After temporarily persuading Ji Yao, Zhang Yuan retired first, after all, he should still be very busy at the moment, so even if he personally led him to the forward battalion, it would have to be a day or two later, as for now, it is best to be able to implement the billion funds on himself first, so that his strength can also be further increased.

When he left from the place where Ji Yao lived, Zhang Yuan still looked very hurried, but when he came to a place where Ji Yao could no longer check, Zhang Yuan slowed down his pace, and then turned towards the Sect Master's Mansion, after all, it was also there, so that he could really improve his strength with confidence, even if Tang Fei, who had been guarding there at the moment, was not so reassuring, but compared to other places, Zhang Yuan felt that it was better there.

After returning to the Sect Master's Mansion, Zhang Yuan casually looked for a more hidden room, and then opened the system in his body again, there is no doubt that this time, Zhang Yuan still chose the cultivation items, and then searched carefully in them, just like the exercises that he chose last time that can stimulate his potential, Zhang Yuan will not choose those ordinary exercises this time, after all, such exercises are really not very helpful for enhancing his strength, and the other point is that although the billions of funds sound a lot, compared to the exercises that need to be exchanged at the moment, these billions of funds are really not a lot。

Of course, in order to be able to make his billions of funds serve him more, so when Zhang Yuan chooses, he still starts with those exercises that need the lowest exchange value, but unfortunately, these exercises that need low exchange value really don't have any exercises that can greatly improve his strength, and most of these exercises are also some eight brocades, Shaolin Changquan and other exercises, and after exchanging these exercises, although you can master them immediately, you can't let yourself understand them, and if you want to really exert some strength, you still need to practice for a long time.

When the exchange value reaches tens of millions, it is some exercises involving internal strength, and as long as these exercises are exchanged, although they can not let themselves master the exercises until they are achieved, they will also produce a part of the internal force in Zhang Yuan's body, so in this way, Zhang Yuan's strength can be directly improved by a part, and there are many such exercises, if Zhang Yuan can exchange as much as possible, it is impossible to say that the sum of the internal force improved by each exercise can also be improved rapidly。

Of course, after all, each of these exercises requires tens of millions of exchange values, which represents tens of millions of funds, and his own billion funds can only be exchanged for a limited number of exercises, so Zhang Yuan must find some exercises that can make him qualitatively ascend among these exercises, so that he will not let himself waste these funds in vain.

To tell the truth, these tens of millions of exercises with exchange value are actually not the most expensive exercises with exchange value in the lower level, on top of these, there are more than a dozen exercises that require hundreds of millions of exchange values, but these exercises are different from those martial arts exercises before, but they already belong to the category of exercises of cultivation, the reason why Zhang Yuan did not consider exchanging these kinds of exercises is entirely because these dozen exercises are completely general exercises in the source world, and these exercises will not have much development, so Zhang Yuan directly gave up these exercises, after all, if he wants to practice these exercises, he can learn them directlyThere is no need to waste the funds that have come so hard.

Zhang Yuan chose a long time among these exercises, and finally selected a few exercises that Zhang Yuan thought were good, and then began to exchange, just like the first exchange of exercises, when these exercises were directly exchanged, the practice methods of the exercises directly entered his mind, and at the same time, some internal forces generated from nowhere entered his body, and directly followed some kind of road map, running in Zhang Yuan's meridians, not only that, but those newly generated internal forces, as if they were in a different time and space from the true element in their own body, did not have any reaction with the true element at all, even if there is a true element in the original meridians, the internal force seems to be running in the empty meridians.

This situation made Zhang Yuan a little surprised, it was because he was afraid that the exercise that had just appeared would conflict with the true element in his body, so the first exercise that Zhang Yuan exchanged was a very gentle internal force, and the reason why this was so was because the internal force and the true element underwent unknown changes in the body, but although he didn't understand why this happened, it also made Zhang Yuan feel a lot more relieved.

