Astral Cockroach

On a planet with zero technological advancement, apart from raw stone mines, other underground mineral veins remained largely untouched.

Last year, from early September to the end of November, King Rat roamed the Jinping Mountains with seven bamboo rat warriors, searching for God-given seeds while also looking for raw stone mines.

Having just familiarized themselves with the environment, they didn't find any God-given seeds or raw stone mines, but they did happen to remember several peaks with relatively high metallic element content.

Banbu couldn't wait to set off, personally exploring and inspecting each one.

Most were not mineral veins, but merely soil and rocks containing relatively rich metallic elements.

Finally, he located a small-scale limonite deposit, with mediocre ore quality and iron content of less than 50%.

After a dozen or so trips back and forth, he transported about 2 tons of ore.

This time, it was still for experimenting with the metallic abilities corresponding to the divine inscription patterns. There weren't any extra raw stones, so the demand for iron was low. The metal divine ability could directly convert non-metallic impurities into metallic elements, and the purity requirement wasn't too high, so Banbu simply made some charcoal blocks and didn't bother building a blast furnace or looking for limestone.

...

Among all the God-given seeds, the Bloodthorn God-given seed appeared the most adorable and obedient, and it had the strongest ability to absorb and release Origin Power, making it the best choice.

Banbu took out 20,000 raw stones, and Big Head commanded the ant colony to grind them all into powder in one go and throw it in.

The Bloodthorn God-given seed quickly absorbed the overflowing Origin Power, and at the same time, fed it back into Banbu's body.

Banbu controlled it, injecting all this Origin Power into the heart's divine inscription pattern.

The whole process lasted for almost half a day. After absorbing enough Origin Power, the previous divine inscription pattern was lit up and activated again.

Banbu ate and drank his fill, rested until late at night, and then, with Big Head and the seven bamboo rat warriors, came to the water intake of the mountain top reservoir.

The alloy pot that cost 20,000 raw stones to make last time came in handy—renamed the experimental "crucible".

The limonite was pre-cut into small particles by the bamboo rat warriors, and the charcoal blocks were also ground into powder. The two were thoroughly mixed.

Taking a portion, he put it into the pot.

Banbu locked onto the pot, opened his mouth, and a pillar of fire spewed out, continuously, another pillar of fire spewed out.

Two pillars of fire, ultra-high flames directly melted the ore particles.

The carbon reduced the iron oxide to pure iron.

Ignoring the rapidly flashing light of the carapace Origin Power patterns, Banbu's mind turned, and he immediately activated his divine ability: manipulating the molten iron to separate from the impurities, forming a metal iron ball next to it.

"Success!"

"Good purity!"

"I'll precisely control it later and use my divine ability to create some chromium and nickel elements, which can be fused into stainless steel."

Banbu was very satisfied.

The seven bamboo rat warriors watched with wide eyes, amazed, they could feel that the iron ball refined by Banbu contained almost only the single iron element.

King Rat asked, "Banbu, what are chromium and nickel?"

Banbu said, "They are all metallic elements, slightly better than iron."

King Rat asked again, "What is stainless steel?"

Banbu explained, "A mixture of various metallic elements, forming a high-quality metal material with corrosion resistance, high temperature resistance, high toughness, and hardness."

Big Head didn't have so many questions, commanding the worker ants to bring Banbu beast meat and Origin Power food to replenish the physical strength and Origin Power consumed by releasing the flame ability just now.

When Banbu recovered, the iron pot had almost cooled down.

Bai Zhu stepped forward, scraped off the slag in the pot, and added new material.

Repeating the same trick, he continued to refine the second metal iron ball.

...

The refining work didn't go very smoothly. Each release of the flame ability required a considerable amount of time to recover. Banbu was busy on the mountaintop all night, plus a whole day, before finally refining 50 iron balls.

Each one weighed about 20 kilograms, for a total of 1 ton of pure iron.

At this time, the light of the divine inscription pattern at Banbu's heart also dimmed a little. After careful sensing and calculation, it consumed about 5,000 raw stones of Origin Power.

Putting 5 iron balls into the iron pot together, he spewed out two consecutive breaths of flame, melting them.

Activating his divine ability, he manipulated the molten iron to flow out of the pot, forming a straight hollow pipe, with a relatively large filter head at the top, automatically extending towards the inside of the mountain top reservoir.

The amount of material was just right, the filter head touched the bottom of the reservoir, and the pipe extended about 2 meters out of the cave.

