As mentioned above, Wang Yu finally found a method for modifying his memory, that is, the Reversal of the Qiankun Technique, but this method is not only highly demanding for cultivation, but even if it is refined to the extreme, it will take a long time to modify a person's memory.

Obviously, Wang Yu was not satisfied with such a technique, especially the long time required to revise a person's memory was unbearable for him. So, without hesitation, he began to read the other jade cylinders again, trying to find other spells that were more suitable for the current needs to modify the memory.

As Wang Yu continued to read and study, he gradually discovered that in fact, many spells were recorded in the spells to modify the memory, especially in each of the more than a dozen divine cultivation techniques on the fifth layer, but he also found that in order to implement these spells, the minimum requirements must be to reach the cultivation of the God King, and the time required is longer than the reversal of the Qiankun Technique. This made Wang Yu depressed. It's like when you're penniless, but there is a mountain of gold in front of you, and you can only look at it and can't use it, it will definitely make your mood crazy, and Wang Yu's mood is like this now!

The final search results were extremely disappointing to Wang Yu, until he had explored all the spells in the five layers, and he had not found a single spell that satisfied him. As a last resort, Wang Yu had no choice but to pick up the jade cylinder that recorded the reversal of the Qiankun Recipe again, and then began to study the spell of modifying the memory again.

"It takes 10,000 years for a god king to modify the memory of an ordinary god, so he is equivalent to the cultivation of a golden immortal, and he has cultivated a divine thought that only a god venerable can have, and at this time, the divine thought is relatively powerful. Now it's just a matter of modifying the memories of some low-level cultivators, and I wonder if it will take less time? Anyway, there is only one way to modify the memories now, so let's try it first. In case it takes too long, I have to pick a few disciples with the best qualifications to modify their memories, and the others just need to erase their relevant memories. After thinking about it, Wang Yu made up his mind.

After making a decision, Wang Yu once again studied the method of reversing the Qiankun recipe on modifying his memory, and after confirming that it was correct, he flashed out of the Qiankun ring.

"What's the matter?, is there a way?" Seeing Wang Yu appear again, Wang Mingxuan asked a little nervously.

"It should work, but you'll have to try to find out. Wang Yu replied with a smile.

"Is it to erase the memory, or to modify the memory?" Cao Feirong hurriedly asked. Looking at his watch, Xiàn seems to be very interested in such a method.

Cao Feirong seems to have an unimaginable enthusiasm for cultivation and strength, and he is also extremely enthusiastic about various cultivation techniques and spells. In the years of entering the cultivation realm. He didn't know how many exercises and spells related to cultivation he had learned from other cultivators, but he found that compared to the various exercises and spells that Wang Yu had learned from others, they were extremely crude and powerful.

So at this time, when he heard that Wang Yu had a way to erase other people's memories or modify other people's memories, his eyes immediately lit up, and his heart was moved. He knew that Wang Yu's transmission of the Fa must be a supreme masterpiece. Moreover, if you can master both spells. The significance is extraordinary. Imagine if you master this trick. Later, you can capture the disciples of the rival sect to modify their memories. Make them their own disciples, and then drive these people to deal with this sect, so that their enemies will not feel a great headache, and they will also save a lot of time in cultivating disciples. Of course. Cao Feirong also knew that the exercise of modifying other people's memories was extraordinary, and it was definitely not something that he could implement now, and even if he could implement it, he would pay a corresponding price, so he didn't have much hope for modifying other people's memories.

In addition, Cao Feirong also realized that even if he mastered the method of modifying his memory, he should not use it lightly, otherwise he would be hated by all the monks in the world, and even lead to annihilation.

"There are both, the spell to erase other people's memories shouldn't be a big problem, whether the magic trick to modify other people's memories can be successfully cast can only be known after trying it!" Wang Yu replied with a smile on his face.

As soon as he finished speaking, Wang Yu waved his hand to capture the Kunlun sect disciple who was closest to him and cultivated in the late stage of Jindan, and then immediately rushed back to his home in Shanghai, entered the Five Elements Time Array and began to try to modify his memory.

Two days later, Wang Yu walked out of the formation with a tired expression. Also walking out at the same time as him was the disciple of the Kunlun Sect. At this time, the Kunlun Sect's disciple's eyes looked at Wang Yu, no longer hatred, but full of respect from the heart.

Clearly, Wang Yu has succeeded. It took him two days to successfully modify all the previous memories of a Jindan late stage cultivator, and if this time was converted into the time in the formation, Wang Yu would have taken exactly one hundred and twenty days.

It took half a year to be able to modify all the memories of a cultivator in the late stage of Jindan, which greatly surprised Wang Yu. Wang Yu didn't expect his move to be so smooth, and the time it took him was countless times shorter than he expected. Wang Yu was very happy with this result.

Now that I think about it, this result should be closely related to the fact that I have such a powerful consciousness as a divine thought.

In the process of revising his memory, Wang Yu found that the most difficult part of the process was to suppress the resistance from the original soul, and the moment his divine thoughts surrounded the opponent's soul, this resistance disappeared completely, and even the other party's soul took the initiative to cooperate with himself to transform every trace of memory. Therefore, what seemed to others to be a difficult link was completed effortlessly under the influence of Wang Yu's divine thoughts. This laid a solid foundation for him to complete the rest of the work.

Wang Yu guessed that it might be because his divine thought level was too high, which made the other party's soul unable to resist. With this, Wang Yu further deduced that if the memory of immortals or gods was modified in the future, it might also have this effect, but the effect would never be so ideal. After all, whether it was an immortal or a god, their souls were many times stronger than those of the cultivators of the Jindan period, and the deterrent effect of their own divine thoughts on their souls would definitely be much smaller.

In addition to the above-mentioned difficulties, in the process of modifying the memories of others, there is also a difficult part of carving memories in the soul. You must know that the soul is a relatively fragile being, and now it is not difficult to imagine the difficulty of portraying memories on the soul of the other party without hurting it in the slightest. This requires the caster to have an extremely subtle level of control over his or her own divine consciousness (or divine thoughts). It is extremely difficult to achieve this kind of process without cultivating the relevant techniques, without practicing for a long time, and without firm perseverance.

However, for Wang Yu, it is precisely such an ability. Whether it was the continuous mobilization of divine thoughts to save the lives of 153 million compatriots before, or the continuous deduction of formations with divine thoughts before dealing with the Eight Miscellaneous Great Snakes, they spent a lot of time on the control of divine thoughts (it took about 2,000 years before and after), and after such a long period of practice, it can be said that at this time, Wang Yu's control of his divine thoughts completely met or exceeded the requirements of carving memories in the soul.

It is precisely because of the above factors that what is extremely difficult for others to accomplish is relatively easy for Wang Yu. Therefore, not only does it take him much less time to modify a person's memory than that of a god king, but the success rate will definitely be much higher.

However, Wang Yu still overestimated his own strength, and the time it consumed to modify a person's memory was not only directly related to the difference in strength between the caster and the soul of the modified, but also had a great relationship with the amount of memory in the soul of the modified.

A cultivator in the late stage of Jindan, his cultivation time is only a short period of a few decades to hundreds of years, and the memory in his soul is insignificant compared to a high-level cultivator who can easily take hundreds or thousands of years, and with the improvement of the cultivation of the modified person, the stronger the soul of these people will be, and the stronger the power of their resistance, so the time taken to modify the memory of these people will inevitably increase exponentially.
