In the Rune Refiner skill improvement area of the Tower of Time, Zhang Tie was completely immersed in his own world.

In that barren area, Zhang Tie started from the skills of the apprentice craftsman, used a hands-on way to sort out and test the skills he had mastered, and then integrated what he had just absorbed into the hands-on operation.

Zhang Tie has never done such a thing, such a thing is both familiar and unfamiliar to Zhang Tie, if it is outside, Zhang Tie has no time to toss these seemingly naïve and time-wasting things, but in the Tower of Time, the most abundant thing is time, and Zhang Tie's main goal in the Tower of Time is to advance to the Divine Craftsman, which is a key step to realize the idea in Zhang Tie's heart, so he has a lot of time to do these things.

Zhang Tie completely regarded what he was doing as entertainment, and the entire rune refining skill improvement area was an entertainment area for Zhang Tie that belonged to him alone.

The simplest small brick kiln was done, and Zhang Tie still didn't stop.

Zhang Tie sharpened the edge of the stone in his hand on a stone by the stream, and then went to find two pieces of rotten wood and some small sticks.

Put those small wooden sticks on a flat stone and roll, from the running track of those small wooden rollers, you can easily choose the most reliable fire material, and then use the stone to sharpen a section of the wooden stick a little sharper, and the first tool for drilling wood for fire is made.

Although this link is simple, how to use the simplest method to select the most suitable for rubbing and rotating the fire-taking stick, and how to maintain the maximum frictional heat coefficient at the angle of the tip of the fire-taking stick when it is convenient to drill, these are all lessons that cannot be learned from books.

That's all there is to it. Then a piece of dry, decaying wood is smashed with a stone, and a pile of wood slag is ground on the stone. Then he ran to the stream and searched for it, picking up two brown stones by the stream. Rub the two brown stones in your hand, see sparks emerging from the stones, you can determine the sulfur content of these two stones, smash one of the two stones a little more, leaving a small handful of stone particles like fine sand, twist a little particle with two fingers and put it into the depression in a piece of rotten wood, and then sprinkle some wood residue, Zhang Tie began to drill wood to make fire.

Those stones with high sulfur content, when drilling wood for fire. It can increase the friction between the stick and the plank, so that the speed of the fire is twice the result with half the effort, and the ground wood chips and wood residue can be burned in the shortest possible time.

If he used his battle qi or used his knightly ability, Zhang Tie would be able to do these things easily, but at this time, with the ability of an ordinary craftsman apprentice, he would have different gains and pleasures in doing these things by himself.

In just a few minutes, Zhang Tie's wooden plank was smoking. The fine wood slag began to turn red and burn, and Zhang Tie added more fine wood slag and fine firewood to it, and it took a while. And the fire burned, and it was done.

Transfer the fire to a small brick kiln and pick up some firewood to add to it. After controlling the fire and heat in the small brick kiln, Zhang Tie ran to the stream. Dig a large dirt pit and start again and mud.

It is important to grasp the amount of water well when it is muddy. Excessive moisture, and the mud out is too thin, difficult to plastic, too little water, and the mud stickiness is not enough, easy to burst when firing, at the same time in the process of mud, to ensure that all the soil should be evenly and delicately blended together, no particles and bubbles are very important, the most important step, is also the last step, but also according to the nature of the soil, determine the size of the bricks, the size of the bricks and the characteristics of the soil, there is a correspondence relationship, This correspondence will determine the degree of refractory resistance and durability of the refractory bricks to be fired, if the size of the bricks does not match the soil properties, the fired bricks will have problems - although these are rough work, but in the rough work, there is also knowledge and learning.

After making mud, and then running over there to find a few pieces of wood and two stones, Zhang Tie made a simple manual brick-making tool, poked this tool into the pile of mud, and then picked it up and put it in Pingout, as soon as it was opened, a relatively regular rectangular mud brick was ready.

While making bricks with mud, Zhang Tie made tens of thousands of mud bricks in one go.

In the back, the mud bricks in front have almost dried in the shade, so Zhang Tie put the bricks that have dried in the shade into the brick kiln that has been completely formed to fire.

Anyway, he didn't feel hungry and thirsty in the Tower of Time, Zhang Tie was so focused that he forgot the passage of time......

The bricks were fired, and the first coke oven was built with the first batch of refractory bricks.

After setting up the coke oven, Zhang Tie went to dig coal again and burned coke with the excavated coal.

For a period of time, Zhang Tie has been busy.

Burning bricks, burning coke, making the simplest blower device, digging some iron ore with simple tools, and then building a smelting furnace with burnt refractory bricks and clay, putting in coke and iron ore, and igniting the ......

When Zhang Tie saw the red molten iron flowing out of the smelting furnace, Zhang Tie almost burst into tears, it was not easy to start from scratch.

