"of course, there are fireball, ice shield, vine and so on. After learning the magic arts, you can take the inner door tasks. The contribution value you get from completing the tasks can be exchanged for pills to increase the cultivation speed, for magic weapons, for magic stones, and so on."

"You have to exchange all these?" Yi Heng asked in surprise.

"Of course, there are so many people in the sect. How can they have resources if they don\'t work for the sect?"

It has been an hour since Xiao Wuji came out. In addition to getting the skill and a bottle of Bigu pill, he also knew a lot of information.

For example, before the fourth level of Qi refining, the sect only provided the first four levels of skills and PI Gu Dan. After the fourth level of Qi refining, you can take the tasks issued by the sect, or you can go to the secular world to kill monsters or collect medicinal materials.

Yi Heng is very interested in learning fireball technique. After all, the appearance and power of fireball technique still make Yi Heng\'s heart palpitating.

When I went down the mountain, I also met several Taoist priests in Qingyi. However, Yi Heng was immersed in his own joy and did not pay attention to it.

Fortunately, I didn\'t meet the three of Zeng Yushu, and I didn\'t know what they were busy with.

Back in the courtyard, sitting on the bed, Yi hengcai had time to check the skills in his mind. The first to the fourth level of Qi refining was the initial skill. There was no magic at all, just accumulated aura.

The first layer of Qi refining is to open up the elixir field in the body. The ordinary people in Dantian also have some, but they can\'t store aura. Now Yi Heng needs to open up his own elixir field to store aura.

In addition to opening up the elixir field, the symbol of the first layer of Qi refining is to store the aura in the elixir field. Only one trace of the aura is stored in the elixir field. Use this aura to run along the corresponding meridians of the skill and return to the elixir field.

If there is no loss of Reiki, it means that the first layer of refining gas is complete, which can impact the second layer. If there is loss, it means that the aura is used to wash the impurities in the meridians during the operation, then it should be washed with Reiki until there is no consumption.

The second layer of Qi refining has several times more aura than the first layer, so the breakthrough is actually to expand the elixir field and expand the meridians.

The expansion of the elixir field can store more aura. The expansion of meridians can attract more Aura to enter. It can also increase the output of aura. The power of natural magic will be greater.

After knowing this, Yi Heng has a low heart. In the future, he only needs to practice hard. His only worry is that he has too poor qualification and when he can reach the fourth level.

Yi Heng finally realized that there were so many impurities in his body because of his five elements miscellaneous spirit root.

The next day Yi Heng opened up the elixir field the day after he got the skill. Then he had a trace of aura in the elixir field. When running with this aura, the aura was consumed before it reached 1% of the total. Yi Heng, who thought it was easy to practice, was greatly disappointed.

Five months later, the aura in the elixir field was able to run for a week, but there was no aura back to the elixir field.

Three months later, half of the aura can be returned to the elixir field after a week\'s operation.

Another two months later, the aura of returning to the elixir field was finally a little bit more, and so far, Yi Heng finally achieved a level of gas refining.

Yi Heng looks at his shoulder length hair, and finally knows why other people\'s hair is combed into Taoist hair. In fact, he is not a Taoist. Is he afraid that his hair will grow too long for too long?

In the past ten months, Yi Heng hardly ever went out of the courtyard except to get the Bigu pill every month.

It seems that there are more disciples from other schools. Occasionally, some people play in the river.

Zeng Yushu also met twice, but every time he was tired and in a hurry. He did not have time to say hello. But Yi Heng could see that Zeng Yushu had already known his true identity.

In fact, he was not afraid. After all, he did not say any lies. They guessed everything by themselves. He just said some ambiguous words according to their guess.

It is strange that Zeng Yushu did not come to find trouble for himself, and the other two did not come to him.

He didn\'t know that Zeng Yushu broke through to the fourth floor six months later. After practicing magic arts, he had been taking on the task of the sect. The other two people were inspired by him and tried to practice hard. How could he find him.

It is said that Zeng Yushu worked so hard to practice and do the task. In fact, it was his encouragement. If Yi Heng knew it, he would regret to beat himself twice.

In fact, he wished that Zeng Yushu had stayed on the third floor, so that he would not be afraid to meet him when he reached the third floor.

But where did he know that his practice was so slow? Others had reached the third floor in a year, and he thought that he would have had more time if he was worse. Who knows that it is only ten months before he is fully developed.

There is no time for practice. Spring and autumn come. Although the four seasons in the gate are not obvious, Yi Heng knows it after four years.

After breaking through one level, Yi Heng finally felt the joy of breaking through his cultivation. He not only felt comfortable and energetic, but also felt that he had a lot of quick thinking. Now he can analyze things that he could not think through before.I knew that when I met Xu Feng, I threatened him more than helped him. I would have been killed by him, but I didn\'t have more Aura, so I left my life.

Yi Heng\'s heart was full of fear. No matter how kind the immortal cultivator was, he would not regard the mortal as a human being. When he was threatened, he first considered not the size of the threat, but the elimination of all threats.

This is the world of the immortals.

But Yi Heng didn\'t flinch. In fact, his childhood experience has made him know the law of survival, but his fierce and aggressive courage has not disappeared. What\'s more, he has tasted the joy of breakthrough in cultivation?

After four years, it has finally broken through to the fourth layer of gas refining. The aura in the Dantian is much more than that in the first layer.

The meridians have been expanded four times, and the impurities in the whole body are almost washed away. Of course, for the five elements miscellaneous spirit root, some impurities will be produced every day, which makes the cultivation extremely slow.

Finally, he can learn magic. Yi Heng is excited when he thinks that he can make fireball.

Four years is enough time for a lot of things to happen. Zeng Yushu entered the inner gate the year before last, while Wei Guyun and Chen Beichen entered the inner gate last year.

No one has been to the courtyard where Yi Heng is. All the new disciples choose the spacious and bright courtyard.

In the past four years, Yi Heng and Xiao Wuji became more familiar, and each time he received Bigu Dan, he would chat with him.

It seems that Xiao Wuji doesn\'t need to practice. He is there all the year round, but with the growth of his cultivation, he feels more and more powerful in front of him.

Xu Feng has never appeared, seems to have been recuperating and healing, and seems to have forgotten Yi Heng.

After chatting with Xiao Wuji, he returned to the courtyard with his magic. Over the past four years, Yi Heng has regarded this place as his home, even if it is remote and dark.

Holding the jade slips, Yi Heng grinned bitterly. He thought he could get a lot of magic, but he could only get three of them. He had to choose from the Limited five.

Fireball, vine, ice shield, wind escape, yellow sand.

Yi Heng first chose fireball, after all, he knew its power.

The other two chose ice shield and flying escape at Xiao Wuji\'s suggestion.

These three magic arts are the most applicable among the four levels of disciples. They can attack, defend and escape.

Other spells must be exchanged for contribution points, which can only be obtained after completing the sect task. Therefore, he must learn the magic and start to do the task.
