On Ningle's workbench, sawdust flies everywhere.

Soon, several cavities were carved out in the middle of the honey iron core. But judging from the shape of the casting mold, everyone was a little puzzled.

"This is not a sword, not a sword, a gun or a stick...... It's not long enough, huh?"

"Not really. Wouldn't the blank cast from such a mold be too fine if it was used to make a gun stick?"

"I guess it's a part that needs to be spliced together. ”

"If you look at it like this, it may be a halberd, or a whip and a piece of armor. ”

"It's a short staff. Shan Qi recalled that Hu Guang, who was cut into two pieces by the broken yao that night, and gave the correct solution.

Ren nodded in agreement and said, "This guy is obsessed." ”

"And what's going on with this gloomy wood?"

Shan Hao saw Ning Le put down the core of the honey iron tree, turned his head and began to chisel the gloomy wood, and asked in a somewhat puzzled whisper: "Isn't that used to make some small machines, and it can also be used as a casting mold?"

"I've heard of this girl before. This gloomy wood is very resistant to high temperatures, and there are many naturally formed cavities on it, which can be used as a mold for small parts with a little carving. ”

Ren recalled: "The parts cast in this way tend to have a natural and smooth curvature, and the armor made is less ingenious. It's just that such parts definitely can't be made in batches, and the versatility is naturally poor. ”

"And that kind of statement?"

Shan Hao was surprised: "I know a lot." Before that, Xiao Lele still asked you to read those basic books......?

"Can you not mention this black history?" Ren was a little tired.

She has a lot of things to hearsay, but she also doesn't know a lot of common sense of Yanshu!

The two casting molds were chiseled, and Ning Le rushed to the furnace non-stop, and it happened that Pingcang was also burned brightly. Ning Le carefully observed for a moment, and immediately increased the temperature of the furnace by increasing the charcoal blast again. Pingcang quickly melted, and the molten iron flowed into the special crucible that had been prepared for a long time.

"It turned out to be a heated melting forging method. "Shan Hao's eyes lit up.

This time, it was Ren's turn to be at a loss: "What is the heating melting forging method?"

Shan Hao explained: "Xiao Lele took advantage of the high melting point of calcined refined iron, first calcined Pingcang at a relatively low temperature, initially removed most of the impurities, and then melted it by suddenly heating up, so that the obtained refined iron liquid can be more uniform and stable. The difficulty of this method is that it needs to be finely controlled, and the failure rate is quite high. However, once you do it, you can save a lot of time in tempering the blank. ”

"So did he succeed?" Ren was overjoyed.

Shan Hao nodded: "But he has been chiseling and casting the mold just now, how can he achieve fine temperature control?"

"Maybe only he knows. Ren looked at Ning Le, who had already begun to cast, and gave up thinking very simply, "He can always surprise others. ”

"Young Castle Master!" Unexpectedly, at this moment, Ning Le suddenly shouted.

Shan Qi, who had been watching him silently, was also stunned: "?"

Ning Le was casting the blank with a plier in one hand, but with the other hand, he waved straight at Shan Qi, signaling him to step forward.

Shan Qi immediately came to him without saying a word: "What?"

"Ask you something. Ning Le stared at the casting mold on the workbench and slowly cast, but asked quietly, "You...... How many years have you been single?"

Shan Qi was stunned again, and said warily: "Dog abuse?"

"Do you want to ask if you're a boy or not...... Ning Le leaned in and whispered a few words in Shan Qi's ear.

"What?!" Shan Qi's voice instantly rose an octave, and he looked at Ning Le in surprise.

"If you understand, hurry up, the master is waiting to use it here. Ning Le waved his hand and sent Shan Qi away.

Shan Qi: "......"

"Don't bother. Ning Le urged, "There are so many people present, you are the ones who can be trusted." Could it be that you want the master to go to the two of them?"

Shan Qi turned around and ran, pushing aside the crowd and disappearing outside the workshop door in an instant.

Everyone looked at each other.

Which one is this singing?

After the casting was completed, Ning Le ignored the small parts in the gloomy wood, but directly split the core of the honey iron tree, took out the two blanks that had not been completely cooled, one thick and one thin, and clamped the thin one onto the big anvil.

"It's finally time to start tempering. ”

Ren subconsciously glanced out the window and found that the scorching sun was in the sky, and it was past noon. On the other side, Shan Qing had already completed the repeated quenching of the blank and was preparing to start making the magnetic traction core of the Yan Armor.

The progress gap between the two is really too big.

Is it too late? Ren and Shan Hao were secretly asking in their hearts, but they couldn't ask.

Bell –

With a crisp sound, Ning Le smashed the first hammer at the blank on the anvil table.

Clang!

Ning Le opened and closed widely, and quickly smashed the second hammer.

Bell –

"Huh?" Shan Hao frowned slightly.

"What's wrong?" Ren asked nervously.

Shan Hao pointed at Ning Le, his lips opened slightly, and his eyes became more and more round.

"This, tearing the sky with seven hammers?!"

"How is that possible? How could he tear the Seven Hammers of the Heavens?"

"Who taught him this?"

“...... Wait, this is the third hammer. ”

Clang!

"First, the fourth hammer?"

Bell –

"Fifth Hammer!"

Just when the audience was holding their breath, Ning Le did not knock down the sixth hammer, but took a breath and moved the blank on the anvil.

Almost everyone breathed a sigh of relief.

Shan Qing couldn't hold back after all, stopped the process in his hand, pointed at Ning Le and asked, "Where did you steal this Sky Tearing Seven Hammers?!"

Ning Le ignored him at all, but followed his own rhythm and struck the first of the seven hammers of the Sky Tearing Hammer again.

"This is the unique technique of the Heavenly Forging Castle?" Ren took a look at the clue and asked in a low voice.

Shan nodded deliciously: "The Seven Hammers of Tearing the Sky are the ancestral tempering methods of my Shan family. The seven hammers are penetrated in one go, and the more you go to the back, the greater the power. If you can cast the seventh hammer in one breath, you can contain the power of gods and men, and it is known that the power can tear the sky. It's just that every time this hammer is struck, the energy and spirit power consumption will be more than double that of the previous hammer. Now in the entire Heavenly Forging Castle, there are only a few people who can knock out this seventh hammer. ”

Ren nodded slowly, rolled his eyes, and said no more.

It's not that she wasn't curious about why Ning Le would tear the Seven Hammers of the Heavens, but now was naturally not the time to dwell on these.

Shan Hao also looked playful, but he was silent.

Ning Le maintained his unhurried rhythm, and every time he hit the fifth hammer of tearing the sky, he would move the blank and start again from the first hammer. His movements were repetitive and mechanical, but each hammer seemed to hit the hearts of all the children of the single family present.

Seven hammers to tear the sky, five hammers in one go, this is the goal of most of them!

Soon, the first blank on the anvil table turned into a smooth and round thin stick under Ning Le's repeated beatings. And at one end of the thin stick, there is also a three-edged gun head.

Seeing this, Shan Qi frowned slightly.

Not a short staff?

"It's ...... Guns?" Ren wondered, "but isn't the barrel too thin?" ”

"I guess it's a spear. Shan Hao was also a little uncertain, "Short spear?"

Everyone was discussing what Ning Le had created, but Shan Qi had been staring at Ning Le silently, and his face became a little ugly.

When everyone else was surprised why Ning Le would tear the Seven Hammers of the Heavens, he found another important point - Ning Le had not re-forged even once in the whole process of tempering this blank!

Just looking at the blank is still red and shiny, Shan Qi knows that it is still hot!
