With Agatha's ability to fly, the two of them moved very quickly. Klein estimated that Agatha's flight speed was at least 200 kilometers per hour in a high altitude, which was much faster than the turtle speed of the train.

After more than three days of flying, the two finally arrived at the western mountains, the Crodian Mountains, and the highest peak of Crodian is the legendary top of the world, Elilujah.

Hovering around Ellilujah, Agatha couldn't help but sigh.

"I didn't expect to finally return to this place, it's so high!"

"What's so good about Gao? It's so cold here, why don't you continue flying?"

At Klein's urging, Agatha had to fly towards the top of the mountain, but the final peak was too high and the wind and snow were too heavy. At the last part, Agatha could no longer maintain the flight and lost balance and fell from the air.

Seeing that the situation was not good, Klein immediately stretched out more than a dozen bone blades and nailed them to the ice wall, and several other bone hands grabbed Agatha.

It was finally time to come here. If Agatha died, his plan to see the ancient ruins would be shattered.

With the help of these bone blades, Klein climbed upwards like a spider. This difficult-to-climb top of the world is simply not difficult for Klein with the assistance of the extension of bones.

In just a few minutes, Klein took Agatha across the last mountain road and climbed to the top of the mountain.

The top of Aliluja is not sharp, but a huge platform. It is precisely because of this that more than 300 people were able to live here.

There is also wind and snow on the top of the mountain, but after the wind and snow enter a certain range of the top of the mountain, it will be automatically separated.

"I didn't expect that there was such a place like a paradise that looked like a deserted place for a long time.

However, the barrier here is still maintained, and I don’t know how many years it has existed and what its power core is.”

While studying the barriers of Elylujah, Klein made records in the book of Klein.

Agatha looked at Klein who was carefully recorded and unexpectedly said.

"I don't know that you like research!"

Klein glanced around and spoke again.

"Of course, although these studies cannot improve my hard power, they can improve my soft power. When there is enough soft power, or under certain specific conditions, it will become hard power, do you understand?"

"Soft power and hard power?" Agatha murmured.

Klein's skeleton had roughly explored the surroundings and reported to him.

"There are no corpses here. At this temperature, the corpses will not rot and should have been thrown down the mountain."

Speaking of this, Agatha's face became a little dark. Of course, she knew that the body Klein mentioned was from her former tribe and her biological parents.

Klein saw Agatha's expression unhappy, as if he was immersed in sadness, and immediately interrupted. The tool man is the tool man, and at this time he must do the work that the tool man should do!

"Okay, the emotional topic is over. It's time to do some serious business. Do you have any impression of this place?"

Agatha was speechless, can’t even recall the past?

"I was just born shortly after I was taken away. How much impression can I have? You think of the Dragonborn Awakening too strongly."

"What about the key? What is the way to open ancient ruins?"

"How do I know?"

"Cialia said before that the keys cannot be taken away, so they left the keys here. Think about it, where is the easier place to hide things?"

"Hide something?" Agatha frowned and began to think.

Instead of disturbing her, Klein summoned a large number of skeletons again and began a carpet-style search of the entire mountaintop.

I have to say that skeletons are really useful! They are even more skilled in finding things to explore.

Summoning is super cheap, not afraid of pain, not afraid of cold or heat, in harsh environments like Ellilujah, skeletons can work normally.

And you won’t be afraid of death. Apart from the weakness of strength and weakness, it requires magic to control it, there are basically no shortcomings.

Because we have to speed up the progress and the environment here is quite complicated, Klein summoned 30 first-level skeletons at one time, which is not a battle, and his strength does not need to be too strong. First-level skeletons are completely enough.

All the skeletons started to rummage over the cabinets on the top of Mount Ellilujah, and basically everything they encountered would be stirred up Kang Kang!

Agatha, who was standing beside her, felt more and more uncomfortable as she looked at her, and she couldn't help but say.

"This is my home! Can you restrain yourself?"

"I ask you, you don't know the situation, how to find constrainedness? And why do you still need to be constrained? Do you want to live here in the future?"

