*Chapter 1: The Opening Full-Level System, Heaven-Defying Comprehension!*

"????"

"Where is this place? Why is it pitch black all around? I can't even stretch my hand..."

After being hit by a large truck and regaining consciousness, Xiao Yan struggled to open his eyes, only to find that he couldn't.

Even more troubling, his entire body seemed to have issues.

He felt unprecedentedly weak, as if he had returned to the state of an infant. He couldn't even move his hands or open his eyes.

The only thing Xiao Yan could sense was that he was now submerged in some warm water.

Just as Xiao Yan was pondering what had happened to him, a mechanical voice abruptly echoed in his mind.

*[Ding, congratulations to the host for successfully transmigrating. The Full-Level Comprehension System has been bound.]*

"Successfully transmigrated?" Xiao Yan murmured, feeling a storm of emotions surging within him.

So, he really had been trucked into another world!

And he had even become a fetus.

At this moment, the conversation of a few people outside confirmed his situation.

"Young Master, rest assured. The Young Mistress's body is perfectly fine. I will prescribe a few fetal-stabilizing medicines, and the young master will certainly be born healthy."

Xiao Zhan breathed a sigh of relief and thanked the old man, "I'm grateful to you, Old Han."

"No need to be so courteous, Young Master," the old man replied with a slight smile as he seriously wrote the prescription.

Qin Yueyao, who had already given birth to two sons, had some experience. Gently caressing her slightly protruding belly, she said, "There's really nothing to worry about. It's just that this little guy is a bit more mischievous than the others."

Xiao Zhan smiled, "It's better to be cautious."

Knowing his situation, Xiao Yan calmed his mind and began studying this so-called Full-Level Comprehension System.

After a few minutes of exploration, Xiao Yan discovered that this system was quite simple.

It didn't have any flashy features; it simply elevated his comprehension to the maximum level.

"What can having full-level comprehension do?"

Xiao Yan murmured, thinking that the fetal stage seemed to hold some form of innate energy.

If he could start utilizing it at this stage, he would surpass ordinary people in everything he did in the future.

With this in mind, it only took a moment before Xiao Yan suddenly felt like he had grasped something, though it wasn't quite clear.

A strong sense of drowsiness washed over him, and Xiao Yan didn't resist.

After all, he was now a fetus and needed to rest and grow.

He didn't know how long he slept, but when he awoke again, he felt refreshed and finally understood the power of his system.

It didn't require him to complete any tasks; it simply elevated his comprehension to an extraordinary level.

What might take a genius ten years to learn could take him just one day, or even less.

And if he wanted to comprehend something specific, what would take a genius decades or centuries to study might take him only a few months or days.

After a satisfying sleep, Xiao Yan found himself with a clearer understanding of how to use the innate energy within his fetal state.

For the next half month, whenever he woke up, he would ponder over the usage of innate energy and then go back to sleep when he was tired.

Repeating this cycle, Xiao Yan finally achieved a concrete result.

*[With your extraordinary spiritual perception, you sensed your innate fetal breath. You had an epiphany and created the "Innate Fetal Breathing Technique"!]*

Xiao Yan was surprised by the system's intelligence. He had indeed come up with a technique suitable for a fetus to cultivate.

However, he hadn't yet come up with a proper name for it.

*["Innate Fetal Breathing Technique": Using a trace of innate energy as the catalyst, it absorbs and converts the nutrients provided by the mother to enhance the body's constitution and improve the foundational aptitude.*

*Note: This technique can only be practiced by a fetus.]*

Having completed the comprehension of the technique, Xiao Yan immediately began to practice the "Innate Fetal Breathing Technique."

Since it was a technique for fetal cultivation, practicing it just once allowed the technique to operate automatically.

Xiao Yan could continuously enjoy the benefits of cultivation.

The innate energy circulated endlessly, and Xiao Yan felt like countless strands of gentle energy were surging into his body.

With the influx of this gentle energy, Xiao Yan noticed a slight increase in his strength and subtle growth in his body.

Experiencing this benefit, Xiao Yan, who had spent half a month in deep contemplation, decided to give himself a break and peacefully drift back into sleep.

During this process, the "Innate Fetal Breathing Technique" continued to operate automatically, without any effort on Xiao Yan's part.

A little over a month later.

"Madam, your appetite has increased quite rapidly lately. Are you sure there's nothing wrong?"

Watching his wife, who had already eaten enough for two grown men and was still eating, Xiao Zhan couldn't help but worry.

His concern wasn't unfounded; his wife's appetite had grown to an alarming level.

Each meal, she consumed what would typically feed an adult man for three days. Moreover, this was not coarse food but meticulously prepared delicacies from the Xiao family kitchen.

What was more astonishing was that despite eating so much, apart from her slightly larger pregnant belly, she didn't gain any weight.

Qin Yueyao sipped some tea, a gentle smile of motherly love on her face, and replied, "I asked Old Han to check on me this time. He said there's nothing wrong; it's the child's unusual constitution. He even suggested that I eat more."

Hearing this, Xiao Zhan nodded slightly and relaxed a little.

Old Han was quite accomplished in the field of medicine and was a well-known physician in Wutan City. If he had the qualifications of an alchemist, even the city lord wouldn't dare to neglect him.

Listening to the couple's conversation, Xiao Yan smiled faintly.

This situation wouldn't need to continue in the future.

*[You used the "Innate Fetal Breathing Technique" for further analysis and, after days of practice and study, you had an epiphany. You created the "Innate Fetal Breathing Technique" Version 2.0!]*

**["Innate Fetal Breathing Technique" 2.0: Using a trace of innate energy as the catalyst, it absorbs and refines the energy of heaven and earth through the mother to form Dou Qi, strengthening the body's constitution and enhancing foundational aptitude.

Moreover, by circulating Dou Qi, the mother can also experience a similar effect to cleansing the meridians and marrow, greatly enhancing her constitution and foundational aptitude!**

*Note: This technique can only be practiced by a fetus.]*

Reviewing the "Innate Fetal Breathing Technique" Version 2.0 again, a delighted smile appeared on Xiao Yan's face.

This time, it had taken him more than a month.

Originally, Xiao Yan planned to sleep through until his birth.

However, life inside the womb was too boring.

Moreover, because he had cultivated the "Innate Fetal Breathing Technique," his mother in this world had to eat an enormous amount of food every day to make up for the technique's consumption.

Xiao Yan felt somewhat apologetic about this.

The cultivation of the "Innate Fetal Breathing Technique" drew energy from the mother.

With nothing else to do, he began upgrading the technique.

The first breakthrough was to make the technique no longer draw energy directly from the mother but instead use her to absorb and refine the energy of heaven and earth.

In this way, the technique's cultivation would be supplied by the energy of heaven and earth, so the mother wouldn't need to eat such a massive amount of food.

Additionally, it would be best if the mother could also benefit, improving her constitution and physical qualities.

Although the enhancement might not show much effect in a day or two, over time, it would result in a transformative improvement.
