"Damn, I really met a rich woman!"

In the Underworld Territory, Li Yuan saw Qin Yan's reply and sat up directly.

If you want to say that fifty first-order death crystals are directly cheaper than twenty, I will scold you for being sick or not.

But if you're going to pay with a second-order death crystal, that's a different story.

At this stage, the ratio of second-order death spars to first-order spars is definitely more than 1:10, and basically no one is willing to trade them.

And the zombie tooth Li Yuan is readily available, and it is used to exchange it for second-order spars, which is equivalent to a profitable transaction.

Without hesitation, Li Yuan replied to her directly.

[Li Yuan: When to trade? 】

[Qin Yan: I don't have many spars in my hand now, I can only buy two, and the rest will be paid at night at the latest]

[Li Yuan: Yes]

[Ding, your zombie tooth has been purchased by Qin Yan, and you have obtained three second-order death crystals]

[Your Zombie Fang has been purchased by Qin Yan, and you have obtained three second-order death crystals]

With two consecutive system prompts, Li Yuan harvested six second-order death crystals.

The rest of the zombie fangs, he took them off the shelves and put them in the warehouse, and when Qin Yan gathered the spars, the two sides would trade.

Li Yuan looked at the second-order death spar in his hand and exhaled a breath, he was finally able to upgrade the pool of the underworld.

He couldn't wait.

[Whether to consume 100 first-order death crystals, 10 second-order death crystals to upgrade the pool of the underworld, yes/no]

"Yes."

Li Yuan chose yes with anticipation.

He wanted to see what kind of changes would happen to the upgraded pool of the underworld.

[Ding, congratulations, the pool of the underworld has been successfully upgraded and the devouring skill has been obtained]

[Ding, congratulations, the pool of the underworld has been successfully upgraded, the upper limit of the power of the Hades has increased, and the current power of the Hades is 20,000]

A ray of light fell from the sky, enveloping the pool of the underworld, and the blood-red walls of the ancient vicissitudes of life, under the shroud of light, emitted a dazzling red light.

The clear water of the pond is bubbling up.

Soon, the light dissipated, and the pool of the underworld, which was one meter wide, was raised to about two meters wide.

The patterns on the walls of the pool are also deeper.

Li Yuan hurriedly looked at the attributes of the Underworld Pool.

【Pool of the Underworld: Unique Class Building】

[Level: Level 1]

[Can breed four first-order small skeletons and two first-order ghouls every day]

[The next level can breed a corpse monk]

[Devour: The pool of the underworld can devour corpses and transform them into the power of the underworld]

[Upgrade Requirements: 1000 First-Order Death Crystals, 100 Second-Order Death Crystals, 10 Third-Order Crystals]

"The number of small skeletons that can be recruited every day has increased, and there is one more type of troops recruited, and I no longer have to worry about running out of the power of the king and not being able to recover."

Seeing the upgraded attributes of the Pool of the Underworld, Li Yuan's face was overjoyed.

He was very satisfied with this attribute.

It's not in vain that he took so long to gather resources.

It's just that when he saw the request for the next level upgrade in the pool of the underworld, Li Yuan had a headache again.

1,000 first-order death crystals are easy to say, but it just consumes some time, and 100 second-order death crystals and 10 third-order death crystals are a little difficult.

Now if you look carefully in the market, some sellers who exchange precious materials can still see the second-order death spar traded, although the conditions are a bit harsh, and there are many things that Li Yuan has never heard of.

But the third-order death spar... I searched the entire trading market, and no one wanted to take it out.

"Forget it, that's not something I should think about right now, let's see what the new classes look like."

Li Yuan shook his head and set his eyes on the pool of the underworld.

[The pool of the underworld is full of energy, whether it gives birth to today's dead spirits]

"Yes!"

Li Yuan stared at the pool of the underworld tightly, without blinking an eye.

Grunt.

With his mind confirmed, the pool of the underworld bubbled and began to give birth to today's dead spirits.

Soon, four skeletons about the size of Makabaka crawled out of it.

"Huh, what's going on?"

"The new skeleton isn't a small skeleton, it's a big skeleton like Macabaka?"

Li Yuan looked at the attributes of these skeletons.

【Name:Big Skull】

【Attribute: Death】

[Quality: 0 Star Class]

[Strength: 1st Order]

【Skill: None】

[Loyalty: 100]

"Hey, after the upgrade of the pool of the underworld, the strength of the breeding class will also increase?"

Li Yuan gasped when he saw the attributes of the skeleton, and couldn't help but feel agitated, and he had a new understanding of the strength of the pool of the underworld.

"Isn't this against the sky?"

"As long as I can raise the level of the Pool of the Underworld, in the later stage, who else will be my opponent!"

Li Yuan's heart was hot, and he only felt that this pool of the underworld was worthy of being the only class building.

At this moment, the water of the pool of the underworld tumbled again.

After giving birth to four large skeletons, a gray and pale skeleton slowly crawled out of the pool of the underworld.

The skeleton is somewhat similar to a skeleton, but its body is extremely rickety, with its waist almost bent to the ground, and its body is supported by two claws and the soles of its feet, and it is about the size of a large skeleton.

[Name: Ghoul]

【Attribute: Death】

[Quality: 1 Star Class]

[Strength: 1st Order (+1)]

[Skill: Corpse Eater: Eating a corpse can continue to restore your own injuries]

"Is this the necromancer bred by the first-level Hades Pool, the initial strength has reached the first order, the quality has also been improved to one star, and there is an active skill."

Li Yuan is very satisfied with the ghoul, except for his ugly appearance, which is not comparable to Macabaka, he is simply crushed by Macabaka in other aspects.

"Go kill that zombie."

Li Yuan pointed to an ordinary zombie outside the protective shield and gave an order to the ghoul.

Suddenly, Li Yuan seemed to think of something, and ordered again: "Go and kill the other one." ”

The territory has a realm blessing for the troops, and since you want to test the strength of the ghouls, you must definitely test the most real combat power.

Li Yuan re-selected an ordinary zombie for the ghoul five hundred meters away from the territory.

More than 500 meters without the blessing of the aura, the rest depends on whether the ghoul can solve the ordinary zombie.

According to the strength of Macabaka, they were directly crushed by ordinary zombies at the half-step first order, and after breaking through to the first order, the situation was a little better, and about two lives could be exchanged for one.

Ghouls are stronger than first-order macabaka in all aspects, but I don't know how much stronger.

Soon, the ghoul and the normal zombie fought.

Li Yuan watched the battle attentively.

As he expected, the strength of a first-order ghoul was about the same as that of an ordinary zombie.

But ghouls attack faster than zombies.

Each claw can grab a large piece of flesh.

Fortunately, zombies don't have pain, and as long as they don't get attacked to their weak points, they can fight back all the time.

Bang bang bang.

Click.

It was a close and protracted battle, and the two sides fought for a full ten minutes before they could barely decide the winner.

The ghoul relied on the skeleton to be slightly harder than the zombie, and killed the zombie with difficulty, and it itself was seriously injured and could not stand steadily.

And the ghoul, after seeing the zombie fall to the ground, immediately stretched out two paws and began to devour the zombie's corpse.

The originally broken skeleton on its body, after the pieces of flesh and blood were in the stomach, healed rapidly at a speed visible to the naked eye, and all the bones instantly recovered as they were in the original state in just a few breaths, and Li Yuan was dumbfounded when he saw it.