Resting and recovering, he then created the second pipe.

Due to the limited materials and Banbu's limited divine abilities, the pipe was designed to be only 2.5 centimeters in diameter, and the pipe wall was very thin. Saving materials, the second pipe extended 15 meters down the mountain.

Carrying the crucible, he moved down the mountain.

Banbu ate and recovered, and then continued to use his divine ability to create pipes.

...

He worked until noon the next day, and the last section of pipe was created. Finally, he carefully designed a faucet and a metal base to fix the faucet.

"This is the switch."

"Up is open, opening it will release water."

"Conversely, down is to turn off the water."

Banbu explained simply, turned off the faucet, and took Big Head and the seven up the mountain.

Now, the pipeline is divided into two sections. The first section is the first section coming out of the dark reservoir; the second section leads down the mountain, about 120 meters long, connecting the water faucet.

The latest novel is first published on the 69 Book Bar!!

Banbu asked Big Head to command the ant colony to fetch water with bamboo tubes and pour water into the second section of the pipeline.

Finally, he used the little remaining divine ability to manipulate the metal, perfectly connecting the two sections of the pipeline.

Returning to the faucet location at the foot of the mountain, he opened the faucet, and there was a "glug glug" sound, followed by a "哗啦啦" continuous flow of water.

Pulling the handle down, the switch closed, and the water flow stopped.

Lifting it up, the switch opened, and the "哗啦啦" water continued to flow.

"Wow!" Big Head exclaimed, shouting, "Banbu, you are amazing!"

Banbu was secretly proud, keeping his mental power calm, and instructed, "Big Head, from now on, fetch water here, saving the 120-meter climb up the mountain, and also saving the trouble of entering the dark reservoir to fetch water."

"I understand!" Big Head was overjoyed, eager to try.

Banbu waved his antennae and said, "Big Head, you try it."

Big Head stepped forward, stretched out his forelimbs, opened, closed, opened, closed, trying repeatedly, like a child getting a new toy, constantly cheering "Wow wow wow".

The seven bamboo rat warriors all watched curiously. After Big Head had enough fun, King Rat took the lead, and they tried it in turn, marveling and praising Banbu.

How did the water come out of the reservoir by itself? Unintelligible.

Magical!

...

From then on, Lizhu Peak used tap water.

And it was the most expensive water supply project in the entire universe. Calculated, including the crucible, the 120-meter pipeline cost more than 40,000 raw stones!

The supreme skill of a Dominator realm, used to make tap water pipes. If that fallen Dominator realm expert knew, he would definitely be angered to death, right?

Banbu was also helpless. Restricted by his current strength and financial resources, he could only display this basic skill.

Continuously releasing flame abilities and precisely manipulating and using divine abilities, Banbu was mentally exhausted. He returned to the cave, lay down on the ground, and fell directly into a deep sleep.

...

"Banbu, Banbu..."

Just as he fell asleep, before his sweet dreams could begin, Big Head's shouts rang out outside the cave.

"What's wrong?" Banbu's heart sank, and he asked, "The faucet wasn't broken by you guys, was it? My divine power is used up, and I don't have any extra raw stones. I can't fix it."

"No, no, it's good news." Big Head said, "Wind Chime told me that a little warrior was just born in its territory."

Big Head also said angrily, "Banbu, have you noticed that Wind Chime has been busy on the mountain all morning? It shoveled off all the wind chime flowers it planted. I remember, it used to want to lure Red Rice and Firethorn to plant wind chime flowers with it. Too bad!"

"Shoveled them all..." Banbu's antennae twitched, and he murmured, "It seems that the little warrior was just born this morning. This guy is ruthless enough!"

Banbu also comforted, "Big Head, Wind Chime's soul is injured, and it's not young. It must advance to Mountain Lord in the next few years, and it may fail... It wants to train its own direct descendant, and it has saved some possessions, probably to pass them on."

Big Head was a little flustered when he heard this, and asked, "Fail... Banbu, what if it fails?"

"What else can we do? I'll burn the corpse with a fire..." Banbu sighed, "Wind Chime's promotion to Mountain Lord is not very dangerous, we don't need to worry too much, the key is that Wind Chime itself is afraid. I'm very tired, I'll rest first, and go see it after I wake up."

"By the way, Big Head, you keep an eye on them and don't let them play with the faucet randomly. That thing is not strong, and it's really unrepairable if it's broken."

PS: Currently have 8 chapters in reserve, working hard, probably can explode with 10 updates tomorrow.
