Look near the mountains, there are many entrances to the underworld.

Soon a tunnel entrance was found sloping downward, and judging by the traces of the doorway, it was a place where people had set foot.

Entering the tunnel, it was inclined down for hundreds of meters.

The air became humid and cold, and the smell of bat droppings was in the air.

In this kind of dark underground, it is very easy to get lost without enough experience or preparation. Roy and the two cat maidens are proficient in spatial magic, and if they get lost, they can directly teleport to the surface.

Roy stopped, raised his hands, and chanted softly, a pale white ball of magic light condensed in his hand, and the magic fluctuations spread out on this ball of light, wave after wave.

The team members all looked at Roy curiously.

They don't understand what the hell the Demon King is doing?

Lolina thought of something, clapped her hands and said:

"Young Master, are you using magic fluctuations to locate you?"

"Well, remember what I told you about the sonar system?"

"Uh-huh, use sound localization."

The two cat girls nodded and recalled.

Roy goes on to explain:

"This thing works similarly to a sonar system, with mana fluctuations for positioning."

It's a stupid thing to actively emit mana fluctuations.

Because creatures who know magic can easily catch these fluctuations, like a big light bulb in the night. There's no need to hide your location now, and Roy can't wait for someone else, or a monster, to come to the door.

The distance of the mana fluctuation diffuse feedback is about more than 1,000 meters.

The complex network of caverns like cobwebs underneath was presented to Roy.

It was about 200 meters down.

Underground vegetation began to appear, all of which were mushrooms and mosses, and most of these underground plants would glow and the burrows would be bright.

After walking for a distance, suddenly there was a sound of digging in the wall, and everyone was alert and alert to the source of the sound.

The earthen wall was broken.

A large insect 2 meters tall, pitch black, with multiple accessory limbs, broke through the ground.

It screamed in horror at the crowd.

"It's noisy, tuba is online."

Roy replies to the prototype.

"The breath of fire, the wind of vitality"

Open your mouth and breathe.

Stimulated by the wind of vitality, the flames turned blue-white.

The black bugs writhed in the flames, but they didn't die. Its dark and shiny exoskeleton gave it a high level of elemental protection, and the flames could not help it, and the black beetle made a sizzling sound, as if mocking Roy's magic attack.

Roy squinted, ready for the next spell.

"Extremely frozen."

Luo Yi did not unfold the six-element magic array, the release speed was slower, and a burst of ice-blue freezing air blew out, covering the surface of the insect's body.

The black beetle that was laughing at everyone didn't move, and the moment the ice mist touched it, it seemed to be immobilized by a spell, and only two compound eyes flickered.

Under the rapid heat and cold, it felt that the exoskeleton that it was proud of had undergone extremely terrifying changes. The slightest shock from the call may be the end of smashing.

Roy winked at Barnard.

The little milk dog snorted, entered the battle mode, directly became a brother, and strode in front of the black beetle.

The black beetle shook its head slightly.

Barnard grinned, swung his punchbag-sized fist, and slammed it into the black beetle's chest.

Click.

A crack spread.

Seeing this, the black beetle breathed a sigh of relief, it was just a crack, and it was acceptable.

It leaned triumphantly at its tentacles.

Ye's exoskeleton is the hardest, and when he recovers from the damn Wen Zhen, he will shred you two-legged reptiles!

The black beetle dances its tentacles and sends out a signal to show off its might.

None of the seven people moved, just staring at the black beetle.

After a delay of a few seconds.

Click!

The black beetle exoskeleton completely shattered, turning into pieces the size of ping-pong balls and shooting out in all directions. A big fat insect with white flowers and whirring flesh fell to the ground and looked at everyone stupidly.

With a squeak, the big fat worm wriggled and disappeared into the hole it entered.

Roy touched his chin and said:

"Aren't these underground insects, exoskeletons and flesh one?"

Elena said:

"This thing is called amoeba and the exoskeleton is made by them from their own secretions and can mimic other types of bugs. The best way to kill them is to attack them when they take off their armor. ”

Roy's brain made up the scene of the amoeba sleeping and undressing, taking a shower and undressing......

"Grab a few and go back to study."

Loy gave the order, and Suya and Barnard rushed into the tunnel.

After a while, he dragged the bug back.

Roy directly teleported the bug to the gate of the Demon King City and posted a note for Gina to study carefully.

The ground is full of all sorts of wonderful things.

Plants, animals, minerals, etc., a large box was collected and sent back to the institute.

Many science and technology imitate biology, and the development of science and technology is often limited by various materials. Therefore, studying creatures and studying all kinds of strange materials is very helpful for the tech tree to climb.

Three days of aimless action.

In the process, I met many adventurers, but I couldn't find the brave.

During the time when the demon king was raging, there were not many brave people who came to train.

Roy thought twice and decided to get out of the underground. According to the original plan, advance to the northern front.

On the morning of the fourth day, he returned directly to the surface through teleportation magic, returned to the Black City, bought the day's ticket, and continued north.

The closer you get to the north, the more news of the war.

The water became wider and wider, and in addition to merchant ships, a large number of military ships began to appear, transporting troops to the north. Staying close to the city on the edge of the front line, you can feel the subtle change in the atmosphere. The topics of discussion around me were mainly focused on the war.

"You've heard that last month, the Temple of Courage gathered more than 30 braves, 3 top braves led the team, and 27 high-level braves went to crusade against Simba, but it still failed."

"The legendary-level demon king is really terrifying."

"Simba also refused to redeem the request, and at the forefront of the war, he killed 30 brave men in front of everyone, and the army pressed the border and directly captured Fort Dorieux, and our Dono is in trouble."

"Will it be like the Dark Ages 700 years ago, and finally turn into a war that will engulf the world?"

"The Temple of Courage has summoned representatives of all countries, representatives of all races, and the Apostles of the Temple of the Twelve to discuss this matter, this year has not been easy~"

"God of Light, please bless your believers." ……

The hotel was full of people.

The war in the north is urgent, and the mercenaries are gathering to the north, and there are quite a few people here.

Roy and his party sat around a table, listening in silence, occasionally exchanging two words. Roy drank the blazing wine in his glass and asked the bartender for a glass of Fat House Happy Water with ice.

"Children have a good amount of alcohol, this flame wine is not something that ordinary people drink after. This is your fat house happy water, the first time and to slow down, don't choke. The bartender gave a thumbs up.

"I've drunk it."

Roy smiled, picked up the fat house happy water with ice and took a big sip.

Migaka will moisten things silently and have already sold their products here. It's just that because the war in the north is urgent, no one is discussing the changes in these daily necessities.

"Our peers are really amazing."

"The legendary demon king must be an old man."

Lolina whispered in Roy's ear, and Lilina nodded in agreement.

Suddenly, an obscene voice came:

"Beauty, then you're wrong. Simba is a handsome guy, although he is a demon king, but he is indeed the prince charming of a young girl, what do you say is this? Hehe, do you want a drink, I'm in for a treat~"
