2010.

After the old man Mu Qingfeng celebrated his 100th birthday, he left a will to pass on the Nanshan Academy on the Wangri Cliff to Mu Zhengyang, and he died before winter came.

Everyone else thought that Mu Qingfeng only left a will for Mu Zhengyang, but in fact, the old man privately gave Mu Zhengyang a copper key with a strange shape.

Nanshan Academy is perched on the top of the Wangri cliff, and only birds occasionally visit on weekdays.

When Mu Zhengyang was a child, he often went to Nanshan Academy with Mu Qingfeng to play, but Mu Zhengyang has never been there since Mu Qingfeng left.

Half a month ago.

Mu Zhengyang was a little upset waiting for the results of the civil service examination at home, and accidentally turned to the copper key given to him by Mu Qingfeng back then, and missed his great-grandfather Mu Qingfeng, who had loved him since he was a child, so he climbed to the Nanshan Academy on the top of the Wangri Cliff alone to relax.

Although Nanshan Academy has a history of 67 years, it was often renovated during Mu Qingfeng's time, and on the whole it is very well preserved.

Obviously, no one has come to Nanshan Academy to study for decades, and everyone doesn't understand why Mu Qingfeng is obsessed with doing this!

When Mu Zhengyang climbed the Wangri Cliff, the courtyard of Nanshan Academy was overgrown with weeds, the furniture was covered with thick dust, and huge cobwebs hung on the eaves in the corners of the walls.

In fact, the so-called furniture is only a few tables, a few chairs, two wooden barrels, and an old-fashioned hardwood bed, Mu Zhengyang saw things and thought about people, fetched water from the ancient well in the backyard, cleaned the Nanshan Academy, and accidentally found a rusty iron box in the cellar of the warehouse, and a simple copper lock hung on the box.

"Could it be that my great-grandfather gave me a copper key to open this box?"

Mu Zhengyang thought suspiciously, inserted the copper key into the leading keyhole, and actually opened the iron box.

The inside of the iron box was plated, smooth and bright after weather, and at the bottom lay a book and a jade bottle poured on top of the book.

The dark blue cover of the book reads 'Cultivating and Reading Heirlooms', and a withered willow branch is stuck in the mouth of the jade bottle.

Mu Zhengyang picked up the dark blue book in his left hand, held the turquoise jade net bottle in his right hand, and the next second the book and the jade net bottle disappeared directly.

When Mu Zhengyang felt strange, the book and the jade bottle reappeared in Mu Zhengyang's hand, and after several trial and error, Mu Zhengyang confirmed that he was not hallucinating......

"It's too miraculous! The book that can deduce the supreme avenue, and the jade bottle that condenses the essence of heaven and earth, are more powerful than the magic weapons in myths and legends! Such two things against the sky actually appeared in the iron box left by my great-grandfather! Who is his great-grandfather?"

Books and information about the jade bottle slowly appeared in Mu Zhengyang's mind, which also made Mu Zhengyang more and more curious about his great-grandfather's past.

When his great-grandfather was alive, he insisted on repairing Nanshan Academy, and before he died, he passed Nanshan Academy to himself, and gave him a key that could open the iron box, so that he could get the miraculous books and jade bottles, obviously in order to let himself inherit Nanshan Academy, so Mu Zhengyang refused to report after being admitted to the provincial government office, and specially registered a public welfare academy, but he couldn't explain these to his family.

......

Seeing Mu Zhengyang looking into the distance, Mu Erya shook his palm in front of Mu Zhengyang's eyes, and urged: "Yangyang, why are you stunned? I have agreed to your conditions, hurry up and teach me the secret of weight loss!"

Some things will eventually come to light, Mu Zhengyang didn't dwell on it for a while, and smiled at Mu Erya, who was eager to lose weight, and smiled lightly: "It's nothing, my weight loss secret is simple and simple, and it's complicated to say it......!"

Mu Erya thought and found that something was not quite right, and said to Mu Zhengyang with a strange face: "Brother, you didn't play tricks on me, did you?

"Haha, old lady, you are still very talented! My secret set is called the "Three Character Cultivation Sutra", which I comprehended from the "Three Character Sutra"!"

Mu Zhengyang got the book except for the cover, the rest of the pages are blank, he read the "Three Character Sutra" casually after reading it a few times, the words "Three Character Cultivation Sutra" appeared on the blank page, and then read it hundreds of times a day to complete the deduction of the "Three Character Cultivation Sutra", including the explanation of the essentials of the action, and the precautions for breathing.

Only half of the "Three-Character Body Sutra" made Mu Zhengyang lose twenty pounds in more than ten days, and he became a muscle, and Mu Zhengyang felt that his strength had been greatly improved!

Mu Erya raised her hand again and knocked on Mu Zhengyang's forehead, and said dissatisfiedly: "What about entertaining your sister?

"I didn't have time!"

Mu Zhengyang tried "The Three Character Classic", "Hundred Family Names", "Thousand Character Text", "University", "The Mean", "Mencius", etc., and reacted to the basic classical books such as "Three Character Classic", "Hundred Family Names", and "Thousand Character Text", which may be related to his too shallow realm.

Mu Erya pretended to be negative and left, "It seems that you are thick-skinned now, do you think you are very resistant to beating? I will call my father up to try it? Let's just say that you are a famous college student who runs a college and reads the "Three Character Classic" that only kindergarten children read every day!"

Mu Zhengyang was really afraid that Mu Erya would provoke his father Mu Qingshan, but no one believed him when he told the truth to his sister, so he had to change his way, and grabbed Mu Erya and said: "Don't! Dad has eaten my heart raw now! I'm going to teach you a few sets of movements seriously, and I have to pay attention to my breathing rhythm!"

Mu Erya nodded with satisfaction and said, "It's not much wrong!"

Mu Zhengyang demonstrated in front, Mu Erya followed behind, Mu Zhengyang corrected several mistakes in Mu Erya, as for the breathing rhythm, this thing is not in a hurry, just teach Mu Erya the basic movements first!

Mu Erya followed Mu Zhengyang for three hours, and at first she thought that the movements taught by Mu Zhengyang were quite intense, but later she suspected that these movements had no fitness effect at all.

Because normally, with the increase of exercise, the speed of human sweating also increases, but Mu Erya found that the speed of sweating gradually decreased......

"Yangyang, you really lost weight in this way? Why is it so different from those fitness coaches on the Internet? I was a little tired at first, but then I didn't feel much anymore, does this fitness really work?"

If Mu Erya hadn't seen Mu Zhengyang refine a perfect body of muscles, and he was also his own brother, he would definitely suspect that Mu Zhengyang was hiding his secrets and didn't teach her the real know-how.
