Wyvern thieves attacking Green Pine Valley? It seems that the situation should be very urgent, otherwise, the entourage would not have called Zhong Lei and Fang Tao over in such a hurry. I just don't know what the situation is in Aomatsu Valley now?

The news is still too closed, and no one in the ironworks can get out of the ironworks, except for the occasional news from the people who come to the ironworks, there is no other way to get the news inside and outside the Green Pine Valley.

Zhang Song sat in the shed, staring at the hot iron smelting field with empty eyes, but thinking about other things in his heart.

Outside the shed, some of the craftsmen in the ironworks were turning the smelted steel into weapons, which were mainly knives and spears, and occasionally some strange-shaped weapons, which Zhang Song had never heard of.

"Stones, how many people are there in the valley to carry weapons?" Zhang Song asked the craftsman who had scolded him.

"Not much, usually only two people." Stone replied.

"The two of them can't finish moving, right? So many weapons. ”

"This time I definitely won't be able to finish moving." Shi looked at the piles of weapons, "The number of weapons has increased, and no one has come to move them in the past two days, so they have accumulated even more." Heck, no matter what, it's their business anyway, we just need to build the weapon. ”

"That's not good, Green Pine Valley is now resisting the Wyvern Thieves, and they are in urgent need of weapons, and they are short of manpower, let me know when someone comes to carry them next time, and I will help them move over." Zhang Song confessed to the stone.

"Okay!" Stone replied loudly.

Zhang Song instructed Shi and the others to work harder in the past few days and try to build as many weapons as possible. Even if it was easier to build more weapons than before, Shi and the others happily agreed, and Zhang Song left.

A moment later, Zhang Song came to the coke oven.

The blacksmith was crouching in front of the coke oven, carefully tending to the stove.

"Iron Guy, have you been here all these days?" Zhang Song asked the iron guy in surprise.

"Yes, Engong, I will keep watch day and night." Seeing that it was Zhang Song coming, the iron guy got up and replied with a smile.

"You don't have to work so hard, you don't have to worry about it too much if it's already closed. You don't have to sleep here at night, you'll freeze. Zhang Song looked at the temporary shack built by the iron guy around the corner, and said with a sigh, "You are really a good craftsman!" ”

"Hehe, such an important thing, Engong, you give it to me, I have to take care of it." The iron guy was a little embarrassed, "Besides, I'm not afraid of the cold." ”

"Then it's up to you." Zhang Song saw that the iron guy insisted, and he didn't say more, "How is the situation with the furnace?" ”

"I think it's already burned, so I can pick it up and take a look." The iron guy said solemnly.

Zhang Song observed carefully, calculated the time, and nodded in agreement: "It's really time to take a look, you go and call a few people, bring a few buckets of water, and we'll take a look at it." ”

"Okay!" Seeing that Zhang Song agreed to open the furnace, the ironsmith happily agreed, and ran to the ironwork to call someone.

Zhang Song circled around the coking oven a few times, a little excited in his heart, he remembered that the coking time was about a week, and today happened to be the seventh day. An important indicator of whether the furnace can be grilled by soil coking is that the furnace no longer smokes. And the stove is no longer smoking, which means that it is time to grill the stove.

In a short time the blacksmith came with the craftsmen who had built the stove, each carrying a barrel in his hand.

"Engong, I didn't dare to call more people, so I called these people, mainly because I was afraid that there would be too many people." The iron guy explained to Zhang Song.

"It's enough to have these people, you're doing a good job!" Zhang Song is very satisfied with the iron guy, and the iron guy is very thoughtful.

"So what now?" Listening to Zhang Song's appreciation, the iron guy asked with a slightly red face.

"Come, do as I say." Zhang Song poked the air hole open with iron tongs, "Pour water into it from here." ”

The iron man asked Zhang Song to stand aside, and he and several craftsmen poured water into the furnace under Zhang Song's guidance until Zhang Song called a stop.

When the stove was almost cooled, Zhang Song commanded the iron man and a few others to pick up the stove.

It didn't take long to pick up the stove, but Zhang Song felt that it was very long.

When the stove is opened, the contents of the stove are revealed. It is a substance of similar shape and size as coal, but the color is much lighter, and most of it has small pores.

"Hey, it's really not burned clean." The iron guy was very surprised and said, "Is this what you mean by coke?" Eun Gong. ”

Zhang Song was also dumbfounded when he looked at this pile of substances, because he had never seen coke, but he knew that high-temperature closed distillation was the method of coking, but he didn't know how to judge the success of coking.

Looking at the pile of coal-like but different substances in front of him, Zhang Song smiled bitterly and said, "I don't know, I haven't seen coke, I've just heard of it." ”

"What should I do then, I don't know if it's useful?" One of the craftsmen whispered, a little disappointed in his tone.

The blacksmith and several other craftsmen all looked at Zhang Song, waiting for Zhang Song's instructions.

"In this way, you put this color and this small pora together, and store the others ......separately," Zhang Song said after carefully observing the shape of those substances.

