A few days later.

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

"Palace Master, this is the material you want, they are all ready, some are easier to get, I have prepared two copies. ”

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

Although his own strength has not stepped into the Transformation God Realm, his overall combat power has soared a lot, especially the Eternal Star Core, which is about to be filled with energy, and he has practiced the basic chapter of "Sword Dao True Solution", nine nine hundred and eighty-one swords, which is enough to fight against the powerhouses in the middle stage of the Transformation God Realm, even against the strong in the upper and late stages, he can also fight with them.

As long as the grade of the Purple Blood Demon Slayer Knife is improved, then the power of the basic chapter of "Sword Dao True Solution" will be increased again.

"Alright, you go out first, and don't let anyone disturb me. Lu Chen commanded.

After Lu Sheng left, Lu Chen casually arranged a formation to prevent interference, and then began refining.

For Lu Chen, refining weapons is no stranger, in the past, he was also a famous refiner, and this purple blood demon slaying knife was refined by him himself, and it was conceived with his own blood, and he had a heart with him, and it was much easier to refine.

In just half a day, all the materials were refined into liquid, and after that, Lu Chen inserted the Purple Blood Demon Slayer Knife into it.

Buzz!

When the Purple Blood Demon Slayer Knife came into contact with the metal liquid, it suddenly made a sizzling sound, and the blade was trembling violently, and countless ground patterns that had been integrated into the Purple Blood Demon Slayer Knife appeared one by one.

Rumble!

In just a few breaths, these dense earth patterns fused together, and with the help of the fire sky pattern, a new rune was actually born.

"Huh?"

Seeing this scene, Lu Chen was also a little stunned, he knew that it was possible to give birth to a heavenly pattern by fusing the ground pattern, but this probability was very small, so he had obtained so many ground patterns before, and he only directly integrated them into the purple blood demon slayer knife, and did not let them fuse.

It's just that I didn't expect that by chance, a new Tianwen was born.

Whew!

When the new Celestial Pattern was born, the Flame Celestial Pattern also appeared on the blade, and used its powerful flame power to continuously scorch the new Celestial Pattern, which seemed to help it forge and make it more stable.

Lu Chen's mind moved, a smile appeared on his face, and he immediately controlled the Flame Celestial Pattern and continued to scorch the new Celestial Pattern.

With the passage of time, the new celestial patterns and runes have become clear and clear, and they are completely covered on the blade of the Purple Blood Demon Slayer Knife, and at this time, Lu Chen carefully looked at these veins and found that this new rune seemed to be very close to the Flame Celestial Pattern, but it was not exactly the same.

"Hellfire Celestial Pattern?"

In Lu Chen's mind, four words came to mind.

As the former king of the gods, the Dragon Emperor, he was familiar with all the celestial patterns between heaven and earth, among which the celestial patterns of the flame system had nine paths, and this Dark Fire Celestial Pattern was one of them.

Even, he had been fortunate enough to see the Flame Celestial Pattern, so after some careful observation, he confirmed that this newly born Celestial Pattern was the Flame Celestial Pattern, one of the nine Celestial Patterns of the Flame System.

"I didn't expect that the Hellfire Sky Pattern could be born. Lu Chen guessed that it was very likely that he was affected by the Flame Sky Pattern, so he was able to give birth to the Flame Sky Pattern.

He was very happy in his heart, among the nine heavenly patterns of the flame system, the Flame Heavenly Pattern ranked ninth, and the Dark Fire Heavenly Pattern was the fifth-ranked existence, which was very powerful, and it could even be said to be the Heavenly Pattern that alchemists and refiners dreamed of.

With the Hellfire Sky Pattern, it can refine ancient elixirs, as well as special weapons.

Of course.

For Lu Chen, none of this mattered, the important thing was that he thought of a legend.

If you can collect all the celestial patterns of any series, there will be unexpected surprises.

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

The second is the fusion of the earth pattern, that is, the dark fire sky pattern, although this kind of sky pattern, although not as good as the ancestral pattern, but it is also extremely powerful.

After endless years of martial arts civilization development, the ancestral pattern has been very rare, almost impossible to be discovered, so the heavenly pattern born from the fusion of the ground pattern has become more and more precious.

Airplanes!

The two celestial patterns, intertwined with each other, covered the purple blood demon slayer knife, directly changed the appearance of the knife body, and forcibly widened the knife body by one centimeter, and the color of the entire knife body turned into flame red, and the whole body gave people a feeling of being burned by flames.

Meanwhile.

Lu Chen displayed a super refining technique and began to improve the quality of the Purple Blood Demon Slayer Knife.

Even, he used the special blood in his body to water the Purple Blood Demon Slayer Knife.

Ultimately.

After three days and three nights, the Purple Blood Demon Slayer Knife had a new look, and its quality had been improved to the peak of the Eighth Order, which was only one step away from the Ninth Order.

"Eighth Order?"

Lu Chen's eyes were fiery, staring at the Purple Blood Demon Slayer Knife, with the amplification of the two major celestial patterns, even if it was only the eighth order, it was much stronger than the ordinary ninth order.

Moreover, after this incident, Lu Chen was even more eager to obtain the other celestial patterns of the flame system, and he wanted to know what unexpected surprises would happen if he collected all the nine flame celestial patterns?

At that time, how powerful would the Purple Blood Demon Slayer Knife be?

Will he become a god soldier?

Of course, that's an afterthought.

Thundered!

The level of the Purple Blood Demon Slayer Knife was raised, triggering a vision of heaven and earth, and in the void clouds, there was a beam of flame light, swooping down, directly covering the refining room where Lu Chen was, and it lasted for half an hour.

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

In the air in the Tianlong Palace, the temperature rose sharply, and some weak martial artists couldn't resist it at all, and they went down the mountain one after another, and several deputy palace masters such as the immortal old man looked solemn, very worried about Lu Chen's safety.

"What's going on?" the undead old man muttered.

Lu Shengdao: "The palace master will be fine, right?"

Ke Chen and the old man with withered leaves also expressed their worries one after another, in short, the entire Tianlong Palace was panicked.

However, the head of the Wang family was extremely confident in Lu Chen, "The palace master is the chosen one, and it will be fine, do you still remember a legend in the past?"

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

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 a vision of heaven and earth, I guess it must be the palace master who has refined an incredible weapon to attract this flame light, right?"

As soon as these words came out, everyone's hearts were shocked.
