When the iron knife opened a wall, there was a boiling heat wave from inside, and its temperature was so high that Tang Tiandu was sweating profusely before, and he felt like he was almost ignited.

"Is this the fire in it? How could it be such a high temperature", Tang Tian wiped his sweat and said, the temperature here is not much deeper than the place where the Flame Mountain is thirty miles deep, the most important thing is that this is not really in the flames, but the heat emitted by the flames.

Tie Dao glanced at Tang Tian with disdain and said, "Hou Ye is also a college student, haven't you studied geography?" You don't know how hot the temperature is in the center of the earth? That's just the temperature of the earth's core before the end of the world, in the last days, the temperature of the core of the earth is to give birth to all the creatures on the earth of such a large size, how can its temperature not be high, you imagine, guide the temperature of the center of the earth to the ground, how high is the temperature? Although this is not yet a direct core temperature".

Well, Tang Tian was despised again, but he was speechless, but his heart was full of fear, this iron knife was really guiding the temperature of the center of the earth to the ground, so ...... his strength?

"Let's go, after entering, I will close the door, and I can't come out until your equipment is built, it can't be interrupted during this time, don't think about it, the temperature inside is very high, no matter how much I can't stand it, I can endure it", Tie Dao looked at Tang Tian with bad intentions, and strode in.

Tang Tian was a little strange in his heart, not that he was surprised that the iron knife did not shed a drop of sweat in such a high temperature, but he saw a hint of schadenfreude in the eyes of the iron knife, Tang Tian estimated that he was probably tricked this time.

Once inside, the space inside has been distorted by the intense heat, like a bottle of colorful and turbid water, and it is impossible to see things from a distance of several meters. The intuition is full of hot pain, and the high temperature burns unbearably.

"I said, Brother Tie, I haven't seen the fire yet, how high is the temperature?" Tang Tian followed the footsteps of the iron knife and asked a little speechlessly. is also wearing a weather suit, not afraid of fire and water, otherwise this time he will run naked again.

"Based on your calculations, the temperature around here is about 3,000 degrees," Iron Knife said lightly.

Tang Tian had a feeling that he wanted to collapse, what was the melting point of molten iron? What is the melting point of just now? If it weren't for the weather suit on his body, I'm afraid that the temperature of the periphery alone would have melted him, right?

"When you arrive, you just stand here, and if you go any further, you may not be able to stand it." I don't know how far I went, anyway, Tang Tian felt that he might be burned at any time, and suddenly heard the sound of an iron knife.

When I looked up, I saw the distorted air of my underwear, but I became very calm, and I could see everything clearly, here, it was a huge underground space. I cut myself on the edge of a protruding stone, and one step further is the bottomless abyss.

In front of Tang Tian. It was an abyss thousands of meters wide, and the ground was fiery red, as if it was magma, but it didn't seem to be, and the rolling heat wave passed up from below, and then the center of the abyss. It was a black stone platform, covered with intricate dense patterns, a diameter of 100 meters wide, floating above the abyss.

In the middle of the stone platform, there is a hole with a diameter of one meter. There was a pillar of fire in the middle of the cavern, which was colorful in color, but it was bound by some chain-like thing that roamed around the periphery, and it was not able to spread.

Tang Tian was surprised to find that under the stone platform, there were rolling red flames rising like an inverted tornado and converging into the hole under the stone platform, and finally formed a colorful flame above the stone platform.

"Master Hou, don't guess, just look at it, the temperature of your location is the lowest place here, and it was only because the earth fire was not bound by the formation under the stone platform that it was so high before, okay, I won't tell you more, I'm going to start, you just watch there", the iron knife had already gone to the top of the stone platform, and he didn't turn around and said to himself.

Tang Tian chose to shut up, because he knew that if the iron knife was unhappy and threw himself into the fiery abyss below, he would definitely not have the slightest chance of survival.

I saw the iron knife on the stone platform, and threw out all the equipment materials that Tang Tian had given him before, and after flipping through and picking and choosing, he took out a red dagger, but it was broken, it was a broken legendary equipment, he shook his head in his hand and muttered something, and threw it into the colorful flames in the stone platform.

Tang Tian is not a blacksmith, so he doesn't know what the casting material of the legendary equipment is, but since it is the legendary equipment, the melting point of the material is definitely not something he can imagine, but after the iron knife threw the red dagger into the colorful flames, it suddenly softened visibly to the naked eye, and Zuihou completely melted, turning into a fiery liquid thing, and the process did not take more than three minutes!

