The fiery red threads that drilled into his body and drilled out from his fingertips were the essence of fire that Huo Lao put in the purple gourd.

Lu Chen has been hanging the purple gourd on his waist, as long as he has free time, he will urge the little gluttonous to devour the essence of fire, and then use the Nine Dragons Proverb to refine it into his own dragon qi, I really didn't expect that the essence of fire in the purple gourd would come in handy at this moment!

He could have directly pulled the fire essence in the purple gourd and controlled it through the air to penetrate Yu Pei's body, but the power of the fire essence was not trivial. Although he didn't know how the Fire Essence was born, the Fire Essence was obviously more powerful than the Earth Fire Flame drawn by the Fire Pillar.

As long as a little fire essence can burn through Yu Pei's dantian and break Yu Pei's qi sea, it is precisely because of this that Lu Chen has to let the fire essence drill into his body first. Of course, the essence of fire seemed to be drilled into, but it was actually actively devoured by the little gluttony that he urged him. The essence of fire roamed around his dantian and meridians, contaminating his own true qi, so that he could control it more easily.

After the essence of fire was contaminated with his own breath and penetrated into Yu Pei's body, Lu Chen could control the essence of fire even if he only used his own true qi sense, but this was the first time he used the essence of fire to refine the cold qi that invaded the sea of other people's dantian qi. Like the Xuan Bing Cold Qi, the Essence of Fire is also a xenomorph energy that invades Yu Pei's body, and every step is extremely dangerous!

Lu Chen's expression was solemn, his mind moved slightly, and a misty and sacred and majestic dragon gate appeared at the center of his eyebrows, which was the dragon gate of knowing the sea. As soon as the Zhihai Dragon Gate appeared, it slowly opened, and through the Zhihai Dragon Gate, you could see the Zhihai behind the portal.

Immediately, a wisp of sea knowledge power escaped from the sea knowledge dragon gate like a tentacle, and probed into Yu Pei's body along his five fingers that were clinging to Yu Pei's lower abdomen.

Seeing that there was no lust in Lu Chen's eyes, Yu Pei didn't know that the reason why Lu Chen lifted her clothes was really out of necessity. Sensing this, Yu Pei's heart knotted open, and his eyes were firmly fixed on Lu Chen. Just when Lu Chen used the power of knowing the sea and slowly closed his eyes, Yu Pei's eyes were slightly stunned, she inexplicably felt that Lu Chen's eyes were extremely bright, like the brightest star in the night.

Under the investigation of the power of sea knowledge, Yu Pei's dantian was completely white, and the dark red sea of qi was completely frozen by the cold qi of Xuanbing, just like a ripe cherry wrapped in thin ice.

Seeing this scene, Lu Chen became more and more cautious, and the power of sea awareness and his own true qi went hand in hand, accurately and subtly controlling the essence of fire silk, and the essence of fire silk thread swam like a fire snake to approach the thin ice.

"I'm going to start refining the cold qi in your body, if you feel anything uncomfortable, you must tell me immediately. Before he started, Lu Chen closed his eyes and said a word of advice to Yu Pei. After all, this is refining the Xuan Bing cold qi in other people's bodies, which is different from refining one's own Xuan Bing cold qi.

Hearing this, Yu Pei responded weakly.

Lu Chen controlled the essence of fire silk threads to continue to swim, and the five essence silk threads of fire did not all rush towards Yu Pei's dantian frozen by Xuan Bing's cold air, but divided into three ways. Three of the Fire Essence Silk Threads rushed towards the sea of qi, and the remaining two parted ways and swam along Yu Pei's meridians to the soles of her feet, cutting off the source of the Xuan Bing Cold Qi.

At the same time, Yu Pei only felt that her feet were slightly warm, but her dantian qi was still unresponsive. However, she had already determined that Lu Chen could help her refine the cold qi that had invaded her body, otherwise her feet would not have a warm feeling.

Cutting off the root of Xuan Bing's cold qi, Yu Pei didn't squeak, obviously didn't feel anything unusual. However, Lu Chen was still very careful and did not rush forward. The three silk threads of the essence of fire that rushed towards the sea of qi also reacted, and the sound continued, the cold qi of Xuan Bing was a strange thing of the cold attribute, and the essence of fire was a strange thing of the fire attribute. The two things are born to restrain each other, and as soon as they meet, they don't need to do anything to tear them up and annihilate each other.

Seeing that Yu Pei still didn't squeak, Lu Chen let go of his hands and feet a little, and the essence of fire silk swam like a coil, surrounded by a sea of frozen qi.

Zizizi......

The root of the Xuan Bing cold qi was cut off, but the essence of fire was pouring into Yu Pei's body in a steady stream, and after a short time, the Xuan Bing cold qi was only left with a thin layer.

At this moment, the Fire Essence Silk Thread approached Yu Pei's Qi Sea, only one step away, Lu Chen's expression was solemn, and he carefully controlled the three Fire Essence Silk Threads to swim away, breaking the last layer of the blockade of Yu Pei's Qi Sea by Xuan Bing's cold qi.

Click-

There seemed to be a soft sound, and the thin ice formed by the Xuanbing cold qi cracked, and the essence of the fire silk thread swam up, completely refining the Xuanbing cold qi in an instant.

Yu Pei was aware, but still a little incredulous.

"You run the exercises. Lu Chendao still didn't open his eyes.

Yu Pei nodded heavily, without a trace of doubt about Lu Chen's words, and hurriedly used the exercises he had cultivated to urge the sea of qi. After a moment, surprise burst into her eyes, and she cheered, "I can use my true qi!"

