Afternoon break.

    Other seniors are taking their midday nap.

    Chen Yun was summoned by Wang Zixi to his bedroom.

    "Sit."

    Wang Zixi pointed to the stool.

    "Thank you, brother."

    Chen Yun sat down.

    Wang Zixi did not sit down, his single hand was placed on his back, slowly said: "Master asked me to pass you a hundred days of building foundation method, do you know what a hundred days of building foundation?"

    Chen Yun shook his head, "I don't know, please teach me, brother."

    Wang Zixi nodded and said: "The so-called building foundation, as the name suggests, is to dig a foundation. High buildings are built on flat land, and the key lies in digging a solid foundation. Only after the foundation is well-built can a high building be constructed. If the foundation is not solid, even if a high building is completed, it will collapse at any time."

    The term "digging a foundation" roughly means laying the groundwork.

    Chen Yun understood and listened attentively.

    Wang Zixi continued: "Everyone who practices Taoism needs to go through the process of building foundation before they can start their future cultivation path. After a hundred days of building foundation, since the sacred fetus is being nourished, it is essential to practice sexual cultivation. When the flow of energy is obstructed by strong resistance and the internal energy is not enough to break through the disease, the flow of energy will automatically change its route. When another route is obstructed again by strong resistance, it will change its route again and again. In this way, it not only loosens all the small diseases that can be broken through with sufficient internal energy but also exposes one by one the diseases that cannot be broken through temporarily due to insufficient energy, which is called the process of finding diseases and is also known as a hundred days of building foundation."

    Chen Yun knew these contents were very important, so he didn't speak but listened carefully.

    Wang Zixi said: "To know how long it takes to unlock the meridians, you need to understand the human structure. These you can learn from Li Si later, and I will first teach you the mantra for the cultivation method."

    Chen Yun hurriedly stood up and said: "Thank you, brother."

    Wang Zixi remained cold and simply grunted, then began to impart the incantation of the cultivation method, "The three energies become one, one is essence, one is spirit, and one is Qi. These three combine into a unity, the root of the Qi of heaven, earth, and man..."

    Chen Yun recited silently.

    Wang Zixi spoke with fluctuating tones: "There is a natural breathing secret in Taishan called 'Longevity and Long Sight...' "

    He imparted the cultivation method for a tea ceremony's worth of time.

    At the end, Wang Zixi imparted the final part of the cultivation method, "... The method of guarding one, one must know the will of heaven, create and nourish all things without words, and when the work is completed, it is not killed... The divine does not guard one and cannot be created, humans do not guard one and cannot be sustained. One is the root, all things proceed. If one knows one, all things are complete."

    After speaking, Wang Zixi asked: "Remember it, Chen's younger brother?"

    Chen Yun was momentarily at a loss for words.

    This cultivation method is several thousand words long.

    How can you remember it after hearing it only once?

    He spoke truthfully, "I haven't."

    Chen Yun originally thought that his answer would anger Wang Zixi into a scolding.

    To his surprise, Wang Zixi's face was full of admiration for the first time, "Sincerity is the way of heaven, thinking sincerely is the way of humans. Not knowing is just not knowing, which is true. I have heard Master say that you can read characters. Well, here is a book that records the method of a hundred days of building foundation. Take it and ponder it quietly."

    After saying this, Wang Zixi, like Wang Laozhi, magically produced a book out of thin air.

    Chen Yun, witnessing the great law of immortals, couldn't help but feel a bit envious.

    However, he knew that Wang Zixi's character was different from that of Wang Laozhi, and it was best not to ask things that shouldn't be asked.

    He reverently took the book with both hands and said, "Thank you, brother."

    Wang Zixi waved his hand and said, "Go out."

    Chen Yun withdrew.

    ...

    Finally, I have obtained the method of a hundred days of building foundation!

    Chen Yun's heart was burning as he made his way to the herb garden.

    However, when he came to the herb garden, he was greeted with a bucket of cold water by Li Si.

    In the pharmacy, Li Si yawned and said, "It's impossible to build the foundation without studying the human body structure for at least a year and a half."

    Chen Yun was puzzled and said, "Is it really necessary to wait a year and a half before I can start the hundred days of building foundation?"

    "Then what?" Li Si looked at him with a matter-of-fact expression and said, "If you don't understand what meridians and acupuncture points are, how can you build the foundation?"

    Chen Yun thought about it and agreed.

    However, since he had finally encountered immortals, he still wanted to show off and be recognized one day by Zhongli Quan and then be able to practice the true great arts.

    It's too long for a year and a half.

    Fortunately, at this moment, Li Si said, "The year and a half I mentioned is about the flow of Qi. For now, you can try plugging and repairing leaks. Um, as a virgin, it should be easy for you to do so."

    Chen Yun rushed to say, "Please, brother, show me the way."

