Mental power is different from Yuan force. Compared with Yuan force, mental power attacks are more subtle. Just like a big black dog suddenly attacking Su Yue, Su Yue didn't notice it beforehand. It wasn't until the severe pain in his body that he knew he was being attacked. Therefore, if there is no precaution in advance, mental attack can be said to be a sneak attack weapon. Even a cultivator who is much stronger than himself will still have the opportunity to rely on mental power to sneak attack and kill the opponent. Half an hour later, Su Yue's body had almost recovered. The second wave of the big black dog's mental power hit, and Su Yue roared in pain again and curled up on the ground. As night fell, after Su Yue persisted in being mentally attacked five times, he finally couldn't bear it anymore, so the big black dog stopped and let Su Yue rest. Three days later, Su Yue relied on the help of the small vitality formation to successfully improve his level from the fourth level of body tempering to the fifth level. Practicing for four hours every day consumes exactly one first-grade blue spirit stone. When he entered the fifth level of body tempering, the speed of converting Yuan Qi in his body increased a lot as expected, but Su Yue did not extend the time for absorbing Yuan Qi. The big black dog said that greedily absorbing vitality in a short period of time will make you regret it when you enter the realm of spiritual nourishment. After several days of training, Su Yue's physical strength has obviously improved. On the fourth day, he could withstand ten mental attacks from the big black dog. Seven days later, Su Yue's level reached the sixth level of body tempering. This strength, considering Su Yue's age, is considered to be above average in Rose College. The number of times Su Yue's body withstood mental attacks also increased by leaps and bounds to thirty. Su Yue is also quite satisfied with this effect. After this kind of exercise, Su Yue can clearly feel that his body is much stronger than before. Su Yue stayed in seclusion for twenty consecutive days. "This is the last piece." He held a first-grade blue spirit stone in his hand. At the trading center, Su Yue purchased a total of twenty pieces of first-grade blue spirit stones, and almost all of them have been consumed by now. Using this vitality array to practice and absorb vitality is fun, but it also consumes a staggering amount of money. A piece of first-grade blue spirit stone is worth one hundred gold coins. "However, I can feel that my realm is not far from the seventh level of body tempering. Returning to the peak is about to be achieved." Su Yue, holding the blue spirit stone in his hand, his eyes became brighter. Breaking through from the sixth level of Body Tempering to the seventh level of Body Tempering is a small hurdle. Even if Su Yue relied on the vitality formation, he had to practice for more than ten days before he could touch that layer of membrane, which shows how difficult it is. If you don't have this vitality formation and want to return to the seventh level of body tempering, you don't know how much time it will take. Su Yue embedded the last blue spirit stone into Wanluo Jade. "Suck!" Feeling the gathering vitality, Su Yue used the Heavenly Thunder Mental Technique to absorb it with all his strength. A few hours passed in a blink of an eye. "Condensate! Condensate for me!" After absorbing the energy, Su Yue did not get up, but immediately activated the energy in his body to flow towards his abdomen. The powerful and surging vitality quickly surged into the abdomen through the eighty-one meridians, and then rotated in the abdomen at high speed. ? One by one, dark blue balls appear slowly as time goes by. One, two, three The number of dark blue Yuanli balls continues to increase. "Seven!" With a bang, Su Yue's eyes suddenly opened, and divine light suddenly appeared, as bright as a bright star. "Successful!" When the seven dark blue Yuanli balls turned into Yuanli again, Su Yue exhaled, and the gas that could not be seen with the naked eye actually came out of Su Yue's mouth like a white mist. After being spit out, it stayed for a long time to breathe, and then slowly dissipated. "Haha!" Su Yue stood up and clenched his fists lightly. A feeling of surging power was born naturally. This feeling is like a punch that can break a mountain. A single strike of the palm can cut off a large river. "Four years ago, I stepped into this realm, and now, I'm back. I, Su Yue, will go further." Su Yue said in a deep, slow and powerful voice. "Su Yue, it's time to strengthen your body." At this time, the big black dog appeared again. When he heard these words, the arrogant Su Yue's expression suddenly weakened a lot. "Ah!" "Come again!" The twenty days of strengthening were indeed not in vain. When Su Yue took off his cyan robe, the lines of his muscles were much deeper than they were twenty days ago. Su Yue didn't look very strong, but his whole body was filled with an explosion of power. "That's good. Now you can withstand my level of mental stimulation a hundred times a day. You should keep up your efforts."