Lin Yu didn't know much about the so-called broken golden finger, but he knew that it was difficult to do, if there was no support of internal strength, it would not be possible to do it by strength alone, only by gathering all the internal strength on two fingers, and cutting it down quickly and accurately, he could rely on a moment of powerful explosive force to cut off the thick steel bar.

And through his understanding of Xiang Nantian, with Xiang Nantian's current physical condition, he can't do it at all!

"Yes, Master, how did you do that?!"

When Bu Cheng heard Lin Yu's words, he immediately asked suspiciously, "You've only stood up for a few days!"

"Haha, you two boys, you can't think of it, right?!"

Xiang Nantian smiled heartily, as if he enjoyed this feeling that Lin Yu and Bu Cheng couldn't guess, and said with a smile, "Have you forgotten, I just stood up for a few days, but my hands and arms have long been able to move, and since they can move, I have been insisting on exercising, so the strength in my hands and fingers have recovered well!"

Lin Yu and Bu Cheng suddenly realized when they heard this, yes, Xiang Nantian's arm could already move.

However, in the case of muscle atrophy, he can insist on exercising, which really requires huge willpower, which makes Lin Yu and Bu Cheng sigh.

"Jiarong, when I left just now, I specially explained to Xiao Hu, and asked him to try his best to read the book through your entry into the No. 1 secret warehouse!"

Xiang Nantian said with a solemn expression, "I really didn't expect that you would be able to understand these things, it is really not easy, you have to cherish it, and try your best to quickly improve your ability to a new level! The future of the Military Intelligence Department and Huaxia depends on you young people!"

Lin Yu was overjoyed when he heard this, and hurriedly nodded again and again: "Don't worry, Xiang Lao, I will definitely work hard!"

That's great!

It's just great!

As long as Lin Yu thought of the shocking contents of those strange books and classics in the No. 1 warehouse, he couldn't suppress the ecstasy in his heart, it was simply a huge treasure, if he could study all the books in the No. 1 warehouse thoroughly, then his strength might be at least doubled on the basis of the current one, and then it would be the existence of no one before or since!

But it takes time to read these books, a lot of time, so that's why he wants to enter and exit the No. 1 secret warehouse without restrictions.

Bu Cheng on the side was also excited, because when Lin Yu learned some Qimen secret techniques, he could also follow along to learn some, so as to improve his cultivation.

After Bu Cheng sent Xiang Nantian back to his residence, he followed Lin Yu back to the medical hall.

Before leaving, Xiang Nantian also specially instructed Lin Yu, this Tokugawa is a sinister master who will repay him, and let Lin Yu be careful.

Lin Yu agreed, but he didn't pay much attention to it, and after returning to the medical hall, he couldn't wait to study the ancient book that recorded the "Supreme Pure Body", and he also wanted to cultivate into the Supreme Pure Body, but once he practiced the Supreme Pure Body, the body of Brother Rong would be invulnerable!

At that time, he will naturally not be afraid of any kendo master alliance.

However, it was still the same as the bottleneck he had encountered before, and some of the Heavenly Treasures that had been cultivated to the Pure Body could not be found at all, so he tried to use the dried medicinal herbs made from the Tai Sui that he had stored before with several precious medicinal materials to replace the Genius Earth Treasure.

After all, among the medicinal materials he had in hand, the most valuable and the most effective were this Tai Sui, as well as the hundred-year-old Ganoderma lucidum and thousand-year-old ginseng before.

Although it is not as good as heaven and earth, it can also play some similar roles, but unfortunately, the amount of ginseng is not much left.

That night, he tried to arrange these medicinal herbs, and after they were decocted, he drank them himself, and then sat cross-legged according to the cultivation method recorded in the book, put his hands on his abdomen and clasped them tightly, and then tried to use the spiritual power in his body.

