Li Tianyi quickly set up a makeshift fire outside, keeping himself extremely busy.

"Brother Tian, ​​is there anything else?" Wang Xue'er asked, holding up an empty bucket.

"Not for now!" Li Tianyi said, touching the yellow mud. "Oh, by the way, see if there are any extra large iron pots in the storeroom. No need to bring them, I'll get them later!"

"Okay!"

After they left, the construction of the makeshift stove was nearing completion.

After checking several times to make sure there were no problems, they placed several large iron pots on the stove, filled them with water, and started a fire...

Just as the water was about to boil, Su Wanruo's voice came from inside the house: "Brother Tian, ​​come in and help!"

"Here I am!"

Just as I was about to push the door open, another voice called out, "Put on your gas mask!"

Li Tianyi quickly made sure he was properly seated.

Inside, the room was shrouded in mist, with extremely low visibility, and only the outlines of people could be vaguely seen.

"What do you need me to do?" Li Tianyi asked.

"I'll remind you then!" Su Wanruo stared intently at the changes inside the medicine barrel, then suddenly shouted, "Throw in a Heartbreak Grass!"

Li Tianyi threw a plant out of the system space.

A moment later, two more plants were left behind.

The originally light black liquid is turning dark black.

"Aconite!"

"Arsenic!"

The two highly toxic substances entered, and the water immediately turned pitch black.

"The next step is crucial; it must be precise, or my little sister will surely die!" Su Wanruo said solemnly.

Li Tianyi took a deep breath and nodded.

Su Wanruo pressed the stopwatch to start timing.

"Centipedes, toads, poisonous snakes, poisonous spiders, scorpions!"

For every one she called out, Li Tianyi would release it using the system space, with perfect timing.

Su Wanruo gave her an approving look.

As time went on, the color inside the bucket gradually turned black and reflective.

"One pufferfish!"

As soon as it entered the liquid, the color of the medicine became lighter.

"One blue-ringed octopus tentacle!"

As soon as the potent toxin landed, the surrounding area turned blue.

"Throw another pufferfish!"

The blue toxins are suppressed, and the body gradually turns black.

"Three tentacles of a blue-ringed octopus!"

The two extremely potent toxins, black and blue, are incompatible and are locked in a fierce battle.

Su Wanruo smiled faintly and threw a handful of yellow Chinese herbs into the bucket. The balance was instantly broken, and the toxins began to mix.

This process was extremely slow, and Li Tianyi felt sleepy several times.

"I'll call you later, then throw in the pufferfish and the remaining blue-ringed octopus at the same time!" Su Wanruo was a little nervous.

Li Tianyi placed his hand on the edge of the wooden bucket, ready to strike at any moment.

In about five minutes, the two toxins completely mixed, and the water turned pale yellow.

"Now!"

The newly compatible toxins could not tolerate outsiders, and they attacked with all their might, while the deadly toxins softened...

One hour and half an hour later.

The bucket gleams with a pale golden light, giving you the illusion of being bathed in sunlight.

"Mission accomplished, we can let my little sister in now!" Su Wanruo said with a sigh of relief, her face relaxed.

Li Tianyi went to his sister's bedside, lifted the blanket, and immediately turned his head, "Why isn't she wearing any clothes?"

"You can't wear clothes during a medicinal bath!" Su Wanruo continued, "Just clear your mind of all distractions!"

Li Tianyi calmed himself down and slowly embraced Xiaoman. The smooth, creamy touch made it hard for him to remain calm.

"Li Tianyi, are you even human? She's my sister, my sister!" he cursed inwardly.

My anxious heart is gradually calming down.

"Put her in, but make sure the medicine doesn't flow into her mouth or nose!" Su Wanru instructed from the side.

Xiaoman was in a deep coma, and to avoid sinking to the bottom of the medicine barrel, she had to stand on a springboard and be held up with both hands.

Time ticked by, and Li Tianyi was starting to feel the strain.

