To comprehend all laws and attain immortality

Generally speaking, the intelligence of a second-tier demon beast is no less than that of a mortal.

Thanks to their hunting instincts, some monsters can use lurking, disguise, and pursuit to their advantage, and they can also employ cunning and treacherous schemes.

The tree spirit, however, was not like that.

Not only are they sluggish in their movements and their coordination is completely chaotic, like puppets on strings. Apart from their tough trunks, excellent camouflage skills, and amazing regenerative abilities, they have no other innate magical abilities and rely entirely on brute force to injure people.

Gu Fan could easily draw the hatred of the second-tier tree demons to himself, preventing them from interfering with Su Nanzhi.

Second-tier demonic beasts cannot fly, so the tree demons crowded together to attack Gu Fan. The tree demons in the back row shook their branches until the tree demons in the front row were killed by Gu Fan before they could get close.

Some of the tree spirits that were set ablaze by the flames were burned to the ground before they could even get close.

Gu Fan immediately felt much less pressure!

Once again, Gu Fan used a Heavenly Sword Talisman to cut the tree demon in two, and a look of enlightenment flashed in his eyes.

"These crises were all pre-planned!"

"Golden Core cultivators entering this realm are unable to unleash their full power due to the reversal of the laws. Only by thoroughly understanding the general principles of the 'Innate Yin-Yang Transformation and Divine Evolution Chapter' can they deal with these tree demons!"

"If you can't comprehend it, but still want to obtain the subsequent techniques, you'll be dragged down and killed by the tree demon!"

While Gu Fan was slaying the tree demon, he was also observing Su Nanzhi's situation.

The key to this battle lies in whether Su Nanzhi can kill the third-tier tree demon; otherwise, even if he can hold off these second-tier tree demons, it will be of no use.

All he could do was prevent the second-tier tree spirit from interfering with Su Nanzhi.

Meanwhile, Su Nanzhi was locked in a fierce battle with the only third-tier tree demon.

The tree demon was at the early stage of the third rank, and its trunk, over ten zhang tall, blotted out the sky. Su Nanzhi was like an ant in front of the tree demon.

Su Nanzhi gritted her teeth and maneuvered her short sword swiftly, leaving a trail of golden light as it struck the branch with a bang, leaving a narrow sword mark two feet deep.

The tree spirit shook twice, making a dull sound, but soon, the wounds on the branches healed at a speed visible to the naked eye.

The resilience and regenerative ability of the third-tier tree spirit far exceeded Su Nanzhi's imagination!

Seeing this, Su Nanzhi took a deep breath, a determined look flashing in her eyes. She stopped controlling her flying sword, leaped to avoid the falling branches, and a mysterious light rose from her left hand and a golden light from her right hand. She slowly brought her hands together.

In an instant, the mysterious light and golden light intertwined and merged into a disc, which rapidly expanded in size as magical power was continuously poured in.

"Yin-Yang Grinding Mill Technique!"

When the millstone grew to a diameter of ten feet, Su Nanzhi held it up and ground it against the tree demon, as if she were holding up a dark golden sun.

The Yin-Yang millstone spun wildly, obliterating everything in its path into Yin and Yang energies, which were then absorbed by the millstone, allowing it to continue to grow.

The tree spirit's branches fell onto the Yin-Yang millstone and were instantly ground into dust, with a foul-smelling, dark green sap splattering out.

The tree demon trembled and hummed as if it had gone mad. Dozens of its branches glowed with dark green light as it lashed out at Su Nanzhi and the Yin-Yang Millstone.

Although she suppressed the tree demon, Su Nanzhi was not having an easy time either.

The magical power she used to unleash the Yin-Yang Millstone had already exceeded her limit. At this moment, her meridians were in excruciating pain, veins were bulging on her forehead, and blood was spilling from the corner of her mouth.

Using the Yin-Yang Grinding Disc Technique was a last resort, as it was the most powerful spell she possessed.

Given the tree spirit's resilience, only this technique can defeat it.

Of course, she could also retreat with Gu Fan, but that would mean giving up the cultivation techniques on the stone tablet.

Having only comprehended the general principles, she was already certain that the profoundness of the "Innate Two Elements Transformation and Divine Evolution Chapter" far surpassed her main cultivation method by more than ten times, and was definitely no less than the opportunity of obtaining the Condensing Pivot Pill.

Su Nanzhi absolutely refuses to give up!