Ordinary occult masters have internal strength in their bodies, but what Lin Yu has in his body is the spiritual power inherited from his ancestors, compared to the internal strength of ordinary occult masters, it is stronger by I don't know how many grades, so it is naturally twice the result with half the effort.

Moreover, after the nourishment of those poisonous flower liquids, the spiritual power in Lin Yu's body had already grown to a very considerable extent.

But it's a pity that this powerful spiritual power, in addition to being able to control it during acupuncture, he doesn't know how to control it at all on weekdays.

But after he meditated cross-legged according to the cultivation method of the Supreme Pure Body, the spiritual power in his body began to flow slowly down his body, and a warm feeling of warmth came, making his body feel very comfortable.

Lin Yu even felt that he could control these spiritual powers to some extent, trying to gather them into his arms or legs, although it was still a little difficult, but it was already a great improvement for him.

After he finished cultivating, he slowly exhaled and breathed, opened his eyes, and found that his whole body was soaked with sweat, and his body was slimy, and at the same time, there was a layer of blue-black mud-like objects on the surface of his skin, which might be some dirt excreted from his body.

Lin Yu got up and went to the bathroom next to the inner room to take a shower, feeling extremely comfortable and refreshed.

After going to bed, he unconsciously thought of Jiang Yan again, although Jiang Yan would come to see him from time to time at noon these days, but he hadn't had a skin-to-skin kiss with Jiang Yan for a long time, and his heart couldn't help but be a little itchy, and he couldn't sleep over and over.

He simply got up and looked at the book again, and couldn't help but think of a very strange question in his heart, if he really practiced the pure body, would Sister Yan be able to stand it......

Lin Yu watched "Three Xuan Jingyi" for a night, and found that there were many records of cultivation methods such as immortality, in his opinion, most of them were just legends, and they were not realistic at all.

However, there was a page of information that suddenly caught his attention, and he immediately read this passage carefully.

The content mentioned here is related to traditional Chinese medicine, which probably means that through the combination of some medicinal materials, although immortality cannot be achieved, it can effectively improve the physical fitness of the human body, prolong the life span of human beings, and enable human beings to easily live to the normal age of 150 or 60 years old.

Lin Yu was shocked in his heart, and found that although these contents were theories thousands of years ago or even more ago, they were very consistent with current medicine and science!

At present, there are three middle schools in society that believe that the normal age of human beings can reach more than 100 years old.

Among them, the growth period theory states that the life span of mammals is about 5-7 times that of the growth period, while the growth period of humans is about 20-25 years, so this theory believes that the natural life span of humans is 100-175 years.

The second is the cell theory, which believes that the natural lifespan of the human body is positively correlated with the division cycle of cultured cells in vitro, and the natural lifespan of human beings is about 129 years old according to the method of cell division.

The third is the maturation theory, which is inferred by the time of sexual maturity and holds that people can live to be 112-150 years old.

Now the life expectancy of human beings has been greatly improved compared with our ancestors, and more and more people have lived to be eighty or ninety years old, so it is a very practical and reliable thing to promote the growth of human life expectancy.

Lin Yu carefully examined the medicinal materials mentioned in the book, and couldn't help but secretly marvel, impressed by the ancients, and found that the combination of these medicinal materials can promote the metabolism of human cells, so that the harmful cells in the human body can be metabolized as soon as possible, and maintain the health of the human body, which can naturally increase the life span of people!

Maybe the ancients didn't know what this principle was, but it is completely consistent with what medicine and biology have been studying now!

Lin Yu was excited, if these prescription experiments were really successful, did it mean that they could take the lead in making a major breakthrough in effectively improving human physique and prolonging human life before other Western countries!

At that time, the bioengineering project established by the Li Group may also become a hit!

Thinking of this, he couldn't wait to take out his mobile phone to call Li Qianjue, but before he could make a call, the mobile phone rang first.

Seeing this mobile phone number, Lin Yu couldn't help but be stunned, and then shook his head and smiled bitterly, thinking that it was really time for her to make this call.
