After this incident, Lin Jing can also determine the upper limit of his ability, as long as he has enough magic power, it is not difficult to build a city, as long as he cooperates with the magic array that manipulates earth and stone, the spiritual power consumed is also very small.

This experiment also made Lin Jing very happy, but she didn't plan to build a giant city in her tribe.

First, because of the small population of his Yanhuang Division, the part that has been built now is enough for the entire tribe to live, and there is still a lot of vacancy, and secondly, because the tribesmen's ability to operate independently is cultivated as much as possible, which is the development mode of Jiankang.

Although the Birdmen easily obtained such a city, they did not participate in the construction of it themselves, and they did not know how to build such a building at all, and even quickly accepted such a 'gift'.

Lin Jing's things are not so easy to take, but these birdmen don't know that the lifeblood magic crystal that maintains them living on the floating island is already firmly in Lin Jing's hands, as long as Lin Jing is willing, he can destroy this floating island at any time, and any sky city will become a thing of the past.

The premise is that these birdmen don't come to provoke her.

Holding a piece of soap as white as mutton fat in his hand, he gently rubbed it on his skin.

With the Separation Magic Item, the alkali in the grass ash can be separated, and the soap made is no longer the original black and gray color.

Not only that, but the soap is also filled with incense powder extracted from potion residues, giving the soap a faint fragrance.

This soap is now only used by a few people such as Lin Jing, and it has not yet been promoted, just waiting for a suitable time.

As soon as the half-month training day is over, it is time to issue currency.

Early in the morning, Lin Jing and the hundreds of birdmen she had cultivated began to get busy, and Lin Jing asked people to move out boxes of gold, silver, and copper coins.

These so-called gold, silver and copper are not the kind on earth, but are directly separated from minerals containing metals, but the color is similar to gold, silver and copper.

In order to separate these metals, Lin Jing also specially arranged a large separation magic array with magic crystals, and now her magic crystals are sufficient, since the floating islands have been merged, only the largest magic crystal is needed to maintain the entire merged floating island floating in the air, and the magic power used is less than one-fifth of the magic power it generates by itself every day, and the excess magic power will be stored for other purposes.

Therefore, those magic crystals that originally belonged to the small floating islands were all taken by Lin Jing as owned, there were more than a dozen of them, and the smallest one exceeded the green magic crystal in the clan.

Lin Jing had already thought that when he returned to the clan, he would immediately replace the green magic crystal with the magic crystal in his hand and return the green magic crystal to Sha Zhuzhu.

It's not what she wants if she doesn't pay it back, and now that she is rich, she naturally has to return it quickly.

There are many metal ores in the primitive world, and almost no one mines them.

Lin Jing couldn't tell which ores contained metals, they were all sent by people, and then thrown into the separation magic array to find them by luck.

Fortunately, in the end, the hard work paid off, and Lin Jing finally found many kinds of metal ores, separated as many as a dozen types of metals, and used these dozen to synthesize three colors of metals to make currency.

"Little sister, you're here!"

Silverwind strode over.

"Brother" Lin Jing shouted, and then chuckled, "You don't hatch eggs at home with Qiu Ying, what are you doing running out?" ”

She couldn't help laughing, because it was really funny, since the eldest brother gave birth to an egg with Qiu Ying, the young couple nested at home every day to hatch eggs.

If this is changed to birds, it would be forgotten, but when I think of a big man who is five big and three thick, holding an egg and incubating it in the nest, the picture is funny when I think about it.

Yinfeng was immediately embarrassed when he saw his little sister laughing.

"Little sister, don't laugh at me, you don't know how boring I am during this time, I hold my eggs every day, you see that I have lost weight"

Silver Wind pulled off the skin on his face that had lost a lot of weight.

"What are you unhappy about, people are what you are looking for, eggs are born by you and others, all of them are of your own volition"

Lin Jing said this, a little lucky, glad that she didn't have a child with Yao so early, and she wasn't ready to be a mother.

"Alas! I don't want to have children so early, who knows that there will be one"

Silver Wind is very depressed, he has done it with other women before, but he has not been pregnant, why did he have it all at once this time, okay, Qiu Ying is the woman he really likes, give birth to it, it would be better if it could be reborn later.

Lin Jing suddenly realized after hearing this, it turned out that this was the case, I didn't think of this reason before, it seems that the eldest brother didn't want to have a child so early, but because he didn't take precautions, he won the lottery at once.

"Maybe I'll make a birth control pill or something, it's going to sell well."

Lin Jing whispered, and thought of a good idea to make money, and her witch ancestors came up with a magic potion for contraception, this magic potion has no side effects, and it is an all-natural product.

"Little sister, what are you talking about? What birth control pills? ”

Silverwind heard the little sister's whisper.

"The birth control pill is a kind of medicine to prevent pregnancy, by the way, you still have Qiu Ying now" Lin Jing said very quietly, and looked left and right.

"Which one is that?" Silverwind didn't understand.

"It is"

Lin Jing quickly explained.

Yinfeng understood this time, and shook his head again and again, "No, I haven't slept with her since Qiu Ying gave birth to eggs, if there are a few more, then how can I be busy?"

"But little sister, does the contraceptive pill you just said really work" Yinfeng looked surprised, if he could prevent pregnancy, he wouldn't have to work so hard.

Lin Jing looked at Yinfeng cautiously, and nodded lightly, "Yes, yes, but I haven't figured it out yet, I'll tell you when I get it out later, I'm going to be busy now, if you have nothing to do, you can go with me to see it" I wasn't in a hurry to get birth control pills at all, thinking that my eldest brother and Qiu Ying would have a few more.

"Okay, I'll go and see" Silverwind was curious, he still had a childlike heart, full of curiosity about new things, and it was these shiny coins that attracted him here.

Lin Jing walked out of the palace with the silver wind.

The city is very busy today, with several stores opening and selling goods all over the city.

A few young birdmen were talking, "Why is it so lively today?" What are those people doing together? ”

"I don't know, let's go and see"

The curious young birdman walked over.

There is no advertising, not even advertising paper, there is no written inheritance of the birdmen, only simple patterns express some simple information, and modern propaganda methods are not applicable here.

However, Lin Jing also had a way to spread the elimination to all parts of the city.

I saw a flock of birdmen flapping their wings and calling in the air. (To be continued.) )
