In fact, there is no problem with the bellows, but the iron guy was nervous when he was installed, and it was not installed in place, and now after Zhang Song reinstalled, the bellows can be used.

Zhang Song only made a small modification to the bellows, and the bellows originally used in the ironworks were a very primitive bellows, that is, single-acting piston bellows, and Zhang Song only changed him to a double-acting piston bellows.

Although it is only a small change, the air intake volume has been doubled, which can provide more oxygen for iron smelting.

After installing the bellows, the iron guy asked people to pull the bellows and try it, which was more laborious than before, but the air volume was much larger.

Seeing the iron ore in the furnace melt much faster than before, the eyes of the craftsmen came back to life.

"Very good, very good, everyone be diligent, this mission should be able to be completed." The iron guy was in good spirits all of a sudden.

"I'm sorry, Zhang Jun, I blame you!" The craftsman who had accused Zhang Song ran over to salute and apologize.

Zhang Song waved his hand to show forgiveness for him.

People in a desperate situation will do all kinds of incredible things, Zhang Song had seen many in his previous life, and even sheep could turn into demons, not to mention that the craftsman only accused Zhang Song and did not attack Zhang Song.

"As long as we can complete the task, they will not be able to embarrass us in the future." The iron guy said happily to Zhang Song.

Zhang Song smiled and did not answer. If he wants to be embarrassed, unless Zhang Song is dead, he will find all kinds of ways to make it difficult.

Zhang Song looked at the sky and silently calculated the time in his heart, Yu Xinzhi said that he would come over today, this should be the time to come. He patted the iron guy on the shoulder, got up and walked to the iron-smelting pool, where the molten iron had already begun to tumble.

Zhang Song picked up a place, sat down, and looked around.

The iron guy looked at Zhang Song's actions, his smile disappeared, and there was more incomprehensible flavor in his eyes.

"Damn it!" The iron guy scolded viciously.

Zhang Song didn't wait long, and the person in his heart appeared in the iron-smelting yard. This time, Yu Xinzhi and Chen Jia did not appear, and what appeared was the entourage of the two of them.

The two attendants visited the iron-smelting yard and found Zhang Song's face gloomy when they found him sitting by the pool where the molten iron was boiling, but they didn't dare to say anything to Zhang Song. He just scolded the craftsmen in the ironworks and threatened them to tie Zhang Song up when he fell asleep at night, otherwise he would be punished.

"Get out!"

Seeing the frightened appearance of the craftsmen, Zhang Song suddenly felt a little annoyed in his heart, he stood up abruptly and shouted at the two attendants.

The entourage was furious and walked towards Zhang Song.

"If you're not afraid of death, come here." Zhang Song said arrogantly.

Maybe it was because he thought of Zhang Song's ruthlessness, maybe it was because Yu Xinzhi or Chen Jia had an explanation when he came, in short, after Zhang Song said that sentence arrogantly, the two entourages calmed down and stopped walking forward.

"Wait! We will be back tomorrow! ”

The two attendants shouted and left.

After those entourages left, Zhang Song's mood was not better, no matter who it was, someone would harass him every day, and his mood must not be happy.

We must stop the harassment of Yu Xinzhi and others, Zhang Song thought.

But is there any way to stop the harassment of Yu Xinzhi, Chen Jia and others? Zhang Song thought about it for a long time, but he didn't come up with any good ideas.

"Oh......"

From the other side of the iron-smelting furnace came the cheers of the craftsmen.

Zhang Song stood up and turned his head to see that the craftsmen in the iron-smelting yard were cheering, and one of them was running towards Zhang Song.

"Zhang Jun, our iron-smelting speed is twice as fast as before, we can complete the task, even if we don't work overtime, we can complete the task." The craftsman's face flushed with joy.

"Oh, is it? That's good. Let's go, I'll go and have a look. Zhang Song knew that the use of production tools could improve production efficiency, but he was a little surprised that improving a bellows could improve such a high efficiency.

The craftsmen all looked at the arriving Zhang Song with warm and grateful eyes. Zhang Song smiled at the craftsmen in a friendly manner, checked the iron-smelting furnace and bellows, and was very happy, and the efficiency had indeed improved a lot.

"Even with two days left, we were able to complete the task." The iron guy happily said to Zhang Song, "This is really a great joy." If Zhou Mingshu knew, I don't know how happy he would be. ”

Zhang Song's heart moved, and he asked, "Does Qingsong Valley need steel very much?" ”

"Yes, very much, and that's why they came up with that vicious way to push us." The iron guy is angry and sad.

"I see that most of the farming tools in the Green Pine Valley are made of iron, so why do you need so much steel?"

"It was mainly used to make weapons, not agricultural tools. It is said that during this time, Qingsong Valley often clashed with other forces, and Qingsong Valley had many defeats, and Zhou Mingshu was injured in the conflict some time ago, so Qingsong Valley urgently needed weapons to improve his strength. ”

"I see." Zhang Song looked at the two bellows in front of the iron-smelting furnace and pondered.

