After thinking about it, Li Yifeng decided to practice this exercise, but the premise was that Princess Lan'er returned to her body, and the two of them needed to practice at the same time to completely separate the ghost body, and the exercise also needed to be improved.

After several months of improvement, this exercise has become suitable for the cultivation of the human race and the ghost race, although Princess Lan'er is reluctant, she has no choice but to return to the human body to cultivate the ghost qi diversion.

A few months later, after completing the first layer of cultivation without accident, Li Yifeng's body changed slightly, and the ghost qi spontaneously turned the entity into nothingness, and if he cultivated to the last layer, he would become a real member of the ghost clan.

"No matter how much it is, you can only know the results if you cultivate to the last level. Li Yifeng said decisively in his heart, and then continued to cultivate.

With the passage of time, it is not far from the completion of the exercises, which is also to wait for the progress of Princess Lan'er to delay so far, and at the same time, his real body has become a state of nothingness, as long as the foreign object touches it, it will penetrate through, and it cannot cause actual damage to the body.

Twenty years have passed in the blink of an eye, and the ghost qi diversion cultivated by the two has been perfectly achieved, and at this time, Li Yifeng's entire body has become nothing, looking no different from his soul, and everything in his body has also become a state of nothingness.

Li Yifeng didn't care about this, as long as he was willing, he could abolish the exercises at any time and restore himself to his original state, now it was just to verify the results, and once he succeeded, he would be able to separate from Princess Lan'er.

The two sat down without thinking, and at the same time used the ghost clan's secret technique to divert the ghost qi. At the same time as Li Yifeng's body was cast, his body gradually materialized, and all the ghost qi was condensed on his fingertips, and then it was pointed at Princess Lan'er's Heavenly Spirit Gai.

The whole process was not muddy, all the ghost qi was diverted away, and Princess Lan'er used it at the same time to divert the ghost qi to Li Yifeng, who was originally the daughter of a human ghost and instantly lost all her ghost qi and became a human race.

When the two were about to be happy, the ghost qi diversion was actually offset when the two of them were cast at the same time, that is to say, the two of them were relieved of their weak state under the effect of the ghost qi diversion, but the root cause had not yet been solved, causing Li Yifeng of the main body to be miserable.

The powerful ghost qi was scurrying in Li Yifeng's body, although he used the power of chaos in time to resist, the strength of the ghost qi was unpredictable, and his body swelled up under the surging of the ghost qi, and it rose to the size of one zhang in just a moment.

Princess Lan'er looked at the swelling Li Yifeng at a loss, and actually reversed the exercises to divert the popularity, and the two qi of people and ghosts devoured each other and complemented each other, and the expansion gradually stopped. The forces of chaos seized the opportunity to suppress the rampaging ghost qi, and in a matter of moments, they returned to their original state.

Li Yifeng, who was in pain, had an extremely ugly face, half of his face showed a hideous demonic color, and the other half of his face was forced to endure the pain and become distorted. Under the action of the two forces of humans and ghosts, only those who cultivate the holy recipe can survive.

The tug-of-war with the demon lasted all day, and with the help of the power of chaos, his life was saved, and there was indescribable pain all over his body, his limbs fell to the ground weakly, and his entire robe was soaked with sweat.

Princess Lan'er's popularity diversion had no countereffect, let alone entered a state of weakness, tears rolled down her eyes and dripped on Li Yifeng's distorted cheeks, slowly evaporating with time.

A few months later, Li Yifeng came to his senses. As soon as he woke up, he noticed that someone was "holding" him, and the entity's body turned into nothingness and penetrated Princess Lan'er's hands.

This scene woke up Li Yifeng, and when he saw the sleeping Princess Lan'er's body recover to his body, he stretched out his trembling hand and stroked Princess Lan'er's cheek, and found that his hand penetrated through the past, and when he looked into the dantian, he found that there was an invisible qi in the chaotic dantian.

Immediately after a while, the entity was restored, and an inexplicable sour smell surged up on the cheek of Princess Lan'er's entity, and after adjustment, the former beloved was buried in his heart forever.

"Originally, I thought that the diversion failed, but Princess Lan'er desperately diverted her popularity to create me now, and using this magic power properly will be a trump card. Li Yifeng said with a smile.

The two of them who were blessed by misfortune stayed in the ghost ruins for a while and then left this place, and before leaving, Princess Lan'er took all the treasures in the bamboo shoots with her, which was considered to be a preparation for her own foothold in the demon world.

After leaving the cave, the entire cave collapsed due to the mechanism inside the treasure, and the entire river disappeared in an instant, and the water was absorbed by the rock and became a part of the rock.

The two came out to the ground and saw Shan Lao meditating, and Li Yifeng was moved by the waiting day and night, but now that there is a thinly clothed woman for no reason, how to explain it has become a difficult problem now.

Yu Tianshan opened his eyes and saw Li Yifeng and a female cultivator who had never met, the expression on his face could be described as colorful, and doubts surged up on his forehead for a moment.

"This girl's appearance is overwhelming, good boy, where did you get it from? Shan Lao said with surprise and joy.

