A few days later.

Lu Sheng sent all the rare materials needed by the palace master to Tianlong Palace.

"Palace Master, these are the materials you asked for. They are all ready. Some of them are easier to get. I have prepared two copies."

Hearing this, Lu Chen nodded, the grade of the Purple Blood Demon Slaying Knife should be improved.

Although his strength has not entered the realm of gods, his overall combat effectiveness has soared a lot, especially the eternal star core, which is about to be filled with energy, and he has also practiced the basic chapter of "The True Explanation of the Way of the Sword".

One sword is enough to fight against a strong person in the middle stage of the Transformation of God Realm, and even against a strong person in the late stage, he can still fight with them.

As long as the grade of the Purple Blood Demon-Slaying Knife is raised, the power of the Basic Chapter of "The True Explanation of the Way of the Sword" will be increased again.

"Okay, you go out first, don't let anyone disturb me." Lu Chen ordered.

After Lu Sheng left, Lu Chen casually arranged a formation to prevent others from disturbing him, and then started refining.

For Lu Chen, refining weapons is no stranger. He used to be a famous weapon refiner, and this purple blood demon-slaying knife was refined by him himself and nourished with his own blood.

It is much easier to refine it if you have a clear understanding with him.

In just half a day, all the materials were refined into liquid. After that, Lu Chen inserted the purple blood demon-slaying knife into it.

Buzz buzz!

When the Purple Blood Demon Slayer Knife came into contact with the metallic liquid, it suddenly made a sizzling sound, and the blade trembled violently. Countless ground patterns that had been integrated into the Purple Blood Demon Slayer Knife emerged one by one.

boom!

In just a few breaths, these dense ground patterns merged into one, and with the help of the raging fire sky patterns, a new rune was actually born.

"Um?"

Seeing this scene, Lu Chen was also a little dazed. He did know that it was possible for sky patterns to be born from the fusion of earth patterns, but the probability was very slim. Therefore, the many earth patterns he had obtained before were only directly integrated into the purple blood.

They were not allowed to fuse in the Demon-Slaying Knife.

I just didn't expect that by chance, a new sky pattern would be born.

Hoo ho ho!

When a new sky pattern is born, the fire sky pattern also appears on the blade, and uses its own powerful flame power to continuously burn the new sky pattern, seeming to help it be cast and make it more stable.

Lu Chen's mind moved, a smile appeared on his face, and he immediately controlled the raging fire sky pattern and continued to burn new sky patterns.

As time went by, the new sky patterns and runes became clear and completely covered the blade of the Purple Blood Demon Slayer Knife. At this time, Lu Chen carefully looked at these lines and discovered that this new rune

, seems to be very close to the Fire Sky Pattern, but it is not exactly the same.

"Underworld Fire Celestial Pattern?"

Four words appeared in Lu Chen's mind.

As the former King of the Gods, the Dragon Emperor, he was familiar with all the heavenly patterns in the world, among which there were nine fire-type heavenly patterns, and this Hell Fire Heavenly Pattern was one of them.

He had even been lucky enough to see the Dark Fire Heavenly Pattern, so after careful observation, he confirmed that the newly born Heavenly Pattern was the Dark Fire Heavenly Pattern, one of the nine flame-based heavenly patterns.

"I didn't expect that the Dark Fire Celestial Pattern could actually be born." Lu Chen guessed that it was most likely affected by the Fire Celestial Pattern, so the flame-type Celestial Pattern was born.

He was very happy in his heart. Among the nine heavenly patterns of the flame system, the Raging Fire Heavenly Pattern ranked ninth, while the Dark Fire Heavenly Pattern ranked fifth. It was so powerful that it could even be said to be the heavenly pattern that alchemists and weapon refiners dream of.

Pattern.

Possessing the Dark Fire Sky Pattern, he can refine ancient elixirs and special weapons.

certainly.

For Lu Chen, none of this was important. What was important was that he thought of a legend.

If any series of sky patterns can be collected together, there will be unexpected surprises.

However, he also knows that this kind of thing cannot be forced. After all, there are two forms of birth of sky patterns. The first is the birth of heaven and earth. This kind of sky patterns are often called ancestral patterns.

The second type is the fusion of earth patterns, which is the dark fire sky pattern. Although this kind of sky pattern is not as good as the ancestral pattern, it is also extremely powerful.

After endless years of development of martial arts civilization, the ancestral patterns have become so rare that they are almost impossible to detect. Therefore, the sky patterns created by the fusion of the earth patterns have become more and more precious.

Buzz!

The two large sky patterns intertwined with each other and covered the purple-blood demon-slaying knife, which directly changed the appearance of the blade. It widened the blade by one centimeter, and the color of the entire blade turned into flame red, giving the whole body a human-like appearance.

A feeling of being burned by fire.

at the same time.

Lu Chen used his super weapon refining skills and began to improve the quality of the Purple Blood Demon-Slaying Knife.

He even used the special blood in his body to water the purple blood demon-slaying knife.

final.

After three days and three nights, the Purple Blood Demon-Slaying Knife took on a new look, its quality improved to the peak of the eighth level, and it was only one step away from the ninth level.

"Eighth level?"

Lu Chen stared at the purple blood demon-slaying knife with fiery eyes. With the increase of two heavenly patterns, even if it was only the eighth level, it was much more powerful than the ordinary ninth level.

Moreover, after this incident, Lu Chen became even more eager to obtain other sky patterns of the fire system. He wanted to know what unexpected surprises would happen if all nine fire system sky patterns were collected?

How powerful will the purple-blooded demon-slaying knife be at that time?

Will he suddenly become a magic weapon?

Of course, this is a later story.

Boom!

The upgrade of the Purple Blood Demon-Slaying Knife caused a strange phenomenon in the world. In the clouds in the sky, there was a beam of flame rays of light that swooped down and directly covered the refining room where Lu Chen was, which lasted for half an hour.

During this period, no one can approach the refining room.

The temperature in the air in Tianlong Palace rose sharply. Some weak warriors could not resist it and descended the mountain one after another. The immortal old man and other deputy palace masters had solemn expressions, and they were very worried about Lu Chen's safety.

"What happened?" the immortal old man muttered.

Lu Shengdao: "Will the palace master be okay?"

Ke Chen and Old Man Ku Ye also expressed their concerns one after another. In short, the entire Tianlong Palace was in panic.

However, the head of the Wang family was extremely confident in Lu Chen, "The palace master is the chosen one, nothing will happen to him. Do you still remember a legend from the past?"

"What?" Several deputy palace masters were surprised and looked at the head of the Wang family.

The latter put away the Tongxuan Bell and grinned: "It was once said that whenever a peerless divine weapon was born, it would be accompanied by visions of heaven and earth. I guess it must be the palace master who refined the incredible weapon to attract

Is this a ray of flame?"
