"This one is saltpeter, this one is malachite. ／／／…… And this one is...... This is ......" Su Yao looked at the transparent crystal in front of him and suddenly didn't know anything.

"Fluorite." Bonus told him helplessly. "You don't even know all the basic ores now, let alone make iron. Unless you memorize them all, and then know exactly what's inside these stones, then you'll be able to get started. Hua Hong grabbed a stone on the table and rubbed it left and right, "Wucheng is a place rich in minerals, and swordsmiths often have to go out to find materials for sword casting by themselves, so the requirements for the ore course are also very high. If you don't even know about open source, you won't have to live in this place. ”

"If I go any further, I'm afraid I'll become an old scholar who knows astronomy and geography," Su Yao held his forehead with a headache, "No matter how you look at it, it looks like a rough guy, where did you come from so many doorways." "I'm afraid he's going to fall now, and he can still come up with a mixed name and go into the city, and now it seems that climbing the wall is more reliable than this, if the exam doesn't pass, then most of the month's efforts will be in vain.

"You'd better kill the idea of climbing the wall in your head first, or you'll die on the first exam while thinking about how to climb the wall and how to take the exam." Hua Hong glanced at someone lying on the table, how to look at it before, he was such a spirited person, and when he was entangled in his studies, he became so decadent, and he praised him for having a good memory, and he never forgot what he saw at a glance, but now he thinks that if he doesn't know how to use knowledge, those things that are stuffed into his brain are pure bullshit, and it is just a waste of memory capacity.

"Honestly, you don't really want to stay in this place for more than half a year, and then slowly surround the city from the outside and burrow into it like a moth, right??" Su Yao already knew the result of Hua Hong's inquiry about that fragment, if the people outside didn't know, the people inside wouldn't necessarily know, anyway, the person who shot last time would definitely not let go of himself so easily, even if he didn't check him, he would come to the door again, Su Yao wasn't worried at all, but compared to his character of being at ease, Hua Hong is completely the kind of person who takes precautions, what to turn passive into active, knowing that the other side can not slack off, and tactically it is already completely polarized. Su Yao doesn't care much about this, mainly because his status is not equal at all now, and he can be regarded as a bonus comrade-in-arms, this grass-guy has no consciousness to be on an equal footing with him, and he can't wait to wear a rope on his nose to lead him, in the face of this hegemonic comrade-in-arms, Su Yao has no way at all, the current situation is that the bonus is left, if Su Yao dares to go to the right, he will be turned into a traitor and traitor, I really don't know when I fell to this point.

"I'll do it again, if you really can't pass the exam by then, you just wait to climb the wall with me." Su Yao threw away the last sentence sullenly, sat up straight and continued to read.

"Do you really climb the wall??" Hua Hong looked at Su Yao and raised her eyebrows, quite disdainful, do you think that wall is so easy to climb?? "If you're bored, you can go to the open space two blocks ahead of us and take a look, it seems that there has been a heated sword-forging contest recently, and you can also learn a lot by the way."

"Look at them striking iron, what's so beautiful," Su Yao is really more and more repulsed by the swordsmith industry, now there is no stove and no utensils, and when the time comes, he doesn't know if he will make jokes on the spot, anyway, he feels hopeless.

"Then you are wrong, sword forging is not only about iron," Hua Hong glanced at Su Yao meaningfully, "Sword forger and blacksmith are completely different concepts, people also want to try it, but they have no talent in this area." ”

"I'll go, I'll go." really thought of a play, Su Yao finally compromised, pushed the things on the table to the side, and walked outside.

"Don't be lazy!!" At the end of the bonus, he also gave a word of advice in the back, which made Su Yao extremely depressed.

Seeing Su Yao leave, the smile on Hua Hong's face gradually faded, and he closed the book in his hand and stood up.

Su Yao followed the direction indicated by Hua Hong and came to the place where the so-called sword-forging competition was held. It was just an empty piece of sand, uninhabited by the surrounding area, and it was usually a place for middle-aged women to dry their clothes, but now it was effectively used. But unexpectedly, when Su Yao arrived there, there were already a lot of people outside, and at a glance, he knew that he was watching the game, Su Yao couldn't help but be curious, and drilled inside, only to see that a large area was consciously given up by the masses in the center of the open space, and there were three or four young people standing side by side, all of them were the kind of sturdy young people that Su Yao imagined, and at this moment the group was in full swing under the gaze of the crowd to forge their own swords.

Unexpectedly, Su Yao didn't see the so-called big furnace and all kinds of hammers as he imagined. Those people stood in the center empty-handed, their arms half-raised, and Su Yao squinted his eyes and continued to observe.

At this glance, I found that a stream of air was slowly rising in the palms of their hands, and those people were concentrating on that air flow at the moment, and it could be seen that everyone was very serious and struggling, and their brains were full of sweat.

What is this doing?? Su Yao inexplicably watched the group of people maintain this action motionlessly, it seems that this has nothing to do with sword casting, right? ?

After waiting for a while, those people still maintained their initial movements, and the condensation speed of the breath in their hands was very slow, Su Yao couldn't help but be curious, so he turned around and casually pulled someone and asked, "Sir, what are they doing here?" "Practicing qigong?? That's not going to happen, is it? Does the boiler still rely on qigong to exert force? ?

"Gather qi, summon fire, only those who summon fire can be upgraded to a D-level swordsmith." That person didn't even look at Su Yao, and replied casually.

Summoning fire?? Su Yao was frightened by this answer, is this okay?? Just by virtue of its own breath? That's too godly, isn't it? It's almost time to catch up with their own god fragments.

"Soon, soon......" The man behind him continued to stare at the people intently after finishing speaking. It looked like something was about to happen.
