It took six hours for Jiang Fan to finally smelt the hammer thoroughly.

As a result, after the last rune was melted, it was originally only the diameter of the bowl mouth, and the length was only equivalent to a hammer head more than two feet long, and it swelled several times in a flash!

Boom!

Although Jiang Fan desperately tried his best to control it with his divine thoughts, when the hammer metal smashed on the ground, there was still a loud bang, stirring up a gust of wind!

MD！

Jiang Fan sweated wildly in his heart, this weight definitely exceeded ten tons!

That is, the construction quality of this hotel is excellent enough, and he has just added several reinforcement circles, so there are no big fluctuations, and even the sound is not felt outside.

"This should be the Dark Iron of the Earth!"

After some research, Jiang Fan came to this conclusion.

The so-called geocentric dark iron is a special metal mined deep into the center of the earth. Because of the high temperature and high pressure environment there, the metal molecules are extremely tight, so that the physical and chemical properties are different from the outside world, so the name of the outside world cannot be strictly applied to them.

Knock knock knock......

There was a knock on the door.

Jiang Fan was startled, at this time, the geocentric dark iron was still piled on the ground, and he couldn't clean it up at all!

He hurriedly squirted out the Dulong cone, and only after being completely prepared did he ask, "Who?"

"Brother Jiang, it's me!"

Miao Miao's voice came from outside.

Jiang Fan breathed a sigh of relief: "What's the matter?"

"I just heard some movement, did you get it?"

"Well, I'm practicing, it's okay!"

"Well, something to call me!"

Miao Miao was very sensible and knew that Jiang Fan was doing something unspeakable, so she immediately returned outside and acted as a protector for Jiang Fan.

Jiang Fan in the house knew that he had to dispose of this pile of geocentric iron, otherwise it would be a big deal once it was exposed!

If you want to deal with it, it will naturally be to refine the same treasure again, but what do you want to refine?

Now he doesn't have a baking furnace, and he hasn't entered the realm of transforming gods, so he can't send out the true fire of samadhi, and the magic weapon he refines can't be too advanced, so this time it's only a temporary refining, and when he returns to the secret realm or advanced to the god realm, he has to refine it again.

Jiang Fan has seen a lot of magic weapon refining methods in both the Mai Divine Technique and the secret realm, especially the research experience of Yang Xiantong in the secret realm, which touched Jiang Fan a lot.

Looking at this pile of black earth-centered Xuaniron, Jiang Fan suddenly thought of the smelted Fantian Seal that he saw in the secret realm......

Fantianyin!

One of the top treasures in the legendary god world!

It is said that the Yuan Shi Tianzun used half of the Buzhou Mountain as the material to refine, the size is arbitrary, and the magic is incomparable. At first, it was given to Guangchengzi, and later it was given to his disciple Yin Jiao by Guangchengzi. He originally wanted Yin Jiao to go to Xiqi to assist Jiang Ziya against the Shang Dynasty, but Yin Jiao was changed by Shen Gongbao's words, and instead went to the Shang Dynasty, and used the Fantian seal to smash the Xiqi soldiers and generals, and in the end, Guangchengzi invited the Five Elements and Five Square Banners and Taiji Diagram to control Yin Jiao.

Although Fantianyin did not help Yin Jiao smash Xiqi, such a record is enough to be proud of!

According to the statement in the list of gods, the Fantian seal can be big or small, almost invisible when it is small, but it can cover the sky and the sun when it is big!

Yin Jiao was trapped by the Five Elements and Five Flags in the end, and escaped to the north and encountered the mountain blocking the way, and directly smashed out a passage with Fantian Seal, which shows how terrible Fantian Seal is!

"If I also refine a Fantian Seal......

Jiang Fan's saliva flowed out.

Although he was referring to his own skills and materials, it would be a joke to refine the real Fantian Seal, but even if it was a fake!

You must know that men have a desire to destroy in their bones, and the greatest use of Fantianyin is destruction, and it is simply smashed until it is smashed!

It couldn't be cooler!

"It's so decided, refine a Fantian seal!"

As soon as he thought of it, Jiang Fan immediately crossed his knees on the ground, and first went through the refining techniques recorded by Yang Xiantong in his mind.

Compared with other magic weapons, the refining method of Fantian Seal is relatively simple, because this magic weapon does not have those messy functions, it is just one word - heavy!

Therefore, the biggest requirement of Fantianyin is not the refining technique, but the material!

If Jiang Fan also had Buzhou Mountain as a material, plus the corresponding mana support, he would also be able to refine a genuine Fantian seal, of course he didn't have it, so everything was YY.

"Hurry!"

As his handprint changed, a mouthful of True Yuan sprayed on the pile of black earth-centered Xuaniron, and it immediately merged into it.

Jiang Fan continued to spew out mouthfuls of True Yuan in order to let this pile of Xuaniron finally fuse with his True Yuan attributes, and then continued to refine the metal with Heavenly Dao True Fire, trying to drive out the impurities in it.

In fact, this step was completely redundant, because the original refiner's technique was even more clever than him, and he had already completely expelled the impurities in it.

After a full twelve hours of this, the earth-centered dark iron was finally completely melted by Jiang Fan and turned into a red ball of molten iron!

This pile of ten tons of molten iron floated in the room, occupying almost most of the space, and the high temperature made it difficult for ordinary people to gain a foothold.

Fortunately, Jiang Fan's continuous reinforcement of the formation type caused no major changes in the environment in the house, but if it continued, he didn't dare to guarantee what would happen.

"Almost, let's start taking shape!"

After finishing the preliminary work, Jiang Fan began to follow the steps of refining the Fantian Seal, imprinting the Dharma Seals one by one on the Earth's Core Dark Iron.

According to the experience left by Yang Xiantong, if you want to refine the Fantian seal, two kinds of magic seals are the most important, one is the law seal of any size, and the other is the law seal that controls the weight!

The size of the matter is not to mention, after all, no one will carry a piece of metal the size of a car to fight. And the magic seal that controls the weight is also the key, even if the maximum weight of this Fantian seal is about ten tons, but if the magic circle is powerful enough, it can even double or even triple its own weight!

Think about the weight of thirty tons roaring down, and there is only one word for that feeling - cool!

If there's an enemy down there, that's even better!

Another ten hours passed, and the floating pile of large pieces of metal had been compressed to the size of a watermelon, square and slightly trapezoidal, with a small Taishan-shaped seal on it, and countless runes shining all around it, like eyes flashing non-stop.

"There's one final step, and that's the key!"

Jiang Fan's expression became extremely solemn, and the speed of the seal in his hand became slower and slower, as if he was holding a mountain!

The last Dharma seal is imprinted, as long as it is imprinted, the Fantian seal will be completely successful!
