"Zhou Xiaohu's people have been here?" Zhang Yiheng's eyes swept over Xiaoqi's emaciated body, and when he saw that it was fine, he was completely relieved.

"Don't look at whose sister I am, they were scared back by me, hehe!" Xiao Qi patted the shiny firewood knife pinned to his waist.

The tone was light, but there was a hint of nervousness in his eyes.

In the end, she is just a sixteen-year-old sister-in-law, facing jackals, tigers and leopards alone, and her heart is inevitably a little empty.

Zhang Yiheng rubbed Xiaoqi's dry and messy hair distressedly, and said, "Go to sleep!" Brother, I'll call you to dinner. ”

It is a luxury to want to sleep peacefully in the border camp.

Without the shackles of law and morality, stealing, robbing, killing... It's all tacit consent.

It's not too common to wake up in one fell asleep.

Xiaoqi obediently lay on the bamboo mat, holding the plush doll of the pink long-eared rabbit, and soon fell asleep.

Zhang Yiheng checked around, fixed the wooden door, sat down at the desk, and took out a palm-sized, shiny card from his arms and inserted it into the base of the energy lamp.

Flickering a few times, a dazzling white light illuminated a corner of the room, and a set of red light numbers on the base lit up.

47 degrees!

It can be used for 14 days! Zhang Yiheng was thinking in his heart, a little distressed, this 100 degree first-order energy star card only used half a month to have less than half of the energy left.

According to the past living habits, a 100-degree energy star card should be able to be used for about thirty-eight days.

Recently, it's been a lot more common than usual!

It's easy to go from thrift to luxury, and it's hard to go from luxury to thrift, well! Be vigilant.

Thinking of this, Zhang Yiheng adjusted the energy lamp to the brightness of the table where he could only see it, and then reached out and took out the bottles and cans in his arms.

The strange environment of the Jiuzhou Continent has created countless dangerous races, and it has also given birth to strange human civilizations.

Human beings can survive in such a harsh environment and dominate the environment, and they also have special abilities that they rely on.

After thousands of years of development, human beings have relied on their ingenuity to create a weapon...... Star Card!

And Zhang Yiheng is a card maker.

"The last time the pen was obviously smooth, why did the energy regression?" Zhang Yiheng frowned and thought for a while.

"Could it be that the middle overhead structure affects the energy return at the back?"

"Or is the Erduan Chisel Xin knife carving method not suitable for the Richie style knot?"

After thinking about it, Zhang Yiheng was a little unsure, "Let's go into the card house and take a look!" ”

Focusing his spiritual power on the sea of knowledge, Zhang Yiheng's consciousness was like encountering a dark whirlpool, and he was sucked into it at once. After a period of dizziness, a pitch-black space of dozens of square meters appeared in the sea of knowledge.

This is Zhang Yiheng's biggest secret, and it is also the hole card he relies on to survive.

【Super God Card House】!!

The pitch-black space is square, surrounded by bookshelves against the wall, a total of four bookshelves

On one side, the shelves are full of hundreds of books.

The bookshelves on the other three walls, although there are also books on display, are filled with a faint layer of white mist, which cannot be seen clearly.

In addition to the bookshelves against the wall around the perimeter, there is an antique desk in the center of the whole space.

Above the desk, a small lamp glows in the upper right corner.

The light is very small, just like the energy lamp on the desk outside, which can only ensure the recognition of things.

Zhang Yiheng glared at the small table lamp, as if he had seen the thief who stole his five million alliance coins, and his eyes were full of resentment.

Zhang Yiheng didn't know when this space began to appear, anyway, when he had a memory, it was there.

The bookshelves that can be touched by the wall are full of knowledge about card making.

Over the years, Zhang Yiheng has relied on these books to complete the introduction of card makers.

The most magical thing in the space of tens of meters is the small table lamp that he loves and hates.

As long as the lamp is lit, his body will change dramatically, his concentration will be a hundred times greater, his mental power will skyrocket, and his control over every inch of his body will be extremely precise.

The rules of time and space seem to be distorted in that moment, everything in the world slows down, and the distant scene seems to be close at hand.

It's just that there is no free lunch in the world, although the table lamp is good, it burns money to use!

A first-order energy card with 100 degrees of energy can only support its fully open state for five minutes.

The faint light that can only barely read can only be used for two days.

Absolute gold-eating behemoth!

He loved and hated this lamp, and his heart was mixed.

"I remember that this problem seems to have been mentioned in the book "Slow Fitting Liquids"." Zhang Yiheng walked quickly to the middle bookshelf and quickly found a reference book with a thickness of ten centimeters.

In the super-god card room, there is no such thing as reading books quietly.

In order to save time and burn less energy, he always reads books in a hurry, forcibly writes them down, and returns to reality to digest them slowly.

In ten years, 1,700 first-order energy star cards and 170,000 alliance coins were consumed, which was enough to exchange for a place to live in the city.

"It turns out that because of the aging of the melting, the middle section of the nine-point star ink has the best effect, and taking it early and late will affect the energy flow." Zhang Yiheng was stunned.

After solving the problem, he quickly exited the [Super God Card House].

Although he turned on the small lamp, his card-making speed and success rate would be greatly improved, but the money burned by the lamp was enough to erase all his earnings.

Take out a palette-like porcelain dish from the workbench and pour out the raw materials in the bottles and cans in turn.

The first-order energy star card, the most basic card, but the process is the same.

Raw material processing, melt blending, structure delineation, engraving sculpture, energy, charging.

He has repeated these tasks tens of thousands of times, and he has long understood them.

Nine-Minute Star Ink, the melting liquid formula he was most familiar with, could make the energy in the first-order energy star card reach one hundred and four degrees.

The point is, the cost has not increased!

Don't underestimate the value of these four degrees of energy,

After thousands of years of development, the basic system of the card-making industry has been finalized, as the most widely used, the highest frequency of use, the largest use of the first-order energy star card, its production cost has been studied by countless generations, has long been pressed to the minimum.

To this end, a universally agreed standard has been formed in the card manufacturing industry:

One kilowatt-hour of energy is equal to one alliance coin.

Without increasing the cost, just by relying on the innovation of liquid preparation, the first-order energy star card can be increased by four degrees, which is enough to cause a huge wave in the card making industry if it is transmitted.

"Uncle Niu should be able to arrive today, there are still ten first-order energy star cards left, let's go!"

Thinking that he would be able to get the last material needed for the first magic card in his life [Heart Piercing Cane] later, his heart was full of energy.

"And Zhou Xiaohu, people are really forgetful." A chill flashed in Zhang Yiheng's eyes.

Gathering his mind, Zhang Yiheng focused his attention on the present.

The melt pen sucked in the pale green melt liquid, fixed the main board of the energy star card, Zhang Yiheng put down the pen quickly, he has been using this structure for a year, and it can't be cooked.

In the small room, Xiao Qi slept soundly with a long-eared rabbit doll on his side, his small mouth slightly upturned, as if he was dreaming of something good.

The walls of the room flickered, and the faint light set off the boy's back greatly.
