Ye Xingchen was very happy when he heard the system's voice. Not only did he get 1000 points this time, he also got the Large Disk's reward.

Furthermore, Ye Xingchen had also obtained ten Demonic Beast s, and most importantly, during these seven days of time, Ye Xingchen crazily hunted Demonic Beast, and unexpectedly levelled up from the early stage of Postnatal Stage to the middle stage of the Postnatal Stage.

I finally have 1,000 points. Haha, I can finally exchange for a spirit technique. I'm one step closer to saving my little sister.

That day, Ye Xingchen returned to the Ye Family, and came to Ye Yu's room. At this moment, his mother, Liu Yun Lan, was still guarding Ye Yu.

Ye Xingchen asked about Ye Yu's situation. Knowing that it was temporarily stabilized with the help of the Spring of Life, Ye Xingchen was relieved and immediately went into closed door cultivation.

Returning to his own room, Ye Xingchen entered the War God's Space and pulled out the Marital God System.

"Wu, I want to exchange for a spirit technique." Ye Xingchen communicated with Wu Dai through his thoughts.

"Ding..." Does the system owner want to spend one thousand copies to exchange for the [Soul Refinement] technique? "

Ye Xingchen unhesitatingly chose "Yes", and his points were instantly deducted by a thousand. The contents of the [Soul Refinement] technique also entered Ye Xingchen's mind.

The secret technique, Soul Refinement, could cultivate Small Success and refine a few incomplete souls. After mastering it, it could refine any souls of a lower level than itself.

This magic technique was rather evil, and he hoped that whoever got it would try their best not to cultivate it.

After Ye Xingchen finished reading the introduction, he realized that this secret technique was an evil technique, but in order to save his sister, he still resolutely chose to train.

Ye Xingchen sat crossed legged inside the War God's Space, while the others looked at him from within the Swordheart Hall.

Ye Xingchen controlled the Spiritual Strength, and according to the guidance of the secret Soul Refinement, continued to temper it.

Only by tempering the Spiritual Strength to its peak would one be able to start training in the secret arts of the Soul Refinement.

Just like this, Ye Xingchen entered a long period of cultivation while Xiao Shi played happily in the Spring of Life.

"Big brother, do you think master can learn this technique?" Jian Er suddenly asked.

"It should be possible. Master must have had some other fortuitous encounters, take a look at the space we're in right now, even if the old master was in his prime he wouldn't be able to open it up. Also, look, there's a pool of Spring of Life there." Jian Yi said in a low voice.

The others also agreed, they had nothing to do now, so they stayed in the Swordheart Hall.

Time slowly passed, and Ye Xingchen was still cultivating.

Regarding the Secret Art of Soul Refinement, Ye Xingchen had to succeed in cultivating it, or at least have to cultivate the Small Success, this was the goal Ye Xingchen set for himself.

The so-called Soul Refinement, was to use the Spiritual Strength to suppress the soul, and finally finish refining. But after refining, there would be a qualitative change in his own Spiritual Strength.

In ancient times, there were some disciples of evil sects that would refine other souls to strengthen themselves. In the end, these evil sects would be destroyed because this cultivation method was too wicked.

But if the Soul Refinement did not succeed, it would suffer from backlash, and if it was light, it would be heavily injured, and if it was heavy, it would die.

The Spiritual Strength circled around Ye Xingchen's mind, and traces of red energy appeared. When this red energy entered Ye Xingchen's mind, it continuously fought against Ye Xingchen's Spiritual Strength, and was ultimately swallowed by Ye Xingchen's Spiritual Strength.

It had already been seven days. With half a month of time, Ye Yu's life could be considered to have reached its end and even deities would find it difficult to save him.

Although Ye Xingchen was cultivating with his eyes closed, he was crying out in his heart that he had to succeed.

"Refine …" Ye Xingchen muttered to himself as the Spiritual Strength in his mind continued to refine the wisps of red energy that appeared.

Ye Xingchen also understood that this red energy was produced by cultivating the Soul Refinement. When his Spiritual Strength completely refined the red energy, it would be the time of the Secret Art, the Soul Refinement.

Just like that, time passed bit by bit. During this time, the people from the sword faction walked out of their Swordheart Hall and looked at Ye Xingchen.

Ye Xingchen's current condition was extremely unique. If he did not wake up soon enough, the red energy would most likely devour his soul, and if he woke up on his own, he would be able to successfully refine the red energy.

Just when there were still seven days until the Heavenly River Town competition, Ye Yu's condition suddenly worsened, reaching the point of imminent danger, and the Spring of Life no longer had any effect.

However, Ye Xingchen was still cultivating his secret technique in the War God's Space, he didn't know anything at all.

"Refine it. Success. I want to succeed." Ye Xingchen could not help but shout from the bottom of his heart as the Spiritual Strength crazily refined the red energy in his mind.

"Boom …" With a sound, Ye Xingchen's pitch-black eyes instantly opened, and shot out a ray of terrifying golden light. The red energy that was currently resisting inside his mind was instantly refined.

"Finally, my Small Success." Ye Xingchen took a deep breath and said softly, "Let's hurry up and see Yu Er."

