Pale gold immortal spiritual energy from in between Ling Yun's brows and warm golden dragon spiritual energy rushed into his energy center simultaneously!
"What the hell? What is this?!" Ling Yun was filled with joy. It was a stark difference from a moment ago when his hopes had been dashed.
Even though he was a peerless genius in the Cultivation World, what was happening right now was unheard of!
The pale golden immortal spiritual energy and warm golden dragon spiritual energy immediately supported the white immortal spiritual energy in its counterattack!
It slowly made its way, engulfing the energy center before it stopped at roughly the midpoint.
The dragon spiritual energy and immortal spiritual energy merged into one and became a light source with the silhouette of a dragon. It then planted itself firmly in the middle Ling Yun's energy center and isolated the black and white immortal spiritual energy!
All signs of pressure and uncertainty were swept away. They were replaced with flashes of excitement in Ling Yun's eyes! He took the opportunity to focus on cultivating the Yin-Yang harmony balance!
Dark Yin Qi continuously rushed into Ling Yun's energy center. However, both the black and white immortal spiritual energy were shrinking rapidly after being cut off from their food source!
They became two small dots like small stars in the night sky. They spun around the light source with the silhouette of a dragon.
It started channeling immortal spiritual energy instead of dragon spiritual energy into Ling Yun!
The immortal spiritual energy didn't travel by the twelve principal meridians this time. Instead, it went through the governor meridian, also known as the yang meridian, straight into Ling Yun's energy center. That forced out the remaining Dark Yin Qi and occupied half of Ling Yun's energy center!
The Dark Yin Qi came to the side of the white immortal spiritual energy, seemingly afraid of overstepping its boundaries.
The was how the immortal spiritual energy from the Emperor Brush surrounded that black dot and the Dark Yin Qi surrounded the white dot!
The Yin embraced the Yang, and vice versa!
This time, the dragon spiritual energy and immortal spiritual energy from the Emperor Brush were absorbed pretty fast. It stopped once the energy center was full.
Ling Yun began to absorb the Dark Yin Qi with the protection of the dragon silhouette. He finally entered the last stage in the cultivation of the Yin-Yang harmony balance.
Ling Yun was now able to control the flow of the Dark Yin Qi. He channeled it through the conception meridian, also known as the yin meridian, into his energy center.
Ling Yun silently practiced the Yin-Yang harmony balance to transform the immortal spiritual energy in his energy center into Pure Yang Qi while absorbing the Dark Yin Qi at the same time.
Everything was going well. His heart was now at ease.
After some time, Ling Yun finally transformed all the immortal spiritual energy in his energy center into Pure Yang Qi. He managed to control the process well, resulting in a perfect balance between the Dark Yin Qi and Pure Yang Qi.
Ling Yun calmly cultivated, waiting only for the moment of mastery.
It started with a bang. Ling Yun felt the Pure Yang Qi and Dark Yin Qi in his energy center moving simultaneously, like a pair of white and black fishes chasing each other's tails.
Ling Yun's energy center became a Tai Chi Diagram that spun ferociously. It circulated the Yin and Yang Qi into his Twelve Principal Meridians and Eight Extraordinary Meridians.
I've mastered the Yin-Yang harmony balance!
Ling Yun broke through to Physique Tempering Stage Four at almost the same time and felt an instant surge of power.
Ling Yun's face broke into a lighthearted smile. He slowly opened his eyes, radiating with newfound confidence!
Ling Yun's energy center and meridians had expanded more than twenty times its size through this arduous cultivation.
Ling Yun's energy center was now the size of a ping pong ball. The black and white immortal spiritual energy did not disappear but instead became sesame-sized spots.
Ling Yun could feel the magical transformation of his energy center even though he could not see it. It had become a lot stronger as well.
"Yin begets Yang and Yang begets Yin when pushed to the limit. They can be transformed freely in the energy center while maintaining balance… This is the true Yin-Yang harmony balance!" Ling Yun muttered to himself. He massaged his numb legs on the floor.
It was the perfect breakthrough that he hadn't expected!
Ling Yun had been so immersed in cultivation that he hadn't noticed the passage of time.
He took out his mobile phone from the spatial ring to check the time, only to find that the battery had died. He could only smile bitterly as he got up.
Ling Yun loosened his stiff body gently and cracked his joints. It almost made him cry out in comfort.
I've to get something to eat first… Ling Yun noticed an intense growl from his stomach.
He glanced into the distance and found Little White shivering in cold. His heart winced apologetically and jumped over immediately.
"Have you been protecting me all these while? You must be freezing."
Little White had not moved an inch since Ling Yun had started his cultivation.
She had been fighting hard against the cold since her level was inadequate.
Ling Yun scooped Little White into his arms and set several Fire Talismans ablaze to warm the area up.
Little White stayed motionless in Ling Yun's tight embrace. She looked docile and cute.
Ling Yun lightly patted Little White's body. "Let's leave this place for some food," Ling Yun said to Little White when she regained some warmth in her body.
He used the Thousand Miles Godly Steps to head straight into the cave he had come from.
At Physique Tempering Stage Four, Ling Yun could now generate spiritual energy internally. That meant that spiritual energy was no longer a constraint.
He could do whatever he desired now!
Ling Yun's vision had also improved several times. He could see everything fifty meters away with only the light from the luminescent pearl in his front pocket.
He would definitely be able to see thirty meters into the darkness even without the luminescent pearl.
With the Dragon Scale Knife in his left hand and Little White in his right, he traveled northwards in the cave for about ten minutes. He passed through a large cave that ran east to west and finally entered the Yang Formation.
The temperature shot up to more than thirty degrees Celsius in the Yang Formation. Ling Yun sized up the dry cave wall before settling down for their meal.
Ling Yun and Little White wolfed down everything Ling Yun had prepared in the spatial ring.
"Let's see if there are any treasures here. If there aren't, we'll retrieve the sputum of the dragon!"
Ling Yun and Little White were actually directly underneath the valley in between Nancui Peak and Dragon Mountain. The cave that ran in the east-west direction was just below the underground dark river. If they had gone eastwards, they would have found the place where Longxian Grass grew.
That would also be the center of the Yin-Yang Dragon Lock Spell!
Little White nodded happily at Ling Yun after returning to normal.
After attaining Physique Tempering Stage Four, Ling Yun had become free from his greatest constraint — spiritual energy. He enjoyed the feeling of being free and happy.
Ling Yun used his Thousand Miles Godly Steps to its maximum and found to his delight that he could travel at double his initial speed!
Hehe, awesome!
Ling Yun stabilized the breakthrough as much as he could. He ran at full speed and absorbed the Yang Qi with his Yin-Yang harmony balance.
"Little White, have you been here before?" Ling Yun asked.
Little White shook her head in response. That brought Ling Yun some relief because it would be difficult for others to get here if even Little White had not been able to.
They were still more than a hundred meters below the underground river. Even though the terrain differed, they were definitely nearing the center of the Yin-Yang Dragon Lock Spell.
Ling Yun could find it so easily because he was an expert at spell formations.
Ling Yun knew that he was on the right track because the temperature had already risen to more than forty degrees Celsius.
There must be lava underneath the Yang Formation! Ling Yun thought glumly as he slowed down and proceeded with caution.