The ironsmith didn't dare to disturb Zhang Song's thinking, and while urging the other craftsmen to work hard, he observed the movement at the entrance of the iron-smelting yard.

"Who usually reports something in the iron-smelting yard, and to whom?" Zhang Song suddenly asked the iron guy, "Is it you?" ”

The iron guy nodded and said, "It's me who went to report to my wife." ”

Zhang Song smiled and said: "The efficiency of iron smelting has improved, this is a great joy, you can also report it later, and tell them that from today onwards, the iron smelting yard can double the amount of iron produced." ”

"No, no." The Iron Guy shook his head desperately, "If that's the case, we'll have to work overtime like before." ”

"Oh, don't shake your head in a hurry, listen to me!" Zhang Song said loudly to the iron guy.

The iron guy quieted down and saw what Zhang Song had to say. Zhang Song attached himself to the iron man's ear and whispered all his plans.

"Will it work?" After hearing this, the iron guy was skeptical.

"Surely, you'll have to do me a favor." Zhang Song's tone was very certain.

"Then why don't you go yourself? I'm afraid I can't tell you clearly. "The iron guy is still a little worried.

"I can't go by myself, I left the ironworks without permission, I'm afraid that before I speak, I won't die." Zhang Songdao.

In fact, Zhang Song was still sure to persuade Zhou Mingshu, but Zhang Song was worried that he would be arrested by Yu Xinzhi, Chen Jia and others before he saw Zhou Mingshu.

"Okay, then I'll report it." The iron guy finally agreed.

"Remember to report to Zhou Mingshu first, if you don't meet Zhou Mingshu, don't tell others, come back directly." When the iron guy was leaving, Zhang Song patiently explained.

"Got it." Hit the iron guy and said.

#######

"Are you saying that Zhang Song is still fine in the iron-smelting yard, and the craftsmen in the iron-smelting yard didn't tie him up?" Yu Xinzhi asked with a gloomy face.

"Yes." The two attendants who had been to the ironworks just now replied in unison.

"Not only did the craftsmen not resent Zhang Song because of the increased tasks, but they were very friendly to him, and they didn't let him work, so that he could recuperate from his injuries with peace of mind?" Yu Xinzhi asked suspiciously.

"Yes."

"How is this possible?" Yu Xinzhi paced and thought, "Those craftsmen are obviously very afraid of things, knowing that Zhang Song is not dealing with us, how can they be so good to Zhang Song?" ”

Seeing that Yu Xinzhi fell into deep thought, and the matter was almost asked again, Chen Jia waved his hand to let the two entourages go down.

"Is there anything we can do about Zhang Song?" Yu Xinzhi was very unwilling.

"No, we still have a way." Chen Jia thought for a while and said.

"What's the solution?" Yu Xinzhi's eyes lit up and he stopped.

"From tomorrow onwards, we will not go to Zhang Song, but to trouble the blacksmiths until they hand Zhang Song over."

"Haven't we already troubled the blacksmiths? It's useless. Yu Xinzhi said disappointedly.

"No, it's useful to do it another way." Chen Jia said firmly, "We don't need to assign more tasks, we just need to beat the craftsmen every day." ”

"Why is it useless to assign more tasks, but it is useful to beat up craftsmen?" Yu Xinzhi still didn't quite understand, and looked at Chen Jia suspiciously.

Chen Jia patiently explained to Yu Xinzhi: "You think, if we assign more tasks, as long as they usually step up, they can complete it, even if they can't complete it, it will be a few days later, not to mention what if they can't be completed?" You must know that a lot of steel is needed in the valley during this time, and we can't kill the blacksmiths anymore. ”

Chen Jia paused for a moment, then continued: "The beating is different, there is no way to avoid it, and the beating every day will cause a lot of pressure on the craftsmen, because the craftsmen are beaten because of Zhang Song, if Zhang Song does not stand up, the craftsmen will resent him, isolate him, and eventually give him to us, if Zhang Song stands up, it will be better." ”

Yu Xinzhi carefully experienced it for a while, patted Chen Jia's shoulder suddenly, and said, "Okay, you are really my good military advisor, just do as you say." ”

Chen Jia smiled, he handed over the team to Zhong Lei and Fang Tao to manage, and he concentrated on accompanying Yu Xinzhi's side, just to win Yu Xinzhi's favor, and the future of Qingsong Valley belongs to Yu Xinzhi.

#######

The ironsmith returned to the ironwork in a sullen manner, and before looking for Zhang Song, he looked at the water to sort out the wounds on his face.

"Engong, the method you said is useless." After seeing Zhang Song, the iron guy said depressedly.

"What's wrong?" Zhang Song stopped thinking, "Did you tell Zhou Mingshu?" ”

"I told him." "I will also tell him what you have taught, and from tomorrow onwards, give us a stable environment, and the amount of iron smelted can be doubled." ”

Zhang Song nodded, he did teach the iron guy in this way.

"Did Zhou Mingshu say anything?"

The iron guy thought for a while and replied, "Zhou Mingshu didn't say anything, just let people drive me out." ”
