Spatial dimension laws were considered very important in the 12 Empyrean Heavens, but they were considered very difficult to learn.

By being proficient in spatial dimension laws, other than Void Tearing, the next stages were… Partitioning the Heavens, Spatial Slash, Void Transference, Teleportation, Refining Independent Spaces, etc!

The higher the difficulty, the more powerful it became. Ignoring everything else, just grasping Void Transference was extremely important in the 12 Empyrean Heavens. This was because the 12 Empyrean Heavens were extremely vast. Even if a peerless mighty figure wanted to travel between two Empyrean Heavens, he would also need to exhaust a great deal of time. By grasping Transference, he could quickly reach his destination.

However, many experts in the 12 Empyrean Heavens were unable to do Void Transference. If they wanted to embark on a distant journey, they would need to use teleportation arrays or sit in spiritual boats that possess Void Transference capabilities.

As for Refining Independent Spaces, the God Advent Tower or Pure Yang Sword Palace’s worlds were both independent spaces. This was an indispensable ability when refining advanced enchanted treasures. There were even fewer people that had such abilities. As such, when some peerless mighty figures wanted to refine their mobile enchanted treasures, they would have to hire the mighty figures, who knew spatial dimension laws, at high prices to open an independent space for them in the enchanted treasure.

Mighty figures, who had the ability to open up independent spaces in items, led an extremely comfortable life even in the 12 Empyrean Heavens.

Now, Yi Yun had only grasped Void Tearing, but to even tear the thick spatial barrier in front of his eyes apart was extremely difficult.

Yi Yun took his pure Yang broken sword out of his interspatial ring. He imbued spatial dimension laws into the pure Yang broken sword and he slashed at the spatial curtain!

“Cha!”

The blade tore through the void, as the spatial barrier cracked. However, after the crack appeared, it began to fade away at a speed visible to the naked eye. Spatial barriers had the ability to restore themselves.

Yi Yun had to tear it apart before the spatial barrier fully restored, but this was easier said than done.

By just slashing about a dozen strikes with his sword, Yi Yun already felt the energy deficit in his body, and he felt faint.

“Oh?”

Yi Yun frowned slightly. He knew that this was due to the impure energies in his body.

In this alternate dimension, Heaven Earth Yuan Qi had been isolated. So for all this time, Yi Yun and Lin Xintong would rely on the energies supplied to them through desolate bone relics, be it for their body consumption, healing or nomological meditation.

The more desolate bone relics they ate, the more impure the energies in their bodies were. This was inevitable.

After taking a deep breath, Yi Yun calmed himself again. Ever since he entered the Yuan Opening realm, the battles he went through and the insights he gained over the years, as well as the arduous cultivation in this alternate dimension, Yi Yun had long consolidated his realm. He could now greatly improve his cultivation level.

As long as he broke through the spatial barrier, he would be able to absorb Heaven Earth Yuan Qi and make a breakthrough immediately.

But now, the spatial barrier had yet to be torn apart!

Yi Yun was in no hurry. He meditated quietly in front of the spatial barrier, while the Dao Leaf floated in front of him. The leaf veins shimmered with a golden glow.

“Open!”

Yi Yun roared as he slashed out with the pure Yang broken sword!

“Chi!”

The spatial dimension forces were severed by the pure Yang broken sword, as a large spatial rift a hundred foot long appeared in front of Yi Yun.

“It’s opening!”

Lin Xintong’s eyes lit up. Just producing a few more of such spatial rifts would cause the spatial barrier to collapse, however, at that moment…

With a crisp but nearly imperceptible chipping sound, an inconspicuous black charm seal shattered along with the spatial rift’s appearance, transforming into strands of black gas.

This black charm seal was embedded in the chaotic spatial dimensional forces, so it was difficult to detect it. So even though Yi Yun had some knowledge of spatial dimension laws, he could tell that something was amiss with this charm seal!

