"Master!"

"Master!"

"Master!"

……

At the call of a thousand shadows, Green regained consciousness.

Green looked around blankly, and finally remembered what had happened before: "It's okay, I'm awake." ”

"Yes, master." Seeing that Green was fine, Chikage finally breathed a sigh of relief.

After calming down Chikage, Green hurriedly began to check his attributes.

After the upgrade, the upper limit of Chaos Mana storage has been changed from 10,000 to 100,000, but the character attributes have not changed, only a new ability has been added:

————

Demon King's Heart: The Demon King's heart, the source of the Demon King's power. As long as the heart remains, the Demon King will not die; If the body is destroyed, it can be resurrected from the heart; If the heart is destroyed, it will be weak for a long time before the heart grows back.

————

Looking at the palm-sized black crystal in his hand, Green couldn't help but touch his chest: "My heart? ”

After leveling up, there is no change in attributes, the only change is that his heart runs from the inside of his body to the outside of his body, becoming something similar to a lich life box.

Although the resurrection traits are similar to the Lich's lifebox, the actual function is much stronger than that of the Lich. Even if the Demon King's heart is blown up, it can be rescued again, and once the Lich is destroyed, he will immediately rush to the street!

In addition, Green's consciousness can also be transferred between the "heart" and the "body", and can even be used for two purposes. The only problem is that the "Demon King's Heart" has no hands and feet and cannot move, so when controlling the "Demon King's Heart", there is only one thing Green can do: invoke the Chaos Magic to interfere with the surrounding environment...... Oh, and by the way, it seems that you can communicate with other creatures around you.

"Huh? Can you communicate? Green looked at the crystal in his hand, and his eyes lit up, "Since you can communicate, then it doesn't matter if you don't have hands and feet!" I can let someone else or a machine replace my own hands and feet. ”

Green's gaze couldn't help but look at Thousand Shadows, and then at Mona, who had just walked into the warehouse.

"Mona?" Mona looked at Green blankly.

……

Time flies.

In the blink of an eye, months passed.

Miracle Canyon, deep underground.

In the dark underworld, the tunnels are like a labyrinth, and no one knows where the tunnel in front of them will lead.

"Boom! ~”

Suddenly, there was a sound of collapse in the tunnel, as if something had collapsed in the tunnel.

"Mona Mona~" A group of creatures that looked a bit like rabbits carried a mine pickaxe and ran wildly through the tunnel with two legs, running in the direction where the sound came from.

After a few turns, a collapsed burrow appeared in front of the rabbits.

A rabbit was sitting on the ground, nervously pointing to the collapsed place in front of him: "Mona Mona~"

"Mona Mona~"

After the rabbits exchanged words in the language of "Mona Mona~", they took the pickaxes and dug "clanging".

Soon, the rabbits dug up the collapsed rubble and dug out the two rabbits that had been buried in the ground.

The buried rabbit appeared to be wounded, and a wisp of black mist was leaking out of the wound.

A black-covered Mona stepped forward, raised her hands, and approached the injured Mona. A cloud of black mud-like magic appeared in Black Mona's hand, and when the black mud touched the "leaking" wound on Mona's body, it directly blocked the wound like a plasticine.

Soon, the two injured rabbits were healed, and all the wounds were gone, as if they were not there.

"Mona! ~" The two wounded rabbits stood up intact and gave a raised hand salute to Black Mona.

"You continue to mine, and strive to dig up the metal vein as soon as possible." Black Mona's mouth is not "Mona", but human language.

"Mona! ~"The two Mona gave a raise of their hands to Black Mona.

Instructed to the three Monas to continue mining, Black Mona left with the rest of Mona, while the three Monas who remained picked up their stone pickaxes and began to continue digging.

Due to the lack of metal, with the exception of some of the Guards, most of Mona's digging tools have been turned into stone pickaxes, which makes the cavern excavation much less efficient. But thanks to Mona's efforts, the tunnel continued to advance at a slow but determined pace.

