There is not much difference between Chinese and mathematics and history and modern school textbooks, but there are some differences between biochemistry and physics and modern times.

Xu Fei put down the books, and in his heart, the times were developing, and most of the knowledge in the textbooks of biochemistry and physics was outdated. However, Xu Fei is not to learn knowledge, but to see what is the difference between what humans learned more than a hundred years ago and what knowledge is now.

There were not many books on the seventh shelf, but these books surprised Xu Fei a little, because these books were martial arts classics. After carefully reading a few books, Xu Fei found that these martial arts classics are all martial arts classics of the ancient martial arts school, including "Liangyi Boxing", "Soft Boxing", "Yiquan" and so on.

Xu Fei immediately felt like a treasure and began to read quickly. Now Xu Fei doesn't need to learn now, but first memorize and then say, remember and then deduce in consciousness, and then slowly study.

Of course, what Xu Fei hopes to understand most now is "Breaking Killing Fist", but Xu Fei knows very well that "Breaking Killing Fist" is a combination of ancient martial arts and modern martial arts, since there is no way to understand "Breaking Killing Fist" now, then learning the martial arts of the ancient martial arts school first can also make Xu Fei gain something, I can't say that the stones of other mountains can attack jade, what if there are similar fist intentions in these martial arts to "Breaking Killing Fist"?

While reading a book and preferring the right time to practice the Furnace Fist, the day passed quickly.

The sun was setting, the sunset was full, and the hunger in his stomach made Xu Fei wake up from the vast world of martial arts. Seeing that it was getting late, Xu Fei stood up a little reluctantly.

Putting all the books on the seventh shelf, Xu Fei did not go to the eighth shelf, but returned to the first shelf and pulled out a book.

Looking at this book, Xu Fei showed a smile on his face.

"Didn't you let me raise the consciousness of those eight fierce beasts? This book is just the right thing to use. ”

Out of the library, Xu Fei walked down the mountain, and saw the beasts all over the mountain, Xu Fei also wanted to make a barbecue, but thinking about the fierce beasts all over the mountain, Xu Fei still gave up.

It's just that he can't stop eating when he is hungry, so Xu Fei went to the forest to find some wild fruits to eat.

A large pile of wild fruits floated beside Xu Fei, Xu Fei took a bite of them, and while eating wild fruits, Xu Fei couldn't help but think of his parents and sister, as well as Yu Zhen, Lin Ziyi, etc.

"I don't know if my parents and sister will think I'm dead. Did Yu Zhenjing and Lin Ziyi return to the seventh training camp safely? ”

Xu Fei was a little annoyed and wanted to contact his parents to reassure them, but now that he was under house arrest on Wudang Mountain, he had nothing to do.

I had just taken two steps when the sky in front of me suddenly darkened. When he looked up, he found that it was not that the sky had darkened, but that a golden fox about fifteen meters high and fifty meters long was blocking in front of him.

Xu Fei's spirit immediately tensed, staring at the golden fox, which just stopped in front of him, without making some superfluous movements, and there was not the slightest wave in his eyes.

"It turned out to be Yunxia? Looking for me? Xu Fei pretended to be calm.

"Yunxia" is Xu Fei's name for this fox, originally Xu Fei remembered the masculine name, but Xiong Hei said that this fox was female, so Xu Fei changed his mind and took the name "Yunxia".

As soon as he heard "Yunxia", the fox's eyes narrowed slightly, and an inexplicable pressure emanated from its body, it lowered its head to look at Xu Fei, the huge fox's face seemed to be brewing strong dissatisfaction, and a huge head approached Xu Fei, with the intention of swallowing him.

Xu Fei couldn't help but scold Xiong Hei in his heart, if Xiong Hei didn't have to let him choose a name on the first day, he Xu Fei would definitely not take this name at will. Speaking of this name, Xu Fei actually couldn't think of any good name, and he only thought of it when he looked up at the sky when he saw the clouds, and this fox was dressed in gold and looked like the sunset on the horizon, and it was a bit inappropriate to use the word cloud, so Xu Fei named it "Yunxia".

At this time, Xu Fei's mind changed rapidly, and he opened his mouth and said: "Actually, I want to be friends with you, otherwise I wouldn't have given you such an extremely meaningful name." ”

"Yunxia"'s huge head approaching Xu Fei stopped, and there was an interesting look in his eyes, as if he wanted to hear how Xu Fei explained.

Seeing that the fox stopped, Xu Fei said seriously: "'Or perched on a gang, or a long stream; Xia Friends Yunpeng, Creation and Travel. 'Your name is actually taken from this ancient text, and Xia You Yun Peng means to be friends with Yun Xia. ”

Xu Fei looked at the female fox's expression as he spoke, but its fox face was not as easy to see joy and anger on a human face.

So Xu Fei continued: "And the cloud is white, which represents purity, and the xia is golden, which represents beauty and elegance. So I came up with your name with all my heart's work. ”

Xu Fei didn't dare to say that the ancient text came from an epitaph, otherwise he would be buried in the belly of the fox immediately.

"That sentence 'Xia Friends Yunpeng' is proof that I want to be friends with you." Xu Fei said sincerely.

