Li Yi thought of the experience of refining the Giant Spirit Sword, at that time, the Giant Spirit Sword also refused to admit the master, but in the end it was surrendered by him, relying on a piece of black iron.

This piece of black iron was an opportunity to change his fate, and passed on to him an ancient miracle "Demon Refining Technique".

All along, Li Yi tried every means to unlock the secret of the black iron piece, but he didn't succeed, he only knew that it would definitely not be so simple to be able to hide the iron piece of the anti-heaven technique such as "Demon Refining Technique".

At first, the giant spirit sword refused to admit the master, but when he saw the black iron piece, it was like a mouse seeing a cat, trembling, and suddenly he couldn't be more honest.

In other words, the black iron piece is at least a higher-level existence than the spirit weapon.

"What could it be above the spiritual weapon?" Li Yi once thought that the heaven-level magic weapon was the best magic weapon, but later after the guidance of the workers, he knew that there was a spiritual weapon on top of the magic weapon.

But what else is on the spiritual weapon, he doesn't know, although he asked the worker, but the other party is also vague, only said that the existence of the transcendent spiritual weapon is just some ethereal legends.

But Li Yi felt that the legend may not be ethereal, otherwise why would the Giant Spirit Sword bow its head and surrender to a mere piece of iron?

"If my alchemy can be cultivated to a very high level, maybe I will be able to unlock the secret of the iron piece, and ......maybe even repair it," Li Yi thought secretly.

It's just that he can't even repair the spiritual weapon now, and it is really difficult to repair the black iron piece, unless there is a great opportunity, there is no decades, or even hundreds of years of hard work, don't think about any gains.

Putting this somewhat distant dream aside for the time being, Li Yi first took out the wooden box containing the Thunder Spirit Needle.

The wooden box trembled in his hand, and the seal on it flickered with lightning, sometimes bright and sometimes dark, and it was almost time to run out of oil and lamp.

Li Yiguang was holding the wooden box, and he could feel the violent impact coming from inside, making a thumping sound, if it weren't for his strong body, I am afraid that even his bones would be shattered.

"This Thunder Spirit Needle is really violent, compared to it, the Giant Spirit Sword is very tame!" Li Yi was secretly frightened, and he was a little unsure for a while, not knowing if the black iron piece could deter it.

Just as he was hesitating, the wooden box suddenly made a clicking sound, and the seal on it began to crumble, like the earth cracking, and a dazzling light was shining inside.

Knock knock knock!

The Thunder Spirit Needle slammed even harder, it already felt free, and it was impatient to break through the restraints.

"Not good!" Li Yi was taken aback, and before he could react, a purple light burst out in front of him.

Bang!

The wooden box exploded, and the Thunder Spirit Needle carried a powerful force and shot towards Li Yi's face.

It seems that in his opinion, Li Yi is the culprit who bound him, and now that he has broken through the shackles, he naturally wants to seek revenge on Li Yi.

Li Yi hurriedly urged King Kong not to break the supernatural power, his face was full of golden light, only to hear the sound of the bell, the thunder spirit needle was suddenly shocked back, although Li Yi was also shocked back two steps, but unharmed.

Previously, the Thunder Spirit Needle could still pierce his skin, leaving a little blood mark, but now that he had cultivated the Vajra Incorruptible Divine Power, there was not even a trace of blood.

The Thunder Spirit Needle has a high spirituality, and if he can't succeed in one blow, he knows that Li Yi is not easy to match, so he snorted and shot away in the opposite direction, wanting to fly away.

"Where are you going!" Li Yi urged the Wind Divine Power and chased after him, but although his speed was extremely fast, he was a step slower than the Thunder Spirit Needle.

The speed of the Thunder Spirit Needle had surpassed the sound, and in an instant, it was already a hundred feet away.

Seeing that he was about to lose the trace of the Thunder Spirit Needle, Li Yi didn't think much about it, took out the black iron piece, and threw it.

With this throw, Li Yi used all his true qi, plus the strength of his physical body, and the power of King Kong's incorruptible supernatural powers, and the three were one.

The black iron piece suddenly turned into a black shadow, quickly overtaking the thunder, and pounced on the thunder spirit needle.

A powerful coercion overwhelmingly pressed towards the Thunder Spirit Needle, invisibly, it was like a big mountain covering the top of the Thunder Spirit Needle's head.

Although the black iron pieces were still dozens of feet away, the speed of the Thunder Spirit Needle had been greatly affected and slowed down.

