Cheng's eyes narrowed slightly.

When fighting ordinary mobs before, his fireball damage would go up to 5,000.

It hit the silver-backed poisonous insect king, but only half of it was hit.

This thing can reduce magic damage by 50%!

"It takes about thirty rounds..."

Calculating in his mind, Lu Cheng quickly moved around and circled around the surrounding buildings.

5 seconds later, the CD of the fireball improved, and he was just in the most suitable position.

The staff waved, and another fireball shot out.

"Bang."

-

3021.

After throwing the fireball, Lu Cheng continued to move the kite without stopping for a second.

After several back and forths, the silver-backed poisonous insect king's health bar dropped to 70%.

"hiss……"

The Silver-backed Poison Insect King hissed lowly, stopped chasing, and locked his head on Lu Cheng's movement trajectory.

Seeing this, Lu Cheng turned around.

In a situation like BOSS, you usually have to use a larger attack!

The previous stone beetle cave dwellers were only level 2 bosses, all with skills.

As one of the leaders of the monster wave, it is inevitable that the Silverback Poison King has skills. The only difference is whether he has one or two.

Lu Cheng faced the BOSS and moved slowly, looking for cover.

The silver-backed poisonous insect king's scream became deeper and deeper. After a few seconds, it opened its mouth suddenly and spit out a mouthful of venom!

"coming!"

Lu Cheng had already been ready to go. He hid behind the courtyard wall and controlled the energy shield in front of him.

"Tsk..."

Venom splashed on the bunker, making a tooth-piercing corrosive sound.

Most of the courtyard wall that was used as a shelter was dissolved by this venom, revealing the broken bricks and tiles.

Lu Cheng himself was unscathed. Only a few drops of venom splashed on the energy shield, knocking off more than 70 points of durability.

After carrying the ultimate move, Lu Cheng did not hesitate and fired the fireball.

"Bang!"

-

3162!

"Bang!"

-

3169!

After unleashing his ultimate move, the Silver-backed Poisonous Insect King was weak for a while and took three or four fireballs before he stood up.

This time, it resumed its regular attack methods and crashed into Lu Cheng again.

As a result, Lu Cheng easily dodged it and threw two more fireballs.

"It looks like...it will probably launch a venom attack every time the blood volume drops by 30%."

Lu Cheng was calm and continued to fly the kite while thinking about it in his mind.

The skill range of the Silver-backed Poisonous Insect King is not very large, so if you prepare in advance, it will not be difficult to dodge.

Under the fireball, the silver-backed poisonous insect king's blood volume dropped rapidly.

Sure enough, when the blood volume dropped to 40% and 10%, the Silverback Venomous Insect King released two ultimate moves again.

Lu Cheng perfectly avoided both times.

With previous experience, even the durability of the energy shield was not lost these two times.

After dodging his skills, Lu Cheng output like crazy.

Seeing that the silver-backed poisonous insect king only has a bloody skin left, it can be killed with a fireball.

Lu Cheng stopped.

"The energy shield's CD still has 10 seconds..."

After waiting for 10 seconds, he summoned a second energy shield, stacked the two shields together, and then Lu Cheng created a fireball.

The previous elite silver-backed poisonous insect would self-destruct. Facing the black iron BOSS, he chose to defend against it.

Throwing the fireball, Lu Cheng immediately retreated.

"Bang!"

-

3202.

The silver-backed poisonous insect king's health bar was emptied, and he fell to the ground with a bang. His body expanded rapidly and expanded and contracted violently.

Ten seconds later.

"Bang——"

There was a loud noise and slurry splashed!

Lu Cheng had already found a bunker and hid under it, with two energy shields in front of him.

"Tsk..."

The corrosion sound lasted for dozens of seconds before the system sound started to sound.

[Ding, you killed the Black Iron-level BOSS Silver-backed Poisonous Insect King and gained +2866 experience points! 】

Then, there was a series of system prompts!
