Immortality Begins With Internal Breathing

Dim yellow sunlight spilled down. A gentle breeze swept past, and the river surface rippled with golden waves.

In a plain courtyard by the riverbank, bursts of explosive sounds rang out continuously like muffled thunder. Lin Zheyu practiced the Great Strength Vajra Fist. With his blood qi operating at full power, a faint golden, blood-tinged aura spread outward, coating his entire body in a layer of golden radiance. He looked like a wrathful Vajra radiating Buddhist light, imposing and awe-inspiring, his momentum qi majestic and unstoppable.

The appearance of this faint layer of golden blood-tinged aura showed that Lin Zheyu had not yet achieved perfectly harmonious control over his golden blood qi. However, it was only when he drove it with full force that the golden blood-tinged aura would spread uncontrollably. Under normal circumstances, with the dual coordination of the Evernight Slumber Secret Art and the Tortoise Breath True Technique, even a Grandmaster realm expert would be unable to see through his true state.

Boom.

Every punch he threw erupted with a thunderous roar like muffled thunder. Lin Zheyu tested it for more than ten minutes before stopping in satisfaction. Such formidable attack power had definitely reached the Force Transformation realm. Weaker Force Transformation realm experts, even relying on true strength, might not be able to raise their attack speed to the point of surpassing the speed of sound.

After testing the Great Strength Vajra Fist, Lin Zheyu tried the Golden Goose Technique as well. His figure became light and ghostlike, almost impossible to see beneath the dusk sunlight. Fierce gusts of wind howled past both sides of his ears. As his speed increased, the air resistance he felt grew increasingly terrifying. The immense air resistance made him want to drive himself with full power, continuing to increase his speed and bring his bodily movement close to the speed of sound. Yet it was simply impossible. When moving his body, the air resistance he faced was far too terrifying, completely incomparable to the resistance encountered when attacking with a fist.

Huff, huff, huff~~

After a long while, Lin Zheyu came to a stop, breathing heavily.

So strong. My blood qi has become smooth and powerful, without the obscure and strange feeling from before.

Previously, the golden blood qi had been mixed with ordinary blood qi, like gasoline diluted with water, reducing the explosive power of the golden blood qi. He tested it and found that only under full explosive output was it possible to strike with a fist at a speed surpassing the speed of sound and produce a sonic boom. Even so, he was already very satisfied. An attack speed surpassing the speed of sound was something only martial artists who had reached the Force Transformation realm might possibly possess, and even then, it was only a possibility.

Weaker Force Transformation realm martial artists might not even be able to accomplish this. Yet Lin Zheyu, with only Blood Qi realm strength, already possessed such astonishing power. Once he trained martial cultivation into his bone marrow and underwent a complete transformation, his strength would become even more terrifying and powerful.

What a pity that my lightness and movement techniques have already reached their limit. Without cultivating true strength and finding a way to break through the terrifying wind resistance, it will be very difficult to further increase my speed. No, it is still possible. If I continue to improve and double my strength once or twice more, with even more terrifying power and greater explosive force, it might be possible for my body to break the sound barrier. At that time, the disturbance caused would be extremely terrifying. But doubling my strength once or twice is no easy matter, and even that might not be enough.
