My low-key cultivation of immortality was discovered by the emperor in my diary.

Rainbow light fell upon the pine-lined cottage.

The Aurora Fox returned to its docile and harmless appearance, lying quietly beside Chu Lengyu, a tiny little ball.

Chu Lengyu closed her eyes and concentrated, surrounded by a faint, clear light, as if she were in another world.

Seeing that its master was meditating and practicing her internal energy, the Aurora Fox dared not peek and stayed quietly in place, afraid of disturbing her.

It just didn't quite understand why, given how thin the spiritual energy was in this small world, its master didn't set up a superior spirit-gathering array or take some spiritual pills to aid in cultivation.

Could this actually be a kind of trial? A way to temper one's character through asceticism?

It secretly guessed the reason.

Silent all night.

As dawn broke, Chu Lengyu opened her eyes.

The system notification sounded on time, and today's random reward was a long-awaited increase in cultivation level.

She immediately chose to receive it.

Aurora Fox let out a soft exclamation, its eyes widening in surprise. It saw that the originally thin spiritual energy around its master had suddenly begun to gather and flow, like a river flowing into the sea, surging and turbulent.

These spiritual energies swirled and intertwined around Chu Lengyu, eventually transforming into dazzling beams of light that entered her body, making her aura even stronger.

Within Chu Lengyu's body, the spiritual energy that had been flowing slowly began to accelerate, resonating with the spiritual energy gathered from the outside world.

At that very moment, they surged forth like a flood bursting its banks, rushing towards the dantian and causing the golden core to tremble.

In the void, a purer and more powerful spiritual energy surged out, instantly filling the entire dantian.

The overflowing spiritual energy rippled around her, enveloping the entire room in a faint spiritual light.

Chu Lengyu felt a sudden lightness throughout her body, as if all the constraints had been broken at that moment, and her cultivation level also stepped up to a new stage—the mid-stage of Core Formation.

She gently raised her hand, and a gentle wave of spiritual energy spread out. The surrounding spiritual energy seemed to be summoned, and it gathered even more frantically, instantly draining all the spiritual energy in the vicinity and causing the wind and clouds to change color.

The Aurora Fox, standing to the side, felt the intense spiritual energy fluctuations that were almost tangible, and was overwhelmed with shock.

Through the soul contract, it clearly and directly sensed that its master was becoming increasingly powerful, suppressing its soul imprint completely, which was impossible to fake.

Its little head was filled with big questions, as if at this moment it had gained a completely new understanding of the world.

According to the inherited memories, human cultivators usually need to rely on spiritual treasures of heaven and earth to make good preparations when breaking through their cultivation realm, and it is a very difficult process, right?

How come its owner seems to have broken through in one go, and it seems like there are no bottlenecks at all?

The hardships and setbacks in the inheritance of memories seem insignificant in front of the master.

Could it be that the innate Dao seed is inherently so powerful?

It recalled the descriptions of rare physiques among human cultivators in its inherited memories, and its curiosity about Chu Lengyu's identity grew even stronger.

To break through realms so easily without any risk of hitting a bottleneck—such talent is probably extremely rare, even in the entire cultivation world.

Aurora Fox suddenly understood why human cultivators had risen to prominence so quickly in the inherited memories.

Even though humans are physically weak and have short lifespans, they are naturally close to the Dao and are exceptionally intelligent, which is the exact opposite of the demon race.

It also noticed a detail: the dense spiritual energy just now was generated suddenly out of thin air, resembling the legendary initiation. The master must have a powerful background! It had to cling to this powerful figure.

Thinking of this, the Aurora Fox couldn't help but feel a little smug. It seemed to have already seen its future, following Chu Lengyu, soaring through the heavens and laughing at the world of cultivation.

Aurora Fox jumped up excitedly, circling around Chu Lengyu, its eyes full of admiration and joy.

He then transmitted a message: "Congratulations, Master! Congratulations, Master!"

Seeing this, Chu Lengyu smiled and reached out to scratch its chin, as if teasing a cat.

The Aurora Fox squinted its eyes in enjoyment, but heard its master mutter with some dissatisfaction, "After forming the core, it only breaks through once every month, which is a bit slow."

Upon hearing this, the Aurora Fox abruptly stopped, nearly falling from mid-air. Its pointed ears tilted back slightly, its eyes filled with disbelief.

It quickly regained its balance, checked what it had heard again, and felt a surge of shock in its heart.

"Breaking through a small realm in a month? This... how is this possible?!" Aurora Fox exclaimed in its heart, almost doubting whether there was something wrong with its ears.

In its inherited memories, the path of cultivation for human cultivators after forming the Golden Core is extremely difficult. Each breakthrough in realm requires tremendous effort and a long period of time. How come it has become so easy for its master?

Is it possible that the times are changing too fast, and its inherited memories have become outdated?

Aurora Fox was surprised and puzzled, and couldn't help but doubt itself.

Chu Lengyu was calculating that if things continued at the current pace, she should reach the peak of the Golden Core stage around the time of the Shangsi Festival.

At that time, spring will return to the earth, and all things will revive. It will also be the time when she achieves great success in her cultivation and undergoes a transformation and rebirth.

Having completed the mission and acquired the Nine Cauldrons, she felt more composed and confident about the upcoming Nascent Soul Stage Five-Nine Thunder Tribulation.

Looking back, her recklessness during the minor lightning tribulation of 1949 still makes her feel ashamed. If she had been just a little less lucky that day, the outcome might have been very different.

We must learn from this experience, abandon any underestimation of our enemy, and make thorough preparations to face the tribulation once again.

If some evil spirit tries to take advantage of her tribulation to rob her...

Hmph, Chu Lengyu's lips curled into a cold smile, thinking to herself: Then let them see the power of the Star Annihilation God Array!
