It is worth mentioning that there is only one bed in the big bedroom, but when sleeping, Li Jubing sleeps in the middle, Zhang Yuan is on the left, and Xiaobai is on the right.

After the Tianlong Heart Sutra was Xiaocheng, Li Jubing and Xiaobai came forward, and Professor Xiang asked for the second volume of the Tianlong Heart Sutra and began to cultivate, and learned from the professor that the three of them were still the first three apprentices of the entire grade to reach Xiaocheng.

The content of the second volume of the Heavenly Dragon Heart Sutra is not about the operation of energy, but about combining the energy generated by itself with the energy in the Dragon Ball and fusing it into new energy.

When Zhang Yuan controlled his soul and sank into the world inside the Dragon Ball, when he looked closely, those origin energy balls that had absorbed their own energy all emitted purple-blue light, like twinkling stars, while those origin energy balls that did not absorb their own energy, although they were still purple and blue, did not emit any light.

The Heavenly Dragon Heart Sutra has no limit, the origin energy ball is like a circular container, and I don't know how much energy it can hold, for now, it is far from seeing the limit.

For the second volume of the Heavenly Dragon Heart Sutra, Zhang Yuan once again had a strange idea, since all the energy will eventually merge with the energy in the Dragon Ball, then why not directly input the energy into the Dragon Ball at the end of the mental method, and let the energy in the Dragon Ball absorb it by itself?

With this idea, Zhang Yuan changed his mind again, and the energy was radiated from the heart, but in the end, it did not return to the heart, but was sent directly into the Dragon Ball.

After a try, it was completely feasible, rotating around the body, after the warmth of the upper dantian, the middle dantian, and the lower dantian, all the energy flowed into the dragon ball, and for a while, the entire dragon ball emitted a brilliant light.

In order to verify whether this method was feasible, Zhang Yuan ran for a few weeks, and then sank into the Dragon Ball with his soul, and sure enough, it ...... As Zhang Yuan thought, when the energy entered the Dragon Ball, all the energy sources automatically began to absorb the free energy in the space, and the absorption was very even, and each origin energy ball was faintly lit up.

So far, what Zhang Yuan has cultivated can no longer be regarded as the Heavenly Dragon Heart Sutra, the Heavenly Dragon Heart Sutra is only a part of the exercises he has cultivated, and the entire exercises are put together, and he should combine his own fusion and induction of the Heart Sutra with the Heavenly Dragon Heart Sutra, and Zhang Yuan's name is the Yuanlong Heart Sutra.

After a whole month of hard cultivation, it finally ushered in a monthly vacation once a month, the life of Tianlong Martial Arts is very tense, and the cultivation is also very hard, so at the end of each month, there are a few days of vacation to let the apprentices adjust their mood.

After a month, the three of them finally left Wumen again and returned to the small building that Zhang Yuan had newly bought. As far as the eye can see, the walls around the small building have been newly painted, the gate has been replaced with a new one, and the flower lawn planted around the small building has begun to sprout, and everywhere is green.

Not only that, but even the exterior wall of the small building has been newly painted, and from a distance, it looks like a new small building, snow-white and very eye-catching.

Especially in the backyard, a chic sandalwood building stands among the green flower seedlings, secluded and elegant, which makes people can't help but like it at a glance.

Entering the small building, Sister Wang and the three maids lived on the first floor, while Zhang Yuan and the two girls' rooms were on the second floor of the small building, and the basement of the small building was also opened up, and four silent cultivation rooms were built, Zhang Yuan, Li Jubing, Xiaobai, and Wang Daqiang each one.

As soon as he returned to the small building, after Zhang Yuan settled the two girls, he immediately rushed to the wooden small building in the backyard.

In the small wooden building, the colors of many water system energy fields are close to and similar to purple blue, and it is extremely difficult to distinguish, but after having the gathering energy array, it is much easier.

Under the action of the Gathering Array, the purple-blue earth energy was fixed in a small area, forming a vortex air flow, no matter how close the other colors were to the violet-blue, although they were not static, but the speed of the flutter was very slow, and it was by no means rotating.

Sitting in the center of the vortex, one after another dragon-shaped air currents rushed out from all over Zhang Yuan's body, rushing towards the purple-blue water system origin energy that swirled around his body, and the speed was amazing.

