The Northern Song Dynasty returned south, seeking the truth of the Dao.

Wang Zhenhuan's feet were already embedded in the ground, and it was too late for him to dodge. So he crouched down, gathering all his spiritual energy in his hands. He then threw a punch at the attacking demon.

Attacking where the enemy must defend is indeed a very effective tactic in most situations. As the saying goes, the best defense is a good offense, and that's exactly what Wang Huanzhen was thinking at that moment.

However, he overlooked one crucial point: the immense disparity in strength between the two. Seeing Wang Zhen's fist aimed at him, the demon not only didn't dodge but instead smiled contemptuously.

A palm struck Wang Zhenhuan directly in the chest, while Wang Zhenhuan's fist slammed into the monster's head. But to his surprise, his fist passed right through the monster's body.

It was as if the monster's head didn't exist. Wang Zhenhuan's punch missed its mark, and he staggered. Then, he was sent flying by the monster's palm strike.

Ling Zhizi also came to her senses at this moment. She flicked her left hand forward, sending the ribbon in her hand flying. The ribbon, which glowed with light, looked soft and weak, but when it hit the demon's arm, it produced a sound like metal clashing.

The demon let out a miserable cry, quickly withdrew its hand, and then disappeared again. Seeing this, Ling Zhizi hurriedly helped Wang Huanzhen, who was lying on the ground, up, while constantly looking around.

Wang Zhenhuan already had a chest injury, and he had previously taken a kick from this powerful demon. This time it was even worse than before; he even felt that he had very few ribs left in his chest.

He was also having difficulty breathing, and after spitting out a mouthful of blood, he gasped for air, his mouth agape, on the verge of death. He supported Ling Zhizi with one hand.

His other hand rummaged in his pocket for a long time before finally pulling out a porcelain bottle with trembling hands. His eyes were already starting to cloud due to lack of oxygen. His trembling hands couldn't hold the bottle properly.

Seeing this, Ling Zhizi grasped the red cloth on the lid of the porcelain bottle with her left hand, and Wang Huanzhen pulled hard. After finally opening the porcelain bottle, he put it to his lips without hesitation.

He swallowed both pills from the bottle. After swallowing them, he immediately felt a surge of energy. His dantian felt warm and comfortable, and his breathing became easier.

Two breaths later, he no longer needed Ling Zhizi's support, and his complexion began to regain its rosy hue. His cultivation level broke through from Seeking Truth to Deep Crimson Bright Truth. Three breaths later, he had fully recovered.

His cultivation level broke through again, soaring straight to the deep red Mingzhen realm. His spiritual energy instantly filled his body, bringing him to within a step of the light blue Zhixuan realm. Ling Zhizi was right beside him.

She witnessed all of this and stared at Wang Zhenhuan in disbelief. She couldn't understand what kind of elixir could have such astonishing effects. Wang Zhenhuan offered no explanation.

He stepped forward and stood before Ling Zhizi. Looking at the open space not far away, he said in a cold voice, "You should rest well. Leave the rest to me. Whether it's life or death, we must fight."

There was no time to allow him to slowly experience the changes brought about by his improved cultivation. The biggest change he noticed was in his eyes. Xuan Yangzi had previously mentioned that his eyes were unusual.

He can now see things that ordinary people cannot. The biggest change after his cultivation level improved is that the hidden great demon has now come into Wang Zhenhuan's view. This is also the reason for his confidence.

Although the difference in cultivation level still exists, as long as one can see, it's not without the power to fight. Moreover, he has already prepared for the worst. The Zhou Tian Secret Manual records a magical technique.

It is called "Yin Yang Borrowing Technique." It is an ancient forbidden art. As the name suggests, it involves overdrawing one's own lifespan to gain an increase in cultivation level. This increase is irreversible.

In other words, although one's cultivation level can surge after using it, one's lifespan is practically over once the spell ends. Because this technique was too domineering, it was later improved by the ancestors of the Taiqing lineage.

In exchange for slightly sacrificing the spell's effectiveness, one can end the spell earlier. In other words, one can control how much lifespan is lost to mitigate the negative effects.

Wang Zhenhuan pondered for a long time; this was the only way he could think of to break the deadlock. He was now only one step away from achieving the Blue Qi. Although he didn't know exactly how much the "Borrowing the Universe Technique" would elevate him.

However, as long as he can reduce the gap in cultivation level with this demon, the situation won't be one-sided. Only by engaging this demon in a prolonged battle can he be confident of finding an opening and using it to defeat the enemy.

The demonic creature clearly noticed the changes in Wang Zhenhuan. However, seeing that he hadn't broken through to the Blue Qi realm, it didn't take it seriously. It then focused on Wang Zhenhuan's breakthrough and recovery.

It simply stopped hiding and waved its hand, dispelling its concealment technique. Standing not far away, it looked at Wang Huanzhen with a half-smile and said, "Kid, the pills are quite effective, but how many do you have?"

What use is an elixir of immortality in the face of absolute power? Humans are like that, with a lifespan of only a hundred years, yet they love to indulge in delusions, dreaming of becoming immortals. That celestial realm.

How dare you, a lowly mortal, lay your hands on it? All mortals who dream of becoming immortals deserve to die! Since you still harbor illusions, I will crush all your hopes!

"I won't hold back now! Kid, enjoy this last bit of fun!" The monster grinned menacingly, then vanished again.

"Then let's wait and see," Wang Zhenhuan said coldly, his face expressionless. He pretended not to see the demon's form and began to form hand seals.

The demon was indeed arrogant. Seeing that Wang Zhenhuan was about to make a move, it didn't act at all. Instead, it stood still, watching Wang Zhenhuan make hand gestures, and even copied a few of the gestures with its own hands.

Wang Huanzhen was delighted to see his arrogance. He immediately quickened his pace and began silently reciting incantations. Although the Qiankun Borrowing Technique had been modified by the Taiqing Ancestor...

However, it remains a forbidden technique, and its casting method differs from ordinary spells. Ordinary spells only require a single hand seal, while Yin-Yang Borrowing Technique requires both hands. It also necessitates the use of incantations.

"The Supreme Stars respond without ceasing, expelling evil and binding demons to protect the body and preserve life. Wisdom is clear and the mind is calm and the spirit is serene; Yin and Yang borrow the law, the Great Dao is merciless! The Primordial Emperor, the Great Dao Lord, hasten as the law commands!"

As Wang Zhenzhen finished chanting the true words, a sudden sensation arose around him. The pure yang energy of the Nine Heavens and the pure yin energy of the Nine Netherworlds entered his body through the Baihui point on the top of his head and the Yongquan point on the soles of his feet, respectively, flowing along the meridians directly to the Ren and Du points.

After circulating through the body's energy channels, the dragon and tiger converge in the dantian. Yin and Yang unite, transforming into pure spiritual energy. Wang Zhenhuan's spiritual energy surged instantly, and in contrast, his hair began to gradually fade.

Three breaths later, Wang Zhenhuan had already broken through two realms, reaching the Blue Qi Ascending Profound realm. This explosive growth gradually slowed down. After five breaths, his realm stabilized at the peak of the Blue Qi Ascending Profound realm.

He was only a step away from that deep blue, lofty realm. Wang Zhenhuan opened his eyes, a flash of brilliance passing through them.

Although his face remained unchanged, his once black hair had turned completely white...
