Shenyin Shanhaijing

After the Mid-Autumn Festival, everyone dispersed.

Cui Ying continued to study in school and devoted herself to practice. She spent another three years to advance to the late stage of Jindan.

After graduating from Langya University, she followed Lu Chenjun's footsteps and entered the "Spiritual Bone Research Institute" under the "Monster Research Institute" as a graduate student to conduct "comparative teaching research" on the evolution of monster skeleton runes.

The bones of monsters are divided into spiritual bones, jade bones and fairy bones. Monsters of different realms have different runes, and monsters of different races also have different runes. Studying the evolution of runes of various monsters can help improve The level of the alchemy talisman array can even fill the life talisman of Chaos Qinglian.

"Lu Jinya", the director of the Monster Research Institute, is the clone of Lu Jiya, the 18th generation grandson of the Lu family. His true self became the Immortal Emperor and stayed in the City of Ten Thousand Demons all year round to study the evolution of the demon immortals.

Lu Jiya was originally the director of the Siren Research Institute, and his experimental subjects were mainly sea crabs and senbei.

As Qingmei became the Demon Saint and established the Ten Thousand Demons City in southern Xinjiang. He also established the "White Deer Cave Demon Garden" and the "Great Sage Research Institute" in the Ten Thousand Demons City. Lu Jiya's research subjects expanded to the entire demon clan.

Cui Ying's mentor Gu Limei is a Nascent Soul Lord who is already 1200 years old.

Gu Limei's husband, Lu Hengyuan, is the 215th generation descendant of the Lu family, 18 generations older than Lu Chenjun.

Because of the passage of time, the Lu clan has divided into many branches, and each branch reproduces at a different rate, so the generation gap is getting bigger and bigger. The main branch of the Lu family has reproduced the slowest, with only 65 generations so far, while the side branches have reproduced the fastest, reaching 280 generations.

Although Gu Limei is of higher generation, she is not an immortal and is not qualified to obtain the "Immortal Couple Token".

Cui Ying got the "Immortal Couple Token" in advance because she came from the era of the Five Hus and Sixteen Kingdoms and formed a golden elixir within a period of time, so she gained Xue Ningdan's favor.

Xue Ningdan did not give her the token without any principles, but because Patriarch Yideng once said that any woman who comes from Middle Earth, leaves her hometown and overcomes many difficulties, and follows the Lu family to the fairy world, belongs to heaven. Proud son needs special care.

Cui Ying didn't want to cause trouble and kept the token away on weekdays. Except for her family and a very small number of managers in the City Lord's Mansion, no one knew her origins.

As a tutor, Gu Limei was a bit harsh on her students and assigned many tasks to Cui Ying, making her so busy that she even had very little time to practice.

Since Lu Chenjun returned to Langya City, he spent several years working as a teaching assistant at Langya University, and by the way got a doctorate while working, and then entered the Monster Research Institute as an assistant researcher, working four days a week, six hours a day, with a lot of Spend your time practicing.

Seeing his wife so busy, he couldn't bear it, so he would sometimes help.

Every morning, a batch of demonic beast spirit bones are delivered to the laboratory.

Cui Ying's job is to scan the patterns on the spiritual bones, input the data into the computer, compare it with the basic rune library in the cloud, select the distinctive spiritual bones, and give them to the alchemist to refine them into elixirs. Then she would feed the elixir to the monster and observe and record the experimental data to verify the efficacy of the special runes on the spirit bones.

This experiment sounds simple, but is very complicated to perform.

As a small graduate student, it was impossible for her to cover everything. She only needed to pick two or three distinctive runes to complete her graduation thesis. But the instructor asked her to study as many runes as possible. Since then, the workload has been too much.

In the evening of that day, the two opened the "Book of Yin and Yang Harmony" and studied "The Fourth Transformation of Yin and Yang".

