Wang Yu saw that he couldn't destroy the Tower of Babel, and all the Kunlun sect disciples in the Kunlun Secret Realm had been imprisoned by himself, and at this time, he had nothing to do to stay in the Kunlun Secret Realm, and there were still many things waiting for him to deal with in the outside world.

So, Wang Yu began to play a series of tricks at the exit of the space, and as before, the moment the tricks were completed, a spatial passage immediately appeared in the void, and seeing that the spatial passage had been formed, Wang Yu stepped in. The next moment, Wang Yu appeared in the back valley of the Kunlun Palace.

At this time, when Wang Yu looked at the relatives again, he found that they were all still busy, and most of them were busy concentrating the remaining low-level disciples of the Kunlun Sect. And what are brother-in-law Cao Feirong and father Wang Mingxuan discussing?

So, Wang Yu moved to their side one by one. Cao Feirong and Wang Mingxuan were both accustomed to Wang Yu's sudden appearance, so they didn't express too much surprise.

Seeing Wang Yu coming to his side, Wang Mingxuan couldn't wait to pull his son over and asked, "Yu'er, what do you think of the remaining low-level disciples of the Kunlun Sect to deal with?" After all, they are all innocent, and we don't have any direct hatred for us, and we have already killed enough people today, I think it would hurt God and God to kill them again!"

Seeing that his father finished speaking, Cao Feirong hurriedly said: "It's okay not to kill them! But the premise is that if we can erase their memories today or modify their memories! Otherwise, we must not leave more than a thousand enemies!"

Seeing Cao Feirong's determined expression, Wang Yu could be sure that he had the determination to cut the grass and eradicate the roots.

Wang Yu felt that what his father and brother-in-law said made sense. However, Wang Yu also realized that his family had killed enough people today. And killing too many people will definitely do more harm than good to the current family, not to mention killing these people who have no power to fight back, so Wang Yu wants to let them go. However, as my brother-in-law said, I will never allow them to become my enemies. Therefore, there is only one way left for Wang Yu now, and that is to find a way to erase their memories today, or modify their memories.

"Erasing their memories or modifying their memories? Wang Yu groaned.

Wang Yu does have a way to erase the memories of others, and there are detailed records and explanations in the soul cultivation formula. But Wang Yu thought about it, just erasing their memories. It's really a pity, because the remaining more than 1,000 Kunlun sect disciples are all rare cultivators, especially the two hundred and thirty-two people in the Kunlun Secret Realm. So it's a shame to just erase today's memories and discard them. Thinking of this, Wang Yu decided to try to find a recipe to change his memory.

So, after Wang Yu gave a rough explanation to his father and brother-in-law. He began to search for the memories of Dragon Ancestor Ao Tian in his brain. However. What disappointed Wang Yu was. After searching for a whole day, he almost left Long Zu in his brain, searched all the exercises, and did not find the spell he wanted. However, Wang Yu was not discouraged, but continued to search. Not only did he search all the exercises that Dragon Ancestor Ao Tian had left in his brain, but he also didn't let go of the exercises that Pangu had fused into his brain, but the result was still a big disappointment to him.

As a last resort, after a little muttering, Wang Yu decided to enter the Tibetan scripture hall of the Qiankun Ring to find the relevant magic jade cylinder. So after Wang Yu had a thought, he came to the Qiankun Ring.

When Wang Yu entered the Qiankun Ring, the Qiankun Ring immediately turned into a tiny speck of dust floating in the air. Since the Qiankun Ring is a space holy weapon refined by Pangu himself, it can be said that it is another small universe opened up by Pangu, and the entire space is full of chaotic aura. Therefore, the dust that was transformed by such a holy weapon was almost identical to other dust in the air, and it was impossible to distinguish it from the spiritual consciousness of a cultivator, the immortal consciousness of an immortal, or the divine consciousness of a god. Even if the divine mind of the deity is not specially searched, it is difficult to find its existence. Moreover, as a holy weapon, its defensive power is also unparalleled, and the holy weapon cannot be broken unless it is a holy weapon! Although the Qiankun Ring is an acquired holy weapon refined by Pangu, due to the integration of a large amount of Hongmeng Aura and Xuanhuang Qi in the refining, therefore, although its quality is acquired, it is better than the congenital, and its defensive power is definitely better than that of the innate holy weapon, even the innate holy weapon Donghuang Zhong, which is famous for its strong defensive power, is slightly inferior to it. It can be seen from this that it seems that having the Qiankun ring Wang Yu is equivalent to having a turtle shell that will never break, and everything will be fine as long as he drills into it in case of danger.

