On the second floor of the Book Pavilion, only students who have reached the blood coagulation realm or above can enter, and there is also a special teacher to supervise it. The teacher knows the books on the whole floor well, and the teacher in charge of the library can just ask what books the students want.

"Teacher, I want a thunder-based technique or combat skill that can harm itself, at least at the general-use level. There is also a copy of the water system. As soon as Chi Xiang arrived on the second floor, he made his own request to the teacher.

The teacher looked at Chi Xiang with strange eyes, there are all kinds of students in these years, but the students who want to harm themselves have really never seen it. "I said children, what are you doing at a young age? Do you have to harm yourself?" The teacher thought that Chi Xiang had the idea of committing suicide, so he was also ready to dissuade him.

"Teacher, I'm here for body refining, where do you want to go?"

The teacher breathed a sigh of relief when he heard this, so he said, "Then you just say that it would be better for you to find this auxiliary body refining technique?" Go to the head and turn right, there should be what you want over there." ”

Chi Xiang nodded and walked in according to the teacher's guidance. On the right-hand side is the combat technology area, which belongs to the restricted category according to the classification. This restriction class does not mean that it restricts others, but that there are certain restrictions on the cultivation of these exercises, just take the combat skills of a copy of "Thunder Fist" as an example.

This combat skill is to attach thunder and lightning to his fist, but the degree of thunder and lightning is also related to his own refining level, after all, it is necessary to ensure that this layer of thunder and lightning will not bring harm to himself, so people with a poor degree of refining are very unsuitable for this combat skill. Therefore, few people learn the restricted combat skills.

Chi Xiang saw the location of the thunder system combat skill at a glance, looked through them one by one, and sure enough, he found the combat skill that suited him, "Thunder Protection", which is a defensive combat skill, using thunder and lightning attachment to protect his internal organs and slow down the impact. Usually fight against those who are higher than their own cultivation, and are used to reduce the internal damage they receive.

However, the conditions for the use of this combat skill require that the user's own internal organs can withstand a certain degree of thunder and lightning power, otherwise the use of this combat skill will cause internal injuries to themselves.

Chi Xiang thought about it for a while and decided to use this technique first.

And Chi Xiang chose a combat skill called "Xuan Ice Shield", this combat skill and "Thunder Protection" both belong to the defensive type of combat skills, but "Xuan Ice Shield" belongs to defending against external attacks.

The two combat skills, one outside the enemy and one inside, can be used together. The reason why he didn't choose the fire attribute was because Chi Xiang found that the fire attribute really didn't have defensive combat skills, and if you want to talk about defense, the fire spirit root is basically alchemy, but it's obviously not something that can be learned now.

As for the attack skills, I haven't learned my own Razer Draw and Ice Seal yet, so it's not necessary to get too much for the time being.

"Teacher, I want to take these two battle skills!" Chi Xiang took out the selected battle skills.

The teacher looked at the two battle skills, and his face couldn't help but show a trace of disdain, because in this world where strength is supreme, everyone advocates offense even more, and only those cultivators who are afraid of death will learn a lot of life-saving tricks.

And cultivators who are afraid of death often won't have any great achievements in the future, just this little kid said that he was going to harm himself? Who is fooling? I'm afraid he is more afraid of death than anyone else, right? When the time comes, it's good that he really fights, and he won't be scared to pee his pants!

"Good. The teacher didn't say much, just registered casually, and then sat down again.

After getting the exercises, Chi Xiang naturally tried to train as soon as possible, anyway, he would report to the new class tomorrow, so naturally he would use the rest of the day to improve his strength as much as possible.

"Thunder Protector, it's you!" Chi Xiang decided to practice the thunder system first, and if it went well, he could also help him improve the level of the exercises of refining his body.

Chi Xiang followed the requirements of the exercises, and gradually released his thunder and lightning power from his own thunder spirit root, and gradually followed each blood vessel towards the position of the internal organs of the conveyor tract. Next, you need to use the power of thunder and lightning to wrap your internal organs, but Chi Xiang can't do it anymore. A mouthful of blood suddenly spurted out, obviously hurting himself while running the exercises.

Because the strength of Chi Xiang's internal organs is not enough to withstand the voltage of the power of thunder and lightning, it causes internal bleeding, but fortunately, the power of thunder and lightning has not been transmitted to the heart, otherwise he will be killed at this time.

Sure enough, there are too many things that a layman doesn't understand in cultivation, maybe because of some hidden dangers, he will fall on the road of cultivation. I hate that I don't have the guidance of an old man who has no ring, and I don't have any memory inheritance of ancient powers, everything has to be explored little by little.

Some people may think that Chi Xiang is stupid, why don't they ask the teacher or the dean in advance? Chi Xiang himself couldn't imagine that his body cultivation could not withstand the power of thunder and lightning, so naturally he didn't know how to ask people.

Fortunately, the impact is not great, and after taking the healing pill, the injuries in the body will be stopped, and it will take a few days to turn around and dissolve the blood congestion in the body.

After this accident, Chi Xiang specially searched for relevant literature. Only then did I know that the cultivation of the viscera had only begun in the Blood Coagulation Realm. Moreover, there are many kinds of physical exercises, and the main schools are internal cultivation, external cultivation, and internal and external cultivation.

Internal cultivation is based on the cultivation of the internal organs, supplemented by the meridians, and this school advocates the key to protecting oneself, as long as it ensures that oneself does not die easily, which is the ultimate goal of physical cultivation.

Outer cultivation, on the other hand, is the cultivation of skin, flesh, muscles and bones, and this school of thought tries to make the body of physical cultivation invulnerable, using the body as a shield and the hand as a knife to break the enemy with strength.

As for the internal and external cultivation, it is naturally a synthesis of the two, trying to strengthen itself more comprehensively, but so far, the practice of internal and external cultivation has been criticized more than that of the other two schools. Not to mention the scarcity and preciousness of the exercises, the main reason is that his exercises have too many conditions for cultivation and the goals are too scattered, which will cause the exercises to be unattainable. The cultivators who can truly cultivate both inside and outside are all geniuses who save one in a million.

And Chi Xiang's exercises belong to the external cultivation stream, tempering the skin, flesh, muscles and bones with thunder tribulation, so it does not help much for the baptism of the intestines and meridians. Therefore, when he was practicing "Protecting the Intestines with Thunder", the power of thunder and lightning had just touched the internal organs, which brought internal injuries to Chi Xiang.

Therefore, even if Chi Xiang learned to protect his body from thunder, he would not be able to improve his body refining technique through this combat skill. So it's just an ordinary life-saving skill at most.

It seems that this skill will have to wait for him to reach the peak of the Blood Condensation Realm before trying it, and this skill can only be lent for a week, and the time is limited. Therefore, Chi Xiang had no choice but to memorize all the operation processes of the combat technique in his mind, so that as long as the quality of the viscera met the requirements of the exercises, he could use it directly.

The rest of the time lasted and was not idle, after all, there was still a book of combat skills, and Chi Xiang used the remaining time to gradually master the Xuanbing Shield and release it.

Although the size of the shield is currently only the shape of a hand shield, and the degree of sturdiness is relatively limited, it doesn't matter, it will gradually be solved when you become familiar with this exercise.