The moment Ye Xingchen mastered the secret technique, Soul Refinement, he immediately rushed to Ye Yu's room. There were a lot of people in Ye Yu's room, including Ye Yuanshan, Ye Hu, Ye Bao and a few other young people.

Everyone thought that Ye Yu wouldn't be able to hold on until today, so they all came to see Ye Yu.

When Ye Xingchen arrived at Ye Yu's room, his eyes suddenly lit up, "Chener..."

Before he could finish speaking, Ye Xingchen had already walked to the front of Ye Yu's bed and helped her mother up. Then, he placed his hand on Ye Yu's pulse.

Ye Yu's current situation was simply too terrible. If Ye Xingchen had come out one day later, then Ye Yu would have been completely hopeless.

"Father, mother, and grandfather, don't worry. I will definitely save Yu Er, but I'm going to start saving my sister now. You two can leave for a while." Ye Xingchen turned and looked at everyone, his face revealing a look of seriousness as he said that with a low voice.

"Chener, how is it?" Ye Hu asked.

"Father, don't worry. I'm confident." Ye Xingchen's face exposed a smile, reassuring everyone.

This was the first time Ye Xingchen had used this technique since he had mastered it. However, in order to let his father and mother feel at ease, he only needed to say those words.

Everyone walked out of the room, leaving Ye Xingchen and Ye Xingchen behind.

"Yu Er, hang on, I will definitely save you." Ye Xingchen muttered to himself.

After that, Ye Xingchen activated Spiritual Strength, and slowly entered Ye Yu's body through his finger, he was controlling the Spiritual Strength to slowly approach Ye Yu's mind.

When he neared Ye Yu's mind, he sucked in a breath of cold air. Ye Yu's current state was even worse than what he had imagined, the black damaged soul was already extremely powerful.

Sensing that Ye Xingchen's Spiritual Strength was approaching, the black colored soul suddenly resisted intensely.

He knew that Ye Xingchen's Spiritual Strength had definitely come here to refine it, and it had resisted very fiercely.

Ye Xingchen, on the other hand, carefully controlled his Spiritual Strength.

"Hmph, who cares what you are? "I must refine you. You dare to absorb my sister's life essence in my sister's mind?" Ye Xingchen looked at the black soul and his heart was filled with anger.

Seeing Ye Xingchen's Spiritual Strength enter from the black soul area, Ye Xingchen silently circulated the secret Soul Refinement's chant in his heart.

"Soul Refinement..." Ye Xingchen muttered to himself, and then, a red energy began to separate from Ye Xingchen's Spiritual Strength, this red energy was constantly approaching the black soul.

As Ye Xingchen controlled the red energy, he also controlled the Spiritual Strength, afraid that the red energy would hurt his sister's soul.

As for the black soul, it seemed to feel a trace of fear as it constantly dodged and violently struggled.

"Continue the binding." Ye Xingchen suddenly increased the output of the Spiritual Strength, causing the red energy to explode, as though it was about to surround the black soul.

Although the black soul had been absorbing Ye Yu's life essence for the past few years and had almost completely recovered, it was still incomplete, so Ye Xingchen's secret technique, Soul Refinement, was the most suitable to deal with it.

Vaguely, he could feel the black soul screaming, but Ye Xingchen did not care, and continued to attack nonstop.

Just like this, the black soul and red energy stayed deadlocked for nearly two hours, and in the end, was still wrapped by the red energy. Then, it fused with Ye Xingchen's Spiritual Strength and was finally brought to Ye Xingchen's mind.

"Phew …" Ye Xingchen took a deep breath, "I've finally completed it. It's really scary, but not dangerous."

Looking at his sister who had turned better, a sweet smile appeared on Ye Xingchen's face. His damaged soul had already been captured by Ye Xingchen and was now completely fine. He would probably wake up after a while.

And at this time, in Ye Xingchen's mind, the black soul felt a sense of fear, and continuously tried to charge out, but the red energy tightly wrapped around it, causing it to return empty-handed.

"Hmph, I'll begin refining you now." Ye Xingchen suddenly channeled the secret technique Soul Refinement's chant, causing the red energy to surge and continuously corrode the black soul.

Time passed bit by bit, and another two hours had passed before Ye Xingchen finally completed refining the pellet.

The black soul had already disappeared completely and the red energy had once again fused into Ye Xingchen's Spiritual Strength.

"The Spiritual Strength has grown by a lot." Ye Xingchen could feel that after completing the refinement, his Spiritual Strength had actually risen from the late stage of the Postnatal Stage to the Peak of Lesser Heaven Stage, and was only one step away from entering the Congenital Stage.

After taking a deep breath, Ye Xingchen stood up and opened the door, calling everyone in.

"Chener, how is it?" Ye Hu asked anxiously, and the others all looked at Ye Xingchen anxiously.

But when they saw the smile on Ye Xingchen's face, they immediately knew that they had succeeded.

"Haha, I knew Chener would definitely succeed, hahaha." Ye Hu hugged Ye Xingchen and laughed out loud.
