After Lu Yu's injury was almost recovered, he didn't continue to cultivate, he had just seen Miao Chun's knife before cultivating, but it was just a high-grade magic weapon, and he had the ability to raise Miao Chun's knife to a level.

Therefore, Lu Yu wanted to take advantage of this time to upgrade Miao Chun's knife to the lower grade spirit weapon.

Thinking that he would naturally do it, Lu Yu spat out a breath of turbid air in his mouth, and after feeling that his state had reached its peak, Lu Yu stood up and walked to Miao Chun.

"Brother Miao, I won't tell you, I'm still a refiner, if you don't dislike it, why don't you let me upgrade the weapon you gave you to a low-grade spirit weapon! ”

Miao Chun was a little surprised when he heard Lu Yu's words, "You are still a refiner?! Brother Lu, I can't imagine it! You are still a versatile genius!"

Lu Yu listened to Miao Chun's words, and his old face turned red.

"Brother Miao, I'm really ashamed, I can't afford the weather, but I can still refine the weapon!"

Miao Chun held the knife in his hand and played with it for a moment, "Brother Lu, this weapon has been with me for a long time, but there are still a few hours before we start fighting for the Spirit Frost Grass, so it's better to wait for the Spirit Frost Grass to grab it before making plans!"

"Haha, don't worry, Brother Miao, this is not a refining weapon, it's just a weapon to upgrade and re-forge it, it won't take a long time, it's only about two to three hours!" Lu Yu said to Miao Chun with a confident face.

"Two or three hours?!Brother Lu, this ...... Miao Chun wanted to speak and stopped.

"That's it, in that case, Brother Lu, I'll leave it to you!" Miao Chun felt that he still had a weapon he used before, even if Lu Yu didn't improve well, he wouldn't delay anything, so Miao Chun handed over the knife in his hand to Lu Yu.

Lu Yu took Miao Chun's knife, "Brother Miao, don't worry! In three hours at most, I will definitely hand you a weapon that satisfies you!"

Miao Chun looked at Lu Yu's confident appearance, and his heart was completely relaxed, "Brother Lu, thank you for your hard work, it just so happened that I had some ores that I had obtained by chance before, and I also handed them over to you." ”

Miao Chun said, took out some ore and handed it to Lu Yu, Lu Yu looked at the ore Miao Chun took out and was shocked.

"Brother Miao, you can! Tianjing Stone, Yuxuan Stone, Jinyun Mine...... This is all good things for refining weapons!" Lu Yu took the ore that Miao Chun took out, and these ores were tightly tight, which only shocked Lu Yu for a moment.

"Brother Miao, without further ado, I'm going to upgrade your weapon, and we'll have a good chat after snatching the Spirit Frost Grass for a while!" Lu Yu said, just find a quiet place around and start refining the weapon.

"Whew!" Lu Yu exhaled a breath of turbid air from his mouth and sacrificed his Purple Mansion Blue Flame.

The blue flame exuded an amazing heat, and although Miao Chun and Lu Yu were a little far away, they still felt the power of the blue flame.

"What a strong flame!" Miao Chun was shocked in his heart, and then slightly distanced himself from Lu Yu, Miao Chun didn't dare to distance himself too far from Lu Yu, and Lu Yu couldn't be disturbed by others before refining the weapon, so Miao Chun chose a suitable place to guard Lu Yu.

"Melt!" After Lu Yu was ready, he threw the celestial crystal and gold cloud ore that Miao Chun took out into the blue flame, but the celestial crystal that Miao Chun took out was not enough, and Lu Yu himself put some into it.

As for the rain stone, with the gold cloud mine, the rain stone has become dispensable, and Lu Yu is too lazy to smelt the rain stone together, saving the waste of good ore.

After the celestial spar and golden cloud ore in the blue flame melted, Lu Yu sacrificed Miao Chun's knife, and then threw Miao Chun's knife into the blue flame.

"Zi!" The moment Miao Chun's knife entered the blue flame, the blue flame burned red, and after the time of a cup of tea, Miao Chun's knife gradually melted, and after the impurities in it were gone, Lu Yu put the previously smelted Tianjing and Jinyun ore and Miao Chun's knife together.

After mixing several different materials, Lu Yu depicted the appearance of Miao Chun Dao in the blue flame.

After the engraving is complete, the ore that has been smelted is brought together.

"The Twelve Emperors' Decision!" Lu Yu shouted, the blue flame dissipated, and a red weapon was exposed to the air, and with Lu Yu's shout, the water source was gathered to wrap the weapon that had been refined.

At this time, Miao Chun's knife had already exuded the aura of a medium-grade spiritual weapon, and Lu Yu was overjoyed, it seemed that his ability to refine the weapon had improved a little.

Lu Yu, who was upgrading the level of his weapon, suddenly thought of what Aotian had said to him.

"The real power of this day's acting technique is not in this small disguise, the specific power depends on your imagination!"

After thinking of this, Lu Yu Ghost made the gods use the Heavenly Acting Technique.

The Heavenly Acting Technique transformed into a person's appearance, grabbed Miao Chun's knife and began to forge it!

Lu Yu was also immersed in it, and his body involuntarily followed the Heavenly Evolution Technique.

"Bell!", "Bell!", "Bell!", ......

