Su Han quickly floated up and flew toward the warehouse.

Along the way, the barbarian soldiers gave way one after another and gave their Great Chieftain the most n.o.ble courtesy.

When they came to the warehouse, the barbarians inside were counting the materials. The green crystals were emitting a bright light.

“You guys can leave. No one is allowed to come in without my order.”

“Yes, Great Chieftain!”

The barbarians left and closed the door of the warehouse.

Su Han looked at the green crystals and took out the Soul Bead. When he felt the intense energy fluctuation, the spirit appeared again. With a cheer, it rushed to the front of the crystal.

Su Han smiled and said, “There are many here. If you are hungry, you can absorb them.”

The spirit let out a cheer and revolved around a crystal. The crystal immediately turned into a light spot and fused into her body.

Su Han stared at her body without blinking. His breathing slowly quickened. The wheel of law was flas.h.i.+ng in her body bit by bit.

If he could master this method of purification, then the breakthrough of his spiritual power that troubled him would be easily solved!

“This is…” Su Han's eyes suddenly widened. A brand-new wheel of law was constructed in his hand.

He could not help but laugh and said, “The highest level energy conversion method of the Northern Land Spirit! Very good!”

In the next moment, he integrated the wheel of law into his body.

[Ding! You have absorbed the Tier-3 Wheel of Law, Purification.]

Su Han smiled, picked up a crystal, and handed it to the spirit, saying, “Eat another one!”

The Northern Spirit let out an ethereal echo, expressing its joy. The crystal in Su Han's hand was quickly absorbed by it.

Su Han suddenly stretched out his hand, and a new wheel of law was formed.

“This is a coherent rule. Only when used together can it reach the height of the Northern Spirit.”

[Ding! You have absorbed the Tier-3 Wheel of Law, Compression.]

“Eat another one!” Su Han laughed.

“En…”

[Ding! You have absorbed the Tier-3 Wheel of Law, Energy Conversion.]

“One more!” Su Han laughed.

“Separate…”

[Ding! You have absorbed the Tier-3 Wheel of Law, Refinement]

All the law wheels had been absorbed.

Su Han immediately floated above the crystal and looked at the resplendent crystal beneath his feet. He suddenly stretched out his hand.

His spiritual power was activated, and the wheels of laws were constructed. Purification, refinement, compression, and energy conversion.

These four wheels of laws were a set of combinations that interacted with each other. If they were constructed according to this sequence, they would be able to perfectly simulate the absorption methods of the Northland Spirit Soul.

No matter what kind of energy the Northern Land Spirit Soul absorbed, it would be able to increase the strength of its own soul. In other words, it was constantly evolving.

“Finally, it's time to devour, absorb, and accelerate!”

In the next moment, 2,000 crystal stones burst out with dazzling light. In an instant, they turned into countless light spots that surged towards Su Han's body.

A large amount of energy was purified and transformed over and over again. Finally, it turned into the purest energy and was absorbed by Su Han.

He could clearly feel that his spiritual power was still increasing step by step.

In the next moment, he rushed out of the warehouse and flew into the high sky. He could not help but laugh.

“This transformation method is indeed correct! It seems that I succeeded!”

He opened his attribute panel.

[Name : Su Han]

[Race : Human]

[Mage Level: Tier-3 Mage]

[Secret Trove: 2]

[Physical Fitness : Tier 170]

[Mental Strength : 31,100 points]

[Blood Qi: 34,000 points]

[Tier-3 Wheels of Law: s.p.a.ce Opening, Cold Resistance, Cooling, Strength, Hardening, Energy Conversion, Compression, Purification…]

[Tier-4 Wheels of Law: Soul Destroying]

His spiritual power had increased by a thousand points.

This increase might be insignificant to him at the moment, but it had opened up a whole new path of improvement. A high-level magic core was no longer his only option, even if he did not have a high-level magic core or high-level minerals, he could still improve rapidly.

He quickly took out the ring that stored a large number of tier-1 and tier-2 magic nuclei.

Thousands of magic nuclei floated in the sky, s.h.i.+ning under the sun.

The barbarians outside the fortress all raised their heads and looked at the Great Chieftain floating among the countless magic nuclei, revealing a stunned and respectful expression.

In the next moment, they were shocked to see the countless magic nuclei turn into countless fine light spots, rumbling and surging toward their Great Chieftain's body.

That violent energy fluctuation had actually formed a whirling tornado with Su Han as the center.

“That… That is…” Frida looked at Su Han in the sky in shock.

She had never seen such a terrifying absorption ability. Moreover, she could clearly feel that their Great Chieftain's spiritual power level was increasing bit by bit.

“Great Chieftain Su Han, could it be that you can use low-level magic nuclei to increase your spiritual power upper limit!?”

Frida looked at that scene in disbelief, feeling her heart beating uncontrollably.

“I need more magic nuclei!”

Su Han's voice in the sky echoed throughout the entire fortress like thunder.

Ensai rushed out of the fortress and looked at Su Han who was in the vortex in the sky in shock. He obeyed Su Han's orders unconditionally.

“Quick! Everyone put down the work in your hands!” Ensai roared, “Bring out all the magic nuclei that we have seized! Bring out all the magic nuclei that you have with you!”

Under the order, the barbarians on top of the fortress began to move. Boxes and boxes of magic nuclei were continuously brought out from the fortress.

The moment they opened the boxes, the magic nuclei floated up one by one and flew towards the sky.

The magic nuclei turned into countless light spots and merged into the vortex formed by the energy.

This scene was like a miracle, causing the hearts of all the barbarians in the fortress to tremble. However, they could not suppress their excitement and pride when they thought that the person in the sky was the Great Chieftain of their human tribe in the North.

This violent energy storm lasted for a full hour.

When Su Han landed on the ground, his eyes were filled with flowing magic light, and all the magic nuclei were absorbed by him.

Maybe tens of thousands, maybe even more.

Although the high-purity energy they could provide was insignificant, it was a qualitative change. With so many magic nuclei added together, it was a great improvement for Su Han.

“Very good.” Su Han revealed a satisfied smile and turned his head to the north.

His gaze seemed to be able to penetrate thousands of miles of land and see the Elven Gate that stood tall in the north.

“Our strategy needs to change.”
