Ning Tiantian took out a jade slip from the storage ring, he scanned it with his spiritual power, and the first thing that came to mind was the eight big characters of "Cultivation Realm Spell Collection", followed by the content catalog. It first explains the principles of the use of various spells, then explains some methods of basic spells, and explains the requirements and methods of more than 100 cases of advanced and complex spells, and finally some research experiences of the original owner of Benyu Jian.

After reading the catalog, Ning Yitian saw: "Opening: There are many cultivators in the universe, countless cultivation methods, and the cultivation groups are also very different, but the fundamental purpose is to prolong life and become stronger. After entering the universe of the Cultivation Realm, I found that some spell application techniques in the Cultivation Realm Universe have great reference and research value even in the Cultivation Realm Universe, so I traveled around many places to find various spell skills in the Cultivation Realm universe, and wrote this jade slip for the purpose of deliberation and understanding. ...... There is chaotic energy in the universe, but it is extremely difficult for ordinary cultivators to obtain it directly. Chaos is divided into five elements: metal, wood, water, fire, and earth,...... The universe evolves and the stars change, producing four attributes: light, darkness, electricity, and magnetism,...... Taking a water-based physique cultivator as an example, this cultivator's body is mostly water aura, and the cultivation of water-based spells can be directly condensed and excited, and other spells can generate corresponding aura activation spells through the principle of the five elements, and its power will be weakened according to the different phases, for example: the power of water-based spells is 100%; through the principle of aquatic wood, it is good to activate wood-attribute spells that can reach 80%; wood regenerates fire, so water-based spells can also cast fire-based spells, but because water overcomes fire, the power of fire-based spells will be less than 10%; fire gives birth to earth, and earth overcomes water, and it is even more difficult to cast earth-based spells, and the power of spells will be less than 1% of that of water; Of course, it also depends on the wisdom and experience of the person who casts it, if the mentally handicapped water cultivator can learn the gold spell is not yet known, even if he learns it without hard practice to increase his experience, the gold spell is also weak,...... Water attribute physique cultivators are like dragons returning to the sea in the water, and their cultivation will also get twice the result with half the effort, and the power of spell casting will be doubled,...... The three states of water: gaseous water, liquid water, and solid water, can also be called: water vapor, water, and ice. Gaseous water is easy to use cloud and mist spells, which is useful for stealth and concealment; liquid water is ever-changing, many and surging, few and trickle, and there are many kinds of spells; solid water is strong and powerful, and can attack spears and defend shields, and spells are extremely powerful. ......”

Just a lot of in-depth explanations at the beginning, which benefited Ning Yitian a lot, and also gave him a certain understanding of spells, he continued to look down, and soon found the content about the retreat: "The cultivator's retreat technique is a method of using one's own aura to integrate into the surrounding matter through a special method and be able to escape with the help of unhindered movement after integration. As mentioned in the opening chapter, it is easiest for a water attribute cultivator to perform the retreat technique in the water, and it is the most difficult to perform the retreat technique in the soil. The aura in the cultivator's body must first emit a layer of shield to protect the body, and then emit another layer to simulate the properties of the matter in the surrounding environment, and the specific method of simulation is ...... Here, cultivators need to pay attention to the fact that the spiritual energy reserves in the body should not be too low, otherwise if they can't escape from the escaped substance before the spiritual energy is exhausted, they will likely be squeezed to death. ......”

Ning Yitian was working hard to learn the art of escape in the closed room, but Ouyang Ran in the outside world was in a huge crisis, after the missile attack of country R, a large number of warriors were airlifted to the vicinity of the capital of country Z and began to arrest or kill the warriors in the capital. Ouyang Ran was quickly captured by the warriors of country R due to his low realm, and on the evening of September 2, more than 50 warriors were captured like Ouyang Ran, and these people were concentrated in a secret place, and after dark, a military transport helicopter transported these captives to a biological experiment base in country R, these people were first sealed with memories, implanted with biological computer control chips, and then injected with mutant genetic modification liquid, and then trained after the transformation was successful, and after the training was completed, they became the killing machines of country R.

Ning Yitian was originally smashed and injured for a total of three days in a coma, during which Ouyang Ran had been successfully transformed, and after the training was completed, he would become a humanoid killing machine.

The learning process is monotonous and boring, but Ning Tianyi is different, he has always been very interested in learning, or he would not have read 30% of the books in the school library. Another three days, Ning Yitian will learn the theoretical knowledge of the retreat technique, the rest is his practice process, because there is nothing else in the closed room, Ning Yitian can only try to practice Jin Dun, he will put a layer of metallic aura outside the body to form a body shield, and then feel the metallic characteristics of the alloy on the floor of the closed room, and finally he released the aura of the simulation attribute through his right hand, slowly, this hand pressed into the floor, and the floor seemed to be connected.