Klein was not angry. Although this place is very fairy-like, it is difficult for people who truly enjoy life to live in this environment.

Although Agatha is a dragon descendant, she is also a lady who grew up in the Plodyni family. Klein doesn't believe that Agatha can live here.

"Okay, stop looking for it, I probably know where they put the keys."

"I'll say it earlier. I won't go back to your house if I'll say it earlier? Brothers, I'll finish the work!"

Under Klein's command, all the skeletons stopped their movements and came to the center of Ellilujah.

Clein followed Agatha to a small but thoughtfully decorated cottage.

Looking at this, Agatha showed some reminiscence.

"I should have been born here. I remember when I was about the full moon, my father took a gold sign from a secret wall in the room for me to play with.

If there is any place suitable for hiding things here, that dark square is definitely one of them."

Speaking of this, Agatha walked straight towards the most inconspicuous white wall in the room.

She placed her palm in the center of the wall and pressed it hard. After a long time, Klein thought she had made a mistake, and a part of the wall suddenly began to sink, revealing a small dark square.

"It's true here."

Agatha took out a piece of iron from the dark grid, which was more like a dragon-shaped amulet than a key.

"This is the key?"

Agatha said with great certainty.

"Although I haven't seen it once, as soon as I touched this thing, I was sure that this was the key."

Klein took the amulet from Agatha's hand, and he was a little curious about why those who said that they could not take the amulet with them.

So Klein ran out with the amulet, but after a few steps, he already knew why the other party had not taken the amulet away.

As he approached the barrier, the amulet began to become heavier and heavier. Klein could hardly hold it when he was still far away from the barrier.

Klein had no choice but to take Hui Talisman back in shame.

"I'll give it back to you. Now the key has been found. What is the legendary ancient ruin? What kind of way is needed to open it?"

Agatha shook her head, too.

"I really don't know this!"

There is no way, I don’t know and I can’t force it. I’d better find it myself! Klein waved his hand at the thirty skeletons parked in the center.

"Friends, it's time to work!"

Agatha stopped Klein.

"Why did you let them act again?"

"You don't know where you are, so don't let them look for it. When will we find it?"

Agatha knew that Klein made sense, but it was definitely difficult to accept psychologically.

"If you don't want to be overturned for too long, you'd better think about where that ruin is."

After saying that, Klein took out the mechanical hive. This kind of exploration, the worker bee is the best help. The ground can be handed over to the skeleton, but the sky cannot.

8 worker bees began to surround the barrier, touching and trying where the boundary of this barrier was.

After some exploration, the ground has been completely explored by the skeletons, and the barrier at the top has been completely viewed by the worker bees. It is indeed a semicircle and there is nothing special.

"This is unscientific!"

Klein began to circle around the top of the mountain. After walking to the Dragonborn clan hall, he found a missing place.

Behind the Dragonborn Hall is a cliff, and this cliff area is also a place where the barrier is shrouded. His worker bee has only explored the top, but has not explored the bottom.

Agatha was thinking about the ruins, but found that Klein had climbed onto the roof of the Dragonborn Hall.

"Klein, what are you doing?"

Klein ignored him and looked down from here, and couldn't see the bottom at all. At the height of Ellilujah, if this cliff was at the end, it would be impossible to blow the abyss.

Klein would definitely not do this by himself. He sent all the worker bees to the point where they began to touch the barrier. Finally, on the barrier wall near the abyss, the worker bees found a hole.

This barrier is actually extending outward. If there is no trick, the ghost will not believe it.

Klein asked the worker bees to fly into the passage, but as soon as they flew over, the worker bees lost contact, the second and third ones were the same.

"Something! Agatha, come here!"

Agatha was confused when she heard Klein calling her and hurried over.

"You found it?"

"I found a place, but I don't know if it is!"

Klein took Agatha to the roof of the Dragonborn Hall, which looked down here and was no different, but Klein pointed out one direction.

"There is a passage about 3 meters in diameter at that location, which is very strange."
