Not long after, a middle-aged man with a black and gray face came to Zhang Nan and Wei Tianwu, and saw that this person was a person who had been working for a long time. Pen "Fun" Pavilion www.biquge.info

The middle-aged man bowed and said, "I've seen my lord." ”

Wei Tianwu nodded and said, "Lord Zhang, this is the number one blacksmith in the Ministry of Industry, and he participated in the construction of this shaft furnace. Of course, since you proposed the system of grading craftsmen, Lord Zhang, this is the first person in my Datang to obtain a fourth-level blacksmith. Wei Tianwu said with a smile.

"Oh, it seems that this blacksmith must have something special." Zhang Nan also said with a smile.

"Don't dare to be, don't dare to be, after Xia Zida got the drawings of the shaft furnace for ironmaking, I have been wondering, who can come up with such a method to increase the output of iron, it must be you, Lord Zhang."

"That's right, that's me." Zhang Nan said with a smile.

"It's amazing. This shaft furnace has already thrown the raw iron in, and it will be immediately possible to know the output geometry. Blacksmith Ge smiled and looked at the small shaft furnace that was emitting black smoke.

Blacksmith Ge took Zhang Nan and Wei Tianwu to the shed not far from the shaft furnace, waiting for the final output.

When Zhang Nan drank the third bowl of water, a craftsman came to report, and the young craftsman looked excited. As soon as Zhang Nan saw the appearance of this craftsman, he knew that the iron output of this piece must not be low.

The young craftsman said in a trembling voice, "Master Wei, the iron is produced. ”

"Oh, how much is the yield?" When Wei Tianwu heard that he had come out, he hurriedly asked.

"The yield is ten times higher than the previous ironmaking method!" The young craftsman said excitedly.

"Ten times!" Blacksmith Ge stood up with a smack.

It's no wonder that Blacksmith Ge is so excited, mainly because the current shaft furnace is still a miniature version, not the original, it is ten times more than the previous output, if the original shaft furnace is used, it is not to take off.

Wei Tianwu was also very excited when he heard this output.

"Master Zhang is really a genius, this shaft furnace is really useful, great, I'll report it to the emperor." After Wei Tianwu finished speaking, he prepared to go to Li Er. was stopped by Zhang Nan.

"Master Wei, don't worry." Zhang Nan said.

"Why did Lord Zhang stop me, how could I not tell the emperor about such gratifying news." Wei Tianwu asked strangely.

"Master Wei, you think, this shaft furnace is just an experiment, and the original shaft furnace will be built soon. Why not wait until the original shaft furnace is built, let the emperor come to see it in person, and intuitively see the output here, it is best to practice again with the previous iron-making method, there is a comparison between the two, then the emperor must be more happy. Zhang Nan said.

Wei Tianwu thought about it, Zhang Nan did have some truth in what he said, so he dispelled the idea of entering the palace to report the good news to Li Er.

Just as the crowd was delighted with the tenfold increase in production, the stove not far away made a clicking sound.

"Master Zhang, did you hear anything?" Wei Tianwu first heard the clicking sound of the shaft furnace and asked strangely.

Zhang Nan listened carefully, and there was indeed a strange "click" sound, and said, "I heard it, where did this come from?" ”

Everyone heard the "click" sound, so they began to find out where the "click" sound came from.

Ge Blacksmith was the first to notice, "Adults, this clicking sound seems to come from the shaft furnace." A few people listened carefully, and it was indeed a sound coming from the shaft furnace.

"Strange, why does it make a "click" sound? Blacksmith, did you have this voice in the past when you made iron? Zhang Nan asked.

"When I go back to my lordship, there is no such voice." It was the first time that the blacksmith had heard this voice, and it was very strange.

At this time, Zhang Nan paid attention to the shaft furnace, Zhang Nan didn't care about it, his hairs stood up, because he saw the earthen shaft furnace, and a crack appeared visible to the naked eye, and the crack was still expanding, making a "click" sound.

"Run, run, run as far as possible." Zhang Nan shouted loudly, after speaking, Zhang Nan ran away, and flew separately when the disaster came, he was not a living Lei Feng, he saw that the situation was wrong, or more important than anything else, he still had a daughter-in-law waiting to marry, and he couldn't die under this shaft furnace.

Hearing Zhang Nan's shout, a group of people suddenly scattered, anyway, the officials all ran away, what are you waiting for if you don't run?

Sure enough, as soon as he ran to the back of the small shed, Zhang Nan heard a "boom" behind him, and when he looked around, the hot molten iron was flowing on the ground.

In the past, I heard the explosion of a certain steel mill on the news, but now the shaft furnace explosion happened in front of him, Zhang Nan thought about it, and couldn't help but feel a little afraid.

"Lord Zhang, why do you want to blow up the oven? What the hell is going on. Wei Tianwu looked at the molten iron all over the ground, and also shuddered.

"How did I know I could fry? It must have been when making the shaft furnace, which step went wrong, and my drawings were absolutely fine. Zhang Nan said firmly that he may make mistakes, but the system will definitely not make mistakes.

"Master Zhang, let's get out of here first, and then go back to the Ministry of Engineering to talk about this matter."

The frightened two left the shaft furnace and returned to the Ministry of Engineering, and after drinking several cups of tea in one go, Zhang Nan felt that his hands began to warm up.

"Master Zhang, I advise you to enter the palace to find the emperor." Wei Tianwu also drank several cups of tea in a row before he spoke.

"Looking for the emperor? Why do you want to find the emperor? Zhang Nan asked strangely.

"Lord Zhang, this is such a big thing, don't you tell the emperor first? Although no one died just now, tomorrow those officials will definitely be moved by the wind and will refer to you in the court. Wei Tianwu said.

"Join me? What does it matter to me, it's not a shaft furnace I built, this fryer, why can't it be relied on on my head. Zhang Nan said.

"Eh, Lord Zhang, you don't know those officials. Those people are people who are looking for things for others for a day, and if they don't look for things for a day, they are uncomfortable. Wei Tianwu said.

"Lord Zhang, you don't know, although you are good friends with many adults in the court, these officials have long seen you unpleasantly, and they have been waiting for you to make mistakes, so that you can participate in a copy in front of the emperor." Wei Tianwu continued.

"Why don't you look at me, I didn't offend them." Zhang Nan thought about it, and really didn't offend those officials.

"Eh, Lord Zhang doesn't know, since the emperor recruited you into the imperial court, Lord Zhang, you have risen to the top, but how do these officials know what the things that Lord Zhang has done mean to my Tang Dynasty, they all think that Lord Zhang is just a charlatan." Wei Tianwu sighed and said.

"This, and this kind of thing?" Zhang Nan said strangely.
