I have changed my destiny and become an unparalleled immortal.

Half a day later, Gu Yun was found, but he could only watch from a distance and could not get close, otherwise it would be dangerous.

The sky was covered with dense, ominous clouds, and thick bolts of purple lightning kept striking down.

In the center of the swamp, a golden, mountain-sized, heaven-devouring toad roared in despair.

Less than a hundred feet from the demon toad, a girl of thirteen or fourteen years old slumped on the ground in the mud.

She was covered in blood, clutching a low-grade spiritual herb covered in mud tightly in her arms.

Her name was Su Wanyin, a mortal who hadn't even reached the first level of Qi Refining.

In order to gather medicine for her seriously ill younger brother, she ventured into the outer edge of Sunset Swamp, but unfortunately got caught up in the tribulation of this great demon.

"Am I going to die here...?"

Su Wanyin looked at the lightning bolt that was striking her from above due to the struggling toad, and closed her eyes in despair.

Just as the tribulation lightning was about to strike!

"Whoosh!"

A burly man with a bare upper body, dark bronze muscles, and a full head of silver hair.

He didn't even use his magic power, but blocked the tribulation lightning with his own body.

With a "bang," the tribulation lightning, powerful enough to kill a Foundation Establishment cultivator, scattered in all directions as lightning.

Su Wanyin opened her eyes blankly, staring at the tall figure blocking her way, momentarily forgetting to breathe.

"Young lady, this is not a place for you."

Gu Yun glanced back at her and saw that she was thin and bony, yet she was desperately protecting a low-quality spiritual herb. His eyes were touched.

That was the look in his eyes that he used to know, the look of someone struggling to survive at the bottom of society.

Gu Yun ignored her and turned to look at the Devouring Toad, which was already on the verge of death after being struck by the Heavenly Tribulation, his eyes shining.

"Such pure spiritual energy! Such fragrant flesh and blood! I'll accept it!"

Gu Yun unleashed the power of his Great Wilderness Body, slamming his body heavily onto the back of the demon toad!

"Glug! Glug!"

The devouring power of the Thirteen Pearls of the Purple Mansion was fully activated, and a massive amount of spiritual energy turned into a torrent, surging into Gu Yun's body!

"Buzz!"

Inside Gu Yunzi Mansion, the string of beads representing taste and desire began to spin wildly and crystallize under the nourishment of this enormous energy!

boom!

With a muffled sound from within his body, the Desire Pearl underwent a complete transformation, turning into a substantial Dao Foundation that exuded a strange fragrance and flowed with the Dao of Devouring!

The eleventh foundation of the Dao is complete!

"belch"

Gu Yun jumped out of the shriveled toad corpse.

He turned around to find a place to wait for his stay to end, but found that the girl named Su Wanyin was still sitting in the mud, looking up at him with an almost worshipful gaze.

Gu Yun casually gathered a wisp of essence blood, which turned into two blood clots.

"Clatter".

Gu Yun was thrown into Su Wanyin's arms.

"Eat it. It can save your brother and also cleanse your marrow and bones."

Gu Yun looked at her, his voice calm, "I saw the will to survive in your eyes; it's just that you're destined to be with me."

Su Wanyin trembled all over, cupped her hands, and kowtowed to Gu Yun in the muddy water.

"Thank you so much for saving my life and bestowing this treasure upon me, Senior! I am Su Wanyin... May I ask your honorable name? If I am fortunate enough to embark on the path of immortality, I will surely repay your kindness!"

"repay?"

Gu Yun's body began to turn transparent at the edges. He threw his head back and laughed, his voice echoing beneath the clouds of tribulation:

"I'm just a passerby. If you truly have this heart, then live on with all your might. Once you cultivate to the Golden Core stage and have the ability to not be trampled underfoot, perhaps... we'll meet again someday."

As soon as he finished speaking, with a "whoosh," Gu Yun's figure turned into specks of red light and disappeared completely in Su Wanyin's shocked gaze.

"...Golden Core..."

Thirteen-year-old Su Wan forever etched that silver-haired, dark bronze figure into the depths of her memory.

...

"Whoosh!"

The dizziness from the passage of time and space disappeared.

Gu Yun checked himself and found that the Red Butterfly Mark in the Book of Destiny was very stable, indicating that although his actions had changed the fate of a young girl, they had not triggered the vicious paradox of causing him to disappear.

Gu Yun looked at the blood-red butterfly mark with his divine sense and couldn't help but gasp.

[Subject: Gu Yun]

Current lifespan: 385

He was mentally prepared to rewind 31 years of his lifespan and deduct 31 years. But the extra 10 years of lifespan that evaporated caused him a pang of heartache.

