Ghost Sword Valley is a forbidden area. The sect has always emphasized that it should not be approached. It is very dangerous inside. No one of the monks who went deep inside had ever come out, and Wu Yan never wanted to go in, but the powerful hurricane wrapped Wu Yan in like this. Wu Yan could only sigh that he was unlucky. While there was no fog, Wu Yan also crushed a trigger jade slip, but the jade slip was useless here at all, which disappointed Wu Yan very much.

Fortunately, Wu Yan obtained the property of the other two, with five trigger jade slips in total, so Wu Yan dared to try to use one. Wu Yan has also observed it carefully these days, but there was no sign of finding a way out. Moreover, the Ghost Sword Valley is very large, and Wu Yan didn't know how to go.

As Wu Yan kept walking in the Ghost Sword Valley, Wu Yan felt that the yin energy here was very heavy. Although it could not be called the extreme yin place, it was almost the same. Seeing that he could not find it, Wu Yan found a huge rock, opened a hole upward from the bottom of the huge rock, opened a small space inside the huge rock, and made a hidden cover to cover the outside. Wu Yan entered the fairy bead in the cave and began to meditate and rest.

The spiritual energy in the fairy beads is really rare. The growth rate of the spiritual medicines in the fairy beads has basically stopped. Only the spiritual energy at the center of the fairy beads has some spiritual energy, but for these spiritual medicines, it has no effect at all, and this spiritual energy does not have much effect on Wu Yan's cultivation.

Fortunately, Wu Yan carried a lot of spirit stones, but I don’t know how long he could stay in this place, so Wu Yan didn’t dare to crush the spirit stones and sprinkle them into the fairy beads. Even Old Man Huang looked a little depressed because of his scarcity of spiritual energy. His two little hands kept holding a medium-grade spirit stone and kept wandering in front of Wu Yan.

Wu Yan planned to stay in this stone chamber for a while before talking. He didn't know if there would be monsters here in Ghost Sword Valley to chase them. Anyway, Wu Yan planned to stare blankly in the stone chamber.

A month later, the earth armor ant placed outside Wu Yan began to get irritable and restless. Although there was no dangerous warning, Wu Yan still came out of the fairy beads and walked outside. Wu Yan retrieved the earth armor ant and saw that the earth armor ant was very depressed, and the eyes were not shining at all, as if it was eroded by the yin energy and its strength was greatly damaged.

These are the few remaining earth armor ants that Wu Yan has. He is still needed at the critical moment. Although Wu Yan has started feeding black butterfly ants, these black butterfly ants have not hatched for a long time, and the environment in Ghost Sword Valley is not good, which is not conducive to the growth of black butterfly ants. Wu Yan put all these black butterfly ants into the pet bag. Wu Yan took out another earth armor ants and began to alert outside.

Time passed quickly. Wu Yan stayed in the stone chamber for half a year and was not besieged by monsters. This surprised Wu Yan and felt it was very reasonable. After all, except for the fog in the Ghost Sword Valley, Wu Yan did not find any monsters in the remaining time.

In the past six months, Wu Yan also reorganized the skills he had learned before and adjusted his condition to the best state. Wu Yan planned to go outside and check it out. His cultivation level could not be increased much after staying in the immortal bead. He might find a way back when he went out.

In this way, Wu Yan started to explore around the surroundings with the huge rock as the center. When the fog was about to come, Wu Yan found a place to hide, sometimes hiding in the fairy beads. However, after more than ten days, Wu Yan found nothing but found a few good pieces of refining materials.

In order to get out of the Ghost Sword Valley, Wu Yan groped in one direction, but within a month, Wu Yan found that he was lost and could not figure out the direction he had chosen.

Could it be that I just stayed in the Ghost Sword Valley until I died? Wu Yan was very unwilling to accept it. After thinking for a long time, Wu Yan decided to practice "Tianyin Gong". Although this technique is not suitable for him, this place has no spiritual energy, and staying in this place for a long time is very dangerous. Maybe only by practicing this technique can you adapt to this place.

