After a few circles in the space with satisfaction, Zhang Yuan put away the Nine-Clawed Divine Dragon, found a flat stone platform by the waterhole and sat down, and entered the state of cultivation one after another.

Time passed slowly, and finally ...... When the time was close to early morning, Zhang Yuan woke up the two girls, drove the nine-clawed dragon, and sent them back to the crescent crescent bend, although this space is some distance from the crescent bend, but with the ability of the nine-clawed dragon, and it is underwater, this distance is only a matter of more than a minute, very close.

After sending back the two girls, Zhang Yuan touched back to the living quarters, which had just been brightened, so Zhang Yuan returned to the bunk, pulled the quilt to cover his body, and fell asleep deeply.

When Zhang Yuan woke up again, there was no one in the residential area, and at the same time, there was a chaotic sound of footsteps in the corridor outside the residential area, which was obvious...... It's time for class.

Looking at the time, it was only more than two hours since Zhang Yuan fell asleep, but unexpectedly, Zhang Yuan's spirit was very good, he didn't feel sleepy at all, under the cool energy in the Dragon Ball, not only the fatigue was swept away, but even the spirit was very good, and he didn't dare to continue to lie in bed, Zhang Yuan hurriedly got up, and after washing up, he rushed to the school, today's class can't be late, Professor Gu Yang Hongyun said that today I will teach you the cultivation method of the human body! In this way, you can improve the strength, strength, agility and other elements of the human body, and most importantly, in this way, you can greatly improve the soul power and spiritual power, and these two have too much effect on the dragon.

After eating breakfast and resting for a while, the morning class finally began, although there was a roaring noise from the construction site not far away from time to time, Zhang Yuan calmed down, listened carefully to every word that Professor Yang Hongyun said, and carefully sorted out the relevant notes.

Facing the apprentices in the audience, Professor Yang Hongyun said: "What I want to teach you today is a kind of mental method that can greatly improve spiritual power and soul energy, and can greatly increase the power of the dragon earth. ”

The Heavenly Dragon Heart Sutra can produce a kind of qi in the body, this kind of qi is not the energy in the Dragon Ball, but belongs to the energy of the human body itself, under the explanation of Professor Yang Hongyun's master, Zhang Yuan was simply dumbfounded, this Heavenly Dragon Heart Sutra, and his own research is completely different from the concentrating on the Yuan, first of all, this kind of mental method can actually produce its own energy, and secondly, it ...... This kind of mental method mainly exercises the brain, and this is exactly what Zhang Yuan's exercises have not designed.

This Heavenly Dragon Heart Sutra seems to be a brick created to increase the power of the dragon, and if you want to increase the power of the dragon, you must consider it from the aspect of spirit and spiritual attack waves, so ...... The entire Tianlong Heart Sutra is aimed at the exercise of the brain part.

After taking a strong breath, Zhang Yuan closed his eyes, and slowly released the energy in the heart, accompanied by every jump of the heart, a blazing energy, gushing out from the heart, entering the acupoint in the meal, after a period of warmth, ascending along the meridians, passing through the guò against the tongue of the upper jaw, going up to the brain, using the method of the Tianlong Heart Sutra to warm up for a period of time, arriving at Baihui, and then descending down the spine, all the way to the feet and then flowing backwards to the perineum, into the lower dantian, after a period of warm recuperation, return to the middle dantian, and then flow back to the heart.

After a week of tentative operation, Zhang Yuan did not feel any discomfort, and after the warmth and accumulation of the middle dantian - the middle dantian - the middle of the diet, the upper dantian - the hundred meetings, and the lower dantian, a trace of weak energy has appeared in Zhang Yuan's body, and the brain is exceptionally clear and sober.

Overjoyed, Zhang Yuan wanted to continue cultivating, but unfortunately, the noon break had already arrived, and he had to go back to class, so he ...... Zhang Yuan had to get up and rush in the direction of the school.

However, what Zhang Yuan didn't expect was that as soon as the class started in the afternoon, Professor Yang Hongyun took everyone to the grove under the hill, and motioned to everyone to sit down and not make a sound.

From here, it can be seen what a person's qualifications are, most of the apprentices can't sense the energy of the heart at all, let alone release it, they can't even feel it, how to release it?

Originally, Zhang Yuan would not have been so smooth, but after cultivating for so long, he felt extremely sensitive to the energy in his body, and his foundation in this regard was far from being comparable to these apprentices.

After an afternoon of training, a small thin air flow had accumulated in Zhang Yuandi's body, which was formless and colorless, and could only be sensed by his divine sense.

After school in the evening, Zhang Yuan had dinner, rushed all the way to the waterhole in the forest, worked cross-legged, practiced the Heavenly Dragon Heart Sutra, and did not summon the nine-clawed divine dragon until more than nine o'clock in the evening, and then summoned the nine-clawed divine dragon, passed through the underground river, and rushed towards the earth.

After receiving the two girls, Zhang Yuan drove the nine-clawed divine dragon and rushed to the underground space that only belonged to the three of them, and along the way, Zhang Yuan learned from the two girls that they also started their official classes today, and also learned the Tianlong Heart Sutra.

After arriving at the cave, the three of them talked and laughed for a while, and then they sat cross-legged and began to practice the Heavenly Dragon Heart Sutra.

In the next month, Zhang Yuan and the two girls spent almost all of their time on cultivation, and after a month of cultivation, Zhang Yuan and the two girls reached the Xiaocheng realm at the same time!

The stronger the spiritual power, the faster the speed of cultivation, after all...... Energy is driven by spiritual power, and the stronger the spiritual power, the faster the energy will run.

At first, Zhang Yuan was also confused, but soon ...... Zhang Yuan understood that the reason why he cultivated so quickly was because of his improved mental method.

In fact, what Zhang Yuan and the two girls practiced could not be said to be the same set of mental methods at all. In other words, Li Jubing and Xiaobai's cultivation method is incomplete, so it has formed today's results.

Zhang Yuan also thought about passing on this set of exercises to the two girls, but in the end he dispelled this idea, not that he didn't want to teach it, but that this set of exercises is not complete at all now, and it is still in the stage of exploration, and it may go wrong at any time, and it is ...... The Heavenly Dragon Heart Sutra has only learned the beginning, and no one knows what will happen next.

The Heavenly Dragon Heart Sutra is divided into six volumes, and now Zhang Yuan and what they are cultivating are only the first volume, and only after reaching Xiaocheng, they can only get in touch with the second volume, although the cultivation speed of the first volume and the cultivation effect are really good, but it does not mean that the second volume is the same, let alone the third volume.

After a month, the three of them not only reached the realm of Xiaocheng, but more importantly, with the efforts of the three of them, a beautiful wooden house was finally built by the waterhole in the underground space.

This wooden house is very chic, there are a total of four rooms, which are three closed cultivation rooms, one for each of the three people, and then a large bedroom for sleeping.
