After all the hardware facilities were basically installed, Lin Feng began the final debugging work.
The first thing he tested was the water supply system.
As the stream water was filtered through the sedimentation tank and flowed into the designated water storage area through the ceramic pipes, Lin Feng carefully inspected every connection to ensure there were no serious leaks.
Then there's the heating system.
He started a fire in the furnace beneath the "iron boiler".
He shoveled large amounts of coal into the furnace.
As the flames rise, the temperature inside the furnace gradually increases.
Lin Feng kept a close eye on the ceramic boiler and the heating ceramic tubes connected to it.
This is the most problematic part of the entire system, as pottery is not as durable as metal.
Fortunately, the pottery he fired was of fairly good quality.
Under the intense heat, both the boiler and the ceramic tubes remained stable, showing no signs of cracking.
About two hours later, when he put his hand near the outlet of the ceramic pipe at the bottom of the pool, he could clearly feel the warm water flowing out.
"It's a success!"
Lin Feng was overjoyed. Although the heating efficiency was far inferior to modern equipment, achieving such results under these primitive conditions was nothing short of a miracle.
Next was the testing of the sauna room.
He also started a roaring fire in the combustion chamber under the heating platform, scorching the volcanic rocks piled up on the platform.
These volcanic rocks are extraordinary; he collected them with great difficulty.
Among these stones are volcanic rocks, rich in minerals, which can promote sweating.
Furthermore, jade can have antibacterial properties and improve sleep.
After the stones were heated until they were red-hot, he scooped up a ladle of cold water with a wooden ladle and splashed it onto the stones.
"Sizzle!"
With a loud bang, a large amount of scorching steam gushed out instantly, quickly filling the entire small sauna room.
The scorching heat and humidity hit him in the face, causing Lin Feng, who was standing at the door, to take a step back.
He nodded in satisfaction. The amount and temperature of steam produced met his expectations.
Over the next few days, Lin Feng repeatedly debugged and fine-tuned the entire system.
For example, adjusting the size of the ventilation openings in the furnace can control the firepower.
For example, a small ventilation window that can be opened from the inside was added to the sauna room to adjust the steam when it is too concentrated.
He also directed the women to thoroughly clean the entire "bathhouse" inside and out.
The floor was repeatedly wiped with clean water, and the dust on the walls was carefully brushed away.
The inside of the hot spring pool was polished to a shine with clean animal hides.
Everything is ready.
Lin Feng chose a sunny afternoon as the first day of use for his "private hot spring".
He had the women boil plenty of hot water in advance and fill the soaking tub.
They then added the finest coal to the heating platform in the sauna, heating the stones until they were scorching hot.
After doing all this, he waved for all the women to leave and strictly ordered that no one should come within fifty paces of the "hot spring" until he came out.
The women naturally nodded and withdrew.
They gazed at the mysterious building from afar, their hearts filled with a complex mix of emotions.
Envy, disappointment, curiosity, and a hint of... grievance that was barely perceptible.
They put in so much sweat and hard work, yet they didn't even have the chance to see what was actually going on inside.
Lin Feng walked alone into his "hot spring".
He first went to the changing area, took off his slightly rough animal skin clothes, and put on a simple bathrobe he made of soft linen fibers.
Then, he walked into the steamy hot spring area.
The huge hot tub was filled with clear hot water, with wisps of white steam rising from the surface. He tested the water temperature; it was just right.
Lin Feng slowly stepped into the water, and the warm pool water instantly enveloped his body, dispelling all the chill and fatigue.
He sighed contentedly, immersing his entire body in the water, leaving only his head above water.
"This is what life is all about..."
He closed his eyes, feeling his muscles relax and his pores open, and his heart was filled with an unprecedented sense of satisfaction.
Lin Feng soaked comfortably in the hot tub for a long time until he started to sweat slightly. Then he got up, put on a bathrobe, and went into the sauna next door.
The sauna room was already filled with thick steam, and the temperature was even higher than in the soaking tub.
He took a deep breath, feeling the warm, humid air rush into his lungs.
He sat down on a simple stool made of wooden strips, and soon sweat poured out of every pore on his body like rain.
That exhilarating feeling of being drenched in sweat was a long-lost experience for him.
After steaming for about fifteen minutes, feeling the stale air in his body being expelled with the sweat, Lin Feng stepped out of the sauna and entered the soaking pool again, washing off the sweat with warm water.
Finally, he arrived at the designated cold water soaking area—which was actually a small stone pool filled with only a small amount of cold stream water.
He scooped up cold water with a wooden ladle and poured it over himself from head to toe. The icy stimulation invigorated him, and his skin tightened instantly.
After completing this entire "bathing process," Lin Feng felt completely relaxed and refreshed, as if he had been reborn.
He changed into clean clothes and walked out of the "hot spring" with an air of nonchalance.
The sunlight shone on his refreshed face, which was damp with moisture, making him look exceptionally energetic.
He glanced at the women in the distance, who were craning their necks and staring longingly at him, and a barely perceptible sneer appeared on his lips.
Lin Feng ignored them and went straight back to his cabin.
There, he served delicious food in golden tableware and his newly brewed fruit wine.
This "hot spring pool," the culmination of countless efforts, became another exclusive private space for Lin Feng in this wilderness, symbolizing his supreme power and ultimate enjoyment of life.
In the days that followed, Lin Feng would go to his private hot spring at a fixed time almost every day to enjoy the warmth and cleanliness that was unique to him.
He often soaks in a hot water pool at just the right temperature for long periods of time, feeling every inch of his skin enveloped and permeated by the warm water, and all his fatigue and chill are dispelled.
He stepped into the steam-filled sauna, letting the scalding steam open up all the pores of his body, sweat pouring down, carrying away the dirt and stale air deep inside his body, experiencing that exhilarating detoxification sensation.
He would meticulously wash his body with his own homemade soap, which had a faint herbal scent, dry it with a soft linen towel, and then change into a clean and comfortable loose bathrobe, also made of linen. The whole process was full of ritual and an unapproachable sense of dignity.
The women could only take turns using the "second-hand hot water" after Lin Feng had finished enjoying himself, when the fire in the hot spring gradually went out, and the still-warm bathing wastewater was discharged downstream through the pre-set ceramic pipes to a designated area.
Even so, for them, this is already a huge improvement.
They would bring their own earthenware basins and wooden buckets and wait carefully near the drain.
When the warm water flows out, they quickly fill the containers, then find a sheltered corner and use this hard-won warm water to wash their bodies, which are already covered with dirt and sweat.
That feeling was completely different from Lin Feng's ultimate enjoyment in the hot spring, but compared to directly using the icy cold stream water, it was already a heavenly treatment.
They would cherish every drop of warm water, carefully wiping every inch of their skin, trying to wash away the unpleasant stickiness and odor.
Lin Feng saw all of this clearly, but he never said much.
He wanted these women to understand that their treatment depended entirely on his will and their "contributions".
He enjoyed this absolute sense of control, and the way they were so cautious and subservient to him.
