Junior sister, I really need to control you.

Inside the grotto, under the moonlight.

After receiving thirty and fourteen years of cultivation respectively, Li Yinsheng was already extremely familiar with this place.

But this training was different from the previous ones.

He developed a Blood Refining Pivot within his body to aid in body refinement, and he also cultivated the True Blood Refining Secret Manual.

Previously, when he was cultivating in the outside world, he did not try to use his magic power to envelop the Blood Refining Pivot in order to stop its dissipation.

This is far too mentally taxing, severely reducing cultivation time, and just as the female shopkeeper said, the benefits are not great.

Even if left unattended, the Blood Refining Pivot can still exist for five or six years.

However, now that he's inside the cave, he has to divide his attention between two tasks, constantly diverting his magical power to stabilize the Blood Refining Pivot.

This reward alone is equivalent to thirty-four years of cultivation.

Although they cultivated tirelessly in the cave, the actual cultivation time was not thirty-four years, but it was definitely more than ten years.

If left unattended for such a long time, the Blood Refining Pivot would have dissipated two or three times over.

Fortunately, cultivating in the cave does not consume any mental energy; however, the fatigue and discomfort caused by the continuous mental energy consumption still exist.

If we compare mental exertion to bleeding from an injury, then normally, while the wound is in pain, the blood will gradually drain away.

But inside the cave, although the wound still hurts, the blood will never run dry.

Li Yinsheng focused his mind and gathered his energy, using his magic power to envelop the Blood Refining Pivot at his heart, which had already transformed into a ball of pure Bing Fire energy, preventing the Bing Fire energy within from dissipating further. He then began to circulate the Qingxuan True Scripture.

……

After a long while, Li Yinsheng opened his eyes and slowly exhaled.

Since the surrounding scenery remained unchanged, the only reference point he could use to judge time was the change in his own cultivation level.

He estimated that his current cultivation level was around seventy years.

Just now, his Qingxuan True Scripture broke through to the ninth level, and his True Blood Secret Manual is also close to the third level.

The breakthrough to the ninth level brought about a qualitative change in magical power. The pure spiritual energy that had been fully restored in the dantian spontaneously gathered and condensed, transforming into a layer of hazy, clear light that illuminated the entire dantian.

The magical power cultivated from the Pure Profound Scripture appears as a translucent pale blue to the naked eye, but the Pure Profound Divine Light that emerges after reaching a deeper level of cultivation is quite different.

The Pure and Mysterious Divine Light has no color.

Li Yinsheng raised his hand, and the light that appeared in his palm was as clear as water, somewhat similar to the cool moonlight falling from the full moon above.

He could sense that after the pure spiritual energy was sublimated into the pure and mysterious divine light, its quality was improved by leaps and bounds.

However, to truly grasp the wonders of this Pure Mysterious Light, one must experience it firsthand.

Li Yinsheng first withdrew the Pure Profound Divine Light, then flicked his finger lightly at the lotus lake in front of him.

A beam of white light flew from his fingertips.

Driven by the profound magical power gained from seventy years of cultivation, the white light transformed into a crescent-shaped blade of light several feet wide, unleashing a piercing whistling sound.

In an instant, the blade flashed sixty or seventy feet, severing all the lotus flowers and leaves along the way and clearing a clean waterway.

Li Yinsheng was somewhat surprised.

He hadn't used the Pure Profound Divine Light yet; he had only briefly tested the only spell he knew, which was specifically for killing and fighting enemies.

This technique is called the White Blade Technique. It is used exclusively for combat. It does not require hand seals, incantations, or external aids. With a single thought, it can unleash a blade of light capable of cutting through iron and stone.

However, its advantage lies in its low energy consumption and rapid casting speed, rather than its power.

For beginners, the blade's light is only two or three feet long, and at most it can fly a few feet away. Although its power is enough to cut an ordinary armored soldier in half, its speed is not fast, and even ordinary martial arts masters have a chance to dodge it.

When Li Yinsheng had cultivated for twenty years, he could fly more than ten zhang away with a single spell, cutting down several large trees as thick as large bowls along the way. His speed was something that ordinary people could not avoid.

He had even deliberately held back some of his strength in that attack, but its power, range, and speed had all exceeded his expectations.

A gentle breeze swept by, and the lotus flowers and leaves scattered in the water returned to their original state, as if nothing had just happened.

Li Yinsheng wasn't surprised; given the wonders of this grotto-heaven, its ability to self-repair was perfectly normal.

He flicked his finger again, and this time, with a thought, a wisp of pure and mysterious divine light merged into the White Blade Technique.

In an instant, the blade light, which was originally about ten feet wide, expanded to more than three feet, silently sweeping across two hundred feet. Its speed was so fast that Li Yinsheng himself only felt that it was "a flash by".

"hiss……"

Li Yinsheng nodded in satisfaction.

With just a touch of the Pure Profound Divine Light, the power of the White Blade Technique more than tripled.

The main reason is probably that the melee technique itself is too simple and low-level, so it becomes so exaggerated under the blessing of the divine power of the Pure Profound Divine Light.

However, it shouldn't be difficult to double the power of those powerful spells.

With great interest, Li Yinsheng tried a few more times. He flicked his fingers and several white blade techniques, enhanced with the divine light of Qingxuan, flew out from all directions, carving out several waterways two to three hundred feet long on the lake surface in the blink of an eye.

