In Yuan Yi's understanding, in this world, all living beings have souls, and living beings can survive without their bodies, but there has never been anyone who only retains their bodies, but their souls are completely gone, and they can still live, even zombies, they are just missing souls, but their souls are complete.

If a creature is compared to a computer, the soul is equivalent to a central processing unit, and there has never been a computer that can run without a central processing unit.

Therefore, he was sure that the Soul Slaying Knife could work, and the Soul Slaying Knife could kill almost all the souls in the world, and only the Dao Ancestor whose soul was in harmony with the Great Dao could be killed without fear of the Soul Slaying Knife.

As soon as the soul slaying knife came out, the vicinity that was already full of a lot of negative emotions dropped sharply at this time, and the temperature dropped sharply, falling to the point that the heart of the strong body on the side couldn't help but rub his arm, glanced at the soul slaying knife, and was a little surprised, according to the reason, Yuan Yi is a Buddhist monk, it is impossible to send out such a cold attack.

Before he could say anything, the Soul Slaying Knife slashed at the nearest Shadow Clan, and at this moment, this Shadow Clan was like a rag, torn apart violently, turned in half, and quickly returned to nothingness.

"It's done", Xin Yi showed a hint of joy, but when he just turned his head, he saw a strange scene, Yuan Yi's face flickered like a trick at this time, and gradually distorted.

The Soul Slashing Knife was quickly withdrawn, and it sank into the relics again, and Yuan Yi suddenly let out a wow, spurting out a large mouthful of blood, completely black blood.

"What's going on", Xinyi hurriedly asked.

"Nothing". Yuan Yi said perfunctorily, his situation was not very good at this time, it was not that the other party's divine soul was too strong. caused his soul to be injured, but his soul turned into a soul slashing knife, and when it slashed through the body of the Shadow Clan, it was generally in close contact with the body of the Shadow Clan, and all kinds of surging negative emotions in the Shadow Clan's body surged towards Yuan Yi in an instant, and these negative emotions were too strong. made his three bodies too late to absorb and purify, which hurt his soul.

Fortunately, his soul is guarded by the golden wheel of merit, which keeps the Lingtai Qingming. I didn't get lost in the sea of negative energy.

"Retreat first", Yuan Yi once again sacrificed the golden wheel of merit to resist all the approaching shadow clans, and the two quickly retreated. These Shadow Clans probably also realized that Yuan Yi was not easy to mess with. So he paused and didn't catch up.

Retreated to the teleportation array, so that as soon as there was a stir, he could immediately leave through the teleportation array, Yuan Yi let his heart protect the Dharma, sat cross-legged, and began to breathe.

Soon, days passed. Yuan Yi woke up at this time, and he was a little afraid. The negativity of the Shadow Slayer was so strong that it could swallow him up at any moment, turning him into a walking corpse.

Konichi asked, "Are you okay?"

"It's okay, I'm really sorry, I tried my best, but I couldn't get those shadow clans."

When Xin heard this, he shook his head and said, "It's okay, just find another way, I feel guilty if I hurt you, I know a way to bypass those shadow clans and enter the center of the cave, I will take you there, you can practice there until you want to leave."

Yuan Yi shook his head, he never said that he did it, this was a deal, in exchange for the opportunity to cultivate in the cave sky, the shadow clan did not solve it, and he was embarrassed to accept this benefit in vain, so he said, "I don't plan to give up just yet."

"Do you have any other means", Xinyi is also very staggered about the many means of Yuan Yi.

"No, I'm poor in skills, but with the Golden Wheel of Merit, although we can't kill those Shadow Clans, we can drive them away and find the secret of the birth of the Shadow Clan."

"The secret of birth?".

"That's right, you said it, these Shadow Clan did not appear out of thin air, they need to go through very harsh conditions before they can be born, as long as we find this condition, we will definitely be able to find a way to kill Shadow Clan."

"So what are you waiting for", Xinyi became a little excited, and it was an exciting thing to think about being able to move freely among a group of terrifying shadow clans.

At that moment, Yuan Yi sacrificed the golden wheel, and the two of them went all the way, because of the golden light of merit, no shadow clan could hurt them occasionally, just like Moses divided the sea, wherever the two went, the overwhelming shadow clan hurried to avoid them one by one, leaving a straight path for the two of them.

When he arrived here, Yuan Yi found that the number of the Shadow Clan was probably beyond everyone's imagination, and it had reached the level of disaster, even more than the Golden Silkworm Mother, as long as a world gave birth to a Shadow Clan, and the people of this world had no way to destroy the Shadow Clan, it was almost certain that this world would be destroyed in the hands of the Shadow Clan, and the first Shadow Clan to be born could expand the population by constantly killing.

In this world, there were originally not many living beings because of the terrible pressure, but now, it is almost invisible, and it has basically become the belly of the golden silkworm mother.

Yuan Yi seemed to have seen the pained expressions of the monks of Nalanda Temple, after such a catastrophe, this Fang Dongtian either couldn't recover, or after completely recovering, hundreds of thousands of years had passed.

If you want to find the source, it's very simple, where the shadow clan is dense, go there, according to Yuan Yi's words, this group of ghosts is not idle and has nothing to do to get together to play cards, they get together so much, there must be a cat immediately, maybe that's their lair, maybe that's where they were born.

This cave is so big that it is beyond Yuan Yi's imagination, because the two of them have the golden wheel of merit, so they are unscrupulous in the sky flying at a very fast speed, but unfortunately, after flying for a long time, they have not found the place where the root cause is, and the flying black shadow clan is scurrying in front of Yuan Yi and them, blocking their sight, making Yuan Yi almost think that he has black phobia, and as long as he sees black in the future, he will be disgusted and want to vomit.

Searching hard, after the Buddha Yuan was exhausted, he found a place to rest, so he searched day and night, and this day, it was finally a little eyebrow-raising.

Ahead, there was an extra grove.

This forest, Yuan Yi can only be described as an iron forest, all the trees are black, and dense, making Yuan Yi's black phobia aggravated, the tree is bare, there is no leaf, the tree body is extremely hard, this is the most fundamental reason why Yuan Yi named it the Iron Forest, his body is so powerful, a punch bombarded one of the trees, the tree did not move, even symbolic shaking refused.
