After finishing the crazy shopping, Ian returned to the villa. Everyone else went to class, and the environment was undoubtedly very ideal. According to Li Xiu's instructions, Ian ran to his room, hung the door and locked it, and ran to the toilet and took out a huge wooden barrel.

"You must remember the order of these medicinal materials clearly. Once you put one wrong sperm, you will have the possibility of losing your life, so you must remember it clearly. Also, can you be faster and burn water so slowly."

After the water in the barrel had boiled, Ian gradually added various treasures of heaven and earth into the barrel in the order Li Xiu said. The color of the water gradually began to change, from colorless to green, and then turned red. In five minutes, after Ian put all the treasures of heaven and earth into it, the bucket of water had turned into a colorful color.

"Go in now and hurry up! Remember, after entering, you must immediately start to use the set of mental methods I taught you. Otherwise, you will probably die in all kinds of unbearable pain."

Ian ignored Li Xiu's complaints, because Li Xiu had repeated these things many times. Ian just put one foot into the barrel and felt a wave of heat. This surprised Ian. According to his physical strength, even a hundred-degree boiling water would not make him feel this way, but this bucket of water made Ian feel like he had become an ordinary person again. But at this time Ian couldn't care about that much, and gritted his teeth and jumped into the barrel.

After entering the barrel, Ian suddenly felt a terrifying heat coming from his whole body. It was not only a heat that penetrated into the skin from the outside, but also a heat from Ian's own body. It was like a ball of fire burning in your body while you were still in the sea of ​​fire.

"If you don't want to be burned to death, then you can immediately use your mind method!"

Under the reminder of Li Xiu, Ian quickly began to operate the mental method taught by Li Xiu. Before Ian had started to operate for five minutes, Ian suddenly felt a clear stream in his body, which began to reduce the fiery force and rage in his body. However, this clear stream lasted for less than a minute, and the effect was no longer obvious. The burning sensation in Ian's body appeared again, and this time, it was more intense than before.

If the fire before was burning in Ian's abdomen, Ian now felt that this sense of heat came out of his bones. The feeling that even the bone marrow was burning made Ian feel what it means to be in pain for the first time. However, Li Xiu did not give any prompts, which means that Ian had no other way except to use his mind and patience.

The pain lasted for more than an hour. At this time, the blue veins on Ian's forehead had already risen high, and the muscles on his cheeks showed that his master was gritting his teeth. Will there be a touch of red in the bucket? It was the blood that Ian had already clenched through his palms with his fingernails. At first, Ian thought that this pain would numb himself with the passage of time, but the warmer and higher temperature directly broke Ian's idea.

An hour later, Ian felt the high temperature gradually dropping, and he felt relieved. In fact, Ian also wanted to exhale a turbid breath with his mouth, but the masseter muscles that had been tense in his state made him unable to open his mouth at this time. This comfort of the high temperature did not make Ian feel comfortable for too long. When Ian relaxed his nerves, the temperature he was in had quietly dropped below zero. At first Ian didn't think anything was there, but he just felt that the cooling was a little quick.

But just one minute later, Ian felt an unusually biting cold, but at this time, it was still bright sunny outside the window.

Ice and fire body training. This is the first hurdle in the practice of Li Xiu to Ian. After the practitioner has experienced extreme flames, the feeling of frozen will follow. This body training method of alternating ice and fire is something that every person who practices this technique will definitely experience. Moreover, the alternating ice and fire will have nine reincarnations, a total of eighteen hours. In the history of practicing this technique, countless people have died on this first hurdle. After all, this feeling is not only perception from the outside world, but more from the body of the practitioner. Some people with poor physical fitness cannot withstand several rounds of such torture.

However, although ice and fire bodybuilding is very painful, it is also very helpful for the transformation of the practitioner's physical fitness. Once the practitioner introduces this technique, ice and fire bodybuilding can allow him to be immune to all ice and fire holy skills at the same level or even cross a large level. At the same time, ice and fire bodybuilding can also increase the toughness of the practitioner's body, whether it is in terms of bones, tendons, veins, or muscles, there will basically be a qualitative leap.

After enduring the extreme cold for ten minutes, Ian's body began to tremble without his control. In Ian's room, he could also hear a sound of upper teeth constantly tapping his lower teeth. Even on the surface of Ian's body, a very thin layer of frost could be seen, but under the sunlight, it was not very conspicuous, but it was more like Ian's skin was reflecting.

Ian felt that his eyelids were very heavy now, and his body kept telling him to sleep. As long as you fall asleep, you don’t have to bear these pains. As long as you fall asleep, all the severe winter will pass, and what greets you is the warm New Year. But every time Ian was about to be unable to help but want to fall asleep, he would use his last bit of perseverance to bite his tongue suddenly. The huge pain made Ian forcibly wake up from his sleep.

Although this is not a real cold place, Ian has a premonition that once he falls asleep, he may never wake up again in his life. This is not just a tempering of his body, but more a tempering of Ian's mental power. Once Ian's nerves relax, then there will only be one result waiting for Ian, that is death.