Since he knew that there would be no conflict between the internal force and the true element, Zhang Yuan no longer hesitated, and then began to exchange it again, and the several exercises selected before were exchanged by Zhang Yuan into his body in a very short period of time, but when Zhang Yuan exchanged all these exercises, he found that the exchange of exercises seemed to be a little different from what he imagined.

At the beginning, Zhang Yuan originally wanted to prepare to exchange as many exercises as possible, so that these initial exercises could gradually converge, so that he could successfully fill up the internal force in his body in the shortest possible time, but now these internal forces are exactly the same as the way he got along with Zhenyuan before, and they also do not affect each other, as if each internal force exists in an independent meridian, no matter whether these internal forces will meet in the meridians, they will not merge or exclude each other, and they don't seem to feel each other at all。

Faced with such a situation, Zhang Yuan really didn't know how to explain it, although Pangu had said before that before he successfully promoted to the Golden Immortal Realm, the other party would not give him any help, but Zhang Yuan also understood that if it was about this system, Pangu would presumably want to understand it more than himself.

"Brother Pangu, can you see what's going on now?"

Things were really as Zhang Yuan guessed, Zhang Yuan had called Pangu who had no response several times before, and this time he finally gave his own response, but the answer made Zhang Yuan himself a little surprised, because the moment Zhang Yuan's inquiry fell, Pangu immediately replied: "What do you want to ask? First of all, you need to tell me what happened?"

After hearing Pangu ask this, Zhang Yuan once again kept silent about the situation in his body, because just Pangu's question was enough to make Zhang Yuan understand that the situation in his body at the moment, Pangu didn't notice it at all, Zhang Yuan believed that if Pangu really saw the situation of these internal forces in his body, he should be able to clearly know what he was asking, but at this moment, Pangu suddenly said such words, which is enough to prove that these new internal forces in his body, he can't see it at all.

Since the operation of these internal forces, Pangu can't see it at all, Zhang Yuan feels that there seems to be no need to tell him these things again, he thought that what happened in his body would be perceived by Pangu, and if he wanted to conceal Pangu to enhance his strength, he could only use the knowledge that directly entered his mind to improve himself, but at this moment, Zhang Yuan suddenly realized that it seemed that the things that this system had improved were completely outside Pangu's perception, so that he didn't have more hole cards.

Of course, at this time, Zhang Yuan also had a rough guess about the situation in his body, his body has not actually undergone any changes, and the true element in his body is still running normally, but the things carried by this system have nothing to do with his body at all, although he doesn't know who the maker of this system is, but at this moment, it seems that the other party thought at the beginning that there are many internal forces or true elements that are completely mutually restrictive, and such internal forces or true elements are absolutely impossible to coexist peacefully, so the creator of the system thought of another method。

The method that the system creator thought of is actually very simple, that is, the exercises obtained in these systems will not appear in their own body, but in a body in their own consciousness, and each exercise will exist in an independent consciousness body, and if you want to use the internal force or true element in these consciousness bodies, you only need your own consciousness as a traction, to put it bluntly, these internal forces or true elements just exist in a different dimensional space, and the reason why this different dimensional space can even be concealed by PanguIt is entirely because this kind of interdimensional space is a combination of the virtual and the real, because it is a spiritual extradimensional space.

In fact, about this kind of cultivation method, some people have proposed it in the source realm, but if you practice like this, although you can hide your strength in front of others, but in the same way, it also requires more waste of time for cultivators, after all, in the same time, other cultivators can practice to two points of true yuan, but if you use this cultivation method to practice, you can only get two parts of the true element, and these two parts of the true yuan cannot be fused, so it will be much slower than other people's cultivation speed, so no one will choose this kind of cultivation method。

Zhang Yuan also thought of this possibility after seeing that Pangu could not detect any changes in his body, otherwise, Zhang Yuan would never have thought of this matter, and the reason why he didn't find it when he exchanged the exercises for the first time was just because the first exercise was just a running route of the exercises, and did not produce any internal force, so Zhang Yuan only found out about this matter this time.
