The Spider King recovered full blood, Lin Zhuo was not discouraged, after all, this was his first time killing the BOSS, inexperienced, and it was normal to encounter setbacks, but this setback will bring more caution and thinking to his future path.

In silence, Lin Zhuo counted the number of skeletons, so far, more than twenty skeleton soldiers have died, which has some impact on the entire skeleton army, but it can still be bearable.

At this moment, regrouping the skeleton army, Lin Zhuo waved his staff and continued to attack.

However, the targets of this attack were all those small spiders on the ground, and it took nearly a few minutes to kill them all.

The skeleton army then refocused on Spider King, launching a fierce attack.

As before, countless arrows and green fireballs smashed into the Spider King, causing a lot of damage, and as time passed, the Spider King's health continued to decrease.

During this period, the Spider King released the venom skill many times, and those poisoned skeleton creeps, once the blood volume bottomed out, Lin Zhuo immediately recalled them, and then replaced them with skeleton creeps full of blood, keeping the blood volume of the skeleton creeps in the front row healthy, so that not only did none of the skeleton creeps die, but the Spider King could not recover his health.

Until more than half an hour passed, seeing that the Spider King's blood volume was getting lower and lower, Lin Zhuo's expression was serious, and the whole person became cautious.

Finally, when the Spider King only had 8,000 HP left, its whole body glowed green, and its abdomen squirmed again, as before, to release the reproduction skill.

The lesson from the past made Lin Zhuo extremely cautious now, he observed carefully, and at the moment when the Spider King's abdomen swelled, lay on the ground, and gave birth to a row of ovulation bags, he immediately waved his staff, allowing the skeleton army to attack the egg bags.

At the same time, as soon as those egg sacks appeared, before they could break, they were overwhelmed by countless arrows and green fireballs, and finally turned into pools of green liquid, flowing on the ground.

Seeing that the egg bag was broken and the little spider did not come out, Lin Zhuo's eyes flickered, and he continued to command the skeleton army to launch an attack on the Spider King.

This time, there was no interference from the little spider, and in the following time, everything went extremely smoothly, just when the spider king's blood volume bottomed out and he was about to die, but suddenly, an accident happened.

"Huh?" Lin Zhuo frowned slightly, looked intently, and saw the Spider King in the distance, with a blood value of 2,000 points, but the attack of the skeleton army fell on it, but the word 'immunity' floated.

"Immunity"

"Immunity"

"Immunity"

"Immunity"

......

No matter what attack falls on Spider King's body, it is an immunity effect.

Including the Spider King, it also stopped attacking, its body froze in place, and it raised its head and screamed.

Lin Zhuo had an ominous premonition in his heart, including the Wen Tianba and the Spirit Monkey next to him, who were also shocked at the moment, not knowing what was going on.

"Isn't it...... Has Spider King mutated? Ask Tianba hesitated for a moment and spoke.

Hearing this, Lin Zhuo was stunned for a moment, and turned his head to look at Wen Tianba.

"Isn't the mutation of the boss just to improve combat effectiveness?" The spirit monkey on the side hurriedly said.

"That's right, before the game was launched, I learned about the features of the game through some secret channels." Wen Tianba's expression showed a solemn expression, and he slowly spoke, as a studio, before entering the game, he would first learn about the information of the game, so as to dig out a way to make money in time.

"When the HP of a boss above the gold level is less than 20%, or less than 10%, the mutation effect will occur."

"The so-called mutation is actually the resistance of the boss before he dies, in addition to enhancing his own strength, including the skills of the boss, it will also be greatly enhanced."

"And in the process of mutation, no matter what damage the boss receives, it is all immune effect." After asking Tianba, he glanced at Lin Zhuo deeply.

Hearing this, Lin Zhuo frowned, turned his head to look at the Spider King in the distance, and saw that the Spider King hissed, his whole body burst with green light, and his huge body trembled faintly, as if he had a sense of expansion.

Once the mutation effect occurs, the boss will enter an invincible state, immune to all attacks, and cannot be interrupted.

"With the mutation effect, how much strength does the boss increase?" Lin Zhuo asked, he felt that what Tianba said was the truth, and there was no need to lie to him.

"Each level is different, the golden boss generally increases its own strength by 20%, and the more advanced the boss, the increased strength will be higher!"

"It is said that those epic, legendary-level bosses will increase their strength by 200%, or even higher, but whether it is true or not, I don't know, but one thing I am sure of is that those high-level bosses, they can speak human words!" Ask Tianba to say seriously.

Hearing this, Lin Zhuo groaned, and at this moment, the Spider King in the distance suddenly let out a piercing scream, and its huge body swelled impressively, and in the blink of an eye, it turned into a crimson Spider King.

Lin Zhuo's pupils contracted, and the Spider King at this moment had completely changed, his body was twice as large as before, his whole body was red, exuding a violent aura, especially the front end of the back armor, two rows of dense eyes, flashing green, looking very mad.

Due to the increase in the size of the Spider King, even the Heavenly Tyrant and the Spirit Monkey, who were standing in the skeleton army, could see the mutant Spider King when they looked up at this moment.

"Holy!" The Spirit Monkey raised his head and suddenly saw the huge body of the Spider King, and his body subconsciously took a step back, his face full of horror.

"It's really a mutation!" Wen Tianba was also horrified, the Spider King at this moment was at least five or six meters tall in his eyes, which was simply too scary, and at the same time, he was also very glad that he did not cooperate with other studios, otherwise no matter how many people came, I am afraid that he would not be able to kill this boss.

Lin Zhuo frowned, and used an insight technique against the mutated Spider King.

......

After reading the attributes of the Spider King, Lin Zhuo was calm, and he couldn't help but gasp at this moment, although the blood volume has not changed, the attack has increased to 1000 points, and he is already about to catch up with the Wild Bear King, especially the skills, all of which are mutation effects, and they are outrageously strong.

At the same time, after the Spider King's mutation was completed, it turned around, and two rows of dense eyes, glowing green, looked coldly at the army of skeletons.
