Because in general, most of the formations arranged in this trial place are just barriers, in order to hide one's own aura, the purpose here is naturally self-evident!

After all, this trial place can be said to be a situation where fish and dragons are mixed together. Naturally, the monks in the world will also use some barriers to protect their own safety.

After all, in such a situation, if there is no barrier and you are in some special situations, such as being injured or breaking through the realm of cultivation, in this situation, if you take advantage of others, the serious consequences will naturally be self-evident!

This is exactly the situation now!

Chu Chen plans to refine elixirs, so he will naturally not be disturbed!

However, Chu Chen was not simply setting up the formation barrier. At least Yun Yanran had already seen some of the names!

With Chu Chen's construction, this world seemed to be vaguely different, and the key here was the intensity of spiritual energy!

"This? How could this happen? The spiritual energy between the world seems to be pouring towards this place!"

"How could this happen?"

"What formation barrier is this person setting up, and why can it produce such an effect!" At this moment, Yun Yanran was naturally shocked in his heart and couldn't help but mutter to himself!

Because she had already noticed that with the condensation of Chu Chen's formation, the spiritual energy of heaven and earth was attracted, which could be said to have greatly shocked Yun Yanran!

Spirit Gathering Array?

Suddenly, this thought came to her mind from the Taoist son of the Tianyu Palace. Obviously, in her opinion, what Chu Chen condensed seemed to be a spirit gathering array. As for the purpose of this, it was naturally to gather the spiritual energy between the world!

But Yun Yanran discovered that the matter here seemed to be not as simple as this, because according to Yun Yanran's understanding, the general spirit gathering array was far from reaching such a level, and even the speed of spiritual energy flowing in, Yun Yanran was extremely surprised!

Chu Chen, who was standing beside him, had a calm face at this point, as if there was no change at all. He saw all this in his eyes and continued to build this formation barrier. This process can be said to have taken a long time!

It was a full hour. During this period, Chu Chen was constantly building the formation barrier, and Yun Yanran on the side was naturally also surprised. The more he got to the back, Yun Yanran's face became more and more shocked!

Because with the improvement of Chu Chen's formation, Yun Yanran also realized that this barrier does not seem to be a spiritual gathering array. Because it gathered, it is not as simple as a single spiritual energy. There are other dirty energy, evil energy, blood energy... all these emerged towards this formation barrier!

Of course, this was completely beyond Yun Yanran's expectations. Even in the past few years of practice in the Tianyu Palace, this Taoist from the Tianyu Palace had never seen such a scene, and there was a strong sense of shock!

Of course, what makes Yun Yanran even more puzzled is what Chu Chen condenses for!

Feng Yan seemed extremely calm at this time, obviously not surprising. After all, Feng Yan had noticed this when he broke through the realm before. Feng Yan was also surprised at that time, but he didn't take it too seriously!

Moreover, at that time, after Chu Chen built such a formation barrier, it could be said that he was not only free from outsiders' disturbances, but even Feng Yan felt that in that barrier, it was also of great help to his own practice!

Of course, now that Feng Yan has seen such a situation again, he has not reacted much!

At this time, Chu Chen slowly breathed a sigh of relief after he completed the formation barrier!

In this way, it is also possible to hide its own aura in the barrier, and in this barrier, it is also very helpful to Chu Chen!

After all, this time, Chu Chen planned to refine all the spiritual medicines he had obtained in the past few days!

In this case, some special things are naturally needed, at least there is a great demand for the spiritual energy between the world!

After all, in fact, generally speaking, the elixirs refined by alchemists must be in the spiritual vein land!

Because refining elixirs requires not only elixir fire, but also elixir furnaces and herbs, but also a large amount of spiritual energy. It is enough to meet the needs of refining elixirs!

In the current situation, Chu Chen had already explored his spiritual sense before. It was obvious that there were no spiritual veins around him that Chu Chen needed. However, even so, there was no such spiritual vein. In fact, for Chu Chen, refining elixirs would not cause too much difficulty!

Since there is no spiritual vein, I will create one. The current formation barrier is like this. It is like a large spiritual gathering array, with spiritual energy constantly pouring into it from afar. Of course, there are some other evil spirits, blood energy... all kinds of existences in this spiritual energy!

In this way, it is infinitely close to a spiritual vein. Naturally, such a elixir is completely enough for Chu Chen!

At this time, the Taoist son of Tianyu Palace next to him, Yun Yanran was shocked at the beginning, and now that Chu Chen had completely constructed the formation barrier, he naturally saw from her experience that Chu Chen's thoughts came!

And this can be said to have made Yun Yanran even more shocked, and he couldn't even believe all this!

"You, have you built a spiritual vein used to refine elixirs?"

"How is this possible? How could you have such a means? In order to refine elixirs, you actually arranged such a formation to forcibly activate the spiritual energy of the heaven and earth and build a spiritual vein!"

"My God!" At this moment, Yun Yanran was completely shocked. His face was unchanged for a long time, and even came with an indescribable sense!

After all, Chu Chen's method was not as simple as Yun Yanran's imagination, but made Yun Yanran feel as if he was dreaming. He couldn't believe everything in front of him!
