By the altar, Lu Feng scanned the surroundings with a serious gaze.
Of the four stone pillars serving as the eyes of the formation, one was already broken, and the runes carved on it were also dim and lusterless.
He squatted down, fingers lightly touching the fracture, sensing the residual aura of the Deep Abyss, exactly the same as the energy in the sky rift of the Extreme North.
"It really was its doing," Lu Feng muttered to himself.
The Deep Abyss Spirit Dragon had lurked for unknown years; even a formation left by a deity could hardly withstand the passage of time.
Now, although the Deep Abyss Spirit Dragon had been killed, if this formation couldn't be repaired, the rift in the sky of the Extreme North would inevitably grow larger and larger.
At that time, perhaps before God King Tang's ten-thousand-year grand plan could be executed, the Deep Abyss Plane would invade ahead of schedule.
Xiao Wu tugged at Lu Feng's sleeve uneasily. "Lu Feng, do you have a way to repair it?"
Lu Feng didn't answer immediately but surged his soul power, taking out the Ice Soul Sword from his Sea of Consciousness.
As soon as this crystal-clear long sword was unsheathed, the surrounding temperature dropped instantly. The cold air flowing on the sword blade condensed into tiny ice crystals in the air.
"I can only give it a try."
Lu Feng took a deep breath and injected soul power into the Ice Soul Sword.
Lu Feng didn't know the principle of this formation, but he had studied the mutual generation and restriction of the Five Elements. Within the Five Elements, as long as there was any one attribute, the other four could be derived.
What Lu Feng was doing now was attempting to stimulate the power of the formation itself.
The Ice Soul Sword was inserted into the ground. As Lu Feng's soul power poured in, the sword blade instantly shone brightly, an ice-blue light pillar shooting straight into the sky.
A layer of ice-blue mist scattered rapidly towards the surroundings.
The remaining three stone pillars were instantly frozen, and the inscriptions on them began to shine with golden light.
"Eh, seems it really has an effect!"
Xiao Wu was surprised to find that as Lu Feng circulated his power, the fragments of the broken stone pillar actually began to tremble slightly.
At the location of the broken stone pillar, newly carved runes appeared one by one, emitting a soft blue light.
"Huu."
At this time, fine beads of sweat began to seep from Lu Feng's forehead.
He originally just wanted to try, not expecting it to really work. But a new problem came; the soul power consumed to repair the formation far exceeded his imagination.
In just over ten minutes, Lu Feng felt more tired than fighting the Deep Abyss Spirit Dragon. If not for his soul power breaking through to Titled Douluo, he probably wouldn't have been able to hold on.
Lu Feng bit his fingertip, and a drop of blood containing divine power dripped onto the Ice Sword.
"Buzz—"
The entire altar vibrated violently.
Three stone pillars lit up with dazzling light simultaneously; even that broken stone pillar was reconnected by blue light.
The turbulence in the sky was gradually dispersed by the pure ice-blue energy.
"Success!" Xiao Wu cheered.
Immediately, she came to Lu Feng's side and asked with concern, "Lu Feng, are you okay?"
Lu Feng's state looked somewhat bad at this time, face pale, forehead full of sweat, looking like he would collapse at any time.
"Look at me, do I look okay?" Lu Feng said speechlessly.
Xiao Wu stuck out her tongue. At this time, she looked at the Ice Sword inserted in the ground and asked doubtfully, "This sword, just leave it here?"
This was a divine artifact. Xiao Wu only obtained an Asura Sword Scabbard, but she had fully felt the power of a divine artifact.
Nourished by divine power, although she was in a soul state now, in terms of strength, she was not inferior to an ordinary Soul Saint at all.
Lu Feng nodded. "The Ice Soul Sword originally belonged to Azi; let this sword accompany him forever."
"Who is Azi?"
A smile curled up at the corner of Lu Feng's mouth. "The master of this place, the Ice God, my sworn brother."
"Heh." Xiao Wu snorted lightly, obviously not believing Lu Feng's words.
Changing the subject, she asked doubtfully, "Now, how should we get out?"
Lu Feng shook his head. "This place is too far from the continent; my Four Symbols Formation cannot traverse space to return."
"Ah? Then wouldn't Sister Xiao Wu have to stay in this place for a lifetime?"
Lu Feng didn't answer but came to the middle of the altar.
Just when repairing the formation, he already vaguely understood the usage of this set of formations.
Eighteen formation eyes were the most important passes of the continent in ancient times, each heavily guarded.
Each pass allowed no loss; therefore, teleportation could be carried out between each formation eye.
Lu Feng's soul power surged, and the Asura Sword appeared in his hand.
He turned to look at Xiao Wu. "Rabbit, combine."
Xiao Wu curled her lips. Although somewhat confused, she still followed what Lu Feng said, emitting a burst of pink light all over.
The next moment, Lu Feng turned into the state of Asura God Outfit again.
"Clang~"
As Lu Feng's divine power was displayed, the entire altar suddenly burst out with a dazzling intense light.
The next moment, a spatial vortex suddenly appeared around Lu Feng.
When vision became clear again, a strong smell of blood rushed to his face. Lu Feng looked around vigilantly: dark red sky, magnificent palace.
Red light flashed, and Xiao Wu returned to her soul state. "Capital of Slaughter? We really came back?"
Lu Feng nodded. "Mhm, the two formations are interconnected."
He tried to sense the soul power in his body, finding that although the consumption was huge, there was no major problem. "Let's adjust our breath first, then go settle accounts with the King of Slaughter."
Meanwhile, in the Extreme North.
Snow Empress and the other two looked up at the gradually healing sky rift, their faces written with disbelief.
Ice Empress rubbed her eyes, afraid she saw wrong: "The rift... is really disappearing?"
"Roar!" Ah Tai beat his chest excitedly, emitting a sky-shaking roar. "Did he do it? That human named Lu Feng?"
Snow Empress was silent for a moment, then said softly, "But the rift disappeared; can he still come back?"
As her voice fell, the three fell into a brief silence.
Snow Empress suddenly raised her hand, and a pure ice-blue light shot straight into the clouds.
Her solemn voice echoed throughout the Extreme North: "From today on, the name of Lu Feng shall be sung by all soul beasts in the Extreme North."
Ah Tai nodded heavily: "Although I have never seen the Ice God, in my heart, he is the Ice God! Or we should erect a stele for him. No, a temple!"
Snow Empress rarely showed a smile: "Carve his statue with ten-thousand-year mysterious ice, so that future generations will remember forever."
Inside the Capital of Slaughter, Lu Feng, who was adjusting his breath, suddenly opened his eyes.
He was surprised to feel a warm and powerful energy pouring into his body, and his originally exhausted soul power actually recovered instantly.
"What is going on?" Lu Feng muttered in surprise.
Xiao Wu looked at him curiously: "What's wrong?"
"Don't know." Lu Feng's eyes were solemn.
Although it was a good thing, he always maintained a sense of reverence towards unknown things.
"Power of faith, seems to come from the Extreme North," Lu Feng said uncertainly, gripping the Asura Sword and feeling the surging soul power in his body.
"Could it be that Snow Empress and the others know about what you did?" Xiao Wu asked doubtfully.
"Forget it." Lu Feng strode forward. "Let's go kill the King of Slaughter first."
