R&D department, smelting workshop, hammer jingling.

Tang Xiaoyu was bare-chested, wielding a heavy iron hammer, sweating to make a heavy iron weapon. Unlike mass-produced fine iron weapons, each heavy iron weapon not only requires precious fire stones as fuel, but also requires a master forger like him to devote himself to using his special abilities.

"Master Tang." Jin Yan stepped in.

"Mr. Jin, you're back." Tang Xiaoyu replied casually, still concentrating on the weapon, and didn't look back, "You wait a minute, this thing will be finished soon." ”

"Okay." Jin Yan casually sat on a nearby bench.

After about ten minutes, Tang Xiaoyu quenched the heavy iron weapon and threw it on the cutting board, only then did he turn around.

"Mr. Jin went out this time, Ye Li's kid, is he still powerful?" Tang Xiaoyu was most concerned about Ye Li.

"It's not bad, just take him to see the world. He is getting better and better, and he speaks a lot more fluently. Jin Yan said. After experiencing Muhuatang's training and courses, Ye Li has indeed made rapid progress, not only is his strength the strongest among the new generation, but he is also a lot more sensible.

"That's good, that's good." Tang Xiaoyu was very pleased. After Ye Li was his old friend, he was able to make some progress, which made him very happy. He was willing to follow Jin Yan and join Jin Yuan, and Ye Li was also the most important reason.

"Master Tang, you can help me take a look at this thing." Jin Yan took out the meteor hammer obtained from the Xuanwu envoy.

"Darksteel." Tang Xiaoyu recognized it after just looking at it.

"This is the Wangxian Continent, the weapon of the Xuanwu envoy of the Blood Yin Clan." Jin Yan simply said his experience in the Tianhua Ghost Cave.

"From the perspective of conventional immortal weapon casting, Xuantie is indeed extremely rare." Tang Xiaoyu said, "No matter how strong the casting materials are, Star Iron, Soul Iron, Ze Iron and the like, they are all hard to find." ”

"Master Tang, you say, what kind of mystery is the Tianhua Ghost Cave, why doesn't it have a time limit for disappearing like other boundary points, but can exist for a long time?" Jin Yan asked, "This should be the only boundary point I know that will not disappear." Even the bronze statue can't do such an effect, and it doesn't work from time to time. ”

The more Tang Xiaoyu listened, the more solemn his face became.

"Mr. Jin, I'm a rough man, I turned out to follow Emperor Ling and the master of Lixuan Hall to work in the craftsman hall to build weapons." He said slowly, "I'm not a knowledgeable person like Mr. Sun. This is the kind of boundary point that can connect the two worlds and will not disappear...... I've never heard of it. ”
