Advanced energy can level up mercenaries and improve their quality! In this way, even those ordinary mercenaries of the first order have a chance to be promoted to the hero level!

It's a gem!

Levi was excited.

However, he soon thought of an important question, the mercenary could enter through the portal, but how to get back?

They cannot return to the city like the player.

Bring it in, but you can't go out......

Levi scratched his arm, would he have to wait until the time when technology developed to the point where he could set up portals?

At the very least, it will be too late to upgrade to town.

While thinking, Levi avoided one plant after another and came to the junction with the next area.

A pale white diaphragm was split between the two, and Levi tried to pass through, but was prompted.

"The current area soul altar has not been activated!"

Levi turned his head, and there was an altar not far from him.

The altar is made of the same material as the Soul Stele, a rectangular platform about a meter high, with a fist-sized depression in the center, and I don't know what needs to be placed to activate it.

"Do you know what this is for?"

Levi asked Latina.

"Teleportation Altar, you can put a magic crystal and try it."

Latina said casually.

"Magic Crystal......

Levi remembered that there was exactly one piece in his bag.

He took it out and placed it in the recess on the altar, it felt a little smaller, but it still worked.

I saw that the altar suddenly flickered, and light blue lines appeared, centering on the depression and began to spread, forming a dense magic array in an instant, covering the entire altar.

"Click!"

There was a soft thud.

The place where the magic crystal was placed suddenly sank, and then a hexagonal stone pillar slowly rose up.

In the center of the pillar is a red button.

"Huh, so high-tech?"

Levi looked amazed.

Latina saw that he didn't know it, and sneered: "This is also technology? It's a far cry from our Hell, we've already built a teleporter that we can carry! ”

"Carry?!"

Levi's expression was stunned, his impression of the portal was still stuck on the bulky gate.

But if it is really what Latina said, he really underestimated the technological development of this world, although they have no electricity, but they have also used magic energy to the extreme!

"See, no." Latina took out her Demon King's Sword as if showing off, and said proudly: "This king's Demon King Armament is the world's most cutting-edge technological creation!" ”

Levi took it.

【Sword of the Demon King】

【Special】

[Level: 1st Order]

[Damage: 20-20]

[Note: It can become stronger with the increase of Latina's level, and cannot be damaged or dropped]

[Requirements: Latina]

……

At first glance, the appearance of the Demon King's Sword looks like an ordinary black long sword, but the material is a little strange, as if it can absorb light, and after looking at it for a long time, it will produce the illusion of being swallowed.

But with a snap of Latina's fingers.

The outer shell of the Demon King's Sword suddenly became transparent.

Levi saw at a glance that the inside of the sword body was actually a delicate and small part, which were intertwined with each other, running all the time, forming a set of sophisticated and complex machines!

At the heart of the sword was a golden crystal wrapped in a wall of aqua blue crystals.

The crystal emitted manic energy visible to the naked eye, and then it was transformed into gentle energy threads by the crystal wall, densely transmitted out, covering the entire sword body.

"Smack."

Latina snapped her fingers.

I saw that the parts and gears in the sword body suddenly operated at an extremely high speed, and the sword of the demon king began to change shape in Levi's hand, turning into a ball for a while, and a leather whip for a while.

Levi was dumbfounded.

She smirked, revealing two small tiger teeth.

"How? Awesome! ”

"How is this done?"

Levi asked in surprise.

"Humph! I won't tell you. ”

Lattina shook her head, and it was very stinky.

Levi returned the sword, feeling a little itchy in his heart, he was truly fascinated by the magic of Latina's weapon.

But if you want to beg her in a low voice, it is impossible, this guy will shine if he gives a little sunshine, and he will go to heaven if he praises two words, he must not get used to it, and he must maintain the image of a majestic master.

Levi didn't say a word and turned his head away.

Little Lori secretly looked at his expression with her spare eyes.

I sighed unpleasantly.

Love to ask without asking.

Levi reached for the button on the pillar.

"Buzz."

The altar trembled slightly, and a light suddenly shot out from the stone pillar, condensing a white light gate in front of it.

Levi looked over.

Behind the door is the territory of the greedy wolf in the night.

Judging from the location, the location where the portal opens should be the gate summoned by the soul stone.

I see.

Levi's expression was delighted.

He was thinking about how to get the mercenaries to enter and exit the Sealed Land on their own to upgrade, and with this altar, it was all done.

It seems that the person who built the Soul Stone also discovered the magic of Naga's soul and turned it into a training ground.

I just don't know why the stele was buried in the ground.

Levi thought to himself, looking at it this way, among the five small islands, including the main island, there should be one such stone monument!

If only they could all be captured......

It's unrealistic to think about.

Levi suddenly noticed a pale blue number on the stone pillar.

“99%。”

As far as he could see, the number suddenly became:

“98%。”

Could it be the loss of energy from the magic crystal?

Levi quickly pressed the button again and closed the portal.

And sure enough, the numbers disappeared.

Levi silently calculated.

It took less than ten seconds to open the portal just now, and the magic crystal lost 2% of its energy, which means that a third-order magic crystal could only last for about eight minutes.

But the portal doesn't need to be open all the time.

As long as you can teleport people in, it is enough to teleport out, and in this way, it seems that it can last for a few days......

It's just a few days.

If you want to activate this proving ground.

That magic crystal mine must be mined in a hurry.

Levi thought as he walked towards another area again, this time without hindrance.

He selected a plant and fired an elemental arrow, and a Naga revenant was immediately lured out.

Naga (Revenant): Level 15, HP 310.

Levi did not continue to attack, but retreated.

Retreat to the original area.

The Naga ghost chased after him, but when it hit the wall of light between the two areas, it instantly dissipated into black smoke.

The black smoke drifted back into the plant, turning back into a ball of light again.

Levi nodded, probably understanding the rules here.

Because there was no magic crystal, the second altar could not be activated, so he didn't waste any more time and left the sealed place directly.
