With the passage of time, many people have forgotten the glory of the Taishang Induction Gate, Luo Xiu also knew these from the memory of the old man, after there was no gain from the elixir, Luo Xiu did not give up and went to the library building, the entire library building is hundreds of meters high, and what is even more terrifying is that the inside of the library building is actually a space spirit treasure with an extremely huge space, so Luo Xiu is actually a little unsafe in it.

Although he knew that this thing had no ability to kill enemies at all, but the ability to trap people was unimaginably terrifying, as soon as he entered here, Luo Xiu felt that his body had been scanned more than ten times, if it weren't for the fact that he had disguised everything from the inside out, including the soul breath that he had disguised with the help of the system's ability, he had already been exposed at this moment, even so, being here, he still felt a burst of fear.

Luo Xiu didn't stay in other places, he went straight to the area where the soul class secret method was located, he had to solve the problem on his soul as soon as possible, there was no way, if he really delayed it like this, there would definitely be problems with his soul body, so he himself would be very unsafe.

In particular, the most crucial point is that he is now in such a strange world, and many things that seem extremely small to him will probably expose his true identity, so that he does not dare to be careless at all now, every moment, when doing anything, he must mention 120,000 points of concentration, even if he retreats, he cannot wholeheartedly enter the state of deep cultivation.

After reading all the exercises that could be retrieved around him, and at the same time letting the system record them, Luo Xiu flipped through other areas and recorded all the exercises that could be recorded, as long as they didn't take the exercises out, the caretaker of the library didn't care at all.

After all, the Taishang Induction Gate, the included exercises, are almost all some big road goods, and the top exercises are not accessible to ordinary people at all, so this group of guys doesn't care about the leakage of these exercises at all, and they don't think that Luo Xiu will practice these exercises, so for the older cultivators like Luo Xiu, who have worked hard and have high skills, the Taishang Induction Gate is still very generous.

It took more than ten days of hard work, Luo Xiu collected all the exercises that could be included, and screened the exercises that were useful to him with the help of the system's ability.

It's just that Luo Xiu was surprised inexplicably that in a pile of miscellaneous books, he actually found an exercise that was extremely suitable for his current situation, of course, the most important thing about this exercise is not how strong his ability is, but what this exercise records is the secret method of how to repair the damage on the body.

It's just that when Luo Xiu read the introduction of the whole book, he couldn't help but smile bitterly, this exercise is normal for others, but the only thing is that when cultivating this secret method, you must soak in the water of the Tongtian River to cultivate, which makes Luo Xiu helpless.

Because the river flowing in the Tongtian River is full of spiritual energy, ordinary monks do not dare to enter the river at all, and when they enter the Tongtian River, almost in a very short time, the physical body will be assimilated by the river, and the energy attributes in the body will also become the same existence as the Tongtian River, becoming a part of the Tongtian River.

This is also why the Tongtian River is such a strange existence, the water flowing in the entire Tongtian River, in fact, many of them are composed of monks' corpses, and the Tongtian River contains extremely terrifying aura, and almost none of these auraes can withstand the invasion of the aura of the Tongtian River.

Because of some special reasons, almost all the monks in this world who are close to the longevity will walk into the Tongtian River alone and turn themselves into a part of the Tongtian River, so unless there are some guys who want to die, no one will take the initiative to enter the Tongtian River, and the water connected to the Tianhe River is not something that ordinary monks can bear.

Looking at the exercise provided by the system called the Heavenly God Nine Transformation Refining Body Decision, Luo Xiu was actually a little blinded, and it was not difficult to see from the name of this exercise that this was an exercise that had been passed down from the Yunding Heavenly Palace, but he didn't believe that the group of guys in the Yunding Heavenly Palace could withstand the erosion of the Tongtian River.

"System, I'll get some Tongtian River water later, you study it, see if there is any way to eliminate the corrosive power inside it, if it can be successful, then I will enter the Tongtian River and repair the damage on my body, there should be a chance, it depends on whether this Heavenly God Refining Body Technique has any effect!" After pondering for a long time, Luo Xiu finally made up his mind, he was going to get some Tongtian River water first, let the system study it, and see if there was any way to decompose the terrible erosive power contained in it.

"Okay, in fact, this system is also curious, such as the Tongtian River, which violates the laws of physics, how did it form, and why did it appear here, this Tongtian River simply broke the existence of those physical celestial bodies in the database of this system, no matter how the system calculates, it can't understand the scene in front of you, in this cosmic void, without any gravity or other external forces, this river can still flow like an ordinary river, it's incredible!" The system was very urgent, and said to Luo Xiu.

There is no way, any person from the Earth Federation will be destroyed by this heavenly river, at this moment, Luo Xiu is standing in the courtyard, he is inside the planet, looking up at the sky, at this moment, the river above their heads is flowing above their heads, such a strange scene, it is simply eye-catching, with Luo Xiu's experience of traveling to many planes, I can't believe that I will see such an unconventional cosmic landscape one day.

In his opinion, this almost anti-scientific existence simply broke his three views, making Luo Xiu still feel so inexplicable and wonderful every time he sees this scene. If it weren't for Luo Xiu's discovery before, he wouldn't dare to imagine that he would see such a scene one day and become so calm.

Especially the experience during this period of time, he was deeply aware of the special meaning represented in this plane he was in, no matter where he looked at it, it was hard for him to believe that he could still remain calm, but he really did it, and it was very unexpected for him.