?The big black dog nodded and said with satisfaction. Su Yue lay on the ground and used all his strength to stretch out his trembling arms and wave them. "Boy, your body is much stronger now than before. If you don't believe me, try stabbing you with a sword." The big black dog said with a sinister smile. Su Yue¡¯s eyes widened and he shook his head decisively. The next day, when the sun rose, Su Yue stood up from the bed and touched his chin. All the fatigue from yesterday has been wiped away. "The blue spirit stone is gone, and this vitality formation cannot be used for the time being." Su Yue looked at the Wanluo jade beside him, which he had packed in a cloth bag, and shook his head. "Hey, let's go to the third-level vitality formation in the academy. Although it only lasts for an hour, and although the effect is very poor, no matter how small the mosquito is, it is still a piece of meat! It is better than me, absorbing vitality in this ordinary space." Su Yue Thinking in his mind, he walked out of the room and stepped out of the small courtyard. "Su Yue!" The martial arts arena was still quite lively. Although it was still early, many people had already arrived at the martial arts arena to practice martial arts or strengthen their bodies. Seeing many students using primitive methods to strengthen their bodies, Su Yue felt extremely proud. He suddenly discovered that although his strengthening methods were a little more painful, they were still much more effective than those using primitive methods. At this time, a clear voice came, it was Fang Yue. "Fang Yue." Su Yue looked at Fang Yue, who was wearing a purple dress, and said with a smile, "I haven't seen you recently. Have you gone to find Mr. Hua?" Mr. Hua originally asked Fang Yue to take the time to find you. he. "No way!" Fang Yue waved his hand, "He said that Su Yue, you are a mess, how could I go to him? I have been practicing in seclusion recently, and I have just broken through to the fourth level of body tempering. Su Yue, you Have you entered the fourth level of body tempering?" A cute smile appeared on Fang Yue's pretty face. Su Yue smiled and said, "That's almost it." "Brother Su Yue!" A voice came from one side. Su Yue turned around and saw a young man about fifteen or sixteen years old walking over with a chuckle. The boy's name is Zhang Kai. Four years ago, Su Yue and Zhang Kai were very good friends, and Zhang Kai always called Su Yue his brother. Although Su Yue later declined in strength, Zhang Kai's respect for Su Yue never changed. "Zhang Kai, long time no see?" Su Yue was also enthusiastic when seeing Zhang Kai. Su Yue¡¯s strength has declined and he has become a third-class student, while Zhang Kai is a second-class student. Since they do not practice together, they have few opportunities to meet each other. In addition, everyone is busy practicing. If you slack off a little, you will be surpassed by others, so naturally you don't dare to waste too much time. "Brother Su Yue, it's great to hear from Fang Yue that your strength is recovering recently. I knew that Brother Su Yue would definitely return to the top." Zhang Kai said sincerely. In his heart, he was indeed happy for Su Yue. When Su Yue's strength declined, he even made a special trip to ask the elders in his family about the reasons for the decline in strength, but he did not get the ideal answer. Regarding Zhang Kai's concern, Su Yue also felt a warm current in his heart, and nodded heavily to Zhang Kai, good brother. "Huh?" "Isn't this Zhang Kai?" A harsh voice came in, making both Su Yue and Zhang Kai frown. "Haha, who did I think it was? It turns out that Su Yue is here too. Zhang Kai, you are really worthless. After so many years, you have not made any progress at all. You can still have such a lively chat with a loser." The student who spoke , laughing loudly. The other students on the martial arts field also noticed the situation here and looked over. Su Yue raised his eyebrows and slowly scanned the student's face. Su Yue was no stranger to this student. When he entered the seventh level of body tempering at the age of twelve, this person was also running around him, calling him Brother Su Yue in a friendly manner. But now, this person has turned into this kind of face. Su Yue only regrets that he was blind and couldn't see the true face of this kind of person. He didn't help him less. This student, named Liu Chong, is one or two years older than Su Yue. When Su Yue's eyes swept over Liu Chong, his eyes narrowed slightly and his body shook slightly. Another familiar face appeared next to Liu Chong. Seeing this beautiful face, the scenes that happened four years ago flashed through Su Yue's mind quickly, as if everything happened yesterday. The student standing next to Liu Chong is a woman named Zhao Linger. Four years ago, Su Yue and Zhao Ling'er, who were similar in age, had entered and exited Rose College together. They were the golden boys and girls in the eyes of many people, and many people believed that the two would eventually get married. However, when Su Yue's strength declined, thenZhao Ling'er's woman left Su Yue's side without any hesitation. She didn't even have the patience to wait a moment. At this time, she was standing next to Liu Chong. With her beautiful eyes, she just glanced at Su Yue and others, and then quickly turned away, as if she had never recognized this person. Facing such an expression, Su Yue also had a sneer on his lips. Su Yue saw disdain and arrogance in the other party's eyes. At this moment, the other party may not even have the thought of saying hello to me, right? "Haha." Su Yue smiled mockingly and suddenly wanted to leave here. "Liu Chong, what are you talking about? Brother Su Yue will definitely be able to return to the top soon." Zhang Kai glared at Liu Chong and said angrily.
