In the room, Chen Changan didn't care about other people's opinions, but he gave a simple explanation to Fang Yuan and a few people.

"My goal is to enter the Inner Courtyard, if I can't even solve these Outer Courtyard students, what qualifications do I have to enter the Inner Courtyard, what qualifications do I have to contact the vast cultivation world?"

Chen Changan's deep voice revealed a strong sense of confidence.

Fang Yuan and Li Yu looked at each other, both a little ashamed.

Although Chen Changan's qualifications are poor, his ambitions are very great, listen to him, Jinyang Academy is just a stepping stone to his rise.

Night.

Chen Changan continued to read the "Heavenly Hundred Thousand Souls Illustrated Book".

On the illustrated book, there is a large amount of graphic information, including the pharmacology and properties of each material, which is strange and complex.

Boom!Boom......

Chen Changan didn't say a word, and quickly flipped through the "Heavenly Hundred Thousand Souls Illustrated Book".

A few hours later.

Call~

Chen Changan took a long breath and put down the "Heavenly Hundred Thousand Souls Illustrated Guide", with a trace of excitement in his eyes.

After reading the "Heavenly Plateau Ten Thousand Souls Illustrated Guide", Chen Changan only felt that his knowledge had increased greatly, and some of the strange materials in the illustrated book were unheard of by him.

The effect of some legendary heaven and earth spirit objects has reached the point of almost going against the sky.

For example, Chen Changan saw a kind of "Xuantian Spirit Root", which could directly raise an ordinary spirit person to the limit of the spirit body, and even break through the limitations of the spirit body and reach another new life form.

There are also all kinds of strange heaven and earth spiritual objects, such as a kind of "sleeping grass", which can make people sleep for thousands of years and make their bodies immortal, or some kind of magical "blood" can allow human beings to have the blood power of those ancient races and even saints, and evolve into three heads and six arms, an immortal body......

In short, "The Illustrated Guide to Ten Thousand Souls in the Heavenly Plateau" brought Chen Changan into contact with a more vast and wonderful world, so much so that he had a feeling that the Jinyang Academy he was in now seemed to be just a small corner of the big stage of this world.

In the past two days, Chen Changan quickly analyzed the content of the "Tianyuan Wanling Illustrated Book", and had a preliminary understanding of the pharmacological application of these materials and their application in alchemy.

On this basis, he came to understand the "Basic Knowledge of Alchemy" and found that the principle was so simple.

As for the difficult "Fire Control Heart Formula", Chen Changan also understood a general idea, and the reason why he couldn't understand it thoroughly was mainly because this heart trick involved the practical application of medicine refining.

There was only one day left before he challenged the alternate Inner Courtyard student, and Chen Changan had the idea of wanting to improve his strength.

If he wants to improve his strength, it is very difficult for him, because he doesn't know where to start, he can't cultivate the exercises, and he can't absorb the power that is free from heaven and earth.

On second thought, it seems that there are only two ways, and they may not be successful.

The first way is to find some weapons with a strong heaven and earth power, and try to find a way to absorb them.

The second way is to climb the Tower of Babel again!

Chen Changan knew in his heart that with his current strength and realm, there was almost no hope of defeating Fu Jie.

At the eighth layer of the Mortal Realm, he had a great hope of winning.

Thinking of this, Chen Changan took out a Xuantie sword, which he bought outside, although it was not too valuable, but it cost most of his silver taels.

Chen Changan closed his eyes and carefully recalled the scene of absorbing the power of the plateau before.

Time passed bit by bit.

After a long time, Chen Changan finally felt the power of heaven and earth contained in the sword body of the Xuantie Sword.

He let go of all the distractions in his mind and tried to communicate with those forces.

Airplanes~

The Xuantie Sword suddenly trembled slightly, and it seemed to have some kind of resonance, and when it came into contact with Chen Changan's thoughts, it rushed towards him.

A quarter of an hour later, the power gradually disappeared, and the Xuantie Sword in his hand was finally overwhelmed and turned into a piece of scrap iron.

After a closer look, Chen Chang'an's cultivation has increased, but it is limited after all.

"It's very useless, it doesn't seem to work..."

A Xuantie sword was not enough for him to enter the next realm.

Since this method does not work, then the only way to climb Babel is to climb it again.

Outside the Tower of Babel.

Chen Chang stood quietly, looking up at the ninth-story Tower of Babel.

Last time, it took Chen Changan seven days to rise two levels in a row on the fifth floor.

However, after all, it was Chen Changan's first contact, and most of his time and energy were spent resisting the pressure brought by the Tower of Babel.

Stepping into the first floor, it was just that the strength was a little stronger, Chen Changan did not stop, and went straight to the next floor.

The second layer...

The third floor...

The fourth floor...

At the entrance of the fourth and fifth floors, Chen Changan slowed down for the first time.

"This time, I hope it won't disappoint!"

Chen Changan muttered to himself, calmed down a bit, and then raised his feet and stepped into the fifth layer.

Airplanes~

The strong oppressive force hit in an instant, and Chen Changan was prepared for a long time and quickly adapted to the pressure inside.

.........................

The day passed quickly.

When it was time to challenge the alternate inner courtyard students, there were already a lot of people around the challenge platform.

When the challenge was approaching, the challenged Fu Jie had already come to the scene.

"What's going on? The challenged have already come, why hasn't the challenger shown up yet?"

"Who knows, maybe I think I can't do it and hide, right?"

"You fart, how could Senior Brother Chen be afraid of that Fu Jie?"

Qianyuan couldn't help but explain to Chen Changan on the side.

"If it's not scared, then why don't you say he's here yet?"

The other continued to sarcastically mock Chen Changan.

