Brother Dog walked in front of the water supply pipe and gently tapped the gray matte pipe with his bone joints, and the pipe responded with a dull "dong dong" sound.

Although Brother Dog does not have a forging level certificate, he has also helped a lot as Ah Yue's deputy, and his eye for metal has also improved.

The dog's paws kept rubbing against the pipe, and the silver was iron at a glance, but it was slightly darker than pure iron, and it was obviously alloyed by adding other metals.

It was built during the day and into the afternoon, and was directly sunlit for more than eight hours, and the surface did not feel any warmth, and it was still cool. Moreover, the surface of the alloy is not as smooth and flat as other metals, and there are many small protrusions when you look closely, and there is a frosted feeling when you start it.

Brother Dog no longer doubts what Chasing Wind said, all the ore smelting work in Tazhai Star is done by the blacksmith shop, and the forging technology is also headed by Ah Yue, so there is no alloy that even Brother Dog has never seen. But the unknown alloy in front of him just appeared, and even Brother Dog couldn't tell what metal was mixed in. The important thing is that this metal is stable and does not absorb heat.

Looking at the workmanship of the pipeline, every 100 meters, there will be two iron tongs like something deep into the ground, firmly fixing the position of the pipeline.

The entire water line is thoughtful and safe.

Brother Dog pedaled all the way to the pressurization station at the crash site of the spacecraft, and the pressurized station was surrounded by barbed wire, eliminating the possibility of destruction.

Further onto the edge of the ice lake, the pump is also very well protected, and Brother Dog also sees the ice lake covered with ice floes.

Brother Dog took a closer look at the entire water conservancy facilities, and had to sigh at the industrious wisdom of these aborigines.

More than a dozen kilometers of water pipelines also dared to think, and they really made them.

Just when Brother Dog was engrossed in understanding the water supply pipeline that connected the Niuyuke, the fish people of the Ice Lake began to test again.

The morning battle had lost a lot of its kind, and the pig-headed men were so powerful that the Winter Fury Fishmen felt a sense of fear for the first time.

It wasn't until the afternoon that the fish-man regained his curiosity and approached the shore to see if there was still danger, and when he came to the shore, he found a pump and a behemoth.

The Winter Fury Fishmen don't know what it is, but their body's powerful sense of water allows them to discover that this "abyssal mouth"-like thing is constantly devouring the lake they depend on for survival.

Realizing the crisis, the Winter Fury Fishman immediately began to organize the fishermen and came to the pump again.

Wait until the fish-man peeks out from under the water, and then looks at the shore with a confused look. It had only been half a day, and the shore they knew had disappeared, replaced by solid fortifications and a standing statue of "long-haired earth rammer".

Although he didn't know what was in front of him, it didn't stop the grumpy Winter Fury Fishman from attacking.

They are afraid of pig-headed people, but that doesn't mean they're afraid of dead things in front of them.

The stone and the spear pierced the rammer fiercely, but found that the spear broke off the stone and bounced back, and there was no way to cause damage, and there were many sharp wires on the surface, so there was no way to move at all.

Just as the Winter Fury Fishman was furious, a dog standing by the embankment caught the fishman's attention.

Can't cure buildings, can't you cure a dog?

The Winter Fury Fishmen bypassed the fortifications and rushed towards the dog brother "Waaaaa" who was on a field trip.

Brother Dog has completely believed what Chasing Wind said at this moment, there is no trace of welding in the entire pipeline, from the beginning to the end except for the separation when passing through the pressurization station, there is no decoration in other places.

This kind of technology is extremely simple for advanced civilizations, but it is very unreasonable for this kind of thing to appear on a planet where industry has just started in Tazhai. More than ten kilometers of pipelines without any welding points, one-time casting process, the pipeline has almost no impurities except for alloys, this purification technology and pipe gallery project if thrown to Ah Yue, it is estimated that the head will blow up and can not think of a good way, can only use the most clumsy casting and welding technology, it takes several months to complete.

When Brother Dog was immersed in how to explain to Ah Yue, the fishman suddenly screamed and scolded on the embankment not far away, and when he raised his eyes, he saw a piece of fishman holding a spear and running wildly, and the posture was eager to devour it alive.

Brother Dog was slightly stunned, and then immediately ran wildly, pedaling the bicycle and running.

At night, Brother Dog returned to the blacksmith shop in a mess.

Ah Yue was lying on the rocking chair, holding a teacup in her hand, her cheeks bulging as if she had stuffed two walnuts, and she was huffing.

The four big words "temporarily closed" at the door were particularly eye-catching in the firelight, and it seemed that it had not been open all day.

Brother Dog thought of more than 30 kinds of words to open the topic along the way, but he didn't know how to open his mouth at the moment.

"I went outside to see it today, and there was no trace of welding on the thirteen-kilometer-long water pipe from the new waist guest to the ice lake."

"It can't be!" Ah Yue slapped the teacup on the small table, and the tea in the cup splashed on the table.

Brother Dog ignored Ah Yue on his head and continued: "The surface of the water pipe is rough and grainy, does not absorb heat, and is mixed with an unknown metal in addition to iron, and the alloy is extremely stable. ”

Ah Yue rubbed up from the rocking chair and crossed her hands on her waist: "There are still metal elements in Tazhai Star that I don't know?" How can there be an alloy of metal that can't be smelted even on my side, it must be too dark at night. ”

"I watched it in the afternoon."

"And I learned from the aborigines that chasing the wind does activate the metal bioactive gene, and the pigs know this!"

At this moment, Ah Yue's face immediately couldn't hold back, her mouth opened and closed, she hesitated for a while, and her tone was not strong, and asked, "Are you sure?" He didn't even show it today before he was recognized......"

"They did go to erect the water pipes this morning, thirteen kilometers long, and it was probably very exhausting. Although I don't know the principle of this gene, I know that it will cost a pig-headed person to harness a gene close to lv2, carry dozens of tons of ore at full load, and smelt it into alloys. ”

Ah Yue was silent, it had been completely persuaded by Brother Dog, and admitted from the bottom of his heart that Chasing Feng had really gotten the gene.

"Then why didn't the boss speak from beginning to end, it's impossible for the boss not to know the power of this gene!"

So Ah Yue found Jiang Han with a question and asked him face to face.

Jiang Han didn't expect to make such a big oolong, but he immediately returned the pot to Ah Yue.

"Alas, Ah Yue, I'm very disappointed in you. It was you who handpicked Chasing Wind to become a blacksmith apprentice at the beginning, and I happened to get a fragment containing a metal bioactive gene, and I wasn't sure if I could really activate this rare gene, but considering that you cultivated Chasing Wind as a successor, I still chose to let him take a risk, but I didn't expect to activate the rare gene. I thought that you, as a special blacksmith, could see that he was different at a glance, but I didn't expect ......"

Ah Yue hurriedly straightened her waist and said stiffly: "I must have seen it!" It's just that I didn't expect the boss to be so powerful, and even this kind of gene can be obtained, so I came to verify and confirm it! ”

"Oh, I'll just say, how can you, a special blacksmith, not recognize you. Is there anything else, if I wasn't ready to rest, it would have been past 11 o'clock in the evening. ”

"It's gone, boss, you rest."

Ah Yue turned into a humble mouse, and the dog brother on the side pinched his mouth with both hands, for fear that he would laugh out loud on the spot and end up with a corpse on the spot.

Until the two left the Empire State Building one after another, Brother Dog couldn't help but laugh wildly with "ahhahahaha", his voice was wild and irrepressible, and then he was beaten up at the end.