After making sure to pay attention, Wu Yan found a place with the heaviest yin energy and began to practice "Tianyin Gong". Although this technique is a mid-level heaven-level exercise, Wu Yan felt it was difficult at first. Although Wu Yan was already a Jindan cultivator, this technique was still quite different from ordinary exercises. It took Wu Yan more than six months to practice Tianyin Gong to the ninth level of Qi Refining. However, at this time, Wu Yan gradually understood some of the cultivation tips of Tianyin Gong and his practice began to go smoothly.

After practicing the Tianyin Kung Fu, Wu Yan clearly felt that the Ghost Sword Valley had less constraints on him. Although it was less, it was more safe in the Ghost Sword Valley. So Wu Yan stopped walking and practiced the Tianyin Kung Fu hard.

Time passed quickly, and in a blink of an eye, three years passed. Wu Yan relied on a large amount of elixirs and the extremely heavy yin energy of the Ghost Sword Valley to cultivate the Tianyin Gong to the later stage of foundation building. When he practiced forward, Wu Yan encountered a bottle without any progress.

However, at the later stage of foundation building, Wu Yan was walking outside and the automatic loss of true energy in his body was reduced by a part of it. He could hold on to two more incense sticks before he practiced the Tianyin Technique. His body felt that it was not that heavy, and he also lost a part of the true energy when he walked.

What made Wu Yan happy was that Wu Yan finally killed five monsters in the fog. The main reason was that this monster was too fast and was extremely difficult to detect. This was also something Wu Yan finally killed. The five monsters were all gray in shape, with a pair of flesh wings, and a row of neat fangs on their mouths, and were also highly poisonous monsters. Wu Yan called this monster the fog poisonous beast.

These third-level monsters actually have inner elixirs. Although they are not big, the inner elixirs are all transparent small beads, which surprised Wu Yan very much.

On that day, Wu Yan was walking outside. Suddenly, the originally deadly Ghost Sword Valley suddenly began to sound like a wind. Wu Yan immediately stood on a small mountain and carefully observed the surroundings. He saw that a black vortex tearing apart from the air from a distance ahead of him, causing the surrounding air to flow. The originally deadly Ghost Sword Valley finally changed a little.

This situation lasted for more than a month, and Wu Yan found that a stream of hurricanes gathered from around the black vortex, and a lot of debris continued to fall in the air. The strength of the hurricane seemed to be getting smaller and smaller in the Ghost Sword Valley, but it was not something Wu Yan could resist. Seeing that the hurricane was about to reach his place, Wu Yan hid. Not long after, the hurricane left Wu Yan's place, leaving a mess on the ground. After this lasted for a few days, Wu Yan walked out of the cave where he was hiding. Not long after he walked out of the cave, Wu Yan discovered something that surprised Wu Yan.

It turned out that there was a dead fog poisonous beast next to a rock. The fog poisonous beast was quite big. Wu Yan immediately took away the fog poisonous beast's corpse. As Wu Yan kept walking, Wu Yan found dozens of fog poisonous beast's corpses, all of which were collected by Wu Yan.

In this way, Wu Yan's walking range became larger. Whenever he saw a hurricane coming or a fog came out, Wu Yan would hide it. As long as the outside environment improved, Wu Yan would come out to search for the corpses of the fog-poisoned beast.

What surprised Wu Yan the most was that Wu Yan actually found the corpses of two fog poisonous beasts that did not die. This was very surprising to Wu Yan. Both of these fog poisonous beasts were very large, several times larger than the fog poisonous beasts he hunted. They were both seriously injured and could not move around. They were also very poor in spirit. They probably had no good environment to recover and would definitely die within a few days.

Wu Yan quickly took away the two fog poisonous beasts and found a hidden underground cave. Wu Yan was preparing to study the living fog poisonous beasts.
