The first of those three places was on an unknown island called Blackreef Island, thousands of miles into the endless sea to the south, which belonged to the buffer zone set up by the armistice between the human monks and the Sea Tribes in the southern part of the continent, and was closer to the Sea Tribe's border line, which was extremely dangerous.

Although it is now a truce, the grudge between the Sea Clan and the human monks over hundreds of thousands of years and hundreds of wars cannot be bound and eliminated by a single armistice letter, and it is unlikely that a large-scale invasion will occur in the buffer zone, but the endless vendetta and fighting between the two clans has been staged in the buffer zone.

The buffer zone where Blackreef Island is located is an incomparably chaotic area, which contains countless Crouching Tigers, Hidden Dragons of the human and sea tribes, and there are many dangers, but it is indeed an excellent camouflage hiding place, in the buffer zone that the sect forces of the Spirit Sword Mountain cannot reach, Kou Zhenying can be at ease, and the safety is greatly guaranteed, so Kou Zhenying is very likely to attack the Yudan in the cave on the Blackreef Island located in the buffer zone, and then fail and fall.

But the buffer zone is mixed with dragons and snakes, if Kou Zhenying really succeeds in attacking the Jiedan, it will definitely cause the vision of heaven and earth, and then attract the spied eyes and murder of the small people, Kou Zhenying is not an unwise person, unless he has the treasure secret method that can cover up his success in causing the vision of heaven and earth, otherwise the extremely cautious and cunning Kou Zhenying will never be in the cave of Blackreef Island.

The cave mansion on Black Reef Island is the least likely of the three selected by Yin Ning, and the one with a slightly higher probability is unexpected, it is actually in the part of Zhaojiang controlled by the Corpse Nightmare Sect, but Yin Ning thought about it for a while, and he also understood Kou Zhenying's good intentions in this choice.

As the leader of the two sects of the Zhaoyou Kingdom, although the Spirit Sword Mountain and the Corpse Nightmare Sect are not in a state of war, they are definitely hostile relations with the intention of destroying each other, and the two sides are constantly making small and medium-sized moves in secret, sending spies to each other to infiltrate the other sect to detect and explore the secrets, and even do some sabotage, do some tricks, and let the other party's treasure refining weapon alchemy and other achievements fail, which is even more common.

In short, knowing that there will be a battle between the two sides in the future, the Corpse Sect and the Spirit Sword Mountain are trying their best to block each other, and there is no doubt that Kou Zhenying, a master disciple carefully cultivated by the original Spirit Sword Mountain, and the current traitorous and self-reliant person, will provide some shelter, so that the other party can stay in their sphere of influence temporarily, the Corpse Nightmare Sect is completely happy, after all, as long as Kou Zhenying survives for one day, he will always be the shame of his mortal enemy Spirit Sword Mountain, and the unreasonable outsiders only know that even the demon slaying sword Kou Zhenying, who ranks fourth in the twenty-four swords of Zhenyi, will break away from and defect to Spirit Sword Mountain, then it can be predicted that the weakening of Spirit Sword Mountain will greatly damage the prestige of Spirit Sword Mountain。

And Kou Zhenying himself, hiding within the sphere of influence of the Corpse Nightmare Sect, the sworn enemy of his original sect, is also quite at ease, especially in Lingjian Mountain, because he was afraid that the "Daze Sword Sutra" would be made public, so when he announced the reason for wanting Kou Zhenying, a traitor, he was brutal by nature and accused of killing his fellow disciples.

This made Kou Zhenying, who didn't have to worry about the Corpse Nightmare Sect and coveted himself who had the "Daze Sword Sutra", and even more peacefully hid in the territory of the Corpse Nightmare Sect, a sworn enemy that was inconvenient for Sword Mountain Sword Cultivators to enter on a large scale.

The jade slips in the night storage bag have no record of the cave mansion built by Kou Zhenying in the part of Zhaojiang under the control of the Corpse Nightmare Sect, and Yin Ning has no way of knowing from the description of those three words whether it is secret and safe, whether it is full of spiritual energy, whether it is inaccessible, and it is suitable as an ideal place to attack the Dan period.

But Yin Ning thought to himself that if he was Kou Zhenying at the beginning, when his life was approaching, he would desperately go to the Yudan period, and in the face of his more than 20 cave mansions, he would definitely include this cave mansion in Zhaojiang as an alternative.

The last cave is the place where Yin Ning's opinion is most likely to leave the body of the fallen Kou Zhenying and his burial goods "Daze Sword Sutra", because the location of the cave is actually in the great wilderness land in the north, which is full of fierce witch and barbarian tribes, dangerous and abnormal, but the great wilderness is vast, fierce beasts are rampant, there are many dangerous places, and there are often no traces within thousands of miles, as long as you avoid the migration routes of those witch barbarian tribes, and choose to find a secret and safe place as an impact on the cave mansion of the Jiedan period, it is very easy.

The so-called witch barbarian tribe is not another race, they are also human beings, they are a branch of human beings, and they also have cultivators among them, but they are not like most human cultivators in this realm who use the cultivation of true exercises and body refining exercises to cultivate spiritual power, but practice the ancient martial arts of cultivation from the barbarian period.

Yin Ning is in this human world, because at the end of the flood period, suffered from the cross-border invasion of the demons, the human monks of the spirit world and even the immortals of the fairy world once came to the aid of the lower realm, and the human beings gradually gave up those witch barbarian cultivation methods that were difficult to cultivate and succeed in the battle side by side with the spirit monks and immortals, and changed to the art of cultivating the truth.

After a long and arduous struggle between the human monks and the spiritual monks and immortals, they finally defeated the invading demons, drove out all the demons, completely closed the spatial passage of the demons invading this world, and completely defeated the demons, most of the human monks have almost all changed the cultivation techniques passed on by the spiritual monks and immortals.

The reason why the human cultivators in this realm so simply abandoned the witch barbarian cultivation technique created by their ancestors was not because they really wanted to forget the scriptures, but because the witch barbarian cultivation technique was too difficult to cultivate, and it was too difficult to cultivate successfully, and the qualification requirements for cultivators were too high.

How high is the qualification of cultivating the art of witchcraft for cultivators? If we compare it with the qualifications of the spiritual root level of the current cultivation realm, only human cultivators who have reached the qualification of the spiritual root level of the upper grade of the Xuan level have the minimum cultivation qualifications, which almost blocks most of the human cultivators from cultivating the art of witchcraft and barbarianism.

As far as Yin Ning knew, the total number of people of the witch barbarian tribe in the legendary northern wilderness land was no less than the total number of human beings in the southern part of the entire continent, but the number of wizard barbarians who cultivated the art of witch barbarians possessed by those witch barbarian tribes was only one-fiftieth or sixty-tenth of that of the cultivators in the southern part of the continent.

The harsh cultivation conditions are the main reason why the cultivation technique of witches and barbarians has been abandoned by most human beings, but at the end of the flood and famine tens of millions of years ago, in the great divergence of the human race after resisting the successful invasion of the demon race, most of the human beings began to advocate the cultivation method of human cultivators and immortals in the spirit world, but there are also a small number of stubborn human beings who still insist on cultivating the cultivation techniques passed down by their ancestors.

Soon the two groups of human cultivators who parted ways began to have disputes, and even wars broke out, and in the end, without accident, a small number of witch and barbarian cultivators were defeated and driven into the dangerous and desolate wilderness, and were called the witch barbarian tribe by the world.
