Qin Ming arrived at the Heaven-Devouring Rat’s closed-door training cave mansion, releasing his heart spirit for a brief sensing.

He saw that its Essence, Qi, and Spirit, the three treasures, had been nurtured to a peak state, with its profound-colored demon pill perfectly integrated, ripe and ready.

Qin Ming brewed a pot of "Dao Thunder Tribulation Tea," then channeled mana, offering it before the Heaven-Devouring Rat, urging, "This Tier Four High-Grade Spirit Tea will aid you in your transformation, deepening your comprehension of the Great Dao and backing you in overcoming several more celestial tribulations."

"Compared to using the Profound Spirit Armor to resist celestial tribulations, if you can seize this opportunity to temper your body with celestial thunder, your future potential will be even greater."

"Ultimately, the decision rests with you on how to choose and perform in the moment."

"The Transformation Celestial Tribulation is unlike any tribulation you’ve faced before, whether you leap through the gate as a dragon to become a Demon Saint or perish with your path vanished, all depends on this time."

Qin Ming didn’t forget to remind it, knowing he couldn’t be absolutely certain the Heaven-Devouring Rat would succeed in overcoming the tribulation.

The path of the Immortal Dao is endlessly long, one tribulation after another, and the tests of the Great Dao are extremely harsh; he dared not claim all could be safely passed.

Since ancient times within the Demon Race, the demon beasts that succeed in overcoming the Transformation Celestial Tribulation and advance to become Transformed Great Demons are even fewer than those of the Human Race Nascent Souls.

If it can advance successfully this time, he naturally will have a great ally at his command.

"Master, rest assured, I have more than a fifty percent chance this time."

The Heaven-Devouring Rat patted its chest, speaking with confidence brimming.

Qin Ming nodded, patting its shoulder.

It now has numerous protective measures, with him, this Nascent Soul True Monarch, watching over from outside; if it still fails to achieve the position of Demon Saint.

It would almost be a violation of the order of heaven and earth!

Even the Profound Water Crocodile and Silver-winged Frost Bee had come over, their eyes full of envy, offering encouragement to the Heaven-Devouring Rat.

"Alright, second and third brothers."

"I, the great one, must let the world see that even the street rat everyone yells to beat, will have a day to stand out!"

"No need for sentimental words, today, listen to the dragon’s roar!!"

The Heaven-Devouring Rat waved its small hand, showing a resolute expression, with movements firm and generous, emotions impassioned!

...

Three days later.

On Wangyue Island, the originally clear sky suddenly turned turbulent, becoming dark immediately.

The spiritual qi between heaven and earth swirled like a giant vortex, funnel-shaped, crazily converging towards Spirit Island.

The range of spiritual qi clouds started growing larger and larger, from initially ten li, several tens of li, hundreds of li, finally reaching a massive area of eight hundred li.

The scene was no less impressive than when the Silver Moon Celestial Fox Yue Lingyan was undergoing tribulation in the past.

After all, the Heaven-Devouring Rat had followed Qin Ming for over two hundred years, and was considered deeply ingrained.

Amidst the stirring of the winds and clouds, an astonishing demon king evil qi emanated from Wangyue Island, sweeping outward.

Along with the continuous influx of spiritual qi, the demon evil qi kept rising.

Such a mystical phenomenon of a Transformed Great Demon attempting transformation instantly attracted the surrounding cultivators.

"Look quickly! Such a powerful spiritual qi tide—there’s a demon king undergoing transformation celestial tribulation."

"It’s the direction of Wangyue Island; I heard the cultivators on Spirit Island moved out recently, never thought a Great Demon was undergoing tribulation!" 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

"It’s most likely the spirit pet under True Monarch Wangyue’s command, about to undergo the transformation tribulation."

"Indeed, indeed, I heard the old man say True Monarch Wangyue’s spirit pet is a Heaven-Devouring Rat Demon King with extremely high bloodline talent, which had repeatedly helped our Southern Wilderness."

"Time dating back to its aid during the Liang Country Tai Lake Ruins ghost disaster, defeating and killing Gold Core members of the Six Demonic Sects."

"Recently supporting Alliance Leader Wei’s Four Nations Alliance to clear the Void Anomaly, killing several powerful Golden Core demonic cultivators, yet it seldom shows its face before people."

"Truly it leaves after completing things, deeply hiding merit and fame."

"So that’s how it is, truly worthy of being the spirit pet under True Monarch Wangyue."

"The conduct style is as modest as that of the senior True Monarch..."

"If the Heaven-Devouring Rat King successfully breaks through to become a Tier Four Demon Saint, wouldn’t it mean our Southern Wilderness will give birth to another powerful combatant?"

"Next, it is highly likely to safely pass this round of Celestial Demon Tribulation!"

For a moment, the eyes of the cultivation realm all focused on Wangyue Island.

Inside the cave mansion.

The Heaven-Devouring Rat kept its eyes tightly shut, sitting cross-legged in human form, with a strange hand seal pinched in its hand, surging demonic power and evil qi from its body, its profound-colored demon pill wrapped in a layer of black halo.

Next moment.

A strange silver rune opened between its brows!