Generally speaking, if it encounters a natural enemy, then the prey will run faster, but the black iron piece seems to be an even more terrifying existence than the natural enemy, and the thunder spirit needle actually lost the courage to escape, felt extremely frightened, kept trembling, and staggered.

Soon, the black iron piece collided with it, like a magnet, firmly absorbing the Thunder Spirit Needle.

Lei Lingzhen was honest and didn't dare to resist at all, he was a raging tiger before, but now he has become a tame kitten.

Li Yi immediately arrived, grabbed the black iron piece and the thunder spirit needle in his hand, and couldn't help but breathe a sigh of relief.

"Tell you to run, now you know how good I am, right?" he glared at the Thunder Spirit Needle.

The Thunder Spirit Needle was dull and looked very sluggish.

Li Yi received the King Kong not bad magic power, pierced his finger, and dripped a drop of blood on the thunder spirit needle.

The Lei Ling Needle struggled weakly, but in the face of the shock of the black iron piece, he didn't make much resistance after all, and was forcibly sacrificed by Li Yi, laying a blood brand.

Li Yi suddenly felt that he had a feeling of blood connection with the Thunder Spirit Needle, like a finger.

"Go!" Li Yi pointed to a boulder in front of him.

The Thunder Spirit Needle didn't move.

Li Yi forced the black iron piece towards it.

The Thunder Spirit Needle flew out slowly, flew halfway, and suddenly accelerated, and there was an explosion in the air, and the Thunder Spirit Needle disappeared.

In the next moment, the boulder had been reduced to pieces.

"Haha!" Li Yi laughed happily, the power of the Thunder Spirit Needle far exceeded that of the Giant Spirit Sword, it could be said that it was unpredictable, and with the Wind Divine Power, it was absolutely invincible to use it for sneak attacks.

Only the Thunder Spirit Needle looked very unhappy, it had just gotten rid of the seal of the wooden box, and encountered an even more terrifying black iron piece, which made it feel like it wanted to cry without tears, as if it would never be able to get rid of the fate of being enslaved.

Li Yike couldn't care so much, so he directly put the Lei Ling Needle into the storage bag, and took the black iron piece to look at it carefully.

Every line and outline on it had already been engraved in his mind, but he still couldn't figure out what this piece of iron meant, and what kind of power it contained.

Why are both the Djinn Sword and the Thunder Spirit Needle afraid of it?

This is the biggest doubt in Li Yi's heart, if he can figure this out, he may be able to find a way to repair the black iron piece, and then grasp the mysterious power in it.

It's a pity that after studying for a long time, I still don't have a clue, so I can only put it away and wait for any chance in the future, maybe I can solve my doubts.

The Thunder Spirit Needle was successfully cultivated, and then Li Yi's energy was mainly focused on cultivating the Decepticon Fist, which could not only maximize his physical strength, but also temper his physical body and stimulate the potential of his bloodline, which could be said to kill two birds with one stone.

The Decepticon Fist requires the blood of the royal family to be able to cultivate, but among the royal family, there are very few people who practice this boxing technique, not only because it is difficult to cultivate, but more importantly, its shortcomings are too great.

The first is the melee technique, and the second is that the damage to the physical body is too great, it can be said to be a kind of exercise that injures the enemy by a thousand and damages itself by eight hundred, and the power that erupts can not only destroy the enemy, but also destroy itself.

If Li Yi hadn't cultivated the Vajra Immortal Divine Power, I'm afraid he wouldn't have the courage to try.

But with King Kong not bad supernatural power protection, the shortcomings of the Decepticon Fist have instead turned into advantages, and the process of cultivation is like a kind of high-intensity training, so that his physical body will not only not be damaged, but will become more tenacious.

In addition to cultivation along the way, there were several times when Li Yi was discovered by the Huoxin Bird, but he had already transformed into a life and deceived the Huoxinnio's detection, and none of the Huoxinniao blew himself up on his head.

This gave him a lot of confidence, since he could deceive Huoxin Bird, then he should also be able to deceive Wu Suo.

Going deeper and deeper in the Netherworld Forest, the distance from the 100,000 Mountains is getting closer and closer, on this day, Li Yi cultivated by a river, and in the middle of the night, he finally cultivated the Decepticon Fist to the realm of Dacheng, and his power increased again.

With King Kong's magic powers, a punch blasts out, just the fist wind can shatter the boulder, not to mention the boulder, even a piece of gold, which will be shattered by his fist wind.

Li Yi was satisfied, sweating profusely, so he jumped into the river and took a bath.

Suddenly, he noticed a strange phenomenon.
