Time, another day passed without him realizing it.

This was already the fifth day since Zhang Ruohan left.

Li Yun had just finished a round of observation.

The cognition points on the panel had reached around 1.4 million again. When he got up to eat something, he found that he had unknowingly eaten all the food Zhang Ruohan had left behind.

"Holy crap!"

"It's all gone?"

"Senior Sister Zhang hasn't returned yet, so won't I be starving?"

Li Yun was a bit speechless.

He didn't think Senior Sister Zhang did it intentionally or forgot about him. After all, she was an Inner Sect Disciple, so it was hard to guarantee she wouldn't be tied up with some trivial matters.

There was nothing to eat, and he couldn't find any alternative food in the Valley.

Li Yun simply endured it, using cultivation to distract himself, lest thinking about food make him feel even hungrier.

His cultivation had already reached the Body Tempering Thirteenth Level through cultivating the 【Primordial Chaos Stance】. Further tempering was ineffective. Continuing to cultivation would only allow him to gain more insight into the Primordial Chaos True Intent, resulting in subtle progress on the true meaning level. This should be a good thing, but the effects wouldn't be visible in the short term.

So, Li Yun temporarily stopped cultivating the 【Primordial Chaos Stance】 and instead focused on the 【Reversing Fate Art】 that he had always been thinking about.

The 【Reversing Fate Art】 went from never having started to getting started, costing ten thousand cognition points.

From getting started to initial success, it cost one hundred thousand cognition points.

From initial success to proficiency... Li Yun didn't know how many cognition points it would require for now. However, even if it increased tenfold again, his current cognition points of around 1.4 million were definitely enough.

He didn't hesitate.

He went straight to it!

As expected, this thing was truly a big consumer of cognition points.

As soon as the upgrade began, one million cognition points were gone.

The 【Reversing Fate Art】 also advanced from the realm of initial success to the realm of proficiency.

Li Yun's expression was slightly excited.

After stepping into the realm of proficiency, the mysteries of breathing and blood circulation he had previously comprehended... had many more profound aspects added, becoming more complex and also more complete.

It also made him understand why it was so painful when he used the 【Reversing Fate Art】 before.

A large part of the reason was that the 【Reversing Fate Art】 in the realm of initial success was not complete enough and had flaws.

The 【Reversing Fate Art】 after reaching the realm of proficiency was more complete and had fewer flaws.

Naturally, it was also more suitable for cultivation.

On the spot, Li Yun assumed a posture and began attempting to cultivation.

That familiar feeling of blood boiling, impacting his internal organs, and his body temperature soaring appeared once again, but it was clearly not as intense as before.

Instead, it was gentler and slower.

In this way, although his body temperature continued to rise, making him still feel a painful torment, because the stimulation was not as fierce, it miraculously allowed him to endure it.

Especially now, things were different from before.

His cultivation had reached the Body Tempering Thirteenth Level, and his physique had improved in all aspects, which was incomparable to before.

In the end, this time cultivating the 【Reversing Fate Art】, he actually managed to persevere for a full half hour before being unable to hold on and being forced to stop.

The effect, however, was gratifying!

Pulling up the System panel to take a look, the Aptitude line had actually risen from Fifth Grade Middle to Fourth Grade Lower!

"It actually even crossed a grade!"

Li Yun was overjoyed!

One must know that with nine grades of Aptitude, the difference between each grade is huge. The difference of one grade between Fifth Grade and Fourth Grade is incomparable; they are completely two different levels of things.

Taking the example of reversing Acquired to Innate, although the success rate of reversing to Innate is still extremely low for ordinary people with Fourth Grade Lower Aptitude, compared to Fifth Grade Aptitude, the improvement is definitely at least tenfold.

To verify the effect of Fourth Grade Aptitude.

Li Yun quickly sat down again and once more observed the wind at the Valley entrance.

【Observing the rhythm of the wind, cognition points +20】

It was +10 before, now it's +20.

It doubled!

Don't underestimate this doubling. You must know that the gain in cognition points is calculated by the second. Originally, one hour yielded 36,000 points, but now it will become 72,000 points per hour.

If he observed for ten hours a day, he would gain an additional 360,000 cognition points out of thin air.

"However, I'm so hungry... ah..."

He didn't know if it was because cultivating the 【Reversing Fate Art】 had improved his Aptitude, which also invisibly increased his body's consumption, but Li Yun suddenly felt a strong sense of hunger.

He was so hungry that he felt almost dizzy.

But at this time, Zhang Ruohan still hadn't come, and he himself didn't know lightness skill, so it was impossible for him to leap over this three-hundred-meter cliff.

He was essentially trapped here.

Could it be that he was about to become the first person in history to have both his Aptitude and cultivation improved, only to starve to death in the Valley due to lack of food?

It shouldn't be this tragic!

Li Yun shook his head, stood up, and prepared to search the Valley again. Even if he had to eat grass, he couldn't really let himself starve to death here.

But just then, his gaze suddenly paused.

Looking at the constantly wailing wind at the Valley entrance, he suddenly had a flash of inspiration.

"That's not right..."

"This Valley isn't actually completely sealed off. Shouldn't that Valley entrance be a way out?"

"How could I be so stupid? I observe there every day, but I never thought about trying to walk out through the Valley entrance?"

Seeing the hope of getting out, Li Yun suddenly felt a bit more energetic.

Without hesitation, he walked towards the Valley entrance.

As he approached the Valley entrance, the wailing wind was clearly swirling very fiercely, forming a strong tearing force.

The wind blades were like swords, hitting his skin and causing a faint pain.

Li Yun suddenly understood why Zhang Ruohan had proactively left him food before she left. It was because Zhang Ruohan knew that with his strength a few days ago, he wouldn't be able to withstand the wind force at the Valley entrance.

At that time, with his Fourth Level of Body Tempering cultivation, whether it was strength or physical toughness, if he dared to try and walk out, there would only be one outcome: being swept away and killed by the wind!

But this time, it was different.

Li Yun's cultivation was already at the Body Tempering Thirteenth Level. His strength could burst up to three thousand jin, and his physical toughness was even stronger than fierce beasts like tigers and leopards. Although the wind at the Valley entrance caused a faint pain when hitting his body, it didn't tear his skin, only leaving faint white marks on it.

Walking against the wind like this, he walked for about ten minutes.

It actually allowed him to pass through the Valley entrance and walk along a narrow mountain path into another Valley.

Looking now.

Li Yun couldn't help but be dumbfounded.

This Valley was wider, but it was a desolate wasteland. A faint wind blew in from a narrower mountain crevice ahead, making no sound, yet it caused the vitality of this Valley to wither.

Not only was there no sign of vegetation, but the ground was also covered in tiny white bones, which were clearly the remains of various birds at a glance.

At this moment.

Just then, a fallen leaf drifted down from above the Valley. Before it even landed, it silently disintegrated, turning into dust.

Also at this moment.

Li Yun suddenly felt a sharp pain on his skin.

He looked down.

And was horrified to find that his exposed skin had somehow developed dense sword marks, with faint traces of blood seeping out. Blood had already dripped onto the ground along his ten fingers.

"Damn..."

Li Yun instantly felt a wave of fear.

Without a word, he turned and ran.

Like fleeing for his life, he returned to the previous Valley through the narrow mountain path and fell powerlessly onto the ground. By this time, he had become a bloody mess.

Hunger and blood loss caused him to directly fall into a coma.