Thanks to Mona's efforts, the underground of Miracle Canyon is now full of labyrinthine tunnels.

Black Mona walked as she looked around through her ruby eyes.

Mona's eyes are very special. When you close your eyes and look at the world with your squinting eyes, you see a colorful ordinary world. But if you open your eyes and look at the world with the eyes of a rabbit like rubies, the world becomes a different one—a world made entirely of magic of all colors and concentrations.

With "Magical Vision", the field of vision is very limited, but it is able to ignore dark environments, which is one of the reasons why Mona are able to mine in the dark without any light.

"But this kind of 'light pollution'-like vision is really uncomfortable to watch for a long time~" Hei Mona couldn't help but complain.

"Mona?" The Monas who followed behind Black Mona were full of confusion.

"Nothing." Black Mona waved her hand.

This Black Mona is actually Grimm, or Grimm's doppelganger!

Since leveling up and obtaining the Demon King's Heart, Green has transplanted his heart into the body of a Mona, turning it into his own clone container. In this way, which is similar to "parasitism", Green allows himself to obtain a doppelganger.

Doppelgangers are very useful, especially when exploring the underworld.

Using Mona's body, Green can walk through the tunnels dug by Mona, and some underground crevices can also be passed through casually, and can also search for monster nests in the underground world and transform them into energy nodes, thereby increasing Mona's range of movement.

However, although the range has increased, Green has still not been able to find the vein.

Black Mona Green walked around the underground, updated his system map, and then returned to a stronghold in the underworld.

Mona Farmland: Mushroom Grove No. 3.

In the spacious natural cave is a large group of mushroom stones, which are more than a meter high and support the dome, like a forest!

Green led his men into the mushroom forest.

There are many mushrooms in the Mushroom Forest, and the ones that support the dome are the most common mushrooms found in the Underworld: the Underground Mushroom.

The Underground Mushroom is a type of mushroom that grows in the Underworld and has incredible fecundity. With the right temperature and water source, it only takes two days for an underground mushroom to grow from a spores to a mushroom more than 10 centimeters tall, and then start spreading spores. Once the spores begin to spread, the underground mushroom is considered ripe, and then its growth rate slows down, slowly growing like a sapling in the surface world, and eventually grows into a towering tree that supports the dome!

The fluffy flesh of the newly sprouted underground mushrooms is food for many creatures in the Underworld, but as they mature, they get harder and harder, and those old underground mushrooms even turn to stone! For example, the mushroom rocks that support the top of the cave are some old and dead underground mushrooms.

Underground mushrooms are common in the Underworld due to their ability to serve as food and to support caverns from collapsing, either wild or planted by the inhabitants of the Underworld.

It's a pity that for Grimm and Mona, underground mushrooms are not magical plants, and what Grimm needs is rich in that magical plant!

After passing through the underground mushroom swarm on the periphery, Green walked into the depths of the mushroom forest.

In the depths of the mushroom forest, a black vortex is radiating energy around it. Beneath the vortex, some mushrooms with a black sheen are thriving - the Chaos Mushroom, a poisonous mushroom produced by the negative energy emitted by the energy nodes, rich in magical powers, is one of the main foods of the Mona when they go on expeditions.

Seeing Green appear, Mona, who was in charge of taking care of these mushrooms, quickly stood up, raised her arms, and saluted Green: "Mona! ~”

"How are the Chaos Mushrooms growing?"

Mona who takes care of the mushrooms: "Mona Mona Mona~"

"Hmm. Very good! When the mushrooms are ripe, we can organize teams and explore a little deeper. ”

"Mona! ~" Mona raised her hand and gave a salute.

"Hmm. It's almost time, I'm offline. You are responsible for helping me manage my body. ”

A few high-ranking Mona who followed behind Green: "Mona! ~”

In the next moment, Black Mona Green fell to the ground like a robot without power.

……

On the surface world, Green opened his eyes.

It's dawn.
