Lin Xiao dispersed the purple qi slightly, and then wrapped a small trace of black qi, completely isolating that trace of black qi from the rest of the black qi. Then Lin Xiao urged the Rootless Divine Spring contained in the purple qi to purify that trace of black qi.

The trace of black qi that the rootless divine spring in the purple qi had just come into contact with suddenly became active, as if it had encountered its favorite food, and it frantically rushed to that trace of black qi.

The trace of black qi was also frantically surging towards the Rootless Divine Spring, and the two began to fight each other in close combat, and the battlefield was in the wisp of purple qi controlled by Lin Xiao.

The Rootless Divine Spring seemed to be even more domineering than Lin Xiao had imagined, and as soon as it came into contact with that trace of black qi, the black qi quickly decreased, and turned into an incomparably pure battle qi.

A smile appeared on Lin Xiao's face, and at the same time, he began to continue to purify with purple qi wrapped in a small part of black qi.

Lin Xiao chose to take it step by step, the amount of black gas in each package was not too much, and only after the black gas in the package was completely purified into pure battle qi did Lin Xiao continue to purify the next time.

In the process of purification, Lin Xiao always controlled the purple qi to keep wandering in Shen Dong'er's meridians after enveloping a part of the black qi, which reduced the collision of the remaining black qi with the purple qi.

Lin Xiao's approach came from the famous tactics of a great man in his previous life: sports warfare.

Take the initiative to withdraw troops, concentrate forces, and annihilate the enemy's living forces; mobilize the enemy, annihilate them individually, and annihilate the enemy in the course of movement.

The smile on Lin Xiao's face made Ye Wuxian also breathe a sigh of relief. Looking at Shen Dong'er's calm face, Ye Wuxian's eyes unconsciously flashed with tenderness.

"According to the previous estimate, now the young master should have purified almost half of the evil energy in Sister Dong'er's body, don't have any accidents!"

Three days have passed in the blink of an eye, and outside the secret room, Mu Yurou is still sitting at the door as she did three days ago, with some worry on her face.

"Yurou, will I still bring you the same food here today as I did the previous two days?"

Just as Mu Yurou was worried about the situation inside, the red lady walked slowly towards the secret room.

"Well, I'll wait here for the young master. ”

Mu Yurou nodded, a smile on her face.

"It's rare that you think about him all the time, Xiaoxiao is really a blessing!"

The red lady walked up to Mu Yurou and sat down.

A touch of blush appeared on Mu Yurou's face, and even the red lady lost her mind for a moment with her shy appearance.

"I'm not just worried about the young master, well, I'm also worried about Sister Dong'er, and Brother Ye!"

Mu Yurou became darker and darker the more she depicted.

"Hehehehe, little girl, what are you shy in front of me! If you are worried, you are worried, and it is not a shameful thing!"

Seeing Mu Yurou's shy appearance, the red lady couldn't help but joke.

"Aunt Hong"

Mu Yurou's face turned even redder, and she was coquettish.

"Okay, okay, I won't talk about it!"

Mu Yurou's cute appearance makes the red lady, who is also a woman, not have the slightest immunity.

"Hey, I don't know what's going on inside!"

After laughing, the red lady couldn't help but be a little worried.

"Aunt Hong, don't worry! The young master will definitely be able to cure Sister Dong'er smoothly!"

Seeing the appearance of the red lady, Mu Yurou couldn't help but comfort her, but in fact, she was no less worried than the red lady!

As Mu Yurou guessed, in three days, Lin Xiao had already purified half of the black qi wrapped in Shen Dong'er's battle qi.

Lin Xiao's consumption in the past three days was huge, which could be seen from the fact that there was a third of the missing Qi Returning Pill in the secret room and Lin Xiao's already soaked robe.

Although Lin Xiao had only controlled a small trace of purple qi to purify Shen Dong'er's body, the control itself was a process of consumption.

Lin Xiao's purple qi was much purer than ordinary battle qi, which also caused the purple qi to recover much more difficult than the battle qi. In just three days, Lin Xiao had already taken nearly 100 Hui Qi Pills, and Ye Wuxian, who was on the side, opened his mouth wide, and finally could only sigh a pervert in his heart.

Lin Xiao slowly withdrew his right hand on Shen Dong's jade back and exhaled heavily.

"Okay?"

Ye Wuxian's eyes lit up.

"Where is it so fast, only half of it!"

Lin Xiao rolled her eyes.

"That's?"

Ye Wuxian was a little puzzled.

"That drop of rootless divine spring is gone!"

After three days of purification, the black qi in Shen Dong'er's battle qi had decreased, and that drop of rootless divine spring had finally been exhausted.

Shen Dong'er's eyes, which had been closed for three days, slowly opened, and when she saw Lin Xiao's completely soaked robe and his slightly pale face, her face showed a touch of emotion.

"Brother Lin, thank you! If you're tired, take a break!"

Before Shen Dong'er finished speaking, she suddenly covered her chest and screamed, and then Shen Dong'er was so soft that she rolled in pain on the bed.

"Dong'er!"

Ye Wuxian exclaimed, sat on the bed, hugged Shen Dong'er into his arms, and let her lean her back against her chest, while holding Shen Dong'er's arms waving wildly with both hands.

"Dong'er! How are you! Where are you unwell? Are you sick again?"

Ye Wuxian hugged Shen Dong'er desperately, full of anxiety and distress.