Seeing the molten iron flowing out, Zhang Tie hurriedly guided the molten iron into the simple sand turning molds made by himself made of fired clay and stream sand.

Zhang Tie made a total of more than 30 molds, after pouring molten iron in these molds, as long as it is cooled and simply treated, Zhang Tie can get the first batch of iron tools, with this batch of iron tools, Zhang Tie's production efficiency can be increased many times, you can do more things, and so on, step by step, even Zhang Tie alone, can be smelted into steel with iron in this wilderness, block smelting, frying steel, filling steel, raw and cooked double iron steelmaking, crucible steelmaking, converter steelmaking, open-hearth steelmaking, one-step steelmaking, rune steelmaking...... Zhang Tie has mastered a lot of steelmaking methods.

With steel, there are more tools, and more things can be made, like steam engines, that can be made at your fingertips......

This process is the basic skill of the most basic craftsman apprentice of the rune refiner.

Zhang Tie tried it from scratch, and sure enough, he had different gains.

Wait until those molds have cooled down. After Zhang Tie processed more than 30 iron tools with the sand and gravel by the stream, he looked at the more than 30 iron tools placed in front of him. Zhang Tie finally let out a long sigh of satisfaction.

Zhang Tie took out a composite iron chisel for processing wood and flicked it with his fingers. The pleasant sound of metal from the iron chisel made Zhang Tie nod, the same is ironmaking, the quality of the iron smelted by different people is also different, his iron-making equipment this time, although it is the simplest, but in the process of smelting, Zhang Tie also used part of the steel frying technique, which further reduced the carbon content in this pig iron to a better level, so although these tools are iron tools. But its quality is definitely much better than that of ordinary iron tools, and it has a bit of steel.

When you get out of here, even if you reveal your identity as a rune refiner openly in the future, no one will doubt it anymore.

Zhang Tie thought secretly, and put down the tools in his hand with satisfaction, in the past, he was afraid that revealing the identity of the rune refiner would still arouse suspicion and criticism, for fear of being regarded as a demon, and from now on. He wouldn't have this worry, his rune refiner's skill also came from the Tower of Time, as for what the fruit of plundering he didn't know, what's wrong. Who dares to disagree, he can only say that his character is too good, and he is also a good reward. Whoever wants to be envious should go for it......

"Hahahaha......" Zhang Tie laughed alone, and finished laughing. Zhang Tie touched his face and muttered to himself. "I don't know how that woman is now, whether the injury is healed, or not, let's go and see for myself, I should also care about it, speaking of which, it seems that it has been fifteen days since I entered this rune refining skill improvement area......"

In the blink of an eye, Zhang Tie stayed in the rune refining skill improvement area for fifteen days, and in fifteen days, Zhang Tie started from scratch and made the first batch of iron tools in this wilderness, and it was not until this time that Zhang Tie felt a trace of fatigue.

Even if it is a knight, even if it is in the Tower of Time, if he does not sleep for fifteen consecutive days, it is against the law of existence of living things, and no matter how strong Zhang Tie is, he will naturally feel a little tired.

After washing his face by the stream and the dust accumulated over the past few days, Zhang Tie left the rune refining skill improvement area and walked out of the huge "crystal yurt".

As soon as he walked out of the "crystal yurt", Zhang Tie looked at the high platform.

Yan Feiqing was not cultivating there, if she was, there would be an obvious elemental reaction on that cultivation platform, and seeing that Yan Feiqing was not cultivating, Zhang Tie walked towards the crystal bed where she was.

Before he had to walk to the bed, Zhang Tie had just bypassed the cultivation platform and saw Yan Feiqing at a glance......

As soon as he saw Yan Feiqing's situation, Zhang Tie was startled, his whole body moved, and his speed suddenly increased by a hundred times, and in the blink of an eye, Zhang Tie rushed to the side of the bed.

Yan Feiqing was not sitting on the bed, but lying on the bed with her hair scattered and her eyes closed, there was a pool of blood on the bed, the blood stains flowed out from the wrist of Yan Feiqing's left hand, and Yan Feiqing's right hand was holding a bun on her head, judging from the wound on her wrist, it seemed that she pierced her arm with a bun, which caused the bleeding, and I don't know what kind of madness this woman has, she will actually harm herself here......

Zhang Tie hurriedly checked it, Yan Feiqing's hair bun still had blood stains, and the wound on her wrist was still bleeding continuously, which seemed to indicate that Yan Feiqing had just self-harmed, maybe less than an hour......

Zhang Tie almost did not hesitate to tear off one of his sleeves, tore the sleeve into strips of cloth, and helped Yan Feiqing bandage the wound on his hand.

When bandaging, wiping away those blood stains, Zhang Tie saw that the wound on Yan Feiqing's wrist, new and old, had more than one place, this was by no means the first time she had done such self-harm in the past few days, but she had done it all these days.

