Bang!

As soon as his feet were empty, Yi Chen fell down, and when he looked around, this was an underground space.

"The aura and yin here ......"

Yi Chen only felt that on one side, the yin qi was forcing through his bone marrow, and even a martial artist like him felt trembling in his bones.

On the other hand, it is the aura that is so strong that it makes him feel very comfortable, like a baby in the mother's amniotic fluid, the same, so comfortable.

He knew that he had found the problem, and that this was where all the oddities came from.

There is no outside light in this underground space, but the entire space emits a faint, soft white light.

The light source came from a small spring not far ahead.

It is a small natural spring with a diameter of just over one meter and less than two meters, and the crystal clear groundwater gushes out of the small spring like boiling water.

There was a trace of mist above Koizumi, and it was this mist that emitted a faint soft light. This is actually a natural aura, and the aura has condensed into a mist, to the extent that it is visible to the naked eye!

"Could this be the spiritual spring of heaven and earth recorded in the outer chapter of the Shennong Medical Sutra?"

Yi Chen was shocked in his heart, there was a side story in the Shennong Medical Sutra, which specifically recorded all kinds of strange things.

Once, Yi Chen regarded this outer story as a legend, a myth, or even a novel, but now, he has believed everything recorded in this outer story.

And in this outer chapter, there is one that talks about the spiritual spring of heaven and earth.

It is a spring produced by gathering the aura of heaven and earth, and the aura is mist, even visible to the naked eye. What's more, the aura in the best spiritual spring is even mixed with the spring water to form a liquid aura.

But whether it is a misty spiritual spring or a liquid spiritual spring.

The intensity of its heaven and earth aura is several times, or even dozens of times, that of ordinary places!

The benefits of this for the cultivation of martial artists are self-evident!

Even, the water of this spiritual spring, because it contains a large amount of heaven and earth aura. For ordinary people, it also has the effect of curing all diseases, which can be said to cure diseases and strengthen the body without diseases.

It's just that it is recorded in the Shennong Medical Scripture that the spiritual springs of heaven and earth are extremely rare, and it is said that it is difficult to find traces on the earth, and Yi Chen did not expect that he would actually encounter one.

Cultivating in such a place is even two or three times faster than in other places!

Near the spiritual spring, Yi Chen couldn't even feel the existence of that yin qi, and all of them were forced by the spiritual energy.

"But where is the source of that yin qi?"

Yi Chen was not carried away by the joy of discovering the spiritual spring, the most primitive and fundamental purpose of his trip was to get rid of that yin qi.

Otherwise, ordinary people in his house would not be able to come in at all, so how could he open a clinic here?

Yi Chen walked forward for another ten meters, only to see a black mist floating in the air in front of him. And below the black fog, there was a strange figure that he couldn't even read, and the aura in the spiritual spring over there turned into many silk threads, which were slowly swimming towards the figure below the black fog.

This looked like the figure under the black mist, which Yi Chen couldn't understand, was absorbing the aura in the spiritual spring.

"Could this be the formation recorded in the outer chapter of the Shennong Medical Sutra?"

Yi Chen stopped.

There is a general statement in the outer part of the Shennong Medical Sutra that specifically records strange things.

The essence of the so-called formation is actually the external manifestation required by the so-called trapped array, killing array, phantom array, spirit gathering array, teleportation array, and so on through the convergence, adjustment, and use of the structure of the five essences of energy, matter, soul, time, space, and so on.

In the Shennong Medical Scripture, the main interpretations of the formations and the characteristics of each main formation type are only recorded in general terms, but there is no specific arrangement of individual formations.

Yi Chen looked at the figure in front of him, it seemed to be the high-level sealing formation in the Trapped Array category.

He stopped, carefully observing the black air in front of him and the graphics on the ground.

Now it can be determined that all the yin qi is emitted from here, and this black qi floating in the air is actually the black qi that is visible to the naked eye when the yin qi is extremely strong.

"That's not right, the sealing formation is a relatively powerful formation, it won't only have so much energy, and it won't occupy such a small area. Could it be that this is just a broken formation in front of you? Or is it part of a larger formation? ”

In fact, some powerful formations, it is not completely arranged in one place, it can be divided into many parts, arranged in all corners of the earth, various positions, and then unified and echoed each other, becoming a powerful formation.

"But who exactly is it that has set up such a formation here? And it exudes such a strong cold aura, it looks like it is sealing something. ”

He didn't know who had laid out this formation, nor what was sealed inside.

However, what Yi Chen could be sure of was that this formation must have been a long time old, and this formation had already been somewhat damaged by itself.

Otherwise, Yi Chen wouldn't have been able to approach here so easily, and the cold aura here wouldn't have spread out.

And now, the yin qi that came out of this formation was really harmful.

The family of six who lived here before, as well as the three tenants who moved in later, all died because of the cold aura emitted by this formation.

Moreover, if this formation is not dismantled, Yi Chen will not be able to open a clinic here.

What worries Yi Chen even more is that this cold aura has spread out and harmed the people who originally lived here. And as time goes by, will this cold aura spread out even more, so that the people who live in this area will die because of it?

This is not only about whether he can open a clinic here, but also about the lives of hundreds of thousands of people in this area!

Therefore, no matter who arranged this sealing formation, who sealed it inside, and the intention of arranging the formation was good or bad. Will the yin qi here spread out and kill hundreds of thousands of people in this vicinity?

Yi Chen wants to destroy this formation, because, this risk, Yi Chen can't take it!

Once you figure it out, it's very simple.

Yi Chen returned to the bottom of the pit, picked up the shovel that fell with him, and returned here, looking at the strange shape on the ground, this is the foundation of this formation!

He already had a solution in his heart, that is, to dig up the foundation of this formation, the formation would naturally collapse, and the yin qi would naturally dissipate.

Syllable!

But when Yi Chen shoveled down, it was like shoveling on steel, making a clang, and Yi Chen saw that his shovel was crooked, but there was nothing on the ground.

What Yi Chen didn't expect was that a black light emitted from the ground, knocking Yi Chen flying more than ten meters away.
