Qiu Zu: From an apprentice in a medicine shop to an immortal ancestor.

Good heavens, this old man wasn't lying; he really had the goods!

With the verification of the [Miro Palace], Qiu Zhen recognized the ordinary, yellowed book as something extraordinary at a glance.

There really was an incredible immortal opportunity inside.

Qiu Zhen was overjoyed and wanted to delve into it with his spiritual sense to investigate, but at that moment, he heard Bai Shu's call in his mind.

"That burly man is trying to escape!"

Qiu Zhen's heart stirred.

Earlier, he saw Bai Shu gaining the upper hand in the fight against the middle-aged man, so he didn't pay much attention and focused on dealing with the old man "Yuan Hua" who was secretly casting spells, capturing the leader first.

With the death of the old man "Yuan Hua," the middle-aged man probably sensed something, panicked, and thought of fleeing.

"I can't let him get away."

Qiu Zhen stuffed the book into his chest and immediately left the cave.

As soon as he left the cave, Qiu Zhen's Heavenly Eye displayed its power, looking into the distance.

Bai Shu, like a bolt of lightning, with ghostly movements, was constantly chasing and engaging in close combat. The middle-aged man's body was covered in terrifying wounds, with blood seeping out.

Clearly, in the previous fight, the middle-aged man was no match for Bai Shu, who possessed the bloodline of the [Wind and Thunder Spirit Fox].

However, his physical body seemed extremely strong.

Under Bai Shu's wind and thunder claws, which could split rocks and break iron, he only suffered minor injuries.

The external injuries looked severe, but they were just superficial wounds that didn't damage his muscles or bones, and he hadn't lost his fighting ability.

"What a powerful physical body."

Qiu Zhen was slightly surprised.

The [Divine Demon Five Animal Mimicry] martial art he practiced from the Medicine King Valley was considered an extremely powerful superior martial art, and it was definitely a first-class foundation-building technique in the martial world.

However, even if [Divine Demon Five Animal Mimicry] was mastered, without protection, directly facing Bai Shu's wind and thunder claws would definitely cause damage to the bones and muscles, rather than just superficial wounds.

But this guy...

"He's got something."

Qiu Zhen thought of that "Immortal Martial Art" and couldn't help but feel anticipation.

However, he didn't think too much about it, took the iron-tire heavy bow from his back, drew the bow, nocked an arrow, empowered it with a Golden Light Thunder Talisman, and calculated with his primordial spirit Dharmakaya...

"Whoosh!"

A golden lightning bolt shot through the air.

Bai Shu and Qiu Zhen had a telepathic connection. Knowing that his young master was about to attack, it opened its mouth and spat.

A demonic wind blew, enveloping the middle-aged man, confusing his senses.

Martial artists with strong Qi and blood were naturally able to break the demonic wind illusions of demons, so Bai Shu had been unable to subdue him until now.

However, breaking the illusion took time.

The middle-aged man stirred his Qi and blood to break the demonic wind, and as soon as he emerged, a golden arrow entwined with lightning flew over.

"No!"

Tie Zhu was shocked, his eyes bloodshot, wanting to dodge, but at this moment, the arrow was in front of him, and he had no room to maneuver.

"Bang!"

With a force of a thousand pounds, the arrow pierced his chest.

Under the impact of the tremendous force, the burly man was shot to the ground.

Upon seeing this, Bai Shu pounced on him without saying a word, biting the burly man's neck, completely ending his life.

"Bai Shu is quite fierce."

Qiu Zhen watched the battle from afar and was very satisfied with Bai Shu's performance.

In terms of martial arts combat alone, without the empowerment and calculation of his primordial spirit Dharmakaya, he was probably no match for Bai Shu at all.

Annihilating the last enemy, he breathed a slight sigh of relief, then remembered something and turned his gaze to a spot not far from the cave entrance.

In the mud at the cave entrance, a palm-sized brown wooden figure lay quietly.

The wooden figure was charred, with faint tree branch-like burn marks.

"It withstood two of my [Golden Light Thunder Talismans], and the wood spirit hasn't died yet."

Qiu Zhen was slightly surprised and pleasantly surprised.

Another treasure.

He stuck a thunder talisman on the small wooden figure and casually collected it.

