”Ruthless collision, come on!”

Following Luo Xiu’s roar.

The undead cavalry suddenly rushed out from the right side of the bull-headed giant’s head and directly hit one of its eyes.

”Moo!”

The bull-headed giant didn’t expect Luo Xiu to make such a ruthless move. Caught off guard, his right eyeball was directly smashed by the undead cavalry.

Black blood flowed all over the ground instantly.

The undead cavalry also took the opportunity to float elsewhere.

As a soul-type summoned beast, the advantage of the undead cavalry is that it can float in the air, and under normal circumstances, it will not be attacked by living creatures.

Creatures that have a body have a chance to hit it only when it attacks.

This is also the reason why those human survivors can use soul-type summoned beasts to lure away some lord-level dark creatures without suffering any losses.

The undead cavalry just now completely angered the Minotaur Giant.

Its anger was transferred to the undead cavalry.

Luo Xiu hurriedly let the undead cavalry move in the opposite direction of the fine iron city wall.

Its speed is not slow to begin with, and now the Minotaur Giant is now infected with the paralyzing toxin of the Jackal Archer.

It happened that the bull-headed giant couldn’t catch up with the undead cavalry.

It would be easy to handle next. Luo Xiu continued to command the undead cavalry to lead the bull-headed giant in circles.

By the time the bull-headed giant reacted and wanted to go to Luo Xiu to fight for his life, it was already scarred.

After nearly 5 minutes of attacking and baptizing by the Shadowblade Hunter, it finally let out an unwilling wail.

Completely fell down.

”It’s finally over, it’s almost over.”

Luo Xiu sat slumped on the ground, panting heavily.

The situation just now was indeed too dangerous.

If the Minotaur is close to the Iron City Wall, destroy it and then kill it into its own camp.

Then Luo Xiu could only abandon the camp and leave, and most of the summoned beasts and defensive towers would probably be lost here as well.

The most important thing is that it is too difficult to make a comeback after losing the life fire.

The most difficult wave of lord attacks ended, and the Kuroshio began to weaken.

As the body of the bull-headed giant disappeared, two purple lights, several blue lights and countless other green and white lights kept flashing on the ground.

”Purple quality baby!”

Luo Xiu’s eyes lit up, and he quickly asked the undead cavalry to pick up all the things that had just exploded.

”I posted it this time, it’s really posted!”

Luo Xiu felt extremely excited.

Purple-quality treasures, whether they are designs or other items, are absolutely good treasures!

Blue Shadowblade Hunter Blueprint: 1
Green Eyes Archer Blueprints: 5
Green wood chipper design drawing: 3
Design drawing of green mining machine: 2

”It turned out to be the design of the purple Guardian of Light!”

Luo Xiu held the design blueprint that shone with purple light, and his excitement was beyond words.

The Guardian of Light, as the name suggests, is a guardian summoned beast.

After this kind of summoned beast is summoned, it can be attached to a unit.

When this unit encounters a dangerous sneak attack, it will appear to protect it.

Now what Luo Xiu got was the purple-quality light guard, and he had its protection.

Basically, it can be said that there are no worries and you can explore some special areas with confidence.

And now that the competition for supreme honor has started, with Luo Xiu’s current points and ranking, there are still so many resources.

If he is targeted by some race that is good at stealth and sneak attacks, it will be quite difficult for him to defend against him.

“紫色光之守卫，合成需要：任意核心（蓝）0/3【或任意核心（紫）0/1】，灵木0/15，铁片0/30，魔物之髓0/16。”

The synthesized materials are enough, but the only option is to consume the purple summoned beast core that just exploded.

After contemplating for a while, Luo Xiu made up his mind and synthesized the Guardian of Light.

”Although the purple core is rare, it doesn’t mean that I won’t encounter it in the future. After the Kuroshio tide is over, I will go out to explore. With the protection of the light guard, there is still a huge guarantee for safety.”

This is Luo Xiu’s idea.

After all, the dark place is dangerous everywhere, so it is better to be cautious.

The Guardian of Light is a humanoid creature exuding platinum light, holding a shield in one hand and a sword in the other.

However, Luo Xiu found that it seemed to have no face, and there was a pair of things like eyes growing on the top of its head.

If it was placed in Luo Xiu’s original world, it would probably be regarded as a monster.

But in this world now, Luo Xiu has seen many of those dark creatures, so he has no sense of their strange appearance.

Check out its properties:
【Guardian of Light】

[Quality: Purple (equivalent to a fourth-order strange creature)]

[HP: 3000/3000]

[Attack Power: 90]

[Defense Power: 150]

【Action Power: 30】

[Skill 3—Flame Slash: Swing the sword of light in your hand to condense the power of light. The next attack can cause 500% attack damage! 】

[Skill 4—Gift of Light: Every time there is a light attribute unit in the friendly team, the total attributes of the Guardian of Light can be increased by 5% (there is no upper limit for this skill)]

”This attribute, this skill, is indeed a purple quality summoned beast, and this fourth skill can be infinitely superimposed!”

After reading it, Luo Xiu was extremely surprised.