The Yin-Yang Millstone expanded to a diameter of three zhang (approximately 10 meters) and then stopped growing; that was the limit that Su Nanzhi could control.

The tree demon's branches were crushed one after another. Its huge and clumsy body could not dodge even if it wanted to. It could only hum in despair as it watched Su Nanzhi lift the Yin-Yang Millstone and cut it in half!

Half of the tree trunk crashed to the ground, raising a cloud of dust.

The movements of the surrounding second-tier tree spirits suddenly froze, as if their thoughts had come to a standstill.

A moment later, the remaining tree spirits slowly retreated, no longer daring to take another step forward.

Seeing this, Gu Fan also stopped his pursuit.

The tree demon's trunk is tough, and it often takes two to three talismans to kill one. After one round of fighting, he had already used up nearly a hundred talismans.

"There's no way to replenish talisman paper and ink here, so we'll have to use them sparingly."

With that thought in mind, Gu Fan stepped toward the stone tablet.

But after taking only two steps, he stopped and turned to look at the fallen tree spirit's remains.

Although the tree spirit is dead, the spiritual energy in its remains hasn't dissipated. Could it be...?

Gu Fan's heart skipped a beat. He quickly stepped forward, took out his gray flying sword, and peeled off the outermost layer of bark, revealing a layer of shimmering blue bark.

"As expected, the remains of these tree spirits were made of spirit wood, and their bark was natural talisman paper!"

Turning his head, he saw a large number of tree spirits lying on the ground, many of their bark charred by flames, which made him sigh with regret.

But soon, Gu Fan's brows relaxed.

There's also a third-tier tree spirit!

Gu Fan turned and walked towards the third-tier tree demon, where he saw Su Nanzhi leaning against the fallen tree trunk, panting heavily, her forehead covered in fine sweat, and her feet in a pool of dark green, foul-smelling tree sap.

Tree sap had stained her embroidered shoes and the hem of her skirt, but Su Nanzhi did not leave. Her muscles trembled slightly, as if she could not move.

"What's wrong, fellow Daoist?"

Gu Fan quickly stepped forward and helped Su Nanzhi up. He then used his divine sense to detect that Su Nanzhi's meridians had broken. He immediately picked her up and moved her to a safe place, and then took out the Green Wood Pill and fed it to her.

A moment later, the medicinal properties dissipated.

Su Nanzhi sat up, and color finally returned to her face as she managed a smile.

"Thank you, fellow Daoist."

Gu Fan waved his hand: "It's good that you're alright, fellow Daoist."

He didn't say any nonsense about not being able to work so hard.

If you don't risk your life when faced with such an opportunity, what's the point of cultivating immortality!

Su Nanzhi nodded, then sat cross-legged, closed her eyes, and began to regulate her breathing.

Gu Fan turned around and examined the remains of the third-tier tree demon, a slow smile playing on his lips.

"The tree spirit is enormous, and there's quite a bit of usable flesh; enough to make over a dozen talismans!"

"If I can draw a dozen more third-tier spirit talismans, even without being able to use much magic power, I'll still have the ability to protect myself."

Fearing that the spiritual energy would dissipate, Gu Fan quickly peeled off the bark of the essence tree, carefully cut it into suitable small pieces, and then put it into a jade box to seal the spiritual energy.

After doing all this, he walked to the stone tablet and looked up to comprehend the Taoist inscription.

The first part of "The Innate Two Elements Transformation and Divination Chapter" contains cultivation methods from Foundation Establishment to Nascent Soul.

Gu Fan focused his mind and activated his Myriad Manifestations Dharma Eye, only to see the Daoist script twisting and merging, transforming into a strange Qi circulation diagram.

The core of the Qi Circulation Chart is the Yin-Yang cycle, which is very similar to the radiant light derived from the general principles of Daoist texts. The corresponding meridian location is the Dantian Qi Sea. From the Dantian Qi Sea outward, there are spiraling and intersecting patterns, like a large net that encompasses the five internal organs. The outermost layer consists of tiny, fine spiritual networks that extend to every corner of the body, leaving no blind spot untouched.

Judging solely from the complexity of the Qi circulation diagrams, the "Innate Two Elements Transformation and Divine Evolution Chapter" is a top-tier cultivation technique that is no less than the "Divine Firmament Langhuan Golden Book"!

What caught Gu Fan's attention was that he could vaguely see traces of new runes in the overall structure of his Qi circulation diagram.

In comparison, the two are...

The runes he had drawn earlier instantly revealed many errors.