After trying it for a while, Li Yinsheng shook his head again.

These few melee attacks consumed very little of his magical power, but the Qingxuan Divine Light was reduced by more than 10% because of them.

Moreover, in his perception, the recovery speed of this Pure Profound Divine Light was even slower than that of the Pure Spirit Qi.

More than 10% of the damage has been done, and it will probably take at least half a year to recover.

The good news is that he will have to endure who knows how many more six-month periods in this miserable world.

He originally wanted to take advantage of the ample time to restore the Pure Profound Divine Light and try to use it to cleanse his meridians and marrow.

Unfortunately, although the Pure Profound Divine Light can cleanse one's marrow and bones, one cannot cultivate during this period.

However, this grotto-heaven required him to cultivate only inside and not to do anything unrelated to cultivation.

He only spent half a cup of tea's time trying out the Pure Profound Divine Light when golden characters appeared on the white jade platform beneath him, reminding him not to lose focus, or he would be sent away.

With a sigh, Li Yinsheng could only close his eyes and continue to endure the burning pain of the Bing Fire Blood Refining Technique, while circulating the Qingxuan True Scripture.

……

There is no calendar in the cave; when the year ends, one is unaware of the passing years.

Li Yinsheng, immersed in cultivation, was unable to keep track of time; he only knew that his cultivation level was approaching the century mark.

The Pure Mystery Scripture is getting closer and closer to the tenth level, and the True Blood Secret Manual has just reached the fifth level, but it is still quite a distance from the sixth level.

But he knew very well that his cultivation this time would not last a hundred years.

Before receiving the reward, his cultivation level had barely reached the twenty-year level.

The three awards were for thirty years, fourteen years, and this thirty-four years, totaling ninety-eight years, which is exactly two years away from the centenary.

Therefore, he will be kicked out when his cultivation level is close to a hundred years.

But if his feeling is correct, with his current cultivation of over ninety years, he is very close to breaking through to the tenth level of the Qingxuan True Scripture.

If his guess is correct, a hundred years of cultivation is not only the threshold for becoming a True Person, but also just enough to break through the tenth level of the Pure Profound True Scripture.

The Pure Profound Scripture clearly states that only after reaching the tenth level, stabilizing one's cultivation after the breakthrough, and ensuring a secure foundation, can one advance further and achieve the status of a True Person using the methods recorded within.

This is also why the Qingxuan True Scripture is a superior practice of the Xuanzhen Temple.

The common practices in Taoist temples would never include methods for achieving true immortality.

Although he was still a little far from becoming a True Person, Li Yinsheng had no intention of giving up on the tenth level of the Qingxuan True Scripture, which was right before his eyes.

Breakthroughs in cultivation techniques depend on one's own cultivation level, but it is not strictly necessary to maintain consistent cultivation for a full year before a breakthrough can be achieved.

For example, breaking through to the ninth level of the Qingxuan True Scripture requires seventy years of cultivation, but this is not entirely absolute.

Depending on a cultivator's own talent, comprehension, innate ability, and even the guidance of their master, the cultivation level required to break through to the ninth level can fluctuate around seventy years.

For cultivators with good talent, guidance from renowned teachers, or whose temperament, aptitude, and spiritual qualities are more compatible with the Qingxuan True Scripture, it is possible to break through to the ninth level ahead of time, even if their cultivation is five, six, or even seven or eight years lower.

Those cultivators with poor talent, poor compatibility with cultivation techniques, or whose cultivation is superficial due to "consuming too many pills" or "receiving initiation" may need to accumulate another seven or eight years of cultivation before they can break through.

Of course, cultivation level is a prerequisite for breakthroughs in cultivation techniques. It's normal to be a few years earlier or later, but the difference won't be too drastic.

For example, if someone only has forty or fifty years of cultivation but dreams of reaching the ninth level of the Qingxuan True Scripture, then that's just wishful thinking.

Li Yinsheng himself has inferior aptitude and relatively poor talent. Moreover, he relies entirely on his own exploration and understanding to practice his skills, without much guidance from a master.

However, his temperament and innate talent were well-suited to the Qingxuan True Scripture, and his cultivation was entirely the result of his own painstaking practice, which made it extremely solid.

He even made some progress in the True Blood Secret Manual, making his body much stronger than before, with abundant essence and energy, which also slightly helped him break through the Qingxuan True Scripture.

With his disadvantages offset by his advantages, and having cultivated for seventy years, he broke through to the ninth level with just a slight attempt.

In fact, he had a vague feeling at the time that with the foundation he had laid over the years, even if he only had inferior aptitude, he could have broken through to the ninth level two years earlier.

At that time, he was still far from leaving the cave heaven. Even if he had broken through two years earlier, he would still have cultivated for so long, so there was no need for that.

But now he's only two years away from breaking through, and he's being sent away from the bottleneck of the ninth level like this, which is truly disheartening.

Especially since this grotto-heaven, although it doesn't accelerate cultivation, doesn't deplete mental energy no matter how one cultivates, making it, in a sense, even more suitable for breakthroughs—

Breaking through a cultivation technique is the most mentally taxing process.

It's like walking on a narrow bridge. Although the road ahead is flat, you have to be fully focused while walking. If you make a mistake or lose your composure, you'll fail completely.

The state of mind and spirit that is never depleted in the cave is very advantageous for breakthroughs, and Li Yinsheng did not want to waste it.
