As for his first Extraordinary Organ, Su Zhou had long since decided what he would enhance.

His stomach and intestines—the entire Digestive System!

’Food is a supplement to the Dao. Dining on wind and drinking dew, or Grain Avoidance Cultivation, is in essence still a form of "eating nature’s spiritual energy." It’s not about taking in nothing at all. True self-sufficiency without external resources, forming a self-sustaining cycle—that’s the Celestial God Realm of the Ouroboros.’

’The path I’m cultivating isn’t the orthodox Immortal Spirit Path of the National Preceptor or other Daoist Schools. It’s a path that gives equal importance to the body and soul. Right now, I don’t need to fight; I just need to speed up my cultivation. So, for me, enhancing my digestive ability is undoubtedly the most important thing.’

’Besides, the Digestive System is essentially a collection of many organs, and it’s the largest such collection. Cultivating it first will save me a lot of effort.’

Both Sacred Geometry: Pentagram and the National Preceptor’s Five Extremes Divine Thunder True Technique contained methods for creating Spiritual Qi Organs. However, the Divine Thunder True Skill was part of the Immortal Spirit Path. It favored internal organs like the viscera, or the orifices of the head like the eyes, ears, and nose. Moreover, its goal wasn’t truly to temper the physical body. Instead, it focused on storing qi and condensing the spirit. Then, when the original body eventually perished, the Spiritual Energy contained within these organs could be used to shape the Immortal Spirit Body.

Sacred Geometry, on the other hand, was extremely balanced. It even had methods for enhancing one’s fingernails. Su Zhou even had a hunch that if he were some kind of monster, like an eight-armed serpent demon, Sacred Geometry would probably have ways to enhance all those miscellaneous arms and tentacles.

Shaking off his stray thoughts, Su Zhou gathered his Spiritual Qi and resumed his cultivation.

He mobilized a vast amount of Spiritual Power, gathering it in his stomach and intestines. Su Zhou formed countless tiny structures of spiritual qi. He then embedded them—or rather, made them take root and sprout from deep within his original flesh, transforming its very essence. The Spiritual Qi from the Spirit Pill even granted these structures an affinity for thunderbolts and the power to discharge faint electricity.

This process was different for everyone, depending on their mindset. Some people felt that forming a Spiritual Qi Organ was like forging a weapon, requiring constant hammering and tempering with Spiritual Qi. Others believed they should supply the organ with a large amount of Spiritual Qi and let it spontaneously temper and strengthen itself under the immersion.

As for Su Zhou, perhaps because he had been dealing with the Divine Wood recently and had a Wisdom Tree in his Soul Space, the process he used was akin to a tree’s growth: taking root and sprouting. He embedded countless tiny spiritual qi structures deep into his original organs. With a massive infusion of Spiritual Qi, they grew and strengthened, gradually replacing and merging with the original organs.

The moment the fusion was complete would be when the Extraordinary Organ was fully formed.

For a full day and a night, Su Zhou cultivated in the old house. He had already told his parents he might need to cultivate alone for some time. In the meantime, only Shao Qiming came by to check on the situation. After a brief chat with Yara, he left quietly without disturbing Su Zhou.

After a full day, the Spiritual Power from the Five Thunders Qi Storage Pill was depleted.

Su Zhou opened his eyes.

Ha.

He took a deep breath. The Spiritual Qi for several hundred meters around him stirred, forming a vortex with him at its center that flowed into his mouth—and that single breath lasted for a full five minutes!

Every minute, Su Zhou could absorb an amount of Spiritual Qi equal to half his original total. After five minutes, his total Spiritual Qi had reached three and a half times his original amount!

At this moment, if someone could see through Su Zhou’s abdomen, they would notice that his stomach and intestines had become exquisite and pure. They were now hazy and semi-translucent, glowing faintly like a fluorescent lamp. Spiritual Qi flickered throughout them, carrying faint electric arcs. Even the nerves, blood vessels, and spiritual qi pathways within were all clearly visible.

His first Spiritual Qi Organ was complete!

Just then, a RUMBLE LIKE THUNDER echoed from Su Zhou’s abdomen! A ravenous hunger, seeming to originate from every corner of his body, crashed over him like a tsunami!

’Crap! I completely forgot about this! The cultivation session was too long, and I haven’t eaten all day!’

Su Zhou, who had been about to take a moment to celebrate the formation of his first Spiritual Qi Organ, suddenly blanched. He felt just like the Wisdom Tree in his Soul Space, his mind filled with nothing but, ’Hungry! Hungry! Hungry!’

This wasn’t just because he hadn’t eaten for a day. The formation of a Spiritual Qi Organ was an extremely draining process that consumed a great deal of physical stamina and Spiritual Power. It consumed no less energy than fighting at full strength for a day and a night. Even though Su Zhou had the Celestial Human Cycle, the tangible toll on his physical body was unavoidable.

Furthermore, cultivating a Spiritual Qi Organ would temporarily cause a major upheaval in the cultivator’s spiritual qi system. Therefore, unless one could reshape several Spiritual Qi Organs at once, they had to wait for a period of time after completing each one. Only after harmonizing the Spiritual Qi in their body could they continue their cultivation.

Although he was starving, Su Zhou had already prepared for this situation. Without a second thought, he rushed into the old house. Amidst Yara’s lazy congratulations, "Well now, you finally succeeded, huh? Congrats," Su Zhou grabbed his phone and called Shao Qiming.

[What’s up, Azhou?]

"It’s an emergency, bro! Quick, help me order a table full of food from any restaurant! I’m starving to death!"

[No problem—I already figured as much. I’ll send you the location. Just hurry over.]

「Several hours later.」

It was only after Su Zhou had eaten his fill at a Sichuan restaurant, finally dispelling that indescribable hunger that seemed to emanate from every cell in his body, that he let out a long, satisfied breath.
