"Xingchen Tie?" Tang Feng looked happy.

Xingchen iron is also a type of ore, but in terms of quality and preciousness, it is much more valuable than those ordinary iron ingots and steel ingots. Although it can't be compared with black iron and flying crystal, it is also a rare mineral.

The Stellar Iron itself emits the kind of light that shines like a sky full of stars, so it was named this one.

Tang Feng didn't expect that in Tianxiu's room, there was actually a large piece of unused Xingchen Iron Ore, and he didn't know who found it in the first place, and then left it here. It was a windfall.

Looking at Tang Feng's appearance, how could Siniang and Tang Feixiao not know what his idea was?

Uncle Xiao slapped himself: "Look at my mouth!"

Originally, the two of them worked hard for two whole days, and finally finished forging all the metal ingots, only thinking that they were finally going to call it a day, but they didn't expect that now they had found Xingchen Iron again, don't think about it, Feng Shao must want to build this Xingchen Iron again.

Uncle Xiao was annoyed, and he knew that he would say that this was an ordinary ore.

Tang Feng smiled: "Siniang, I'm going to bother you again." ”

Qin Siniang glared at him charmingly, and then reached out and grabbed this basin-sized piece of raw ore, and the ore weighing at least hundreds of catties was as light as nothing in Siniang's hands.

The white scorching qi flashed with a white light, and the raw ore melted in Siniang's hand in an instant, and the juice was tumbling, and impurities were constantly spilling on the ground.

This piece of Xingchen Iron is just raw ore, and it has not been processed in any way, so it can be said that most of it is impurities, and only a small part can be used.

It can be seen that it is more difficult for Siniang to melt this piece of Xingchen Iron than it is to smelt those ordinary iron ingots and steel ingots, because when she smelts those metal ingots, only a little light comes out of her hand, which is enough to completely melt, but now, the white scorching qi in her hand is a foot high, and the smelting speed of Xingchen Iron is still a little slow.

Gradually, there were more and more impurities on the ground, and the star iron in Siniang's hand became smaller and smaller.

It took half a burnt of incense to clean up all the impurities, and Siniang put away the white scorching qi, and the original basin-sized Xingchen iron ore in her hand was only a round ball the size of a palm.

Although there is only so much, this is the essence of the essence of the whole piece of raw ore, which was compressed by Siniang with Gangqi, and the impurities have basically been removed.

After Siniang put it in the water to cool it, and when she fished it out again, Siniang couldn't help but look confused: "This is really beautiful!"

This piece of star iron is like a shrunken sky at this moment, and under the firmament, hundreds of millions of stars are twinkling, among which one is the brightest and the brightest, showing a semicircular shape, just like the moon guarded by the stars. Even though the room was pitch black, this piece of starry iron emitted a dense light.

"Feng Shao, what do you want to forge this into?" Tang Fei asked with a smile, "This thing is too small, if it is refined into a sword, the materials may not be enough, do you want to refine it into a dagger?"

Tang Feng shook his head, and with a touch of his wrist, the broken star appeared on the palm of his hand: "Young Master, I already have a heavenly soldier dagger, what else do you need a dagger for?"

"You don't want to refine hidden weapons again, do you? It's too wasteful to use such good materials to refine hidden weapons. Uncle Xiao shouted for Xingchen Tie, and looked at Tang Feng up and down, left and right, he wanted to see where Tang Feng hid the Heavenly Soldier dagger just now.

"A secret weapon, of course. Tang Feng smiled, "It may seem like a waste to you, but in my opinion, it is definitely the maximum use." ”

Tang Feng hurriedly ran over and lit the candles in this room, and then drew a set of patterns on the ground with the hot sun.

This set of patterns is composed of four parts, and Tang Feng is meticulous in his depictions, his movements are extremely gentle, and the paintings are quite delicate.

Siniang and Tang Feixiao leaned their heads over, and the more they looked at them, the more confused they became, because none of these four patterns looked like a hidden weapon.

"What kind of secret weapon is this?" asked Uncle Xiao suspiciously.

Tang Feng smiled and said nothing, the patterns that Tang Feng gave to Siniang before did not hide any secrets, and they belonged to the most ordinary secret weapons, so even if they were known, it was nothing.

But this is one of the secrets that Tang Feng doesn't want to expose, even if Uncle Xiao and Siniang are trustworthy people, Tang Feng doesn't want them to know. It's not that Tang Feng cherishes himself, nor does he not treat them as his own, but there are some things that are best known only by himself.

This is a hidden weapon designed by Tang Feng himself, with a hidden mechanism. The four parts can be combined or separated. When the heart wheel encounters resistance, such as attacking the enemy, the speed will increase suddenly, forming a cutting effect on the enemy, and at the same time, the built-in flying needle will be triggered, shooting the enemy at the closest distance.

Moreover, if you add an imperceptible and extremely tough silk thread to the heart chakra, the heart chakra can be retracted, and you can also use your fingers to control the direction of its attack after flying out.

With Tang Feixiao and Siniang's eyesight, even if you can see that these four parts can be combined, you can't see the mystery inside.

"Siniang, use this piece of Xingchen Iron to refine two sets of these things for me, and help me cut out a piece of Xingchen Iron and refine two five-zhang long iron wires. Tang Feng pointed to the pattern on the ground and said, "There can't be the slightest mistake between the size of the refining and the one I draw." ”

Because it has to be combined, if there is a slight mistake, then it cannot be combined.

Siniang nodded solemnly, carefully examined the four patterns for a long time, and then began to move.

Siniang has also accumulated some experience in the past two days, and it can be said that when she was refining what Tang Feng needed, she was also exercising her control over Gang Qi.

At the rise of the scorching sun, Siniang cut a whole piece of Xingchen Iron into ten pieces in an instant.

Two of them are used to refine silk threads, which is very simple and easy. The remaining eight pieces are used to refine the heart chakra.

The progress of things was beyond Tang Feng's expectations, because the secret weapon was divided into four parts, so each part was not very complicated, Siniang refined it very easily, and the only thing that needed to be paid attention to was to control the size.

It took an hour before and after, and Siniang had already completed it.

Tang Fei smiled: "There's nothing you want our husband and wife to help with now, right?"

Tang Feng smiled while playing with the parts of the heart wheel: "No, you go back to accompany Mengmeng, tomorrow we will go up to Quting Mountain." ”

"But it tired the old lady to death. Qin Siniang said.