Lu Chen breathed a sigh of relief and said, "You try to use your true qi to cut off the invasion of Xuan Bing's cold qi. ”

Yu Pei nodded again, and True Qi swam towards the soles of his feet instead of the Fire Essence Silk Thread to cut off the invasion of Xuan Bing's cold qi. Lu Chen sensed that Xuan Bing's cold qi no longer needed him to resist Yu Pei, and took advantage of the situation to withdraw the two fire essence silk threads.

With a bang, Yu Pei broke through the frost, but before her steps were raised, the whole person was like stepping on the air, and she pounced softly on Lu Chen's chest.

Lu Chen was defenseless, and was pounced on by Yu Pei, only to feel that there were two soft balls pressing on his chest.

"Senior Sister Yu, even if you want to repay him for saving his life, you don't have to promise him. Hu Meidie said with a smile. Yu Pei is obviously because the Xuanbing cold qi in his body has been refined by Lu Chen, and Yu Pei's legs have been invaded by the Xuanbing cold qi, and it will take a while to recuperate before returning to normal. As soon as the silver frost broke, she fell uncontrollably to Lu Chen.

All the women burst into laughter.

Although Yu Pei's face was blushing, he was not to be outdone, and said: "Wait a minute, when Senior Brother Chen helps you senior sisters refine the Xuanbing cold qi in your body, don't let your legs go weak when you see Senior Brother Chen, and fall into his arms." ”

Hearing this, all the women suddenly couldn't laugh, and their faces blushed one by one.

Lu Chen ignored the mutual teasing of the women of the congregation and said, "I'll help you go." ”

"I'm afraid not. Yu Pei shook his head.

Lu Chen was slightly stunned, and immediately said no more, one arm wrapped around Yu Pei's back, and the other arm passed through Yu Pei's knees, picked her up horizontally, and sent her outside the teaching stone.

Seeing that Lu Chen's eyes were always clear, Yu Pei also put away his shy look, and hurriedly used his true qi to regulate himself.

"What now?" After putting down Yu Pei, Lu Chen walked into the teaching stone room again, and asked with a glance at the women.

At this moment, it was not that he was unwilling to continue to help Qin Qi and the others refine the Xuanbing cold qi in their bodies, but Yu Pei's crisis was lifted, and the women had enough buffer time. Now there are two ways, one is that Lu Chen left the teaching stone room to find Elder Yan and Senior Sister Ling of the Jingtang. Second, he will continue to help the women refine the Xuanbing cold qi.

And when refining the cold qi of Xuan Bing, Lu Chen had to uncover the clothes of the women, revealing their lower abdomen, which would damage the reputation of the women. If Lu Chen did this in normal times, I am afraid that the women would unite to hunt him down to the ends of the earth. At this moment, the situation is special, so it is naturally a different matter, but Lu Chen still has to ask them to decide.

All the women looked at Qin Qi, Qin Qi thought for a moment and asked, "Do you have the ability to help all of us refine the Xuan Bing cold qi in our bodies?"

Lu Chen nodded slightly, there were still a lot of fire essences left in the purple gourd, which was enough to help him refine the Xuanbing cold qi in the bodies of the women.

"Then there's work. Seeing that Lu Chen was definitely down, Qin Qi was not ambiguous at all, and made a decision immediately. One, just like Lu Chen said, he went to find someone and rushed to others, which took time. And Qin Qi was not ten percent sure, at this moment, Elder Yan and Senior Sister Ling were in the scripture hall. If neither of them is there, even if Lu Chen leaves, it will be a delay.

Lu Chen nodded secretly, but he admired Qin Qi's decisiveness. After the Xuan Bing cold air broke out, Qin Qi was the only one among the women who did not mess with herself.

The women witnessed Lu Chen refining the Xuan Bing cold qi for Yu Pei, so they naturally had no opinion.

The invasion speed of the Xuanbing cold qi was inversely proportional to the strength of the women, and Lu Chen's eyes swept away, and at a glance he identified the next woman who urgently needed to refine the Xuanbing cold qi. He dodged over, intending to distract the woman in front of him before lifting the other's shirt.

"My surname is Yao, my name is Yao Hui, and you just open it. The woman bowed her head and said, looking ashamed.

Lu Chen was slightly stunned, his little trick was actually seen through by the other party in advance. He didn't say anything more, and lifted the corner of Yao Hui's skirt, revealing a snow-white lower abdomen, and his five fingers were pressed against it, and the essence of fire poured out from his fingertips, and penetrated into Yao Hui's body along with the power of knowing the sea.

After a while, there was a crisp sound, and Yao Hui broke out of the frost in response. With the experience of refining Xuan Bing's cold qi for Yu Pei, Lu Chen was ready to hurriedly support Yao Hui, not letting her really throw herself into his arms, and then carried her out of the teaching stone room.

......

Time passed slowly, one after another women were refined by Lu Chen with the help of the essence of fire to refine the cold qi in their bodies, I don't know how long it has been, a group of women are sitting outside the teaching stone room, and only Hu Meidie and Qin Qi are left in the teaching stone room.

After sending off a woman, Lu Chen walked into the teaching stone room. Seeing Lu Chen walking towards her, Hu Meidie hurriedly said, "You help Senior Sister Qin refine the Xuanbing cold qi first, and I can hold on for a while." Although Hu Meidie tried her best to restrain herself, her teeth still trembled, making her words tremble.

At this moment, the silver frost has covered Hu Meidie's ribs, and although Qin Qi's situation is not much different from Hu Meidie's, the expressions of the two are very different. Hu Meidie was extremely weak, her delicate body trembled involuntarily, while Qin Qi was gritting her teeth and insisting, and her body did not tremble at all.
