What Xia Rufei wants to take is naturally the Time Array Flag. Song Wei's cultivation level has reached the 4th level of Qi training, and his mental power cultivation has even reached the Lingji stage. Therefore, when Ling Qingxue is practicing, he must use the Time Array Flag, otherwise it will be difficult to catch up with Song Wei's progress.

Therefore, Xia Rufei did not intend to conceal the existence of the time array flag from Ling Qingxue.

After he left the bedroom and walked around the next room, he took out the time array flag from the space to cultivate the heart-condensing grass, the time array flag was temporarily idle.

Xia Rufei returned to the bedroom with the entire array flag.

When Song Wei saw the quaint small flag in Xia Ruofei's hand, she asked curiously: "Ruofei, what is this?"

Xia Ruofei smiled and said, "Last time you saw the magical power of a monk, and today I will show you a more magical ability..."

Then Xia Rufei didn't say it, and waved his hand and threw the array flag out. Each flag fell accurately at the position they should be. Now Xia Rufei used the array flag to set up the array, which was almost done with just one thought, and he was quite skillful.

Then, Xia Rufei held Ling Qingxue's hand and walked towards the time formation.

Ling Qingxue was still a little confused and didn't know what these small flags were doing.

As she walked towards the formation, Xia Rufei waved her hand, and a tissue box on the bedside table flew out of thin air and fell into his hand.

Then, Xia Rufei took Ling Qingxue's tenderness and stepped into the time formation with one foot. At the same time, he threw the tissue box upwards...

After entering the formation, Ling Qingxue did not feel the change in the flow rate of time. In fact, compared with the people in the formation, the flow rate of time is naturally one to one.

Xia Ruofei smiled and pointed, "Look!"

Ling Qingxue looked in the direction of Xia Rufei's finger. She saw that the tissue box seemed to solidify in the air, and she immediately opened her eyes in surprise.

However, Xia Rufei could even take pictures from a distance, and it should not be difficult to control a small tissue box in a suspended state. This is what Ling Qingxue thought at this time.

Xia Rufei also guessed Ling Qingxue’s thoughts and said with a smile: “I did nothing!”

"How is that possible!" Ling Qingxue shouted in disbelief, and she stared at the tissue box tightly, feeling unbelievable.

Xia Ruofei smiled and said, "Put your imagination, and observe carefully..."

Ling Qingxue looked at the tissue box with a puzzled look on her face. After careful observation, she found that it was not hanging motionlessly, but falling at an extremely slow speed. A flash of inspiration suddenly appeared in her mind.

"Time!" Ling Qingxue said in shock, "Ruofei, you can actually control the flow rate of time!"

Xia Ruofei smiled and said, "It's not me, but these array flags..."

Ling Qingxue looked at the flag forming the formation and couldn't help but exclaim: "The flag that looks inconspicuous! It can actually control the flow rate of time... This is really amazing!"

Xia Rufei smiled and said, "This time array flag is naturally created by cultivators. You will know in the future that formations are also a very important category in cultivation, especially formations such as time and space, which are quite difficult. Anyway, my current cultivation level is far from touching advanced rules such as time, let alone creating a formation flag that low-level cultivators can also use!"

Ling Qingxue pursed her lips and asked, "Ruofei, how many times can this formation change the time flow rate?"

Xia Ruofei said: "The limit level is about 100 times, which has a lot to do with the range of the formation. The larger the range, the worse the effect. For the current formation, it will be almost seventy or eighty times faster! So, after one second outside, the formation will be almost one or two minutes."

When the two entered the formation, the tissue box had basically just fallen from the highest point. The process of landing outside was about two to three seconds, and in the time formation, it looked like four or five minutes.

So after the two of them talked for a while, the tissue box fell a little bit. The whole process was quite slow. If you didn't look carefully, you wouldn't even notice its position change.

Ling Qingxue calculated quickly and cheered: "So, if we have been practicing in the time formation, wouldn't we be able to achieve seventy or eighty times more efficiently?"

Xia Rufei smiled and said, "Theory is this, but there are two problems. One is that the time we experience is actually synchronized with the formation. If you stay in the formation for a long time, you will age very quickly compared to the outside world. For example, if you stay in the formation for a year, you stay in the formation. In fact, you have spent seventy or eighty years. When you leave the formation, your relatives and friends may not have changed much, and you are already a centenarian... Of course, this is an extreme situation. How can you stay in this small formation for seventy or eighty years?"