Of course, Luo Xiu didn't dare to go to the Tongtian River to steal the water of the Tongtian River in a bright light, not to mention whether he could do it or not, just the extremely dense terrifying spiritual pressure around the Tongtian River was not something he could bear now, of course, referring to his current identity.

If his body goes, there will be absolutely no problem, even if he takes a bath in the Tongtian River, it will just be a waste of time, but he can't really go there, so if he wants to study the secret of the Tongtian River, as well as the powerful corrosive power in the river, Luo Xiu must find a way to get this thing, fortunately, in the Taishang Induction Gate, there is such a thing as Tongtian River Water for sale, although the asking price is very high, but it can indeed be said to be the circulating currency of this world.

It is somewhat inappropriate to say that the water of the Tongtian River is a circulating currency, it should be that the water of the Tongtian River has been packed in a special bottle to form a transaction currency, these are not very common things, in the entire area of influence where the Taishang Induction Gate is located, there is no spirit stone or the like that contains spiritual energy, it is calculated by the number of Tongtian River water, and it also has a great relationship with the cultivation methods of the Taishang Induction Gate and the Genting Heavenly Palace.

Coming to the Good Gong Hall, Luo Xiu exchanged a few bottles of Tongtian River water, and hurried back to his residence, along the way, he was carefully using his divine soul power to check these Tongtian River water little by little, and sure enough, he found nothing, he found nothing from these rivers, except for feeling its rich heaven and earth aura, which made Luo Xiu frown slightly, he knew very well that the things contained in the water of Tongtian River were definitely more than that, otherwise, it would be impossible to explain the terrifying and corrosive power it had.

It's just that his own knowledge is limited, and he can only hope that the system in his mind can see what is wrong, after all, he has not seen the spiritual water containing the spiritual energy of heaven and earth, and he has also drunk a lot of spiritual water of heaven and earth, but similar to Tongtian River, it is almost abnormal spiritual water in his opinion, and it will have such a terrifying corrosive power, which is beyond Luo Xiu's imagination.

Returning to his residence, Luo Xiu took out the river water as soon as possible, and also took out various testing instruments, with the assistance of the system, he easily tested all the inside and outside of the river, Luo Xiu shook his head speechlessly, and found nothing, except for the ordinary water mixed with a powerful aura, the combination of the two to form this river water, there was no other discovery.

To say not surprised, it is impossible, although he had some guesses in his heart before, but when he found nothing, he was still very disappointed, and at the same time, Luo Xiu couldn't help but have some guesses in his heart, this situation in the Tongtian River is very abnormal, obviously, this is what he has ignored, or the direction of his research itself is wrong, thinking of his previous thoughts, and what he is doing now, Luo Xiu couldn't help but pat his forehead speechlessly, showing a wry smile.

"System, I think there is something wrong with our research direction, since it is the water in the Tongtian River, which has a strong corrosive force, then we study this little thing, there is no reference value at all, and even I doubt that after these rivers leave the Tongtian River, there will be some changes that we don't know, such as that special power, will disappear completely because of the scarcity of the river! Or maybe these rivers we bought have been processed by others, but the thought of sneaking out at this opportunity to get some original Tongtian River water is really a bit difficult, although it seems that this Tongtian River is not guarded at all, but from the memory of this old man, I know that where these Tongtian rivers pass, there are powerful formations guarding them, is there any way to get the water of the Tongtian River quietly?" After a long time without results, Luo Xiu had to turn to the system in his mind, and at the same time tell his guess, after all, there is only such an explanation, which can be explained, and now he has nothing to learn from these rivers, and all he can think of is this.

Thinking of his previous impulsive thoughts, Luo Xiu at this moment couldn't help but feel helpless, for him, this situation was definitely not what he wanted to see, even if his whole person was imprisoned in this world now, he didn't want to take risks, although it was impossible to expose it with his current behavior, but in order to prevent uncontrollable accidents, he had to think about everything clearly, and all dangers had to be thought through.

"Your speculation, in fact, there is a little truth, but I am more inclined to the Tongtian River itself has a problem, the river water may be a very ordinary water containing spiritual power, but the entire Tongtian River itself may be a whole, and the river water circulating inside it has been contaminated with a special substance on the riverbed of the Tongtian River for a long time, so that the water of the Tongtian River has some special magical powers! The most important thing is that the Tongtian River we see is just the downstream of the Tongtian River, have you noticed that the direction of the main body of this river circulating in the Void Universe is simply nothing, it is obviously flowing directly in the Void, in the Void Universe, what secrets are unknown, but this system is sure that there must be an extremely wide world inside, or this entire Tongtian River is actually flowing in the Endless Void Plane!" After listening to Luo Xiu's words, the system also fell into a deep groan, and then he asked with a hint of hesitation in his tone.

"I don't quite understand what you mean, is it possible that you mean that this river is actually a bridge between the positive and negative worlds, and it's not right, this rich heaven and earth vitality can't be faked, is there really something in this, we have to go to that river to see it in person, to be sure? It's just that I always feel that it doesn't seem to be as complicated as I think, just think about it, I think this river is a river with a powerful spiritual power, it is a special existence in itself, and the most important point is that I can be 80% sure that there must be something strange inside this Tongtian River, otherwise, it can't be explained that the throughput of the river channel that flows in the endless void is almost the same size, and if you look up, you can find the weirdness of this river, which shows that there are many things that we ignored before!" Looking up at the magnificent Tongtian River overhead, Luo Xiu had some guesses at this moment, and his tone was not so sure, so he said hesitantly.
