I am doing meritorious deeds in Liaozhai

After chatting with the senior sister and relaxing for a while, Song Yushan continued to practice in seclusion.

The difficulty of transitioning from a single Five Elements spell to a double Five Elements spell has increased significantly.

When learning the yin and yang invisibility technique, Song Yushan found it a bit difficult.

But after experiencing the usefulness of the invisibility talisman, Song Yushan couldn't let go of the yin and yang invisibility technique.

Yin Yang invisibility is more effective than the invisibility charm.

The physical body can be hidden from the beginning to the small level, and the soul can be hidden from the great level to the perfection level.

In other words, using the Yin-Yang invisibility technique, not only the naked eye can't see her, but ghosts can't see her either.

In the middle stage of the Concentrated Consciousness Realm, the soul can be separated from the body, and it can also be used to hide the soul.

This effect cannot be replaced by the current magical powers of the Heritage Institute.

So even if it is difficult to learn, Song Yushan has to grit his teeth and learn it.

After studying this for three years, when the Yin-Yang Invisibility Technique was perfected, Song Yushan passed the third-level exam in all four of Song Yushan's alchemy weapon arrays in the examination room, and his weapons and martial arts skills reached the tenth level, and his cultivation level also advanced to the level of Concentration. In the middle stage of the realm, you can leave your body for a short period of time at night.

Song Yushan was about to receive the inheritance of the Five Elements Escape Technique. When she was continuing to learn, she received a letter from Xiao Yi riding a pony across several counties.

"The number of male water ghosts in Qinglong River has increased sharply. They all died after their essence was sucked out and their flesh and blood were eaten. Some ghosts even lost their souls. According to the surviving water ghosts, the murderer was a green snake demon with white spots on his forehead. Suspected to be Qingying."

Song Yushan frowned when he saw the word "Qingying".

Memories from years ago came to mind.

Her mentor, Granny Hua, also dreamed of being successful in cultivation, accompanying her demon pet, and traveling to the end of the world holding a stick.

However, because he dissuaded his demon pet from falling in love with a mortal, at the critical stage of advancement, he was hurt by a trusted demon pet, his lifespan was shortened, and he could no longer make any progress in his cultivation.

Finally, he left the school and spent the rest of his life in a remote small county.

When Granny Hua was unconscious before her death, she was still chanting the name "Qingying".

Song Yushan found out Qingying's appearance from her mother-in-law's practice experience.

She had always wanted to see if this young hero who abandoned everything and had the courage to pursue love had a good death.

Many years ago, she had posted a reward at Yinshi Bookstore, hoping to find Qingying through the ghost's eyes and ears, but there was no news.

Song Yushan almost thought that Qingying died quietly somewhere, but unexpectedly, news suddenly came at this time.

"Qinglong River..." Song Yushan took out the map and confirmed it.

Sure enough, she remembered correctly. Qinglong Creek was in the southwest of Linjiang County, not too far from Qingshui County, which they passed by when they came to Qingzhou City.

Half of Qinglong River is in Linjiang County, and the other half is in Sanhe County, and finally it merges into the Dajiang River.

She originally planned to go to the Heritage Academy, but immediately changed direction and walked outside Qingzhou Academy.

Regardless of whether the snake demon was Qingying or not, she had to go back and see.

Fortunately, Xiaoyi often travels between the two places to deliver letters. He already knows the route from Qingzhou City to Linjiang County in Yinshi. With him leading the way, it won't take long on the road in Yinshi.

Before leaving, she only sent a message to her senior sister about the matter.After leaving the academy, Song Yushan took out the black paper carriage and Xiao Yi led the way to the nearest entrance to the underworld.

This time she was alone, and the carriage was even more spacious, so she could lie down.

But it was also very boring. As soon as she left the inheritance academy, except for the ones she had already learned, all other inheritances from the inheritance academy automatically disappeared from her mind.

So on the carriage, she couldn't continue practicing.

Moreover, the environment in the underworld is not suitable for cultivation.

Fortunately, Song Yushan has exchanged the inheritance of fourth-grade alchemy master, talisman master, weapon master, and formation master from the jade seal space, so he can pass the time while he is in a hurry.

At first, it took nearly four years to get from Qingshui County to Qingzhou City, but when she went back, she rested in Yangshi during the day and traveled at night. It only took her seven nights to reach Qinglong River near Qingshui County.

Although Qinglong River is called "Xi", it is actually a big river. Several villages live near the river, and their domestic water comes from Qinglong River.

When Song Yushan arrived, it was still dark, and he heard crying from a distance.

There was an old woman, a young woman and a little girl of [-] or [-] or [-] years old by the river. They were all dressed in plain clothes. They were crying and lighting up river lanterns, as if they were paying homage to someone.

And in the river in front of them, there was a male ghost who was about the same age as the young woman and half of his body was covered in blood. He was looking at them with a miserable face, and tears of blood flowed from his eyes.

Song Yu was good at using yin and yang invisibility to hide her physical body, so the three of them didn't notice her approach.

Only the male ghost in the river noticed that a stranger was approaching, and rushed over with great resentment.

"Liu Yong! How presumptuous! This is Shopkeeper Song!"

Before Song Yushan could make a move, the manager of Yinshi Bookstore in Qingshui County who was guiding her next to her sternly scolded the ghost.

The steward was an old ghost for many years, and the powerful ghost's power overcame him, instantly dispelling the male ghost's resentment and regaining consciousness.

"Shopkeeper Song? Shopkeeper Song!" After Liu Yong realized who the visitor was, he knelt down straight towards her: "Please take action by Shopkeeper Song to get rid of the evil man-eating monster in this stream!"

The manager promptly explained: "Shopkeeper, his name is Liu Yong. He is a doctor from a small river village by Qinglong River. He originally had a loving wife and young daughter, and his life was very happy. But not long ago, when he went up the mountain to collect medicine, he was dragged away by a green snake and brought to the mountain. His neck was bitten off in the water, and his family has yet to find his body. It was he who told me about the white spot on the green snake demon's forehead."

While talking, more water ghosts floated out of the river.

Some of them have lost their minds and are confused, some have mutilated souls and bodies, missing arms and legs, and some even have only fragments of their souls and are on the verge of disintegration.

"These are also the ghosts who died in the belly of snakes in Qinglong River in the past year." said the steward.

Song Yushan looked at these miserable dead water ghosts and felt a little angry in his heart.

These ghosts, without exception, are all young and middle-aged male ghosts.

In one year, so many families along the Qinglong River have lost their breadwinners. This debt is too great.

If Song Yushan did not doubt ghosts, the wounds and bites on their souls were obviously not caused by ordinary beasts, and the souls were miserable, but the souls were also injured. Only demons could cause horrific wounds and seriously injure the souls at the same time.

Even Song Yushan, who always treats monsters equally, felt that this green snake monster could be called a "monster". It was really too cruel.

After many monsters become wise, they will avoid feeding on intelligent things even if they have not been enlightened by the moral concepts of the human race. However, this snake monster is specifically looking for people to attack. If the snake monster is not eliminated, the people by the Qinglong River will never have peace.

Regardless of whether the snake demon was Qingying or not, Song Yushan had to kill it to comfort the souls in the river.
