In four months, Chu Du has figured out a lot of things, it turns out that the world he is in now is called Xuanhuang World, this is completely a world composed of cultivators, the human race in this world is composed of native human races and countless people from small worlds entering here, the tendons and veins in the body are connected when people are born here, as long as the body can withstand the pressure brought by the first spiritual energy entering the body, you can enter the cultivation family or sect to test whether you can feel the spiritual energy between heaven and earth, and after passing, you can continue to cultivate, and if you don't pass, go back and be a mortal。

The mortals of the Xuanhuang Great World have a very high chance of passing the aura test, unlike those mortals in the small world without aura, who have such strict requirements to pass the test.

Some people once speculated that maybe the bodies of all the people in the Xuanhuang Great World were nourished by the rich aura, so their bodies were very little polluted by impurities between heaven and earth, so they could achieve the point where almost everyone cultivated immortals.

Someone has done an experiment to bring some mortals from the small world without aura to live in the Xuanhuang world, and after generations of reproduction, the probability of descendants passing the test has indeed increased, which also proves the previous guess, but there is no shortage of people in the Xuanhuang world, and no one has done this waste of time.

No one knows how big the Xuanhuang Great World is, at least Chu Du has not seen any record of this from the Giant Yang Sect's book called "Detailed Explanation of the Xuanhuang Great World", this book says that it is a detailed explanation, but in fact, the information of the continent where the Giant Yang Sect is located is recorded in detail, and the rest of the continents are only a passing mention.

The continent where the Juyang Sect is located is called the Tianyu Continent, and there are countless immortal cultivation sects on the continent, and these immortal cultivation sects are not in harmony with each other, but they are often fighting each other in order to compete for cultivation resources, and every day there are I don't know how many sects are destroyed, and those sects that win in the end are naturally stronger to a higher level.

The Giant Sun Sect is located in the relatively remote southwest corner of the Tianyu Continent, and was founded by the Venerable Venerable Furen, a monk at the peak of the Yuan Infant 2,500 years ago, and the name of the sect is taken from the fire system exercise "Juyang Decision" practiced by the Venerable Master of Fury , This exercise can greatly enhance the power of the fire spell, and the strength of the Venerable Venerable Venerable is naturally stronger than that of the ordinary Yuan Infant Monk, of course, the Giant Sun Sect at that time was unrivaled in power, but the Venerable Venerable Flame also failed to enter the realm of transforming the gods, and when the limit arrived, it naturally became a pile of loess, and the strength of his dead Juyang Sect was naturally greatly reduced, and what was more serious was that the Juyang Sect had never produced a Yuan Infant monk so far, and the resources that had been robbed before were naturally unable to hold, and now the disciples could not rob other sects, and they had to rely on picking up people from poor places such as the Nether Realm to become disciples！

"Damn, the principal has stayed here for too short a time, and he doesn't know the current situation of the Giant Sun Sect at all, and he still opens his mouth and closes his mouth Immortal Dao Sect Giant Yang Sect. Chu Du complained after knowing all this.

No wonder Chu Du saw that the head was busy every day, either farming or refining medicine, and he didn't even have time to teach Chu Du to cultivate, at first Chu Du thought it was the head of the family's hobby, but it turned out that he was forced to have no choice!

However, now that they have joined the Giant Sun Sect, they can only take one step at a time, fortunately, the aura in their body has been able to fight with the true qi in their body after such a long period of cultivation, Chu Du is ready to try to refine the true qi in his body in one fell swoop in a few days, but whether this vein can withstand this aura is a problem.

Because the people who entered the Giant Sun Sect with him had been cultivating for so long, Chu Du was a little anxious, he was eager to improve his strength as soon as possible, so that he could go out and hunt demon beasts in exchange for spirit stones, without spirit stones, his system was just an ornament.

On this day, when Chu Du loosened the spiritual fields in the courtyard and was about to take a rest, the head also came to the courtyard, and in the past few months, because Chu Du has become more and more proficient in farming, the head of the house has rarely come here except to come over to take care of his medicinal materials.

The head of the house looked at the soft spiritual field that had been planed by Chu Du, nodded with satisfaction, and then asked a question that Chu Du didn't expect: "How is the spiritual energy in the body, can you drive away the true qi?"

This made Chu Du a little stunned and very happy at the same time, it was not easy, he finally began to care about his cultivation!

