The purple-black armor has been completely shattered, but it can be seen that there should be some simple divine pattern assistance on this armor before.

Perhaps, it is the ice attribute god pattern, otherwise, it is really difficult to get in here.

Song Kai immediately put the Ten Thousand Years Xuanbing Heart into the storage ring.

After touching it for a while, both of his hands were about to freeze into popsicles.

It's dark inside the cave. However, the good thing is that the air is not so dirty.

Song Kai didn't dare to be careless this time, he took out the lighting Led panel, turned it on, and illuminated the entire cave very brightly.

Towards the cave, walk slowly, about fifty meters, and you will reach the end.

There were traces of the flame lizards on the ground, but there was nothing else.

Song Kai frowned, looking at the armor at the entrance of the cave, someone should have come in here, could it be that even the bones were eaten by the flame lizard.

The lighting panel was very bright, illuminating everything very clearly, and soon, Song Kai found that there were traces of the collapse of the mountain rocks on the cave wall on the left.

Walking over, Song Kai touched it on the left side, and sure enough, these stones collapsed later, but because the temperature was too high, even these stones slowly condensed into a large piece.

"There should be something in the stone. Song Kai looked left and right, then took out the gilded Lei Ri knife and dug a few times.

The stones have been glued together, it is not easy to dig up, Song Kai estimated the thickness of the stone wall, he simply put the things away, and then, with all his might, transformed the golden internal qi, and then used the space void step, "hum", Song Kai went directly through the wall in front of him.

The next moment, it was dark.

Song Kai turned on the light source and illuminated the place.

This is a stone cave of more than 20 square meters, in the cave, a corpse is lying by the wall, the whole corpse seems to be half burned, charred, emitting a stench.

There was a bunch of things on the ground, which should be a storage ring, because it couldn't withstand this high temperature for a long time, so it exploded directly.

Everything that could burn inside the storage ring had been reduced to ashes.

Song Kai turned on the light source and looked at the corpse.

Next to the corpse, there was a large stove, more than one person high, made of a kind of pitch-black metal, this stove, it looked a little peculiar, quite complicated.

"This is the Red Fire Armor Breaking Furnace," Song Kai breathed a sigh of relief, he bowed towards the corpse, "Dugu senior, trouble, I'll take your bones back for burial." ”

As he spoke, Song Kai was about to lift Dugu Lao Tie's corpse.

Raising his head, Song Kai was suddenly stunned, and he suddenly found that on the walls around him, there were a lot of dense words and many patterns.

Song Kai leaned over and looked carefully, on the wall, all the things written were about the method of forging, which was written by Dugu Lao Tie, before he died, all his experience and hard work, as well as all his feelings before death.

Perhaps because the parchment rolls were burned out, Dugu Soldering Iron chose to engrave words on the wall, every small character is vigorous and powerful, it can be seen that Dugu Lao Tie is a proficient calligrapher.

"The casting journey seems simple, but in fact it is extremely exquisite. Casting and alchemy, different ways and the same, fine study of the nature of the material, perceive the internal rules of the material, with the subtle flame, the auxiliary materials that complement each other, with the characteristics of the material, cast the equipment of the masterpiece......"

Song Kai looked at it and was fascinated.

As the final feeling before death, the whole text is hardly any nonsense.

Moreover, it can be seen that Dugu Lao Tie is much higher than the average caster. Most people just stay at the operation of the technique, such as how to control the temperature of the flame, how to melt the material, how to build a more stable model, and so on.

And Dugu Lao Tie goes directly into the essence, in his opinion, forging is actually the same as alchemy. Alchemy is to make all the attributes of the heavenly and earthly treasures finally integrate the essence, and in the process of refining, in order to improve the success rate, it is necessary to study the special attributes of each medicinal material.

In the same way, the same is true for forging, a truly skilled blacksmith is not only as simple as forging iron into iron knives, but also adding the right materials at the right time to make the most perfect alloy.

In addition, flame control, air control, and what kind of materials are suitable for what kind of weapons all need to be eradicated.

There are also a lot of elaborate methods of forging, and many of the illustrations on it are the most direct embodiment of Dugu Lao Tie's experience.

Song Kai kept nodding, feeling a lot in his heart, listening to the master's lecture before his death, it was different.

There are also ways to analyze the properties of materials, even if you get a material that you have not seen, you can also judge its properties and its endoplasm according to various methods.

Song Kai looked at it, and the whole person suddenly sat cross-legged on the ground, and he involuntarily entered a special state of mystery.

The words on the wall, like small tadpoles, all entered Song Kai's mind.

Then, it seemed that an old man suddenly appeared in front, he was hunched up, enduring the raging flames around him, standing there, giving Song Kai sentence by sentence, posture by posture, imparting the knowledge of casting, he said it quickly, but every sentence made Song Kai deeply agree, and let Song Kai's knowledge mind open one door after another.

I don't know how long it took, but suddenly, the old man fell to the ground all at once, and his whole body was on fire.

Song Kai also opened his eyes suddenly, and he looked around blankly.

The LED lights of the special solar cells made by the National Security Bureau have become dim at the moment.

This thing can last for thirty-six hours, is it that two days and one night have passed now?

Song Kai shook his head, there was a lot more forging knowledge in his head, and he still deeply understood that kind, even the most precious details of experience.

Song Kai sighed, he knelt down on one knee towards the corpse, "Master Dugu is above, I will bury you well, thank you Master for imparting knowledge." ”

Dugu's body was still there, already scorched by the flames, completely deformed.

At the end of his life, he knew that he could not escape, so he endured the burning of the flames and carved all his life's work on the stone wall!

Twenty years ago, the Flame Sacred Stone appeared, and this area was full of flames, and even stones could melt.

Dugu Lao Tie is fortunate to be already the fifth level of the Jindan Realm and has mastered the rules of water, otherwise, he will not be able to support it at all. There are rules of water, and it can resist the heat a little, but after all, it needs to consume spiritual power, and in the end, Dugu Lao Tie was still roasted alive.

Song Kai put Dugu Lao Tie's things into his storage ring. Then put his body in the storage ring.

After doing this, Song Kaicai moved his muscles.

Now, with the Red Fire Armor Breaking Furnace, and he has also gained almost all of Dugu Lao Tie's experience, after going back, it shouldn't be a problem to fuse the two materials.

Well, go back, the breath here is too poisonous.

Song Kai put away the light source and prepared to leave.

Inside the cave, it was pitch black again.

Just when Song Kai wanted to leave, suddenly, on the ground on the left, a very faint red light lit up.

After a while, the light dimmed again.

Then after three minutes, the light came back on, and the stone cave was all red.

"What's that?"

Song Kai walked over and looked towards the red light.

It turned out that there was a layer of Dali jade on the ground, and the red light was emitted from under the marble.

Song Kai was a little hesitant, and in the end, he picked up the gilded Lei Ri Knife, carrying the three elements of earth, fire and gold, and smashed it down on the marble with a bang.

This marble is quite large, but after so many years of roasting, it has become very fragile.

With a single knife, the marble cracked open a lot of cracks.

Song Kai looked at it and breathed a sigh of relief, it seemed that it didn't take a lot of effort, he raised the gilded Lei Ri knife in his hand again and slashed it down.

"Click" ......

This time, not only the Dali jade, but even the entire cave ground was cracked like a spider's web.

Song Kai simply got up and fell with a knife again.

"Boom...... Click......"

The entire floor of the cave was shattered......
