When Zhao Li finally opened the swamp monster's braincase with great effort, he found that this guy's brain was really large, and the volume was almost the size of an entire adult.

But fortunately, Zhao Li didn't have any appetite in the face of this huge brain, which means that this brain is not its mutation inducer.

As a last resort, Zhao Li drilled into the body of the swamp monster again, dissected it, and finally found its mutation inducer this time, and by the way, he also found his two big silver hammers - he was covered with mucus and blood again, but there was nothing he could do, but fortunately, after the monster died, the corrosive effect of the mucus in his body was much weaker, except for nausea, it had no other effect on Zhao Li.

The swamp troll's mutation inducer is a palm-sized piece of flesh that grows inside the gills - let's call it a gill, the swamp troll is generally like a manta ray and a whale combination, but the mouthparts are similar to that of an octopus...

Now this huge monster ten meters away has been almost dismembered by Zhao Li, all kinds of huge internal organs and intestines have been thrown to the ground, and the strong smell of blood has spread far away.

“%￥&&*@···”

At this time, it was the last step of waste utilization, and I saw Zhao Li chanting the spell "Natural Disaster Coming" to the corpse of this swamp monster.

To transform such a huge monster, the mana value to be consumed is much higher, and it takes more than 400 mana values to produce a large amount of black fog, which envelops the entire monster and transforms it.

The strength of this swamp monster is much stronger than that of werewolves, pirated Buffett demons, etc., and fortunately, Zhao Li is a muscular warrior who takes the strength and defense route, if he takes the agile and dexterous path, I am afraid that he will die if he is swallowed up.

As the ultimate spell of the undead summoning system in this world, "Disaster Descends" will transform and strengthen the summoned object - but how to transform it and what it will be transformed into is determined by the caster's wishes and the current situation of the corpse.

For example, the appearance of the three remaining undead minions has not changed much compared to the previous life, and each of them has much better muscle strength and agility than before they were alive - but it will not last, and these muscles will rot in a short time.

And this swamp giant demon, because it was seriously damaged by Zhao Li, was shrouded in black fog for a little longer.

When the black fog dissipated, revealing a new swamp monster that had become a servant of the undead, Zhao Li couldn't help but think of an advertisement he had seen before he crossed over...

"My husband made a mistake in his operation and trained the bone kun, and his combat power was +1000000000, scared and crying!"

After the transformation of "Scourge Descending", the image of the undead servant swamp monster is completely different from the one before his death.

First of all, the mud on the swamp troll's body is gone - in fact, even most of the muscles are gone, and now most of the bones of the entire swamp troll are directly exposed.

And even in the parts covered with flesh, there was not much flesh left, only a layer of tough black thick skin hung on the bones, and the skull that was pried open by Zhao Li and the brain that was originally exposed to the air were directly gone.

All the invisible meat and tissues are catalyzed by black magic and transformed into energy for repair and transformation.

All in all, the current swamp monster looks much more majestic and domineering than before, with large horizontal wings ten meters away, half of which are bare white bones, half of which are covered with black skin, and the entire head skeleton is exposed.

Directly above the mouthparts, there were two rows of six bone holes, and a total of six eyes were burning with a cold blue soul fire - in fact, Zhao Li only knew at this time that this swamp giant demon originally had six eyes.

Zhao Li carried two large silver hammers and jumped onto the head of the swamp monster in a hurry—the brain was just bare, like a seat carved out of white bone.

"Yes, I'll call you Gu Kun in the future!

Under Zhao Li's command, the remaining three undead servants Bolton, Tori and Wright, also carried things and climbed onto the "back of the bone kun".

Then, the undead swamp troll, named "Bone Kun" by Zhao Li, sped up on the muddy swamp with one man and three corpses - although the swamp troll usually moved in the mud, it was mainly for better hunting, and it was not that it would not walk on the land shore.

The Bone Swamp Monster is also ten meters long, and when it advances on land, its body is S-shaped, its upper body stands upright, its lower body twists and moves forward like a snake, and a pair of large horizontal wings cross the air, inciting acceleration - don't ask why half of its horizontal wings are bones and can still fan the wind, this is a world full of magic and monsters.

"Haha, I really want to get it, it's different to have a mount. ”

Zhao Li sat in the middle of the skull of the "Gu Kun", gnawing on the "mutation inducer" while blowing the wind with great satisfaction.

With this mount, which was born and grown in the depths of the swamp, Zhao Li no longer had to step on the mud, and he didn't need to worry about sinking if he stepped into a deep pit.

No matter how deep the quagmire is, it does not exist in front of the swamp troll, and then again, in addition to not being able to fly, this swamp troll can be regarded as a good mount for amphibious, and its speed on the ground is not slower than that of ordinary horses.

With this Bone Kun mount, Zhao Li was not in a hurry to rush to the swamp witch - it had to be a whole day's walk, but according to the swamp monster's forward speed, I am afraid it would not take long to arrive.

And what surprised Zhao Li even more was that just now, after he ate the "mutation inducer" that was not very fresh, he gained more than 200 free attribute points.

That's right, a swamp monster can provide so many free attribute points, and its strength is completely worthy of this number - just like the saying that native chickens are more nutritious than captive chickens, in this world, earth monsters are better than man-made monsters!

"I'm strong enough, although I definitely haven't reached the realm of invincibility in the world, but I should have no problem being a father in this little swamp..."

Zhao Li decided to continue to escalate and be prepared, as for the swamp witch... As long as you arrive before the black moon, besides, satisfying your curiosity is not important to upgrade.

"By the way, since swamp witches like to keep man-eating crocodiles and human-faced demon birds in captivity, I might as well bring some more helpers to scare them..."

Zhao Li made a decision, these are all things that can be stopped on the way to upgrade.

In the midst of his thoughts, the Undead Swamp Troll also changed direction slightly, and sped away to the other side—according to Bolton's memory, there was also a group of monsters in that direction...