Chu Du hurriedly replied: "It should be in the next few days, Master Xie cares." ”

"If it weren't for the fact that all the disciples they accepted were Qi Refiners, you would be a mortal and make me embarrassed, I care about your fart!" The words of the head made Chu Du feel that his hot face was attached to his cold ass.

"Take this strong tendon pill and take it, you will be strangled to death by your own aura. The words of the head of the house made Chu Du eager to hug the head of the house and kiss him a few times, and kept patting the master's ass.

The head of the sect listened to Chu Du's sycophants for a while before continuing: "This pill is worth 50 spirit stones, and 5 spirit stones will be deducted from your salary every month. After saying this, the head of the house left directly, leaving Chu Du with a confused face to stay in place.

"Feelings, I have been a sycophant for nothing, you want to accept my spirit stone, you are still standing here and listening to me for so long?" Chu Du looked at his master's back and complained, originally he wanted to give him a middle finger, but if he thought about it, it would be miserable to be discovered, and besides, he had only saved 25 spirit stones after deducting food and accommodation expenses from his salary in the past few months, and he had to save a few months if he wanted to buy a strong tendon pill at the price that the master said, and now the master was willing to give him credit It was also a great help to him.

He returned to his room with the strong tendon Dan Chudu given by the master and prepared to refine it, the pill in his hand was the size of a dragon's eye, dark red in color, and exuded a strong pungent smell.

"This also smells too bad!" Chu Du pinched his nose and muttered to himself, but no matter how bad it smelled, he had to eat it, Chu Du raised his head and swallowed the pill directly.

Immediately, Chu Du hurriedly sat cross-legged on the bed and entered the state of inner vision, only to see that as soon as the pill entered the body, the layer on the surface immediately turned into a pure medicinal power and poured into his tendons, Chu Du immediately felt that the tendons and veins where this medicinal power entered were like being roasted by fire, and he wanted to jump up directly in pain, but the remaining inner layer of the elixir also dissolved and followed by the previous medicinal power into the tendons, Chu Du immediately felt that the pain of being roasted by the fire disappeared a lot, and the severe pain became bearable.

After half an hour, these two medicinal forces swam through all the tendons and veins in Chu Du's body before disappearing completely, and Chu Du, who had watched the whole process, also exhaled a breath of turbidity, with a satisfied expression on his face.

"Although 50 spirit stones are quite expensive for me now, the value of this pill is definitely worth this price, my muscles and veins have been strengthened by the medicinal power of this pill, and I believe that there must be no problem after receiving that aura that has devoured true qi!" Chu Du said happily as he looked at the tendons in his body.

The next few days will continue to grow this aura with all his might, Chu Du doesn't think that he will lag behind those people, because he has the absolute advantage of the system, as long as there are spirit stones entering the space to cultivate, who can compare to his cultivation speed?

As long as Chu Du enters the Qi training period, his physical fitness will be further improved, although he can't use spells at this stage, but with the good foundation that the system has laid for himself in the Nether, Chu Du feels that he and those first-level demon beasts who were killed by Senior Brother Hu are not without the power to fight, and his income will also increase greatly at that time, with the first starting capital, the system will come in handy, and his strength will become stronger and stronger!

Seven days later, Chu Du looked at the aura in his dantian, his face was full of joy and at the same time, he was extremely surprised, because the true qi in his body was not refined at all, but the aura and the true qi were fused together after a fight in his dantian, becoming you have me and I have you, Chu Du now doesn't know whether the qi in his body is called true qi or aura, but after Chu Du studied for a long time and didn't find any abnormalities, he didn't bother to care about it anymore.

On the one hand, the role of running the Great Zhou Tian is to continue to strengthen and expand his own muscles and veins, so that the muscles and veins can withstand more spiritual energy operation, and at the same time, it is also to nourish the flesh and make his physical fitness stronger, on the other hand, it is also to refine the impurities in these aura, so that the aura in the body is more pure, and the operation is more handy.

The true qi in Chu Du's body is actually essentially formed by the transformation of his qi and blood power, Chu Du feels that it is necessary to continue to cultivate his body, so that he can greatly strengthen the aura in his body, but "Health Song" has been removed from the system, which makes him feel extremely heartache.

Moreover, the Juyang Sect is not a body refining sect, Chu Du has no exercises if he wants to cultivate the physical body, and there seem to be very few cultivators and immortal cultivators in this world, because there are so many longevity yuan in each realm of monks, and each realm is very difficult to break through, and most of the longevity yuan of monks is often used to break through the realm, even so, many monks do not enter the next realm until they die, and the gains and losses of both cultivation often outweigh the losses.
