After this power was extracted by him, it was injected into his Hell Sword Dao.
Immediately, Du Yutong's aging process slowed down.
Li Chengfeng took action again, but this time the power extracted exceeded two percent.
Although the "Drawing from the Source" technique cannot extract from the same point twice, Li Chengfeng had already anticipated these drawbacks, so his actions were precise, and each extraction was just right.
Through Li Chengfeng's efforts, Du Yutong's aging was finally temporarily contained.
She looked at Li Chengfeng gratefully, her heart filled with respect and gratitude.
She knew that without Li Chengfeng's help, she would probably...
Have already turned into an old woman, which was what she least wanted to see, as she valued her beauty very much.
Under Li Chengfeng's precise control, Drawing from the Source successfully extracted two-tenths of the backlash power within Du Yutong's body.
This action slowed down the momentum of aging, but the process was extremely dangerous.
Li Chengfeng then explained his plan to Du Yutong: "Senior, please listen to my explanation. I don't want you to transfer the aging to me, but I hope you will pass this power to me.
Because I have the ability to refine this power, but you cannot.
Although your strength is strong, in this aspect, I am indeed more advantageous than you."
Du Yutong was initially furious, but after hearing Li Chengfeng's explanation, her anger gradually dissipated.
She glared at Li Chengfeng, but the anger in her eyes had turned into jest: "You little rascal, you still call me Senior, you must call me Sister from now on, understand?
Well, considering that you helped me this time, I will temporarily acknowledge you as my younger brother."
Then, Du Yutong followed Li Chengfeng's guidance and condensed that strange backlash power into one point, and then slowly transmitted it into Li Chengfeng's body.
If this were in battle, she would never have done this, because the battle situation changes rapidly.
But now the two were facing each other alone, and Li Chengfeng had already taught her the magic, which she understood as soon as she heard it with her qualifications as a late-stage Nascent Soul cultivator.
As Du Yutong's power was continuously transmitted into Li Chengfeng's body, Li Chengfeng immediately guided it into his Sword Pool to nourish his sword energy.
This process not only solved Du Yutong's aging problem, but also improved Li Chengfeng's strength, which can be described as killing two birds with one stone.
However, this action also exposed Li Chengfeng's powerful strength.
He knew that doing so might attract some unnecessary trouble.
But he believed that Du Yutong was not the kind of person who would go back on her word, so he chose to trust her.
Of course, he was also fully prepared. If the other party had any malicious intentions, he could use the Substitute Technique to escape from here at any time.
Looking at Li Chengfeng's calm expression and confident eyes, Du Yutong couldn't help but feel a sense of admiration in her heart.
She knew that she had really met an extraordinary younger brother this time.
As Du Yutong's technique was performed, the negative energy in her body gradually passed to Li Chengfeng.
Li Chengfeng silently endured all of this, his expression remained unchanged, which made Du Yutong feel a little guilty.
She knew that Li Chengfeng was just a newly advanced cultivator, but he was enduring such a huge pressure for her.
However, Li Chengfeng did not show any discomfort. His face was calm, as if everything was under his control.
Du Yutong carefully examined this young cultivator and found that the power in his body was surging and turbulent, far exceeding that of ordinary cultivators.
Even compared to Foundation Establishment cultivators, Li Chengfeng's power was at least ten times theirs, and it was more precise and powerful.
This made Du Yutong exclaim in surprise, realizing that Li Chengfeng had surpassed the top-grade Foundation Establishment she had once reached and reached another level.
She understood the reason why Li Chengfeng insisted on following his own path. This fusion and enhancement of power was what he had been pursuing all along.
After five hours of cultivation, the negative energy in Du Yutong's body was finally completely cleared.
She felt an unprecedented power, as if she had already touched the threshold of the Half-Step God Transformation stage.
However, she also realized that now was not the best time to retreat and break through.
The Demon Clan's failure was likely to lead them to take more drastic actions, and she could not risk retreating at this time.
Du Yutong fell into deep thought, considering how to balance the current situation with her personal cultivation improvement.
Suddenly, she thought of her secret method of improvement, which could allow her to advance to the Half-Step God Transformation stage in a short time, but the price was also huge.
She hesitated for a moment, but ultimately decided to use this secret method.
Li Chengfeng saw Du Yutong fall into deep thought, he did not dare to disturb her, and just waited quietly.
Although he knew that Du Yutong's negative energy was getting weaker and weaker, he also understood that this was a critical moment for cultivation and could not be easily interrupted.
He believed that Du Yutong would make the right choice.
Du Yutong's heart was filled with mixed feelings.
As the owner of the Pure Marrow Body, she knew the rarity and power of this physique.
The Pure Marrow Body is incomparably pure, and no matter who you cultivate with, it can bring great benefits to the other party, and even help them break through their realm.
However, Du Yutong had always adhered to her principles. She looked down on those male cultivators, believing that they could not compare with her.
She firmly believed that she could reach the strongest realm through her own cultivation.
Over the years, she had always retained the opportunity to use the Pure Marrow Body for dual cultivation, hoping to find a suitable partner at the most critical moment and entrust her pure and flawless self to him.
However, as time passed, she had never met the person who moved her heart.
Now, facing the pressure of the upcoming Demon Clan invasion, Du Yutong could no longer hesitate. She had to improve her strength as soon as possible to cope with the upcoming crisis.
After careful consideration, she decided to take that step—to choose a suitable partner for dual cultivation.
Du Yutong was very cautious when choosing a partner.
She knew the importance of the Pure Marrow Body during dual cultivation. If the other party could not dominate the energy, she was likely to be absorbed by the other party and become their slave.
Therefore, she chose the person she thought was the most perfect—Li Chengfeng.
The power in Li Chengfeng's body was pure and powerful, he possessed the Pure Yang Body, and he maintained his virginity.
His mana was profound, surpassing the level of top-grade Foundation Establishment.
What moved Du Yutong even more was that she found that she was not repulsed by Li Chengfeng, but instead had a special affection for him.
After weighing the pros and cons, Du Yutong finally made up her mind.
She decided to cultivate with Li Chengfeng, using his power to help her break through to the Half-Step God Transformation realm.
She believed that only in this way could she be invincible in the upcoming Demon Clan invasion.
Thinking of this, she took a deep breath, the struggle in her heart finally subsided, and then she coughed lightly, withdrew the power she was running, and looked directly at Li Chengfeng.
In those beautiful eyes, like the lake in early spring, sparkling and full of spring.
Her skin, bathed in the sunlight, faintly revealed a light red color, like a shy peach blossom, blooming with a moving color.
This shyness was not deliberate, but a natural outpouring from the depths of her heart, as if a spring breeze was blowing across the lake, stirring up layers of ripples.
Li Chengfeng stared at the beauty in front of him, and was stunned for a moment. Since he began cultivating, he had come into contact with many female cultivators, and there were many who were known for their charm techniques,
But which one could compare with Du Yutong in front of him? That charm was not deliberate, but a natural outpouring from the inside out, as if she was born with a captivating magic.
And the tenderness and care in Du Yutong's eyes made his heart surge even more.
It was a feeling he had never had before, as if the whole world had become gentle because of it.
Although he was shocked in his heart, he was more grateful and fortunate. He could feel Du Yutong's sincerity and concern for him, which was a heartfelt expression of emotion.
"Sister, what's wrong? Are you feeling unwell somewhere?" Li Chengfeng asked with concern, his voice full of worry.
He looked at Du Yutong, his eyes full of concern and inquiry, "Does the magic you just used have any other drawbacks on you? Tell your brother, I'm thinking of a way to solve it."