Yi Yun shuddered for a moment as he slowly lowered his broken sword.

“What’s wrong?” Lin Xintong asked.

“I seem… to have triggered the Black-armored Demon God’s trap, or it might be some form of alert mechanism.”

“Oh?” Lin Xintong was astounded. “Isn’t the Black-armored Demon God asleep? He can still wake up with the alert mechanism?”

Yi Yun shook his head. “It’s impossible that he can wake up as he pleases. If not, the Black-armored Demon God’s slumber would be like child’s play. The moment he enters deep slumber, he definitely cannot be awoken easily. If that happens, his soul might collapse immediately. Besides, I still have the evil energy left inside his soul sea!”

Yi Yun’s gaze was cold as he forcefully gathered Yuan Qi, slashing out again with the pure Yang broken sword!

In the alternate dimension, Heaven Earth Yuan Qi was isolated, so Yi Yun’s stamina was being quickly depleted. He lacked the energy required to tear apart the surrounding space.

“I’ll help you!”

Lin Xintong held onto Yi Yun’s hands, as a continuous stream of pure Yin Yuan Qi surged into Yi Yun’s body.

The two of them cultivated the ’Great Empress Heart Sutra’, so despite them not having much Yuan Qi left, and were relying on the impure Yuan Qi from desolate bone relics to sustain themselves, the Jade Marrow Spiritual Energy and Nine Yang Spiritual Energy that was in its truest Origins remained intact. This was the foundation of the ’Great Empress Heart Sutra’.

Lin Xintong and Yi Yun held hands as the Jade Marrow Spiritual Energy and Nine Yang Spiritual Energy slowly blended together. Yi Yun felt a refreshing feeling flowing into his body, like his nearly dried up meridians were being revived.

Another slash!

Yi Yun roared as all his body’s energy surged out without reservation.

Chi La!

The thick spatial barrier was split apart by Yi Yun’s strike. Following that, the spatial dimension forces sealed in the spatial barrier surged out like a storm. Even the spatial maze and array formation seals set up by the Black-armored Demon God were completely shattered!

Yi Yun’s muscles ruptured as the strike he just dealt was something his body could not withstand.

It was open!

Yi Yun and Lin Xintong were delighted. Yi Yun’s strike had opened up a spatial passage, and after the spatial storm dissipated, what welcomed Yi Yun and Lin Xintong was an independent space!

This space was filled with a thick, evil aura. It belonged to the Black-armored Demon God!

Yi Yun focused his eyes as a stalwart man, dressed in torn armor, was floating in the void. His arms were around his chest, and his eyes were shut. He was deep in sleep.

This was the Black-armored Demon God!

“It’s him! Black-armored Demon God!”

Lin Xintong’s pupils constricted and the frost Qi in her sword surged. The Black-armored Demon God was indeed deep in slumber, and even though they had torn the spatial barrier apart, he remained asleep.

Maybe he knew what was going on, but he could not wake up immediately.

Take advantage of his perilous situation!

Yi Yun had charged at the Black-armored Demon God, and at the same time, the Draco First True Gold avatar in his dantian flew out. It wore a pale gold robe, and 999 flying sabers revolved around it. Thousand Snow Domain!

Yi Yun’s actual body flicked his hands, as the Death Soulwood began to spin in front of his body. The Withering domain immediately caused the murderous aura in this space to wither and die out due to the Death Soulwood.

“Die!”

Yi Yun shouted. Just as Lin Xintong thought he was about to kill the sleeping Black-armored Demon God, Yi Yun and the Draco First True Gold avatar flew past the Black-armored Demon God’s body.

“Oh?”

Lin Xintong was startled. But in a blink of an eye, Yi Yun and the Draco First True Gold avatar had flown a thousand feet away from the sleeping Black-armored Demon God. Here, the Thousand Snow Domain’s 999 flying sabers condensed into one, slashing into emptiness with Withering Sword Intent!