I don't know if this woman is crazy.

Yan Feiqing was originally cold, but the strange thing was that as soon as Zhang Tie picked up her hand and touched her, it was like pressing a switch, Yan Feiqing's cold body suddenly began to get hot like a boiling kettle......

Just when Zhang Tie was helping Yan Feiqing bandage her wounds, Yan Feiqing, who was in a coma, opened her eyes after a low groan and saw Zhang Tie who was tearing off her sleeves and bandaging her wrists.

"You give it to me...... Get lost...... Get out of the ......" Yan Feiqing's voice trembled and weakened, seeing Zhang Tie, for some reason, Yan Feiqing's eyes flashed a look of struggle.

"Ah, my aunt, don't think about it like that, even if I know that the guy who hung up outside has some emotional entanglements with you, but you don't have to come to such a show at this time, don't be martyred at this time, the two of us are now lonely men and widows, if you really can't think about anything, others know, and think that I am here What happened to you, I am the last person who can see a woman who wants to die or live in front of me......" Zhang Tie lowered his head and said while bandaging the wound on Yan Feiqing's hand, To be honest, Zhang Tie himself has a recovered body, so it is not a good idea for him to do this work, especially the old and new wounds on Yan Feiqing's wrist are not together, and it is still a little troublesome to deal with, "I see that your injuries don't seem to be healed now, if you want me to help, just ask, we are good people to do it to the end, send the Buddha to the west, and I still have a few potions with me......"

"You...... You let go of my hand...... Don't touch me......" In just a few seconds, Yan Feiqing's whole body was already flushed, and there was gasping in her voice, she wanted to withdraw her hand, but even if she was a phantasmagor knight, if she wanted to compare strength, she really couldn't compare to Zhang Tie, Zhang Tie took her hand, didn't move at all, just concentrated on bandaging.

"Don't move, it's fine, I don't do this kind of work often, strange, why are you so hot now, it's still cold just now......"

Zhang Tie only felt that Yan Feiqing's current state and voice were a little strange, but he didn't think much about it.

Yan Feiqing's hand couldn't be used, but the other hand directly hit Zhang Tie's shoulder, Zhang Tie didn't expect that Yan Feiqing, a woman, would actually do it at this time, the distance between the two sides was close, and without defense, she was directly slapped on the shoulder by Yan Feiqing and fell down at once......

Yan Feiqing's palm no longer had the power of the Phantom Knight, coupled with the thick flesh of Zhang Tie's skin, hitting Zhang Tie's shoulder, Zhang Tie just felt a little pain, and he was not really injured.

Zhang Tie's other hand pulled Yan Feiqing's wrist, Zhang Tie's fall directly ripped Yan Feiqing off the crystal bed, and with the power of Yan Feiqing's palm, Yan Feiqing, who was originally lying on the bed, rolled directly into Zhang Tie's arms......

Before he could feel the pain, Zhang Tie suddenly felt that the nephrite jade was warm and fragrant, Yan Feiqing's hot face was almost face-to-face with him, and one of his hands, coincidentally, was tightly held in a fat and soft place when he fell, while the other hand hugged Yan Feiqing's waist......

Zhang Tie originally wanted to get angry, but as soon as he felt the fat and soft mass he was holding in his hand, he habitually kneaded it, which was completely the habitual action that Zhang Tie developed when he was with his wife and concubine.

As soon as Zhang Tie moved, there was a wheezing sound in his ears, and this wheezing sound directly frightened Zhang Tie, and he immediately let go of his hand, "Ah, I'm sorry, I'm not ......"

Zhang Tie wanted to turn his head and explain to Yan Feiqing, but just as Yan Feiqing turned his head suddenly, the lips of the two people met in the air and kissed together......

The two sides are nose to nose at once, eye to eye, mouth to mouth......

This kiss, for Zhang Tie, only made Zhang Tie's eyes widen, like a thunderbolt from the sky, and his head went blank all of a sudden......

It's over, I just accidentally touched her, and now I accidentally kissed her, this woman won't kill me.

Thinking of Yan Feiqing's unpretentious temperament towards men and this woman's evaluation of herself when she first saw her, Zhang Tie was so careful that at this moment, his heart was beating thrash, and he could only pray that Yan Feiqing would not go crazy, otherwise the two sides would stay in this tower of time for sixty years, and the future would be sad.

What Zhang Tie didn't know was that this kiss was a thunderbolt from the sky to him, but for Yan Feiqing, it was the last match that lit a powder keg that was about to explode.

Just when Zhang Tie was at a loss, thinking that Yan Feiqing was going to chase after him, Yan Feiqing moved, but in an instant, the woman hugged Zhang Tie tightly, and then kissed Zhang Tie heavily on the lips......
