Looking up at the black shadow, Ye Mu's pupils shrank suddenly, because he found that the severed arm of this Yin Spirit was slowly condensed again.

Although it grew very slowly, it really grew back, and this scene shocked Ye Mu.

If you can't kill this yin spirit, then you will be in danger, and the consumption is too large, and Ye Mu doesn't have much combat power anymore.

The Yin Spirit's face was distorted, as if he was suffering a great deal of pain, his red eyes glared at Ye Mu, and a few words came out of his mouth: "I...... Want...... You...... Target...... Blood ......"

"Hmph, do you want my blood?, then let you taste my sword ......" Ye Mu gritted his teeth, stood up straight, and the Xuan Qi gushed out again.

"Sword Qi River!"

With a wave of the arm, the Moyun Sword went from the bottom up, a sword was raised, a cyan sword light appeared, a crack was cut on the ground, and the black shadow covered the arm that was still growing, and with a jump, it left the place in a flash.

In the air, the sword light flowed, and a brilliant sword qi long river appeared, and a vacuum appeared around it, and the black shadow stood not far away, staring at the cyan long river.

"Go!"

Ye Mu's lips moved slightly, the Moyun Sword pointed forward, and the long river of sword qi turned into a streamer, attacking towards the black shadow.

Maybe because of the shock, or maybe because of the injury, the black shadow's speed was not as good as before, and he was firmly locked by the sword qi river, so he could only choose to take this blow hard.

"Boom!"

The black shadow's body pressed down, and his right hand punched out, and an invisible force rushed into the long river of cyan sword qi.

The long river of sword qi trembled slightly, but it did not dissipate, and a thundercloud appeared above the long river, but this thundercloud condensed very slowly.

Ye Mu frowned slightly, took out a thunder talisman, and injected Xuan Qi into the urging and shot towards the thundercloud.

"Zizizi!"

When the thunder rune reached the thundercloud, it burst open, and a ball of lightning appeared, speeding up the gathering of the thundercloud, and in just a moment, I saw several lightning bolts injected into the long river of sword qi.

"Boom ......"

Bursts of thunder sounded, and the sword qi surged, turning into a liquid long sword, slashing at the black shadow, and between the lightning flashes, it hit the black shadow.

"Bang ......"

The shadow was struck and slammed into the ground, smashing the ground into a humanoid hole, and a looming arc of electricity swirled around his body.

And his left arm also stopped growing, and the extreme destruction of thunder and lightning inhibited his growth, and Ye Mu finally sat on the ground, his face was like paper, and he gasped for breath.

After using sword skills one after another, he consumed too much Xuan Qi, and threw a Qingxin Pill into his mouth, although there would be impurities left, but there was no way at present, so he could only slowly remove it in the future.

The mystics in the world have not entered the Xuan realm, and it is best not to take the pill internally, because they cannot eliminate the impurities brought by the drug, and they will remain in the body, which will have a great impact on their future cultivation, so the mystics under the metamorphosis realm, very few people will take the pill, and most of them are external drugs.

However, Ye Mu's current situation has to use a Pure Heart Pill, which can calm the mind and concentrate the mind, and also has the effect of accelerating the recovery of Xuan Qi.

Feeling a cool feeling in his body, Ye Mu slowly opened his eyes and looked at the human-shaped pit, and suddenly his eyes froze.

"What about people?"

In the hole, the black shadow had disappeared, only some rags of clothes, looked around, quietly, Ye Mu stood up, looking uneasy.

The black shadow was obviously hit by himself, not to mention killed, it must have been seriously injured, why did it suddenly disappear without a trace, and he didn't even notice it at all, which made Ye Mu's back a little cold.

"Gotta get out of this place quickly!"

Unable to recover his state, he carried the Moyun Sword and walked towards the outside of the iron forest, not long after Ye Mu left, a figure walked out behind a thick iron tree, it was the black shadow Yin Spirit, he looked at the direction of Ye Mu's departure with a pair of red eyes, and the corners of his mouth suddenly opened, revealing a solemn smile.

Safely out of the Iron Forest, Ye Mu actually didn't have any injuries, he just received a punch from the black shadow, mainly because the consumption was too great, and the qi and blood in his body kept churning, causing some disorder in the Xuan Qi.

I found a corner, meditated cross-legged, and all the medicinal power of the Qingxin Pill was triggered, and the disordered Xuan Qi in my body was also back on track.

"Hoo ......"

Half an hour later, Ye Mu opened his eyes and slowly exhaled a breath of turbidity, his face was a little ruddy.

Glancing back at the direction of the Iron Forest, Ye Mu was a little afraid, the strength of the black shadow was definitely above the late stage of the Xuan Realm, if he could use the Xuan Qi, then Ye Mu would probably already be a corpse.

"These Yin Spirits can also regrow arms, which is too perverted......" Ye Mu muttered with a frown.

This is equivalent to having an immortal body, and these Yin Spirit thinking abilities are not weak, they will not only know how to resist, they will also dodge, and the most terrifying thing is their speed.

"The strength of the Yin Spirit I encountered is getting stronger and stronger, and if I go any further, I'm afraid I won't be able to withstand it!" Ye Mu stood up and said sadly.

It is true that the black shadow yin spirit encountered this time made Ye Mu use all his means, if he encountered a stronger yin spirit again, he would not dare to think about it.

"It's a pity that the inheritance of the Easy Sword Master can't be opened now, it won't help me......" Ye Mu looked down at the spatial ring on his finger and sighed.

Looking up into the distance, whether to continue moving forward or taking a detour to return became a question in Ye Mu's heart!

