After the practice, Lu An washed and slept, cried Lingjing routinely early the next morning, and went to the school library after breakfast.

Of course, the purpose is to borrow books, but the books borrowed this time are different from the last time.

Lu An brought all the books about fitness this time and returned them to the library.

What he needs now is a book on Chinese medicine, not exactly Chinese medicine, but more about the ancient study of the human body.

It's just that there are more books in this area, Chinese medicine.

It's like modern research on the human body, and Western medicine is more.

Lu An wanted to read the library for a while like last time before leaving, but later found that most of these books were difficult to understand and could not be read in a short time.

In addition to these books, Lu An also needed a reference book, a dictionary of ancient Chinese.

The dictionary had to be used all the time, and instead of borrowing it from the library, I bought a copy from an outside bookstore.

With a thick stack of books, Luan returned home and began to study.

Coupled with the meridian acupuncture point map he bought, Lu An soon had a further understanding of his body.

After understanding, Lu An found that the Hou Tu Hegemon was really domineering.

When he was just driving the blood qi and refining the internal force, Lu An felt that he was pierced, but in fact, the meridians were torn apart by the blood qi.

This also caused the blood and qi in the back to run wildly and wreak havoc in the body.

If there was no spirit crystal to repair it, Lu An might be killed by his huge blood qi at any time.

From these books, Lu An discovered that the blood and qi of the human body come from the whole body, not from any one part, but the special energy of the human body is born in the process of blood circulation.

Although it is related to blood, it does not only exist around blood vessels, but also spontaneously diffuses in the body.

If there is no corresponding method, it cannot be transferred.

Ordinary people's blood qi, according to the Houtu hegemony method, can quickly be refined into internal qi.

Compared to blood qi, internal qi is easier to control.

However, Lu An felt that internal qi was indeed easier to control than blood qi, but it seemed to be a little less than blood qi, and its power was also reduced a lot.

In the process of quenching the skin, Lu An obviously felt that the efficiency of blood qi quenching and nourishing the skin was obviously much higher than that of internal qi.

It is also possible that the amount of internal qi is too small, and his own delusion may not be, but since the blood qi can be directly quenched, Lu An simply uses the blood qi to cultivate.

After reading the ancient human body research for a long time, Lu An had some concepts of the Houtu Hegemony Method, checked the blood qi in the body, and found that it was indeed as said in the book, the blood qi would be born on its own.

However, the speed of birth was fast and slow, and Lu An found that his newly born blood qi was only one-tenth of what he had before.

It took only one-tenth of the recovery in one night, eight hours passed, and the day was only twenty-four hours, and at most three-tenths of the recovery was made, less than a third, and it was far from a complete recovery.

After all this blood qi was consumed, Lu An began to die again.

It was still the kitchen knife, Lu An put it on the back of his hand, and with the greatest force, he pressed it tightly and pulled it left and right, only a shallow white mark, and then slowly turned red.

The capillaries inside may have been broken a bit, but the skin is not broken at all.

It seems that he has been able to achieve preliminary invulnerability, of course, cold weapons and guns.

In the case of thermal weapons, of course, it cannot be compared.

At this point, Lu An felt that he had not finished half of his quenching, and it was only the second day of cultivation.

It seems that even if you don't enter the Dao, there is a lot to be done in cultivation.

It's just that I don't know what realm the other cultivators are in and what their combat power is.

After two days of quenching, Lu An wanted to test his strength, and he remembered the machine in his school's boxing club.

Coming to school again, Lu An went straight to the boxing club.

After explaining his intentions, the members of the boxing club agreed with him to test, after all, he was someone the president had admired and invited.

Arriving at the test machine, Luan tried to throw a punch.

Afraid of smashing the machine, Lu An temporarily withdrew most of the force before encountering the test machine.

Only one hundred and fifty pounds, a little embarrassed to look at the classmate who brought him to the test, Luan added a little strength, and swung another punch.

Seeing the three hundred pounds displayed on the machine, Lu An nodded with satisfaction and was about to leave.

The first punch retracted too much power, Lu An was a little overestimated of his strength, and the second punch did not exert all his strength, but it was finally not underestimated.

The key is that quenching skin is only incidental to the increase in strength, and it is called metamorphosis until blood refining and bone forging increase in strength.

The boxing club's worship of strength is very powerful.

As soon as the three hundred pounds came out, he instantly conquered the classmates who brought him.

The next moment, the classmate dialed the president's phone.

The impact of three hundred pounds, even if you participate in a normal boxing match, is very powerful, and you don't need to be limited to college leagues.

The president, who received the call, came again and sent an invitation to Lu An.

Originally, the school boxing club was connected with the boxing club outside.

Occasionally, there is an opportunity to invite outside boxing masters to teach, and they have also seen the strength of outside masters.

Three hundred pounds, even if it is placed outside, it is relatively strong.

This testing machine was originally sponsored by an outside boxing club, in order to find enough talent.

Most of those who can go to college are in decent condition, at least they are not short of nutrition, and their physical fitness can keep up.

In addition, educated boxers are still a little different from uneducated, and most of them have stronger learning ability.

The president of the boxing club arrived, and Lu An was also interested.

In addition to moving bricks on the construction site, the boxing club is also a good place to go.

If you can't win, you admit defeat, anyway, if you are a cultivator, you will generally not be killed by someone when you come up.

However, when you enter a boxing club outside, you should have professional training equipment and you can accumulate a lot of combat experience.

A practitioner with no background can only enter the Tao if he seizes every opportunity to improve himself.

After practice, Lu An found that he could cultivate and improve without entering the Dao, but since the official requirements for entering the Dao can only join, it shows that entering the Dao is still more crucial.

After improving your strength, it should be better to make friends with some cultivators who are relatively strong and have a complete lineage, and ask them for advice.

If he doesn't want to, Lu An can also use spirit stones to buy it, or use a little force to get what he wants to know.

All this is based on sufficient strength, otherwise it would not be possible.

Including the task of finding the source of goods, Lu An didn't think that cultivators were all easy to talk to.

Even if you find a source of goods, if you don't have the strength to maintain protection, you will soon lose it.

In a short period of time, Lu An still wants to hug the official thigh.

If you can pull the official banner, you will have a lot of confidence in doing things.

But the task of finding the source of goods, it is obvious that it cannot be carried out, from guessing who I am, it is obvious that it will be done anonymously, or that it will encounter very great resistance to complete it openly.
