To the west, the dim sky gives people a different kind of depression, in the sea of no return, it seems that everywhere, no place can see the sun, this depression, so that both people and demons in the sea of no return have a kind of madness from the depths of the soul.

Shen Mu ran all the way to the west, relying on the excellent perception given by the Blue Bird Split Soul, there was not much trouble along the way, and occasionally there were a few people who relied on their own strength to overpower Shen Mu and then make a move, Shen Mu was easy to solve, his true strength could not be judged from the surface.

Until the sky completely darkened, and the sea of no return completely sank into the night, Shen Mu stopped, the sea of no return at night, almost out of sight, in the sea of no return, acting at night is a taboo.

Shen Mu found a cave, then took out the medicine he had prepared before, and sprinkled it at the entrance of the cave to drive away snakes, insects, rats and ants, this is something that Ji Tianxuan told him to bring with him, which can have a great effect.

Take out the torch in the storage bag, light it, hang it in the hole, Shen Mu took out the tortoise shell and storage bag obtained during the day, in addition to a few spirit stones and a demon crystal in the storage bag, there are also some black iron items, which should be used in the sea of non-return, and then there is nothing in the storage bag, this big man is also very poor, the only thing that can make Shen Mu interested is the black tortoise shell.

Holding the tortoise shell in his hand, Shen Mu's divine sense probed into it, but it was immediately bounced back, this tortoise shell was resisting his exploration, and the previous big man's consciousness on the tortoise shell only stayed on the surface, and it was easily erased by Shen Mu, which should be the main reason why he couldn't use the tortoise shell thoroughly.

Shen Mu did not give up, poured all his divine sense into the tortoise shell, and struggled to break through the self-protection of the tortoise shell, Shen Mu gritted his teeth, the resistance of the tortoise shell was very strong, but Shen Mu was not a person who gave up easily, it was precisely because of such a strong resistance of the tortoise shell that it was more precious.

Vaguely, Shen Mu seemed to hear a low roar, warning him not to probe his divine sense again, this feeling made Shen Mu seem familiar, when he was in the Wu Xixue Dark Pavilion, the tortoise shell forbidden made a similar roar.

Thinking of this, Shen Mu didn't hesitate, he directly bit his finger, dripped blood on the tortoise shell, and seeped into the tortoise shell with a little bit of light blue blood, and the resistance of the tortoise shell really melted down little by little!

Shen Mu was overjoyed in his heart, and his divine consciousness invaded the tortoise shell in a big way, imprinting his divine consciousness upward! His consciousness was blank for a moment, just like during the day, but this time, Shen Mu saw the complicated prohibitions in the tortoise shell! Although most of these prohibitions had been damaged, and most of them were dim, if it weren't for this, Shen Mu would not have been able to control it at all!

"Sure enough, it's tortoiseshell forbidden!"

Shen Mu silently thought, in addition to the tortoiseshell ban, there is also a part of the prohibition, giving him a different feeling, as if it seems that when the time is slightly out of order, this should be the mystery of the tortoiseshell's previous invisibility, specifically, this is not stealth, but due to the change of time, it can suddenly appear in front of him.

Put away the tortoise shell, Shen Mu already knew how to use this tortoise shell, not to throw it out directly like the big man in the daytime, but to completely urge it, let it exert the power of the tortoise shell forbidden, with the mysterious time ban, as a means of surprise attack.

Being able to unexpectedly harvest the black tortoise shell, Shen Mu is still quite satisfied, after all, this is something that was obtained for nothing, according to the threat that this black tortoise shell gave him before, Shen Mu estimated that if he used the black tortoise shell unexpectedly, even if it was a peak Qi Condensation Cultivator, he would suffer a big loss.

Taking out the Poison Emperor Sutra, Shen Mu began to read the first article, most of the demons in the Water Cloud Cave cultivated their bodies, and the Poison Body chapter just restrained them, Shen Mu wanted to go to the Water Cloud Cave, and naturally wanted to get the battle that might come, if he could prepare the poison medicine of the Poison Body Chapter, it would be a big help.

The flesh is the foundation of the cultivation of living beings, and the poisonous body chapter specializes in breaking flesh and blood, among which there are several poisons that make Shen Mu very interested, the first is the feather, which is made of various poisonous bird feathers, with blood yang flowers, Lanling grass, refining for seven hundred and forty-nine days, and it is colorless and tasteless.

In the Sea of No Return, poisonous birds are not uncommon, because of the harsh environment of the Sea of No Return, birds and beasts here have been living here for a long time, many of them are poisonous, but if you want to achieve the effect recorded, you need to be poisonous birds, Shen Mu has made up his mind to pay more attention to such poisonous birds in the future.

If he can refine the feathers, then Shen Mu does not need to open the Annihilation Realm, and he can also break his wrist with the Zhuji Monk, in the sea of no return, one more means means means one more life.

The second kind of poison is Qinghan, although the name is good, but Qinghan is an out-and-out killing weapon, refining with ice fruit as the main material, ice fruit is the most poisonous thing, growing in the land of extreme yin, and if you want the ice fruit to be born, at least more than 10,000 people must be buried here, the ice fruit contains severe cold and corpse poison, just a little, you can turn life into the living dead.

The reason why Shen Mu is interested in Qing Han is not only because of its strong toxicity, but also because it grows in the land of extreme yin, if Shen Mu wants to cultivate the Heavenly Cold Sutra, he will definitely go to find the land of extreme yin, and when the time comes, he will be able to search for ice fruits by the way, killing two birds with one stone.

Compared to the feather, the poison of the cold is more violent, it can directly kill the foundation monk, if you have this poison, Shen Mu will become extremely terrifying, can be called the king of the Yama, and the cold is not only colorless and tasteless, unless you reach the Yuanying monk, you will definitely not be able to perceive the existence of the cold.

Shen Mu has already decided that after joining the Shuiyun Cave, he will collect poisonous bird feathers, as well as several poisons such as blood yang flowers and Lanling grass, refine the feathers as soon as possible, and add life-saving means for himself.

In the sea of no return, Shen Mu no longer had the scruples of using demonic power, and extinguished the torch, Shen Mu took out the demonic power black ball left by Mologa and began to absorb it.

Now Shen Mu's demon power cultivation is in the eighth layer of Lingcai, generally speaking, the demon clan shows people with the body of a beast before reaching the transformation period, so Shen Mu's half-demon identity cannot be concealed, but this doesn't matter much, the non-return sea is originally the coexistence of human demons, and half-demons are not uncommon, and the human race and demon clans in the Shuiyun Cave are all there, and there are also half-demons.
