Du Sheng was slightly stunned, his expression was slightly embarrassed, and he immediately smiled apologetically at Chao Ye Tiantang.

Soon, Du Sheng walked up to Chu Yi and the others and said, "Everyone, please." ”

Since Master Du had issued an order to expel the guests, everyone naturally did not dare to continue to stay here, so they could only turn around and leave.

"Okay, I'm sorry to disturb Master Du, and when it's convenient for Master Du, the juniors will come to see you again." Chu Yi hugged his fist towards Master Du, and immediately followed the crowd and left the Fusheng Forge Workshop.

After leaving the Fusheng Forge Workshop, Chu Yi's cold eyes looked into the forge a few times, and the corners of his mouth rose slightly, outlining a cold smile.

Today, Chu Yi was not frustrated by Master Du's rejection, but was a little inexplicably excited.

That kid can casually take out a pound of thousand-year-old dark iron from his spatial ring, but I'm afraid that there are more thousand-year-old dark iron in his spatial ring!

………

At this moment, in the Fusheng Forge Workshop, Master Du took Ye Tiantang to the back hall, and the blue-haired woman was left in the front hall.

"You just said that the reward is a pound of thousand-year-old iron, but it counts." Master Du looked at Ye Tiantang and said.

"Nature." Ye Tiantang nodded with a smile.

"Junior, although the thousand-year-old dark iron is a treasure, it is just ...... Forging thousand-year-old dark iron requires different fire to refine, and ordinary fire is difficult to refine...... "Master Du has a deep meaning.

Since this son was able to take out the thousand-year-old black iron, he must have some materials for different fires on his body.

Once it can give birth to a different fire, the thousand-year-old dark iron will have its own value, otherwise, it will eventually be a ball of scrap iron.

"Junior, I can't hide it, these thousand-year-old black iron of yours are of no use to me...... I don't have the source of fire, and even if I get these thousand-year-old irons, I can't refine them. Master Du shook his head.

"So, what does the master mean?" Ye Tiantang asked.

"If you can find some fire sources of the different fires, you don't need a pound of thousand-year-old black iron, you only need to give me three taels as a reward, it is enough." Master Du said.

No matter how good the dark iron is, if it can't be refined, it's useless.

"What Master Du said, but this." As he spoke, Ye Tiantang's wrist flipped over, his palm was facing upward, and a golden flame appeared, fluttering in Ye Tiantang's palm like energy.

"Is this ......?!" Master Du stared at the golden flame in Ye Tiantang's palm, and his eyes flashed with disbelief and surprise.

Although Ye Tiantang did not have a different fire, the flame of her origin divine skill was not weaker than the different fire.

In the next second, Master Du's eyes showed an indescribable look of excitement.

"My flame is comparable to a different fire, and it can refine thousand-year-old dark iron." Ye Tiantang said with a smile.

"Not bad......" At this moment, Master Du's expression changed instantly when he looked at Ye Tiantang, as if he was looking at some kind of treasure.

"Master, the matter of building a blade ......" Ye Tiantang was stared at a little unnaturally by Master Du, as if he had become a high-quality meat.

"It's all a trivial matter, I want to ask, what's the name of the little brother?" Master Du said with a smile.

"Ye Chen." Ye Tiantang said.

"Okay, Brother Ye Chen...... This forging of blades is a trivial matter...... Brother Ye Chen, I want to cooperate with you......" Master Du's eyes flashed.

"Cooperation?" Ye Tiantang is inexplicable.

"Not bad!" Master Du nodded, with a mysterious expression: "In this continent, there is a dragon vein...... The land of the dragon vein gathers the richest aura of this continent...... In the dragon vein, there are countless rare treasures...... It's just that that dragon vein has a peerless gate, the Northern Underworld, and even the monopoly of the Guigu forces......"
