Hearing this, Chen Ziyu was stunned for a moment, and only found that his strength was a little insufficient when he encountered danger today, so he immediately entered and exchanged for a lottery.

Without hesitation, he opened the lottery, and this time, he was lucky and drew something good, a spirit pill.

When he took the Gathering Spirit Pill in his hand, Chen Ziyu realized that this Gathering Spirit Pill was not the kind of Gathering Spirit Pill taken by low-level cultivators in the cultivation world, it contained a strong spiritual power that made him excited, and this Gathering Spirit Pill was completely able to allow him to break through the fourth layer of Qi refining in a short time.

Although he had just broken through the third layer of Qi refining, being able to advance so quickly would make the foundation a little unstable, but Chen Ziyu didn't care, because of his Heaven Devouring Technique, he was not afraid of making too fast progress and causing the foundation to be unstable, if the resources were rich enough, his progress at this time would be even more terrifying.

As mentioned above, it took Chen Ziyu nearly half a year to cultivate to the second level of qi refining back then, which shows how poor his qualifications are, but he was able to strike later and reach a realm that thousands of low-level cultivators could not even imagine, all thanks to his contribution to this Heaven Swallowing Technique.

Just as he was about to leave, the voice of the lottery system sounded again, "Additional designated tasks, the host needs to kill a hundred vicious people within two months, reward three lottery chances, punishment: deduct three lottery chances, and double the energy exchange value." ”

Hearing this rich reward, Chen Ziyu's eyes lit up, but after hearing this punishment, it was like a basin of cold water poured down.

However, with the experience of the last time, he also has some confidence in his heart and returns to the real world.

Because there was nothing else to do, Chen Ziyu decided to retreat and cultivate, and asked Xu Wanyun to deliver the food on time, because the fourth layer of Qi cultivation could destroy the female ghost, Xu Wanyun was naturally happy, and the dishes were sent differently every day.

Wang Chuyao was very dissatisfied with Chen Ziyu's skipping class, but although she was his teacher, she was embarrassed to interrupt him, and she now roughly understood that Chen Ziyu did not seem to be a simple character.

Time is in a blink of an eye, a week has passed, logically speaking, Dashan is dead, then Li Fengyun will definitely not let Chen Ziyu go, but after such a long time, he didn't move at all.

In fact, it's not that Li Fengyun doesn't want to make a move, he has to rush back to the headquarters because something has delayed, Chen Ziyu is an ancient martial artist who can kill the mountain, so now he can only deal with Uncle Fu in his hands, but this is a personal bodyguard, so naturally he can't be sent out.

Finally the matter was over, Li Fengyun answered a phone call, and suddenly became angry, with a thick anger rising in his eyes.

It turned out that since Li Yu was abolished, his whole personality has changed greatly, and sometimes even his father dares to scold, this call means that Li Yu has tortured three girls to death this week, and he is extremely perverted.

Li Fengyun secretly scolded this Li Yu for not being angry, but said to the person on the other end of the phone: "You can handle this matter well, don't disturb the police." ”

Li Fengyun turned to look at Uncle Fu and said, "That black tiger can't be found for the time being, this time you personally take action and arrest that kid for me." ”

Uncle Fu nodded.

It's been a week, and after forgetting to sleep and eat, the true qi in Chen Ziyu's body has been full, and he has begun to sprint to the fourth layer of qi training.

These four layers are a big leap forward, so it is relatively difficult to break through, Chen Ziyu held the spirit stone that had been consumed half in his hand and began to sprint.

When night fell, a faint fluorescence appeared on Chen Ziyu's body, looking extremely sacred.

Finally, as the body lightened, the whole person was like a rain, and the pores of the whole body were constantly dilating and swallowing the aura of heaven and earth.

The coveted fourth layer of qi refining has finally been reached.

The Qi refining period is also divided into middle and late stages, the initial stage is one to three layers, the middle stage is four to six, and the later stage is seven to nine, so at this time, he has already entered the middle stage, and many means can be used.

Chen Ziyu stretched out his palm, and out of thin air, there was an extra flame burning in his palm.

The biggest change in the fourth layer of Qi refining is that the True Qi is released, and the True Qi can be used to cast spells.

Because Chen Ziyu had already practiced in his previous life and had sufficient experience, some small spells could be used directly, of course, more powerful spells, some needed to open up the meridians or need to be re-cultivated for special cultivation.

Standing up to soothe his body, refreshed, and full of energy, Chen Ziyu's whole body suddenly changed, because he felt that a strong aura was rushing over, and the target was his house.

"Is it finally here?" Chen Ziyu smiled slightly, although this aura was strong, if he didn't break through the fourth layer of qi refining, it might be difficult for him to win, but now, his strength has simply undergone earth-shaking changes.

This time, he directly took the initiative to greet him, this university town is built in a hilly area, so some small mountains are still preserved, Chen Ziyu looked at an old man with strong spirits, and secretly said in his heart, the martial artists of this world also have a way to practice.

He can now see at a glance that this Uncle Fu has a force in his body, this is the internal force of a martial artist, although it is not as good as the true qi cultivated in his body, but it is somewhat similar, if what is said in the book is true, maybe there are really people in this world who can achieve the Jindan Dao.

This is the book that Chen Ziyu has read beforehand, so he learned some myths and legends.

Seeing this internal force, Chen Ziyu began to believe that there were people in this world who could enter the Dao with martial arts and cultivate the Jindan Dao.

"A hero is a young man! Compared to my uncompetitive apprentice, I have already been poisoned by you, I don't know what kind of school the little brother inherits?" Uncle Fu looked at Chen Ziyu, who took the initiative to greet him, smiled slightly, and did not make a direct move.

Chen Ziyu could also see that this Uncle Fu did not have much hostility towards him.

"Old man, it must be Li Fengyun who asked you to kill me! Don't worry, I'm a wild man, I don't have a teacher, it's just that the old man is so old and can't enjoy Qingfu well, why do you have to interfere in the affairs of Hongchen?"

"Alas, the old man has a hard time, little brother, come with me!" Uncle Fu did not continue to talk, revealing his intentions.

Chen Ziyu shook his head slightly, the martial arts master is a superman in the eyes of ordinary people, and he can be regarded as the number one person in the ancient martial arts world, but in his eyes, there is still a gap.

Seeing that Chen Ziyu didn't speak, Uncle Fu could only make a move, only to see him take a step across, his figure began to become ethereal, stretched out a hand and grabbed him, and locked him with a momentum.

Chen Ziyu's face was expressionless, and a flame suddenly shot out from his hand and collided directly with it.

Uncle Fu felt a terrifying danger, and suddenly the internal force in his body gushed out, and boom, a ball of fire flashed.

Uncle Fu stepped back with a shocked face, only to see that the palm he had just stretched out had turned pitch black, as if it had been roasted by charcoal fire.

Feeling the stinging pain coming from his palm, Uncle Fu's whole person was shocked, what kind of means is this? If he hadn't used internal force to wrap his palm in time, I'm afraid that his whole hand would have been gone by now.
