Refining weapons is different from refining elixirs. The melting temperature of various mineral materials is much higher than that of medicinal materials, and the degree of solidification and fusion is also very difficult to control.
This makes it difficult for even the strongest weapon refiners to grasp the quality of weapons, and most of the time they can only rely on luck.
But if there are catalytic materials, melting and smelting will become quite easy.
Catalytic materials can melt various mineral materials faster and more thoroughly. They can also control the material ratio more accurately during smelting, greatly improving the success rate and the quality of weapons!
Among various catalytic materials, metallurgical sand is an excellent one, and the best metallurgical sand is the best among the best!
"If you get a piece of top-grade metallurgical sand, it will be easier to upgrade the Red Xuan Sword, and it will also be able to solidify the foundation and create a top-grade heavenly weapon!"
Su Mu's eyes flashed with a sharp light, he must get this top-quality metallurgical sand!
"It seems I can't shirk it." Su Mu said with a smile, took the invitation and put it in his arms.
The young man nodded with a smile, clasped his fists and left.
"Looking forward to your arrival."
"Master Chu?"
Gu Feng waited for Su Mu outside Danling Academy all night. Instead of seeing Su Mu come out, he saw the young man first. The moment he saw the young man, Gu Feng was stunned and couldn't help but look inside.
"Master Chu, when did you come?"
He waited at the entrance of Danling Academy all night, but he didn't see when the young man entered.
"Gu Feng, your fortune is good this time." The young man glanced at Gu Feng lightly and strode away.
Fateful? Gu Feng froze for a moment and hurriedly shouted: "Master Chu, please forgive me!"
He didn't know when he provoked the young man, but he didn't dare to ask, he could only plead guilty!
No matter what the century-old family, they still have to bow before King Cangzhao!
After the young man left, Gu Feng looked bitter. He suddenly realized that his life was very miserable. Not only did he offend Su Mu, but he also inexplicably offended King Cangzhao's grandson. Isn't this the end of the world?
King Cangzhao has lived for hundreds of years. Although he does not have many children, he has been passed down to the third generation.
That young man is Chu Feiyang, the grandson of King Cangzhao!
"What are you doing here?"
Su Mu walked out of the gate of Danling Academy and saw Gu Feng standing there with a bitter look on his face, and couldn't help but ask.
"Master Su." Gu Feng came back to his senses, shook his head with a wry smile, and did not say anything about Chu Feiyang, but took out the invitation.
"I've been waiting for a long time. I would like to invite you to attend the banquet of Prince Cangzhao's Palace."
Is it King Cangzhao’s banquet again? Su Mu raised his eyebrows slightly, then shook his head.
Not going? Gu Feng's eyes widened. You're not going to King Cangzhao's banquet? Are you okay? This is a once-in-a-lifetime opportunity. Don't you know how to seize it?
"Master Su, King Cangzhao is..." Gu Feng thought that Su Mu didn't know who King Cangzhao was, so he hurriedly explained.
"No need." Su Mu interrupted him and took out an identical invitation card from his arms.
"I already have it."
Gu Feng closed his mouth when he saw the invitation. He stared blankly at the two identical invitations. He looked up at Su Mu in disbelief and asked cautiously: "Did His Highness the First Prince give it to you?"
The only thing he could think of was the eldest prince. After all, not everyone could get the invitation from King Cangzhao.
Even King Cangzhao's invitation was given as promised, and he guessed right. The eldest prince's regard for Su Mu had reached an extremely high level.
"No." Su Mu shook his head. When he was about to explain, he realized that he didn't even know the name of the person.
No? Gu Feng frowned, why are there so many strange things today.
"Could it be Chu Feiyang?" An idea suddenly appeared in his mind, Gu Feng's eyes widened, and Su Mu was startled when he saw it.
When Su Mu saw Gu Feng startled, a black line appeared on his forehead. Are you okay?
"Mr. Su, is this the invitation sent to you by Chu Feiyang?" Gu Feng asked, swallowing his saliva.