Seeing Xu Fei's sincere appearance, "Yunxia" put away the pressure emanating from his body, and looked at Xu Fei seriously for a moment, one of the three tails rolled up, and a wild boar three meters high appeared in front of Xu Fei.

With a loud bang, Xu Fei looked at the wild boar covered in black and long hair like a hill in a daze, and then looked at "Yunxia" and said in a daze: "Are you sending me food?" ”

"Yunxia" narrowed her eyes slightly, and did not respond to Xu Fei, but just stretched out her pink tongue and licked the corner of her mouth.

Seeing its greedy appearance, Xu Fei was inexplicably a little lost and embarrassed.

Coughing lightly, Xu Fei said: "It's not good here, you have to go to the square, and I can't carry such a big wild boar." ”

Xu Fei is telling the truth, this three-meter-tall wild boar is at least 1,500 catties, and Xu Fei's current strength can't carry it at all.

Without saying a word, Yunxia rolled up the wild boar with his tail again, strutted his head high, and walked down the mountain with graceful steps. Xu Fei walked behind it, looking at its back and elegant steps, a thought was born in his heart.

"I don't know if I'll ever get a chance to ride it in the future."

On the square, "Yunxia" put the wild boar on the ground, and then looked at Xu Fei, as if he was saying in his eyes: "Good friend, hurry up and concoct it and feed me." ”

Xu Fei saw that its eyes were staring at him, and he didn't dare to slack off, and went directly to the small courtyard, Xiong Hei was no longer in the courtyard, it was empty.

Xu Fei looked for a while before finding a large water tank, and there was also a deep well in the courtyard, after Xu Fei fetched water, he carried the water tank to the square, and picked up a lot of wood from the surrounding forest, set up a fire and burned the water.

Xu Fei looked at the Miao knife in his hand, pulled out the sheath, and looked at the wild boar and couldn't help but smile self-deprecatingly.

"I didn't expect that the first time I Xu Fei used a knife was to 'kill pigs'."

Of course, the pig was dead, and it looked as if its throat had been cut by a knife, and its blood had dried up.

Xu Fei began to shave the wild boar with a knife, but although the wild boar was not a fierce beast, it had also been baptized by energy particles, and the hair on its body was like a steel needle.

Helplessly, Xu Fei can only use all his strength and the luck skills in "Breaking Fist" to scrape clean, but a knife will still make a rather harsh sound, Xu Fei even suspects that if he uses a little strength, he is likely to scrape out sparks. The knife is made of alloy, which is extremely sharp, and will not dull by shaving a wild boar's hair.

After a while, Xu Fei panted and withdrew his hand, the pig's hair was shaved clean, but the arm was still a little sore.

So Xu Fei began to disembowelment the pig.

After cleaning the internal organs, Xu Fei put aside all the edible ones, washed the wild boar with hot water, and then with the help of "Yunxia", he put the pig on the flame and roasted it with all his might.

An hour later, the wild boar was roasted golden, and a fragrance hit, Xu Fei felt a little regretful, but unfortunately there were no spices and no salt here, otherwise this roast pig would probably be even more delicious.

After baking, Xu Fei looked at the drooling "Yunxia" next to him and nodded.

"Yunxia" immediately stood up, not afraid of the flames, and directly picked up the roast pig and ran away, without even saying a word of thanks.

"It seems that this 'Yunxia' is an authentic foodie."

Xu Fei was not angry, but breathed a sigh of relief. He took out the ribs he had just taken from the wild boar from the pot next to him, put them on the fire and roasted them, then poured out the water in the pot, put the fat in the boar's body, and roasted them over the fire.

"Looks like it's time for Kumako to get me some pots and pans." Xu Fei touched his chin.

After eating and drinking, Xu Fei took a shower, but he had no clothes to change, so he could only be shirtless. After taking a bath, Xu Fei looked at the severed hand, a little silent.

After a day and a night, although Xu Fei used his mental power to protect and isolate the air, his hand still stinked a little. Smelling this smell, Xu Fei remembered the fragrance he had smelled when he was pointing out Wang Fu in the training camp before, and he had burst into tears unconsciously.

Wang Fu's death was a very major blow to Xu Fei, which made Xu Fei deeply perceive what life and death are impermanent, what is powerless, and what is weak.

For Xu Fei, in the process of escaping, he didn't have time to think too much, but now that he has free time, his heart will inevitably think of the nightmarish scene last night, think of Wang Fu's smiling face before he died, his heart is full of self-blame, and even his heart will think "It would be nice if it was himself who died." ”

No matter how strong Xu Fei is, he is indifferent in his heart, but he is only a sixteen-year-old boy after all. Young feelings, always sentimental.

Taking a deep breath, Xu Fei wiped his tears, and used his mental power, which covered this hand, only to see that this hand quickly dried up, and finally turned into something like dead wood.

This is Xu Fei using his mental power to drain the water of this hand, so that he is not afraid of rotting, he didn't think about burying this arm, he thought that one day if he could return to the human world, so that he could return this to Wang Fu's parents.

Letting go of his mind, Xu Fei began to study the martial arts of the ancient martial arts school he saw in the "library" today, and then exercised his thoughts to restore his mental power.