Orr, Iron Guy and a few others were divided into categories, and most of them had stomatae, and only a small part of the others.

"Is the iron-smelting task completed today?" Zhang Song asked.

"It should have been done." The Iron Guy replied.

"Then you put this pile of coke in the iron smelting furnace, and then smelt another furnace of steel, and see how it works." Zhang Song said to the iron striker, "If it is better than coal, it is coke, and if it is not good to use coal, it is not coke." ”

"Okay!" The iron guy quickly understood what Zhang Song said, and said happily, "Then are we still coking?" ”

"Let's stop refining for the time being, let's see if these are coke." Zhang Song replied, "A few of you will transport this coke to the iron smelting yard. ”

When several other craftsmen were carrying coke, Zhang Song told the ironman some basic principles of coking that he knew, and asked the ironman to think of more ways to make good coke.

Seeing that Zhang Song trusted him so much, the iron guy was very excited, and he gave Zhang Song a big salute.

"Thank you Engong for trusting me so much, I will do my best to fulfill Engong's entrustment!"

"You don't have to be so polite, if you have any difficulties in the future, just come to me, and I will help solve them."

A trace of hesitation flashed on the iron man's excited face, and he stopped talking.

"What's wrong? Are there difficulties right now? Let's hear it. Zhang Song was a little surprised.

"There is no difficulty." After a few hesitations, the iron man still said, "I just hope that Engong will allow my son to stop working in iron smelting in the future." ”

Zhang Song was stunned for a moment, and then immediately reacted again, this is not the era of "learning mathematics, physics and chemistry well, and not being afraid to go all over the world", this is a feudal society with all evils, or a feudal society with deep remnants of slavery.

In this society, the social status of artisans is extremely low, and ironsmelters are no exception. Moreover, this profession of artisan is hereditary, and whenever possible, craftsmen do not want their descendants to become artisans.

Zhang Song looked carefully at the iron guy without saying a word. The iron guy was stared at by Zhang Song, but considering the future of his descendants, he still mustered up the courage, forced his composure, and did not let go.

"How do you think I have what it takes to help your son get out of the craftsman trade?" Zhang Song suddenly smiled and asked the iron guy.

The iron guy breathed a sigh of relief, and he replied respectfully: "I just think that Engong is an extraordinary person, and he must make contributions in the future." ”

"You're not afraid of the non-human?"

"No, I believe in Eun Gong's ability." The Iron Guy said firmly.

Zhang Song didn't make a sound, just looked at the iron guy and pondered. The iron guy didn't dare to disturb Zhang Song, and waited quietly for Zhang Song, feeling uneasy, for fear that Zhang Song would not agree to his request.

"Okay, I promise you, I'm afraid that you don't want your son to leave the craftsman industry at that time." Just when the iron guy became more and more uneasy, Zhang Song agreed to the iron man's request.

The iron guy finally put his heart into his stomach, but he was a little puzzled, for some reason Zhang Song would conclude that he didn't want his son to leave the craftsman industry. However, he still didn't ask much after all, and since Zhang Song had agreed to his request, he didn't want to do anything more.

"Zhang Jun, Zhang Jun, someone is here in the valley!" One of the craftsmen who had left just now returned and said loudly to Zhang Song.

"Someone's coming?" Zhang Song stood up, "Okay, I'll go over right away." ”

Zhang Song wanted to take the opportunity to help the people carry the weapons to take a walk in the Green Pine Valley and inquire about the news in order to decide his next move.

Hurriedly returning to the shed of the iron-smelting yard, Zhang Song found that only one person had come to the valley, and the man was restless in the shed, seemingly anxious.

"I'm sorry you've been waiting, we'll start moving the weapon right away." As soon as Zhang Song arrived, he said to the man, "You only have one person, it is definitely not enough, and it will take a few more people to finish moving." Stone, you and I will help carry the weapons into the valley. ”

"Okay!" Stone happily agreed.

The person who came from the valley was very confused when he heard Zhang Song's words, and he looked at Zhang Song in confusion. It wasn't until Zhang Song, together with the stone, began to tie the weapon that had been built with ropes, that the man reacted, and he hurriedly stopped Zhang Song's behavior.

"Oh, Zhang Jun, you're mistaken, I'm not here to carry weapons!"

"You're not here to carry weapons, so what are you doing here?" Zhang Song asked in surprise.

"When Guli was resisting the attack of the Flying Dragon Thieves, someone was injured, and this time I came to ask Zhang Jun to go and heal the wounded." The man said anxiously, "The situation is urgent, please Zhang Jun prepare as soon as possible and go with me." ”

"I see." Zhang Song suddenly realized, "Then you wait, I'll go clean up, prepare the medicine and equipment, and I'll go with you right away." ”

"Please also ask Zhang Jun as soon as possible!" That's humane.

Zhang Song hurriedly returned to his residence, prepared the medicine he had collected before, and prepared some other things, and returned to the iron-smelting shed.

As soon as Zhang Song returned to the iron-smelting shed, the man hurried to the hinterland of Qingsong Valley.
