However, he also discovered a problem. After reaching tier-6, the effect of the crystal seemed to have weakened.

Su Han shook his head. No matter what, this crystal was the first product that he could find to replace the magic core.

After reaching tier-4, absorbing the power of a tier-3 magic core was no longer of much use. However, if he continued to absorb the power of a tier-4 magic core to complete the rapid realm like before, the difficulty would be unimaginable.

Magic nuclei that could reach tier-4 and above were rare to begin with. Moreover, to become a tier-7 mage…

He would need at least 400,000 spiritual power.

If he were to increase the power using a tier-4 magic nucleus by 1,000 points, he would need at least 200 magic nuclei!

That would be 200 tier-4 magic beasts! Tier-4 magic beasts could be considered lords of a region. They would definitely not gather together like low-level magic beasts. It would be extremely difficult to advance by relying on magic nuclei.

Su Han returned home and quickly searched for relevant information.

Very soon, he found the blue crystal from some magic books with similar records.

“The ore of the Land of Eternal Freezing, also known as the Breath of the G.o.ds…” Su Han read the records in the books word by word.

“Legend has it that in the distant polar region, pa.s.sing through the territory of the Barbarians and the Northern Elves, there is an unfreezing spring flowing down from the Divine Realm at the end of the continent. The power in the spring gradually condensed into a blue ore after years of acc.u.mulation. This ore is regarded as a sacred object by the Northern Elves and Barbarians. They believe that it is a gift from the G.o.ds and have been guarding the polar region for a long time, voluntarily becoming the guardian of the frozen earth.”

After Su Han finished reading, he touched his chin.

In other words, this type of ore was the source of power for the Northern Elves. Then, was the soul in the soul bead also a soul that was nurtured from that type of ore?

Su Han closed the book and stood up. He already had a plan in mind.

It was time to go to the Northern lands. If he could obtain a large amount of blue crystals, becoming a tier-7 mage would be a very simple matter.

Soon, it was evening.

He did not know where Xiao Yu'er had gone, but with Little Purple following her, she should be fine.

Just as he was about to meditate, there was a knock on the door.

Su Han's eyes widened when he saw it. He did not expect Ruth to find them. Did she discover his ident.i.ty?

He opened the door and said with a smile, “Niece, why are you in the mood to visit Uncle today?”

Ruth's face was solemn. She looked around and was very vigilant. She quickly walked in and closed the door.

Su Han saw her vigilant look and didn't know whether to laugh or cry. He said, “What are you doing?”

Ruth looked at him solemnly and pulled him to the front of the chair. She said in a heavy voice, “Little Uncle, did you hear about what happened this morning?”

Su Han was slightly stunned. He knew that she was referring to the Northern Elves. He shook his head and said, “I've been meditating at home and didn't go out. What happened?”

Ruth took a deep breath and said, “The Executioner appeared. He also helped us deal with the five Northern Elves who attacked us. One of them is at least at the peak of tier-7.”

Su Han was shocked and said, “You mean, Senior Brother Duke Kao…”

Ruth nodded and said seriously, “I thought he was very strong, but he wasn't that strong. But today I found out that if he was serious, even a tier-7 elven mage could not easily crush him…”

She lowered her eyes and said, “Now I finally found out why your teacher had to ask my G.o.dfather to do it himself. His strength is simply unfathomable. Why is everyone in your lineage a monster?”

Su Han rubbed his nose awkwardly.

Ruth glanced at him and said, “You're still considered normal.”

Su Han looked at the ceiling and said, “Is that so?”

“Aren't you worried that your Senior Brother Duke Kao will come to kill you?” Ruth frowned and said, “If he wants to kill you, it's as easy as flipping his hand. Even if I'm by your side, I can easily be crushed by him!”

Su Han held his chin and thought, “Senior Brother Duke Keo and I used to have a good relations.h.i.+p. Perhaps, he won't kill me!”

“Silly!” Ruth stood up and said solemnly, “You're not him. How can you know that he won't kill you!? You must think of the worst case scenario! What if he comes to find you tonight?!”

Su Han said helplessly, “Then what should I do? Don't tell me I have to run away!”

Ruth took a deep breath. She waved her hand and an exquisite protective scroll appeared in her hand.

She said solemnly, “Take this. If he really comes to find you, crush it. It contains a high-level teleportation spell. As long as you crush it, it will immediately teleport you several kilometers away. It can protect you at least once!”

Su Han was stunned and said, “You want to give it to me?”

Ruth nodded and said, “My G.o.dfather entrusted you to me before he left. If anything happens to you, as the guardian, I can't escape the responsibility.”

Su Han widened his eyes and said, “You should keep this thing for yourself…”

“Take it if I tell you to!” Ruth hung the protective scroll around Su Han's neck without any explanation. She thought for a moment and felt that it was not safe, so she took a bracelet from her wrist.

Su Han immediately shook his head and said, “I don't want jewelry!”

Ruth stared at him, she said, “Let me tell you, this bracelet of mine is a magic conductor that my mother brought with her when she married from the Imperial Capital. It has a history of a thousand years and was forged by the most outstanding craftsmen of the dwarves. After you wear it, it can at least block several tier-6 spiritual attacks for you!”

She put it on Su Han's wrist without any explanation.

Su Han was speechless. He was about to say something when Ruth patted his shoulder and said seriously, “If the Executioner comes to find you, don't hesitate and run away immediately. It's not shameful.”

After she said that, she turned around and left.

Su Han looked at her back as she left. He wanted to say something, but he laughed and shook his head.

Ruth's temper was exactly the same as Luberg's. Although she looked cold, she valued relations.h.i.+ps very much. He really felt bad for lying to her.

As expected of Teacher Luberg's biological daughter. It was just that the relations.h.i.+p between the father and daughter was not good.

“It's fine. It's just lying to my own niece!” Su Han muttered.

He didn't know that with these things, his trip to the North would have more security.