After dealing with these matters, Qiu Zhen didn't delay, quickly destroying the altar arranged in the cave, and cremating the bodies of the old man and the middle-aged martial artist with thunderfire...

Those who often kill people know that killing is not difficult; what is difficult is cleaning up the aftermath.

Qiu Zhen's primordial spirit Dharmakaya deduced and cleaned up the "crime scene" very carefully, making sure not to leave any clues about himself.

Half an hour later, on a mountain path.

"Young master, that burly man's bones were really tough."

Bai Shu lay on Qiu Zhen's shoulder, touching its head, feeling a little embarrassed.

The other party wasn't wearing any armor, just simple linen clothes, but relying on his physical body, he endured several of its claws and only suffered superficial wounds, which made it doubt its existence.

It had awakened the power of the innate demon beast bloodline, empowered by wind and thunder, and its strength was much stronger than ordinary acquired demon beasts.

In the acquired realm, it could definitely walk sideways.

But the result...

"It's not your problem; his bones are indeed tough."

Qiu Zhen agreed.

The old man Yuan Hua quickly turned to ashes under the burning of thunderfire, but the burly man named Tie Zhu burned for a long time.

His bones faintly shone with a faint golden light.

"There must be a reason for this."

Qiu Zhen's mind moved, thinking of the "Immortal Martial Art" mentioned by the two, and he took out the ancient, yellowed book from his chest.

He flipped through it, his mind sinking into it.

In an instant, golden light surged into his mind.

Immediately afterward, the scene of an immortal practicing martial arts appeared in the depths of his heart.

"This is... immortal charm."

Qiu Zhen was overjoyed; there really was an immortal martial art.

Immediately, without saying a word, he found a secluded place, let Bai Shu protect him, and meditated to comprehend it.

About a quarter of an hour later.

"Lu Zu's Strengthening Tendons and Bones Skill..."

Qiu Zhen muttered to himself, his heart filled with surprise.

Strengthening Tendons and Bones Skill—the name of the martial art couldn't be more ordinary.

Even a village martial arts hall wouldn't give its martial art such an ordinary name.

However, the prefix of the technique was the name "Lu Zu."

After Qiu Zhen's enlightenment, he was surprised to find that the immortals and Buddhas he knew in his previous life, such as Guanyin Bodhisattva, the Great Sun Tathagata, the Three Purities, etc., all had similar legends in this world, no different from his previous life.

Lu Zu, Lü Dongbin's name, resounded throughout the cultivation world.

"It's actually Lu Zu's martial arts inheritance; no wonder..."

Qiu Zhen understood.

No wonder that middle-aged man's muscles and bones were so strong; it turned out he had practiced Lu Zu's martial art.

Compared to the mysterious and profound immortal techniques and Taoist arts, which were difficult to master, martial arts cultivation seemed much more straightforward, and with the blessing of immortal charm, it was much easier to comprehend.

That middle-aged man had learned a few of its essences, let alone Qiu Zhen, who possessed the primordial spirit Dharmakaya.

After some comprehension, Qiu Zhen had some understanding.

《Lu Zu's Strengthening Tendons and Bones Skill》 is a martial art that cultivates the lower dantian, nourishing the five internal organs internally and nourishing the tendons, bones, skin, and hair externally. Like the [Divine Demon Five Animal Mimicry], it belongs to the acquired foundation-building level of martial arts.

However, although both are "acquired foundation-building" martial arts, 《Lu Zu's Strengthening Tendons and Bones Skill》 is a true immortal inheritance, with infinite creation, and it is definitely not something that [Divine Demon Five Animal Mimicry] can compare to.

This could be seen from the middle-aged man.

He must have practiced this 《Lu Zu's Strengthening Tendons and Bones Skill》 to display such amazing strength.

Bai Shu, who was protecting him, saw his young master open his eyes and was curious:

"Young master, is it really an immortal martial art?"

"It really is!"

Qiu Zhen revealed a look of joy:

"Let's go, let's go home."

With that, Qiu Zhen stuffed the yellowed, ancient book back into his chest, eager to return to "Qiu Zhen Valley."

After all, it was inconvenient outside. Only by returning to the valley could he properly comprehend and practice this 《Lu Zu's Strengthening Tendons and Bones Skill》 and see what mysterious aspects the legendary immortal martial art had.