"Brother Tian, ​​hang in there, just a little longer!" Su Wanruo frowned deeply. "My little sister will wake up in half an hour at most!"

"Drink! Ha!"

Li Tianyi carried his younger sister with all his might, gritting his teeth and persevering.

I was drenched in sweat after ten minutes.

After 20 minutes, both arms had lost sensation.

At the 28-minute mark, I saw double vision, my whole body trembled, and I was on the verge of collapse.

Suddenly, Xiaoman opened her eyes.

"Little sister, hold on!" Su Wanruo immediately pulled the rope. "Brother Tian, ​​don't fall asleep!"

Li Tianyi suddenly woke up and cooperated with her.

After some effort, he emerged safely from the ten-meter-long barrel, but lay on the ground, unable to lift a single ounce of strength.

Su Wanruo was also very tired, but she dared not rest and kept throwing things into the medicine bucket.

Xiaoman didn't recognize what it was until the pumpkin appeared, at which point she asked, "Sister-in-law, are you treating me like a soup pot?"

"Shut up!" Su Wanru glared at him. "Climb to the first springboard, sit cross-legged, and repeat after me: 'If the heart is pure as ice, one will not be alarmed even if the sky collapses...'"

Soon, with the help of the Taoist calming mantra, Xiaoman successfully entered a meditative state.

Satisfied, Su Wanru stepped back and came to Li Tianyi's side, saying in a voice barely above a whisper, "Keep the water temperature at ninety degrees!"

Li Tianyi dragged his exhausted body open the door and used the system space to take away the five rolling iron pots.

Boiling water was poured into the bucket, and steam rose, completely enveloping Xiaoman.

"Watch the water level!" Su Wanruo used sign language.

Li Tianyi kept a close eye on the water level.

Ten minutes or so passed, and Xiaoman felt as if thousands of insects and ants were gnawing at her internal organs. She suddenly woke up, crying, "It hurts so much, it hurts so much..."

"Take her to the second springboard!" Su Wanru shouted.

Xiaoman was mentioned above.

"Lie flat on your back and silently recite the calming mantra I just taught you!"

Following the advice, the intense itching gradually disappeared...

The following day, the ten-meter-long tub was completely filled with water, and Xiaoman soaked in the tenth compartment, her head resting on the edge of the tub, her complexion rosy and full of vitality.

"Brother Tian, ​​you go and rest. I'll take care of the rest of the time!" Su Wanruo had been busy lately and wasn't in as good shape as him.

"You go and rest, I'll take care of it!" Li Tianyi forced himself to stay alert.

Seeing that he was unwilling to leave, Su Wanruo could only go to rest first. Standing outside the door, she said, "Every half hour, throw down one of the items I asked you to prepare, in any order."

"OK!"

Over the course of nearly seven hours, Li Tianyi threw in the following ingredients: licorice, angelica, ginseng, atractylodes macrocephala, eucommia ulmoides, cordyceps sinensis, lingzhi mushroom, loquat leaf, corn, pumpkin, sweet potato, mung bean, and apple flesh.

As soon as the apple flesh sank to the bottom of the bucket, the medicine surface shimmered with a golden glow, accompanied by a faint 'humming' sound.

Su Wanruo immediately made her move, precisely inserting the golden needle into Xiaoman's acupoint.

"Using golden needles to acupoints, opening the Ren meridian!"

The golden light shone brightly, and the sound of acupoints being broken could be heard continuously emanating from Xiaoman's body.

"Nine turns of the golden needle, open the Du meridian!" Su Wanruo focused intently as she inserted the last needle, "Merge!"

Click, click...

Xiaoman's meridians were completely unblocked, making her look like a fairy, pure and ethereal, untouched by worldly dust.

Su Wanruo fell straight down with a smile on her lips.

Li Tianyi quickly helped her up, pinching her philtrum and the space between her thumb and forefinger, "Wanruo, Wanruo!"