"This is not the place to talk, let's go back to the city first. Li Yifeng's keen senses found that something was wrong.

"Also, after you go back, you kid should tell me what you have discovered during this time? The old man has lived for so long and has never encountered such a good thing. Elder Shan teased meaningfully, and then the three of them left the place.

About a day after leaving the ghost ruins, a late merger monk was found in the distance, this high-ranking person followed the mark of the Holy Son, but unfortunately he was not able to hide his figure and was discovered.

"I can rest assured when I see you, don't stay outside for too long, the Demon Queen asked her subordinates to find the Holy Son back to the city, the cross-border passage has changed earlier, and the Demon Queen wants to send the Holy Sons to the Spirit Realm in the near future. The senior of the merger said urgently.

"It just so happens that the matter has been settled, and you can go there at any time when you return to the city. Li Yifeng said happily, taking Princess Lan'er's tender hand and following this high-ranking person back to the city.

After a long flight, he finally returned to the imperial capital, and after arranging Princess Lan'er in the inn, he went to Tianjian Peak to report, and the demon queen saw that all the holy sons were safe and sound, so she announced that she would go to the spirit world in a year, and explained that all the holy sons were not allowed to leave the imperial capital.

Li Yifeng, who returned to the inn, informed Princess Lan'er about going to the spirit world, and although the time between the two was short, the relationship was cultivated. Li Yifeng has always regarded Princess Lan'er as her sister and takes good care of her. Although Princess Lan'er talks about her brother, she regards her brother as a lifelong entrustment in her heart.

Li Yifeng spent the remaining year teaching his life's experience to Princess Lan'er, and it was too dangerous for Princess Lan'er to see the world for the first time in this dangerous demon world. In addition to the cultivation experience, he also taught the experience of being a person, and all the big and small things were recorded in the jade slip so that Princess Lan'er could read it at any time.

In addition to oral teaching, there is also a need to practice fighting experience, and Yu Tianshan also imparted his own experience in it, and also gave a lot of Demon Realm exercises, so that Princess Lan'er can have a foothold in the Demon Realm.

Just one year passed quickly, and during this time, Li Yifeng taught everything he had learned all his life to Princess Lan'er, and everything in life was accommodating, but he was extremely reluctant to part at the moment of separation.

No matter how long it is delayed from the inn to Tianjian Peak, there is a time when she reaches the end, Princess Lan'er is reluctant to let go of Li Yifeng's hand, and the tears in her eyes are low and her heart hurts.

"Silly girl, my brother is just temporarily separated from you, and he will naturally come back after the mission is completed, and there is the dream sister Fluttershy that I told you, she will be your second mentor in life, and the note she left behind will soon be out of the customs, and I will go to her when the time comes. Li Yifeng wiped away the warm tears and said gently.

"Brother will definitely come back, no matter what the world is, Lao Lan'er will wait for you to come back. Princess Lan'er cried and said, hugging Li Yifeng for a long time and couldn't calm down.

"Silly girl!"

No matter how ruthless he is, he can't say the word "parting", so he can only bear the pain of his heart silently. Nudge Princess Lan'er's shoulder, wipe away the ugly tears, and leave!

"Your real name must not be said, in the future, you will be called Li Qinglan, live well and wait for your brother to come back. When Li Yifeng left, his divine sense transmitted the sound, and the unique ghost qi transmission voice could not be detected by anyone.

"Silly girl, your brother will definitely come back, the old man has never looked at the wrong person. Yu Tianshan said comfortingly, and then followed the guards to ascend to Heavenly Sword Peak.

It just so happened that at this time, Dream Fluttershy came out of retreat, and saw Li Yifeng ascend to Heavenly Sword Peak, and the words that had accumulated in his heart for many years had no chance to be spoken, but he heard that Chuanyin wanted to take good care of his sister, so the two women who were tempted by him in the demon world shed ugly tears.

And at the peak of Heavenly Sword Peak, all the Holy Sons were ready, and Li Yifeng's arrival made them a little dissatisfied, but standing in the same boat, they could only swallow their dissatisfaction alive.

"Why is there a Merge Stage Monk?" said the Demon Queen with some surprise.

"After the Demon Enlightenment, the original selection of the Holy Son Demon Lord made a condition that a Holy Son could bring an elder to the Spirit Realm, and it was also this condition that many families participated, but the later Holy Son was arranged by Zhixiang and was not accompanied by a high-level person. A general said respectfully.

"It doesn't matter, as long as the number of Holy Sons is enough, go and ask Tianya Zuo Protector to come here and take them to the cross-border passage, and leave the rest to him. The demon queen said expressionlessly.

A moment later, Venerable Tianya came to the peak of Tianjian Peak, took out the manned flying boat from the storage ring, and all the holy sons were arranged in a separate room, Li Yifeng and Shan Lao were naturally in the same room.

The flying boat took off and headed for the cross-border passage, the speed of the high-level flying magic weapon was naturally fast, and it took a month to reach the cross-border passage, where it had already deployed heavy troops to welcome the arrival of the Holy Son, and at the same time prevent other families from taking the opportunity to blend in and disrupt the entire plan.
