In the early morning, the sun is rising and the sun is shining.

The entrance to the yard of the blacksmith's house in Koishi Village.

"Sister-in-law, is Brother Zhao here?" Lin Chenxing held his sword in his left hand, and gently knocked on the open wooden door with his right hand, heading towards the courtyard.

Hearing this, the middle-aged woman who was packing up some dried vegetables in the courtyard turned around and saw Lin Chenxing, raised her eyebrows, and said enthusiastically: "It's Brother Chen, come in, come in!" ”

As she spoke, the woman had already greeted her, and she didn't care about the long sword in Lin Chenxing's hand.

"Sit in the house first, your brother Zhao is in the backyard, I'll call him!"

Lin Chenxing hurriedly said: "No, no, sister-in-law, you are busy, I'll just go find Brother Zhao myself!" With that, he walked in the direction of the backyard.

Seeing this, the woman no longer insisted, anyway, since Lin Chenxing was able to get out of bed and move, the most familiar place in the village is probably this courtyard.

The woman knew how much the arrival of this young man had brought to the man of his family, and naturally she would not stop it.

Lin Chenxing came to the backyard with a familiar car, and saw a burly middle-aged man, scratching his somewhat scattered black hair, standing in front of a sink with a depressed face.

"Brother Zhao!"

When the middle-aged man heard this, he raised his head in surprise, came to Lin Chenxing in three or two steps, and patted him on the shoulder with his big hand, "Haha, little brother Chen, I was just going to look for you!" Come on, come on, you can help me see, this ground is cracking again! ”

As he spoke, Lin Chenxing was pulled by Zhao Tiezhu to the side of the sink.

Glancing at a hunting knife next to the sink, Lin Chenxing knew why Zhao Tiezhu was so sad early in the morning.

It all started a month ago.

At that time, after lying in bed for a month, he felt that his body was about to rust. After Li Lao nodded and said that he could get out of bed and move, he couldn't wait to walk out of Li Lao's courtyard and wander around the village.

As a result, after many years of forging swords, he was attracted by the sound of clanging iron somewhere in the village, and finally came to Zhao Tiezhu's house.

The Iron Pillar Man is good, and he also wants to know more about this world, and the two have a common word.

This meeting naturally started chatting, and after coming and going, they slowly became acquainted.

Lin Chenxing was pleasantly surprised to find that Zhao Tiezhu's manual forging level was no worse than that of some skilled workers and technicians in Lanxing.

He guessed that the overall level of hand-forging in this world was likely to be better than Lan Xing in some aspects, after all, Zhao Tiezhu was just a blacksmith in a small village.

However, slowly, Lin Chenxing also found that Zhao Tiezhu didn't seem to pay much attention to the follow-up heat treatment process of forgings.

In other words, he did not master the heat treatment technology commensurate with his level of forging skills.

On Bluestar, people with a little forging knowledge know that the last key step in determining the final comprehensive performance of forgings is the heat treatment process.

The combination of various heat treatment processes can greatly stimulate the potential of the material itself, so that the final performance of the forging can be improved to a higher level.

However, after many observations, Lin Chenxing found that in this world, at least here in Zhao Tiezhu, there is only one kind of heat treatment process that can be called quenching.

And it's the simplest and roughest quenching!

Whether it is the knives handled by Zhao Tiezhu or the farm tools, there are only two ways to deal with them after forging. One is to throw it on the ground; The other is to throw it into the water.

When Lin Chenxing completed a kitchen knife that had been treated with a simplified version of the earth-covered burning blade technique under Zhao Tiezhu's slightly skeptical gaze, and used it to easily knock out a gap in the hunting knife made by Zhao Tiezhu, this upright man was completely impressed by Lin Chenxing.

Because he knew very well in his heart that the kitchen knife that Lin Chenxing used to cover the soil and burn the blade was slightly inferior to the hunting knife in terms of forging quality alone.

The only difference that makes the final result different is the seemingly simple overlay burning blade.

Afterwards, Lin Chenxing taught Zhao Tiezhu the technique of covering the earth and burning the blade without reservation, and this was the source of the Tiezhu family's warmth and friendliness towards him.

The topic turned back to the backyard of Zhao Tiezhu's house in the morning light.

"You're not sure how thick the overburden is, here, here, and here...... These places are thicker. Near the cutting edge, the thickness should be slowly reduced, and the thickness of the covering layer must not change too quickly. Otherwise, it is easy to crack at the cutting edge! Lin Chenxing's eyes were sharp, and he saw the problem at a glance, and a few words of guidance were even more to the point.

When Zhao Tiezhu heard this, he habitually scratched his head and said, "There are so many Taoist ...... here."

Then he said a little embarrassedly: "Brother Chen, you sit down for a while, and I'll try again." I don't believe it yet......"

Knowing that his hands were itching, Lin Chenxing didn't wait for him to finish, so he said, "You're busy with you, don't worry about me, I'll use your dinner guy." ”

"Hehe, that's a good feeling. Brother Chen, you are casual, casual, hehe......" As he spoke, the upright man picked up a pre-made knife blank and began to try again.

After seeing the magic of the earth-covered blade, he could never forget this technique, and he couldn't sleep well for a day before he fully mastered it.

Lin Chenxing didn't care, and took the long sword in his hand and entered the hut next to him.

"It's time for you to get the hilt of your sword to strike......"

"Hahaha, Brother Chen, look at it, how about my knife?"

About an hour later, Zhao Tiezhu's ecstatic laughter came behind Lin Chenxing with his rapid and powerful footsteps.

At this time, Lin Chenxing was tying the last knot of the cloth strip in his hand.

The hilt of the sword had just been matched, and the long sword that had been opened was tightly wound with a layer of coarse cloth, and no trace was exposed.

Turning around and taking the hunting knife in Zhao Tiezhu's hand, Lin Chenxing looked at it carefully, and then handed it back.

Zhao Tiezhu was like a young schoolboy at this time, looking at Lin Chenxing expectantly, hoping to be recognized by him.

Without deliberately whetting his appetite, Lin Chenxing said directly: "This handle is not bad, but if you look at the lines on the blade, it is obvious that there are more places covered by the soil, and the thickness of the last part of the covering layer is slightly thicker." Therefore, this knife has more than enough toughness and lack of sharpness, so it can only be regarded as a mid-to-upper product. But it's still a lot better than your previous rough and simple methods. ”

Hearing Lin Chenxing's comment in one breath, Zhao Tiezhu was full of joy: "Hehe, I'm already very satisfied." As long as it can be made, hahaha......"

"Let's go, it's almost noon, I'll let your sister-in-law sauce elbow, let's have a few sips, hahaha......"

Zhao Tiezhu laughed, and without waiting for Lin Chenxing to answer, he pulled him and strode towards the front yard.

Lin Chenxing was pulled by him, shook his head with a wry smile, and didn't think about breaking free.

Compared with strength alone, he is far worse than this burly man who has been fighting iron for half his life at this time.

After a full meal, Lin Chenxing came out of Zhao Tiezhu's house and prepared to go back to Li's hometown.

Now that he is well recovered, he is ready to prepare, and it is time to go out and see the world well.

As soon as he turned the corner, Lin Chenxing's eyes froze.

I saw that next to the locust tree at the entrance of Li's family's courtyard, three majestic jujube red horses were standing quietly, and a man in a black suit was standing straight at the door.

There was a long knife hanging from the waist of the man in the power suit, a real war knife, not those hunting knives made by Zhao Tiezhu.

"These people ......" Seeing this, Lin Chenxing seemed to be thoughtful.
