The red boy who came back from the Dragon Palace of the East China Sea was on Cuiyun Mountain, and carefully browsed the overall layout of the ditch dug by the little demons on Cuiyun Mountain.

Surrounded from the gate of the village to the back of the mountain, basically if it can be built, the goblins or immortals on the ground can drill into Cuiyun Mountain without any seams.

As for those goblins or immortals who are good at fighting in the sky, Cuiyun Mountain has thousands of bird guns, and even sniper guns waiting for them.

The calcium carbonate for refining cement will not arrive until at least in the evening, and the red boy still informs the red mink to start refining some of the steel needed for the building walls.

Collecting the clouds under his feet, the red boy soared into the air, and a small demon camp tumbled down to Cuiyun Mountain.

Most of the goblins in the little demon camp have gone to dig ditches, so they seem very deserted.

Only a few little demons are still helping the red mink by the wrought iron furnace.

Those who move iron, those who fan fire, those who serve water, those who quench 。。。。。。。

After the discussion between the red mink and the shrimp essence, the two had a special chemical reaction.

The erudition of shrimp essence has opened up a lot of new refining ideas for red mink.

At this time, I am trying, a new refining method to refine the parts needed for the sniper gun,

The fire of the furnace illuminated the red mink's face red, and the red mink's eyes were staring at the steel in the furnace with beads of sweat, and the red boy had come to his side, but he still didn't know it.

"Red Sable, don't refine anything new now, now Cuiyun Mountain plans to build a huge wall as a strong guarantee. This is where you need to refine some thick steel rods. ”

The red boy walked up to the red mink and said lightly.

The sudden appearance of the red child scared the red mink, but what the red child said was still clearly heard.

"Ahh

How many steel rods do you need? I can refine them first!" the red mink looked like he was obeying the red boy's orders.

"It's going to be a lot!!!, maybe all the ordinary steel stored in Cuiyun Mountain now has to be smelted. Each one is almost as wide as I am, and then I'll drop some little demons to come and help you, and you can't do it alone. ”

This steelmaking is almost a huge steelmaking process, and of course, the manpower required is definitely not less.

"No problem, as long as there is steel, this iron rod can still be refined by my red mink, young master Hong, please rest assured!"

After so many times of steel refining, the red mink has become more confident.

In steelmaking, there is a red mink, and in the red child, there is almost no sorrow.

This is thanks to his good uncle Ruyi Jin Xian.

。。。。。。。

In the evening, the mussel spirit came to Cuiyun Mountain with a large group of strong men from the East China Sea Dragon Palace carrying tens of thousands of catties of shells, which was only a small part of it.

"Fortunately, Brother Mussel Spirit, this is a blessing!"

After unloading all the goods, Red Boy and Mussel Jing started talking, and the two of them didn't know each other.

The red boy also took out more than 10,000 demon coins and gave them to the clam spirit as a blessing.

The current Cuiyun Mountain is really not short of money, and the operation of these days has already accumulated a lot of wealth for Cuiyun Mountain.

The demon coins placed in the back warehouse of Cuiyun Mountain just made them rust.

"Little Brother Hong, don't be too polite, this is what we should do, how can we pay back the money?"

The clam spirit reached out politely and took the 10,000 demon coins in the red boy's hand.

Everyone understands this rule, so let's excuse ourselves first and then accept it.

After receiving the money, the clam spirit led the little goblins back to the Dragon Palace of the East China Sea to prepare for the next wave of shells.

At this time, Black Whirlwind and Donkey Kong have not returned.

。。。。。。

In the palace of King Yurong.

Xiao King Kong's face was piercing, "No, it's cheaper for 1 demon coin!"

"Little King Kong, it's really not no, I've already bought it for you at the price of jumping off the building, and I've already given you a few dollars cheaper. It really can't be less!"

King Yu Rong and Xiao King Kong bargained all day, their mouths were dry, their lips were already chapped and peeling, and they still didn't win this business.

The last time Red Boy made a deal with him, the demon coins he earned had already been used up by him, and now is the time for lack of money.

Otherwise, he wouldn't have spent so much time going back and forth with Little King Kong.

But Little King Kong is really a tendon.

King Yu Rong gave him an average of dozens of demon coins, and Xiao King Kong still wanted to continue to be less.

Refuse to make a deal.

As for the black whirlwind, he is already an old slippery head, sitting on the side and watching the tiger fight, drinking the best tea, so comfortable.

"Little King Kong, if that's it, we've already made enough money, and Young Master Hong won't blame us for closing the deal at this price. "The black whirlwind is also tired of tea, and wants to return to Cuiyun Mountain, so he persuaded him.

"No, he has a lot of this demon coin, and my little King Kong will never let go!"

"You little demon!" Yu Rong stomped his feet angrily, "I really convinced you, I really deserve to be a goblin mixed with the red boy!

The sky has begun to darken, from the noon dispute to the price to now, Yu Rong Wang finally couldn't bear it anymore, and said loosely.

"Hahahaha, the young master said that as long as the skin is dead, the iron pestle can be sharpened into a needle!"

Xiao King Kong successfully saved at least tens of thousands of demon coins for Cuiyun Mountain.

He couldn't be proud, crossed his hands on his hips, and said a famous sentence that Red Boy once said in front of him.

"Harm! That is as long as there is perseverance, the iron pestle is sharpened into a needle!" the black whirlwind patted the black lines on his head and face.

"Hehe, whether it's dead or perseverance, anyway, today Yu Rong Wang, you have finally been ground into an embroidery needle by me!"

King Yu Rong was speechless for a while; "。。。。。。 ”

Next, Xiao King Kong and Yu Rong Wang signed the same post as the last time they signed with Red Boy.

The deal is finally done.

。。。。。。。

As night fell, the whole world went dark.

However, Cuiyun Mountain lacked bright lights, and in the night, the red children were summoned from the working demons.

I selected a few clever ones and opened a course on cement refining.

These clever little demons have all entered the academy for a period of time, and they have mastered the simple refining knowledge given to them by the red boy very quickly.

The red children had to admire their foresight in establishing the school at that time.

Knowledge is different, if you change to the goblins when you first came, I'm afraid that they may not be able to learn even if you try your best to teach them.

In the end, although the refining failed several times, the demons in the back slowly comprehended the refining skills.