"It hurts!"

"Second brother, you should think of a way! Dong'er said that she was in pain!"

Listening to Shen Dong'er's screams, Ye Wuxian felt the pain of his heart being cut open by someone!

"Give me the Rootless Divine Spring!

After Lin Xiao finished speaking, without waiting for Ye Wuxian to react, he quickly snatched the Rootless Divine Spring from Ye Wuxian's right hand, and the purple qi in his hand frantically surged into the palm of his hand, pouring out two drops of the Rootless Divine Spring and dispersing them evenly in the purple qi, and then secretly Shen Dong'er's left shoulder, controlling a trace of purple qi pouring into Shen Dong'er's body.

"Big brother, quickly protect Dong'er's vital body as I told you before! Use a few more drops of rootless divine spring, and you must resist the erosion of those black qi!"

Lin Xiao quickly purified the black qi in Shen Dong'er's battle qi while shouting at Ye Wuxian, who was out of order.

Ye Wuxian suddenly reacted when he heard Lin Xiao's words.

Light blue battle qi poured out from Ye Wuxian's right palm, and Lin Xiao held the rootless divine spring in his left hand and poured about ten drops into Ye Wuxian's right palm.

Ye Wuxian followed what Lin Xiao said, scattered the ten drops of rootless divine spring in the battle qi, and then poured it into Shen Dong'er's body to protect Shen Dong'er's heart and lungs.

As Ye Wuxian's battle qi entered, Shen Dong'er's face gradually improved, and the screams in his mouth gradually turned into a tiny "shenyin".

Lin Xiao slowly breathed a sigh of relief, and continued to control the purple qi to wrap a part of the black qi for purification. With Ye Wuxian's protection, Lin Xiao gradually let go of his hands and feet, and the amount of black gas wrapped each time gradually increased.

Since in the later stage, the remaining black qi is a relatively stubborn part, so although the number of Lin Xiao's packages has increased each time, the speed has not increased much.

Those black qi seemed to know their fate, and began to resist frantically, and at the same time, they were constantly devouring Shen Dong'er's flesh and blood to replenish.

In addition to protecting Shen Dong'er's vital points, Ye Wuxian also tried his best to protect some other parts of Shen Dong'er's body, which also alleviated the strength of the black qi rebound to a certain extent.

Lin Xiao knew that the more important it was in the end, so he didn't dare to be careless, and slowly closed his eyes, Lin Xiao's divine sense was all focused on purifying the black qi to avoid the slightest accident.

Another day passed, and the remaining black qi in Shen Dong'er's body was reduced by one-third again. At this time, Lin Xiao didn't dare to take the Hui Qi Pill to replenish the purple qi, and the current situation seemed to be a very balanced state, Lin Xiao didn't dare to break it, so he could only grit his teeth and insist.

While Lin Xiao was carefully purifying those black qis, the battle qi in Shen Dong'er's body began to become uneasy.

"Dong'er, stay calm, don't rush the war qi!"

Lin Xiao felt that Shen Dong'er's mood suddenly fluctuated greatly, and couldn't help but shout loudly to make Shen Dong'er sober up.

But what Lin Xiao didn't expect was that his words had no effect at all, and Shen Dong'er's battle spirit was still scurrying around uneasily in his body.

"Dong'er! If you continue like this, the three of us will be in danger! Hurry up and stop!"

Shen Dong'er's battle qi still had no tendency to stop, and when Lin Xiao was anxious, another light blue battle qi surged in, suppressing Shen Dong'er's restless battle qi.

"Big brother, I'm glad to have you!

Lin Xiao slowly breathed a sigh of relief, closed his eyes tightly and concentrated on purifying the remaining black qi.

"Hehe! It's okay, I'm still worried that my battle qi will be bad if it goes in!"

Ye Wuxian's voice was a little weak, presumably his consumption was more serious after this day.

Lin Xiao didn't say more, controlling that trace of purple qi and continuing to purify.

Another two days passed, and feeling that the last trace of black qi was gone, Lin Xiao's frowning brows finally fully relaxed.

Lin Xiao did not withdraw his purple qi at this time, and the good deeds were done to the end, anyway, the rootless divine spring in the purple qi had not been used up yet, so he simply took this opportunity to purify the battle qi in Shen Dong'er's body.

Lin Xiao controlled the purple qi and began to swim in Shen Dong'er's meridians, and Ye Wuxian's battle qi also retreated in time.

An hour later, Lin Xiao completely purified the battle qi in Shen Dong'er's body. At this moment, although the purity of Shen Dong'er's battle qi was not as good as Lin Xiao's purple qi, it was many times stronger than other people's battle qi!

Slowly retracting the purple qi, Lin Xiao opened his closed eyes.

"How do you feel?"

Lin Xiao looked at Shen Dong'er and asked with a smile.

Shen Dong'er slowly opened her eyes, but her eyes were not full of joy at all, but were full of sadness and pain.

"Why do you do this, why?"

Shen Dong'er's performance made Lin Xiao a little confused.

"Why do you want me to suffer for the rest of my life? Why! Brother Ye!"

Shen Dong'er let out a sad cry, turned around and hugged Ye Wuxian into his arms.

Lin Xiao was stunned in her heart, and suddenly looked down at Ye Wuxian in Shen Dong'er's arms, and her face suddenly turned extremely pale!