From the bottom of his heart, of course Ye Mu wants to move forward, but starting from reality, if he goes deeper, I am afraid that his life will be in danger.

"I don't know how many days have passed, let's find a place to cultivate for a while first!" Ye Mu looked around and swept in one direction.

............

Outside the boundless tomb, the outer courtyard of Cangxi College, and the back mountain bamboo garden.

Su Su was dressed in a light veil, looked at the scattered snowflakes falling in the courtyard, and whispered: "It's snowing, Ye Mu is in the boundless tomb, I don't know what happened?"

Now that it has entered winter, scattered snowflakes are swaying and flying in the sky, and it has been eleven months since Ye Mu came out of the Sword Pavilion.

During this period of time, Ye Mu has improved greatly in all aspects, but he still has not broken through to the Xuan Realm, and after the New Year, Ye Mu will be sixteen years old.

Su Su sighed, turned around and entered the room, there was a half-painted painting on the table, a tall figure holding a long sword was practicing in the snow, who is it not Ye Mu?

I have to say that Su Su's painting is still very exquisite, the portrayal of the characters and the outline of the scenery are all lifelike.

Su Su engraved all her thoughts about Ye Mu into the painting, glanced at the flying snow outside the house with beautiful eyes, and picked up the pen to sketch a little bit on the paper.

It has been forty days since Ye Mu entered the Boundless Tomb, and his own cultivation realm has not improved, and it seems that he has not improved in all aspects, except for the cultivation of the Ten Thousand Swords Returning Sect to the first layer realm.

At this time, Ye Mu was in a cave, which was temporarily excavated, halfway up the mountain wall, and the location was hidden and not easy to find.

Cultivating cross-legged, the Xuan Qi in the body continues to gather, fortunately, this boundless ancient tomb can still absorb the Xuan Qi, otherwise Ye Mu would have cried to death!

On the forty-first day, Ye Mu was still in a state of cultivation, but he didn't know that danger was approaching step by step......

The previous black shadow yin spirit hid in a corner, looking at the direction of Ye Mu's cave, his left arm had also regrown, and on his waist, there was an inconspicuous pattern engraved on his clothes, which was a circle, and inside was a rock character of a rock.

However, the Black Shadow Yin Spirit did not have the idea of going to the cave, but quietly retreated, maybe he knew that it would not be so easy to kill Ye Mu on his own.

On the forty-second day, Ye Mu opened his eyes and carefully looked at the surrounding situation at the entrance of the cave, before returning to the cave with peace of mind, drinking some water, eating some dry food, and continuing to cultivate.

Forty-three days......

Day 44......

Time after day, until the forty-seventh day, Ye Mu came out of the cave, because the cultivation of these few days not only restored his state to the peak, but also had a feeling of overflowing.

This shows that the bucket filled with water is about to be full, and Ye Mu is not far from breaking through the Transformation Realm, but there is a problem, that is, he can't hit the level of the Transformation Realm in this boundless tomb no matter what.

Because, Ye Mu didn't know how long it had been now, and he only had a feeling of overflowing now, and it was not time for him to impact.

Moreover, in the event that during the impact, the three-month period is reached, and the boundless tomb is forcibly teleported, the process of impact will be interrupted, and the cultivation will be regressive, and the meridians will be damaged at worst, and the fire will go crazy.

Therefore, even if Ye Mu was 100% sure, he would not choose to impact the Transformation Realm in this boundless ancient tomb.

Walking on the mountain road, Ye Mu didn't notice that two figures, one black and one white, were like ghosts not far behind him, following him.

These two figures were the beautiful female Yin Spirit and the Black Shadow Yin Spirit that Ye Mu had encountered before.

They did not attack Ye Mu, but carefully hung behind them, and if they looked closely, they would find that there was a red "Ji" pattern on the wrist of the beautiful Yin Ling.

"Rushuang, do you really think he can help us?" asked the Black Shadow Yin Spirit suddenly spoke up and looked at the white figure beside him.

"Well, I have a hunch that they can help us!" Ji Rushuang nodded slightly, with a hint of gleam in her eyes.

"Brother Lin Yan, if he can't help us in the end, how about taking his blood at that time?" Ji Rushuang tilted her head slightly, looked at Lin Yan and asked.

If Ye Mu saw this scene, he would definitely drop his jaw, the two yin spirits would actually talk to each other, and the object of the conversation was actually himself.

Ji Rushuang's eyes were different from when Ye Mu first saw her, with a hint of brilliance in her red pupils, as if she had her own consciousness.

Lin Yan nodded slightly and said, "Okay, then follow him first!"

Except for the lack of life breath on their bodies and the fluctuation of their Xuan Qi, the two of them were almost no different from a normal person.

Ye Mu continued to move forward without knowing it, this place was already close to the center of the Boundless Tomb, but it could be said that the area that Ye Mu had explored these days was estimated to be only one percent of the entire Boundless Tomb.

No one knows how big the space of this boundless tomb is, but it can be seen from the fact that the four major academies have only explored less than a third of the area over the years, and this space is very large.

In front of an abandoned complex, the layout of this place is supposed to be a castle, and although the walls are broken, some of the houses are not completely destroyed.

Standing in front of the broken city gate, Ye Mu did not immediately step into it, because no one had obviously been here yet, and there was no trace of being searched at all.

This city is not big, only a few hundred square meters in area, around the city, Ye Mu puffed out his cheeks, took out the Moyun Sword and walked in cautiously.

The wooden windows and doors of these houses have corroded to powder, and only one frame remains.

In one room, Ye Mu found a long sword without a scabbard, the hilt was light blue, and his blade had many chips, as if the sword had experienced a big battle and was full of scars.
