As early as two years ago, Li Xian had successfully built the foundation, and now it is the second phase of the foundation, ready to impact the realm of the third phase, and the immortal medical skills learned by Ren Quan Lao Dao are also quite rewarding, not to mention the flesh and bones of the dead, and the injuries of ordinary immortals, it is absolutely not a problem.

But the more I studied, the more I knew how difficult the old wound on Lao Dao's body was.

After three years of getting along, Li Xian and Ren Quan have become familiar with the relationship a lot, knowing that although the old man has a strange temper, is extremely hot, withdrawn, and explodes angry and scolds people at every turn, but in terms of behavior, at least he can really do what he says, and there are only a handful of people who can do it on Shijie alone.

After getting along for a long time, there are some feelings, if he really helps Ren Quan Lao Dao heal his injuries, Li Xian is really willing to make some efforts.

It's just that in the past three years, Lao Dao's injuries have been getting worse day by day, until half a year ago, almost to the point where he couldn't suppress it, and he rolled frantically on the ground in pain.

The situation at that time seemed to be a hundred times more serious than the pain that Li Xianshiyan endured.

But Lao Dao is also stubborn, so he just held back and didn't snort.

In this way, the old wounds began to flare up more and more frequently, starting once a month, to once every three to five days, and then to almost every day recently......

Tortured a senior master who seemed to be strong in mana and immortal wind bones into an old cripple with gray hair and skinny bones, as if he would be extinguished like a candle in the wind at any time.

During this period of study, Li Xian also found some abnormalities, that is, Ren Quan Lao Dao obviously mastered two kinds of immortal medical skills, one is the orthodox medical skills recorded in the classics, which he learned and mastered during this time, and the other is a little weird, whether it is the basic idea or the treatment method, it seems that it is not a system at all with the previous orthodox immortal medical technique, but the effect is inexplicably many times stronger, Ren Quan Lao Dao can support until now, many times it is completely dependent on the second medical technique to treat himself, but in terms of this second strange medical technique, Ren Quan Lao Dao's mastery is obviously not in place, it should only have mastered some skin, even this bit of understanding seems to have very serious mistakes and problems, resulting in the effect of treatment is sometimes good and bad, and sometimes even no effect at all, and even has the opposite effect, causing Ren Quan Lao Dao to only watch his injuries get worse and worse.

"It can't be delayed any longer, boy, during this time, you should also have a mastery of the basic medical skills of the Immortal Family, since this is the case, let you take a look at this thing and see if there is anything to gain." On this day, after another extremely serious attack of old injury, Ren Quan Lao Dao lay on the ground, gasping weakly for a long time, and blood kept flowing from the corners of his mouth, obviously the internal organs were also seriously injured.

Then, he took Li Xian into a secret door, entered an underground room, took out a shabby-looking booklet, held it in the palm of his hand with great care, and after a long time, he gritted his teeth and handed it to Li Xian.

"Look at it and tell me what you see......"

This is a very shabby booklet, I don't know what material it is made of, and it seems that there is only the top half, the second half seems to have been torn apart, and the text on the cover is a very old immortal script, and the oldest immortal rune graphics that Li Xian used to visualize before look somewhat similar, and the content written on it is the entire text of the Black Immortal Supreme (the content here is missing and cannot be seen clearly......

"Black Immortal?" Li Xian muttered, and Lao Dao said impatiently, "It's not for you to look at the cover, but for you to look at the content inside, to see if you can comprehend anything." ”

Li Xian came back to his senses, looked at the pages of the book, and found that the content inside was written in the same words, and at a rough glance, he basically recognized it, but after those words strangely entered his mind, he seemed to come to life, constantly changing, jumping and twisting, and Li Xian seemed to know what each word meant, but the meaning of the combination, it was difficult for him to understand.

After watching it for a long time, I even have a feeling of dizziness and nausea.

"What, is it really the same as I was at the beginning? Indeed, with your current cultivation, it seems that it is still too reluctant to observe this ancient immortal text, but I didn't expect anyone to be able to observe anything in a short period of time, after all, the old man has studied it for so many years...... So, if you are free and interested during this time, please come and take a look...... By writing down the scriptures we remember, we may be able to corroborate each other and learn from them...... Be careful not to look at it for too long at a time, otherwise even with the immortal body we are waiting for, there will be problems. The expression on Ren Quan's face was a little disappointed.

Li Xian nodded, continuing to focus on the shabby pamphlet in his hand.

Closing the booklet in his hand with a snap, Li Xian fell into deep thought, according to Ren Quan's old way, every time he watched for half an hour, he had to rest at least for a while before he could continue watching.

After doing this several times, Li Xian finally made it clear that the second kind of Ren Quan Lao Dao is a little weird, but the effect is surprisingly strong, it should be learned from this ancient booklet, but the ancient immortal text on this booklet seems to have some kind of strange liliang, and it seems to have a strange feeling of coming to life after looking at it, and he clearly knows what it means, but when combined, it seems to be difficult to understand, easy to forget, and even seems to be constantly changing every moment, not only that, but it also makes people dizzy and have an inexplicable headache。

And Li Xian has a hunch that even if he forcibly memorizes all the changes and analyzes and understands them according to his own ideas, Zuihou may be like Ren Quan's old way, extremely incomplete, at most he has mastered some fur, and there are many mistakes and omissions, the effect is extremely unstable, and he can't grasp the real essence of it at all.

Li Xian decided to take a different approach to this problem.

"Digitize this black immortal book, the goal, to find out the real comprehension method. ”

Under the effect of the ability, countless data suddenly appeared in front of him, and the words on this black immortal book were also recorded, analyzed, and analyzed.

The mission is established, and the estimated time to get results is eight days.

It seems that in the past eight days, he can only try the method of Ren Quan's old way, Li Xian frowned, and continued to carefully observe the ever-changing immortal texts in this booklet, and from time to time recorded the little content he understood.

Eight days later, the ability found four or five possible useful methods for him, but Li Xian tried the first ones, and all of them failed.

"This is a kind of zuihou, if you can't even do this, I guess there is really no way. Li Xian slashed his finger and smeared the blood on his finger onto the Ancient Immortal inscription in the mutilated booklet.

After the foundation was successfully built, now his body was already an immortal body, and even the blood naturally emitted a strange fragrance.

"Hey, it seems to work. "The blood smeared on the words, and instead of forming a stain, it was as if it were alive, sucked in by the words, and the pamphlet was still clean, and there was nothing.
