After Du Xuan left the Bloodline Cave, he did not return directly. Instead, he went to the Exercise Hall and found Li Xuan to get a batch of poisonous insects. These poisonous insects are of different use from the bloodline Cave. They are used to sacrifice and refine the ban. The bloodline of the Guworm is used to improve the quality of the headache chime material and give him the foundation for promotion to a higher level.

After all, if the material of the magic weapon itself cannot bear more restrictions, it will be useless no matter what, and the spiritual treasure cannot be promoted at all.

Li Xuan naturally had no words about this. Du Xuan quickly took enough. At this time, he no longer delayed his time and immediately turned back to the secret room of the Deacon Hall. After the secret room was blocked by Naihe Bridge, he began to sacrifice and refine the headache chime.

With the complete memory inheritance of Ma Tuling and the residual magic weapon Plague Bell, Du Xuan's sacrifice and refining of the Headburn Qing was very smooth. In just one month, the Plague Bell was completely destroyed and only a few minor fragments were left. At this time, the Headburn Qing's level was upgraded to the level of the top magic weapon, and the ban had reached twenty-three levels, and only one level was left to reach the Great Perfection.

This ban is not to be promoted to the spiritual treasure. It has enough poisonous insects, but Du Xuan is not in a hurry. He is planning to improve the quality of the material of the headache chime, and then continue to bless the ban in one go.

At this time, Du Xuan took out all the poisonous blood he obtained from the blood cave and opened it. Widths of poisonous blood breath scattered out, and the void curled like smoke, and various strange phenomena evolved.

Among them, there is no doubt that the blood of the colorful fairy is the most special and domineering, and its aura condenses into a colorful fairy butterfly about the size of a foot. As soon as it appears, other magical phenomena of the insects will disappear in time, as if they saw their own king, they all lie dormant and crawl under him, not daring to feel any pleasure.

Seeing this scene, Du Xuan hummed and instantly the light of the gods at dusk shot out, hitting the colorful fairy butterfly. "Puff--" At this moment, there was no room for resistance, and the strange phenomenon of the colorful fairy butterfly collapsed, turned into a bit of spiritual light, and retracted into the jade bottle containing its blood.

At the same time, Rong Chengzi couldn't help but groan, "It seems that Du Xuan is going to use the colorful immortal butterfly blood, he is really cautious. However, if you think this will completely eliminate my influence, you would be very wrong. Who will win the desperation? It's still behind us, let's take a look!"

In the Secret Room of the Deacon Hall, Du Xuan pulled his left hand, and the colorful immortal butterfly blood poured out of the bottle. Only one drop was Du Xuan stumbled his fingers, and a very thin sword light flashed out of thin air, splitting the drop of blood into two halves, half of which were put back into the jade bottle, and put them in close proximity. The other half was integrated with the other poisonous bloodlines, and then used the plague division of the Ten Thousand Poisons Sect to refine it.

After seven days and seven nights, Du Xuan's body seemed to have lost weight. The poisonous blood made of the enhanced magic weapon was completely refined. At this time, Du Xuan didn't care about rest, and brought a headache to the chime, soaking it in it. Then, he activated a series of secret techniques of the plague department and hit it in it, just like an ordinary blacksmith swinging a hammer, completely integrating the two, without distinguishing each other.

When each secret technique of the plague department is injected, poisonous blood is integrated into the headache chime. At the same time, the slightly more frequent materials in the headache chime are forced out, including liquid and dust particles, which fall to the ground.

This is a water-fighting process, but you can't be anxious. Once there is a deviation, you will destroy everything. However, Du Xuan is still in good time, but he is not short of patience, and he is not anxious or slow, and he is performing sacrifices with a very peaceful mind. Nearly a month has passed, and the poisonous blood has completely disappeared, and the quality of the headache has been improved.

At this moment, the headache chime was as red as blood, as transparent as jade. No matter how you look at it, you can't tell that it was made of metal and iron, and you think it was carved by jade. At this time, you knocked again, and the sound was crisp and pleasant, and the afterglow was long. It was also the best magic weapon of the twenty-three levels of prohibition, and its power was more than twice as high as before.

Du Xuan was naturally very satisfied with this result. At that moment, after a day of rest and after re-adjusting his condition, he began to combine crazy things, sacrificed and refined poisonous insects, turned them into layers of prohibitions, and blessed them on the newly promoted headache chime, and increased its magic weapon level.

After half a year, Du Xuan finally refined the ban on the headache chime to the 36th level, the best spiritual treasure, after spending more than 80% of the poisonous insect.

At this time, Du Xuan came out of seclusion without hesitation. There was no way, and he was a little disgusted after playing with the Gu insect for such a long time. He had decided that the remaining Gu treasures would be sacrificed and refined by Li Xuan and Rong Chengzi, but he was not ready to sacrifice and refine them.

However, his departure from the palace was quietly carried out and did not let the people in the Deacon Hall know, because she did not want to let herself fall into those ordinary things. Under the cover of Naihe Bridge, Du Xuan quietly came to the Palace of Execution and met with Li Xuan like a shadow.

"Brother Li, the headache has been completed. How are you doing here and how are you getting?" Du Xuan asked immediately.

"It's OK. Not only have I thoroughly learned Hu Chunlei's illusion, but I have also refined three Gu treasures. Although they are all one-time, they should be powerful!"

While speaking, Li Xuan shook his sleeves, an umbrella cover, a lonely boat, and a book appeared at the same time, suspended in Yukon. It was the blue sky that the God of Mind and Du Xuan carefully sensed, and found that except for the lack of the true meaning of the three great divine waters, it was almost the same as the ones he sacrificed and refined, and even it was even better.

At this moment, Du Xuan did not hesitate and took action to separate the Biluo Divine Water, the Light and the Yellow Spring Divine Water stored in his body, and penetrated them into it, sublimating their power again.

These are the three drops of remnants that Emperor Dongyin gave him. They are not low-level counterfeits that Du Xuan himself practiced. Their power is really terrifying.

Immediately afterwards, Du Xuan took out another jade bottle from his arms, which was the one in the collection of colorful immortal butterflies' blood and handed it to Li Xuan. After explaining the situation to him, Li Xuan instantly understood what Du Xuan meant.

"Do you think the real colorful fairy is not dead yet?"

"That's not. I can't be sure about this, but it's just a precaution!" Du Xuan shook his head slightly and said, "Who those who are about to become immortals can have few killer moves and life-saving methods. We must be wary of it. If we kill the fake Sima Yi before we beat the front and get the advantage of the Qicai Fairy later, then the reputation of our brothers will be ruined!"

"Indeed, this is the reason!" Li Xuan nodded when he heard this.