Another line of text appeared, which disappeared automatically after Gu Yun finished reading it.

Smuggling oneself through time and space violates the laws of nature. The first day of such a stay requires 10 years of one's lifespan to conceal the secrets of heaven; the second day requires 20 years; the third day requires 40 years... and so on, doubling in number!

"In other words, with my current lifespan of less than four hundred years, if I dared to stay in the past for six days, I would be instantly turned into a dried-up corpse by the laws of Heaven?"

Gu Yun wiped the cold sweat from his forehead.

"This ability to reverse time is truly like dancing on a knife's edge."

"I wonder what cultivation level that little girl has reached after thirty-one years. I wonder if she could be my Golden Core stage assistant in the Cangbei Spiritual Domain?"

Gu Yun smiled, in a good mood.

He didn't linger any longer, urging his qi and blood to rush back to the Supreme Heartless Peak of the Cold Moon Palace under the cover of night.

Early in the morning, Gu Yun had just changed out of his mud-stained clothes and was preparing to go to the bedroom to see if Mo Qianyan had woken up.

Just then!

"BOOM!!!"

A loud bang came from the direction of the spiritual spring behind the Heartless Peak, followed by panicked screams.

"Father! Mother! Something terrible has happened! The black egg has cracked!"

Gu Chengfeng's rough voice changed tone due to panic.

Gu Yun raised an eyebrow and dashed away in a flash. At the same time, a sword light descended from mid-air, and Mo Qianyan appeared solemnly by the spirit spring.

Both of them looked at the center of the spiritual spring at the same time.

The dark gold egg that had been with Gu Chengfeng for eighteen years and that he had brought back was now shattered into countless eggshells.

What hatched from the egg was not some ancient ferocious beast, but a creature with yellowish-brown downy fur, drooping ears, and a constantly wagging tail. It was round and plump, like a small ball of dirt, and had no trace of majesty.

At this moment, this "little earthen ball" is holding a piece of ten-thousand-year-old black iron essence that Gu Chengfeng used to refine his body.

They were munching on it with a "crunch crunch" sound, like they were eating a radish.

"What...what is this? A dog?"

Gu Yun's eye twitched.

"Dad! It not only gnaws on iron, but it also pulled up the three-hundred-year-old Snow Jade Ginseng from the medicinal herb field! It eats everything!"

Gu Chengfeng was about to cry.

The little yellow dog seemed to hear the noise and stopped eating.

It turned around and glanced at the crowd with a rather disdainful look.

But the next second, its wet nose suddenly twitched violently.

"Sniff...sniff..."

The little yellow dog's gaze passed over Gu Chengfeng and locked onto Gu Yun!

To be more precise, it was the scent of Gu Yun's Dao foundation that they detected!

For this young beast, which is born with the instinct to devour, it is a walking, human-shaped delicacy.

"Woof!"

The little yellow dog barked excitedly, kicked off with its four short legs, transformed into a streak of yellow lightning, opened its big mouth, and bit directly at Gu Yun's stomach!

"You little brat, I just finished eating over there, and now you want to eat me?"

Gu Yun almost laughed.

He didn't move, but simply reached out and accurately pinched the puppy by the scruff of its neck, lifting it up.

"Woof! Woof!"

The little yellow dog kicked its limbs wildly in the air and opened its mouth to bite Gu Yun's dark bronze wrist.

"Ding!"

With a sharp crack, the little yellow dog covered its mouth, tears welling in its eyes, as its baby tooth was almost broken.

"All you ever do is eat, eat, eat. I might as well call you a glutton."

Gu Yun chuckled and flicked its forehead.

Looking at the little yellow dog struggling in Gu Yun's hands, Mo Qianyan rubbed her forehead in exasperation.

"This black egg hatched into such a gluttonous dog? I'm afraid there won't be any peace in the Cold Moon Palace from now on."

"What's there to be afraid of? We have our son."

Gu Yun waved his hand and tossed the little yellow dog into Gu Chengfeng's arms.

"Feng'er, this little yellow dog is yours to take care of from now on. Whatever it wants to eat, go up the back mountain and catch it for it. It's a good opportunity to practice your agility."

Holding a yellow dog that was frantically tearing at his clothes, Gu Chengfeng looked grief-stricken.

"Dad! I'm your own son! This isn't raising a pet, it's like you've found me a patriarch!"

"Stop talking nonsense. If you don't take good care of it, you won't get any food today."

Gu Yun put his arm around Mo Qianyan's waist, ignoring his son's wails, and walked towards the bedroom with a smile.
