Naturally, Li Fuchen did not know about his wanted by the Tiansha gate.

In fact, Li Wuxue's death had nothing to do with him. Although he wanted to kill each other, he died in the hands of demons.

It took half a month for Li Fuchen to combine nine kinds of yellow top level sword patterns into black iron sword patterns.

The black iron sword pattern is extremely complicated, which clearly contains a trace of mystery.

Take out a yellow top step sword blank, and Li Fuchen begins to refine the black iron sword pattern on it.

It can be seen to the naked eye that on the sword blank, there are lines that emit black light. Some of these lines are as straight as a sword, some as curved as a knife, and some as dense as tadpoles.

At the same time, a strange wave rippled.

This time, it took Li Fuchen five hours to refine.

At the moment of refining, the air of the sword is penetrating and the sword is booming. The weight of the sword blank is more than five times heavier, and it is no longer so light in the hand.

"Is this black iron sword pattern?"

The sword pattern disappears, and the sword blank in Li Fuchen's hand has changed greatly. It seems that there are many sharp edges in the places where the front has not been opened. The cold light flashes from time to time, and it no longer looks like a sword blank, but has the temperament of a sword.

"Although it can't match the pattern of black gold sword, it is more comprehensive than that of black gold sword."

The black gold sword pattern contains sharp edge, weight and tenacity.

The black iron sword pattern not only contains sharp edge, weight and tenacity, but also contains the characteristics of condensing gas and conducting gas.

As soon as his wrist shakes, Li Fuchen stabs the void with a sword.

Before the sword arrives, Qi comes first. In the void, the sword Qi flashes away.

"The black iron sword pattern makes it easier to condense the sword Qi, and the forced sword Qi is also very smooth. It is worthy of the black iron sword pattern."

Li Fuchen nodded secretly.

Now that you have mastered the black iron sword pattern, the next step is to refine the black iron sword pattern on the bone marrow.

Li Fuchen doesn't know whether his bone marrow can bear the black iron sword pattern, but he always wants to try.

Sitting cross legged, Li Fuchen closed his eyes.

Under the state of internal vision, Li Fuzhen's true Qi flowed out from the Dantian and meridians and swam towards the bone marrow.

After several breaths, Li Fuchen couldn't help but take a breath of cold air.

The black iron sword pattern on the bone marrow is much more painful than he imagined. It is not only painful, but also very itchy. It seems that there are countless cannibals eating the bone marrow, which makes people wake up from the inside out.

Endure the pain and itch, Li Fuchen continues to refine the sword pattern.

At this time, if anyone can see through the skin, we can find that on Li Fuchen's bones, a line of lines with black luster spread out.

"Should be able to bear it!"

Seeing that there was no problem with bone marrow, Li Fuzhen relaxed a little.

He was really afraid that the bone marrow would collapse and disintegrate before the black iron sword pattern was condensed.

There's a bone marrow problem. That's a big problem.

What Li Fuchen didn't know was that although the bone marrow of a warrior was not as hard as some high-grade metals, it was more suitable for condensing utensil patterns because it was often moistened by genuine Qi. The only drawback was that not all the weapon patterns were suitable for refining on bone marrow.

If Li Fuchen randomly finds a mysterious low-level sword pattern and condenses it on the bone marrow, ten out of ten will have a big problem.

The black iron sword pattern is not the same. It is a sword pattern suitable for human bone marrow, which was developed by predecessors for a long time. As long as you learn from it, there will be no big problem.

It is not a matter of a day to refine the black iron sword pattern on the bone marrow. It took a day for Li Fuchen to refine 10% of the black iron sword pattern on his bone marrow.

The bone marrow in the black iron sword marrow chapter actually means bone. No matter the bone marrow has bone marrow or bone without bone marrow, it is the same in the chapter of black iron sword marrow. Because the bone marrow is very fine, refining the sword pattern of black iron also needs to be very fine, and there is no recklessness.

After all, this is not to condense sword patterns on metal. The structure of metal is very simple, and it will not have any impact. However, bone marrow has a great impact on human body. If it is not good, bone marrow will become a waste person in an instant.

"A black iron sword pattern, I feel that the bone marrow has become heavier, but it is not clumsy, and the explosive force is stronger."

The true Qi slowly withdrew from the bone marrow, and Li Fuchen carefully felt the abnormality of the bone marrow.

Chuckle

He raised his palm and stretched out a finger. A ray of sword Qi was blooming from his fingertips, sharp and pressing.

The heart thought moves, the sword spirit shoots out.

Poop.

Ten meters away from the ground, was shot a finger size deep hole.

"It doesn't seem to be weak."

Li Fuchen took a deep breath, and the real Qi of burning the sky was running. A wisp of sword Qi came out of his body. In the blink of an eye, there were more than ten sword Qi around his body.

"Go!"

My mind moved, and more than ten swords fired fiercely, shooting the ground more than ten meters away into a hornet's nest.

"It is worthy of the black iron sword pith, but it has created a similar effect of wanjian Guizong."A terrible light flashed in Li Fuchen's eyes.

Ten thousand swords belong to the clan. They are extremely powerful. They have cultivated to the level of great elder Zhao endless. The secret method works. There are thousands of sword Qi all over the void, making the enemy have nowhere to hide and nowhere to hide. Whether it is the frontal attack power, but the range attack power, it is enough to astonish the world.

And black iron sword pulp also has such effect obviously.

At present, Li Fuchen has only condensed 10% of the black iron sword pattern. If the complete black iron sword pattern is condensed, not to mention thousands of sword Qi, it should be no problem to send out hundreds of sword Qi to attack the enemy.

As time went by, the black iron sword pattern became more and more complete on Li Fuzhen's bone marrow.

Half a month later, Li Fuchen has condensed 90% of the black iron sword pattern.

"Come out!"

The true Qi of burning the sky moves and infuses it into the bone marrow. At the next moment, dozens of sword Qi are all over Li Fuzhen's body.

These swords are faintly black, just like a real iron sword.

Sonorous, sonorous, sonorous

On the opposite side, a piece of yellow top metal was splashed with sparks. When the sword gas was consumed completely, the yellow top metal had already become a hornet's nest, pitted and crisscrossed with sword marks.

"Interesting!"

Li Fuchen's eyes are bright.

Black iron sword spirit is very powerful. Unfortunately, it can't contain sword meaning. If it can, it will be more powerful.

But it doesn't matter. With the black gold sword, you can still use the sword technique.

Thinking of doing it, Li Fuchen pulled out the black gold sword, and the black iron sword spirit poured into the black gold sword.

Hum!

The black gold sword vibrates and emits a sharp sword spirit.

"Go!"

With a whirling sword technique, the potholed yellow top metal is directly blasted into a ball of molten iron, which is more than twice as powerful.

"In the future, black iron sword pith can be used as an assassin's mace. It's better not to expose it until the critical moment."

The pith of black iron sword is too powerful. Because it doesn't need to be stimulated like Xuanlong secret method, it can be used in combination with Xuanlong secret method. You only need to infuse Xuanlong's true Qi into black iron sword pith to force out more powerful sword Qi.

A week later, Li Fuchen finally condensed the complete black iron sword pattern on the bone marrow. At this moment, Li Fuchen was like a sword, a peerless sword. His actions and actions brought a terrible sense of depression.
