Volume 4: Phoenix Crying in the Ninth Heaven

**Section 1: The cosmic haze crisis**

The Imperial Hospital's medicine cauldron suddenly erupted, transforming Sibao's freshly added herbs into fluorescent lollipops. Sanbao rolled into the alchemy room, holding a milk bottle emitting black mist: "Mother! The calamity spirit is live-streaming its food on TikTok! It's saying it wants to turn Chang'an into stinky tofu!"

Gu Jinghong looked up from "Plague Theory" and found that the medicine mist was fighting with the barrage: [PM2.5: This treasure is going for cyberpunk style today] [Miasma: If my friends can get rockets, I will eat the moat alive]

Parenting system pops up holographic gas mask:

- Acupuncture bronze figure wearing a luminous bracelet and performing a "detoxification dance"

- The medicine grinder scrolls "Please cleanse" barrage

- The most outrageous thing is the Medicine King Cauldron, the ears of which are covered with small advertisements for "Refining Disaster Qi for You"

- The imperial physician lamented: "They use disinfectant to make milk tea!"

"Eco-diaper bomb detected," the system showed a comforting doll, "Start "Baby Environmental Protection Class" 1.0!" The alchemy room transformed into a children's chemistry corner.

The four-treasure dragon horn scanned the particle stream: "Pollution index = the number of times Daddy forgot to lather the baby bottle x 27!" Before he could finish his words, the Imperial Astronomical Observatory's "smog color code card" slammed overhead: "The Northeastern Evil Qi mixed with the Northern Wei Dynasty sandstorm combo is unsold!"

The bronze sword spirit floated by while chewing mugwort: "Young master, the Kan position..." Twenty-eight mechanical cleaners broke out of the ground, and their brooms were engraved with "Cleaner No. 27 is carrying out the 27th civilization disinfection experiment."

**Section 2: Cute Baby’s Garbage Sorting Battle**

"This disaster requires a blood sacrifice..." Just as the Imperial Master pulled out the black dog blood, Sibao suddenly ejected a holographic trash can: "Original operation detected, bound to the 'Infant and Child Waste Sorting Guide'!"

The quadruplets' hardcore operation subverts metaphysics:

- Sanbao uses blockchain to label disaster gas as "hazardous waste"

- Sibao transforms a dragon horn into a 5G air purifier (play the environmental version of "Dig, Dig")

- The system pours Yakult into the poisonous fog (the black gas condenses into a fluorescent "recyclable" sign)

- Erbao puts on a medicine pot and wears a diaper (the pot's belly shows an absorption progress bar).

"The latest purification plan!" The system switched to a nursery rhyme voice: [According to the host's flustered index, start the rocking car refining mode] The holographic screen popped up:

- Plague transcoded into rainbow clay

- Miasma is encrypted into the sheet music of "Twinkle Twinkle Little Star"

- Yaowu activates the "saliva towel" filtration system

Suddenly, the medicine cauldron exploded into a rainbow, and the mechanical cleaner popped up a warning: [The 27th disinfection experiment failed...] Sibao climbed onto the mechanical arm, and the Longjiao data stream cracked the program - the interstellar picture showed that the male protagonist was bound by twenty-seven pollution chains, and the experimental log was marked "2023.02.27 Father's Love Purification Day".

**Section 3: Holographic Dad Air Tank**

As the mechanical cleaner started the incineration process, Sibao suddenly took out his electronic pacifier and said, "Activate the ultimate secret - Daddy's sleep-inducing breathing method!"

The system suddenly blue screen pops oxygen bubbles:

- Sanbao Abacus generates a "lift high" negative ion dynamic image (poison mist turns into rainbow lollipop)

- Sibao Dragon Corner Projection Baby Monitor (male protagonist measures air quality VR late at night)

- Mo Dao raises the glowing diaper flag (the calamity energy condenses into early childhood building blocks)

- 100,000 Plague Chorus "Breathing Song" dance digging digging

The mechanical cleaners all shut down, their brooms transforming into fluorescent baby bottles. A crack in a medicine cauldron reveals an interstellar childcare surveillance video—in which the male protagonist uses calamity energy to blow bubbles at the four babies, each one printed with the words "Canned Fatherly Air."

"Experiment 27 failed..." A mechanical voice echoed as the poisonous zone shrank into a child's chemistry box. Sibao fished out a quantum gas mask from the black mist, and a lunar ecological park appeared on the lens. "Daddy said that every breath he takes is in the shape of my love for you~"