"Chu Feiyang? Is he the one who just went out?" Su Mu asked, and Gu Feng nodded.
"It turns out his name is Chu Feiyang, and that's him.
"bass!"
Gu Feng took a step back suddenly and looked at Su Mu with a horrified face.
"The grandson of Prince Cangzhao actually sent you an invitation personally!?"
"This treatment..."
Even the eldest prince cannot enjoy this kind of treatment!
Gu Feng's whole body was in a mess. How strong must be Su Mu's background to be so favored by King Cangzhao!
Su Mu raised his eyebrows slightly in surprise, the grandson of King Cangzhao? No wonder he looked down on him when he was in the Tian family. With this background, he can really look down on most people.
"Wait a minute, you don't even know his name or who he is?" Gu Feng's eyes widened again. You don't even know his identity or name. How serious is this!
And it looks like Chu Feiyang is fawning over Su Mu!
"Wait a minute, is what Chu Feiyang said just now because of him?" Gu Feng suddenly remembered Chu Feiyang's warning when he left, and was speechless again!
He was almost certain that Chu Feiyang was trying to please Su Mu!
And all his discomfort came from Su Mu!
At this moment, Gu Feng couldn't help but feel a little lucky. Fortunately, he begged for mercy in time, otherwise he would definitely have died miserably!
Su Mu shook his head, turned around and left without explaining.
"Hey, wait for me!"
Su Mu regained his composure after Gu Feng was far away, and hurriedly chased after him.
"Master Su, are you going somewhere today?"
"No? Then I have a banquet tonight. Can I attend it?"
Su Mu paused, why was it all a banquet?
"Is there any benefit?" I changed my mind and didn't refuse directly. Anyway, I don't have anywhere to go now. If there is any benefit, then go there.
Uh... Gu Feng looked at Su Mu in shock. He didn't look like someone who was short of money. Why was he so greedy for money?
"There are no prizes at this banquet, but there are some jars of good wine."
"What kind of good wine?" Good wine will do. Although Su Mu is not an alcoholic, he will not refuse a good wine that can improve his cultivation.
"They are all made from hundreds of years old wine. Not only are they fragrant, but they are also strong enough!"
"The best among them is the strong fire. After taking a sip of the strong fire wine, your whole body will be burned, and you will enjoy the pain at the same time!" Gu Feng's mouth watered as he spoke.
The name of the wine is Fierce, it has been aged for three hundred years and is hard to find!
"Let's go, lead the way quickly!" Su Mu's eyes lit up after hearing this. This kind of good wine must not be missed.
Seeing Su Mu become so active all of a sudden, Gu Feng was stunned for a moment, then smiled and shook his head and chased after him. Sure enough, he was an alcoholic just like him.
"Don't worry, the banquet will start at night. How about we go to Happy Happy first?" Gu Feng caught up with Su Mu and winked.
"If you want to go, I'll find a place to stay first." Su Mu gave Gu Feng a roll of his eyes. He had no intention of doing that now. He just wanted to get the best metallurgical sand quickly and upgrade the Red Xuan Sword to the best heavenly weapon!
Gu Feng nodded helplessly, so he went to the nearest restaurant and settled down. After having a meal with Su Mu, they each took a room to rest.
In the room, Su Mu unloaded the baggage, and except for the materials for upgrading the Red Xuan Sword, everything else was put into the storage bag, leaving only a wooden box.
This wooden box is the third wooden box I got from Tianjia!
Su Mu took a deep breath and began to open the wooden box. Inside the wooden box, an ancient sheepskin scroll came into view.
I picked up the parchment and opened it. It was a map, and there was an obvious sword-shaped mark on the map!
"The map of the secret training realm of Wanjian Sect!"
Su Mu's excited hands trembled as he held the map. This map was the same as the one he got in Black Wind Village. It was a map to enter the secret realm of Wanjian Sect's experience!
Now that he has two maps in hand, it means that he has ordered two advanced swords like the Red Xuan Sword!