Lu Chenjun slowly recited: "The moonlight cannot be swept away, and the guest's sorrow cannot be explained. The jade dew produces autumn clothes, and the flowing fireflies fly over the grass. The sun and the moon are finally destroyed, and the heaven and the earth are withered... When the sun and the moon are born, the clouds are forged with fire essence and mercury. ..." As the saying goes, "Tai Chi produces two yangs, and two yangs produce four phenomena."

What is Liangyi? Liangyi refers to Yin and Yang, just like numbers have positive and negative, magnets have cathodes and anodes, and atoms have positively charged protons and negatively charged electrons. Yin and Yang are one of the fundamental avenues in the universe. Both scientific and technological civilization and cultivation civilization are inseparable from this proposition.

After Lu Chenjun finished reading the scriptures, he took out his mobile phone and logged into the second level of the Lu Family Secret Network.

There are ten floors in the Lu Family Secret Network. With his authority, he can only log in to two floors.

Each level has exercises, runes, magic circles, weapon refining methods and elixir formulas. The outermost layer only contains simple and basic things, while the inner layer contains profound knowledge. The ninth layer is for the Immortal Emperor, and the tenth layer is for the exchanges between saints.

Cui Ying has the "Immortal Couple Token". Her permissions are the same as Lu Chenjun, and she can only see the second floor.

Lu Chenjun opened the basic rune library and said: "The exercises we practice focus on yin and yang, and the focus of research is the yin rune and the yang rune. So I suggest that your topic be as close to the 'yin rune' as possible. There are 1500 basic yin runes included here. Talisman, and the same number of basic Yang Talisman. Leave the Yang Talisman part to me, and you will be responsible for the Yin Talisman part."

Cui Ying thought for a while and said: "You mean, let me select the runes related to the Yin Rune from the spiritual bones to study?"

Lu Chenjun nodded: "That's what I mean. There are too many types of runes. Rather than looking for a hammer here and a stick here and there, it's better to focus on one type."

Having said this, he clicked on the "Basic Pills" webpage and said: "Look here, pills are also divided into yin and yang. The yin-type pills collected here can not only calm the mind and calm the mind, reduce fire and nourish the kidneys, but also strengthen the body." It can strengthen the Yuan and repair the soul. These Yin elixirs are made from Yin materials, and it is said that some of them come from the underworld."

Then, he clicked on "Basic Magic Array" and "Weapon Refining Technique" one by one, and said: "Similarly, the magic circle is divided into yin and yang, and the weapon refining is also divided into yin and yang. In my opinion, you and I should divide the work and cooperate and study separately. The way of yin and yang is in line with the profound meaning of the Yin and Yang Harmony Book."

Cui Ying said: "My current work only involves runes, not weapon refining or elixir refining. The spiritual bones I selected are all given to others to refine elixirs."

"I know that you have just entered the Demonic Beast Research Institute, and the tasks are relatively heavy, so you don't have the energy to refine elixirs. It will not be too late to study it again when you have time in the future."

"Do you know if there are immortals who practice Yin-type skills alone?"

"Yes, it is said that both Taiyin Star Lord and Ancestor Minghe practice Yin system skills. Ancestor Minghe even became a saint by practicing the laws of the netherworld. The mental methods practiced by these two big men are all in the Lu family secret network. It’s included. Our skills are too limited and we can only see the directory and introduction. We don’t have enough points, so we can’t check the specific content.”

"Are there any immortals who only practice Yang attribute skills?"

"Of course! For example, the Red Emperor and the immortals of the Xihe tribe all have fire cultivation skills left behind."

"So, are there any immortals who practice the Yin-Yang Harmony Book?"

"I don't know. I don't know the origin of this technique. I searched the Lu family secret network several times and couldn't find it. Maybe it's because I don't have enough authority."

Since then, the gap between the yin and yang of the two people's cultivation methods has become wider and wider, but they have continued to combine and practice together, like sparks hitting the earth, shortening the distance between them.
