Seeing Leng Yi's smiling face, Cai Lun's heart was finally put in his stomach, and he said with a smile on his face:

"Creditor, please come here. Here's the first step, mash! Everything has to be mashed!"

"Part 2, Immersion Award ......"

"The third part, salvage large pieces, leaving only ......"

Cai Lun is the initiator of the whole process, and he is familiar with each step and explains it clearly.

Leng Yi saw that behind every process, there were people working.

It looks like Ten is very slow, and he looks very serious.

After all, it is a royal special, and it must be carefully crafted, and the slightest flaw may move the head.

There's nothing wrong with that.

"Well, I really have some ability. Let's go, I've got it all!"

Although he didn't hear the system's reminder, Leng Yi felt that he could make simple paper by doing it himself.

There was another skill he hadn't learned, and that was the sword he had promised to build.

Cai Lun knew that he still had something to teach, so he immediately led the way and came to a very remote house.

In front of a house, guarded by four guards with knives.

"Master Hou!"

Seeing Cai Lun arrive, he immediately bowed down and saluted, not daring to slack off in the slightest.

Although he saw Leng Yi behind him, he just didn't see it, pushed open the door, and let the two of them in.

"Lord Creditor, this is where I made swords and weapons, how about you take a look? It's already the best equipment in the world today!"

Entering it, Cai Lun seemed to come to life, his eyebrows and eyes were full of excited red, and he said loudly.

The big hand touched the iron platform next to it, touched the smelting furnace, and landed on the edge of the Qinshui pool next to it, as if it had not been built for a long time, with a full of memories.

Leng Yi swept the surrounding equipment, and I have to say that it was very clean, without the slightest smell of fireworks.

Moreover, there were no signs of smashing on the ingots.

That is, he has not used it since it was built.

Strange in my heart, I couldn't help asking:

"What's the situation? You've never used it, is it not good?"

He has seen the workshop of the cadre, which is completely different from this one, full of smelting atmosphere, and is the real everyone.

This is just a joke of the rich and noble.

There is not much expectation for Cai Lun's technology.

Of course, even if there is no sense of expectation, you must collect debts, and if there are fewer creditors, it will be a loss.

Anyway, there won't be much time to lose.

As if feeling Leng Yi's doubts, Cai Lun came back to his senses from his memories and said busily:

"Creditor, this is a place where I work hard, and I am reluctant to come on weekdays. Today, I'll make you a long sword from start to finish!"

As he spoke, he took off his brocade robe, took off his hat, and changed into a short placket.

Then he took a pair of deerskin gloves, took a few pieces of wood next to him, and put them in the stove.

The bellows were pulled a few times, and soon a fire broke out.

Even if the fire has just been lit, there is no smell of black smoke and miasma, and it still looks very clean.

"This is pine oil wood, which is particularly resistant to burning and is the best material for fire!"

"It's Ugin, copper, titanium...... To build weapons, you must not use a single material, the characteristics are too monotonous, either not sharp enough, or too hard. ”

"They melt at different times, so they should be divided into ......"

"Okay, now the step is to build the mold, and we use the ready-made one, which saves time. ”

"When the metal juice is poured out, it must be stirred well so that the alloy can be fused ......together"187

"The next step is the most critical step, tempered by a thousand tempers!"

Next, for three whole days, Cai Lun spent it here.

Hungry, thirsty, sleepy, never left.

The furnace never stopped burning, and the underwear on his body turned gray, with holes on it.

His hair is scattered, not like Hou Ye at all, but somewhat similar to a cadre.

"It turns out that I also have real skills, but I was wrong!"

Leng Yi saw everything in his eyes and said secretly.

Sometimes, things really can't be viewed from the side.

"Actually, this step, you can continue to beat, the longer the time, the more times you beat, the more different it will be when it comes out. ”

Cai Lun threw the iron embryo into the furnace again and said to Leng Yi.

Hearing this, Leng Yi had an idea in his heart, and suddenly said:

"You've been beating for three days and three nights, let me try!"

He wanted to try it and see if he could do it.

"Your Excellency, Creditor, why do you want to participate in such a lowly profession?

How could Cai Lun let him try, in case he hurt somewhere, he couldn't afford to eat it!

Leng Yi smiled and said:

"It's nothing, you can't see where I'm high, let me try. Don't worry, I won't hurt myself!"

He saw that the sword embryo was completely red, took the pliers, grabbed it, and placed it on the ingot.

Picking up the sledgehammer, he didn't feel the weight and smashed it down.

Cai Lun was dumbfounded in an instant, when he smashed the sword embryo, it was a little deformed, but in Leng Yi's hand, a large piece was instantly concave.

The power is beyond imagination.

And the speed is so fast that it keeps falling, and it's almost connected.

The sparks that should have flown out were all smashed back by him.

In a short period of time, the sword embryo was smashed more than 2,000 times, and it almost became the appearance of a long sword.

I smashed it for three days and three nights, and it was only a thousand times!

Immediately, Leng Yi watched it cool down and threw it into the furnace again.

"Oh my God, my lord, are you a Hercules?

Cai Lun was already incoherent, his eyes were so shocked that he didn't know what to say.

"Thousands of tempers, really extraordinary, I want to reach a hundred tempering, at least 100,000 beatings. What are the consequences?"

Leng Yi didn't know that he was like this, whether it was a good thing.

"You can refine it once a thousand times, and what comes out is definitely a sword! Terrifying, I don't know what kind of peerless sword will appear!"

Cai Lun's eyes were about to pop out, staring at the sword embryo in the furnace, looking forward to the moment when it took shape.

Leng Yi understands that in fact, the longer the hammering time, the higher the density, and the more the characteristics of the alloy can be brought into play.

"Ding, congratulations to the host for completing the task, Cai Lun's road to survival, obtaining 1300 creditor points, papermaking, and smelting swords!"

Just as he was thinking, a reminder from the system sounded in his mind.

In an instant, all the techniques for sharpening the sword, the tricks, the recipes for smelting metal, etc., all came to mind.

Some of the flaws that Cai Lun taught just now, and the tricks that were not spoken, were all compared.

After learning it, a smile naturally appeared on his face, looked at Cai Lun, and said:

"For your sake, I will tell you a life-threatening news. Now that the new emperor has ascended the throne, I am afraid that you will have to investigate the matter of framing Song Guifei back then, so imagine a way for yourself. ”

After saying that, he didn't take anything and went straight back to the real world.
