"Where can I find this 'eternal number'?" Su Li felt that this was even more difficult than refining the old times.

A glimmer of wisdom flashed in Dabao Su Chen's eyes, and he pointed at Su Li's belly: "There is no need to seek outside. This 'number' is far away in the sky, but it is close... in my mother's belly."

Everyone: “!!!”

Su Li subconsciously covered her stomach: "Chen'er, you mean..."

"The new life nurtured in Mother's womb," Dabao Su Chen's voice carried the ethereal quality of someone who understood the mysteries of heaven. "This life is nurtured by the blood of my parents, the promise of Heaven (a favorable environment), the blessings of my adorable baby (the daily illumination of Qibao's strawberry seal), and even the hope of rebirth in this world after catastrophe! Its initial heartbeat frequency, subconsciously nurtured by Mother's Medicine Saint talent, has achieved a near-perfect, life-enhancing... **'Innate Fetal Heart Rhythm'**! This rhythm is the closest prototype to the 'eternal number'! We only need to capture it, sublimate it, and freeze it, and it can serve as an anchor point for Heaven's Way!"

[Ding! Genius! Chen Bao is a cosmic CFO!] The system screamed excitedly, ['Innate Fetal Heart Rhythm'! Absolutely constant (each life is unique and stable), all-encompassing (life is the carrier of all rules), and full of vitality (nonsense!)! Perfectly meets the requirements! Plan steps:]

1. **Capturing Rhythm**: Mother Su Li uses her Medicine Saint innate inner vision to perceive, while eldest son Su Chen uses the Causal Abacus to simultaneously analyze and record.

2. **Sublimation and Freeze**: Inject the captured rhythmic data stream into Sibao Su Qi's 'Abundant Seal' strawberry birthmark! Utilizing the power of the Heavenly Dao's promise and the blessings of all living beings, combined with the system's overclocked computing power, refine, sublimate, and solidify it into a concrete **'Number' rune** imbued with the eternal Dao rhythm!

3. **Anchoring the Heavenly Dao**: Dad Xiao Jue shatters the void, inducing the Tai Chi Dao rhyme and embedding the rune into the core rules of the Heavenly Dao! This completes the final anchoring!

"Qiqi's strawberry... is it going to represent my little brother/sister's heartbeat?" Fourth child Su Qi curiously touched her glowing strawberry birthmark, then carefully touched her mother's belly, her little face full of curiosity and anticipation. "Qiqi will protect it!"

Su Li and Xiao Jue looked at each other, and saw the shock and determination in each other's eyes. For the future of this world, and for the new life that was about to come, this risk must be taken!

**Section 2: Fetal Heart Symphony and the Birth of the Strawberry Rune**

The plan was launched! The location chosen was the top floor of the "Pacifier Gold Bank" headquarters, which was blessed by the dual blessings of the "Wind Adjustment Seal" pacifier and the "Abundance Seal" and had the most peaceful energy.

Su Li sat cross-legged in the center, her hands gently caressing her abdomen, eyes closed, her mind focused. Her "Medicine Saint" talent was activated to its fullest potential, no longer acting on external objects but, like the most sophisticated scanner, gently probing the thriving life within her belly. Soon, she distinctly sensed a faint yet incredibly steady, vibrant rhythm—dong! da! dong! da! It was like the most primal, moving drumbeat in the universe.

"Captured the fetal heart rhythm! The frequency is stable! Energy level: life origin level!" Su Li said in a deep voice.

"Abacus synchronization activated! Analysis begins!" Dabao Su Chen sat cross-legged across from his mother, his small body bursting with astonishing concentration. The suspended shadow of the causal abacus suddenly expanded, transforming into a vast golden abacus matrix encompassing the two of them! Countless golden beads spun like stars, precisely capturing and recording every subtle fluctuation of the "dongda" rhythm, transforming it into a vast ocean of data streams! The sound of the beads colliding was no longer a crackling sound, but a unique "data symphony" that resonated with the rhythm of the fetal heart!

"Qibao! Get ready!" Su Li shouted.

"Yes!" Sibao Su Qi nodded vigorously and stood beside her mother. The strawberry birthmark (fengrongyin) on her little face burst into an unprecedentedly brilliant red light! The light was no longer warm, but instead carried an almost sacred aura, carrying the promise of heaven and the blessings of all people! The red light formed a funnel-shaped vortex, aiming at the core where Su Li's lower abdomen and the Dabao Abacus matrix intersected!

"Inject!" Dabao Su Chen pointed suddenly with his little hand!

The vast and pure fetal heart rhythm data stream analyzed by the abacus matrix was like a golden river bursting its banks, surging towards the red vortex formed by Sibao Suqi's strawberry birthmark!

"Ah!" Sibao Su Qi exclaimed softly, her small body trembling slightly. The moment the massive data stream poured into the strawberry birthmark, it was as if countless "little drumbeats" were beating in her mind! Her face instantly became incomparably solemn, as if bearing a tremendous weight! The light of the strawberry birthmark turned from red to gold, then from gold to white, finally converging into an indescribable chaotic light that seemed to contain the artistic conception of the universe at its inception!

[Ding! This system's overclocked computing power is connected! Tempering and sublimation begins!] The venomous system's voice was unprecedentedly serious. [Eliminate redundant fluctuations! Extract the true meaning of life! Integrate the promise of the heavens! Brand the wishes of all beings! Target: Eternal Number Rune! Condensate!]

The chaotic light of the strawberry birthmark spun and compressed crazily! Sibao Su Qi bit her lip tightly, beads of sweat oozing from her forehead. But she persevered, concentrating all her energy on the birthmark. She had only one thought in her mind: "Protect my brother/sister's heartbeat! Become the most powerful symbol! Help Grandpa Tiandao!"

Time seemed to freeze at this moment. Only the thumping of the fetal heartbeat, the symphony of data from the abacus beads, and the chaotic light within the strawberry birthmark, which grew increasingly solid and exuded an aura of eternity, danced.

finally!

When Sibao Su Qi felt that he was about to give up, the light of the strawberry birthmark suddenly retracted inward!
