"Good master!" According to Chen Lu's request, the price of one gram of black mud is 50 million, and it is still in short supply.

Because the system still regards black mud as the most cost-effective thing.

However, when fifty grams of black mud were sold, Chen Lu's energy needed was still nearly two-thirds short.

Chen Lu is also distressed, but there is no way, since you want to do it, you have to be the best.

Gritted his teeth: "Sell, directly add another hundred grams, and when I buy what I need, I will buy all the black mud cultivation utensils for the rest!"

"Haole!" Xiaoyao happily agreed, and immediately put 100 grams on the shelves, with a direct price of 7 billion energy.

This time it's not the best value for money.

But it was still taken away.

harvested 4.9 billion, and immediately bought the two books of heaven and earth change and control that Chen Lu needed.

In this way, there are still more than a billion left, and Xiaoyao didn't tell Chen Lu that it had raised the price, but Chen Lu saw the change in his energy at a glance.

Seeing that the energy that was originally close to 1.7 billion was instantly only 100 million, Chen Lu was also secretly amused.

But he didn't say anything, Xiaoyao thought he was doing well and doing it fast, and he was still complacent.

A black ball bounced around on the screen of the chief engineer's room, which was the expression of Xiaoyao's happiness.

The reason why Chen Lu was so generous and let Xiao Yao spend so much energy to buy utensils in one go was because she knew that these things would be hers sooner or later.

More than a billion vessels directly tripled the expansion of the cultivation room.

After Xiaoyao was excited, he immediately began to arrange cultivation.

Anyone and intelligence can foresee that the next harvest, the black mud will be three times the original.

In this way, the black mud spent today will only take more than two months to earn back, and there are many more.

Thinking of this, Xiao Yao jumped again, and let out a weird laugh.

That kind of mechanical voice made Chen Lu feel terrified.

The goosebumps fell all over the place.

I want to plug its mouth immediately, but I can't find a way.

Helplessly, Chen Lu had no choice but to interrupt it with a book: "Xiao Yao, come and help me take a look, how can these things be cultivated?"

Hearing Chen Lu's voice, Xiao Yao really stopped the terrifying laughter.

Tell Chen Lu: "Master, books have been transformed into existences that can be read and understood by the master according to the earth's environment."

You can learn on your own, just do it!"

"I know I have to do it, but what is this heaven and earth energy?"

"It's energy!" Xiao Yao said as a matter of course.

Chen Lu was a little stunned: "Is that energy?"

"Yes!"

Chen Lu, who got the answer, immediately turned into a Hedong lion:

"Oh my God, you spit out your energy for me!

"Uh... The goods have been sold and will not be returned, come on, master!"

How could it spit out something that was put in its mouth? Even if it wanted to, its hands would not allow it! Even though it had no hands.

Chen Lu also wanted to cry without tears, looking at the remaining 100 million energy, she didn't know where she could go?

"The master can go to the cultivation area under the colorful tree in the planting area, it is a device that collects the energy of the entire space, where all the energy will be gathered, it is very sufficient, it is conducive to the master's cultivation!"

"Colorful trees?" Chen Lu knew that there was such a place, the trees were very beautiful, and they didn't look like real things at all, so she hardly paid much attention to this thing.

I didn't expect it to be a machine that pools energy.

So without stopping, a teleportation came to the colorful tree.

It's really more comfortable here than anywhere else.

Chen Lu stretched his waist and made a lazy waist, thinking: No wonder energy is so precious, it turns out that it is good for the body!

Learn to sit cross-legged like others meditate on TV.

Chen Lu began to look at the changes in the world.

She can only open 7 pages of the book so far, and each page is a branch.

According to the introduction, it is necessary to integrate all seven branches in order to learn the following.

Therefore, the latter part was banned, and she didn't have the ability to see it for the time being.

The first page is water.

Water is the source of all things, so if you want to understand any change between heaven and earth, you must first understand water.

The generation, formation, form, and so on of water.

And it also contains all kinds of water.

For example, ice, snow, such as weak water, etc., are all branches of water.

You can learn it all here.

Although it is only a small piece of paper, the huge number of things recorded in it really subverts Chen Lu's worldview.

After a cursory look, Chen Lu began to meditate with his eyes closed according to the above introduction.

Want to look for water ions in the air.

Five minutes passed, Chen Lu's legs and feet began to be numb, and ten minutes passed, and his legs and feet were a little uncomfortable.

Half an hour has passed, and Chen Lu has lost the perception of her legs and feet.

Soon an hour passed, and Chen Lu still couldn't find any light in the darkness.

It's a little dizzy.

However, which Chinese person does not have a fairy dream?

Chen Lu is naturally no exception, so she is unwilling to give up.

What's more, there are unknown enemies eyeing her.

Continue meditating until two hours have passed, and at the end of the three hours there is still no gain.

After all, she is just an ordinary person, although her body has been optimized by black mud, but she has not even tried martial arts or anything like that.

If it weren't for a sense of hope and a heart that refused to admit defeat, she would never have persevered now.

But even after holding on for so long, she had to give up.

While shouting Xiaoyao, he began to stretch his muscles and bones.

The legs and feet have long been unconscious.

You can only rub it slowly with your hands.

After hearing Chen Lu's scream, Xiao Yao immediately shifted his attention from the cultivation room to her.

"What's the matter, master!"

As soon as the medicine came, Chen Lu began to cry:

"Xiaoyao, doesn't the book say that it is easy to learn? I have been meditating here for hours without discovering anything?"

"Uh...... I'll take a look!"

This doesn't matter, Sister Chen Lu is almost crying stupidly by herself, only to hear Xiaoyao say:

"Master, you haven't cleansed the marrow yet, how can you communicate with the elements of heaven and earth?"

"Is the sin of cooperating with me for three hours in vain?" Chen Lu wanted to cry without tears.

Also blame her, didn't look carefully.

Turn the whole book over, and you will see: if you want to practice this skill, you must first wash the marrow of the I Ching!

"I#~**##......" Chen Lu's mouth was fragrant.

I can't bear it.

However, after complaining, the cultivation had to continue.

Xiaoyao immediately found some elixirs from the exchange to wash the essence and cut the marrow to Chen Lu.

The first time Chen Lu received the pill was to check the instructions.

It says that this medicine must be taken for seven consecutive days before it can be effective.

Chen Lu was immediately dissatisfied, does this thing really have an effect?

Looking at his remaining energy, Chen Lu was full of black lines.

"Xiaoyao, you come out!"

"What's wrong, master?"

"Are you really called Xiaoyao? It's Xiaojiao, right? Let you buy a bottle of myelin cleansing pill, you actually only spent a hundred energy?"

"Are you dealing with me or are you lacking that energy?"

"Uh...... I'm sorry, I'm used to it!" Xiao Yao's voice was also a little low, obviously knowing that he had done something wrong.

"Get used to it, get used to it......" Chen Lu didn't know what to say about it, and it could still become a habit to buy things together and buy cheap ones?

"Don't tell me that the machines you bought me before and all the materials are the cheapest?"