Ling Qingxue nodded and asked, "You just mentioned two questions, so what else is there?"

Xia Rufei said: "The second problem is that even if you don't mind staying in this small formation for a long time, you cannot continue to practice. Your spirit will not be able to stand it first, and people always need to eat, drink, defecate, right? Also, what I have always emphasized that practice requires moderate tension, just like rubber bands. If you are always tight, the final result will definitely be broken."

Speaking of this, Xia Rufei said: "So, I do not recommend using the time formation for a long time. Of course, it is harmless to take it out and use it when practicing!"

"I understand..." Ling Qingxue was as good as a stream of good deeds.

Xia Rufei smiled and said, "Okay, you can practice in this formation first! I'll prepare dinner for you. Considering the problem of the difference in time flow rate, you feel a little tired when practicing in the formation, so you have to stop and rest, or feel that your control of true qi is accurate enough, so you can just leave the formation and go downstairs to walk, in short…"

"Haughtiness means not achieving success!" Ling Qingxue smiled and continued Xia Ruofei's words.

Xia Ruofei touched Ling Qingxue's hair pamperedly and said, "Congratulations! You have learned to answer quickly!"

"Hate! Don't touch my head!" Ling Qingxue said coquettishly, "He is not your pet!"

Xia Ruofei laughed and said, "Okay, you practice! Remember what I said to you!"

After saying that, Xia Rufei took a step and left the range of the formation.

When Ling Qingxue was about to sit cross-legged and practice, she suddenly saw Xia Rufei, who had just left the formation, not walking out, but maintaining a walking posture, as if he had been casting a fixed posture.

Ling Qingxue was stunned for a moment. At first, she didn't know where Xia Rufei was making a fuss, but soon she realized that this was caused by the difference in time flow rates inside and outside. After Xia Rufei left the formation, the space time flow rate he was in was seventy or eighty times slower than inside the formation, so it looked like a slow motion shot of a high-speed camera.

Ling Qingxue mischievously grimaced at Xia Rufei's almost frozen back, and then grinned and waved her fists a few times at Xia Rufei. However, soon she felt that her actions became a little childish and couldn't help but burst into laughter with embarrassment.

Originally, Ling Qingxue wanted to wait until Xia Rufei left the door before starting to practice, but no matter how quick Xia Rufei was, it would take at least ten or twenty seconds to walk from here to the door. It would take more than half an hour to calculate the formation, and Ling Qingxue could not wait stupidly.

She thought about it, and simply sat down cross-legged with her back to Xia Rufei, quickly eliminated her distracting thoughts and began to enter the state of cultivation.

Xia Rufei prepared dinner downstairs. When he went upstairs again, the outside world had almost been hours, which means that almost three days and three nights had passed in the space.

When he entered the house, Ling Qingxue was still in the formation and practicing cross-leggedly.

Of course, she can't stay in the formation for three days and three nights without eating or drinking. Even if she can carry it for three days without eating or drinking water, she can't stay out of the toilet for three days!

So in fact, Ling Qingxue also practiced for a few hours, then left the formation to rest for a while, and then ate some food, went to the toilet, etc.

Of course, she has practiced for at least twenty hours this time.

Because she was facing away from Xia Rufei, Ling Qingxue did not notice his arrival. It was not until Xia Rufei stepped into the formation that she felt something and slowly opened her eyes.

"Ruofei!" Ling Qingxue greeted with a smile.

Xia Ruofei asked with a smile: "Do you feel like you haven't seen me for several days? I miss you very much? Actually, I've just left for an hour..."

Ling Qingxue blushed and said, "I don't miss you! Now I will practice wholeheartedly, and I want to cut off the world..."

"I'll go... I think you'd better stop practicing!" Xia Ruofei said, "If you continue practicing, you won't be a nun! Then I'll lose a lot. Such a beautiful wife has led her to go astray..."

"Go to die!" Ling Qingxue stamped her feet in anger.

Xia Ruofei laughed and said, "No kidding, Qingxue, this time the practice is effective, right?"

"Well! Check my results?" Ling Qingxue asked confidently.

"Don't worry, let's go downstairs to have dinner first." Xia Ruofei said with a smile, "Eating is bigger than that. Let's talk about anything after you have something to do!"