However, in fact, it is far from that simple, first of all, the defensive power of the holy weapon is directly proportional to the user's cultivation, and a god can break the holy weapon used by an ordinary god using a royal artifact. Therefore, having a holy weapon does not necessarily ensure that one's own safety is foolproof. Secondly, Wang Yu can't use the Qiankun Ring as he wants, especially his own entry and exit of the Qiankun Ring. Wang Yu found that when the Qiankun ring is used as a general storage ring, it will not show any abnormalities, but once he enters and exits the Qiankun ring, a trace of the unique breath of the holy weapon will be leaked at the moment of entering and exiting, although this breath is very weak, so weak that it is almost imperceptible, but Wang Yu can be sure that the god who has the divine thought, and even the master of the later stage of the god king will be able to detect this breath in the case of close observation, and then he will be able to find the existence of the Qiankun ring, Wang Yu believes that once the Qiankun ring is discovered by the god or the god king, then not only the Qiankun ring is not guaranteed, but also his own life may be finished, and even affect relatives。 Therefore, in fact, Wang Yu will never enter and exit the Qiankun Ring at will unless it is absolutely necessary. However, it is still on Earth, and this concern should be dispelled. Therefore, Wang Yu only entered the Qiankun Ring after a slight hesitation.

After Wang Yu entered the Qiankun Ring, he went straight to the Tibetan Scripture Hall. When he arrived at the Tibetan Scripture Hall, he went directly to the cabinet, picked up the jade cylinders placed in the fourth layer from the cabinet and began to read them one by one.

The reason why Wang Yu didn't start reading from the first layer, but started directly from the fourth layer, is mainly because the first layer is some immortal cultivation exercises, these exercises are relatively upright and peaceful, and there are very few more evil cultivation methods such as modifying memory, and the fourth layer mainly places some relatively rare special techniques. Therefore, it is more likely that the modification of memory recipes will appear in the fourth layer.

Sure enough, it was not unexpected, and soon after, he found a strange technique called the Reversal of the Qiankun Jue from this layer, which was extremely cultivated to the point that it could reverse the Qiankun and reverse yin and yang, including memory, which could be modified at will. Wang Yu couldn't help but be overjoyed to see that he had gained such a harvest in such a short period of time.

However, after Wang Yu's careful study, he found that this recipe has great drawbacks.

First of all, it is extremely difficult to cultivate this technique, and without extraordinary talent and opportunity, without great effort and long-term cultivation, it is simply impossible to achieve it, and there is no time to do it now.

Secondly, this recipe is definitely an evil exercise, and there are many conflicts with the Pangu recipe that I am currently cultivating, so it is not suitable for my own cultivation.

Thirdly, in order to use the modified memory spells described in this recipe, the minimum requirement is that the person who casts it must have the cultivation of the god king, because only those who have cultivated above the god king have the powerful divine consciousness required to meet the process of modifying their memory.

Fourthly, although a person who has cultivated to a god-king or higher level can cast the memory modification spells recorded on the recipe even if he does not practice the formula, it requires that the mental cultivation (i.e., soul realm) of the target must be at least five levels lower than that of the person who performs the formula.

The fifth point, which is also the most unbearable point for Wang Yu, is that if this trick is not refined to the extreme, the time required to modify a person's memory can definitely be described as "long". According to the formula, if the recipe is not cultivated to an extremely high level, even if the god king wants to use this spell to modify the memory of an ordinary god, it will take tens of thousands of years, and it is extremely easy to make mistakes, and the result of the mistake will completely lose the memory of the object being cast, and become a walking corpse. Therefore, in the final remarks, this recipe is specially emphasized that it should be used with caution when this recipe has not been cultivated to an extremely high level. (To be continued......)
