Lin Yuan had already thought about it, since the ore on his body couldn't make any large weapons, then he would get a smaller weapon first.

The black stone was burned in the crater for a full hour before it turned completely red.

After that, Lin Yuan first manipulated the black metal plate to grow larger, and then put the red-hot black stone on top of the black metal plate.

Then, he controlled a yellow metal block the size of a fist and smashed it hard at the black stone.

"Bang!bang!bang......"

The gold metal was like a hammer, striking the reddish black stone and changing its shape.

After half an hour, Lin Yuanfang smashed the black stone into a satisfactory shape...... A black embroidery needle more than three inches long and thinner than chopsticks!

This black embroidery needle is the weapon that Lin Yuan wants!

"Very good!" Using his aura to control the black embroidery needle, after putting it in front of his eyes and looking at it carefully for a while, Lin Yuan nodded with satisfaction.

"Whoosh!"

Then, he controlled the black embroidery needle and shot directly at a boulder next to him, the speed was faster than the previous black stone form, I don't know how many times faster, if you don't observe carefully, even Lin Yuan, it will be difficult to find it, and it is even better to use it to sneak attack.

"Whew!"

The next moment, the black embroidery needle was like hitting tofu, easily piercing the boulder next to it!

"Haha, it's good!" After seeing the effect of the black embroidery needle, Lin Yuan's huge bull's eyes couldn't help but show ecstasy.

In the previous battle with that demon monkey, the reason why his black stone couldn't hurt that demon monkey was mainly because the speed of the black stone was too slow, slow enough for the demon monkey to have enough time to react and easily knock it away!

But if his attack speed is fast enough, the situation is probably different!

He believed that with the astonishing speed of this black embroidery needle, even the demon monkey would be difficult to react to, let alone intercept it easily!

And if it is in the case of a sneak attack, then the demon monkey should be even more inescapable, and it will inevitably be hit!

In other words, with this black embroidery needle, Lin Yuan's certainty of defeating the demon monkey was much greater!

However, Lin Yuan is not satisfied!

He hoped that this black embroidery needle would not only have amazing speed, but also have amazing power, and strive to be able to kill that demon monkey with one blow!

Because you must know that this embroidery needle can only be regarded as a hidden weapon used for sneak attacks, and it cannot be regarded as a weapon at hand.

If he can't kill the Monkey King with one blow, even if his sneak attack is successful, after the other party reacts, with that powerful iron rod, I'm afraid he can still compete with him!

And the best way to increase the power of the black embroidery needle is naturally to incorporate spell attacks into it.

Lin Yuan's gold-based spell can increase the sharpness and hardness of the black embroidery needle.

Wind spells, on the other hand, can increase the speed of the black embroidery needle, making it even more elusive and difficult to defend.

Thunder spells and fire spells can not only increase the speed of the black embroidery needle, but also enhance its destructive power.

Even earth-based spells can increase the weight of the black embroidery needle, increasing its destructive power.

There are only water-based spells and wood-based spells, which don't seem to have much effect.

However, as long as he can fuse the five spell attacks in front of him on the black embroidery needle, then the power of the black embroidery needle is estimated to reach a very terrifying level, and it should be enough to deal with the monkey king.

So immediately after, Lin Yuan directly began to try to integrate the power of various spell attacks into the black embroidery needle to continuously improve its power.

At the same time, the bison that led Lin Yuan was standing aside, watching Lin Yuan's strange behavior in a daze.

Although it didn't know what Lin Yuan was doing, it always felt like it was very powerful.

Therefore, Lin Yuan's every move, all unconsciously, was quietly imprinted in the mind of this bison, and then prompted this bison's spiritual wisdom to gradually open up at a faster speed than his companions, so that many years later, this unknown bison also grew into a great demon king who was rampant in one world......

......

Time flies.

Before you know it, the night has passed.

This night, Lin Yuan had been standing in the crater, bathed in the endless starlight on the vast sky, constantly practicing the technique of controlling the black embroidery needle.

The next morning, when the morning sun was rising, Lin Yuan finally stopped practicing.

At this time, he was already able to skillfully control the black embroidery needle, and integrate all kinds of different spell attacks into it!

"Moo!"

Looking at the red sun that had just risen from the horizon, Lin Yuan suddenly looked up to the sky and roared, meaning to tell the bison next to him to go with this king and settle accounts with the monkey!

"Moo!"

The bison immediately replied, this guy felt that after watching it all night, he also felt that he had gained a lot, so his voice was also full of excitement.

At the same time, the other bison sent by Lin Yuan all returned to the gathering place last night.

After discovering that the leader Lin Yuan was missing, they were also a little overwhelmed, so they had to continue to stay at the gathering point and wait silently.

It didn't take long for Lin Yuan to come back with the bison who led the way.

"Moo!Moo......"

Seeing Lin Yuan coming back, the herd immediately surrounded and let out an excited roar.

"Moo!"

Lin Yuan looked around at the cattle and roared, which means that the little ones, go out with this king, step on that spiritual mountain, and capture the monkey king alive!

That demon monkey may have been in contact with humans, and it may have the information that Lin Yuan wants in its head.

Therefore, if possible, Lin Yuan didn't want to kill the monkey king directly, but was ready to ask for those human-related information from the other party's mouth first.

"Moo!Moo......"

Hearing Lin Yuan's confident roar, the cattle couldn't help but let out an excited roar.

Then, under the leadership of Lin Yuan, the entire herd rushed towards Lingshan not far away.

......

At the same time, on that spiritual mountain, the silverback gorilla guarding the outermost part of the cottage saw the herd led by Lin Yuan from afar, and his eyes couldn't help showing horror, and he hurriedly screamed and alerted his companions.

"Whoosh!"

The next moment, a yellow figure suddenly rushed out of the core cave.

This figure is naturally the monkey king.

"Roar!"

Seeing that Lin Yuan actually led the herd to kill him openly, the Monkey King couldn't help roaring angrily, and then directly stepped on the red metal plate, held the black iron rod, flew in the air, and quickly rushed towards Lin Yuan and them.