Five days later, on September 13th, Ning Yitian had mastered the method of being able to escape into the walls of the closed room with his whole body, and then he came up with a way to use the storage ring to collect soil from the soil layer outside the dungeon, and continued to practice the earth escape, then practiced the water escape, and then took out the furniture collected from the rental room from the storage ring, practiced the wooden escape, and then burned the furniture to practice the fire escape. Ning Tiantian's learning talent was undoubtedly terrifying, he only spent ten days to learn the last four escape techniques, although it was still very reluctant, but after all, he had already learned it, and it was only a matter of experience in the future.

"During this time, they didn't come to blow up my Floating Cloud Shuttle's body protection mask, I don't know what conspiracy they have, hmph, I'll go out first, there is electromagnetic interference here, and the biological computer can't be connected to the Internet to query the outside world, and Ran'er doesn't know what's going on. Ning Yitian was a little worried about Ouyang Ran's situation, after all, she was only put in a small forest on the outskirts of the capital at that time, and she hadn't been in contact with her for so long, would she go to the capital to find him again, and she would definitely be anxious if she couldn't find him at that time, maybe she would think he was dead,...... The more he thought about it, the more worried he became, "Regardless of whether the escape technique is practiced or not, I will escape today." He made up his mind.

Ning Tiantian took out the biological computer from the storage ring to check the time, and set an alarm clock until two o'clock in the morning, and then began to meditate to restore the body to the best state.

At two o'clock in the morning, the time to escape came, he slowly sank to the floor, the whole person was still found after all sinking, the dungeon sounded a piercing alarm, Ning Tian did not dare to delay, quickly sank to the depths of the ground, he used his mental power to find that there was a dark river underground, he was going to flee to the dark river at this time, and then flee along the dark river to a distance, and finally escape from the ground at a distance from the dungeon.

"Peng, Peng ......" The warrior who was in charge of guarding them on the dungeon found Ning Yitian who had escaped to the ground, he used his knife qi to slash the ground of the closed room where Ning Yitian had stayed, and soon a big hole appeared, and he continued to blast towards the soil on the ground, but the speed at which Ning Yitian escaped was faster than the speed at which he made the hole, but this martial artist continued to chase Ning Yitian without giving up.

"Damn, you won't lose a piece of meat if I run away, do you need to be so dedicated. Ning Tiantian was very depressed, he initially thought that this martial artist would give up chasing him after escaping underground, after all, it would take too much effort, but he miscalculated, he didn't expect this martial artist to be so persistent.

"Fight" Ning Tian stopped fleeing towards the underground dark river for a day, and changed to fleeing forward, after all, in the dirt, he was faster than the warrior who hit the hole, if he went to the dark river, his escape speed would not be as good, and he would definitely be caught.

"It's not good, the aura is about to run out" Ning has been performing the escape technique non-stop for a day, coupled with the unskilled use, the aura in the body is consumed quickly, he took out the best spirit stone from the beginning to recover, but the recovery is far from catching up with the consumption, "insistence" Ning Yitian silently cheered himself in his heart.

Ning Yitian escaped in order to save aura, the body protection aura on his body became less and less, and the heavy squeezing of the soil made him feel more and more difficult to move his body, gradually, the muscles of his body began to sore, the bones began to gurgle, and his consciousness gradually became a little blurred, "You can't faint." Ning Tiantian bit the tip of his tongue hard, and a sharp pain came, and his body that was depleted of spiritual energy was still holding on with an unyielding will, and slowly escaped forward with a little spiritual energy recovered from the best spirit stone, and the martial artist behind "Peng, Peng ......" had already transformed into a monster, and the speed was much faster, and it was only more than 100 meters away from Ning Yitian, "Ah——,ah-" Ning Yitian roared a little unwillingly, all the points in his body began to rotate at high speed in his unwilling roar, and one by one the aura devouring holes began to operate, and in the roar, Ning Yitian frantically gathered hundreds of thousands of cubic meters of spiritual energy around him, "Huh, Huh......" Bursts of aura quickly gathered and produced a violent wind, and a hundred-zhang high aura tornado gradually formed on the ground where Ning Yitian was, and these aura seeped into the soil layer and directly reached Ning Yitian's side, and the tricks opened on his body frantically devoured these aura.

In his unwilling will, Ning Yitian finally opened the channel for the advancement of his body cultivation and began to enter the seventh layer of the foundation building period. There is a hurdle from the sixth to the seventh layer of the foundation building period, which is a barrier for the middle of the foundation building period to enter the late stage, and after the cultivator reaches the late stage of the foundation building period, some spells that consume less spiritual power can be learned and cast. The reason why Ning was able to learn the retreat technique in the sixth layer of the foundation building period in one day was because his mental cultivation had already reached the peak of the Jindan stage (he himself didn't know the height, and there were also obstacles to the growth of his mental cultivation, and these barriers were the excessive realms of each cultivation period, and it was difficult for ordinary epiphany to break through these barriers. The second is that he used the best spirit stone to restore the consumed aura from the beginning, so he can not only learn and perform the escape technique, but also increase the distance he escapes a lot because of the recovery.