"You don't have to guess, I saw Chen Changan enter the Tower of Babel yesterday, and now he should be on his way here. ”

At this time, a crisp and pleasant female voice came, and everyone looked back to see that it was the princess of Jinyang Kingdom-Jin Yuer.

"Babel, what is he doing there at this juncture?" someone wondered.

"What else can I do, of course, it's to go to the battlefield to sharpen the gun, it's the so-called temporary cramming, hahaha..."

...........................

"Challenge the alternate Inner Courtyard Academy?" Tutor Jin Feng was surprised, and cast an inquiring glance at Jin Yu'er.

Jin Yu'er nodded slightly, she knew about it.

"It's just nonsense! This stinky boy has average qualifications in cultivation, so it is far better to put his mind on the path of refining medicine. "Old man Zhang has a little hatred for the appearance that iron is not made of steel.

Chen Changan, a newly admitted student with ordinary qualifications, went to challenge the alternate inner courtyard student, and no one was optimistic about him.

In Zhang Lao's mind, Chen Changan will become his most proud disciple in the future, and he doesn't want to let him go out and embarrass him.

"What are you supposed to do, old man go out. ”

After Zhang Lao dropped a word, he turned around and left the Elixir Pavilion.

"Elder Zhang, I'll go with you. ”

Outside the Tower of Babel.

Chen Chang'an was in a very good mood, this time it only took one day, and his cultivation was promoted from the peak of the sixth layer of the transformation to the eighth layer of the transformation fan, which was much faster than he imagined.

"You've learned to make a date with others!"

Chen Changan had just walked out of the Tower of Babel, and was suddenly startled by a voice full of anger.

Looking up, Zhang Laozheng was glaring at him angrily.

"Elder Zhang, why are you here?" Chen Changan was a little confused.

"Are you embarrassed to say, why didn't you tell me about your challenge to the alternate Inner Courtyard student? Are you still sure to take it seriously?"

"Elder Zhang, I haven't had time to tell you yet, I'm thinking about going to you after I come out. ”

Chen Changan was helpless, so he had to laugh with him.

"Is the task I gave you completed? If it is not completed, you are not allowed to go anywhere today!" Zhang Lao did not intend to let Chen Changan go like this.

"First, this challenge, the younger generation has confidence. Second, in the past few days, I have basically learned what my predecessors explained. Chen Changan did not back down.

Have you had the confidence to learn?

Old man Zhang almost blew his beard in anger, his eyes flashed, and he said with a smile: "You just said that you basically learned what I explained in the past few days?"

"That's right. Chen Changan is full of confidence.

"Don't be ashamed!"

Zhang Lao snorted coldly, obviously not believing: "I'll ask a few questions, if you can answer them, no one will stop you from this challenge." ”

"Okay, that's a deal. ”

Chen Changan and Old Man Zhang, after a short-for-tat confrontation, reached an agreement again.

"The old man naturally won't break his promise, and Mentor Jin Feng can testify. Old man Zhang smiled, and then spoke pleasantly.

In his opinion, Chen Changan is a little too arrogant, and taking this opportunity to knock one or two can prevent this son from challenge, which can be described as killing two birds with one stone.

Next, Zhang Lao began to ask Chen Changan questions about "Basic Knowledge of Alchemy Medicine" and "Fire Control Heart Formula".

The focus is mainly on "Basic Common Sense of Alchemy", because "Fire Control Heart Technique" is too obscure and esoteric compared to novices, and Zhang Lao does not want to deliberately make things difficult for Chen Changan.

In fact, when Zhang Lao explained these two books, he didn't plan to let him learn them at all, the purpose was to let him get familiar with and understand them first.

It's only been two or three days, and Chen Changan actually boasts that he has basically learned it, of course he doesn't believe it.

The geniuses he has seen are like carps crossing the river, and those who are pretentious are mostly the superficial ones who comprehend things.

"The first question, what is alchemy?"

For the first question, Mr. Zhang started with the easiest.

"The so-called alchemy is to extract the essence of all things in heaven and earth and condense it into a common form of elixir, or other forms. Its characteristic is that it is a "refining", the art of alchemy in the world, which is almost indispensable to the auxiliary ...... of flames."

Chen Changan talked eloquently, not only answering the old man's question, but also drawing inferences.

The first question is very simple, Chen Changan can answer it, and several people are not surprised.

Immediately after the second question, Zhang Lao began to increase the difficulty.

"Let's talk about the selection and matching of alchemy materials. Zhang Lao looked at him quietly.

"Between heaven and earth, everything has its own attributes, and materials with different attributes contain different essences of heaven and earth. Some spiritual objects in the world contain different attributes and some unique characteristics, which are extremely complex, but there are certain rules to follow......"

Chen Changan replied fluently, and a huge amount of information came to his mind.

"In the process of refining medicine, how to use Danhuo, how to control Danhuo, and what ...... need to be paid attention to in the process of fire control" The difficulty of Zhang Lao's question was further increased.

For a novice, it is almost a bit harsh to ask him questions about "Danhuo", "fire control".

"Hehe, before the Xuan Realm, the alchemist was not able to cultivate his own Danhuo, so he needed to quote the Danhuo from the outside world, these Danhuo can be obtained from various sources, such as high-grade black cloud carbon, burning can form alchemy flames, but the quality is not high. There are also some fire-attribute crystals that can produce high-quality Danhuo ......"

Chen Changan still answered very easily, and said thousands of words in one breath.

This time, Zhang Lao was slightly surprised and hid the joy in his eyes.

Mentor Jin Feng was also surprised, she knew very well that Chen Changan was just a novice who had just entered the way of refining medicine.