Miao Chun's knife was struck three times by the Heavenly Evolution Technique before it stopped, turning into air and dissipating between heaven and earth.

"Zheng!" Miao Chun's knife fell to the ground with a crisp sound, and Lu Yu also retreated from that wonderful realm.

Lu Yu looked at his hands blankly, stunned for a while, and only after about half an hour did Lu Yu react.

"What kind of power is this?!" Lu Yu couldn't figure it out.

"It's a disaster, Brother Miao's knife!" Lu Yu suddenly remembered that he was still upgrading Miao Chun's weapon.

After thinking about it, Lu Yu hurriedly went to find it, but fortunately, no one came to this place, and Miao Chun's knife lay quietly in the place where it was refined before.

Lu Yu picked up Miao Chun's knife and stroked it, "Alas, it's a pity, I didn't expect it to fall from a middle-grade spiritual weapon to a lower-grade spiritual weapon, it's really a pity!"

Lu Yu was holding Miao Chun's knife and his tone was full of regret, but when Lu Yu stroked Miao Chun's knife, he felt a mark on it, but he couldn't see it directly, just vaguely.

"This is ......" Lu Yu frowned, he knew that when he threw Miao Chun's knife into the blue flames, he didn't feel this mark, so where did this mark come from now? Could it be because of the Heavenly Evolution Technique?

Lu Yu's heart was full of doubts.

"Brother Lu?" Just when Lu Yu was puzzled, Miao Chun's voice sounded from behind Lu Yu.

After hearing Miao Chun's voice, Lu Yu threw away the doubts in his heart, anyway, he still has to refine the weapon, and he will try it with the Heavenly Acting Technique next time.

"Brother Miao, I'm really sorry, because I was distracted once, and the result was that your weapon didn't rise to the middle grade of the spirit weapon. Lu Yu said to Miao Chun with some embarrassment.

Miao Chun took the knife handed by Lu Yu, the knife was in his hand, Miao Chun stroked the blade, "The peak of the lower grade spiritual weapon!" Miao Chun's tone was full of surprise, and he didn't take Lu Yu's words to heart.

"Brother Lu, originally my weapon was just a mere magic weapon, but now that you have helped me rise to the peak of the lower grade spirit weapon, this is enough. Miao Chun laughed.

No matter where it is, he started practicing directly, "Zheng!" A knife light flashed, and the knife in Miao Chun's hand slashed out a sharp knife qi, and where the knife qi passed, the trees fell to the ground one after another.

Miao Chun's knife has increased more than three times compared to before Miao Chun's weapon was upgraded!

After the sword qi dissipated, Miao Chun's face was overjoyed, "Brother Lu, you are really amazing, this time, I am more sure to win the Spirit Frost Grass!"

Miao Chun walked up to Lu Yu and gave Lu Yu a bear hug, "Originally, I just thought that I could only increase my power by half at most, but I didn't expect you to give me such a big surprise!"

"Uh......" Lu Yu was speechless, "Brother Miao, it's just that the grade of the weapon has been improved a little, don't be so excited!"

"Brother Lu, don't you know, if you have this weapon......"

"Senior brother!"

Before Miao Chun's words were finished, he was interrupted by Liu Qian'er, Miao Chun put away the weapon casually, and Liu Qian'er also came to Miao Chun's side with the voice.

"I've seen this son!" After Liu Qian'er arrived at Miao Chun's side, she saluted Lu Yu again.

"Sister-in-law is polite, little brother, I can't stand my sister-in-law's courtesy!" Lu Yu hurriedly helped Liu Qian'er.

Lu Yu's sister-in-law also made Liu Qian'er blush, "What sister-in-law!" Liu Qian'er's voice was smaller than a mosquito, if it weren't for the fact that everyone on the scene had cultivated, no one would have been able to hear it at all.

Looking at Liu Qian'er's shy appearance, Miao Chun hugged Liu Qian'er in her arms, and hooked Liu Qian'er's chin with one hand, "Haha, what's the matter, don't you want to be with me?"

"I hate it!" Liu Qian'er's face turned even redder and buried herself in Miao Chun's arms.

"Haha......" Miao Chun felt that today was really a lucky day, and Liu Qian'er released his suspicions, and his weapon was also more than three times more powerful, of course, he had to thank Lu Yu for these, if it weren't for Lu Yu, these things would have been impossible to do so quickly.

"Senior Sister Liu!" Just as Lu Yu, Miao Chun, and Liu Qian'er were chatting, an inappropriate voice interjected into the conversation between the three.

Liu Qian'er looked at the source of the voice, and her face showed some disgust, "Wang Qiang, what are you doing!"

"You ......!" Wang Qiang's face changed instantly, but he recovered in a blink of an eye, "Haha, Senior Sister Liu, let me inform you, the Spirit Frost Grass is almost mature in half an hour, it's time to gather!"

"You ......" Liu Qian'er wanted to say something, but was stopped by Miao Chun, "Okay, I know, we'll be there soon!"

After Wang Qiang heard the reply, he didn't bother to stay any longer, "Farewell!" Wang Qiang clasped his fists with both hands, and left after saying goodbye.

After Wang Qiang left, Liu Qian'er asked Miao Chun, "Senior brother, why didn't you let me continue just now!"

Miao Chun patted Liu Qian'er's hand.