    Li Si smiled and said, "All right, I'll play the role of a teacher this time."

    He was a decent person, and besides telling Chen Yun how to plug and repair leaks, he spent the whole day teaching him about the structure of the human body.

    ...

    At night, he returned to his room.

    Chen Yun picked up the book given to him by Wang Zixi and read it by the light of a candle.

    Although the classical Chinese was complex and difficult to understand, he could roughly grasp the meaning of this hundred-day foundation method through some effort.

    Actually, the principle of the hundred-day foundation method is quite simple.

    The rough idea is to first unlock the meridians.

    Because only when the meridians are unlocked, true qi is generated, its one will become "Golden Pool" when it rises up along the Dufu vein to the top of the head and then descends to the gum junction of the oral cavity; its other will become "Jade Fluid" when it rises up along the Renmai vein to the lower jaw of the oral cavity, and then can be refined into qi with "Golden Pool" and "Jade Fluid".

    Chen Yun still doesn't know how the process of refining essence into Qi specifically works.

    However, he was able to see the several levels of the hundred-day foundation method from this cultivation method.

    The first level is plugging and repairing leaks.

    After entering the stage of adolescence, both males and females will experience normal physiological phenomena.

    Males will experience semen loss.

    Females will have menstruation.

    In Taoist health preservation studies, this is called "body leak," also known as "leaking body."

    Jing and blood are the "precious treasures" of human life and the fundamental basis for human reproduction and survival.

    However, the process of reproduction doesn't require men to walk every day and women not to lose blood every month.

    However, humans are naturally greedy for pleasure and more attached to the joys of the bed, which leads to the waste of life energy, loss of vital essence, and a plethora of diseases, preventing them from enjoying a long and healthy life.

    Therefore, the first step of the hundred-day foundation method for cultivating immortals and magic has always been "plugging leaks and repairing weaknesses."

    Chen Yun silently read the book, "The second step is the flow of qi."

    The flow of qi is divided into four parts.

    They are respectively obtaining Qi, circulating Qi, dilating and striking.

    The first step is to feel the flow of qi.

    If you can't find the flow of Qi, how can you talk about unblocking the meridians and reaching the disease sites?

    The second step is to utilize the Qi sense to traverse the meridians.

    Because the essence has not been refined into qi yet, the "true qi" generated at this time cannot be retained in the body.

    On the contrary, it will consume essence and Qi.

    Therefore, it is particularly important to supplement nutrition during this period.

    Once you can skillfully circulate Qi, then you can begin to dilate.

    Since the normal tissues and meridians of the human body are unobstructed, when Qi flows through them, there is usually no sensation.

    However, there are usually many small stagnant points in the human meridians.

    These small stagnant points have not yet formed diseases, so there is usually no feeling during normal times. However, due to the increase of energy after practicing the method, the strength of flow also increases accordingly. Moreover, during the practice, consciousness is focused on the body. Therefore, the sensitivity of body perception is much higher than that during normal times.

    When the flow of Qi is used to unblock these small stagnant points, it will produce eight sensations: heat, swelling, numbness, pain, itching, coldness, pressure, and the sensation of ants crawling.

    It is commonly known as "Qigong sense".

    When the flow of Qi reaches the meridians with obvious diseases or abnormalities, the movement of Qi is blocked by strong resistance.

    This is because in all areas of qualitative lesions, the meridians are in a state of stasis or blockage.

    The flow of Qi forms two opposite forces when it encounters resistance from the lesions in the meridians.

    Impact force and resistance force.

    The lesion site will show obvious reactions when it is subjected to external force.

    Such as: pain, fever, bleeding, and other similar reactions like a worsening of the condition.

    This is what is commonly referred to in internal alchemy as "Qi striking the disease site."

    Internal alchemy calls this stage the "process of great death and great vitality" before the "rebirth and transformation."

    In fact, it has almost reached the end of the hundred-day foundation method.

    Chen Yun has a general understanding of the principles of foundation building.

    At the same time, he also sees the specific time for the hundred days of foundation building in the book.

    The "hundred-day foundation building" is not literally for one hundred days of foundation building, but rather the number of seats that need to be built before completion.

    Generally speaking, around the age of sixteen, one needs to complete three thousand and five hundred sessions.

    This means that at least three thousand and five hundred sessions are required for the hundred-day foundation building.

    This is a base number.

    The prerequisite is that from each session, a clear and sweet saliva can be produced.

    If it is not clear or not sweet, it cannot be counted among the three thousand five hundred sessions.

    This base number is for a sixteen-year-old virgin body with good health and firm determination in each session.

    "It's too long for a year and a half."

    After thinking for a long time, Chen Yun secretly thought in his heart, "Since the book has recorded the foundation-building method, I might as well try it out. If it doesn't work, I can study it slowly later."

    Thinking about it, he began his first practice.
