Seeing that sun Shangxiang was very satisfied with his place of cultivation, Ge Chen walked over with satisfaction.

Sun Shangxiang saw that GE Chen was also coming, and his pretty face was flushed, mostly because he was embarrassed by his behavior. Later, she took out some spells from her storage bag and gave them to ge Chen.

Among them, there is a magic skill that he practiced when he was wandering in the period of practicing Qi: derivative formula.

Ge Chen took the derived formula in his hand and opened it anxiously.

On the other hand, sun Shangxiang found a big smooth stone and sat down cross legged to concentrate on his cultivation.

Ge Chen took the magic book, but also calm down to watch, began to put into practice.

According to the way of cultivating immortals mentioned in the derived formula, he started to run the spiritual power on his body, constantly gathered it together, and then slowly injected it into various meridians in his body, and then began to wash all parts of his body with the spiritual power.

The two people who devoted themselves to the cultivation were all absorbed, without any distraction.

About a quarter of an hour later, Ge Chen had already made a small profit. He sat up straight with a happy face, stretched his waist with some pain, and continued to put his whole body into the derived formula.

This derived formula was developed by people who were very early in the cultivation of immortals. The method of moistening meridians introduced in that book is the most exquisite secret that GE Chen has learned since he cultivated immortals. The magic and skills introduced by GE Chen benefited him a lot, and also enabled him to gather more aura during the Qi training period.

After a long time, Ge Chen stood up excitedly from the big stone. He felt very satisfied and was ready to settle down and make an impact on the fourth level of Qi training period.

Moreover, when GE Chen was preparing for the impact, he suddenly felt that the spiritual power in his body had increased dramatically. How could this not surprise gerchen.

Ge Chen was overjoyed and naturally thought of a way to impact the next layer.

The spirit power in the body slowly gathered, and then became more and more full. Seeing that the time seemed to come, Ge Chen was lucky and ready to attack the fourth level.

"Hoo Spit out a mouthful of turbid gas, Ge Chen starts to transport the whole body's spiritual power all over his body.

At the critical moment of the impact, Ge Chen only felt a burst of pain in his body, and the meridians of his whole body seemed to be distorted for a while, and then there was no feeling at all, and the previously condensed spiritual power disappeared out of thin air.

Ge Chen was so stupid that he stood in the woods, his eyes empty and confused.

After a while, he sighed helplessly. It seems that the impact on the fourth level is a failure.

Ge Chen seems very depressed. He is supposed to have a very good chance to attack the fourth level of Qi training. How could he fail without any reason? Moreover, the aura in his body seemed to disappear all at once, without any perceptible sign, which surprised Ge Chen.

Although he failed for the first time, Ge Chen didn't give up, but he still picked up his spirit and continued to practice.

Ge Chen wrote down all the methods he had learned before. Although he didn't fully understand them, it's not impossible for him to memorize them and digest them in the future.

This morning, Ge Chen didn't know how many times he had failed. The aura that he finally gathered disappeared when he rushed through the pass.

Sun Shangxiang, who was sitting beside him, seemed to have no idea about it. He didn't say a word, and he was still cultivating himself.

When GE Chen failed to pass the pass again, he could not help but feel angry. He glanced at sun Shangxiang not far away from him and scolded in his heart: "yes, although this derived formula is magical, it makes Lao Tzu's aura disappear inexplicably. If it were not for the aura around the lake, I'm afraid he would have left here long ago, Find another place to practice. Is there something wrong with this girl's skill, but it's not like her

As soon as this idea came out, Ge Chen had some opinions about sun Shangxiang, who was still calm. He took a mouthful of his elder martial sister and cried out. The other side gave him a broken skill and put him aside.

The more you think about it, the more angry you are. Ge Chen even regretted that he had brought her here, but she spent a lot of money, and the girl was too bad.

Now Ge Chen's heart is not pure. He can't gather his mind and continue to practice.

Ge Chen, who couldn't figure out where the problem came from, set his eyes on sun Shangxiang, who was practicing hard. With a little dissatisfaction in his eyes, he stares at the girl who is still practicing. Ge Chen knew that if the elder martial sister gave the derivative formula to herself, she must know it very well. If she had been instructed by the other party, maybe she would have succeeded long ago.

After thinking about it, Ge Chen doesn't do the useless work. Instead, he hopes sun Shangxiang can help him.

As if sensing Ge Chen's eyes, sun Shangxiang took a breath and said, "younger martial brother, what's your problem?"

"Elder martial sister, you guessed very well. Younger martial brother, I seem to have reached a bottleneck in this derivative formula." Answered gerchen“ Younger martial brother, it's your first time to practice this derived formula, and you are too shallow to understand it. However, you are gifted and intelligent. The first level of the derived formula must be comprehension. "“ "The first level of understanding?" Ge Chen was speechless. He didn't get any benefit from the derived formula this morning. How could he understand it“ Younger martial brother, when you practice this derived formula, do you feel that you have lost your aura? " Sun Shangxiang asked. Ge Chen heard that he did experience this, but it didn't mean anything. He went back to "this is the case.". But I spent most of my time, and all the aura that I finally gathered fell short. " Ge Chen's chagrined words seemed to make sun Shangxiang smile. He covered his face with a smile and said, "that's right! The derived formula is about not breaking and not standing. When you first learn it, your mana will be consumed gradually, but it will be multiplied in the future. Younger martial brother, you should have a good understanding. When you learn the fourth level, you will naturally feel the mystery. "“ Oh, yes Although Ge Chen listened to the explanation, he was still unhappy. This derivative formula is so troublesome, so I have to wait until the age of monkey to reach a certain level“ Well, younger martial brother, I have some pills here. You can take them with your gas condensing pill. The effect will be better. " Sun Shangxiang took some pills from his storage bag, taught Ge Chen, and said: "this pill is called catalyzing pill. It has a very strong effect on catalyzing the gas condensing pill. Every time you take a gas condensing pill, and then take another one, the effect will be better." After taking the Dunning pill, Ge Chen thought of his own plan. In this way, Ge Chen practiced the derived formula more assiduously in his later cultivation. After all, this is his second skill besides the Qi training formula, and this skill is much better than the Qi training formula given by the old guy. As the months went by, Ge Chen finally reached the sixth level of Qi training, and he yearned for the cultivation of magic and the art of imperial weapons. However, five or six months later, sun Erzhu didn't show up, which made Ge Chen's heart suddenly sink. Did sun Erzhu encounter any trouble?