"Okay!" Ling Qingxue said, "As soon as you said that, I feel quite hungry..."

Xia Rufei was speechless and asked, "You can't have eaten yet?"

Ling Qingxue said embarrassedly: "When you are hungry, you can eat some snacks..."

"Not this is allowed next time!" Xia Ruofei said with heartache, "Otherwise I really won't teach you how to practice!"

"I understand..." Ling Qingxue lowered her head and said, then she put her arms around Xia Rufei's arm and said, "Stop criticizing me, let's go to have a meal!"

Xia Rufei was afraid that Ling Qingxue would be starved, so he didn't bother to talk about her anymore, so he pulled her out of the formation.

Xia Rufei waved his hand, put away the formation flag, and then led Ling Qingxue's men downstairs to have dinner.

Considering that Ling Qingxue had been practicing in the formation for so long, Xia Rufei was not in a hurry to take Ling Qingxue to practice after dinner, but instead took her for a walk in the farm. The two walked together for a long time, and even went to the orchard in the back mountain for a walk. They didn't return to the villa until after nine o'clock in the evening.

Xia Rufei asked Ling Qingxue to practice once as usual, and he used his mental power to observe Ling Qingxue's state.

The result was naturally very satisfied with Xia Rufei. Compared with the evening, Ling Qingxue's control of true qi is more in place. It has to be said that talent is really an extremely important factor in cultivation. Ling Qingxue is indeed making rapid progress in cultivation.

Since all the prerequisites were met and Ling Qingxue was extremely looking forward to it, Xia Rufei naturally would not delay any longer and decided to try his first joint training tonight.

Ling Qingxue naturally cheered and urged Xia Rufei to take out the time array flag.

Xia Rufei said, "No more use of the array flag. We are just a preliminary attempt tonight. The purpose is to give you an intuitive feeling about the two of you practicing together. Moreover, you have practiced for more than 20 hours before, so it is not suitable for practicing for a long time at night."

"Oh! I understand..." Ling Qingxue said, "Then let's start!"

Xia Rufei nodded and said, "Remember the key points I mentioned before. The key is that the two should be as synchronized as possible. As long as you do this, we will be more than half of the success. With your current control of true energy, as long as you don't panic, you will have no problem completing a successful joint training."

"Yes!" Ling Qingxue nodded heavily.

The two sat down with their palms against each other, and soon distracted from distracting thoughts and began to practice together for the first time.

In fact, when practicing together, the exercise route is the same as when practicing alone, but the difference is that it controls the true energy of two people.

The true qi of the two people is combined together. Now one of them circulates in the meridians once, then enters the meridians of the other person and walks around the same route. Only in this whole process can one complete a "big circumference".

The difficulty of this is undoubtedly the synchronization of the true qi, and when exchanging the control of the true qi, you must cooperate very well, otherwise the true qi may lose control.

Xia Rufei was already familiar with the way. He quickly adjusted his true qi to the same frequency as Ling Qingxue's true qi, and then slowly entered Ling Qingxue's body.

Ling Qingxue controlled his true qi to merge with Xia Rufei's true qi, and then began to slowly run along the meridians.

Originally, when Ling Qingxue was practicing alone, she had already managed to control the true qi easily, but with Xia Rufei's true qi, she suddenly felt the difficulty doubled, as if she was a little careless, the true qi would lose control and run wild.

The fused true qi slowly runs in Ling Qingxue's body. Without passing through one place, it will bring great benefits to Ling Qingxue's meridians. After passing through the dantian, a new ray of true qi suddenly emerged from Ling Qingxue's dantian, which was many times faster than practicing alone.

Finally, Ling Qingxue controlled the true energy back to the other arm meridian, and then carefully sent it into Xia Rufei's body through the palm of his hand.

Xia Ruofei took over the control of the true qi very steadily. It was precisely because of his excellent cooperation that the two were almost seamlessly connected.

Next, the true qi flowed much smoother, and the speed was much faster than that in Ling Qingxue's body. Soon it ran in Xia Rufei's body for a week, and finally returned to Ling Qingxue's body through Xia Rufei's palm.

This is the completion of a great cycle.

Of course, compared to Ling Qingxue, the benefits Xia Rufei has obtained are minimal.

The two exchanged control of true qi with each other, allowing the combined true qi to wander between the two, and Ling Qingxue's control of true qi became more and more convenient...