"How hot is this special rainbow flame? Melted the legendary dagger so quickly"? Tang Tian thought speechlessly in his heart.

After the dagger melted, the iron knife just waved his hand simply, and suddenly the colorful flames separated into wisps of red liquid that enveloped them, and even divided into wisps into the red liquid, and it was visible to the naked eye that the melted dagger was decreasing, and some things that Tang Tian thought were waste slag were separated.

"Is this the extraction of impurities"? Tang Tian asked himself in wonder.

The whole passage lasted less than a minute, and the red liquid no longer decreased in size, but turned into a black eye, and only a finger remained!

At this time, the iron knife nodded in satisfaction, and the only remaining black object was raised into flames, put it aside, and then picked up a mottled black war sword, pouted and waved his hand and threw it into the colorful flames.

This time, Tang Tian heard his self-talk clearly, and only listened to the iron knife say: "Good materials have been ruined, isn't it better if there are some essence materials not to be cast into a flying knife, Fei wants to add some garbage materials to make a battle sword, and also legendary equipment, I bah."

Hearing the muttering of the iron knife, Tang Tian understood, what he meant was that the really useful part of the so-called legendary equipment was only a little bit, and the rest was all garbage materials......

Tang Tian was a little crazy, and some were looking forward to it, wanting to see the peerless divine weapon mentioned in the mouth of the iron knife as soon as possible!

The whole process is very boring, that is, it keeps throwing pieces of equipment into the colorful flames to melt and purify, and Zuihou only has a little useful thing left, but the iron knife is only operating those broken legendary equipment.

Among them, some equipment was only purified to get a point the size of a needle tip, and some were purified to get a point the size of a finger, Tang Tian didn't know what the standard of the iron knife was, what to refine, anyway, he just thought it seemed quite simple.

When all the broken equipment was purified, a total of basketball-sized things were obtained, colorful, and I don't know what they were, and they were put aside by the iron knife.

Tang Tian roughly estimated this process, and it lasted at least a day.

At this time, Iron Dao picked up a handful of Haode legendary equipment, and threw it into the colorful flames without any consideration, but the difference was that when the equipment was in, it did not melt quickly, but the chain-like things around the flames became so small that they were invisible to the naked eye in the blink of an eye, and entered the equipment.

Tang Tian's ears faintly heard the sound of something shattering, and then those chain-like things appeared again, but the equipment in the colorful flames was different from before, and it was also beginning to melt.

"Isn't the finished haode equipment different from the broken one? Need to break it in order to melt? Probably so", Tang Tian thought uncertainly in his heart, the final reason was because he was not professional enough.

It takes a little longer to smelt these complete legendary equipment, a third longer than the broken equipment, and piece by piece the equipment is thrown into the flames, smelted and purified to obtain what the Zuihou Iron Knife thinks is useful.

The iron shattered teeth obtained from Sasaki of the Sun Kingdom were thrown in, the fiery red broadsword obtained by Yang Tianlin was thrown in, and the well moon obtained from the iron-blooded general Zhou Shan was thrown in......

Watching the legendary equipment being melted down and getting a little bit of something, Tang Tian's heart twitched, you know, these things are all people snatching their heads when they go outside, and in the eyes of the iron knife, they are no different from garbage.

Zuihou's piece of equipment is a blood-drinking knife that has always accompanied Tang Tian, even in such a hot environment, it still exudes a cold chill, and it is the only thing that makes the iron knife frown slightly.

His fingers slammed on the blade of the Blood Drinking Maniac Knife, and Zuihou still threw it into the colorful flames, but the Blood Drinking Mania Knife kept trembling and buzzing as if it didn't want to be smelted like this.

With a wave of the iron knife's hand, the chain-like thing around the flame suddenly entered the flames, but it did not enter the inside of the Blood Drink Crazy Knife, but instead tied up the Blood Drink Crazy Knife like a bondage.

To Tang Tian's surprise, near the place where the flames shot on the stone platform, an inscription lit up, and zuihou shot out golden silk threads into the inside of the Blood Drink Crazy Knife, and it was only at this time that the Blood Drink Crazy Knife quieted down, and then, it began to melt gradually......

"Am I going to learn blacksmithing too? Otherwise, it's not a matter if you don't understand anything like this", Tang Tian groaned helplessly in his heart, but he quickly dispelled such thoughts...... (To be continued......)
