Harem Overlord

The others had many different ways to try to defeat Kai but the most unique one was used by Mia. 

She decided to change the entire battlefield to an ice structure so Kai was forced to fly since the ground would try to freeze him as soon as he touched it.

But the air wasn't safe since ice pillars would randomly raise up and attack him while Mia was throwing a large number of icicles at him.

Even though he was somehow dodging them all, it was still enough to kill many people easily, and the only way they could counter it was if they had a much higher cultivation than Mia.

After everyone was done, Kai spent a week cultivating with all of them separately as all of them reached the Divine spirit realm because of him.

"But after this, your cultivation would slow and even my yang qi can not help you break through a few stages in one session." Kai had told them after their sessions.

After giving them an entire day to sleep, he had spent two more weeks helping them reach the spiritual core realm.

While he was having fu- helping his girls advance in their cultivation, many events were taking place in the elven realm.

The new elven queen was strengthening her alliances with the four other continents while the land of life and death were still secretive.

But after every single one of Kai's girls had broken through to the spiritual core realm, they were ready to move towards the land of death.

"The land of death is ruled by a person named Amon and he was the same person who ruled that place when I first came to this realm. But he is more commonly called the dark emperor because of his mastery over the dark element. He can kill a person by simply looking at them as his dark element would spread over their body and would slowly kill them from the inside.

But with Hela beside him, I am quite surprised that he still hasn't tried to conquer this entire realm. Who knows? Perhaps he preparing some large-scale nasty plot inside the protection of his continent. Even though he doesn't matter to us, we will have to be careful around him when we will go and take Hela back." Kai explained as the girls nodded with determined expressions.

As much as he wanted to leave them behind, he knew that it would neither help him nor them if he did that.

They wouldn't gain any real fighting experience and would depend on Kai to protect them and even though he was happy to do that, he still wanted them to be independent.

As he teleported them on the surroundings of the land of death, he swore to make sure that all of them git out of this safely.

"What is this?" Nezuko asked as they looked at the huge dome-shaped barrier in front of them.

Back mist was gathered on the other side of the barrier and any of them could see what was on the other side of it.

The dome-shaped barrier looked as though it covered the entire continent since it was so huge and wide.

"This is purely made from yin energy. You guys can use this to cultivate and increase your cultivation but it will take you months to do that. We can however do that after we get Hela back." Kai explained as his figure started glowing

Before teleporting inside the barrier, he carefully cloaked them with numerous formations since he knew that Amon would have spread his actual sense across the entire continent.

Amon was at the 5th stage of the Saint core realm and was probably one of the few elves who had such high level of cultivations.

He was ruthless and brutal and didn't think about who he killed or how many he killed. Anyone standing in his way would be killed by him and he had wanted to take control of the entire elven realm.

He had started pressuring the previous elven ruler about that but she and been strong enough to keep him suppressed.

He hadn't known about this until many years later. He had asked her if she wanted him to kill Amon but she had declined him since elves followed the rule that whoever was strong would win.

After this many years, he might kill Amon without actually it being his original mission. As they entered the continent, Kai felt the same aura as last time for a few moments before it vanished.

"We have to be very careful here. This continent is full of extreme amounts of yin energy but it is just suitable for cultivation and can kill a cultivator if they try to cultivate it. Even normal cultivators who use spirit stones to cultivate can die easily if they don't have enough focus. So be always alert." Kai said as they appeared in a forest full of crooked trees.

He decides to walk rather than randomly teleporting into the mouth of danger without any information on what awaited them.

They encountered a few spiritual beasts in the forest but the group was strong enough to them as they continued their progression.

"Kai, are you sure that we are going the right way since your sense of direction isn't really reliable." Mariel said after a few minutes as Kai smiled but didn't stop walking.

"You might not sense it but I have extended my spiritual sense in a wide area to check for any signs of dangers. I know the directions because of that" Kai explained as the group silently released a sigh of relief.

Kai however suddenly stopped as his eyes widened and he frowned. He looked at Risea and silently asked her to come forward.

"We will be back in a few minutes." He said while frowning as they vanished.

"What do you think he sensed?" Riang asked curiously as the others shook their head.

"Probably something related to yin energy since he took Risea because of her angelic powers." Sahara added as the others nodded and patiently waited for Kai.

As for him and Risea, they appeared in a clearing that was full of people. But both Kai and Risea looked at them with wide eyes.

Their clothes were torn and dirty and wounds covered their entire bodies. Frozen blood was visible around the wounds and some looked pretty fresh.

But the people didn't care about the wounds as they walked in a particular direction senselessly. Their eyes were hollow and bloody and their faces were split with horrible wounds.

"They are necromancer elves." Kai muttered as he stared at the dead yet alive elves walking around without doing anything.

But as soon as he said the word necromancy, their ears snapped to attention as they turned to look at Kai and Risea.

Both of them looked at the dead figures with wide eyes as their angelic powers burst forth. Their wings appeared from their backs as they shot beams of light at the undead elves.

But it looked as though they had suddenly gained intelligence as many of them managed to dodge the attack and started advancing towards the duo.

Kai and Risea didn't panic and instead took out their weapons. Risea created a bow while Kai took out Excalibur and wielded the sword with a perfect grace.

He swooped in quickly and with a swing of his sword, he managed to kill many of the undead elves. 

Their number barely summed up to two hundred and they were raise destroyed b Risea and Kai's attacks as they fell down one by one.

Numerous bodies of the undead elves littered the ground as they slowly started vanishing. Only black as remained behind as Kai and Risea looked at each other with grim expressions.

"That was not your usual necromancer. Rarely any undead creatures gain intelligence when their bodies are brought forth but these creatures were capable of detecting noises made by living beings, dodging, attacking, and many more things no undead should be able to do. I only know a handful of people who can do this level of necromancy and Hela is one of them.

However, I didn't feel any aura coming from the undead creature and I am not sure if it was her. But without any information, I can guarantee anything for sure. But if it was someone else, we have got a really fearsome enemy." Kai explained as Risea agreed with him.

The two figures stared at black ash on the ground one last time before Kai teleported them back to the other girls.

In a castle, Esmeralda suddenly opened her eyes with a surprised expression as she licked her lips with interest.

"An entire legion of undead elves killed by someone. Interesting." She said to herself as she stood up from her bed.

She started walking towards the throne room to tell his brother about the most interesting thing that had happened in a while.

Perhaps she would get to see a battle between two powerful opponents.
