Arriving at her destination without incident, and having a good night's sleep by the way, McGonagall was in no hurry to wake up the mother and daughter who were still asleep, changed into a chef's uniform, and went to the kitchen to make breakfast.

The fridge doesn't have a lot of ingredients, but it's quite complete.

McGonagall boiled a pot of porridge with preserved eggs and lean pork, and made another fritter.

"How did we get underwater?" Irina led Amy to the kitchen door, looked at McGonagall who was scooping fritters and asked with some confusion.

"I've seen a lot of fish, Father, are we going to eat grilled fish at noon today?" Amy asked, her eyes lit up.

"It's harder to be spotted underwater, we're already near the black fog." McGonagall answered Irina's question first, then looked at Amy and nodded, "If Amy wants to eat, then let's eat grilled fish at noon." ”

"Okay!" Amy nodded happily.

"Black Mist." Irina walked to the edge of the dining room and looked out through the transparent wall, quickly noticing the surging black fog in the distance, and although she was hundreds of meters away, she still felt the aura of death that disgusted her.

"Let's have breakfast first, we'll go check on the situation after breakfast, this black fog is bigger than I expected, and we need to know where we are now." McGonagall looked at Irina and said.

"Hmm." Irina nodded, took Amy to wash up, and ate McGonagall's freshly cooked breakfast.

After breakfast, everyone came to the central control room, McGonagall canceled the hosting mode, manually drove the mobile restaurant in the direction of the black fog, and stopped a hundred meters away.

After getting closer, the surging black fog can be seen more clearly, and the black fog as thick as black ink makes people feel bored for a while just looking at it.

"Shall I just remove it with the Light?" Irina asked.

"Let me find out first." McGonagall shook her head, swiping her finger across the screen, bringing up the amphibious drone and clicking to launch.

A small submarine in the shape of a water drop ejected out and drove silently towards the black fog, and soon the picture transmitted by the submarine appeared on the big screen in the central control room, and all kinds of fish were clearly visible.

The ugly duckling lay in front of the screen, stretching out its fat paws to try to grab the fish and stuff them into their mouths.

"Is this your new pet?" Irina looked at the picture with some surprise, it was the first time she had seen a Warcraft that could transmit the picture back remotely like this.

"Sort of." McGonagall nodded, he didn't know how to explain the presence of this high technology.

When the submarine entered the black fog, the picture suddenly turned black, but the camera mode was quickly changed to infrared mode, and in the surging black fog, there were still all kinds of marine fish.

However, their appearance and skeleton seemed to have some strange mutations, with sharp teeth, and frantically attacking and devouring each other in the black mist, McGonagall saw an oversized crayfish and used its large pincers to clip off a moray eel, and a number of fish attacked the small submarine, but it was easily avoided by the speeding submarine.

"These fish look scary." Amy curled up in Irina's arms, a little scared.

"Is it because of this black fog?" Irina looked at this scene, her face was also a little solemn, and those fish that were frantically devouring each other seemed to have lost their minds.

"Most likely, it seems that the impact of this black fog is even more serious than we thought." McGonagall also nodded solemnly, the current black fog is only a few hundred meters in radius, and the only thing affected inside is a school of sea fish, if the area of the black fog expands and covers some powerful races, the consequences will be unimaginable.

The small submarine soon docked, and a bamboo dragonfly-shaped propeller appeared at the upper end of the water droplet, silently rising into the air and opening the aerial photography mode.

This small island is not large, it is an irregular circle, less than a thousand meters in diameter, and the black fog has enveloped the entire island, and it spreads in all directions around the small island.

Through the infrared camera footage, you can see that there is a group of monkeys on the island, and like a school of fish on the bottom of the sea, the monkeys are also caught in cannibalism, and the mutilated corpses of monkeys can be seen everywhere, several of them have reached a height of three meters, and after devouring each other, these monkeys seem to have evolved.

"It looks like it's an uninhabited island." McGonagall whispered, it was the only thing that comforted him, preparing to retrieve the drone.

"Father, look, there's a big round fat man there." Amy suddenly pointed to the bottom right of the screen.

"What is this?" In the picture, only a vague circular figure can be seen, turn the camera, zoom in on the screen, and a big fat man kneeling in front of a stone statue does appear in the center of the screen, because it is too round, like a round ball.

And the stone statue could only see a rough outline in the thick black fog, which seemed to be skeletal-shaped.

"This size may be a demon of the Abyss Demon Clan." Irina leaned forward slightly, judging.

"Our current location is 350 miles west of Abyss Island, and it is still within the sea area of Abyss Island, so it is indeed possible that it is an Abyss Demon." McGonagall glanced at the map and nodded in agreement.

When the Demon Clan and the Dragon Clan were in peace before, he had received the Abyss Demon and was deeply impressed by the big fat man riding the pig.

And in that ambush that year, the Abyss Demon Clan was also one of the leaders, and Irina's must-kill list for this trip included the Abyss Lord Alfred.

I thought it was an uninhabited island, but I didn't expect that the Abyss Demon was involved, which made this black fog removal operation change abruptly.

"He seems to be saying something, maybe we can know from him what happened to Berg in the first place." McGonagall turned up the drone's stealth to the maximum, then slowly approached the sound.

Relying on the shelter of the trees, the drone soon approached the vicinity of the abyssal demon, and a dream-like sound gradually became clear.

"I ...... Alfred...... Serve the Master...... Strength...... Give my soul ......" The drone stopped more than ten meters away, and the ball of flesh like a hill could be seen, and his intermittent words surprised both McGonagall and Irina at the same time.

"I didn't expect it to be Alfred, who gave his soul and gained power, is he making a deal with the devil?" Irina frowned.

"What is a deal with the devil?" McGonagall asked, puzzled.

"It's an old legend that fallen creatures sell their souls to the devil to gain terrible powers, and that's a deal with the devil." Irina said softly.

"I'm afraid it's not just a legend." McGonagall looked at Alfred, whose body was gradually expanding at the end of the sentence, and said with a solemn face.
