According to what Chen Mou said on the road, each fortress checkpoint basically has its own smelting factory, which is used to process and smelt the transported iron ore to make weapons and armor, and Qingshui Pass is naturally no exception.

The smelter is located on the north side of the barracks in the city, and it is actually a cave built by hollowing out the interior of the mountain on one side.

In the huge caves, piles of coal fires burned under large furnaces, in which the iron ore melted into molten iron, and then soldiers poured the molten iron into the knife mold to form, then put it in water to soak it cold, and then began to hammer again and again, and finally made into a weapon.

Of course, Fang Ling would not come to the smelter for no reason, from the conversation with Chen Mou and Dong Canghai, he knew that this was a place of Longtan Tiger's Den, and Ma Kai would never be as respectful as he appeared to be, it was just an illusion that made people take it lightly.

When it comes to acting, I'm afraid no one can compare to the eunuchs in the palace. Each of them is a superb performer and pretender, and can change several faces in a flash, each one of which is convincing.

Growing up in such an environment, Fang Ling's kung fu is naturally much higher than that of ordinary people.

Although he had only been in contact with this Ma Kai for a short time, he was sure that this person was a cautious and careful person, good at power tricks, and he was probably very vicious, such a person would never give up the opportunity to befriend Empress Song, that is, he must be his enemy.

And, if you deal with yourself, you will kill yourself!

But the only thing Fang Ling didn't know was what kind of method Ma Kai would use to deal with himself, today his group entered Qingshui Pass in full view, Ma Kai would definitely not use the bright method, then only the dark one.

Although he didn't know what kind of secret method this secret was, Fang Ling realized that one thing he had to have to escape from Qingshui Pass was to prepare the conditions for escape.

Just those two thin horses and two broken carriages, even if they escaped from Qingshui Pass, what would they do on the long road to Stone City?

Therefore, since Ma Kai wants to kill himself, then why should he be merciful, this Qingshui Pass, which has sufficient materials, is an excellent place for Fang Ling to replenish supplies!

Fang Ling walked slowly in the smelter, and soon saw that there was a place where the smelted weapons were placed, including swords, swords, bows, axes, and shields, each of which contained hundreds of pieces.

Fang Ling casually picked up a knife and looked at it, the weight was not light at all, it weighed more than ten catties, it was heavy in his hand, and the blade was as smooth as a mirror, and the blade was extremely sharp.

Fang Ling couldn't help but praise secretly, he had seen the knife of the imperial guard, compared to this, it should be lighter and narrower, it was good-looking, but I am afraid that if you want to kill the enemy, this kind of knife is more lethal.

Ma Kai said on the side: "The iron ore in our Qingshui Pass is all high-grade iron ore directly transported from the iron mine three hundred miles away, and it takes five days to process and temper it through various procedures, before it can become this saber in the hands of His Highness." ”

"It sounds very good, but I don't know what the effect is?" Fang Ling said with a pretended surprise.

"Come on, show Your Highness what our weapons are at Qingshui Pass!" Ma Kai waved his hand.