Finally, after absorbing the energy in the surrounding space, Zhang Yuan slowly opened his eyes and looked at Master Jesse excitedly. Although this gathering array is still very rudimentary, it can only double the elemental density, but it is enough! With the environment in the upper and underground rivers, Zhang Yuan's cultivation speed couldn't slow down no matter what.

As soon as he opened his eyes, Zhang Yuan said excitedly: "It's a success, it's really a success!" What do you think...... Can the energy of other departments also stimulate this formation? ”

Hearing Zhang Yuan's words, Master Jesse nodded categorically and said, "Yes, of course!" No matter what kind of energy it is, as long as it is input into this impulse crystal, it can be excited,"

Taking a big breath, Zhang Yuan's eyes suddenly lit up, he knew exactly what this formation meant, after having this small formation, everyone's cultivation speed would be doubled, and if he built his own base in the future, he could also let all members enjoy such treatment.

Moreover, this is only the initial formation, as Jesse studies it masterfully, this formation will definitely continue to improve its efficiency, it is only doubling now, and it will definitely increase more in the future.

After thinking about it, Zhang Yuan said excitedly: "Master Jesse, this kind of formation, you prepare four sets for me first, and I will take it to the Martial Sect, this thing is really amazing,"

In the face of Zhang Yuan's request, Master Jesse nodded happily and said, "No problem, four sets, right?" I'll get it for you in a moment, but ...... There aren't many of these white stones,"

Hearing Master Jesse's words, Zhang Yuan was stunned for a moment, and then said, "Do you have to use these white stones?" It can't be replaced with other materials,"

Shaking his head, Master Jesse smiled bitterly and said: "No, absolutely not, this stone contains wonderful energy, only this kind of energy can stimulate this formation, other energies can't,"

Scratching his head, Zhang Yuan said helplessly: "Okay, if it really doesn't work, we can only hire a team to help us transport some over, but I personally think that it is best to find a replacement, which is very important, after all, ...... We can't always carry these stones, right?"

Hearing Zhang Yuan's words, Master Jesse frowned and said, "I'm afraid this won't work, I've already tried it, and if I continue to study this, it will definitely be very time-consuming, and ...... Even if you can find an alternative material, you have to buy it or find it, so why not use it directly."

The benefits of using this material are still many, and this material, which is everywhere in the Wild Sand Valley, can be described as inexhaustible, and it does not cost a penny.

Facing Master Jesse's opinion, Zhang Yuan thought for a while, then nodded categorically, agreed, and left it to Master Jesse to decide on the research aspects, after all, Master Jesse is only one person, and it is impossible to study all the topics in detail.

After thinking about it, Zhang Yuan pondered for a while...... Zhang Yuan raised his head fiercely, looked at Master Jesse and said, "Master Jesse, I want to ...... Isn't it time for you to take two apprentices? ”

"With an apprentice?" Hearing Zhang Yuan's words, Master Jesse looked confused.

In Master Jesse's opinion, he is just a strange old man who likes to study some strange things, and what he studies is just some scenes in nature, and Master Jesse is just looking for some existing laws from them, and he himself has no ability, let alone teaching anyone.

Looking at Master Jesse's confused appearance, Zhang Yuan smiled and continued: "If you have an apprentice, if you encounter a problem similar to the one just now, you can arrange for the apprentice to study, if there are more apprentices, you can divide them into several groups to study different problems separately, and you are responsible for the research in the main direction while gathering and sorting out the research results of each group, isn't that good?" ”

"Smack!" Hearing Zhang Yuan's words, Master Jesse slapped his thigh and said, "Ah! Why didn't I think of that? Oh, yes...... Wouldn't it be much more convenient to find a few more helpers to study together? ”

In the excitement of speaking, Master Jesse suddenly remembered something, and said with a wry smile; "You see, I'm such a bad old man, and I'm studying inexplicable things, who is willing to learn from me, smiled and shook his head, Zhang Yuan said: "You don't need to worry about this, we don't look for adults, just find some children to bring to you, if you are interested, you can let Sister Wang take you to choose, in this way, you can cultivate from an early age, instill in them various ideas, let them become professional researchers, assist you in research, and inherit your career, isn't it great?" ”
