Tian Xu's body was full of spiritual energy, and he didn't want to go down the mountain honestly in the usual way, so he used the suspension formation used in the Tianshan Mountains, and his body floated in the air, heading into the distance.

Along the way, he constantly tried to change the altitude, speed, uphill, and downhill of the flight, and experienced the intuitive feeling of this flight state. He didn't have to spare his aura at this time, he let go of his hands and feet to experience, practice, and improve the problems in his flying formation. When he was in the Tianshan Mountains, his flying formation was very simple, and in order to escape with inconvenience, he had to fly continuously for a whole night, traveling nearly 100 kilometers, and the spiritual energy consumption in his body was very serious, so he could only use qi replenishing pills to maintain his flight.

At that time, he wanted to improve his flying formation, but he never had time to do it. At this time, he finally had a chance, and there was enough aura for him to waste, so he let go of his hands and feet to do it.

He had the experience of experimenting with improving swimming speed in the water, and at this time he used it in flight, but there are many things that can be used for reference, so that the improvement of the flight formation this time is twice the result with half the effort and extremely efficient.

He didn't worry about leaving the purple smoke too far, but just circled and flew around the peak where the cave was located, and the circle became bigger and bigger, but the straight-line distance from the cave never exceeded 5 kilometers. In this way, I flew for nearly two hours in a row, and the excess aura in my body was consumed, and the efficiency of flying has also improved a lot, at least it is no longer a big burden, but it consumes a little more than walking with my legs open, and it has basically reached the level where I can travel daily.

To his dissatisfaction, the speed of the flight was not too fast, it could only reach more than 100 kilometers per hour, a little faster than he could run on the road, and a little faster than he could dive in the water. Of course, if he explodes with all his strength, the speed will be much faster, but if you want to be faster, the aura consumption will have to be greatly increased, but if it is used to fight or escape, it is still acceptable.

Another disadvantage of his flight is that he is not agile enough, far less than in the water or on the ground, and if he is in a combat situation, he does not seem to have much advantage in the air. But he didn't have any grievances, the red-maned giant wolf he had seen and Aunt Zhou seemed to have the same problem when flying.

Flying is no longer a particularly difficult thing for him now, and after this novelty, he loses interest in playing, and he is bent on finding prey.

During the flight just now, he had also found some small animals, but the largest was a small muntjac, at best, it was only a dozen catties, and this weight made him worry that he would not be able to bear that Xuanyu Creation Pill. He had no choice but to follow the stale scent of a herd of wild boars down a valley. The range of the wild boar will not be too large, and there is still hope that he will find this group of wild boars.

After chasing two kilometers, he accidentally spotted a takin. It was an adult male takin, but it was able to meet his needs for experimentation. The number of this animal is very rare, and it is a national first-class protected animal, so he can't care about it at this time.

The takin is a very hot-tempered animal, and the adult male takin is even wilder than the wild boar. However, this was difficult for Tian Xu, he easily subdued this big guy with his aura, and successfully fed it the Xuanyu Creation Pill.

After the medicinal effect of the Xuanyu Creation Pill began to exert itself, the takin calmed down, and under the effect of this high-grade all-powerful pill, it couldn't refuse that comfortable feeling at all.

It took Tian Xu more than twenty minutes to successfully extract the energy of the Xuanyu Creation Pill from the takin's body again, so that this guy's wonderful feeling came to an end, and it roared in a low voice of dissatisfaction, and its violent temper was about to attack. Tian Xu fed a Xiaoyao Pill into its mouth, which quieted the big guy again. The takin risked his life to help him complete the experiment, and some compensation was due.

Tian Xu didn't know if this Xiaoyao Pill would be able to open the spiritual wisdom of this takin and let it start cultivating, but the opportunity was given to it, and the rest of the things could only be grasped by itself. A Xiaoyao Pill is the limit that Tian Xu can give, even if he loses again, he is reluctant to take another Xuanyu Creation Pill to feed the cow.

The ban on the takin was lifted, and Tian Xu turned around and returned to the cave. The takin followed the direction he had left for a long distance, quite reluctantly. However, Tian Xu didn't have time to care about this guy, he had to rush back to the cave immediately to treat Ziyan.

It took him two or three hours to toss and turn, and when he returned to the cave, it was almost dawn. Ziyan was still sleeping there, Tian Xu greeted her, and she still didn't react.

Tian Xu didn't care about this, he was in a very good mood. Now that she had experimented with the method of extracting the Xuanyu Creation Pill from her body, the next step was to get the remaining Xuanyu Creation Pill out of Ziyan's body, and then she could regain consciousness.

Aunt Zhou has been gone for a week, he has been frightened for a week, and now he has finally found a solution to the problem, and the heart that has been hanging there suddenly relaxes, making him feel deeply tired again. Only then did he really understand what Zhou Aiping said, mental fatigue is the meaning of the deepest level of fatigue. But despite his fatigue, he didn't want to rest. He wanted to extract the Xuanyu Creation Pill from Ziyan's body in one go, so that she would no longer have to be bullied by the nine-petal jade lotus who suffered from obsessive-compulsive disorder.

However, he couldn't do it immediately, because just now when he was trying to extract the Xuanyu Creation Pill from the takin's body, he had absorbed a large amount of spiritual energy, and once again absorbed it a little overwhelmed, if he extracted the Xuanyu Creation Pill for the purple smoke now, there would be no place to absorb it.

It's not that these auras are wasted, but because these auras that have just been extracted from the Xuanyu Creation Pill, although they have been refined by his Danhuo, there are still some nine-petal jade lotus and Tianxuanguo wills more or less. After he absorbs it, he has to spend some effort to use the Pure Heart Mantra to completely subdue these spiritual energy, if he doesn't absorb it and let these spiritual energy escape, it doesn't matter if the number is less, if the number is too much, he doesn't know if there will be any accidents.

It stands to reason that the possibility of an accident is not great, but Tian Xu does not dare to take risks. The first thing he needed to do now was to release a part of the aura in his body.

He first used his aura to give Ziyan a remote-controlled full body massage, and then cleaned up her body. Then he used the method of aura heating to boil porridge for Ziyan, and finally ran outside, used the aura remote control to collect a lot of flowers, and made a wreath for Ziyan. After working for more than an hour, when Tian Xu looked at his aura again, he was disappointed to find that less than one-fifth of the aura had been consumed, which was definitely not good.
